experimentation

Problem-solving skills are essential to develop in early childhood so that children can identify problems, consider alternatives, and determine solutions independently. However, teacher-centered learning may limit children's opportunities to explore and experiment with different problem-solving strategies. This study aims to describe the implementation of the Science, Technology, Engineering, Arts, and Mathematics (STEAM) approach using loose parts materials and the development of early childhood problem-solving skills. A qualitative descriptive method was employed at RA Nurhayati, Medan Tembung, involving teachers and 30 children aged 5–6 years. Data were collected through observation, interviews, and documentation, with credibility supported by triangulation of techniques and sources. The findings indicate that constructing a bridge for toy cars provided opportunities for children to identify problems, select materials, design solutions, test alternatives, revise constructions, and evaluate outcomes. Children also engaged in experimentation, communication, collaboration, and creative material use. These findings suggest that the STEAM approach using loose parts can support the development of early childhood problem-solving skills through active, contextual, and child-centered learning experiences. ABSTRAK Keterampilan pemecahan masalah (problem solving) penting dikembangkan sejak usia dini agar anak mampu mengenali permasalahan, mempertimbangkan alternatif, dan menentukan solusi secara mandiri. Namun, pembelajaran yang masih berpusat pada guru dapat membatasi kesempatan anak untuk bereksplorasi dan mencoba berbagai strategi penyelesaian masalah. Penelitian ini bertujuan untuk mendeskripsikan penerapan pendekatan Science, Technology, Engineering, Arts, and Mathematics (STEAM) berbasis media loose parts serta perkembangan keterampilan pemecahan masalah anak usia dini. Penelitian ini menggunakan pendekatan kualitatif dengan metode deskriptif di RA Nurhayati, Kecamatan Medan Tembung, dengan melibatkan guru dan 30 anak usia 5–6 tahun. Data dikumpulkan melalui observasi, wawancara, dan dokumentasi, serta diperiksa melalui triangulasi teknik dan sumber. Hasil penelitian menunjukkan bahwa kegiatan merancang jembatan untuk mobil mainan memberikan kesempatan kepada anak untuk mengidentifikasi masalah, memilih bahan, merancang solusi, mencoba alternatif, memperbaiki konstruksi, dan mengevaluasi hasil. Anak juga menunjukkan keterlibatan dalam eksperimen, komunikasi, kolaborasi, dan penggunaan material secara kreatif. Dengan demikian, pendekatan STEAM berbasis media loose parts berpotensi mendukung perkembangan keterampilan pemecahan masalah melalui pengalaman belajar yang aktif, kontekstual, dan berpusat pada anak.

This research explores how learning science through Project-Based Learning (PBL) can increase student engagement by influencing student interest and academic performance in the 7th-grade classroom. While elementary students often enjoy science because it is very hands-on, middle school introduces a more structured instruction, which can reduce student motivation and lead to a decrease in engagement. This study sought to understand whether Project-Based Learning (PBL) could help bridge the gap between engagement and rigor. PBL provides students with opportunities to explore authentic, real-world problems, collaborate with peers, and apply scientific concepts in meaningful contexts. Students actively construct knowledge through inquiry, experimentation, and reflection. These elements align closely with the goals of middle school science education—to foster critical thinking, creativity, and problem-solving skills while maintaining student interest and joy in learning. The study was conducted in two 7th-grade science classrooms, one of which included a dual-language Spanish program. Students participated in science units designed around PBL principles that emphasized inquiry-based projects, collaboration, and student choice. Data were collected using pre- and post-interest surveys and pre- and post-unit assessments to measure shifts in student attitudes, engagement, and academic performance.

Background: Teacher agency is essential to educational transformation, yet teacher development in Nepal often relies on standardized training approaches that emphasize prescribed methods rather than critical reflection, contextual experimentation, and collaborative learning. Objectives: This study explores how teachers develop and exercise agency through Critical–Creative Pedagogy (CCP) and participatory action research in two Nepali public-school contexts. Methods: Using a participatory action research approach, the study examined two contexts: a cross-school initiative involving 11 teachers from eight public schools in Helambu and a school-based initiative involving 30 teachers at Janata Secondary School in Bardibas. Data were generated over nine months through workshop interactions, teacher reflections, lesson plans, classroom observations, reflective dialogues, and informal conversations with students. The analysis examined how reflection, dialogue, classroom experimentation, and collective professional learning contributed to the development of teacher agency. Results: The findings indicate that teacher agency developed through iterative cycles of reflection, action, observation, dialogue, and re-reflection rather than through standardized training alone. Teachers began questioning textbook-centred and examination-driven practices and experimenting with learning activities grounded in students’ experiences and local contexts. Contextual adaptation and engagement with the wider school community, including school management committees and parents, emerged as important dimensions of pedagogical change. The Bardibas initiative appeared to foster stronger shared reflection, mutual support, and continuity of pedagogical change than the cross-school arrangement in Helambu. Conclusion: Teacher agency is a relational and context-dependent process that develops through critical reflection, pedagogical experimentation, and collaborative learning. Sustaining educational transformation requires professional learning opportunities that connect teachers’ agency with local knowledge, school-level collaboration, and community engagement. Novelty: By examining participatory action research across two distinct school contexts, this study highlights how the institutional setting of teacher collaboration may shape opportunities for collective reflection, mutual support, and sustained pedagogical change. It also foregrounds the importance of connecting teacher learning with school and community contexts in efforts to transform classroom practice.

Purpose: to explore the use of nature-based loose parts in supporting young children’s creativity through material exploration, independent choice, experimentation, and open-ended play at PAUD Kiddy Kid Center, Banda Aceh. Method: this study employed a qualitative descriptive approach at PAUD Kiddy Kid Center, Banda Aceh. Participants included four young children and their teacher, selected purposively. Data were collected through observation, semi-structured interviews, and documentation, then analyzed using the interactive model of Miles, comprising data reduction, data display, and conclusion drawing. Findings: nature-based loose parts provided opportunities for children to express creativity through material exploration, independent selection, experimentation, material combination, imagination, and the development of diverse creations. All four observed children demonstrated the identified creative behaviors, although their participation pace varied. Teachers facilitated these processes through careful material preparation, safety supervision, and open-ended guidance. Despite challenges in material storage and hygiene, nature-based loose parts offered an accessible and flexible learning resource that supported creative engagement beyond the final product. Implications: PAUD educators can use accessible natural materials to create open-ended learning activities that encourage children’s creativity, independence, and exploration. Originality: lies in its process-oriented examination of how children explore, select, combine, and transform nature-based loose parts, emphasizing creative processes rather than finished products.

The article examines the impact of information and communication technologies (ICT) on the development of mathematical abilities and geometric concepts in preschool children. The object of the research is the process of developing mathematical abilities and geometric concepts in older preschool children. The aim of the article is to identify the pedagogical potential of ICT and evaluate its effectiveness in developing these abilities. The research methods include the analysis of scientific and methodological literature, pedagogical observation, game-based learning, pedagogical experimentation, and comparative analysis of the results.

The methodologies of ICT-mediated learning and game-based learning were applied. The research outcomes indicate that the purposeful use of ICT contributes to the development of children's abilities to recognize, name, compare, and classify geometric shapes. It also promotes children's cognitive engagement, logical and spatial thinking, attention, and memory. The experimental results further revealed increased children's engagement and learning motivation. The conclusion of the study is that the pedagogically justified integration of information and communication technologies into game-based learning is an effective means of developing mathematical abilities and geometric concepts in preschool children, facilitating a more visual, interactive, and child-centered learning process.

Background and Objectives: Architectural spaces are often designed with a strong visual focus, yet their sonic potential remains underexplored. Inspired by the concept of “breathing” that symbolizes life, movement, and vitality, the research project Prana aimed to create a responsive sound installation that enhances the sonic environment in architectural spaces by utilizing efficient wireless communication, sensors, and algorithms, which can evoke the feeling of breathing life into a space, providing visitors with a novel and engaging sensory experience. The designed system offered flexibility for placement and adaptation across various locations. Conducted within the tunnel of Wat Umong in Chiang Mai, Thailand, the exhibition was presented to the public, and the author collected data from visitors for the evaluation. This project serves as an example of how interactive sound design can revitalize architectural environments by creating a dialogue between sound, space, and audience. Methods: The study adopts both research-led and practice-led approaches, examining the interplay between technical design and aesthetic expression. The author collected ideas and designed the technical process of developing interactive sound installation, environmental sound design, multi-channel sound system, and wireless communication to develop the installation. The process of developing and installing the work was closely documented, while visitor experiences were assessed through direct observation and questionnaires during the exhibition period for the evaluation. The collected data was analyzed and presented as results in two aspects, sound design and system design. Results: The sound installation utilized microcontrollers (Arduino) and radio transceivers to process signals from two selected sensors (photoelectric sensor and electric gyroscope) encapsulated in small bells as triggers for algorithmically projecting prepared sounds through a multichannel sound system. The electric gyroscope has been proven to be more effective in representing the movement of the bell in the form of digital data. The collected data from the exhibition reveals that a coherent relationship between sound installation, spatial context, and environmental soundscape forms a vital foundation for innovative sound design. Audience responses emphasized that engagement and satisfaction largely depend on the immersive and experiential qualities of the work, highlighting the significance of site-responsive experimentation and clear design intentions. Conclusions: The Prana project demonstrates how interactive sound design can meaningfully enrich architectural environments by integrating technology, spatial awareness, and aesthetic intention. The findings show that when sound, space, and audience interaction are thoughtfully aligned, architectural settings can be transformed into dynamic, sensory experiences that evoke vitality and presence, much like the metaphor of breathing that inspired the work. Technically, the use of microcontrollers, wireless communication, and motion-based sensing proved effective in creating a flexible and responsive sonic system, with the electric gyroscope offering particularly reliable data for movement-triggered sound generation in this project. Audience feedback confirmed that the success of such installations depends not only on technological capability but also on the experiential coherence and immersion they create. This highlights the importance of site-specific testing, deliberate sound selection, and a clear conceptual foundation. Ultimately, the project offers a practical and artistic framework for future interactive sound installations, highlighting how responsive technologies can animate architectural spaces and foster deeper engagement through sound. Furthermore, developing simple and user-friendly interfaces can extend the accessibility of interactive sound installations.

The article discusses the synergetic approach to teaching chess—specifically, methods aimed at system comprehension, information processing, and child development—which can lead to the self-organization of the child's cognitive activity within the context of the cognitive schema proposed by Jean Piaget. The aim of the article is to substantiate the synergetic effects involved in the process of a preschooler's development. Research methodology and selected methods. Methodologically, we drew upon general systems theory, structural and functional approaches to chess instruction, and the theoretical and applied developments regarding the "activity concept"—as well as theories of argumentation and personality development—formulated by L. Vygotsky, A. Leontiev, A. Luria, and their followers. The methods employed included the analysis of professional literature, observation (of both moves and emotional states), interviews, experimentation, and the analysis of results. The study’s ultimate finding is that, through trial and error, imitation, or precise instruction by an adult, the processes of assimilation and accommodation become accessible to the child; their combination yields synergistic effects, manifesting as the purposeful organization and management of educational-cognitive activity. Therefore, theoretical-applied approaches that generate synergistic effects during chess instruction are applicable to the developmental process of preschoolers. Main conclusion: The feasibility of employing approaches that yield synergistic effects in the development of preschoolers and the self-organization of their activities is demonstrated.

Basic science is concerned with developing an understanding of the natural world through observation, experimentation, investigation, and logical reasoning. The study compared the effectiveness of computer simulations and charts usage on secondary school students’ academic achievement in Basic Science in Aguata Education Zone of Anambra State. Two research questions and three hypotheses guided the study. A quasi-experimental design was adopted for the study. The population consisted of 3,310 (1,664 males and 1,646 females) Upper Basic Education Two (UB2) students who enrolled for the 2025/2026 academic session in the 39 public secondary schools in the Aguata Education Zone of Anambra State, with a sample of 186 UB2 Basic Science students selected using a multistage sampling procedure. The instrument for data collection was Basic Science Achievement Test (BSAT). The instrument was face validated by three experts and a reliability index of 0.87 was obtained using Kuder Richardson 20 method. Experimental procedure was carried out in stages and data were collected through pretest and posttest using BSAT. Data analysis was done using the mean and Analysis of Covariance at the 0.05 level of significance. Findings, among others, revealed that students taught Basic Science concepts using computer simulations achieved significantly higher scores than those taught using charts. Male students taught using computer simulations recorded slightly higher mean achievement scores than their female counterparts, but the difference was not significant. Based on the findings, the study recommended that Basic Science teachers should regularly use computer simulations during classroom instruction, as they significantly improve students’ achievement in Basic Science more than charts do.

علوم پایه به توسعه درک از جهان طبیعی از طریق مشاهده، آزمایش، تحقیق و استدلال منطقی می‌پردازد. این پژوهش اثربخشی استفاده از شبیه‌سازی‌های رایانه‌ای و نمودارها را بر پیشرفت تحصیلی دانش‌آموزان دبیرستانی در درس علوم پایه در منطقه آموزشی Aguata از ایالت Anambra مقایسه کرد. دو سؤال پژوهش و سه فرضیه، این مطالعه را هدایت کردند. طرح پژوهش شبه‌آزمایشی اتخاذ شد. جامعه آماری شامل ۳۳۱۰ دانش‌آموز (۱۶۶۴ پسر و ۱۶۴۶ دختر) پایه دوم متوسطه اول (UB2) بود که برای سال تحصیلی ۲۰۲۵/۲۰۲۶ در ۳۹ مدرسه متوسطه دولتی منطقه آموزشی Aguata ایالت Anambra ثبت‌نام کرده بودند و نمونه‌ای متشکل از ۱۸۶ دانش‌آموز علوم پایه UB2 با استفاده از روش نمونه‌گیری چندمرحله‌ای انتخاب شد. ابزار گردآوری داده‌ها، آزمون پیشرفت علوم پایه (BSAT) بود. این ابزار توسط سه نفر از خبرگان از نظر روایی صوری مورد تأیید قرار گرفت و شاخص پایایی ۰.۸۷ با استفاده از روش Kuder Richardson 20 به دست آمد. فرایند آزمایشی در مراحل مختلف اجرا شد و داده‌ها از طریق پیش‌آزمون و پس‌آزمون با استفاده از BSAT جمع‌آوری گردید. تحلیل داده‌ها با استفاده از میانگین و تحلیل کوواریانس در سطح معناداری ۰.۰۵ انجام شد. یافته‌ها، از جمله، نشان داد که دانش‌آموزانی که مفاهیم علوم پایه را با استفاده از شبیه‌سازی‌های رایانه‌ای فراگرفته بودند، به طور معناداری نمرات بالاتری نسبت به دانش‌آموزانی که با استفاده از نمودارها آموزش دیده بودند، کسب کردند. دانش‌آموزان پسر که با شبیه‌سازی رایانه‌ای آموزش دیده بودند، میانگین نمرات پیشرفت کمی بالاتر از همتایان دختر خود داشتند، اما این تفاوت معنادار نبود. بر اساس یافته‌ها، پژوهش توصیه کرد که معلمان علوم پایه به طور منظم از شبیه‌سازی‌های رایانه‌ای در آموزش کلاسی استفاده کنند، زیرا این روش به طور معناداری پیشرفت تحصیلی دانش‌آموزان در علوم پایه را بیش از نمودارها افزایش می‌دهد.

Attitudes towards socioscientific issues (SSIs) represent crucial learning dispositions, as they can influence the students’ willingness to engage with SSIs. Animal experimentation is a particularly contentious SSI, with attitudes ranging from rejection to acceptance. They are influenced by external factors (e.g., research context, test animal) and internal factors (e.g., knowledge, ethical aspects). Understanding these attitudes is essential for fostering reflective engagement with SSIs in higher education. This study ( N = 503) examines self-reported attitudes of pre-service teacher biology students and non-pre-service teacher biology students towards three contexts: animal experimentation with nonhuman primates, animal experimentation with other test animals, and behavioural research with nonhuman primates. It also explores the internal factors underlying these attitudes. Students’ attitudes differed across contexts: animal experimentation with nonhuman primates was viewed most critically, while behavioural research was perceived most favourably. Pre-service teacher students expressed more ambivalent and negative attitudes than non-pre-service teacher students. Regarding internal factors, a clear explanatory pattern emerged: “pro” attitudes were mainly explained by knowledge, “ambivalent” attitudes by conditions (e.g., the necessity of the research), and “contra” attitudes by ethical aspects. Pre-service teacher students consistently explained their attitudes with more references to knowledge than non-pre-service teacher students. These findings highlight the need for evidence-based integration of learning dispositions into science (teacher) higher education that explicitly addresses the SSI animal experimentation.

نگرش‌ها نسبت به مسائل اجتماعی-علمی (SSIها) به‌عنوان گرایش‌های یادگیری حیاتی تلقی می‌شوند، چرا که می‌توانند بر تمایل دانشجویان برای درگیر شدن با SSIها تأثیر بگذارند. آزمایش بر روی حیوانات یک SSI به‌ویژه بحث‌برانگیز است که نگرش‌ها نسبت به آن از رد تا پذیرش متغیر است. این نگرش‌ها تحت تأثیر عوامل بیرونی (مانند زمینه پژوهش، حیوان مورد آزمایش) و عوامل درونی (مانند دانش، جنبه‌های اخلاقی) قرار دارند. درک این نگرش‌ها برای تقویت مشارکت تأملی با SSIها در آموزش عالی ضروری است. این مطالعه (N = 503) نگرش‌های خودگزارش‌شده دانشجویان زیست‌شناسی معلم‌آموز و غیرمعلم‌آموز را نسبت به سه زمینه بررسی می‌کند: آزمایش بر روی حیوانات با نخستی‌های غیرانسانی، آزمایش بر روی حیوانات با سایر حیوانات آزمایشی، و پژوهش رفتاری با نخستی‌های غیرانسانی. همچنین عوامل درونی زیربنایی این نگرش‌ها را مورد بررسی قرار می‌دهد. نگرش دانشجویان در زمینه‌های مختلف متفاوت بود: آزمایش بر روی حیوانات با نخستی‌های غیرانسانی بیشترین انتقاد را برانگیخت، در حالی که پژوهش رفتاری مطلوب‌ترین تلقی شد. دانشجویان معلم‌آموز نگرش‌های مبهم‌تر و منفی‌تری نسبت به دانشجویان غیرمعلم‌آموز ابراز کردند. در خصوص عوامل درونی، الگوی تبیینی روشنی مشاهده شد: نگرش‌های «موافق» عمدتاً با دانش توضیح داده شد، نگرش‌های «مبهم» با شرایط (مانند ضرورت پژوهش)، و نگرش‌های «مخالف» با جنبه‌های اخلاقی تبیین شدند. دانشجویان معلم‌آموز به طور مداوم نگرش‌های خود را با ارجاع بیشتری به دانش نسبت به دانشجویان غیرمعلم‌آموز توضیح دادند. این یافته‌ها بر ضرورت ادغام مبتنی بر شواهد گرایش‌های یادگیری در آموزش عالی علوم (و تربیت معلم علوم) که به طور صریح به SSI آزمایش بر روی حیوانات می‌پردازد، تأکید می‌کند.

STEM education often marginalizes rural students by privileging urban-centric engineering standards and forms of technical representation. This study investigates how traditional agricultural knowledge can be translated into engineering design learning through a Culturally Responsive STEM (CR-STEM) approach in rural classrooms. Using a qualitative case study design, data were collected from 12 tenth-grade students through classroom observations, design activities, and student-generated artifacts during an engineering project. A six-phase thematic analysis revealed that integrating agricultural knowledge enabled students to transform everyday experiences into functional engineering strategies. Instead of relying on conventional two-dimensional technical drawings, students demonstrated sophisticated problem-solving through direct hands-on experimentation, material adaptation, and the adaptive use of locally available resources. However, the findings also revealed a pedagogical tension stemming from a disconnect between students’ practical skills and formal communication. While students demonstrated strong physical engineering competence during construction, they struggled with formal technical drawing and academic presentation, which constrained their ability to articulate and formalize their design reasoning. These findings suggest that culturally responsive STEM education should support students in translating tacit local expertise into formal engineering representations. The study contributes to discussions on equitable STEM education by proposing alternative approaches to recognizing and assessing rural engineering competencies in culturally diverse learning contexts.

آموزش STEM اغلب با برتری دادن به استانداردهای مهندسی و شیوه‌های فنی مبتنی بر شهر، دانش‌آموزان روستایی را به حاشیه می‌راند. این پژوهش بررسی می‌کند که چگونه دانش کشاورزی سنتی می‌تواند از طریق رویکرد آموزش STEM پاسخگو به فرهنگ (CR-STEM) به یادگیری طراحی مهندسی در کلاس‌های روستایی ترجمه شود. با استفاده از طرح مطالعه موردی کیفی، داده‌ها از ۱۲ دانش‌آموز پایه دهم از طریق مشاهده کلاس، فعالیت‌های طراحی و آثار تولیدشده توسط دانش‌آموزان در طول یک پروژه مهندسی گردآوری شد. تحلیل تماتیک شش‌مرحله‌ای نشان داد که ادغام دانش کشاورزی به دانش‌آموزان امکان داد تا تجربیات روزمره خود را به راهبردهای مهندسی کاربردی تبدیل کنند. به جای اتکا به نقشه‌های فنی دوبعدی متعارف، دانش‌آموزان از طریق آزمایش عملی مستقیم، سازگاری با مواد و استفاده تطبیقی از منابع محلی موجود، حل مسئله پیشرفته‌ای را به نمایش گذاشتند. با این حال، یافته‌ها همچنین به وجود یک تنش آموزشی ناشی از گسست میان مهارت‌های عملی دانش‌آموزان و ارتباط رسمی اشاره داشت. در حالی که دانش‌آموزان در حین ساخت، شایستگی مهندسی فیزیکی بالایی نشان دادند، اما در ترسیم فنی رسمی و ارائه علمی با دشواری مواجه بودند که این امر توانایی آن‌ها را در بیان و صورت‌بندی استدلال طراحی‌شان محدود می‌کرد. این یافته‌ها نشان می‌دهد که آموزش STEM پاسخگو به فرهنگ باید از دانش‌آموزان در ترجمه تخصص ضمنی محلی به بازنمایی‌های رسمی مهندسی حمایت کند. این مطالعه با پیشنهاد رویکردهای جایگزین برای شناسایی و ارزیابی شایستگی‌های مهندسی روستایی در بسترهای یادگیری فرهنگی متنوع، به بحث‌های مربوط به آموزش عادلانه STEM کمک می‌کند.

The integration of coding and Artificial Intelligence (AI) into vocational education is essential for equipping students with 21st-century digital competencies, yet implementation in remote and island regions like Bangka Belitung archipelago province remains fragmented and unsustainable. This study employs Developmental Evaluation (DE) a real-time, adaptive, and participatory evaluation approach (Patton, 2011) to analyze policy readiness and strengthen the digital ecosystem for coding and AI instruction across vocational schools in the province. Using qualitative methods, including in- depth interviews (n = 26), focus group discussions, classroom observations, and policy document analysis, the research assesses readiness across five core dimensions: (1) policy & governance, (2) human capacity, (3) digital infrastructure, (4) curriculum relevance, and (5) industry–academia partnerships. Findings reveal a critical policy–practice gap: while national frameworks such as the Grand Design for Vocational School Revitalization and Kurikulum Merdeka promote digital literacy, local implementation lacks binding regional regulations, standardized teacher competency pathways, equitable infrastructure distribution, and context-based curricula. Only 24% of ICT teachers had received AI-related training, and AI concepts were rarely taught in practice. Through DE cycles of exploration, collective sense-making, and prototyping, stakeholders co-designed adaptive solutions including a provincial roadmap for digital vocational education, offline AI learning modules via WhatsApp, and micro-innovation grants for teacher-led experimentation. The study demonstrates DE’s effectiveness in fostering adaptive capacity, surfacing systemic barriers, and enabling locally owned, sustainable digital transformation strategies.

ادغام برنامه‌نویسی و هوش مصنوعی (AI) در آموزش فنی‌وحرفه‌ای برای تجهیز دانش‌آموزان به شایستگی‌های دیجیتال قرن بیست‌ویکم ضروری است، اما اجرای آن در مناطق دورافتاده و جزیره‌ای مانند استان مجمع‌الجزایر بانگکا بلیتونگ همچنان پراکنده و ناپایدار باقی مانده‌است. این مطالعه با بهره‌گیری از رویکرد ارزیابی توسعه‌ای (DE) که یک روش ارزیابی بلادرنگ، تطبیقی و مشارکتی است (Patton, 2011)، به تحلیل آمادگی سیاستی و تقویت زیست‌بوم دیجیتال برای آموزش برنامه‌نویسی و هوش مصنوعی در مدارس فنی‌وحرفه‌ای این استان می‌پردازد. با استفاده از روش‌های کیفی، از جمله مصاحبه‌های عمیق (n = 26)، بحث‌های گروهی متمرکز، مشاهده کلاس درس و تحلیل اسناد سیاستی، پژوهش آمادگی را در پنج بُعد اصلی ارزیابی می‌کند: (۱) سیاست و حکمرانی، (۲) ظرفیت انسانی، (۳) زیرساخت دیجیتال، (۴) ارتباط برنامه‌درسی و (۵) مشارکت صنعت و دانشگاه. یافته‌ها شکاف مهمی میان سیاست و عمل را نشان می‌دهد: در حالی که چارچوب‌های ملی مانند طرح کلان نوسازی مدارس فنی‌وحرفه‌ای و «کریکولوم مردکا» سواد دیجیتال را ترویج می‌کنند، اجرای محلی فاقد مقررات منطقه‌ای الزام‌آور، مسیرهای استاندارد شایستگی معلمان، توزیع عادلانه زیرساخت و برنامه‌درسی مبتنی بر زمینه است. تنها ۲۴٪ از معلمان ICT آموزش مرتبط با AI را دریافت کرده‌اند و مفاهیم AI به ندرت در عمل تدریس می‌شود. از طریق چرخه‌های DE شامل اکتشاف، معنا‌بخشی جمعی و نمونه‌سازی، ذینفعان راه‌حل‌های تطبیقی از جمله نقشه‌راه استانی برای آموزش دیجیتال فنی‌وحرفه‌ای، ماژول‌های یادگیری AI آفلاین از طریق WhatsApp و گرنت‌های خرد نوآوری برای آزمایشگری معلمان را به‌طور مشترک طراحی کردند. این مطالعه اثربخشی DE را در تقویت ظرفیت تطبیقی، آشکارسازی موانع نظام‌مند و امکان‌پذیر ساختن راهبردهای تحول دیجیتال بومی و پایدار نشان می‌دهد.

Introduction Hands-on laboratory experimentation is an important contributor to the successful acquisition of conceptual science knowledge, but its practical application has several limitations. Virtual laboratory experiments help overcome most of these shortcomings and may also be more effective than hands-on laboratory activities in promoting conceptual science knowledge acquisition. Methods In this study, the impact of virtual and hands-on laboratory experimentation on the acquisition of conceptual science knowledge was compared by means of a meta-analysis. The meta-analysis encompassed 43 studies selected according to the predefined inclusion criteria, and the principles of Preferred Reporting Items for Systematic reviews and Meta-Analyses procedure. For each study, one effect size value of Hedges' g was calculated. Subsequently, due to their heterogeneity, the overall effect size value was computed through the use of the random-effects model. Results Based on the obtained results [ g = 0.551, SE = 0.097, 95% CI (0.362, 0.740), p < 0.001] virtual laboratory experimentation appears to be significantly more effective in promoting the acquisition of conceptual science knowledge than experimentation conducted in hands-on laboratories. Furthermore, the meta-regression results suggest that the effectiveness of virtual laboratory experiments may not be moderated by the geographical location, science subject area, methodological quality of included studies, 2D/3D design type, delivery format, learner agency, and software type of virtual laboratories, the duration of their application, or the assessment format used to evaluate conceptual knowledge acquisition. Conversely, virtual laboratory experimentation seems to be significantly more effective when implemented at the secondary school as opposed to the university level ( p = 0.014) and when experimental activities were conducted individually rather than within groups ( p = 0.008). Conclusions Research results suggest significantly stronger positive impact of virtual laboratory experimentation on the acquisition of conceptual science knowledge and provide potentially important guidelines for both its practical application and future research in this field.

مقدمه: آزمایش‌های عملی در آزمایشگاه نقش مهمی در موفقیت کسب دانش مفهومی علوم ایفا می‌کنند، اما کاربرد عملی آن‌ها با محدودیت‌هایی همراه است. آزمایش‌های آزمایشگاهی مجازی به رفع بسیاری از این کاستی‌ها کمک می‌کنند و ممکن است در ارتقای کسب دانش مفهومی علوم، مؤثرتر از فعالیت‌های عملی آزمایشگاهی باشند. روش‌ها: در این مطالعه، تأثیر آزمایش‌های آزمایشگاهی مجازی و عملی بر کسب دانش مفهومی علوم از طریق یک فراتحلیل مقایسه شد. فراتحلیل شامل ۴۳ مطالعه بود که بر اساس معیارهای از پیش تعیین‌شده وارد شده و مطابق با اصول رویه‌ی Preferred Reporting Items for Systematic reviews and Meta-Analyses انجام شد. برای هر مطالعه، یک مقدار اندازه‌ی اثر از نوع g هجز محاسبه گردید. سپس، به دلیل ناهمگنی مطالعات، مقدار کلی اندازه‌ی اثر با استفاده از مدل اثرات تصادفی محاسبه شد. نتایج: بر اساس نتایج به‌دست‌آمده [g = 0.551, SE = 0.097, 95% CI (0.362, 0.740), p < 0.001]، آزمایش‌های آزمایشگاهی مجازی به طور معناداری در ارتقای کسب دانش مفهومی علوم مؤثرتر از آزمایش‌های عملی آزمایشگاهی هستند. همچنین، نتایج فراتحلیل رگرسیون نشان می‌دهد که اثربخشی آزمایش‌های آزمایشگاهی مجازی ممکن است تحت تأثیر محل جغرافیایی، حوزه‌ی موضوعی علوم، کیفیت روش‌شناختی مطالعات واردشده، نوع طراحی دو‌بعدی/سه‌بعدی، قالب ارائه، عاملیت یادگیرنده، نوع نرم‌افزار آزمایشگاه مجازی، مدت زمان استفاده یا قالب ارزیابی مورد استفاده برای سنجش کسب دانش مفهومی قرار نگیرد. در مقابل، آزمایش‌های آزمایشگاهی مجازی زمانی که در سطح دبیرستان نسبت به سطح دانشگاه اجرا می‌شوند (p = 0.014) و زمانی که فعالیت‌های آزمایشی به صورت فردی و نه گروهی انجام می‌شوند (p = 0.008)، به طور معناداری مؤثرتر به نظر می‌رسند. نتیجه‌گیری: نتایج پژوهش حاکی از تأثیر مثبت و معنادار قوی‌تر آزمایش‌های آزمایشگاهی مجازی بر کسب دانش مفهومی علوم است و راهنمایی‌های بالقوه مهمی برای کاربرد عملی و پژوهش‌های آتی در این حوزه ارائه می‌دهد.

Abstract The rise of the BE V ing progressive has been argued to reflect a broader shift in the typological profile of English from a bounded to an unbounded language, leading to changing preferences in aspectual construal and narrative organization. However, it remains unclear whether BE V ing directly replaced a dominant pattern of bounded event construal or superseded alternative strategies that were already available to express progressive(-like) meaning before. The idea of a typological shift suggests that many more strategies may have been involved. This article investigates diachronic change in the expression of progressive(-like) meaning. To this end, use is made of a historical parallel translation corpus consisting of eight successive English translations of Cervantes’ Don Quijote , giving insight into how the same meanings were expressed over time. The results suggest that the expression of progressive(-like) meaning in English went through a pragmatic stage, in which progressive meaning was mainly expressed through invited inference, followed by an experimentation stage, during which speakers of English resorted to a variety of lexical and (semi-)grammatical options to express these meanings semantically, and resulting in the current situation with the emergence of the grammaticalized marker BE V ing as an uncontested default coding option.

چکیده: رشد ساختار BE V ing استمراری به عنوان بازتابی از یک تغییر گسترده‌تر در نمایه نوع‌شناختی زبان انگلیسی از یک زبان محدود به زبان نامحدود مطرح شده است که منجر به تغییر ترجیحات در برداشت وجهی و سازماندهی روایی می‌شود. با این حال، هنوز مشخص نیست که آیا BE V ing مستقیماً جایگزین الگوی غالب برداشت رویداد محدود شده است یا بر استراتژی‌های جایگزینی که پیش‌تر برای بیان معنای استمراری (یا مشابه استمراری) در دسترس بودند، برتری یافته است. ایده تغییر نوع‌شناختی نشان می‌دهد که استراتژی‌های بسیار بیشتری ممکن است درگیر بوده باشند. این مقاله به بررسی تغییرات تاریخی در بیان معنای استمراری (یا مشابه استمراری) می‌پردازد. بدین منظور، از یک پیکره موازی ترجمه تاریخی شامل هشت ترجمه متوالی انگلیسی از «دون کیشوت» اثر سروانتس استفاده شده است که بینشی درباره چگونگی بیان همان معانی در طول زمان ارائه می‌دهد. نتایج نشان می‌دهد که بیان معنای استمراری (یا مشابه استمراری) در زبان انگلیسی از یک مرحله کاربردشناختی عبور کرده است که در آن معنای استمراری عمدتاً از طریق استنتاج دعوت‌شده بیان می‌شد، و پس از آن مرحله‌ای از آزمایش‌گری رخ داده است که در آن گویشوران انگلیسی برای بیان این معانی به گزینه‌های واژگانی و (نیمه)دستوری متعددی متوسل شدند، و در نهایت به وضعیت کنونی با ظهور نشانگر دستوری‌شده BE V ing به عنوان گزینه پیش‌فرض و بی‌رقیب رمزگذاری رسیده است.
