practical performance

Students in vocational practical courses start with uneven skills, so an instructional model has to cope with that gap without losing sight of individual accountability. This quasi-experimental pretest–posttest study compared Team Assisted Individualization (TAI) with conventional instruction in a Fabric Embellishment Techniques course of a Diploma III Fashion Design program. Two intact parallel classes of 13 students each (N = 26) took part in the second semester of academic year 2024–2025, and a lottery decided which class received TAI. Practical performance was scored on a 0–100 scale before and after instruction. The TAI class rose from 72.38 to 88.85 and the conventional class from 70.77 to 81.31, mean gains of 16.46 and 10.54 points. The classes did not differ significantly at pretest (p = .231), although the TAI class started 1.62 points higher. At posttest the difference was 7.54 points, t(24) = 4.42, p < .001, and the difference in gains was 5.92 points, t(24) = 6.48, p < .001. Because each condition was delivered to a single intact class, these student-level tests cannot separate the teaching model from class-specific influences, and the results are best treated as preliminary evidence.

This study aimed to develop and examine the validity, practicality, and preliminary effectiveness of the Outcome-Based Authentic Learning Model (OBALM) for strengthening the professional competence of prospective vocational educators. This Research and Development (R&D) study employed the ADDIE model and involved 54 third-semester students of the Vocational Makeup Education Study Program at the Indonesian Institute of the Arts Padangpanjang. Data were collected through expert validation, implementation observations, student responses, and a professional performance rubric, and were analyzed using Aiken’s V, percentage scores, N-gain, and inferential statistics. OBALM comprises six stages: Authentic Problem Orientation, Problem Analysis, Strategy Design, Implementation, Feedback, and Reflection. Expert validation yielded an Aiken’s V of 0.89, indicating high content validity, while the overall practicality score was 85.0%. Students’ mean professional competence score increased from 62.18 to 82.94, with an N-gain of 0.55. The pretest–posttest difference was statistically significant, t(53) = 13.44, p < .001, with a very large effect size (Cohen’s dz = 1.83). Improvements were observed across the seven targeted professional competence dimensions. These findings provide initial empirical support for OBALM as a structured learning approach that integrates outcome-based learning, authentic problems, practical performance, feedback, and reflection in vocational higher education. Keywords: outcome-based education, authentic learning, professional competence, vocational education, instructional model.

This study examines the status of science identity of physics among middle school students, adopting a mixed-methods approach combining survey data and qualitative interviews, thereby addressing a gap in research on science identity in physics within the transitional context from integrated to discipline-specific curricula in early middle school. Quantitative analyses, including descriptive statistics, cluster analysis, correlation analysis, t-tests, and MANOVA, examined students’ science identity status, patterns, and gender differences. Qualitative interviews were analyzed using reflexive thematic analysis to explore underlying factors. The findings indicate that students’ science identity is moderately positive overall but characterized by an internal imbalance. While interest in science classes emerges as the strongest dimension, science role recognition remains notably weak, revealing an interest–recognition gap. A substantial proportion of students cluster within a neutral identity category, suggesting that the transition from integrated science to subject-based curricula represents a critical and malleable stage in identity development. Gender differences are significant across all dimensions of science identity and become more pronounced at higher grade levels, particularly in learning competence, practical performance, and career interest. Qualitative evidence suggests that these patterns may be associated with increasing academic demands following the transition to discipline-specific curricula, shifts in evaluation approaches, and internalized gender stereotypes. Additionally, limited peer discourse, low perceived proximity to the scientist role, and insufficient exposure to authentic scientific practices further constrain identity formation. Teacher recognition is a critical factor, with female students showing heightened sensitivity to it.

این پژوهش به بررسی وضعیت هویت علمی در فیزیک در میان دانش‌آموزان دوره متوسطه اول می‌پردازد و با اتخاذ رویکردی ترکیبی که داده‌های پیمایشی و مصاحبه‌های کیفی را تلفیق می‌کند، به خلأ پژوهشی در زمینه هویت علمی در فیزیک در بستر گذار از برنامه درسی تلفیقی به برنامه درسی مبتنی بر رشته‌های مجزا در اوایل دوره متوسطه پاسخ می‌دهد. تحلیل‌های کمی، شامل آمار توصیفی، تحلیل خوشه‌ای، تحلیل همبستگی، آزمون t و تحلیل واریانس چندمتغیره (MANOVA)، وضعیت، الگوها و تفاوت‌های جنسیتی هویت علمی دانش‌آموزان را بررسی کردند. مصاحبه‌های کیفی با استفاده از تحلیل تماتیک بازتابی برای شناسایی عوامل زمینه‌ای تحلیل شدند. یافته‌ها نشان می‌دهد که هویت علمی دانش‌آموزان به طور کلی در سطحی نسبتاً مثبت قرار دارد اما با عدم تعادل درونی همراه است. در حالی که علاقه به کلاس‌های علوم قوی‌ترین بُعد هویت است، شناسایی نقش علمی به طور قابل توجهی ضعیف باقی می‌ماند و شکاف علاقه ـ شناسایی را آشکار می‌سازد. بخش قابل توجهی از دانش‌آموزان در دسته هویت خنثی قرار می‌گیرند که نشان می‌دهد گذار از علوم تلفیقی به برنامه درسی مبتنی بر رشته، مرحله‌ای بحرانی و انعطاف‌پذیر در رشد هویت به شمار می‌رود. تفاوت‌های جنسیتی در همه ابعاد هویت علمی معنادار است و در پایه‌های بالاتر، به ویژه در شایستگی یادگیری، عملکرد عملی و علاقه شغلی، برجسته‌تر می‌شود. شواهد کیفی حاکی از آن است که این الگوها ممکن است با افزایش انتظارات تحصیلی پس از گذار به برنامه درسی مبتنی بر رشته، تغییر رویکردهای ارزشیابی و درونی‌سازی کلیشه‌های جنسیتی مرتبط باشد. همچنین، محدودیت در گفت‌وگوی همسالان، ادراک پایین از نزدیکی به نقش دانشمند و مواجهه ناکافی با تجارب اصیل علمی، شکل‌گیری هویت را بیشتر محدود می‌کند. شناسایی معلم به عنوان عاملی کلیدی مطرح است و دانش‌آموزان دختر حساسیت بیشتری نسبت به آن نشان می‌دهند.
