Abstract

Rendahnya capaian literasi matematika siswa Indonesia pada PISA 2022 mengindikasikan perlunya model pembelajaran yang mampu meningkatkan kemampuan kognitif dan metakognitif. Model pembelajaran IMPROVE, yang menekankan langkah metacognitive questioning dan self-regulated learning, diyakini dapat meningkatkan berbagai aspek kemampuan matematis. Penelitian ini bertujuan menentukan pengaruh model IMPROVE terhadap kemampuan matematis melalui meta-analisis, sekaligus mengidentifikasi efektivitasnya berdasarkan variabel moderator. Penelitian ini menggunakan pendekatan meta-analisis comparison of group contrast terhadap 30 publikasi periode 2015–2025 yang memenuhi kriteria inklusi berbasis skema PICO. Data dianalisis menggunakan SPSS v29 untuk menghitung effect size keseluruhan dan subkelompok, disertai uji heterogenitas (I²) serta uji bias publikasi melalui Funnel Plot dan Egger Regression Test. Hasil analisis menunjukkan effect size keseluruhan sebesar 1,106 (kategori sangat besar), yang berarti model IMPROVE secara konsisten berdampak positif signifikan terhadap kemampuan matematis. Efektivitas tertinggi ditemukan pada kemampuan representasi matematis (ES=1,955, luar biasa) dan pemecahan masalah (ES=1,224, sangat besar), sementara berdasarkan jenjang pendidikan, pengaruh terbesar terjadi pada tingkat perguruan tinggi (ES=1,626, luar biasa). Tidak terdeteksi bias publikasi yang signifikan. Publikasi primer hanya diambil dari database Google Scholar, sehingga penelitian lanjutan disarankan memperluas sumber ke Scopus dan WoS. Model IMPROVE dapat diimplementasikan di berbagai jenjang pendidikan, dengan potensi tertinggi untuk meningkatkan representasi dan pemecahan masalah matematis, terutama di perguruan tinggi. Studi ini merupakan meta-analisis pertama yang secara khusus mengevaluasi model IMPROVE, memberikan bukti empiris kuat akan efektivitasnya lintas konteks dan jenjang pendidikan.

Abstract

The rapid advancement of technology poses challenges for educators to innovate in improving the quality of learning in the classroom. In addition, students grow up in an environment that is familiar with technology, so learning needs to be integrated with technology to suit their needs better. This research aims to develop interactive learning media assisted by Articulate Storyline on ratio material for seventh-grade students that meet the criteria of valid, practical, and effective. This research uses the Research and Development (R&D) research method with the ADDIE model (Analyze, Design, Develop, Implement, Evaluate). The results showed: (1) the learning media is categorized as very valid based on the results of material validation which reached a percentage of 91.25% and media validation of 93.75%, (2) the learning media is declared very practical because the response questionnaire of students and teachers reached a percentage of 88.89% and 83.33%, respectively, and (3) the learning media is in the medium or effective category because the N-gain test results show an average N-gain of 0.65. Thus, this interactive learning media of Articulate Storyline-assisted ratio can be declared valid, practical, and effective.

Abstract

TIMSS results show that Indonesian students’ math skills remain low compared to other countries. Due to the limited number of participants selected through sampling, many students are unfamiliar with TIMSS-style questions. Therefore, it is necessary to develop TIMSS-modeled math problems to help more students practice and become familiar with the question format. This research aims to develop TIMSS-model math problems using Banjar cultural ethnomathematics that are valid, reliable, and practical. The study used a Research and Development (R&D) method with the ADDIE development model. The test subjects were 30 eighth-grade students from SMP Negeri 15 Banjarmasin. Instruments included validation sheets, student response questionnaires, and test scores. Two experts validated the product, resulting in a logical validity score of 3.78, categorized as valid. Based on student performance, the questions were empirically valid and reliable. The practicality score from the student questionnaire was 4.475, categorized as practical. This research successfully produced five descriptive math problems that meet the validity, reliability, and practicality criteria.
