Abstract

Chemistry learning often presents challenges in the form of misconceptions, particularly concerning buffer solutions. This material is abstract as it involves the concepts of chemical equilibrium and acid-base properties. This study aims to provide information on using diagnostic tests with the interview-about-event method to explore students' mental models. The research employed a descriptive qualitative method with nine 12th-grade students from a high school in Makassar City. Data was collected through in-depth interviews that asked students to explain given phenomena, utilizing research instruments in the form of a four-tier diagnostic test and semi-structured interviews. The answers of each student were mapped to obtain a profile of their mental models. The results indicated that students' mental models revealed diversity in their responses, especially at the submicroscopic level. Their mental models tended to be simple, incomplete, and macroscopic, characterized by misconceptions such as considering equilibrium shifts to be separate from the direct reactions of buffer components, misunderstandings in using arrows for partial and complete ionization, incorrect definitions of acids, and misconceptions about buffer solutions neutralizing pH or causing pH changes. The diversity and consistency of these misconceptions underscore the importance of a pedagogical approach focused on deep conceptual understanding and the integration of multiple levels of chemical representation.

Abstract

Science process skills (SPS) are a key component of chemistry learning under the Kurikulum Merdeka, yet classroom assessment in chemistry still emphasizes knowledge over skills, and systematically designed SPS test instruments remain limited particularly for the reaction rate topic, which is closely tied to scientific inquiry activities. This gap is widened by the limited integration of expert validation with empirical Rasch Model analysis in developing SPS instruments for this topic, making the development of a valid, practical, and reliable instrument an important undertaking. This study is a development research project aimed at producing a valid, practical, and reliable Science Process Skills (SPS) test instrument covering the topic of reaction rates. The instrument was developed using the Plomp model, which comprises the preliminary investigation, design, realization/construction, test/evaluation/revision, and implementation phases. The developed instrument consists of multiple-choice questions with five answer options covering science process skill indicators. Field testing was conducted with students from class XI MK 1 at SMA Negeri 10 Gowa. Data were collected via expert validation sheets, teacher and student response questionnaires, and student test results. Data analysis was performed using descriptive methods and the Rasch Model. The results indicate that the developed SPS test instrument was confirmed valid based on expert judgment, reliable based on both theoretical and empirical consistency analyses, and practical based on highly positive teacher responses regarding its ease of use. Consequently, the developed SPS test instrument for the reaction rate topic satisfies the requirements for validity, reliability, and practicality, making it suitable for measuring students' science process skills. ABSTRAK Keterampilan proses sains (KPS) merupakan aspek penting dalam pembelajaran kimia pada Kurikulum Merdeka, namun penilaian pembelajaran kimia di sekolah masih lebih menitikberatkan pada aspek pengetahuan, sementara instrumen tes yang secara sistematis mengukur KPS masih terbatas, khususnya pada materi laju reaksi yang sarat aktivitas ilmiah. Kesenjangan ini diperbesar oleh belum terintegrasinya validasi ahli dengan analisis empiris berbasis Model Rasch pada pengembangan instrumen KPS materi tersebut, sehingga pengembangan instrumen yang valid, praktis, dan reliabel menjadi penting untuk dilakukan. Penelitian ini merupakan penelitian pengembangan yang bertujuan menghasilkan instrumen tes keterampilan proses sains (KPS) pada materi laju reaksi yang valid, praktis, dan reliabel. Pengembangan instrumen menggunakan model Plomp yang meliputi fase investigasi awal, fase desain, fase realisasi atau konstruksi, fase tes, evaluasi dan revisi, serta fase implementasi. Instrumen yang dikembangkan berupa butir soal pilihan ganda dengan lima alternatif jawaban yang meliputi indikator keterampilan proses sains. Uji coba dilakukan pada peserta didik kelas XI MK 1 SMA Negeri 10 Gowa. Data penelitian diperoleh melalui lembar validasi ahli, angket respons guru dan peserta didik, serta hasil tes peserta didik. Analisis data dilakukan secara deskriptif dan menggunakan Model Rasch. Hasil penelitian menunjukkan bahwa instrumen tes keterampilan proses sains yang dikembangkan dinyatakan valid berdasarkan penilaian ahli, reliabel berdasarkan analisis konsistensi teoretis maupun empiris, serta praktis berdasarkan respons guru yang sangat positif terhadap kemudahan penggunaannya. Dengan demikian, instrumen tes keterampilan proses sains pada materi laju reaksi yang telah dikembangkan telah memenuhi aspek kevalidan, reliabilitas, dan kepraktisan yang layak digunakan sebagai alat ukur keterampilan proses sains peserta didik.

Abstract

Low understanding of simple machine concepts and diverse cognitive readiness among students often limit the effectiveness of standard science instruction. This classroom action research investigated the implementation of Teaching at the Right Level (TaRL) to improve science learning outcomes among Grade VIII students at SMP Negeri 3 Makassar. The study followed the Kemmis and McTaggart model across three cycles involving 48 students. Data were collected using validated learning-outcome tests, classroom observation sheets, and student-response questionnaires, then analyzed descriptively using quantitative percentages and qualitative thematic reflection. The intervention evolved systematically: Cycle I utilized initial heterogeneous grouping; Cycle II shifted to small homogeneous grouping based on cognitive readiness with targeted scaffolding; and Cycle III further reduced group sizes alongside integrated practical hands-on activities. Classical mastery increased from 33.3% in Cycle I to 89.6% in Cycle II and 97.9% in Cycle III, accompanied by an increase in mean scores from 65.33 to 89.58 and 94.00. Within the scope of this action research, these iterative refinements particularly aligning group homogeneity, scaffolding, and practical tasks with student readiness were associated with improved student participation and learning outcomes across cognitive levels.

Abstract

This classroom action research aimed to improve the collaboration skills of Grade IX students at SMP Negeri 3 Makassar in science learning on environmental issues, specifically the energy and food crisis sub-topics, through the Gallery Walk method integrated within a Problem-Based Learning sequence. The study was conducted in two cycles, each comprising planning, action, observation, and reflection stages, involving 36 Grade IX students. Collaboration skills were assessed through an observation rubric covering six indicators (effective communication, active participation, shared responsibility, respect for peers' opinions, cooperation in completing tasks, and conflict management), while a separate student-response questionnaire measured perceptions of the Gallery Walk method. The average collaboration skills score increased from 15.75 (65.6%, Skilled category) in Cycle I to 23.25 (96.9%, Very Skilled category) in Cycle II, following refinements that clarified role division, provided gallery-visit assessment guidelines, and reinforced student motivation. All students (100%) reported strong agreement across the response-questionnaire items, indicating positive perceptions of the method; this result reflects perception rather than a measure of collaboration-skill achievement and should not be treated as additional evidence of effectiveness. Given the single-group, two-cycle design without a comparison condition, the findings indicate a substantial increase in observed collaboration skills across cycles following the Gallery Walk-based intervention, rather than a definitively proven causal effect.
