Abstract

Ikatan kimia merupakan materi yang sering menyebabkan miskonsepsi bagi siswa. Miskonsepsi ini menjadi salah satu penghambat dalam proses pembelajaran dan menghalangi pencapaian standar ketuntasan belajar minimal. Salah satu cara untuk meremediasi miskonsepsi adalah dengan menggunakan E-LKPD berbasis refutation text. Penelitian ini bertujuan untuk menghasilkan media pembelajaran E-LKPD berbasis refutation text. Penelitian ini menggunakan model Analyze, Design, Development, Implementation, Evaluation (ADDIE), yang dibatasi hingga tahap development. Instrumen yang digunakan dalam penelitian ini meliputi lembar penilaian kelayakan atau kevalidan dari ahli instrumen, materi, dan media, penilaian guru kimia SMA/sederajat, serta angket respon siswa SMA/sederajat. Produk E-LKPD disajikan dalam format digital melalui heyzine.com, yang dapat diakses melalui perangkat elektronik. Berdasarkan hasil penelitian, E-LKPD berbasis refutation text pada materi ikatan kimia memperoleh kategori "Sangat Baik" dan dapat diujicobakan dalam pembelajaran ikatan kimia.

Abstract

This research aimed to describe the validity or feasibility value of developing a game-based augmented reality learning application to introduce chemical laboratory equipment. The application developed was AR-LAB (Augmented Reality Laboratory), combining augmented reality technology with quizzes. This research employed development research using Richey and Klein's theory, which contains three steps: planning, production, and evaluation. The results show that the product's validity by material and media experts was 91.67% and 91.67%, respectively, in the very good category. The teacher assessment provided an average score of 112.4 from the ideal maximum score of 120, with an ideal level reaching 93.60% in the very good category. Meanwhile, testing by ten students obtained the maximum score in the very good category. The successfully developed media has the advantage of introducing laboratory equipment in three dimensions that are affordable and easy for students to learn about chemical laboratory equipment.

Abstract

Chemical misconceptions often occur when students need to understand the initial concept. This misconception has an impact on students' ability to understand the material and results in a decrease in students' learning achievement. Students' concept understanding can significantly improve by applying practical learning approaches, models, and strategies. This study aims to determine how applying the QODE learning model based on PjBL improves grade XI students' learning achievement and critical thinking skills on Buffer Solution topic. This type of research is a quasi-experiment with a nonequivalent control group pretest–posttest design. This study's subjects were control class for cooperative learning group investigation learning model and experimental class for PjBL-based QODE learning model at SMA Negeri 1 Sleman. Two intact classes (n = 36 per group) completed a two-tier multiple-choice critical-thinking test and an achievement test before and after a 3-session intervention. The research data were analyzed using the Wilcoxon and the N-gain tests. The Wilcoxon test result shows that both learning models used in experimental and control groups influence student learning achievement and critical thinking with the value of Sig. <0.05. N-Gain test shows that the experimental group experienced an increase of 0.74 for critical thinking skills and 0.78 for student learning achievement which in high category, while the control group experienced an increase of 0.38 for critical thinking skills and 0.73 for student learning achievement which in low and high category. These findings indicate that the QODE learning model based on PjBL contributes to improving students' critical thinking.

Abstract

This study aimed to compare the impact of science, technology, engineering, and mathematics (STEM) and contextual approaches on students' motivations for learning and achievements in chemistry lessons focused on acid-base materials. A quasiexperimental design with a non-equivalent control group was used, and the participants were 66 students of class XI Science students from State Senior High School 1 (SMA N 1) Kalibawang. Data collection instruments included pre and post-questionnaires and test questions. The findings revealed significant differences in students' learning motivations and achievements between the STEM and contextual approaches to acid-base materials. Both approaches improved students' learning motivations, with the STEM approach yielding higher gains.

Abstract

Students often experience difficulty learning chemistry because the concepts are abstract and complex and require deep understanding. Therefore, innovation in learning is needed. Educational media is crucial for fostering this innovation. This research aims to develop educational materials on Powtoon animation that utilize a scientific approach to instruct on electrolyte and non-electrolyte solutions and evaluate their efficacy. The method applied was ADDIE model covering five steps, i.e. Analysis, Design, Development, Implementation, and Evaluation. The study involved three peer reviewers, experts in media and materials, five high school chemistry teachers, and thirteen students. Data were collected through questionnaires that were analyzed qualitatively and quantitatively with validated instruments. The result is an interactive learning video in HD mp4 format covering electrolyte and non-electrolyte solutions. The product obtained a score of 82.5% and 95% by material and media experts, respectively, and was categorized as valid. Assessments by teachers and students show scores of 82,5% and 94.4% in a very good category. This Powtoon animation video serves as an alternative and potential medium for teaching chemistry on this topic in the classroom.
