Abstract

The transformative activity was crucial for problem-solving. In resolving problems, cognitive conflicts could arise, characterized by construction errors marked by deviations or differences from scientific concepts. Eight of the 106 students who experienced cognitive conflicts made construction errors in transformative activities. These errors were categorized into four groups. This research aimed to describe students' construction errors in transformative activities when solving problems that might lead to cognitive conflicts. The research design was phenomenological, with four subjects selected and one student from each group. Student responses and interview results served as research data, analyzed through narrative text analysis. The research findings revealed four forms of construction errors in students during transformative activities in problem-solving that might lead to cognitive conflicts: (1) pseudo construction "correct," occurring when students provide a correct answer to a problem, but upon closer examination, it was found that the clarification of the answer was incorrect; (2) pseudo construction "incorrect," happening when students gave an incorrect answer to a problem, but upon closer examination, the students had a correct thought process and could provide the right answer; (3) hole construction errors, occurring when there were inconsistencies in the construction process of concepts in students' minds; and (4) mis-analogical construction errors, occurring when students made errors in analogizing a problem with representations of other concepts. These four construction errors occurred in transformative activities based on incomplete rule-based systems. Examining these construction errors allowed instructors to improve students' transformative thinking activities according to linear equations with one variable.Aktivitas transformasional sangat penting dalam menyelesaikan masalah. Dalam penyelesaian masalah kemungkinan terjadi konflik kognitif, yaitu kesalahan konstruksi yang ditandai ada penyimpangan atau perbedaan dengan konsep ilmiah. Mahasiswa mengalami konflik kognitif sebanyak 106 orang dan 8 mahasiswanya telah melakukan kesalahan konstruksi dalam aktivitas transformasional. Penelitian ini bertujuan untuk mendeskripsikan kesalahan konstruksi mahasiswa dalam aktivitas transformasional menyelesaikan masalah yang memungkinkan terjadi  konflik kognitif. Jenis penelitian ini adalah fenomenologi dengan dipilih 4 subjek penelitian yang masing-masing 1 mahasiswa dari setiap kelompok tersebut. Jawaban mahasiswa dan hasil wawancara digunakan sebagai data penelitian. Data penelitian dianalisis melalui analisis teks naratif. Temuan penelitian diperoleh bahwa ada empat bentuk kesalahan konstruksi mahasiswa yang dibedah dalam aktivitas transformasional menyelesaikan masalah yang memungkinkan terjadi konflik kognitif, yaitu (1) pseudo construction “benar” yang terjadi saat mahasiswa memberikan jawaban benar terhadap suatu permasalahan, namun ketika ditelusuri, ternyata mahasiswa salah dalam memberikan klarifikasi jawaban; (2) Kesalahan pseudo construction “salah” yang terjadi saat mahasiswa memberikan jawaban salah terhadap suatu permasalahan, namun ketika ditelusuri mahasiswa mempunyai cara berpikir yang benar dan dapat memberikan jawaban yang benar; (3)Kesalahan lubang konstruksi (hole construction) yang terjadi saat proses konstruksi konsep dalam pikiran mahasiswa ada yang tidak sesuai;  dan (4) kesalahan mis-analogical construction yang terjadi saat mahasiswa membuat kesalahan dalam menganalogikan masalah dengan representasi konsep lain. Keempat kesalahan konstruksi tersebut terjadi pada aktivitas transformasional berbasis aturan tidak lengkap (incomplete rule-based). Penelaahan kesalahan konstruksi ini dijadikan dasar bagi dosen untuk memperbaiki aktivitas berpikir transformasional mahasiswa sesuai konsep persamaan linier satu variabel

Abstract

This research aims to develop Canva-based interactive learning media to improve students' understanding of concepts in statistics materials at the MTs level. The research method used is Research and Development (R&D) by adapting the ADDIE (Analysis, Design, Development, Implementation, Evaluation) development model). The research subjects consisted of MTs grade IX students who participated in a small trial of 5 students and a large trial of 20 students. Data collection instruments include expert validation sheets, student response questionnaires, interviews, and pretest and posttest questions to measure understanding of concepts. The validation results showed media feasibility with a score of 84% (material experts) and 86% (media experts), so it was categorized as very good. The results of the small trial test with N-Gain obtained an average result of 0.90 in the high category and the results of the large trial test with N-Gain obtained an average result of 0.81 with the high category, The results of the response questionnaire in the small trial were 95.4% of the very good category. The results of a large trial test with an N-Gain of 0.81 in the high category, It can be concluded that Canva-based interactive learning media is effective and very feasible in improving students' understanding of concepts in statistical material.

Abstract

This research aimed to describe the characteristics of the transformational activities of Indonesian students in resolving problems based on cognitive conflict. The research employed a phenomenological approach with five students as subjects. The research instruments included tests and interview guidelines, and the analysis was conducted using the constant comparative method. Change-based activities are a good way to solve cognitive conflict issues, including full rule-based unexpected results, full rule-based matching problem parts, incomplete rule-based unexpected results, and incomplete rule-based matching problem parts. Exploring these characteristics serves as a foundation for instructors to enhance the quality of instructional design. Practically, a profound understanding of these characteristics can provide a solid foundation for educators to enhance their instructional design quality. By exploring and comprehending how students address cognitive conflict, instructors can design more effective learning experiences that align with the student's needs.

Abstract

The main objective of this study was to determine how the Concept Attainment learning model affects students’ creative thinking ability in learning three-dimensional geometry in Grade V at SDN 3 Geureudong Pase. This research employed a quantitative approach using a quasi-experimental method with a nonequivalent control group design. The participants consisted of 42 students, with 21 students from class V-A and 21 students from class V-B. Purposive sampling was used to select the sample. The research instrument was an essay test. Using SPSS 25, the results showed that both the experimental and control groups obtained a Sig. (2-tailed) value of 0.249 > 0.05, indicating that the Concept Attainment learning model has an effect on students’ creative thinking ability. Furthermore, the basic linear regression test revealed an R Square value of 0.348, indicating that the independent variable Concept Attainment learning model influenced the dependent variable (creative thinking ability) by 34.8%. Given that the significance value obtained was 0.005 < 0.05, it can be concluded that the Concept Attainment learning model significantly affects students’ creative thinking ability in learning three-dimensional geometry for Grade V at SDN 3 Geureudong Pase.
