“…Previous research on reflective abstraction using the APOS mental structure indicated that females perform better than male students with a fair category, recommending further research to improve these results (Rahmawati et al, 2018). Many studies have analyzed reflective abstraction levels from secondary school to higher education levels (Sutrisna et al, 2021(Sutrisna et al, , 2022Widiyasari et al, 2020;Yusepa, 2017). Previous research focused solely on identifying and characterizing reflective abstraction skills rather than on teaching efforts using instructional materials to train reflective abstraction skills.…”

This research aims to produce a valid, practical, and effective cartoon concept teaching book based on a contextual approach for training students' reflective abstraction skills. This research method usesd research and development with the 4-D model, namely define, design, develop, and disseminate. Instruments used in this study include a validation sheet for the teaching book using the cartoon concept based on a contextual approach, a student response questionnaire, and pretest and posttest assessments of students' reflective abstraction skills. The descriptive-quantitative technique was used to analyze the research data. Data on product-developed validity and practicality were analyzed descriptively. In contrast, the product's effectiveness was analyzed descriptively using the n-gain formula and quantitatively using pretest-posttest control group design. The results of the study indicated that (1) the validity of the teaching book using the cartoon concept based on a contextual approach was valid (3.43) and reliable (85.71), (2) the practicality of the teaching book was considered practical with an average of 65.96, categorized as excellent, (3) statistical test results showed that the teaching book using the cartoon concept based on a contextual approach had a significant effect (sig. 2-tailed < 0.05) on students' reflective abstraction abilities. The average improvement in pretest and posttest reflective abstraction skills was indicated by the N-Gain value in the experimental group (0.58 - moderate) and the control group (0.25 - low). Students in the control class performed reflective abstraction up to the process stage, while students in the experimental class engaged in reflective abstraction up to the object stage. Thus, the teaching book using the cartoon concept based on a contextual approach is valid, practical, and effective in training students' reflective abstraction skills.

The elements, most students are wrong in determining the volume and surface area and almost all students are wrong in working on questions with the theme of flat-sided space shapes.…”

The purpose of this study was to improve students' mathematical concepts through improving communication skills and students' mathematical dispositions using Discovery Learning assisted by Cabri Express. This research is development research using the 4-D development model, which consists of the Define, Design, Develop, and Disseminate phases. The subjects in this study were 18 students. Data collection techniques in this study used the instrument questions given in the form of written tests, while the data analysis techniques in this study were data collection, data processing, data presentation, and concluding. So that the conclusions that can be drawn from this study are Cabri Express assisted teaching materials on flat plane material developed using three stages, namely define, design, and develop. Teaching materials have been validated with an average value of 87.3% with very valid and very practical criteria. Thus, the Cabri Express-assisted Discovery Learning teaching material on flat-sided spatial construction material is feasible to use. Furthermore, the teaching materials developed received a positive response from students with a percentage of 76% in the "interesting" category. Students' mathematical communication ability is 74% and students' mathematical disposition is 76% in the Good category. This proves that using teaching materials based on discovery learning assisted by Cabri Express improves students' communication skills and mathematical dispositions.
