Abstract

The purpose of this study is to develop and test the feasibility of android-based interactive learning media based on the feasibility of the validator's assessment from the material side and the media side. This type of research is R&D (research and development). The procedure used in this research and development is the procedure from Borg & Gall, which has been modified by the Puslitjaknov Team using three stages out of 5 stages, namely conducting a needs analysis to be developed developing initial products, and product validation and revision. The product of this research was assessed qualitatively, namely on a 5-point scale ranging from 1 to 5. So, the Likert scale was used for evaluation. This study resulted in an android-based interactive learning media that has been declared valid and feasible to be used as mathematics learning media by five validators from the material side who obtained an average score of 3.75 (good category) and five validators from the media side with a score an average of 3.64 (good category) with each maximum score of eligibility is 5. So, it can be concluded that the android-based interactive learning media developed is valid and feasible to be used as a mathematics learning media.

Abstract

One of skills needed in the disruption era is the mathematical connection ability. However, this ability has not been optimally facilitated through learning process. In fact, the disruption era also encourages renewal, one of which is through the provision of quality learning resources both in terms of content and approach. In addition, the disrupstion era has also led to various approaches that more suitable with existing developments and changes, such as the STEAM approach. Therefore, it is important to develop a qualified STEAM-based mathematics teaching material to improve students' mathematical connection abilities. The development of this teaching material uses a modified Borg and Gall model of research and development (R&D) method. There are ten stages that aim to develop and describe the quality of STEAM-based mathematics teaching materials in three indicators, namely validity (characteristics suitability and feasibility), practicality (readability), and effectiveness in improving students' mathematical connection abilities. The final results are STEAM-based mathematics teaching materials that are valid (meet the teaching materials characteristics suitability and include in the very feasible category with feasibility score of 89,09%), practical (easy to understand with readability score of 67.13%), and effective in improving students’ mathematical connection abilities with moderate improvement category (with gain normalization index score of 0.395).

Abstract

This research attempted to increase motivation and mathematics learning achievement in the sequences and series material. It was in the form of Classroom Action Research (CAR) and used Triastra method, a method which combines Problem Based Learning (PBL), interactive quiz, and structured tasks through the interactive quiz. Two cycles were done by the researcher starting from pre-cycle. Each cycle consisted of planning, implementation, observation, and reflection. 30 students, including 3 male students and 27 female students of the Class X Multimedia 2 of State Vocational High School 1 Kendal or SMK Negeri 1 Kendal in the academic year of 2019/2020 were involved. Their data were collected using test, observation, and questionnaire. To interpret the data, the researcher used descriptive analysis method. Findings showed that there was an increase in the motivation to the high category, namely from 74% in the cycle 1 to 87% in cycle II. In terms of learning achievement, it increased from 23% in the cycle 1 to 47% in cycle II, while the mean of the achievement increased from 5.95 in cycle 1 to 7.18 in cycle II. Thus, it is concluded that Triastra method can increase students’ motivation and mathematics learning achievement.

Abstract

Mathematical connection ability is one of the important abilities. The students' self-efficacy also needs to be considered. The purpose of this study was to determine the students' mathematical connection ability in REACT learning with the RME approach in terms of students' self-efficacy. This research uses mix method with a sequential explanatory design. The population in this study were eighth-grade students of Integrated Islamic Junior High School Nurul Islam Tengaran. The research instrument used was a test of mathematical connection ability and a self-efficacy questionnaire. The results of this study are (1) the mathematical connection ability of students with REACT learning using the RME approach achieves the criteria for learning mastery; (2) the average mathematical connection ability of students with REACT learning using the RME approach was better than students with expository learning; (3) there are differences in students' mathematical connection abilities in terms of students' self-efficacy levels in REACT learning with the RME approach; (4) Students with high self-efficacy fulfill the three indicators of mathematical connection ability. Students with medium self-efficacy are sufficient to meet the three indicators of mathematical connection ability but still need more practice. Students with low self-efficacy only fulfilled the second mathematical connection ability indicator.
