Abstract

This research was motivated by the mathematics learning results of class IX students at Angkasa Kupang Middle School, especially in the material of congruence and congruence which were still low. The aim of this research is to improve the learning outcomes of class IX students at SMP Angkasa Kupang on congruency and congruence material. The type of research used is Classroom Action Research (PTK) which refers to the Kemmis & Mc Taggart model, which is carried out in 2 cycles with each cycle consisting of 4 stages, namely: 1) Planning; 2) Implementation; 3) Observation; and 4) Reflection. The data collection techniques in this research are observation and tests, while the data analysis is descriptive qualitative and quantitative. The results of this research show that the learning outcomes in cycle I were 55,55%, increasing to 81,48% in cycle II, the value of implementing observations of teacher teaching activities in cycle I was 93,17% increasing to 100% in cycle II and the value of implementing activities students in cycle I was 76,92%, increasing to 96,15% in cycle II. Thus, it can be concluded that the application of the problem based learning model assisted by interactive e-books can improve the learning outcomes of class IX students at SMP Angkasa Kupang on congruence and congruence material. Keywords: interactive e-book, learning outcomes, problem based learning, similarity and congruence

Abstract

This research aims to determine the learning design for adding and subtracting integers using realistic mathematics in the context of congklak (Indonesian Traditional Game ) at SD Inpres Nunbaun Delha. The method used in this research is design research, focused on developing learning designs in the form of hypothetical learning trajectories. This is a qualitative research involving 6 students in the pilot experiment cycle and 24 students in the teching experiment cycle. The data collection techniques used were tests, field notes, interviews and documentation. Meanwhile, data analysis techniques were carried out qualitatively. Thi sresearch produces a learning design using the PMRI approach. The resulting learning design consists of 7 activities where the PMRI approachis the main reference in each activity. The contextused in this researchis the traditional game congklak. Students were asked to play the traditional game congklak. After that, students observed the process of playing the traditional game congklak. Students were given congklak which had been modified to play. Then students solve the problems by playing congklak which has been modified in the way they play. Next, students draw circles to solve problems involving adding and subtracting integers. After that, students solve problems without using congklak or pictures of circles and end with students concluding the concept of adding and subtracting integers.

The method used in this research is the Research and Development method using the ADDIE model. The data collection techniques and instruments used were interviews, questionnaires, and tests. The data analysis techniques used are qualitative and quantitative descriptive analysis techniques. The research results show that Android-based learning media on the triangle and quadrilateral material meets the criteria of being valid, practical, and effective. The results of the feasibility of learning media were obtained from the assessment of 3 material and media experts with an average validity of 4.61 and included in the "valid" category. For the practical aspect, the response with average response result was 4.3, the response from small class students was 4.48, and the large class was 4.52 so it was included in the "practical" category. For the effectiveness criteria, the percentage of learning completeness results for small classes was 80% and for large classes, the class completion results were 86.95% so the learning media was categorized as "effective". Thus, the learning media developed is valid, practical, and effective

Abstract

The number of smartphone users is increasing across various demographics, including students. With the presence of smartphones among students, it should be able to assist learners in enhancing their interest and understanding of mathematics effectively, anytime and anywhere. Therefore, this research aims to develop a mathematics learning media based on an Android application using PowerPoint and iSpring for set theory material for Grade VII students at Swadaya Tarus Private Junior High School that is valid, practical, and effective. The method employed in this research is research and development using the ADDIE development model: Analysis, Design, Development, Implementation, and Evaluation. Data for this research were obtained through interviews, questionnaires, and tests. The results of this research show that the set theory class application meets the criteria for valid, practical, and effective learning media for set theory material. The average total validity score from three validators is 4.34, indicating that the Android-based mathematics learning media falls into the valid category. The average practicality score from the large class teacher is 4.38, and the responses from the small-scale trial students were 4.6, while the responses from the large-scale trial students were 4.67, placing the Android-based mathematics learning media in the practical category. Additionally, the pass rate for small-scale trial students was 80%, and the pass rate for the large-scale trial students was 70%, indicating that the developed Android-based mathematics learning media falls into the effective category.

Abstract

This research aims to explore the differences among self regulating learning aspect of math education students-FKIP Undana involving three groups of students which are the first level (the first semester), second level (fifth semester) and third level (ninth semesters) students to review the ability of the individual. The samples included 167 students that consist of 60 students of the first level (18 with high ability; 27 with average ability and 15 with low ability), 64 students of the second level (16 with high ability, 30 with average ability and 18 with low ability) and 43 students of the third level (6 with high ability, 24 with average ability and 13 with low ability). This research is a survey research. The data collection is done by distributing questionnaires on self-regulated learning to those three groups. SRL questionnaire consists of 10 aspects, goal setting, motivation, learning difficulties analysis, self-efficacy, election strategies, meta cognition, resource management, performance evaluation, evaluation of the understanding, and self-satisfaction. Two-way ANOVA was utilized in the data analysis of this study. The results of the analysis showed that, the first level group is more excellent in SRL than two other levels. In a review of capabilities, the average comparison of all three groups showed that the average-ability students excel both the high and low-ability students in SRL.

Abstract

The purpose of this study is to explore pre-service mathematics teachers' conception of higher-order thinking in Bloom's Taxonomy, to explore pre-service mathematics teachers' ability in categorizing six cognitive levels of Bloom's Taxonomy as lower-order thinking and higher-order thinking, and pre-service mathematics teachers' ability in identifying some questionable items as lower-order and higher-order thinking. The higher-order thinking is the type of non-algorithm thinking which include analytical, evaluative and creative thinking that involves metacognition. This research is a descriptive quantitative research. The data were analyzed and visualized by percentages and diagrams. The participants are 50 Third-Year Students of Mathematics Education Department at Universitas Nusa Cendana. The results showed: (1) pre-service mathematics teachers' conception of lower-order and higher-order thinking more emphasis on the different between the easy and difficult problem, calculation problem and verification problem, conceptual and contextual, and elementary and high-level problem; (2) pre-service mathematics teachers categorized six cognitive levels at the lower-order and higher-order thinking level correctly except at the applying level, preservice mathematics teachers placed it at the higher-order thinking level; (3) pre-service mathematics teacher tend to made the wrong identification of the test questions that were included in the lower-order and higher-order thinking. One of the recommendations is pre-service mathematics teachers should be familiarized of higher-order thinking questions start from their first-year of study in University.
