As for teacher activity in cycle I with a percentage of 55% and in cycle II it reached 81%. Thus the GI-type cooperative model can be used in SPLDV materials.

Grades 7–12 teachers' perception of computational thinking for mathematics and technology

IntroductionAn ongoing trend on a global scale is the integration of computer science and programming in K-12 education. The integration has been motivated by the needs of the present and future labor market but also by the assumption that skills related to computer science and programming are valuable for citizens to navigate an increasingly digitalized society. Computational thinking (CT) is a concept that aims to define and summarize skills associated with programming and computer science and has received wide recognition within research and education. But how do the teachers perceive this concept, and how do they relate it to their own teaching and learning activities? This study aims to investigate and discuss teachers' perceptions of CT in grades 7–12 mathematics and technology.MethodsData have been collected from essay assignments in three instances of a professional development course on fundamental programming for grades 7–12 teachers in mathematics and technology. In the essays, the teachers reflect on CT in relation to mathematics and technology and teaching and learning activities in these subjects. With a theoretical framework for CT, the collected data have been analyzed with a directed content analysis approach to identify categories of interests for CT in relation to grades 7–12 mathematics and technology.ResultsThe results of the study show that the teachers perceive both opportunities and challenges in applying the CT concept in their teaching and learning activities. For example, it can strengthen the subjects through new practices and reinforce old practices, but it could be too complex and perceived as difficult by some students. Furthermore, many of the teachers perceive CT not only to be relevant for mathematics and technology but also for learning in general.DiscussionThe conclusion of the study is that CT has the potential to enhance teaching and learning activities in mathematics, technology, and other STEM subjects. If this should be successful, CT must not be involved too abstractly or too superficially. This study contributes to the discussion on CT in K-12 education, adding the teachers' perspective. The findings of this study can be used by teachers and other stakeholders in the design of classroom activities that apply the CT concept.

EFEKTIVITAS PEMBELAJARAN MATEMATIKA MELALUI PENDEKATAN CONTEXTUAL TEACHING AND LEARNING (CTL) PADA SISWA KELAS VII SMP ISLAM TERPADU AL HIKMAH KABUPATEN PANGKEP

This research is a pre-experimental study involving an experimental class which aims to determine the effectiveness of learning through the Contextual Teaching and Learning (CTL) Approach in learning mathematics in class VII students of Al Hikmah Integrated Islamic Middle School, Pangkep Regency, 2021/2022 academic year. While the effectiveness of learning is viewed from three aspects, namely: the implementation of learning, classical learning completeness, student activity, and student responses. A learning is said to be effective if at least three of the four aspects above are met, provided that aspects of student activity and classical learning mastery are met. Student scores after learning mathematics through the application of the Contextual Teaching and Learning approach have achieved classical mastery. The average positive student activity is 85.7% and 12.5% negative, this indicates that student activity in learning mathematics through the Contextual Teaching and Learning approach can be said to be active. Student responses to learning the Contextual Teaching and Learning approach can be said to be in accordance with the standards set, namely exceeding 75% of students who gave a positive response. Based on the results of descriptive and inferential analysis, it shows that student learning outcomes before learning the Contextual Teaching and Learning approach are smaller than student learning outcomes after learning the Contextual Teaching and Learning approach, thus learning mathematics through the Contextual Teaching and Learning approach is effectively used on the subject of Algebra in class students VII Al Hikmah Integrated Islamic Middle School, Pangkep Regency.

The Benefit of Using a Psychoeducation Program Integrated with Quranic Values to Mathematics Anxiety Among Students

An innovative approach to education should be provided in Mathematics learning activities to battle anxiety. However, studies on handling mathematical anxiety problems through psychoeducational programs have not been conducted. This study aims to analyze the benefits of implementing a psychoeducational program that integrates Qur’anic values on students’ mathematics anxiety. The quasi-experimental research was applied to junior high schools in Indonesia, consisting of experimental and control groups. Furthermore, the mathematical anxiety scale was used as a data collection technique, while the Kruskal-Wallis Test was used for analysis. The results showed that the application of psychoeducational programs is beneficial in reducing students’ mathematics anxiety levels. Therefore, psychoeducation programs integrated with Quranic values are recommended for mathematics learning activities. The application is suitable for various groups of students. However, initial training is needed for teachers to have a level of mastery of scientific integration (Islam), hence the application of the programs can run well.

Based on the results of this study, students have met the criteria for the effectiveness of learning mathematics, so it can be concluded that learning mathematics is effectively implemented through the application of the Numbered Head Together (NHT) cooperative model in class IX-G students of SMP Negeri 21 Makassar.

Localized Game-Based Learning Activity Sheets in Mathematics 7

To become a critical thinker and problem solver, learners need the mastery of the basic competencies. To ensure that meaningful learning occurs in a mathematics classroom, learning resources reflecting their context must be readily available. Unfortunately, there has been a dearth of localized materials for the Ilocano learners. Hence, this study developed Localized Game-Based Learning Activities (LGBLAs) in Mathematics 7 based on the teachers’ perceived level of mastery of the learners along with the Most Essential Learning Competencies (MELCs) in Number and Number Sense, Algebra, Geometry, and Statistics and Probability. Following the research and development (R and D) framework, data were gathered using a survey rating scale from the 66 Mathematics 7 teachers in the Schools Division of Ilocos Norte. Means with their equivalent descriptive interpretations were utilized to analyze and interpret the data. The results showed that learners exhibited nearly mastery in some of the learning competencies in Mathematics 7. This could mean that they have not sufficiently acquired the fundamental skills required to move to more advanced mathematical learning tasks. However, the key concepts and skills could be enriched by supplementing instruction with appropriate, contextualized, and relevant curriculum support materials. Hence, LGBLAs in Mathematics 7 was developed. The LGBLAs was found to be very highly valid and very highly acceptable as a curriculum support material for mathematics instruction as evaluated by the content experts and the key teachers in Mathematics 7. It is then recommended that LGBLAs be adopted for classroom use to improve the mastery level of learners in the different learning competencies along with Number and Number Sense, Algebra, Geometry, and Statistics and Probability.

PENGARUH MINAT TERHADAP AKTIVITAS BELAJAR SISWA KELAS VIII PADA MATA PELAJARAN MATEMATIKA DI SMP KRISTEN ENDE
