Abstract

All aspects of life, including the education system, have undergone many changes due to the Covid-19 pandemic. We need media that can facilitate and attract students to carry out learning activities. This study aims to develop GeoGebra-based mathematics learning media. The method used in this research is Research and Development (R&D) with the ADDIE model (Analysis, Design, Develop, Implement, and Evaluate). The research was carried out at UIN Sayyid Ali Rahmatullah Mathematics Study Program in semester 3. The research subjects for the small-scale field test were class A, which had 32 students; for the large-scale field test, there were 132 students in Mathematics Education 3rd Semester. The results of research on the development of GeoGebra-based learning media in the Flat Analytical Geometry course for students majoring in Mathematics Education at UIN Sayyid Ali Rahmatullah Tulungagung were declared valid, practical and effective. The future hope for developing similar media is to expand the scope of the material discussed because the media developed is limited to flat analytic geometry operations.

Abstract

The purpose of this research to produce Creative Problem Solving (CPS)-based LKPD that meet the criteria of validity, practicality and effectiveness to improve critical thinking skills in quadrilateral and triangle material. The research type is Research and Development (R&D) ADDIE model which Analysis, Design, Development, Implementation and Evaluation. Data collection techniques use observation, interviews, questionnaires and tests. The product test subjects were class VIII students at SMP Negeri 1 Patianrowo and SMP Negeri 2 Patianrowo. The results of the research according to expert assessment show that the teaching materials developed have valid criteria. This means that the teaching materials developed are suitable for use by students. The assessment based on the results of teacher and student response tests shows that the teaching materials developed meet the criteria of being very practical. This means that the teaching materials developed can be implemented in the mathematics learning process, especially in quadrilaterals and triangles. The posttest results show that there is a significant difference in critical thinking abilities between the control class and the experimental class. This means that the teaching materials developed have an effect on increasing students' critical thinking skills with the percentage of increase being at a very high effect, namely 80.2%. Based on this assessment, it can be concluded that the teaching materials developed have met the criteria for validity, practicality and effectiveness in improving critical thinking skills of student in quadrilateral and triangular material

Abstract

This research aims to: 1) determine the process of developing teaching module, 2) determine the validity of teaching modules, 3) determine the practicality of teaching modules, and 4) determine the effectiveness of teaching modules. In general, the development of this CLT-based teaching module is to find out whether the taching module can minimize students’ mathematical anxiety.The research follows a development model, specifically the Plomp development model which consists of 5 phase, 1) preliminary phase, 2) design phase, 3) realization phase, 4) test, evaluation and revision phase, 5) implementation phase. The developed teaching module focuses on trigonometry material for phase E students at MAN Se-Tulungagung. Data collection methods include validation, objective observation, and questionnaires. Practicality data were obtained from teacher questionnaires, while effectiveness data were derived from students’ mathematical anxiety questionnaires. Based on data analysis, the following results were obtained: 1.) The validation score for the teaching module was 3.754, categorizing it as valid. 2.) The practicality score for the teaching module was 4.02, indicating high practicality. 3.) The teaching module effectively minimized mathematical anxiety, as evidenced by anxiety levels in experimental classes compared to control classes. Control classes using conventional learning showed higher anxiety levels, with MAN 3 Tulungagung at 2,89 (‘anxious’), MAN 2 Tulungagung at 2.615 (‘anxious’), and MAN 1 Tulungagung at 2.204 (‘anxious’). Meanwhile, experimental classes, after using the teaching module, showed lower anxiety levels: MAN 3 Tulungagung at 1.98 (‘moderate anxiety’), MAN 2 Tulungagung at 1.96 (‘moderate anxiety’), and MAN 1 Tulungagung at 1.44 (‘moderate anxiety’)
