Pengaruh Penggunaan Model Pembelajaran Guided Inquiry terhadap Minat Belajar Siswa Kelas VIII SMP Negeri 1 Toari

Deti Sri Rahayu — 2023-12-30

This research aims to investigate the impact of implementing the Guided Inquiry learning model on the level of students' interest in learning in the eighth grade of SMP Negeri 1 Toari. This study uses a quantitative method with a quasi-experimental approach. Two classes were selected as the experimental and control groups, with sample selection using a random sampling technique. Data were collected through questionnaires distributed to students. Data analysis was conducted to test the proposed hypotheses. Before hypothesis testing was performed, prerequisite tests, such as the normality test, were conducted to ensure that the data were normally distributed. The test results indicated that the data met the normality assumption. Homogeneity testing was also conducted, and the results showed that both groups had homogeneous variances. Subsequently, a paired sample t-test was conducted to examine the significance of the impact of the Guided Inquiry learning model on the interest in learning of eighth-grade students at SMP Negeri 1 Toari. The results of the analysis showed a significant impact of implementing the Guided Inquiry learning model on students' interest in learning.

Pengembangan Video Pembelajaran Matematika untuk Melatih Kemampuan Analisis Siswa Pada Materi Dimensi Tiga

Sanika Nur Afni — 2023-12-30

This study aims to develop mathematics learning videos to train students' analytical skills in three-dimensional materials that are valid, practical, and have potential effects. The development of these learning videos employs the ADDIE research method, which consists of five stages: Analysis, Design, Development, Implementation, and Evaluation. Research data were obtained through validation questionnaires, student response questionnaires, and student learning outcome tests. The trial subjects were 12th-grade science students at SMA Negeri 7 Palembang, South Sumatra. Based on the analysis of data obtained from expert validation, the mathematics learning videos to train students' analytical skills in three-dimensional materials were deemed "highly valid," with an average percentage of 91.77%. The practicality test resulted in a rating of "highly practical," with an average rate of 88.5%. Meanwhile, the potential effects aspect was deemed to have "potential effects" with an average percentage of 90% based on student learning outcome tests.

Analisis Self-Efficacy Siswa Sekolah Menengah Atas (SMA) dalam Pembelajaran Matematika di Masa Pandemi Covid-19

Reza Mulyadi — 2023-12-30

The COVID-19 pandemic is an epidemic that has brought major changes to all aspects, including educational aspects. Different learning methods will affect several students' affective abilities, one of which is self-efficacy. The importance of this ability attracted researchers to conduct research aimed at describing aspects of students' self-efficacy in learning mathematics. The approach used is a quantitative approach, with the type of research being survey research. The population in this study were all class XI students in one of the state high schools in North Aceh Regency, with the sample being students in classes XI MIA 1, XI MIA 2, XI MIA 4, XI MIA 5, and XI IIS. The instrument used is a questionnaire. Data analysis was carried out descriptively, namely explaining students' self-efficacy abilities and determining students' self-efficacy categories using hypothetical mean categorization. The research results showed that 87.85% of students had self-efficacy in the medium category. This indicates that the majority of students keep trying and do not give up quickly on studying mathematics during COVID-19.

Pengembangan Modul Matematika Berbasis Pendekatan Kontekstual Pada Materi Kubus dan Balok Kelas VIII Sekolah Menengah Pertama (SMP)

Dinila Sutri — 2023-12-30

This research aims to produce a contextual approach-based mathematics module on cubes and rectangular prisms for 8th-grade junior high school students. The type of research used is Research and Development (R&D) with a modified 4-D research model into 3-D, namely Analysis, Design, and Development. The instruments used in this research are validation and practicality questionnaires. The results of the development of mathematics learning modules have been validated by three validators, with the overall average assessment aspects such as didactic aspects, content, language, and appearance reaching 3.60 with a criterion of very valid. Furthermore, the practicality of the modules is assessed based on trial and evaluation using teacher response questionnaires, with the average practicality score of the contextual-based mathematics module reaching 94% and the student response questionnaire reaching 84.25%, both categorized as very practical. Therefore, this mathematics learning module has been proven to be very valid and highly practical.

Pengembangan E-Modul Berbasis Contextual Teaching and Learning (CTL) Pada Pokok Bahasan Persamaan dan Pertidaksamaan Linear Satu Variabel

Deti Anggraini — 2023-12-30

This study aims to produce an e-module product based on Contextual Teaching and Learning (CTL) on the subject of valid, practical, and effective single-variable linear equations and inequalities. This research is a type of research and development using the ADDIE model, namely analysis, design, development, implementation, evaluation. The object of research is the quality of e-module based on Contextual Teaching and Learning (CTL) on the subject of linear one-variable equations and inequalities. Data collection techniques in this study were observation, questionnaires, and tests. The data analysis techniques in this study were validity, practicality, and effectiveness. The results of this study were obtained from aspects of validity, aspects of practicality and aspects of effectiveness. a) the validity aspect obtained valid criteria based on the evaluation of material experts with a total average score of 3.4; media expert with an average score of 3.7; educators with an average score of 3.5 and practicality aspects obtained practical criteria based on student response questionnaires with an average score of 3.2 and the observation results of 82.5%; b) effectiveness aspects with high criteria based on student learning outcomes tests with a percentage of 75.00%.
