Abstract

Mostly, teaching materials merely focus on formulas and theories, yet there has not been found any teaching materials oriented to Qur'an. Due to that reason, it is significant to provide materials enabling students to learn independently, especially, those correlating the physics materials with Qur'an.  Therefore, this study aimed to produce students' worksheets of physics, known as LKPD, correlating Qur?an with Guided Inquiry to achieve the students? competencies, particularly, in the topic of equilibrium and rotational dynamics. This study employed the Research and Development design with the 4-D research model consisting of four stages, namely defining, designing, developing, and disseminating. This LKPD also contains six stages of Guided Inquiry, namely orientation, formulating problems, formulating hypotheses, collecting data, testing hypotheses, and formulating conclusions. Every stage of Guided Inquiry engages the Qur?an verses with the material. The findings showed the validity of LKPD was at 88% categorized as very valid. The questionnaires resulted 88% of teachers and 70.3% of students categorized as very practical and practical. The average post-test score for students? competence (82.45) is higher than the average pre-test score (49.64) and N-gain of 0.77 considered high and effective. In conclusion, the physics students' worksheet or LKPD which employed Guided Inquiry corresponding with Qur?an is considered valid, practical, and effective to promote students in learning physics.

Abstract

This research is motivated by the fact in the field that many students experience difficulties in basic physics lectures caused by learning methods, task difficulties, and inappropriate learning methods. Lecturers have difficulty providing an understanding of physics to students, because many students have misconceptions about physics from high school. Students are used to the physics learning style they brought from high school, such as relaxed learning, the teacher gives formulas instead of understanding physics concepts. As well as referring to one of the missions of the FTIK IAIN Batusangkar that lecturer activities must integrate the Al-Qur’an and hadith. The purpose of this research is to produce a basic physics Student Activity Sheet integrating the Al-Qur’an with scaffolding approach a valid and practical. This research is a type of development research with the ADDIE model. The research instruments used were validation sheets and student response questionnaire sheets. Based on the results of product are in the very valid category with a percentage of 84, 00%. Results from student and lecturer response questionnaires found that the student developed were practical with a percentage of 84, 81% and 75, 00% in the very practical category and practical category

Abstract

This study aimed to determine whether students who used the Self Organized Learning Environments (SOLE) learning model using the Microsoft Teams application had better learning outcomes than students who used the face-to-face learning model. The post-trial-only control group design is a study design used in quasi-experimental studies. The population of this study was XI IPA SMA Negeri 1 Bukittinggi. Two classes are sampled, that is, experimental class XI IPA 7 and control class XI IPA 6, which are sampled through normality test, homogeneity test and population mean similarity test. The sampling method uses simple random sampling where the results of the analysis found that both classes of samples are normally distributed, have homogeneous variants and the average population class is the same. The 20-question final exam is a tested and analyzed research tool. The experimental class achieved an average overall score of 80.13 for the cognitive domain, while the control class got an average final test score of 77.28. For the affective domain, the average value of the experimental class was 73.19, while the average value of the control class was 71.61. For the psychomotor domain, the average value of the experimental class was 73.51, while the average value of the control class was 70.04. The research hypothesis explains that "the learning outcomes of students who apply the SOLE (Self Organized Learning Environments) learning model assisted by the Microsoft Teams application are better than the learning outcomes of students who apply the direct learning model" formulated based on research results.

Abstract

The teaching materials used by teachers are still simple and limited methods, such as only using power points and printed books. The available teaching materials are not integrated with the Qur’an and are technology-based. One of the current technologies being developed is Augmented Reality (AR) which can transform images into 3 dimensions. AR can help visualize Solar System material so that it can attract students' attention. Therefore it is necessary to develop a Solar System module with an Augmented Problem-Based Learning Model. Reality (AR) integrated Qur’an. The type of development research used is the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The data collection technique used is quantitative data collection and quantitative data analysis techniques come from validation instruments. The module was validated in terms of media validation, material, and interpretation. The population of this study is class VII at MTsN 2 Kota Sawahlunto while the sample used is class VIIA. The sampling technique used is Probability Sampling.
