Abstract

This study aims to determine the effectiveness of of physics-based learning lesson study with multirepresentation on Basic Physics course I. The subjects of the study are the first level students as much as 42 people divided into 2 classes, namely experimental and control class. The data completion instrument is a skill test consisting of 5 items about the essay. Data analysis is descriptive analysis to see the picture of result learn student process skill by using absorption criterion, learning efficiency, and mastery learning at presenter and postest. The data analysis showed that the average absorption rate of the class was 9.28% with the less favorable category in pretest experimental class at posttest 17.78% less good and 9,30% with less good category for control class at pretest and 17,18% With less good category, while the quality of less effective learning with 0% percentage in the experimental class and 0% for the control class in the category of less effective, student's 0% complete student completeness and incomplete start in pretest experimental class and 4.76% unfinished postest, and 0% at pretest with unfinished category, 14.29% also incomplete for postest control class, and 0% completeness of subject matter and unfinished acceptance in experiment class and 0% unfinished in control class Pretest and postest Thus, it can be concluded by using the programming language used for learning English on Basic Physics course I on the mater I collision and momentum.

Abstract

This research aims to produce products in the form of printed modules and CDs containing augmented reality (AR) applications. The AR application on the CD was transferred to the mobile phone and installed. Augmented reality technology in the form of 3D animation and video appears by scanning markers or images in the module using the AR application camera on the mobile phone. One of the 3D animations shown is an animation of the earth, while one of the videos shown is a video about layers in the Earth's atmosphere. This research method uses research and development R&D (Research and Development) with the ADDIE model development model. The ADDIE model consists of analysis, design, development, implementation, and evaluation. This research is only up to the development stage. The source of the data used in this research is the assessment score that comes from a questionnaire in the form of a checklist filled out by an expert validator. The data obtained showed that the material validation score was 3.48 (high category) and the media validation score was 3.51 (very high category). The results of this research indicate that the mobile augmented reality-based science learning media on the Earth layer and disaster material has been valid in terms of material and media, so it is suitable to be used as a learning media for the Earth layer and disaster in class VII junior high school.

Abstract

Critical thinking is one of the high-level thinking stages that can be interpreted as a process of thinking precisely, directed, reasoned, and reflective in decision-making that can be trusted. This study was aimed to determine the improvement of critical thinking skills toward Guided Discovery Learning model of grade VIII students at MTs Al-Huda Pekanbaru on light material. The type of research used was experimental research. Descriptive analysis was used to analyze the data. This analysis gave the description about influence of Guided Discovery Learning model toward student's critical thinking ability. The subjects of this study were 58 students. The data was collected based on critical thinking skill's test result which consisted of 15 essay questions for 5 indicators after Guided Discovery Learning model was applied on experiment class and conventional model on control class. Mean score of sudents' critical thinking ability on experiment class was 78.45 which was in a high category and average score of students' critical thinking skill on control class was 70.52 which was in low category. Based on the result of students' critical thinking skill, it can be concluded that there was an improvement of critical thinking ability after guided discovery learning model was applied by 11.24% compared to conventional learning model.

Abstract

Science literacy is the capacity of individuals to use scientific knowledge to be able to make the right decisions related to nature and human interaction. This study aims to produce test instruments based on scientific literacy on energy matter in living systems. The research method used is Research and Development (R & D) using the ADDIE (Analysis-Design-Development-Implemtation-Evaluation) development model. The stages of the study began with an analysis of the problems of science literacy skills of Indonesian students, then proceeded to develop indicators of questions based on the PISA 2015 indicators. After the indicators were developed, they were followed by making questions and question validation by 3 expert validators. Questions that have been validity tested are limited to 31 students. Data obtained from logical validity and limited trials. Then the data is analyzed descriptively. The results of the analysis of the data obtained are, the validation assessment of science literacy-based test instruments on energy material in living systems by experts is 79.39% with valid validity levels, while the assessment of limited trials is obtained from the validity of 17 questions declared valid and have value reliability of 0.6 with moderate reliability.
