This research was conducted at SMPN 2 Solok City in the 2021/2022 academic year. The type of research used is Quasi Experiment. The research design that will be used is the Non-equivalent control group design. The sampling technique used is purposive sampling. The sample used is class VIII-7 as a control class using a conventional model while class VIII-8 as an experimental class using a cooperative learning model of the NHT type. The instrument used in this study was written in the form of Multiple-choice questions. While the test analysis was carried out using Microsoft Excel, the calculation of the hypothesis test was carried out with the t test after conducting the prerequisite test, namely the normality test and homogeneity test. The results of the t-test calculation are tcount = 3.96 and ttable = 1.67, where tcount> ttable, thus research H0 is rejected and H1 is accepted. This shows that there is an influence on the cooperative learning model type NHT (Numbered Head Together) on the cognitive learning outcomes of class VIII students on the human respiratory system material at SMP N 2 Solok City.

The study population was all students of class IX and the sample class was selected by purposive sampling technique, so that class IX-6 was obtained as the experimental group and class IX-4 as the control group, with a sample of 56 students. This research is a quasi-experimental research with a pretest and posttest group design pattern. The data collected is a test of learning outcomes which are analyzed quantitatively to measure students' scientific literacy skills which are grouped into 3 aspects, namely numerical, conceptual, and multidimensional aspects. The instrument used is a scientific literacy test in the form of 10 description questions. The results show that the res...

While Indonesia has been successful in increasing the access of 15-year-olds to the school system, greater efforts are still needed to educate them so that the percentage of low-achieving students is kept as low as possible. Based on the results of observations made, students' scientific literacy at SMP Negeri in Bukittinggi is still relatively low. This research was a quasi-experimental study with a non-equivalent control group design which aims to determine the scientific literacy profile of students using the Reading to Learn (R2L) model. The R2L model has a main focus on teaching students to read texts and then gain a deeper understanding of the contents of the reading and rewriting what they have learned (note-taking). Based on the results of statistical analysis, the data is normally distributed and homogeneous so that a parametric test (T-test) is carried out. The results of the calcula...

The results of observations in several junior high schools in Tanjung Mutiara sub-district, the teaching materials used are still limited to textbooks, in the learning process teachers still use the lecture or discussion method, and the application of the scientific approach has not been applied as a whole. Based on these problems, a research has been carried out that aims to determine the level of validity and practicality of the Integrated Science-Based E-LKPD Scientific Approach on the Energy Theme for Science Learning in SMP/MTs. This type of research is Research and Development (R&D) using a 4-D model consisting of four stages, namely: define, design, develop, and disseminate. Given the limited time this research is limited to the develop stage. The data collection instrument used was a val...

The purpose of this study was to determine the effect of providing technical guidance (Bimtek) on developing scientific literacy-based worksheets on the competence of science teachers. The Bimtek activity consists of six stages: pretest, material debriefing, technical guidance (Bimtek), independent activities, evaluation monitoring, and posttest. From the Bimtek activities carried out for science teachers at MGMP Pesisir Selatan districts significantly increased teacher competence in developing scientific literacy-oriented worksheets. Based on the results of data analys...

Mastery of science material by students is highly prioritized so that students have the skills to solve daily problems related to science. One of the ways to develop this skill is by doing practical work. Electricity and magnetism are science subject matter that students should follow in the form of practical work because this material has a lot to do with problems in everyday life. However, the limited duration of learning time at school makes some science subject matter that should be studied in the form of practical work cannot be implemented. This happens because of the large amount of material that must be taught in accordance with the demands of the curriculum. Other factors that lead to not carrying out practical work are incomplete science laboratory facilities, inadequate teacher experience, and conditions that do not allow learning to occur directly in schools. The Mobile Virtual Laboratory is a virtual laborat...

One tool that can support this goal is a learning tool based on research-based learning models with a scientific approach. The purpose of this study is to develop high school physics learning tools using a lerning based research model with a scientific approach with valid, practical and effective criteria. The type of research used is research and development. The results of research on the analysis of students obtained that class students have been able to develop the ability to solve problems. In the validity test obtained an average percentage of RPP 85.79%, an average handout of 85.68%, an average LKS of 86.20%, and an average rating of 87.50%. Practicality test results obtained an average percentage of the implementation of the RPP is 89.16%, the average teacher response questionn...

One of the factors behind this is the lack of availability of syllabus-relevant, user-friendly, practical and accessible learning resources on the topics. Therefore, this research and development study aims to produce a valid and practical e-module hyper-content to support the learning process of structure atom and periodical properties of element by preservice science teachers. The e-module was developed through ADDIE model which consists of five stages namely Analysis, Design, Develop, Implementation, and Evaluation. The validity test of the product was conducted through expert judgements and the practicality test was conducted involving 110 third semester students of Science Education Department of Universitas Negeri Padang. Result of the feasibility test indicated that the e-module with hyper-content on structure atom and periodical properties...
