The goal of this research is gaining description on science literacy improvement of junior high school students regarding the topics of earthquake and flood as an effect of Contextual Based Learning (CBL) implementation during science instruction. Quasi-experiment serves as the method of this study with non-equivalent control group pre-test post-test design. Jigsaw cooperative learning method functions as the control treatment. Research subjects involve 52 students of grade VII in a state junior high school in Bandung Regency, West Java. Those research subjects are divided into two classes namely experiment class and control class. The instrument used to collect relevant data is science literacy test covering aspects of science content, science competence, and attitude towards science. Two independent sample t-test is applied to analyze the comparison of science literacy improvement reached between experiment and control class. The result of statistical calculation for two independent sample t-test N-gain using version 23 SPSS software shows a significant value of 0.00 < α. 0.05 for all aspects. The findings indicate that CBL implementation during science instruction within topics of earthquake and flood is proven to be valid to improve students’ science literacy compared to jigsaw cooperative model.

This study aims to obtain a valid scientific-based physics learning module to improve critical thinking skills in Dynamic Fluid material for high school/MA students. This study uses a research development design and approach or is included in development research. In this study, a scientific-based physics learning module was developed. The development of this module refers to the development of the (4-D model) proposed by Thiagarajan. This model consists of 4 development stages, namely (Define, Design, Develop, and Disseminate). However, this study is only limited to the development stage, namely the validation stage. The validation test is a theoretical validation. Namely, assurance carried out by experts in their fields. The confirmation includes material, media, language, teacher and peer validation. The research results found that the physics-based learning module was scientifically based on improving critical thinking skills in Dynamic Fluid material for high school / MA students, which were developed to meet the validity criteria. In conclusion, the physics-based learning module to improve critical thinking skills in Dynamic Fluid material for high school / MA students is very well developed.

Basic phylogenetics and associated “tree thinking” are often minimized or excluded in formal school curricula. Informal settings provide an opportunity to extend the K–12 school curriculum, introducing learners to new ideas, piquing interest in science, and fostering scientific literacy. Similarly, university researchers participating in science, technology, engineering, and mathematics (STEM) outreach activities increase awareness of college and career options and highlight interdisciplinary fields of science research and augment the science curriculum. To aid in this effort, we designed a 6-h module in which students utilized 12 flowering plant species to generate morphological and molecular phylogenies using biological techniques and bioinformatics tools. The phylogenetics module was implemented with 83 high school students during a weeklong university STEM immersion program and aimed to increase student understanding of phylogenetics and coevolution of plants and pollinators. Student response reflected positive engagement and learning gains as evidenced through content assessments, program evaluation surveys, and program artifacts. We present the results of the first year of implementation and discuss modifications for future use in our immersion programs as well as in multiple course settings at the high school and undergraduate levels.

The learning process used in the X class of Computer Engineering and Computer Networking Competition classes still use teacher centered method, where teachers are more dominant than the students in the learning process. Thus, students who do not have the motivation to learn or not pay attention to the process of learning instead of opening an online game for the browser or active with social media.This study aims to apply e-learning based on moodle Problem Based Learning method in SMK Negeri 1 Pasuruan. The subjects of this study are students of class X TKJ 1 SMK Negeri 1 Pasuruan, amounting to 36 people. To know the teacher and student response to the implementation of moodle based e-learning mnggunakan problem based learning method obtained by using questionnaire method / questionnaire. Based on the results of the research, the conclusion that can be taken is the application of moodle based e-learning using problem based learning method on the subjects of Computer Assembly class X TKJ 1 has been tested. From the results of questionnaire data analysis given to the teacher respondents obtained an average percentage score of 81.87% and student respondents got an average percentage score of 88.86%. This shows that the application of moodle based e-learning using problem based learning method in SMK Negeri 1 Pasuruan is very effective and in terms of moodle performance using problem based learning method in its application can be quite good.

The purpose of this study was to determine the effect of the cooperative Student Teams Achievement Devision (STAD) learning model on the ability to understand students 'mathematical concepts and students' responses to the STAD cooperative learning model type. This research method is a quasi experimental method. This research was conducted in State 2 Junior High School of Sorkam at the even semester of the 2016/2017 Academic Year. The sample of this study was class VIIIA as the experimental class and VIIIB as the control class. From the research data obtained a regression equation Y = 74,857 + 8.857X (there is a positive effect). The average value of students' understanding of mathematical concepts learned by the STAD cooperative learning model is 83,714, while the conventional learning model is 74,857. The coefficient of determination is 21.6%, meaning that 21.6% of the influence of the STAD type cooperative learning model on the ability to understand students' mathematical concepts. The results of the analysis of student responses were obtained (1) by 98.2% stating they were interested and the rest not; (2) amounting to 95.05% stating that there are benefits obtained and the rest not; (3) amounting to 86.78% stated that there were no obstacles experienced during the learning process and the rest stated there were; (4) 94.04% hoped the STAD type cooperative learning model was used in the learning process and the rest did not expect. So, it can be concluded that the student response is very positive because the average percentage of student approval responses to the STAD type cooperative learning model is ≥ 85%.
