The implementation of Contextual Teaching and Learning (CTL) based on lesson study aimed to determine its effect on the biology learning achievement of high school students. This referred to quasi-experimental research by applying CTL learning based on lesson study to the experimental class and conventional learning in the control class. The population in this study amounted to 286 students (Science X class students of SMA Negeri 2 Jember). The sample in this study was determined through homogeneity test, normality test, and random sampling to determine the control class and the experimental class. The students' affective learning achievement was analyzed by using the independent sample t-test, while their cognitive learning achievement was analyzed by using ANAKOVA test. Based on the test results of the independent sample t-test, it was found that the students' affective learning achievement differed significantly between the students in experimental class and control class. Based on the results of ANAKOVA test, it was known that the application of CTL learning based on Lesson Study has a significant effect on students' cognitive learning achievement.

This study aims to develop a module based on discovery learning in improving scientific literacy skills in the 11th grade of science class in senior high school. This study refers to the modified Borg and Gall model into 7 steps, (1) preliminary study; (2) planning; (3) preparation of modules; (4) expert judgment; (5) revisions; (6) limited trials; (7) revision II. The research samples are in XI MIPA 2 and XI MIPA class at 3 SMAN 1 Bringin. The technique of collecting data using written tests, questionnaires, and observations. Hypothesis testing to measure the increase in cognitive learning outcomes of students using an independent t-test on n-gain students. Assessments from material experts, subject matter teachers, colleagues, and high school students show that the modules that have been developing suitable for use in the learning process with an achievement level of 86%, 95%, 88%, and 90% respectively. The results of the t-test showed an increase in students' literacy skills (p <0.05) of 0.71 (high category). It can be concluded, the modules that have been developing become worthy to use in the learning process and effective in enhancing the scientific literacy skills of senior high school students in XI class.

The Effect of Self-Efficacy, Learning Activities and Learning Independence on Biology Learning Achievement in Class X Students of Public Senior High Schools in Namlea District.The formulation of the problem in this study is how the effect of self-efficacy on student achievement in high school students in Namlea sub-district. This study aims to determine the effect of self-efficacy on the learning achievement of biology class X students in Namlea district. This type of research is ex-post facto which is causality designed to explain the existence of a causal relationship between variables. The population in this study amounted to 603 students of State Senior High School in Namlea district. The sample in this study amounted to 90 students. The data analysis technique used simple linear regression analysis.The results of the analysis show that self-efficacy has a positive and significant effect on the biology learning achievement of class X SMA Negeri in Namlea sub-district.

In 21st century learning, critical thinking skills are the main choice that must be mastered by students. This study aims to determine the effectiveness of local wisdom-based science teaching materials in improving junior high school students’ critical thinking skills. Most science teachers still apply teacher-centered learning, so students tend to be passive. This type of research is quasi-experimental with a pretest-posttest control group design. The study was conducted in the even semester of the 2019/2020 school year. The subjects of the research were grade VII students. Data collection techniques and instruments in the form of tests that include indicators of critical thinking skills. Data analysis used homogeneity test, Kolmogorov Smirnov normality test, independent sample t-test, and n-gain score. The results of the independent sample t-test are sig. (2-tailed) = 0,000<sig. α = 0.05. Students’ critical thinking skills in the experimental class were higher (N-gain score = 39.09%) than in the control class (N-gain score = 12.03%). Based on the study results, it can be concluded that there is a significant influence on the application of local wisdom-based teaching materials in improving the critical thinking skills of middle school students in the moderate category.

Teenagers, who are considerably susceptible to smoking, must be educated to prevent smoking behavior that can cause health problems and even death. The aim of this study was to assess the effect of education through social media such as WhatsApp in the modification of smoking behaviors among senior high school students in Pangkep District, Indonesia. It employed a quasi-experimental, pretest-posttest-only control group design. The experimental group received education in the use of WhatsApp social media, while the control group was provided with leaflets. Data were collected through observation and interviews with a total of 180 students in both groups, with 90 students in each. Data analysis used a paired sample t-test and an independent sample t-test. The study suggested that disseminating health information through WhatsApp media about the dangers of teenage smoking was more effective than leaflets in changing student behavior.
