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.

This study aims to investigate the effect of portfolio assessment in teaching physics and scientific attitude. The research was conducted on students of high school in Singaraja. Research was an quasi- experimental study by using “The Posttest-Only Control Group Design”. The research involved 152 high school students of class X of science as samples, taken with multistage random sampling technique. Portfolio assessment was integrated with physics learning. The implementation of the portfolio assessment included four key elements such as the students' work folders, clear assessment criteria, and self-assessment, and conference between teacher and students. The data needed in this research was the students' scientific attitude which included the aspect of curiosity, respect for evidence, the willingness to change ideas, and critical reflection. Data needed in this research included scientific attitudes students. A Likert scale instrument was used to measure the scientific attitude students. Data were analyzed using analysis of variance with SPSS 20.0 at significance level α = 0.05. The results showed there are differences in the scientific attitude students who take physics learning with assessment portfolios and students who take physics learning with assessment of conventional. The findings of this study indicate that portfolio assessment in learning physics significantly affect the scientific attitude students.

One of nonpharmacological treatments for dysmenorrhea is hypnotherapy. Hypnotherapy is an easy, fast, effective, and efficient way to treat dysmenorrhea by reaching the subconcious. This research aimed to identify the effect of hypnotherapy on dysmenorrhea in junior high school students. This research used a pre-experimental method with one group pretest- posttest design. The population of this research was 117 students and 20 students were chosen as sample with purposive sampling technique. Data were collected from respondents using Verbal Descriptor Scale (VDS) instrument. Data were analyzed in two steps, univariate and bivariate with t-dependent test. The results showed that the average value of dysmenorrhea before intervention is 6.5 and after intervention is 1.35. Hypnotherapy was found to have an effect on dysmenorrhea (t=17,596, p-value 0,001). It was suggested to the school that they should conduct nonpharmacological interventions such as hypnotherapy as treatment of dysmennorhea.Key words: Dysmenorrhea primer, hypnotherapy, SMP.

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.

This study aims to analyze the investigative skills of Junior High School students upon the use of tracker video analysis for 21th century skill.This reasearch was quasy experimental reasearch using non-randomized pretest-posttest control group design. The population was 8th grade of SMP Negeri 4 Depok in academic year of 2018/2019, which consists of 4 classes with a total of 127 students. The samples consist of 30 students of class VIII A and 30 students of class VIII B, which are selected using cluster sampling technique. The Class VIII A was chosen as the control class, which used powerpoint and video, whereas Class VIII B was prepared as the experiment class, which used Tracker Video Analysis. The instruments used were pretest-posttest questions and observation sheet of investigative skill. The data analysis technique used was t-test. The result of this reasearch shows that the analysis through t-test gives a significance level value of investigative skill of 0.024 (Sig. α). This shows that there is an infuence of investigative skill of students upon Tracker Video Analysis.
