Electrolyte and nonelectrolyte based discovery modules are available learning is valid and practical, but has not been tested its effectiveness. Therefore the study aims to reveal the effectiveness of electrolyte and nonelectrolyte solution modules on students' learning outcomes and critical thinking skills. The module effectiveness test is done through quasi experimental research with Pretest-Posttest Control Group Design design. Research population of all students of class X MIPA SMAN 2 Bukittinggi. The sample was taken by purposive random cluster sampling technique.. The research instrument used in the form of learning result test and critical thinking skill assessment sheet. Techniques of data analysis of learning outcomes by using SPSS 16 software and critical thinking skills with percentage techniques. Based on the result of the research, it is found that the experimental class N-gain (0.76) is higher than control class (0.67). The data analysis technique showed that the experimental and control classes were normally distributed and had homogeneous variance, so the t-test was performed. From the result of t-test analysis obtained (sig) 0.006 <0.05 which indicates that experiment class learning outcomes are significantly higher than control class. Based on the data analysis of students critical thinking skills, the average score of students' critical thinking skills is 87%. The research findings show that the use of electrolyte and nonelectrolyte based discovery modules learning effective on student learning outcomes and critical thinking skills at SMAN 2 Bukittinggi

The purpose of this research are to knowing the differences of critical thinking skills using interactive module photoelectric effects  with printed module, describe the improvement of students' critical thinking skills after the interactive module is applied, describe science process skills in students who use interactive module of photoelectric effects, and knowing student responses to the use interactive module of photoelectric effects. The study was conducted in Natar 1 Public High School, in the even semester 2018/2019 academic year with research design nonequivalent control group design.The research instrument used was a questionnaire (questionnaire), Student Worksheet (LKPD) along with observation sheets and test questions. Data collection techniques were carried out by test techniques, questionnaires and LKPD contents. The data analysis technique of critical thinking ability is done by normality test, homogeneity test and N-gain. The data analysis technique of science process skills is done by calculating the average grade of the class then adjusted to the index classification table of science processes. Hypothesis testing is done by Paired Sample T Test and Independent Sample T Test. The results of the study show that (1) the application of the photoelectric effect interactive module is able to improve students' critical thinking skills, this is seen from the N-gain value and paired sample t test results, 2) there are significant differences in critical thinking skills between students who use interactive modules with printed modules, this is seen from the differences in the n-gain values of both classes and the results of the independent sample t test, (3) the value of students' science process skills is 82.6 with a high category, and (4) students gave a positive response to the utilization of the photoelectric effect interactive module.

Implementation of Curriculum 2013 requires students to learn actively, independently, and critical thinking. Critical thinking is an activity through thinking about ideas related to concepts or problems. The efforts to improve critical thinking skills of learners can be done by using the appropriate learning model. One of the learning models that can be used to improve the ability of critical thinking is a problem-based learning model. This type of research is quasi experiment with randomized control-group pretest posttest design. The sample of this research choosed by used purposive sampling method. Class VIII6 as experimental class and class VIII4 as control class. Data of this research result are quantitative data of critical thinking ability. Data were analyzed by using t test. The results showed that the mean difference of posttest value with pretest value of critical thinking ability of experimental class learners is higher than control class. Hypothesis testing with t-test obtained tcalculate=2,94>ttable= 1,67, then H1 accepted. Based on these results the authors conclude that the implementation of problem-based learning model has a positive effect on the ability to think critically learners on the material additives and addictive substances.

Critical thinking is an important thing in building learners' knowledge. Students who have these skills will be able to solve problems effectively. This study examines the effect of science teaching materials based on the 5E learning cycle integrated with local wisdom in terms of gender on students' critical thinking skills. This quasi-experimental research with a pre-test-post-test control group design was carried out at Madrasah Tsanawiyah. Purposive sampling was used to select the research sample, including an experiment and a control group of equal ability between male and female students. The data were analyzed using a t-test and N-gain test to determine the improvement of critical thinking skills in both groups. The results showed that this teaching material affected students' critical thinking skills by the results of the t-test. The difference in the improvement of students' critical thinking skills is significant based on the result of N-gain and categorized as high. Students become more critical in solving problems after study using 5E integrated by local wisdom. The result shows an impact of this teaching material on first to fourth indicators of critical thinking skills. The fifth indicator is not affected by this teaching material because of students' weakness in elaborate the solution. There were also significant differences in the improvement of male and female students' critical thinking skills. One of them is that male students have a quicker response and higher self-confidence than female students in solving the problems. Based on this result, we conclude that applying science teaching material with 5E integrated by local wisdom positively affects students' critical thinking skills.

The learning process only focuses on the material by memorizing concepts, students do not use LKPD to do practical work optimally, so the biology learning process in schools does not encourage students to practice critical thinking skills. This study aims to improve students' critical thinking skills by using the PBL learning model combined with STEM-based worksheets on environmental pollution conceptin class 10th SMA Negeri Bireuen district. The approach used is experimental design, the method used is quasi-experimental, with a pretest-posttest design non-equivalent control group design. Population in class 10th IPA SMAN 1 and SMAN 2 Peusangan designed 252 people. The sampling technique used was purposive sampling technique. The research sample was 140 students. The number of samples in the experimental class was 71 people and 69 people in the control class. The instrument used was a reasoned multiple choice question accompanied by a rubric. The data analysis used was n-gain and independent t-test. The results showed that the critical thinking skills obtained was 0.93, with an increase in class critical thinking skills including the high category. The results of the independent sample t-test obtained Sig. (0,000) α (0.05) then Ha is accepted, so it is suggested that there are differences in the critical thinking skills of students between the experimental class and the control class on environmental pollution material in class X SMAN Bireuen. The implementation of PBL learning model combined with STEM-based LKPD can improve students' critical thinking skills on environmental pollution material in class 10th SMA Negeri Bireuen Regency.
