The problem of research at SMPN 34 Padang is the low level of Science Process Skills of students from the results of previous observations by carrying out tests conducted in class VII SMPN 34 Padang, showing the average science process skills of students is less than 50%. This study aims to look at the effect of the Problem Solving Model on Science Process Skills in Grade VIII students of SMPN 34 Padang. In Indonesia science process skills is very minimal, because in the learning process the teacher still tends to use the lecture model and question and answer method, so the science process skills is not given to students. This type of research is quasi-experimental with research design Control Group Postest Only Design. The population in this study were eighth grade students of SMPN 34 Padang in the academic year 2018/2019. The samples from this study were class VIII6 as the experimental class and VIII7 as the control class. The research instrument used to view the science process skills of students is the Observation Sheet for Student Activities observed by the observer. Based on the results of research on the knowledge competencies of students, the tcount 4.96> t table 1.67 The Science Process Skills Activity of students in the experimental class was higher than the control class. The conclusion of the study was that the application of the Problem Solving Model had a positive effect on the Science Process Skills of Grade VIII students of SMPN 34 Padang.

This study aims to analyze the effect of feedback from local content-based practicum modules on students' science process skills. Research subjects for product trials developed in this study were students of class XI using a purposive sampling technique with a sample size of 60 students. The method used in this research is quasi-experimental (quasi-experimental). The research instrument was a feedback rubric on applying a local content-based practicum module, observation sheets, and tests on the results of Science Process Skills (KPS). Data processing and analysis is carried out by comparing the initial and final science process skills scores by looking at the science process skills N-Gain score. Hypothesis testing uses the T-test to apply a local content-based practicum module on science process skills by analyzing the initial and final science process skills scores. The highest percentage result lies in the indicator of planning an experiment or investigation and using experimental tools and materials, namely 90%. There is a difference between a class that implements a local content-based practicum module and is given feedback with a class that uses a regular module for each class. The experimental class had an N-gain value of 0.75 or in the high category, while the control class had an N-gain value of 0.64 or in the moderate category. There are differences in students' Science Process Skills (KPS) using local content-based practicum modules with conventional practicum modules.

This study aims to describe the science process skills of students on each indicator and to find out the average percentage of students who have a science process skill level category (high, medium, and low) chemical bonding material with the POGIL learning model. This research uses pre-experimental research with the one group pretest posttest research desaign. The data collection techniques used were observation and assessment tests. The data analysis technique used paired T-Test (SPSS version 16) and N-gain Score. The results showed that the data were normally distributed, namely the Sig.> 0.05. Paired Sample T-Test obtained Sig. (2-tailed) of 0.00, which means that the test is <0.05. So it can be concluded that the POGIL learning model has a significant effect on the science process skills of students. The science process skills of the five indicators, the classification indicator has the highest average posttest score percentage of 96.21% and the observing indicator has the lowest average posttest score percentage of 71.21%. Science process skills have increased from the average results of the pretest and posttest values, namely from 65.76% to 88.41%. The improvement of science process skills is in the moderate category with the N-gain Score index of 0.67.

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.
