Abstract

The purpose of this study was to produce a valid and practical Process Oriented Guided Inquiry Learning (POGIL)-based Student Worksheet (LKPD) on 11th Grade Class Buffer Solution Material at State Senior High School (SMAN) 2 Sawahlunto. This research uses the Research and Development research method with the 4-D development model (define, design, develop, and disseminate). However, the stages in research with this 4-D model are only carried out from the first to the third stage, namely the define stage aims to get an overview of field conditions, the design stage aims to compile and design POGIL-based Student Worksheets (LKPD) on buffer solution material, and the develop stage aims to continue the POGIL-based LKPD on buffer solution material that has been designed with validity and practicality tests. The research instruments used were validation sheets and response questionnaire sheets. The validation sheet was filled by 2 lecturers and 1 chemistry educator. The response questionnaire sheet was filled by 25 of 11th grade students and 2 chemistry educators of SMAN 2 Sawahlunto. The results showed that 1) POGIL-based LKPD on buffer solution material meets the valid criteria with 85.42% validation results. 2) POGIL-based LKPD on buffer solution material has met the practical criteria with educator practicality response questionnaire results of 92.31% and student response questionnaire results of 82.15%.

Abstract

The low learning outcomes of students are caused by limited teaching materials and educators who tend to use the lecture method during learning. This research aims to develop an E-Modules Based on Learning Cycle 8E Integrated with Al-Quran verses on Salt Hydrolysis Material for 11th Grade of Senior High School (SMA/MA) that are valid and practical. This research uses the Research and Development research type with the 4-D development model (define, design, develop, and disseminate). lkpHowever, only the first three stages of the model were implemented in this research. The results showed that 1) e-modules based on Learning Cycle 8E integrated with Al-Quran verses on salt hydrolysis material 11th Grade SMA / MA met the criteria very valid with a percentage of the validity of e-modules based on Learning Cycle 8E is 89%, the validity of content feasibility on integration with Al-Qur'an verses obtained a percentage of 90.6%. 2) e-modules based on Learning Cycle 8E integrated with Al- Quran verses on salt hydrolysis material for 11th Grade SMA/MA have met the criteria of being very practical with the results of the student response questionnaire obtaining a percentage of 84% and educators obtaining a percentage of 93%.

Abstract

This research aims to determine the impact of using the Problem-Based Learning (PBL) module on students' critical thinking skills on the material of electrolyte and non-electrolyte solutions. This research uses a quasi-experimental method with a Nonequivalent Control Group Design. Sampling was carried out by using cluster purposive sampling. The data collection technique used was a critical thinking skills  test instrument in the form of essay questions. Hypothesis testing was carried out by using the independent sample t-test. The result showed that using PBL module on the material of electrolyte and non-electrolyte solutions has a positive impact on the critical thinking skills of students at SMA N 1 Sijunjung and SMA N 7 Sijunjung. This is proven by the results of the t-test analysis using SPSS that the significance value is 0.000 less than 0.05 with a significance level (α = 0.05) so that H0 is rejected and H1 is accepted. This means that the use of the PBL module has an impact on students' critical thinking skills regarding the material of electrolyte and non-electrolyte solutions. The critical thinking skills of students in the experimental class who learned using the PBL module were higher than those in the control class in both schools.

Abstract

This research is motivated by the number of students who experience misconceptions so that they are not successful in chemistry subjects. This study aims to determine the misconceptions that occur in class X students at SMA N 1 Lintau Buo using a three-tier diagnostic test on atomic structure material. In this study using a qualitative approach (descriptive) method. The subjects of this study were class X students with a total of 108 people. The instruments used are the main instrument (the researcher himself) and supporting instruments, namely the three-tier diagnostic test, interviews, observation and documentation. Data validity testing was carried out by increasing persistence and data triangulation. Furthermore, the data analysis technique uses the classification of student answers from the three-tier diagnostic test, then a percentage is obtained based on the atomic structure sub-matter which is grouped into categories of conceptual understanding, misconceptions and not conceptual understanding. Based on the research that has been done, it can be concluded that the results of the analysis of student misconceptions using the three-tier diagnostic test on class X atomic structure material at SMA N 1 Lintau Buo “are that there are two sub-matter of atomic structure with misconceptions with high criteria, namely in the sub-matter of atomic notation based on the number of protons, neutrons and electrons by 69% and sub-matter of isotopes, isobars and isotones by 62%. For the overall atomic structure sub-matter, the average in the concept understanding category is 36% medium criteria, the misconception category is 55.6% medium criteria and the category does not understand the concept of 8.4% low criteria.
