Abstract

The research on developing a chemistry practicum guide based on problem based learning colloid material for class XI SMA students aims to determine the effectiveness of the developed practicum guide. Research and Development (R&D) is this type of research using the Plomp model. The Plomp model has 3 stages, including: 1) preliminary research, 2) prototype stage, 3) evaluation stage. The validity of this practicum guide was tested by two chemistry lecturers from FMIPA UNP and two chemistry teachers from SMAN 2 Rambatan and SMAN 1 Rambatan using a validation instrument. The validity of the validators was analyzed using the Aiken's V formula. The results of the construct validity analysis with Aiken's V average score of 0.84 were included in the very high validity category and the content validity 0.86 also included in the very high validity category. The data obtained indicate that the PBL-based colloid practicum guide for class XI SMA/MA students is valid and practical.

Abstract

Chemistry is a branch of natural science that is closely related to everyday life. Until now, it is mandatory to learn at the high school level is chemistry subject matter of chemical equilibrium. Chemistry lessons at this time tend not to be of interest to students because they are considered difficult. Based on data from interviews with several chemistry teachers at SMA 14 Padang, the material for chemical equilibrium was still difficult for students to understand, where learning at school was still teacher-centered. The solution is to apply the LSLC-based GDL model to encourage active students and improve quality and improve the course of a learning process. this type of research is quasi-experimental. the results of the research data are normally distributed and homogeneous, so the hypothesis test that is carried out is the t-test with 0.03 < 0.05. That is, the learning outcomes with chemical equilibrium material for students who were given treatment using the LSLC-based GDL model were higher than the learning outcomes of students who applied the GDL model without LSLC.

Abstract

The selection of learning models that have not been carried out optimally by educators so that a learning system is needed that supports this learning model. One learning system that can be applied is a lesson study-based learning system for learning communities. The key to the implementation of lesson study for learning community is in the reflection (see) stage so that the learning process has increased and has an impact on increasing teacher competence and improving student learning outcomes. The purpose of this study was to reveal the effect of the guided inquiry learning model based on lesson study for learning community on salt hydrolysis material on student learning outcomes of SMAN 10 Padang. This research is a quasi-experimental in the form of nonequivalent control group design. The analysis carried out obtained the results of data that were normally distributed and the variance was homogeneous so that it fulfilled the requirements of the t-test and obtained a sig(2-tailed) value of 0.001 < 0.05. Based on data analysis, it was concluded that the guided inquiry learning model based on lesson study for learning community on salt hydrolysis material has a significant effect on student learning outcomes.

Abstract

ABSTRACT The learning process carried out at MAS PSA Sulit Air still uses the lecture method and the learning resources used are in the form of textbooks, and have never used learning modules, thus causing students to be less active in the learning process. While in the 2013 curriculum it is said that during the learning process students must be actively involved. Efforts to make students actively involved in the learning process is to use teaching materials in the form of learning modules. This study aims to reveal the effect of using the buffer solution module on the learning outcomes of class XI IPA students at MAS PSA Sulit Air. Type of research is a quasi-experimental with a non-equivalent control group design. The research instrument used was a test of student learning outcomes in the form of 25 objective questions that had been tested. The data from the test results show that the data is normally distributed and homogeneous, so that hypothesis testing can be carried out with the t-test. From the results of the t-test, obtained Tcount>Ttable at a significant level of 0.05, it is stated that H1 is accepted. This means that the experimental class student learning outcomes are significantly higher than the control class. The results showed that the use of the buffer solution material module could improve student learning outcomes in class XI IPA at MAS PSA Sulit Air.

Abstract

Variation of learning media is e-LKPD (electronic Student Worksheet) with Flip PDF Professional. Making e-LKPD is an effort to improve critical thinking skills, understanding concepts and linking the acquired knowledge to real life through integrated learning. The approach that can be used is STEM (Science, Technology, Engineering and Mathematics) which is usually followed by several learning models, one of which is PjBL (Project Based Learning). The purpose of this study was to develop an integrated STEM-PjBL e-LKPD on acid-base material for class XI SMA. This type of research is Research and Development which uses a 4-D development model, define, design, develop, and disseminate. The data analysis used is validity and practicality. The data analysis technique uses Aiken'sV to analyze the validity of the data and Kappa Aiken'sV Cohen to analyze the practicality of the data. The average Aikken'sV validity test scale is 0.85 with a very high validity category. Aikken'sV scale. The practical kappa moment of the teacher's practicality sheet is 0.90 in the very high category and from the student's practicality sheet, 0.82 is in the high category. This shows that the integrated STEM PjBL e-LKPD on acid-base material for class XI SMA which was developed is valid and practical as a learning media.
