Abstract

This study was conducted to determine the percentage and causes of student misconceptions in electrochemistry using the Four-Tier diagnostic test instrument. The research was conducted using a quantitative-qualitative descriptive method. The data collection technique was done through written tests with four-tier diagnostic test instruments and non-tests through interviews. The research subjects were students of the 2021 batch of Chemistry Education at FKIP Lambung Mangkurat University Banjarmasin. The results showed that 34% of students experienced misconceptions. Students experienced misconceptions in electrochemistry and electromotive power (DGL) sub-matter by 25.27%; the thermodynamic aspect of electrochemistry experienced the smallest misconception of 7.69%; DGL and temperature by 12.09%; connecting the Nernst equation with pH measurements by 17.58%; concentration cells by 14.29%; electrolysis by 12.64%; and corrosion sub-matter by 10.44%. Misconceptions occur in electrochemical materials because students think that salt bridges play a role in accelerating reactions. Students were confused about determining the relationship between DGL and temperature; and they were less careful in determining whether a chemical reaction is spontaneous or not. In addition, students were less careful in determining the actions of the gilding process.

Abstract

Research has been carried out on the development of e-modules to improve student problem solving on ethnoscience integrated colloidal material using the problem based learning model. This study aims to determine the validity, practicality, and effectiveness of the e-modules developed. This research is a research development research with the ADDIE model (analysis, design, development, implementation, and evaluation). The subjects of this study were 5 validators and 33 students of grade XI MIPA 5 SMA Negeri 2 Banjarmasin. Data collection using test and non-test instruments (questionnaires and observation sheets). Data analysis using descriptive techniques. The results of this study show that this e-module is very valid, very practical, and effective. The N-Gain value is 0.89 in high category, which is that this colloidal e-module is able to improve problem solving capabilities.

Abstract

The rapid development of education in the Industrial Revolution 4.0 in various sectors of life in science and technology is a source of its own challenges for a teacher in the learning process, especially for preparing the teaching materials. This study aims to develop an E-Magazine that is valid, practical, and effective. This study applied Research and Development method with the ADDIE model. The subjects for this research are 32 students of SMAN 9 Banjarmasin in the academic year of 2021/2022. The trial implementation consisted of individual, small group, and limited trials. Data collection techniques were validation sheets, readability and response questionnaires, and test and non-test assessments while the data analysis used descriptive analysis. The results showed that the validity of the e-magazine with an average score of 4.6 categories was very valid in terms of content, presentation, language, and media aspects. The effectiveness which was seen based on N-gain for students' conceptual understanding was 0.67 (moderate) and learning motivation was 0.45 (moderate). This study shows that the use of e-magazines with SEL approach on colloid material in context of local wisdom is effective, and can be used in chemistry learning. Implications of SEL can help the growth of problem solvers, and collaborative academics is positively synergized with SEL and local wisdom (CASEL-LW) so that students can understand and solve the problems better.

Abstract

E-module development based on flip pdf professional is a systematically arranged instructional material. This research aimed to determine the impact of student learning outcomes when using the developed e-module. The research method used is R D with a 4-D development model: define, design, develop and disseminate. The developed e-module trial was conducted offline for students at SMAN 10 Banjarmasin. The data analysis technique was descriptive statistics. The data collection techniques were validation sheets, response questionnaires and test assessments. The results showed that the developed e-module was stated to be very valid regarding the content feasibility, presentation, language and media. The developed e-module also fulfills practical aspects, seen from student response questionnaires and teacher activity sheets which get very good categories. The e-module also fulfilled the effectiveness aspect based on the N-gain of student learning outcomes included average category. The success of e-module in improving learning outcomes can also be seen from the increased average value pre-test and post-test, from 43.75 to 83.75. The results of the research show that the developed e-module is feasible to use and also improves learning outcomes

Abstract

Science process skills play a crucial role in constructing knowledge and fostering the ability to independently solve problems. Despite their significance, the science process skills of students across various educational levels remain at a relatively low level. This research seeks to evaluate the science process skills of students and their responses to learning about colloids through a blended learning-based guided inquiry approach. The research employs a quasi-experimental design with a pretest-posttest control group setup. The sample, drawn through cluster random sampling, consists of students from Class XI MIPA 1 at SMAN 11 Banjarmasin, divided into two groups. Group A, the experimental class, engages in blended learning-based guided inquiry, while Group B, the control class, follows the guided inquiry model. Data collection involves tests to assess students' science process skills and non-tests to gauge their responses. The analysis entails descriptive techniques and t-tests. The findings indicate (1) discernible differences in science process skills between classes employing blended learning-based guided inquiry and guided inquiry alone, and (2) a positive response from students towards the blended learning-based inquiry model.

Abstract

This research is Classroom Action Research (PTK) which aims to determine the increase in critical thinking skills and student learning outcomes after learning using an e-module based on Scientific Critical Thinking (SCT) on buffer solution material. The research model developed by Kemmis and Mc Taggart consists of 4 stages, namely planning, implementing actions, observing and reflecting in each cycle. The research subjects were 36 students of class XI MIPA 4 SMA Negeri 4 Banjarmasin. Data collection on critical thinking abilities and student learning outcomes was carried out using test instruments. The research results showed that the students' critical thinking skills test in cycle I was 47.18 in the moderately critical category. while in cycle II it increased to a score of 81.08 in the very critical category. In the knowledge learning outcomes test, in cycle I it was 55.56 in the poor category and in cycle II it increased by 91.11 in the good category. Student responses also showed the agree category, thus the e-module based on Scientific Critical Thinking (SCT) on buffer solution material is suitable for use in learning to improve critical thinking skills and student learning outcomes.
