Ethno and science provide a dimension of togetherness in the development of society's culture and science. The aim of the study was to determine the perceptions of prospective chemistry teachers towards ethnoscience in contextual-based learning. The method used in this research is qualitative. Sources of data were taken from 39 first and second level chemistry teacher candidates and then specified into seven tribes in seven districts/cities in South Sumatra. The research instruments are surveys, interviews, and observations. Data were analyzed based on an interactive analysis model. The data analysis technique is to reduce the data and then draw conclusions. This study shows a positive perception of prospective chemistry teachers towards ethnoscience, that is, they are able to understand and elaborate on the ethnoscience approach in basic science lectures. The main problem faced by prospective chemistry teachers in the ethnoscience approach is that they are not used to connecting science content based on the chemical context with local culture. Ethnoscience approach can be implemented with Contextual Learning. This learning provides an opportunity for prospective chemistry teachers to further explore the culture of the surrounding community in a more real way. Contextual Learning helps and bridges the process of discovering concepts and contexts that exist in learning.

The lack of didactic anticipation as reflected in lesson plans can have an impact on the less optimal learning process for each student so that learning obstacles arise. One effort to overcome this is to design learning through didactic design. This study aims to develop a didactic design in reducing learning obstacles in the concept of redox reactions. The method used in this research is a qualitative research method. The research design used is Didactical Design Research (DDR). Data collection techniques used are tests, observations, interviews and documentation. Respondents in this study were 30 students of the UPI Pilot Laboratory High School in class XI IPA 2 and 28 students in class X. Based on the results of the study, it was found that the didactic design developed in the form of Chapter Design and Lesson Design included providing an understanding of concepts through the provision of phenomena followed by experiments or demonstrations in general, which ran smoothly. The existence of Chapter Design and Lesson Design components aims to make students obtain the material. The other goal is to make it easier for teachers to achieve better educational goals by bringing out predictions of student responses and prepared teacher anticipation. This didactical design can reduce learning barriers and can improve students' abilities. It can be concluded that the didactic design of the concept of oxidation-reduction reactions is effective as an alternative teaching material used in the learning process.

This study is motivated by problems related to low student learning outcomes caused by the use of learning resources that are still ineffective and the learning process is still focused on the teacher as the main learning resource. This study aimed to determine the effectiveness of a POE (predict, observe, explain) based chemistry learning module in electrolyte and non-electrolyte solution material on students’ learning outcomes. This was experimental research in the form of pre-experimental with a one-group pretest-posttest design model. The sample in this study was students of class X IPA at one of the public high schools in the Ogan Komering Ilir District, and the sampling in this study used a simple random sampling technique. The data collection technique used in this study was in the form of tests where the instruments were pre-test and post-test questions in the form of multiple choice questions. The effectiveness of the module is seen from the results of data analysis of student learning outcomes using n-gain score and t-test data analysis. Based on the analysis of the n-gain score data, an average score of 0,58 was obtained which was included in the medium category, and the hypothesis test results obtained a sig (ρ) value of 0,000 ˂ 0,05, which means H0 is rejected and H1 is accepted. Based on the analysis results, it was concluded that POE (predict, observe, explain) based chemistry learning module is effective for students’ learning outcomes and can be used as an alternative teaching material.

Virtual chemistry laboratories (VCLs) are the alternative solutions of the physical laboratories, where students can virtually conduct their experiments with a lower cost, and in an efficient and safer way. Considering the importance of technology-enhanced learning and that of the experimental study, several VCLs have been proposed. However, the existing VCLs are static and only provide the simulation of pre-defined experiments, procedures, or safety procedures and cannot be adapted according to the students’ level or new experimental tasks. In this paper, we proposed a dynamic virtual chemistry lab (DVCL) where instructors or experts are allowed to add a new chemical experiment by adding its apparatus, chemicals, glassware, and mechanism or add something new to its properties. We conducted a subjective study with field experts to investigate the effect of proposed DVCL in secondary school chemistry education. During evaluation, twenty-seven field experts were participated and evaluated the proposed DVCL with system usability scale (SUS)-questionnaire and by a simple questionnaire. The results showed that the proposed DVCL is very helpful for students’ performance and mental modeling and also for effortlessly uplifting their knowledge for hands-on experiments.
