Science Data

Acid-base is one of topics considered difficult by students. This concept is broad,  varied. Despite it is very closely related to everyday life, its application was still lacking. The development of teaching materials in the form of a module was deemed to be a solution to this problem. The aim of this research was to develop CTL module with green chemistry orientation in acid-base subject material to improve science literacy of students. This study was developed ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model. The developed product was validated by three experts, a practitioner and ten high school students. Data were analyzed using percentage formula. Qualitative data in the form of comments and suggestions from validator were used as consideration to revise the developed module.Tthe effectivity of the module was assessed using N-gain test. Based on validation results, we obtained average of 86,5%, 97%, 88%, and 94,58%. Effectivity evaluation using N-gain test shows an average score of 0,5 with moderate category. Result of student attitudes towards science data has an average score of 74% with good qualifications. It was concluded that developed module prototype is effective for acid-base topic, and most likely for other topics in learning process and growing student science literacy.

Experience Difficulty

One of the chemistry conceptsthat was considered difficult by students was acid-base concept. Acid-base conceptwas closely related to everyday life and includes three representations of chemical levels, namely: macroscopic level, microscopic level and symbolic level, so students experience difficulty in learning it. The development of a teaching material in the form of LKS was seen as a solution to this problem. This study aimed to develop teaching materials in the form of POE LKS oriented to green chemistry to foster students' scientific attitudes towards acid-base concepts. This studywas development research with ADDIE (Analysis, Design, Development, Implementation, and Evaluation)model design. Quantitative data from the results of feasibility validation and the results of assessment of scientific attitudes of students were analyzed by percentage formula and the results of student responses were calculated using N-gain. Qualitative data in the form of responses and suggestions for improvement from the validator. The validator's assessment of the results of the development obtained an average percentage of 83.2%, 84%, 81.6%, and 78.93%. While the responses of students were analyzed using the N-gain test obtained an average score of 0.4 with a moderate category and students' scientific attitude data obtained an average score of 61% with moderate qualifications. This showed that the LKS developed was very feasible to proceed to a broader stage and effectively improve students' scientific attitudes.

Learning Interest

The obstacle faced in the learning process so far is the low interest in student learning. Many factors affect interest in learning, one of which is the lack of variety of teaching materials or learning media used by teachers in schools. The use of augmented reality (AR) in education is an important topic of research although its use is still in its infancy. The purpose of this research is to develop learning media, AR-based e-magazine to increase students' interest in learning high school students, on the material of the digestive system. The development of the e-magazine is carried out using the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model. The parameters in this study are the quality of the e-magazine and interest in learning. Testing interest in learning is done using an interest questionnaire given to students for the control class consisting of 36 students and the experimental class consisting of 36 students. The results of the development of AR-based e-magazines are relatively good. This can be seen from the validation results with a very valid category. Based on the didactic aspect, a score of 3.82 was obtained in the very valid category, the constructive aspect was 3.85 in the very valid category and the technical aspect was 3.78 in the very valid category. The results showed that the use of AR-based e-magazines increased interest in learning. Interest in learning obtained a score of 0.342 in the high category. Thus, it can be concluded that the use of AR-based e-magazines as digital learning media can be used in the learning process.

Use Of Technology

Adolescents are currently in the midst of technological sophistication, which is very helpful for its development. On the other hand, many adolescents are trapped in the problem of technology addiction. Adolescents are the most age group who experience problems with the use of technology, including online games. Online game addiction is the loss of control over the use of online games, which makes other daily activities are disrupted. Online game addiction in adolescents have an impact on several aspects of life, such as health aspects, psychological aspects, academic aspects, social aspects, and financial aspects. Lack of understanding about the risks of online game addiction can get adolescent stuck in online game addiction. This research aims to describe high school students understanding about the risks of online game addiction. The sample consisted of 255 high school students selected by proportional random sampling technique. Data was collected using a scale measuring understanding of the risks of online game addiction. Data analysis used a quantitative approach with descriptive methods. The results showed that high school students understanding about the risks of online game addiction was included in the moderate category with an average score of 198,48 and an achievement score level of 55,14%. Therefore, school counselors must to improve high school students understanding of the risks of online game addiction.

Post Hoc

Students often struggle to connect concepts with evidence, sometimes because development of research skills has not been emphasized in their science courses. We developed a strategy and protocol to train high school students in research and experimental investigation of questions related to course material on legume biology. The richness of this subject matter allows for adaptations of our framework to address diverse areas of science, including principles in ecology, environmental science, agriculture, microbiology, and evolution. Our framework includes a hands-on classroom inquiry that investigates the symbiotic relationship between nitrogen-fixing rhizobial bacteria and legumes. This student-led, inquiry-based project employs an intellectually demanding, hands-on method of education to build critical research skills using an adaptable model and inexpensive materials. We also report positive student feedback from a post hoc survey to gauge student attitudes toward the activity and the effectiveness of this framework.
