Bibliometric Methods: Analysis of the Development Potential of Ethnoscience-based Science Literacy Modules in Chemistry Learning

2023-12-12T13:02:12+00:00

There still needs to be more research on the potential analysis of the development of ethnoscience-based science literacy modules in chemistry learning using bibliometric tools. Ethnoscience-based science literacy modules still need to be found and used in chemistry learning. This research aims to analyze the novelty and effectiveness of ethnoscience-based science literacy modules in chemistry learning. The subject of this research is a science literacy module based on ethnoscience in chemistry learning. In this study, the researchers also analyzed articles that have been filtered based on topics based on local wisdom-based science literacy modules. The analysis contains several components: title, year, doi, author, method, outcome, and conclusion. The research uses an approach that uses the method of Systematic Literature Network Analysis (SLNA) assisted by bibliometric tools as the medium used in analyzing the article. The data obtained was many articles from the SCOPUS database, which had previously defined some criteria for capturing it. The criteria are related to the year of publication, keyword, and language selection. The application used in this study is the VOS Viewers application. The results show that research related to ethnoscience-based science literacy modules in chemistry learning is still highly feasible, given the numerous constraints in some schools. However, it should be noted that ethnoscience-based science literacy cannot replace scientific literacy globally because of the global literacy capabilities needed in everyday life.

2023-12-23T16:44:26+00:00

Nangka banana (Musa paradisiaca) is one of the most popular bananas in Indonesia. Therefore, the production of waste will increase along with the use of bananas. Nangka banana peel and flesh can be used as an alternative media for mushroom growth because of its high carbohydrate content. The purpose of this study was to observe the growth of Aspergillus niger on alternative media made from nangka banana with concentrations of 8%, 9%, 10%, 11% and 12% and to determine the optimum variation and concentration of alernative media. Aspergillus niger was grown on nangka banana flesh media, nangka banana peel media and mix of nangka banana peel and flesh as well as PDA (Potato Dextrose Agar) media as a positive control using the single dot method. Colony diameter and pigmentation were observed for five days. The variation of nangka banana mix media with a concentration of 12% is the optimum variation and concentration to grow Aspergillus niger.

The Effect of Using Ice Breaking on Learning Motivation of Elementary School Students in Learning Science

2024-02-17T07:43:17+00:00

This research was conducted due to the low learning motivation of elementary school students in participating in class learning, especially in science learning. One of the causes of low learning motivation is the lack of interesting innovations in learning, so that students tend to get bored and bored in learning. This low motivation results in low scientific literacy abilities of students. This study aims to determine the effect of using ice breaking on students' learning motivation and scientific literacy abilities. This research was conducted in an elementary school in a district in West Sumatra. This type of research is quantitative in the form of a quasi-experimental design. The data analysis used quantitative analysis using the Paired Sample T-Test. Based on the pretest results, the average motivation score of the experimental class that applied Ice Breaking was 49.842 and the post-test motivation score of the experimental class was 82.631. Based on the results of hypothesis testing conducted with the Paired Sample T-Test, tcount = 3.8421 and ttable 2.028 with a significant level of 5%. Thus t'count = 3.8421 > ttable = 2.028, it can be concluded that there is an effect of using Ice Breaking on Learning Motivation of Elementary School Students in Learning Science.

Efectiveness of Cooperative Learning Model Type Learning Together (LT) on Learning Outcomes and Creativity of Students on Acid-Base Material

This study aims to determine the effectiveness of Learning Together (LT) type cooperative learning model on learning outcomes and creativity of students on acid-base material in class XI MIPA SMA Muhammadiyah 3 Yogyakarta. The population of this study were all students of class XI MIPA SMA Muhammadiyah 3 Yogyakarta which amounted to 93 students and divided into 3 classes, namely class XI MIPA 1, XI MIPA 2, and XI MIPA 3. The samples of this study were class XI MIPA 2 as the control class and class XI MIPA 3 as the experimental class, each class consisting of 31 students. This research method is a quasi-experiment. The design used is nonequivalent control group design. Data collection techniques using test questions and filling out questionnaire sheets of students’creativity. Data analysis techniques used are normality test, homogeneity test, and hypothesis testing (Mann Whitney test and independent sample t-test). Based on the results of the Mann Whitney test analysis, the Sig (2-tailed) value of 0.000 <0.05 was obtained, so H₀ rejected and H₁ was accepted, meaning that the Learning Together (LT) type cooperative learning model was effective on learning outcomes on acid-base material. Based on the results of the independent sample t-test analysis, the Sig. 0.005 < 0.05, so that H₀ rejected and H₁ was accepted, meaning that the Learning Together (LT) type cooperative learning model is effective on students' creativity in acid-base material.

Development of E-LKS (Electronic Student Worksheets) Contain Hots (Higher Order Thinking Skills) Students in Science Learning

2024-03-24T08:51:34+00:00

Worksheet is one of the learning tools that plays an important role in students' thinking processes. The thinking process in achieving 21st century skills is that students can have higher order thinking skills (HOTS). The objectives of this research are: (1) How do teachers and students respond to the development of E-LKS which includes students' HOTS in science learning?, and (2) How to increase students' HOTS in using E-LKS in science learning? learning?. The research subjects were students of class VIII SMPN 4 Sumenep. This study uses the Research and Development approach and the four-dimensional research and development model by Thiagarajan. Our E-LKS validity data is obtained from Content Validity Index (CVI) analysis. Teacher and student response data were obtained by using response questionnaire analysis. Data on increasing HOTS in the use of E-LKS used pretest and posttest techniques with n-gain analysis. The results showed that the validity of the E-LKS on light materials and optical instruments class VIII was declared valid with a CVI score of 1.00 (very high validity) in terms of material and language aspects as well as media aspects. The results of teacher and student responses are in the positive category. The teacher's response to the E-LKS contains HOTS which is 96.97%, while the student response to the E-LKS contains HOTS which is 92.72% with the "achieved" category. In increasing HOTS students who use the E-LKS are included in the effective category on the results of the analysis with an n-gain score of 0.72. This shows that the E-LKS is easy to understand and effectively used by students and teachers during distance learning.

Analysis of VAK Learning Styles of VIII Grade Students in Science

2024-02-17T07:45:15+00:00

Science learning is a process that is intentionally designed to facilitate the process of learning science. Based on initial observations made by researchers, it is known that MTs Nahjatus Sholihin students have not understood their respective learning styles, so students have been unable to maximize them in the science learning process. This study aims to analyze the VAK (Visual, Auditorial, Kinesthetic) learning styles of VIII-grade students in science subjects at MTs Nahjatus Sholihin, Rembang Regency. This research is quantitative descriptive research. The subjects of this study were all VIII-grade students at MTs Nahjatus Sholihin, with a total of 86 students. This study used the total sampling technique. Data collection methods were carried out through observation, questionnaires, and documentation. Based on the results of observations, it is known that from each class VIII that was analyzed for learning styles, the highest percentage of students had a kinesthetic learning style, with a percentage of 45% in class VIIIA, 40% in class VIIIB, and 41% in class VIIIC, while the lowest percentage of students had a visual learning style with a percentage of 22% in class VIIIA, 29% in class VIIIB, and 28% in class VIIIC.
