Abstract

This study aims to develop learning media, indicators, and indicators of whether student learning outcomes use webblog learning media developed on chemical bonding material that is higher than the predetermined KKM value. This research is a research development or Research and Development (R&D). By using the ADDIE development model (Analyze, Design, Development, Implementation, Evaluation). The sample used in this study were students of class X MIA 1 at SMA Negeri 8 Medan using purposive sampling technique. From the results of the analysis, the media developed by webblog learning. Results The results by the lecturers obtained an average feasibility of 90%, and an average score of material experts was 95%. Thus the learning media developed is valid and very suitable for use as learning media. The learning media developed were then tested on students to see students' chemistry learning outcomes. Testing was carried out using 1 experimental class which was carried out with webblog learning media. The hypothesis test shows that the average student learning outcomes of the experimental class are 78.29 with a minimum completeness criteria (KKM) 75. Based on statistical analysis at the 5% significance level it can be stated that the student learning outcomes using the developed webblog media are higher than the KKM values that have been set.

Abstract

The background of this research is that the world of education is currently intensively developing scientific literacy skills for students. This condition is the result of the rapid development of science and technology (IPTEK), so students must be able to act wisely and be able to adapt to science, environment, society, and technology. The purpose of this study was to determine the level of scientific literacy in nominal, functional, conceptual, and multidimensional aspects of class XI students on buffer solution material at State Senior High School (SMAN) 1 Binjai, Langkat Regency. This research method is a survey research, using a cross-sectional survey design. The sample in this study was taken from class XI IPA 1, totaling 30 people based on a purposive sampling technique. The research instrument used was a scientific literacy test in the form of essay questions, with indicators of scientific literacy referring to the theoretical framework. Based on the results of data analysis, it was found that the average value of students' scientific literacy abilities, nominal literacy indicators were 83.33%, functional indicators were 57.67%, conceptual indicators were 59.07%, and multidimensional indicators were 28.49%.

Abstract

The 2013 Curriculum System requires students to play an active role in the learning process at school and study independently. So it is necessary to have learning media that can help students understand chemistry learning. Chemistry is a natural science that is both a product and a concept so that learning can be done through practicum activities. Practicum activities require a device as a guide in scientific work called a practical guidebook. This study uses a qualitative descriptive approach, which describes descriptively the results of the analysis carried out. The stages are as follows: the interview stage was conducted with Chemistry subject teachers to obtain data in the form of the use of practicum instructions that have been used so far and hopes for improvement. The second stage of the analysis was carried out using a questionnaire given to students to see how the practicum teaching and learning process was doing at school so far. This research involved students of class XI IPA Al-Azhar Private High School Medan. Based on the results of the research and discussion that have been described, it is concluded that the chemistry practicum guide that has been used so far at Madrasah Aliyah Al Washliyah Kedaisianam has not met the criteria. In the implementation of chemistry practicum students have not used a special practicum module, but only used the modules available in the package book

Abstract

Learning media is one way to improve student learning outcomes. The Ferris wheel is one of these media that has many varied questions. It is hoped that the Ferris wheel-assisted TGT model will not only be innovative learning, but can also influence student learning outcomes. The purpose of this study is to determine the impact of the Teams Games Tournament (TGT) learning model on students' cognitive learning outcomes for the buffer solution using the Ferris wheel. A quasi-experimental design with non-equivalent groups and the posttest alone design approach is the research methodology used. Purposive sampling was employed during the sample process. All 294 students in class XI Mathematics and Natural Sciences at State High School 1 Lhokseumawe in the academic year 2022–2023 made up the population of this study. with a 50-student research sample. ways for gathering data, including tests, interviews, and observation. The research questions are evaluated with a school that is similar to the research location before being used in the study. The difficulty of the problems being examined, the discriminatory capacity, the validity, and the dependability of the tests are all taken into consideration. The outcomes revealed a sizable distinction between the Experiment I class and the Experiment II class. Cognitive ability as measured by the experimental class I average of 85.37 and experimental class II average of 79.58. If the value of sig 0.05, then Ha is acceptable. Cognitive findings sig. (2-tailed) t-test for equality of means on equal variances is assumed to be 0.008. The material for the buffer solution for class XI MIA was found to have a good impact on student learning outcomes when the TGT model using the Ferris wheel was used SMA Negeri 1 Lhokseumawe

Abstract

This study aims to analyze the phenomenon of intimate clothing with tight designs among UINSU female students, as well as the factors that influence their understanding of Islamic clothing. Using a qualitative approach with observation, interview, and documentation techniques, this study revealed that many female students understand Islamic clothing as an obligation to cover their intimate parts without considering aspects of modesty. The influence of social media and modern fashion trends also play a major role in shaping their clothing style. This study concludes that a deeper understanding of the values of Islamic dress is needed to maintain a balance between religiosity and modernity.
