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%.
