Abstract

Science process skills have the potential to build students' basic competencies. There are many factors that influence this skill, one of which is the proper use of media. The development of excel-based practicum media is one of the solutions to solve this problem. The aim of the research is to improve students' science process skills in doing practicum. This study has a Research and Development (R&D) design with a population of 132 people with a sample of 66 people using a purposive sampling technique. includes media feasibility 0.72 or high, visual communication 0.35 or moderate, and material 0.45 or moderate. The reliability test obtained 0.000, which means that the similarity between the ratings given by the two validators is very low. In conclusion, the developed media meets the requirements to be used as a research instrument.

Abstract

It is important for students to comprehend the concepts as the ability not only to understand, but also to be able to apply the concepts given to solve a problem, and to think critically about the problems during the learning process. The purpose of this study was to determine the improvement differences of students' critical thinking skills after the application of the case method model learning based on character values ​​in the reproductive system material in SMA IT Al-Fityan and SMA IT Al-Arabiyah. The research method included quasi-experimental research with a pretest-posttest non-equivalent control group design with a sample of 116 students. Data collection techniques used was students' learning outcomes data by using pretest and posttest questions in the form of multiple choices with reasons. The questions were according to the indicators that must be achieved during learning process. Then the data was analyzed by using the average value of the pretest and posttest, then the average difference test was carried out. Hypothesis testing for students' critical thinking skills was analyzed by using = 0.05 with a significant level of 0.95% with the following test criteria: If tCount < tTable then Ho is accepted, and if tCount ≥ tTable then Ho is rejected. The study results in the findings that: 1) Improvement in students' critical thinking skills by applying case method learning models based on character values ​​in reproductive system materials; 2) The character value of students was greatly improved during learning process and when students are in the environment; 3) The relation between improving critical thinking skills and character values ​​in the learning process was excellent.
