Practicum activity is a scientific process to find out a phenomenon or validate a concept. HOT-LAB in laboratory activities is useful in improving 4C skills, including Critical Thinking Skills. The number of Modules or E-Modules that use a cookbook of guided laboratory inquiries was less to increase the 4C Skills in supporting the 21st Century skills. This study aimed to design, create and find out the effect of using HOT-LAB-based E-Modules to improve the students’ Critical Thinking Skills. The research method was the ADDIE RnD. Invalidation stage, E-Module that was validated by material and media validators, stated effective, so it was feasible to continue to data collection of students. Data of Critical Thinking Skills used 30 students as subjects whose raw data was analyzed using statistical tests. E-Module obtained a validity score of 83.33% on the material validation and 84.6% on the media validation. Moreover, the statistical test showed that there is a significant change in implementing E-Module, which means that the HOT-LAB-based E-Module improved the students' Critical Thinking Skills.

ABSTRACTThis research is aimed to know the differences increase critical thinking skills through learning group and individual problem solving in thermochemical material. This research uses a quasi-experimental design with nonequivalent control group design and study sample consisted of 103 students, divided into the first experimental (group problem solving) (35 students), the two group experimental (individual problem solving) (34 students). The collected through pretest-posttest. The analyzed with the Kruskal Wallis test, the results showed that the learning problem solving as a group or individually can improve students’ critical thinking skills. Statistical test there are significant differences in the students critical thinking skills thermochemical material between students who received group and individual problem solving. Critical thinking skills improvement with problem solving individual learning higher compared with group learning problem solving.Keywords: problem solving learning, critical thinking skillsABSTRAKPenelitian ini bertujuan untuk mengetahui perbedaan peningkatan keterampilan berpikir kritis siswa melalui pembelajaran group dan individual problem solving pada materi termokimia.

This research is motivated by the competence of teachers in preparing poor learning outcomes tests and has not been able to measure high-level thinking skills, especially critical thinking skills. Therefore the researcher seeks to improve teacher competence in compiling tests on student learning outcomes based on critical thinking skills through academic supervision. This study uses a school action research design that has stages of planning, implementation, observation, and reflection. This research was conducted for 2 months starting April 9 to May 17, 2019 for Physics teachers in the 7 target schools. Data is sourced from interviews with teachers and test documents prepared by the teacher. Data collection techniques include observation, interviews and documentation. Data analysis through the stages of data collection, data simplification, data presentation, conclusion drawing. Data were analyzed using assessment rubrics adjusted to indicators of critical thinking skills. The results of this study conclude that teacher competence in preparing tests of learning outcomes based on critical thinking skills has increased from the first cycle with a percentage of 61% with sufficient categories to 76% with good categories in cycle II.

During the Covid-19 pandemic that swept the world including Indonesia, and to improve students' critical thinking skills, it is necessary to have supporting media in the learning process as an edutainment website. This study intends to determine the validity of the edutainment website developed in physics lessons to improve student's critical thinking skills. The research method used is development research with the DDD-E model. This research was only limited to media development, and no practicality and effectiveness tests were carried out. In this study, the validity data were obtained from the results of validation by expert and were analyzed by descriptive quantitative using the category of Likert scale percentage. If the percentage of each aspect is ≥ 61%, then the edutainment website developed can be declared valid. The results of this study are the percentage of validity in the learning aspect of 90.30%, the material aspect of 90.56%, the media aspect of 88.65%, and the critical thinking aspect of 84.70%. Based on this, it can be concluded that the edutainment website is very valid so that it can be used as a physics learning media to improve students' critical thinking skills. The edutainment website can be an alternative learning media by utilizing information technology and hopefully in further research, it can apply edutainment website and perform practicality and effectiveness tests for learning both in class and distance learning

This study aimed to investigate the relationships between teachers' knowledge, beliefs and activities about critical thinking. . The study followed the descriptive approach. This research was based on a questionnaire designed to investigate English teachers' points of view about critical thinking for primary and secondary schools in Qasabet Al Mafraq which is a city in the north of Jordan The population of the study is 280 female and male teachers distributed through 160 primary and secondary school. The study sample was randomly selected and it represents 46% of all English teachers in Qasbet Al Mafraq. They are 40 male and 88 female teachers during the second semester 2018/2019. The results of the study indicate that most of the teachers know the higher and lower –order of critical thinking skills. Also, they are inclined to use the critical thinking strategy to achieve certain outcomes in the curriculum. According to the teachers' beliefs, they think critical thinking is an important and effective strategy for problem solving and decision making. On one hand, there is a positive correlation between teacher's knowledge, teachers' belief and critical thinking activitie such as role- playing, asking questions, problem- solving, conceptual maps, debate and game playing. But on the other hand, there are no statistically significant differences at (a= 0.05) due to the variables of gender, experience, number of students, and the stage they are teaching. The researcher recommends that more research should be done on the effect of critical thinking on the four skills reading, writing, speaking and listening.
