This study aims to determine the level of critical thinking skills and science motivation of students in learning science. The population in this study all students of class VIII SMP N 3 Pemalang were 10 classes with 317 students. The research sample was randomly selected with a sample of one class of 31 students. The study was conducted on January 4, 2020, data collection techniques in the form of tests and questionnaires. The test is used to determine students' critical thinking skills in learning science in simple plane materials. While the questionnaire is used to determine the level of science motivation of students in learning Natural Sciences. Descriptive quantitative data analysis and percentage. The results showed the level of critical thinking skills of Pemalang N 3 Middle School students was 35.48% from the high and medium category. While the level of science motivation of Pemalang N 3 Middle School students was 35.50% from the high and medium category.

The purpose of this research was to investigate “the effect of foreign language learning activities on critical thinking skills of 4th-grade students”. To achieve this purpose, researchers tried to answer these questions: (1) What is the effect of critical thinking activities on students’ critical thinking? (2) What is the effect of critical thinking activities on students’ personal definitions of critical thinking and critical thinker? (3) What is the effect of critical thinking activities on students’ social skills? The method of this research is action research which is considered highly important for educational sciences. In the course of this research, activities for developing critical thinking skills were implemented to 4th grade students. 25 4th grade private elementary school students participated in the research. Researchers used 13-question “Critical Thinking Skill Open-ended Questionnaire” to collect data. The answers given to the open-ended questionnaire before and after the activities were analyzed using content analysis, and themes and codes were determined accordingly, thereby answers of the students are compared. It is noted that before implementation, most of the students did not have any idea about critical thinking or they thought critical thinking has a negative connotation; however, after implementation, they gained more positive and open-minded opinions about this term.
