This study aims to look at the effect of science process skills on Jambi City Junior High School students' critical thinking ability on the density and reflection of the material in the mirror. This research method used was mixed method, while the design used was sequential explanatory. The study was conducted at Adhyaksa 1 Junior High School in Jambi City and Al-Jauharen Islamic junior high school in Jambi. The sampling technique used was cluster sampling, so that the sample of this study amounted to 58 students. The data collection instrument consisted of an observation sheet of science process skills, a test of critical thinking skills, and an interview. Data were analyzed using descriptive statistics and inferential statistics. Based on the results of the linear regression test that has been carried out, the t value is greater than the t table, it can be said that there is a significant influence between science process skills and critical thinking skills on the density material and the reflection on the mirror.<strong> </strong>Students who have low process skills will tend to have low critical thinking skills. Low science process skills and students' thinking abilities lead to low student learning outcomes.

Teachers need to know how science process skills and students' critical thinking skills are. This study aims to see the relationship between science process skills and critical thinking skills so that teachers can determine the appropriate learning methods to improve science process skills and critical thinking skills. The researcher employed a sample of 58 students from class IX junior high school Adhyaksa 1 Jambi City. The sampling technique in this study using cluster sampling. This study's research design is an associative quantitative research method with a correlational research design. Quantitative analysis uses the SPSS program to find descriptive, normality tests, linearity tests, and correlation tests. The results showed that the significance value obtained was less than 0.05. It was seen that there was a relationship between students' process skills and students' critical thinking abilities

Purpose of study: This study was conducted to determine the science process skills of physics education students for refraction material on a concave lens. The questions discussed in this study are to describe the basic and integrated science process skills of Jambi University physics education students, what are the obstacles faced when the implementation of the e-module basic physics practicum II is applied, what are the solutions to the obstacles faced. Methodology: This study uses a quantitative approach with descriptive methods. This research was conducted in the Physics Education Laboratory of the Teacher Training and Education Faculty, Jambi University. The sample l in this study were 40 physics education students contracting basic physics II subjects. The sampling technique used in this study was a total sampling technique. Main findings: With the use of a Manual for Basic Physics 1 practicum in the form of e-module, it can improve students' science process skills. It can be seen from the research results, that the science process skills of physics education students at Jambi University on refraction practicum material on concave lenses Novelty/Originality of this study: With this research, students are motivated to improve science process skills so that they become more active and more familiar with the concept of learning and can improve learning outcomes. Through this research, students can become more innovative and creative teachers, and can also find out the extent of students' science process skills.
