The observations and discussions with teachers who taught in Biology class III SD Negeri 1 Kampung Baru Lampung, it is known that the dominant learning more teachers using the conventional approach. Students also receive more information from the teacher so that students are less than optimal in empowering potential, including critical thinking skills. One effort that can help empower students in critical thinking skills is to use science process skills. The purpose of this study was to determine the effect of the use of science process skills for critical thinking skills of students in the subject matter of Characteristics and Needs of Living Things. The study design is a group pretest-posttest non-equivalent. The samples in this study were grade IIIA and IIIB were randomly selected by random sampling technique clusster. Data were obtained from the pretest and posttest at each meeting, the gain score is calculated by the formula. Data analysis using t-test at 5% level of belief using SPSS 17. The results of this study indicate that there is a significant effect of the use of science process skills for critical thinking skills of students in the subject matter of Characteristics and Needs of Living Things.

To ensure the success of science learning oriented to higher order thinking skills, especially scientific communication skills (SCS), valid and effective instruments are needed. The existing instruments, although helpful, are still too general and have not touched the socio-cultural context. Therefore, we developed an instrument to measure SCS according to the characteristics of students in Indonesia. This study tested the validity, reliability and assumptions of the hypothetical model of the scientific communication skills inventory (SCSI) instrument developed. This study involved 1,287 students in Indonesia. The test was carried out through confirmatory factor analysis with structural equation modelling (SEM) using AMOS version 21. The results of the analysis show that the reliability of the instrument based on Cronbach’s alpha coefficient is 0.720. The convergent validity test detected one item of the oral presentation indicator as invalid and the discriminant validity test confirmed that all instrument items were declared valid. The goodness of fit test shows all scores according to the recommended standard criteria so that SCSI can be used to identify the SCS ability profile of students in Indonesia. For further research, we recommend the development of a learning model that prioritizes the context of social issues to grow students’ SCS.

This essay's purpose is to provide a summary the perceptions of science teachers towards scaffolding learning programs with peer tutoring in improving scientific communication skills and HOTS. This research was conducted in the province of Lampung, Indonesia, involving 74 middle school science teacher respondents. A mixed method with a sequential explanatory design was used for the study. Data were collected through interviews and surveys, and descriptive analysis was used to analyse the results. The survey findings indicate that science instructors have a favourable opinion of using scaffolding in conjunction with peer tutoring. The analysis's findings indicate that most instructors have not used peer tutoring and scaffolding in the classroom to help students advance from their current competencies to potential competencies. In addition, teachers also have not implemented scaffolding learning programs with peer tutoring.
