Creative thinking skills are recognised 21 century skills. This study aimed to determine whether students' creative thinking skills in biochemistry courses are improved through scaffolding-based problem-based learning. The study employed a mixed methods approach with a sample of 113 chemistry education programme students at Jambi University. An observation sheet instrument was used to gauge students' creative thinking skills during learning, test questions were used to gauge them after the implementation of Problem Based-learning, and an interview instrument was used to see how students responded once PBL learning had been implemented. Descriptive statistical testing techniques were applied to data between classes. It was found that there were significant differences in students' creative thinking skills after scaffolding-based PBL learning had been carried out. The biochemistry learning process was found to be conducive to scaffolding in problem-based learning. Providing scaffolding in problem-based learning also has a positive impact on students because this study proves that students become more active learners in education because the problem-solving process requires students to express opinions and exchange ideas.

This study aims to examine ICT competencies, research competencies, and teacher professionalism. The research method used is a mixed method. This study was conducted on urban and rural residents. The instruments used are teacher competency questionnaires, research competency questionnaires, questionnaires that measure teacher professionalism and interview instruments. Based on the results of data analysis, it is known that there is a relationship between teacher professionalism, ICT competence and research competence. This finding is that there is a relationship between ICT competence and research competence simultaneously on teacher professionalism.

Constructing student's scientific literacy is still a challenge for the developing country. PISA 2015 report on scientific literacy showed that Indonesia was positioned at 62th out of 70 countries. According to this result, the students are only able to explain the simple science phenomenon because some learning activities have not followed good scientific inquiry as a fundamental aspect of the nature of science. To overcome the problem, PISA 2015 stated that teachers are suggested to design well-structured laboratory activities that make actual scientific concepts and ideas, and help students make the connection among the hands-on activities, scientific ideas and real-life problems. Moreover, the student's conception of the nature of scientific knowledge is required to help a student become a scientifically literate person. This work aims to construct science knowledge and contextual problems to support students' conception of the nature of science. In the case of the physics subject, eight new heat and temperature experiment designs are proposed to construct students' scientific literacy in high schools. The aspects of scientific literacy on experiment designs are developed based on PISA 2015 frameworks.
