Tracer study is a mechanism implemented by universities to track graduates to measure the relationship between educational goals and processes with the current condition of graduates. In addition, the results of the tracer study are also used as an assessment for higher education accreditation. For this reason, Department of Integrated Science, Faculty of Mathematics and Natural Sciences, Universitas Negeri Semarang has developed a website-based integrated tracer study system. The system development method used is the Waterfall Model which consists of Requirement Analysis, Design, Development, and Testing. From the results of testing conducted by information systems experts, the system being developed is very feasible both in terms of functionality and usability. The website-based online system can handle graduate data management, able to provide all information about graduates and an overview to the Departmental Council regarding the competitiveness of graduates in the world of work. It is hoped that the tracer study system that has been developed can be continued to see how the competitiveness of graduates in improving department management.

This study aims to analyse the critical thinking skills of prospective science teacher students during astronomy lectures by applying a Blended Project Based Learning model. This research is a type of descriptive research with a quantitative approach. The study population was all semester 4 science students of science at one of the state universities of educational staff in Central Java, Indonesia. Students’ critical thinking skills experience a very good change after working on the project. The results of the average score of critical thinking skills that have significance values with medium and high N-Gain criteria. It was concluded that the implementation of Blended Project Based Learning model on astronomy learning able to increase critical thinking skills.

This workshop aimed to prepare science teachers making advantages of technological advances by using Information and Communication Technology (ICT) to improve quality of learning process. With the COVID-19 pandemic that occurred suddenly, science teachers were strongly encouraged to use of LMS (Learning Management System). Research method selected were descriptive quantitative to describe a phenomenon, event, and incident that occur factually and accurately of science learning quality during the outbreak. There were 25 participants involved. This research applied percentage descriptive analysis to examine whether participants successfully in designing LMS that meet minimum criteria. The results of interviews and questionnaires distributed before workshop showed that more than 50% of the trainee teachers only used Whatsapp to carry out online learning in the last semester. Some teachers also don’t know the characteristics of LMS, so they think that Whatsapp is also one of the LMS. Workshop done online via zoom meeting, divided into three meetings. Online consultation was provided as well to monitor teachers’ progress in designing LMS content. After workshop implementation, 88% of the participants were proficient in making LMS, they were able to filled it with learning activities such as discussions, presentation materials, and evaluation.

The purpose of this study was to developing an innovative thematic module on basic physics course and improving students’ logical thinking ability especially in the subject of Basic Physics II. The assessment developed in this study is an inquiry-based assessment to determine the ability to think logically by the students in learning science theme "light and vision." The research’s results and discussions are a module on the theme of light and vision developed by the eligibility requirements in very decent achievement category. The results showed that 56.66% students are in the stage of formal thinking, capable of abstract thinking and can analyze the problem scientifically and then resolve the issue, to acquire knowledge based on logical reasoning. The implementation of an innovative thematic module can improve students’ logical thinking ability.
