Astronomy in front of students is known as part of science-based science that gives curiosity about the science of religion and technology. Mastery of Astronomy concept of teacher candidate is analysis with the aim to take a picture of mastery of concept and process of astronomy lecture which is a new course as the base of development of astronomy learning device based on KKNI. This research method is descriptive quantitative and qualitative. Technique of collecting data is done by triangulation through analysis of test result, astronomy lecture observation, and questionnaire response of physics teacher candidate. Data analysis technique is done descriptively. The results obtained that the results of the test document analysis obtained the test instrument subjects more dominant astronomy on aspects of concept understanding, no test items that measure the realm of analysis and creation. Analysis of test results obtained that the ability of the most dominant students in the realm of knowledge and the lowest ability in the realm of application. The results of observation suggest that astronomical learning is applied by lecture, discussion and assignment methods. Lecturers give lectures related to content, student discussions to discuss more in-depth Astronomy content and assignment to students to make logbook about celestial phenomena. The results of the student questionnaires give a positive response to astronomical learning that provides contextual knowledge in life.

This shows that the low understanding of the concept of pre-service teacher to the basic concepts of physics, causing misconception. Therefore, that misconceptions are define an information to develop a continuous research that can contribute to improving the quality of teachers’ candidates, especially physics teachers who will give a posit...

In this research, mapping of cognitive style, logical thinking ability, and conceptual knowledge of electrical and magnetism topics aimed to know the pattern of change of three variables owned by prospective physics teachers based on grade level. This study is descriptive research with 95 respondents taken from one class for each level by random sampling. The results showed that cognitive style, logical thinking ability, and conceptual knowledge variables changed with linear pattern. This finding becomes one of the next considerations to design electricity and magnetism learning assessment in universities.

Astronomy in front of students is known as part of science-based science that gives curiosity about the science of religion and technology. Mastery of Astronomy concept of teacher candidate is analysis with the aim to take a picture of mastery of concept and process of astronomy lecture which is a new course as the base of development of astronomy learning device based on KKNI. This research method is descriptive quantitative and qualitative. Technique of collecting data is done by triangulation through analysis of test result, astronomy lecture observation, and questionnaire response of physics teacher candidate. Data analysis technique is done descriptively. The results obtained that the results of the test document analysis obtained the test instrument subjects more dominant astronomy on aspects of concept understanding, no test items that measure the realm of analysis and creation. Analysis of test results obtained that the ability of the most dominant students in the realm of knowledge and the lowest ability in the realm of application. The results of observation suggest that astronomical learning is applied by lecture, discussion and assignment methods. Lecturers give lectures related to content, student discussions to discuss more in-depth Astronomy content and assignment to students to make logbook about celestial phenomena. The results of the student questionnaires give a positive response to astronomical learning that provides contextual knowledge in life.

Critical thinking is needed for students who are preparing to enter a complex working field.This study aims to determine the profile of critical thinking skills of pre-service physics teachers at the University of Flores. The method used is descriptive survey method. The result of the study shows that: 1) The students' critical thinking skills are spread in 5 categories, namely "very high" by 10%, "high" by 22.5%, "medium" by 32.5%, "low" by 10 % and "very low" 25%; 2) Students need to be familiarized with questions that stimulate critical thinking skills; 3) A physics-based thinking test tool is needed for critical students of pre-service physics teacher.

Analyzing argumentation is needed to investigated because students require to obtain it in order to become a better thinker and making the right decisions. The heat conductivity problem has been given to 20 preservice physics students who have been enrolled in the Introductory Physics I. The test has precisely analyzed in qualitative way. An analysis of collected data has mainly focused on student conclusion in heat conductivity problem. Based on data analysis, it can be concluded that students' critical thinking skills toward analyzing argumentation on heat conductivity concept is still poor category.
