Analysis Critical Thinking Stage of Eighth Grade in PBL-Scaffolding Setting To Solve Mathematical Problems

The purpose of this research was described critical thinking stage of students grade VIII in setting PBL and scaffolding to solve mathematics problems. Critical thinking stage consists of clarification, assesment, inference, and strategy/tactics. The subject were teo students in the level of capacity to think critical (uncritical, less critical, quite critical, and critical). So that this research subject was 8 students in VIII A One State Junior High School of Temanggung. The result showed a description (1) critical thinking stage of students in setting PBL, in clarification the higher level of capacity to think critical students, students can identification information from question fully, can identificatio problem became detailed, and can explored the relationship among the information; (2) a strategy of scaffolding were given by critical thinking stage and TKBK, in assesment, scaffolding had given was given hint/key classically; and (3) transformation characteristic of the critical thinking stage of students after given scaffolding, it because of habituation in setting PBL and scaffolding.

Enhancement of Lecturer Professionalism using Lesson Study Approach for Curriculum Review of Mathematics 1

The purpose of this research is to know the improvement of lecturer professionalism through the approach of lesson study, to see the increase of student interaction (with the students, teaching materials, lecturer), and to know whether the student learning result of the lesson study approach reaches the completeness. This research is a research of mixed method based on lesson study. Activities performed for each cycle consists of three stages: planning, execution, and reflection. The qualitative data is the description of the lectures professionality improvement with the quantitative is the increase of student interaction (with students, teaching materials, lecturers), and the result of studying Curriculum Review of Mathematics 1. The subject of this research was the students of Curriculum Review of Mathematics 1 in Mathematics Department UNNES year academic 2016/2017. The research instruments are a test, observation sheet, and questionnaire. The result of the research is the improvement of professionalism of lecturers of KBK Mathematics Education through lesson study approach for Mathematics Curriculum Mathematics 1 course, student interaction (with students, teaching materials, lecturers) increases, and learning achieves mastery.
