Published: May 2020

Abstract
The inquiry model is one of the learning models that have the potential to train students’ high-level skills and thinking. These activities require good initial knowledge of students. An advance organizer is one strategy that can be used to overcome this problem. The purpose of this study was to examine the effectiveness of the inquiry model with advanced organizers in improving students’ conceptual understanding. The research design used was a non-equivalent pretest and posttest group. The research subjects were divided into two groups, namely the experimental group and the control group. Data were analyzed by N-gain test. The results showed that the understanding of the concept of the experimental group was better than the control group. Thus it can be concluded that the inquiry model combined with an advanced organizer is effective in increasing mastery of students’ physics concepts. In general, the increase in the experimental group was higher than the control group both in the cognitive aspects and in each sub-material.

Abstract
In mathematics learning, students’ critical thinking ability is required to understand and solve mathematics problems that require reasoning, analysis, evaluation, and interpretation. Therefore, to describe students’ critical thinking ability, research was conducted on 30 students (15/16 years old) in West Java, Indonesia. This research is qualitative descriptive research and the data collection technique is written test with 3 description questions about trigonometric problems. The test results were analyzed using three indicators of critical thinking ability, (1) composing questions with reasons, (2) identifying relevant and irrelevant data of a mathematical problem, and (3) solving mathematical problems with reasons. The results showed that: (1) almost one-third of the number of students can compile the questions with the reasons, (2) more than one-third of students can identify the relevant and irrelevant data of a mathematical problem, and (3) more than one-third of students can solve the mathematical problems with reasons. The average percentage of students in trigonometric problems is 31,86%. Based on the research result, it is seen that most students do not have good critical thinking ability in solving trigonometric problems.
