Abstract

The aim of this study is to describe the effectiveness of using flipped classroom learning model on the ability to understand students' mathematical concepts on the topic Phytagoras theorem at the eighth grade students of SMP Negeri 8 Padangsidimpuan. The research was conducted by applying experimental method (one group pretest post test design) with 25 students as the sample and they were taken by using cluster sampling technique from 226 students. Observation and test were used in collecting the data. Based on descriptive analysis, it was found: (a) the average of using flipped classroom was 3.80 (good category) and (b) the average of the ability to understand students' mathematical concepts on the topic Phytagoras theorem before using AIR learning model was 68.00 (enough category) and after using AIR learning model was 87.00 (very good category). Furthermore, based on inferential statistic by using pair sample ttest, (SPSS version 22), the result showed the significant value was less than 0.05 (0.000<0.05). It means, using AIR was effective used on the ability to understand students' mathematical concepts on the topic Phytagoras theorem at the eighth grade students of SMP Negeri 8 Padangsidimpuan.

Abstract

This study aims to develop AMP (Authentic Mathematical Problems) that are valid, practical, effective, and know the characteristics of AMP to improve critical thinking ability. This study uses a Research Based Design approach with discussion and analysis of problems, planning, repetitive cycles, and reflection. AMP were implemented using the IKRAR learning model (Initiation, Construction-Reconstruction, Application, and Reflection) with effective questions. The trial was conducted at SD N 1 Ubud involving fifth grade students and a teacher. The validity data was collected by conducting expert tests that were adjusted to the validity assessment instruments components of AMP. The practicality data was collected through questionnaires and observation sheets in learning activities then analyzed descriptively. The effectiveness data was collected through critical thinking ability tests consisting of AMP. The characteristics data of AMP was collected based on studies, physical form, and findings during the trials. The results show that the AMP in IKRAR learning to improve critical thinking ability are valid, practical, and effective. The characteristics of AMP are based on real life problems, can measure critical thinking ability, encourage students to be interested in determining solutions, train students to think divergently, and do not use presupposition words (for example: if, suppose, etc).
