Abstract

Mathematical literacy is defined as the ability possessed by an individual in formulating, employing, and interpreting mathematics in a variety of contexts. This research aims to describe the mathematical literacy processes of Junior High School students in solving PISA-like problems on space and shape content. The method in this research used qualitative descriptive. The research subject was students of the ninth grade in SMP Negeri 2 Krembung on Sidoarjo, which consisted of twenty-nine students. The instruments used were test and interview. The results showed that the students’ mathematical literacy was classified as less for the process of formulating. Some students still find many difficulties, such as difficulty in determining the strategy used in solving the problem as well as errors in calculation and drawing conclusion. The students’ mathematical literacy was classified as quite good for the process of employing. Students understand the intent of the problem and know what strategy used, although there were some minor errors in calculation or drawing a conclusion. The students’ mathematical literacy was classified as very lacking in the process of interpreting. Students only guess because students were still unable to understand the meaning of the questions and what strategies were used to solve the given problems to answer questions.

Abstract

This study aims to improve students' critical thinking skills in mathematics learning using a problem posing approach. This study was classroom action research conducted over two cycles. Researchers use tests of critical thinking skills and observation sheets for data collection techniques. The subjects of this study were 35 grade 8 students of SMPN 2 Candi. Data analysis techniques use a combination of qualitative and quantitative. The results of the study showed that based on the results of the critical thinking skills test, there was a significant increase in the percentage of classical completeness from the pre-action stage to cycle 1, and there was a slight increase from cycle 1 to cycle 2. In the pre-action stage, there were 68.57% of students completed, where students are said to complete if their level of mastery is in the category of sufficient or above. In cycle 1, 80% of students completed, and in cycle 2 there were 82.86% of students completed. Based on the study results, it was concluded that students' critical thinking skills in mathematics learning have increased by applying the problem posing approach.
