Abstract

A person's creative thinking ability is graded and can be improved by understanding creative thinking ability and its factors such as self efficacy. The purpose of this study is to describe the level of creative thinking ability of ninth grade students with high, medium, and low self efficacy in solving mathematical modelling problems. This research uses a qualitative approach with descriptive research type. For the research subject, the researcher chose three ninth grade students at Junior High School 4 Pare with different levels of self efficacy (high, medium, low), high mathematical ability, and the same gender. The researcher used self efficacy questionnaire, mathematical ability test, mathematical modeling problem, and interview to collect data. Data in the form of test results were analyzed based on Siswono's level of creative thinking ability and follow-up interviews. The results showed that in the fluency aspect, high self efficacy students could give three correct answers, moderate self efficacy students could give two correct answers, and low self efficacy students only gave one correct answer. The flexibility aspect, the three subjects can provide solutions using different ways. The novelty aspect, high self efficacy students can provide two new solutions while moderate self efficacy students and low self efficacy students produce common solutions. Based on this, high self efficacy students belong to creative thinking ability level 4 (very creative), moderate self efficacy students belong to creative thinking ability level 3 (creative), and low self efficacy students belong to creative thinking ability level 2 (quite creative).

Abstract

The process of learning mathematics for some students can cause anxiety. The anxiety experienced by students can interfere with the mathematics learning process, especially in students' ability to solve mathematical problems. This study is qualitative descriptive research that aims to analyze problem-solving abilities in terms of mathematical anxiety. Researchers tested the ability to solve problems ill-structured on six grade VIII students of SMPN 1 Kemlagi in Mojokerto. The six students consisted of two students with high math anxiety, two students with moderate math anxiety, and two students with low math anxiety. The results of data analysis showed ill-structured problem-solving abilities (1) students with low and moderate anxiety levels were able to reach the stage of understanding problems, making plans, and re-examining very well; (2) students with low levels of mathematical anxiety have reached the stage of executing the plan very well, while students with moderate levels of mathematical anxiety have not reached this stage because there are still errors in making calculations; (3) students with high levels of math anxiety have not been able to reach all stages of problem-solving. This study suggests that teachers pay more attention that math anxiety as one of the factors that must be considered in mathematics learning

Abstract

In math learning, creative thinking is very important because it allows broad thinking to find new solutions to problems. This study aims to describe the level of students' creative thinking in solving ill-structured problems in the context of calorie intake. This type of research was descriptive with a qualitative approach. Researchers chose three students in class VIII with different mathematical abilities (high, medium, and low) based on their value as research subjects. To collect data, researchers used ill-structured problem tests and interviews. The data were analyzed based on the level of students' creative thinking and follow-up interviews. The results showed that in aspect fluency, S1 and S2 could give two correct answers, while S3 only gave one correct answer. Aspects of flexibility: S1 and S2 can provide alternative answers using different mathematical concepts, while S3 only provides one way of providing alternative answers. Aspects of originality: S1 can provide two unique solutions, while S2 and S3 produce ordinary solutions. Based on this, S1 is included in level 4 (very creative), S2 is included in level 3 (creative), and S3 is included in level 0 (not creative). Based on the results of this study, designed learning must stimulate students' creative thinking abilities, such as by providing problem-solving questions that allow students to solve them with various strategies.

Abstract

This study aims to describe the process and results of the development of STEM-Surrounding-Nature-Exploration (SNE) integrated with PjBL-based learning materials to improve students' creative thinking skills on sets concepts This is developmental research using the Plomp model to develop learning materials in the form of Teaching Modules and Project Worksheets for set materials with a STEM-SNE integrated project learning design. The trial was conducted on 31 grade 7 students at a junior high school in Surabaya, East Java. Data collection and analysis techniques were carried out using validation sheets to determine the validity of the learning materials tested on the validator. A pre-test and a post-test were used to measure effectiveness related to students' creative thinking on set material. In addition, student response sheets were also used to determine the practicality of the learning materials. Results found that the learning device obtained a validity criterion of 92.5% for the Project Worksheet while 91.25% for the validity of the Teaching Module and each was classified as very valid. For effectiveness criteria, it was obtained n-gain of 0.7512 in the limited trial and 0.71 in the class trial and each of them obtained high effectiveness criteria. Learning materials obtain very practical criteria implemented with an average student response acquisition of 85% and 84% for project learning designs.
