Abstract

Mathematics learning can have an impact on the development of one's mindset in the learning environment. This process is obtained through teacher innovation which provides learning with various methods and approaches that are in line with what will be taught. Inductive-deductive is an approach that can help students' creative thinking processes and increase learning motivation. For this reason, this study wanted to see how effective and influential this approach is on the ability to think creatively and motivation to learn. The method used is a significant test using one sample t-test and one paired sample t-test. The results obtained are t-count values of 2.09 and 10.66 for the inductive-deductive class and -0.848 and -0.94 for the conventional class where the t-table value is 1.684. Whereas to see the effect of the approach obtained values of 6.149 and 6.344 with a t-table of 1.960. The value that is greater than the t-table states that the class is effective and has influence, so it can be concluded that the inductive-deductive approach is effective for critical thinking skills and learning motivation, while conventional classes are not used effectively. The inductive-deductive approach also influences students' creative thinking abilities and learning motivation.

Abstract

The limited usage and repurposing of media in education served as the driving force behind this study. Student Textbooks and Student Worksheets (LKPD) are designed to support instruction. Additionally, Systems of Two Variable Linear Equations (SPLDV) implicit graphical problem solutions are made possible with the use of GeoGebra media. In this inquiry, interactive learning tools for the SPLDV curriculum will be made using GeoGebra. The 4-D Thiagaradjan model serves as a model in this study on development. Define, design, develop, and deploy are the four stages. This experiment involved eighth-graders aged 14 and two eighth-grade math teachers. Utilizing a requirements analysis, interviews, and questionnaires, observational data was gathered. An study of the data collection process's demands, as well as interviews and surveys, are all included. Validity, practicability, and efficacy were three essential development conditions that had to be met before a study could be put into action. Proportion scores were validated by two qualified validators to support the study's conclusions. For learning device formats, graphics, language, and content validation, the average score is 3.78. (Applicable classifications). The effective category, which received an average score of 74.3 on the pretest and 87 on the posttest, the complete category, which served as a gauge of the teacher's capacity to manage learning and received an average score of 4.4 in the very good category, and the practical category, which also received an average score of 4.4 in the very good category, served as the foundation for the research findings. As a result, improving student performance can be accomplished through the development of learning tools based on realistic learning models.Keywords: Development of Learning Devices, Thiagaradjan 4-D Model, Realistic Mathematical Education (RME), Mathematical Literacy.

Abstract

This research aims: (1) to determine whether problem-based learning models improve mathematical problem-solving abilities and self-efficacy; (2) to explore the interaction between students' initial mathematical abilities and the learning model. The study employed a quasi-experimental quantitative design, with ANOVA used for inferential data analysis. Fifty eighth-grade students from SMP Negeri 3 Aek Kuo in the academic year 2022/2023 were examined. The null hypothesis (H0) was accepted, and the alternative hypothesis (Ha) was rejected since the significant F-test value was 0.178 > 0.05, and the T-test value was 0.692 > 0.05, indicating no significant difference in the average scores between experimental classes I and II. PBL students demonstrated better performance in answering mathematical problems compared to those in the direct learning group. Experimental class 1 achieved a mastery level of 84%, while experimental class 2 achieved a mastery level of 64%. PBL learners exhibited higher self-efficacy compared to those learning through direct instruction. Hypothesis testing indicated that students in experimental class 1 had stronger confidence in mathematical problem-solving compared to students in experimental class 2. The problem-based learning (PBL) methodology did not have a significant impact on students' mathematical problem-solving abilities. Hypothesis testing using interaction analysis yielded a significance value of 0.730 > 0.05. Both PBL and students' basic mathematical abilities influenced self-efficacy. Interaction analysis indicated a significance value of 0.000 < 0.05.Keywords: Problem based learning, early math skills, math solving, self efficacy

The instrument in this study is a formative test used to see the level of mathematical abstraction ability and the answer process given by students. The difficulties faced by students in the process of solving the problems given can be known through the interview process conducted and documented through cell phones. Of the 19 students who took the math abstraction ability test, 4 students had high category math abstraction ability (21%). 11 students have medium category math abstraction ability (58%), and 4 students have low category math abstraction ability (21%). Of the 4 problems given, for the recognition stage, problem no 1 can be solved by all students. problem no 2 can be solved by 17 students, problem no 3 can be solved by 12 students and problem no 4 can be solved by 8 students. The decline also occurred at the representation and structural abstraction stages. After being analyzed based on the process of answers given by students and the results of interviews conducted, the decline was caused by: 1. the level of difficulty of the problem, 2. learning experience, 3. reasoning power and 4. literacy skills of each different student.. In this research, the media used to help the research process is geogebra. The use of this media is only limited to how to solve the problems given in other ways besides the concepts taught at school.Keywords: Qualitative Research Analysis; Mathematical Abstraction Ability; Problem Based Learning Model
