Abstract

The purpose of this study was to determine the development of a valid, practical and effective Problem Posing Modelas a learning tool. This research and development study (R&D) with 4-D have some phases, namely: define, design, develop, and desiminate. The data collection technique used test (description/essay) and non-test (tool validation and questionnaire). The data were analyzed through validity analysis, practicality analysis, and effectiveness analysis. The instruments used in this study were questionnaires,validation sheets, Lesson Plan, student’s worksheets, and test. The study showed that lesson plan is stated to be very valid with an average score of 90.15 in the k > 80 category andstudent’s worksheets is declared very valid with an average score of 84.58 in the k > 80 category. The students and teachers’ response are stated to be very practical with the average score of 80.55 in the k > 80 category. Besides, the effectiveness is declared effective seen from the students’ learning outcomes with 72% in the 60 ≤ p < 80 category. Thus, it can be concluded that the learning tool developed, Problem Posing Model is declared valid, practical and effective so that it can be used in learning mathematics.

Abstract

This research aims to describe the representation translation process in solving linear programming problems. The representation translation process will be explained at each stage of problem-solving according to Polya. The types of representation that will be explained are algebraic, numerical, graphic, and verbal. This research uses a descriptive qualitative approach. The research subjects consisted of two mathematics education students taking linear programming courses. Both subjects are students with high mathematical abilities who have good communication skills so that researchers can explore more in-depth information about the representation translation process. The instrument in this research is a linear program test which consists of two problems. The research results showed that subject 1 (S1) and subject 2 (S2) fulfilled three stages of problem-solving, namely understanding the problem, making a plan, and implementing the plan. Both subjects used all four representations in solving problems. The translation process that occurs starts with exploring sources, compiling initial knowledge, building targets, and determining suitability.

Abstract

The study conducted quantitative research using a True Experimental Design approach known as Pretest-Posttest Control Group Design, involving all grade X students of Senior High School. Cluster Random Sampling was used to select the experimental and control classes. Normality and variant homogeneity tests were conducted. Data analysis utilized a 5% significance level and paired sample t-test for hypothesis testing. Results indicated the REACT strategy effectively improved students' higher-order thinking skills. In the control class, a significant difference was found between pre-test and post-test scores, as well as in the experimental class. Observation sheet assessments showed an average score of 87.5, confirming successful application of the REACT strategy in the learning process. Therefore, the analysis demonstrates the superiority of the REACT strategy over conventional methods in enhancing the higher-order thinking skills of grade X students at Senior High School.

Abstract

This research aims to identify students' statistical literacy abilities, and this type of research is descriptive qualitative. The subjects in this research consisted of 24 Sociology Education students from Muhammadiyah University of Kupang taking statistics courses in the 2023/2024 academic year. The instrument used is an assignment consisting of 2 questions. Data analysis was done by analyzing students' answer documents to complete the assignments given. Students' statistical literacy abilities are identified using five statistical literacy competencies: understanding statistical concepts, insight into the application of statistical concepts, calculation and graphing skills, interpretation abilities, and visualization and communication skills. The research results show that more than 50% of students can fulfill statistical literacy competencies such as understanding statistical concepts, numeracy, interpretation, and communication skills. However, less than 50% of students do not meet competency in insight into the application of statistical concepts and visualization skills. Students' abilities in essential statistical literacy competencies still need to be improved because most students still have limitations in these competencies.
