Abstract

One of the important things to note in supporting the success of learning is self-confidence and creativity. The purpose of this study was to determine the effect of self-confidence on mathematical creativity. This type of research is quantitative research. Through the use of random sampling techniques, the sample for this study was 65 semester 1 student in the mathematics education study program at the Islamic University of Malang. The data collected in this study is the result of a questionnaire about students' self-confidence and mathematical creativity. The questionnaire used in this study has met the validity and reliability. Questionnaire results were analyzed by correlation test and linear regression test. Correlation and linear regression tests were carried out with the help of SPSS. The results of the research show that there is a correlation between self-confidence and mathematical creativity. The results also show that self-confidence has a positive effect on mathematical creativity by 32.5%. This influence is due to four things, namely self-confidence in solving math problems (even though it is difficult), confidence in expressing opinions during discussions, confidence when appearing in front of the class, and confidence when answering questions from the teacher. Thus, it is important to train students to be more confident in solving math problems, so that this will increase their creativity in solving math problems.

Abstract

This study was motivated by the low learning outcomes of students in learning mathematics caused by the diverse characters of students, especially in the aspect of students' initial mathematical abilities. This study aims to improve students' learning outcomes in learning mathematics by using process differentiation based on students' initial abilities. The method used in this research is classroom action research (CAR). The research procedure followed the Kemmis & Taggart model, namely planning, action, observation, and reflection which was carried out in 2 cycles. The research subjects were students of class VIII.1 SMP Negeri 29 Bulukumba totaling 21 people, students of class VIII.1 SMP Negeri 10 Parepare totaling 32 people and students of class VIII.5 SMP Negeri 1 Mattiro Bulu totaling 26 people. The collection technique in this study was done through a learning outcome test. The results of research using process differentiation based on the initial ability of students showed an increase in learning outcomes. Based on the results of the research obtained the results of the actions provided, namely in cycle I students experienced an increase in learning outcomes compared to pre-cycle learning outcomes. However, because it has not met the standard of success, namely classical completeness reaching 85% of the students present, the provision of action is continued in cycle II. Then in cycle II students again experienced an increase in learning outcomes from cycle I and had achieved completeness of more than 85% of the students present. Based on the results of the research and discussion, it can be concluded that the application of differentiated learning process based on the initial mathematics ability of students carried out in the even semester of the 2022/2023 school year in three different schools located in South Sulawesi, namely SMP Negeri 29 Bulukumba (subject A), SMP Negeri 10 Parepare (subject B) and SMP Negeri 1 Mattiro Bulu (subject C) can improve students' mathematics learning outcomes.

Abstract

The rise of digital data theft makes researchers try to find better methods for digital data protection. Confidential digital data can be secured by encryption methods, one of which is the chaos function. We propose in this paper a new chaos function which is a composition of MS Map and Circle Map functions. This function has chaotic nature and is named the MS Circle Map. The sensitivity and randomness tests of the MS Circle map function are carried out using a bifurcation diagram, Lyapunov Exponent, and NIST. The analysis result of the bifurcation diagram shows that the MS Circle map has a good density at the value of r E (0,4). Besides that, the Lyapunov Exponent has a non-negative value at r E [0.4, 4], X0 = 0.9, r = 3.8, W = 0.5 λ = 2.1 which is the domain Xn E (0, 1) and parameter values r, E, and Ω, K are any real numbers. The results of the NIST randomness level test show that the MSC Map function all passed the randomness test of 16 NIST tests.

Abstract

There are various strategies for solving realistic HOTS-type problems, one of which is the intelligent guess and test strategy. However, students have not yet fully understood the use of this strategy. Therefore, this study aims to analyze the use of the intelligent guess and test strategy in solving realistic HOTS-type problems. This research employs a qualitative approach with a case study type. The study was conducted at SMP Widiatmika in Badung Regency, Bali Province, involving 27 eighth-grade students. Data collection techniques included tests and documentation. Data analysis employed qualitative content analysis, thematic coding, constant comparative analysis, and narrative analysis. The results of this study indicate that 96.3% of students chose to solve problems using an arithmetic approach, while 3.7% used an algebraic approach. The study also revealed that students faced difficulties in solving realistic HOTS-type problems, particularly in understanding the problems and determining the methods to use. Furthermore, the study identified three patterns in the use of the intelligent guess and test strategy: incomplete, complete but indirect, and complete and direct. The incomplete pattern occurs when students determine a formula without a strong basis to arrive at the final answer to a problem. The second pattern, complete but indirect, begins after the student understands the problem and makes the most reasonable guess, followed by testing. The student then analyzes the test results and makes the next guess based on the initial guess. This process is carried out cyclically until the student finds the most accurate guess. The third pattern, complete and direct, occurs when the student makes a direct guess because they fully understand the problem and have considered various aspects of the issue. The student tests the first guess and obtains the expected result.

Abstract

This study analyzes the sequence of tasks in the Mathematics textbook to identify learning obstacles associated with the concept of translation, with a specific focus on the definition of translation. This analysis employs the theory of praxeology, a key concept in the Anthropological Theory of Didactics (ATD). The findings highlight three potential didactical obstacles and one potential epistemological obstacle within the task sequence. Therefore, these findings should be considered by teachers to anticipate and minimize potential obstacles in teaching the concept of translation.
