Abstract

This study aims to analyze and determine the effect of applying the contextual approach in improving the ability of calculation operations in students with learning delays. This study uses a quantitative approach with a single-subject experiment method, often called Single Subject Research (SSR), with an A-B-A design. The subject of this study is grade VIII students at SMP Islam Mandiri. The data collection technique in this study was carried out using observation and a test of computational operation ability. The results of the baseline-1 phase showed a stable score and increased when the treatment was carried out in the intervention phase; after the treatment was carried out, the research subjects were then given a test in the baseline-2 phase, and the results obtained increased with a score of 100 in each session. The percentage overlap of the three phases is at the level of 0%. Thus, the results show that applying the contextual approach positively improves the ability to calculate operations in students with learning delays.

Abstract

The application of instructional strategy must consider the characteristics and students' culture to get an optimal learning result. The Indonesian character is to be based on this strategy and not finish the task well if there is no compulsion or punishment. This character is a background of purpose tasks and forced instructional strategy. This strategy emphasised a routine task and a plan for the students, noticing the deadline for finishing the task and the punishment if the task is not finished well. This strategy can be an alternative strategy to increase learning quality, especially to develop the student's awareness about how studying is important for them.

Abstract

Mathematics plays a crucial role in the 21st century because it emphasises logical and systematic problem-solving processes. This research evaluated the implementation of 21st-century skills in general mathematics instruction and the mathematics performance of the Cebu Technological University San Francisco Campus students for the Academic Year 2022-2023. The study employed a descriptive-correlational research design, utilising researcher-modified questionnaires anchored from the P21 framework, which were pilot-tested, expert-reviewed, and validated. It involved 203 students and perceived a very satisfactory implementation of the 21st-century skills of critical thinking, communication, problem-solving, collaboration, and perseverance in general mathematics instruction. Also, it assessed the students' mathematics performance using a 30-item multiple choice test and found poor performance in all six topics. The study found a weak but statistically significant relationship between the implementation of 21st-century skills and mathematics performance. Among the skills, collaboration showed the strongest positive relationship with mathematics performance, followed by communication, perseverance, and critical thinking. Surprisingly, problem-solving did not demonstrate a significant relationship, suggesting that other factors may also influence performance. The findings emphasise the importance of these skills in improving mathematics performance and provide a foundation for the development of a contextualised self-learning module in general mathematics. Further research is recommended to validate these findings.

Abstract

Mobile applications like GeoGebra are crucial for learning algebraic function graphing among college students. This application provides interactive visual aids that improve comprehension and memory of complex ideas relating to graphing of algebraic functions. It aimed to determine the effects of GeoGebra software in smartphones on education students' attitudes, motivation, and performance in College Algebra at a technological state university in Cebu City, Philippines. The participants were 80 students [40 students in the control group and 40 in the experimental group] who were chosen using purposive sampling. The quasi-experimental method used three questionnaires (Fennema-Sherman Mathematics Attitude Scales, Mathematics Motivation Questionnaire, and Students' Algebra Performance). The data were treated using frequency, mean, standard deviation, Pearson r, and paired t-test. The study revealed that students' attitudes and motivations toward algebra do not have significant relationships with their pretest and posttest performances in graphing algebraic functions. However, there is a substantial difference between the students' posttest means scores in Algebra of the control and experimental groups. The study concluded that students' attitudes toward algebra improved when using GeoGebra software to learn graphing of algebraic functions. The researcher recommends integrating GeoGebra software into Algebra's curriculum to enhance students' performance in graphing algebraic functions.
