Abstract

The urgency of this research is that the implementation of differentiated learning is important because it encourages the development of critical problem-solving skills at the Elementary School level. Through this approach, each student can receive learning that is appropriate to their ability level, allowing them to actively participate in collaborative science and technology projects. The purpose of this study was to determine the implementation of differentiated learning in improving problem-solving skills in collaborative science and technology-based projects for elementary school students. The method used in this study is a mixed method with a Sequential Exploratory design. Sequential Explanatory research is a type of quantitative-qualitative research design that combines both approaches in two consecutive phases. The first phase is the collection and analysis of quantitative data, followed by the collection and analysis of qualitative data to explain the findings of the first phase. The population used in this study were all 5th grade students of Rejodadi Elementary School. The sample used in this study was 29 students of Rejodadi Elementary School and 1 teacher. The research instruments used in this study were test instruments, observation instruments, and interview instruments. The data collection techniques used in this study were tests with objective test types, observations to observe the learning process directly and interviews to dig deeper into the views of the research subjects. The data analysis techniques in the study were descriptive quantitative data analysis and descriptive qualitative data analysis. The results of the study in the implementation of differentiated learning in elementary school students' collaborative science and technology projects showed that teachers succeeded in designing projects that accommodated students' needs well with a differentiated learning approach, through the division of roles based on individual abilities, which allowed each student to contribute according to their understanding of the cognitive level accompanied by science and technology-based project learning, and the results showed that the ability to understand problems got the highest results for students compared to the ability to plan problems, solve problems, and recheck. By designing science and technology projects that are more responsive to students' needs, it is hoped that students' involvement and problem-solving abilities can increase, as well as encourage more effective and comprehensive learning in the classroom.

Abstract

This study aims to examine the effectiveness of the use of LKPD containing Character education based on Group Investigation in mathematics learning in terms of student learning outcomes. The study is a quasi-experimental study with a pretest-posttest control group design. In this design, two groups of students (experimental group and control group) were measured for their learning outcomes on flat shape material, before and after treatment was given. The study population was grade VII students of SMP Negeri 7 Bandar Lampung. Data analysis of the results of this study used the t-test, with analysis prerequisites in the form of normality and homogeneity of variance tests. The results of the normality test with Kolmogorov-Smirnov showed a p value = 0.200 which is greater than 0.05, meaning that the data is normally distributed and the results of the homogeneity test with Levene's Test obtained a p value = 0.711 greater than 0.05, which means that the variance between groups is homogeneous. The results of the independent t-test for the comparison between the experimental group and the control group on the posttest using SPSS showed that the p-value = 0.000 which is smaller than 0.05, meaning that there is a significant difference between the mathematics learning outcomes of students in the experimental group using LKPD containing Character education based on Group Investigation and the control group. The average mathematics learning outcomes of the experimental group were 85, while the control group was only 74. This shows that the use of LKPD containing Character education based on Group Investigation is effective in mathematics learning in terms of students' mathematics learning outcomes on flat shape material.

Abstract

Learning from the obstacles faced by other universities whose nature is administrative wise, currently questions still arise regarding the implementation of MBKM, which is about how the abilities will be developed by students who take part in the MBKM program, especially their hard skills, Reflective Abstractions. This research aims to determine the Reflective Abstractions (RA) of Students who carry out MBKM program and the factors that cause the obstacles in implementing MBKM. This research used a phenomenology method involving 6 students participating in the MBKM Mathematics Education study program. There was 1 student participating in the MBKM PMM scheme, 4 students participating in the Kampus Mengajar scheme, 1 student participating in the KKN Tematik scheme. The research results were analyzed qualitatively in four steps. This research resulted in all levels of reflective abstractions possessed by MBKM student participants. Starting from level 1, recognition; level 2, representation; level 3, structural abstraction; and level 4, structural awareness. However, not all subjects reach the level 4 of reflective abstractions and not all subjects have consistent reflective abstractions. In certain circumstances, they are facing problems that they have yet to understand from adapting MBKM activities, causing them to be unable to develop the new concepts.

Abstract

This study aims to describe students' mathematical problem-solving abilities in solving open-ended problems related to the topic of circles, based on their learning interest. The research employs a descriptive qualitative approach, involving junior high school students from SMP Negeri 14 Kota Jambi, categorized into high, medium, and low levels of learning interest. Data were collected through questionnaires to measure students' learning interest, tests to assess problem-solving abilities, and interviews for in-depth exploration. The findings reveal that students with high learning interest successfully demonstrated all indicators of problem-solving ability, including understanding the problem, planning a solution, executing the plan, and re-checking the results. Students with medium learning interest faced difficulties in calculation and were unable to re-check their solutions. Meanwhile, students with low learning interest struggled to plan solutions, resulting in an inability to solve problems or verify their answers. These results highlight the critical role of learning interest in enhancing students' problem-solving abilities in mathematics, particularly in addressing open-ended problems.

Abstract

The study explored teachers' perceptions of the challenges that affect mathematics instruction in the intermediate phase schools in the Chris Hani District. The study aims to explore teachers' perspectives on the challenges of mathematics instruction in the intermediate phase schools in South Africa. This study is important because it focuses on the personal and contextual factors that hinder effective mathematics teaching. The study seeks to understand teachers' perceptions and contextual factors that affect the effective teaching of mathematics in intermediate-phase schools to provide interventions. A qualitative approach with a phenomenology design was used to explore the objective of the study. The phenomenology design focused on understanding the lived experiences of the participants and their cultural and social contexts. The study used purposive sampling to select 8 participants with significant experience in teaching in the intermediate phase schools. The study found semi-structured interviews useful in collecting data because they blend flexibility and open-ended questions to gain insight. Thematic data analysis was used to analyse themes and patterns that emerged within the collected data. A major result was the inability of teachers to address the individual needs of students. In addition, teachers expressed concern about the curriculum expectations and the need for reforms. This study shows that, given the necessary support, they can improve mathematics teaching. However, the challenges to mathematics teaching suggest the need for the implementation of measures to improve mathematics teaching. Recommendations of the study include the need for teacher development in mathematics education and the need for education authorities to embark on curriculum reforms to address teachers' concerns regarding workload. In addition to improving mathematics teaching, policymakers prioritise educational reforms to address systemic challenges that affect mathematics instruction. This study contributes to understanding the challenges that affect mathematics teaching.

Abstract

Contextual problems play an important role as a medium for students to apply mathematical concepts. However, many students still have difficulty in understanding and interpreting the problem. Therefore, this study aims to describe the perceived of students' logical mathematical intelligence in solving contextual problems based on the mathematical literacy process. This study is a descriptive qualitative study. The research was conducted at Batu City Junior High School with 31 respondents. There were three research subjects representing the level of perceived of logical mathematical intelligence. The research instruments consisted of a questionnaire on the perceived of logical mathematical intelligence, a logical mathematical intelligence test, and an interview guideline. The data obtained were analyzed using the triangulation method. The results of the study showed that students' mathematical literacy with high perceived of logical mathematical intelligence met the employ, interpret and some formulate indicators. Then the mathematical literacy of students with moderate perceived of logical mathematical intelligence met the formulate, employ and some interpret indicators. In addition, the mathematical literacy of students with low perceived of logical mathematical intelligence only met some of the formulate and employ indicators. The findings of this study contribute to providing information and reflection materials for teachers in planning learning as an effort to improve mathematical literacy based on the perceived of students' logical mathematical intelligence.
