Abstract

Students ability to solve mathematics problems, especially problem-solving questions, is still relatively low despite the 2013 curriculum requiring students to be able to solve such questions and expecting the learning process to apply a scientific approach. This learning process requires students to be more engaged and teachers to facilitate students experiencing difficulties during the learning process. However, teachers have a little knowledge of the difficulties experienced by students in the learning process because the learning process conducted in the classroom does not provide enough information concerning the students difficulties. Students self-assessment can help students in identifying their difficulties, and the teacher can choose the right strategies to overcome them. Therefore, it is necessary to develop learning instruments encouraging students to engage more in assessing their abilities which in turn improving their problem-solving abilities.This study aimed to develop and produce the valid, practical and effective self-assessment sheet and student worksheet to improve students problem-solving skills employing scientific approach. This study was development research referring to the Dick and Carey model. The learning instruments trials were conducted at one of the junior high schools in Banda Aceh. The results of the study found that the self-assessment sheet and student worksheet employing the scientific approach satisfied the criteria of being valid, practical and effective. Thus, teachers and students can use this self-assessment sheet and worksheet to improve the quality of learning in schools.

Abstract

The ability of representation is one of the important components to develop students' thinking skills, because this capability is instrumental in helping students to transform abstract ideas into real idea and it can train students to improve problem solving skills with a variety of forms including pictures, diagrams, mathematical expressions, or words or written text. One model of learning that increases the ability of the mathematical representation is a learning model of problem-based learning. This research aims to: 1) determine a mathematical representation increased ability of students taught with problem based learning models 2) the interaction between the learning model of problem-based learning and grouping of students to increase the ability of the mathematical representation. This research is a quantitative research with an experimental method, that has pretest-posttest group design. The population was all students of class X SMA UnggulPidie Jaya by samples of two classes, namely class X3 as an experimental class and class X2 as the control class. The data collection was done by using test. Then analyzed by t -test and ANOVA at the 0.05 significance level after testing prerequisites are met. Based on the analysis we can conclude that: 1) to improve the mathematical representation of students who applied learning model of problem based learning is better than an increase in the ability of the mathematical representation of students who received conventional learning. 2) there is no interaction between the learning model and grouping of students to increase the ability of mathematical representation.

Abstract

The learning process of mathematics, especially the one related to the characteristic of cylinder, at elementary school or at the other higher level of school only required the students to memorize the concept of it without comprehending its meaning. Based on that reason, it is a need to have an appropriate learning approach to help the students in understanding the characteristics of cylinder. This research aims to describe the learning activity of cylinder characteristic by using Realistic Mathematics Education (RME). There were five students of grade V from SDN 3 Sigli who were involved in this study.Byusing the approach, the students were motivated to learn about cylinder characteristics more meaningfully. The use of the appropriate context that matches with the students culture also became a strong foundation for them in possessing a meaningful experience toward the material. It also can lead them to have more formal learning experiences (identifying the characteristics of cylinder). There were three kinds of activities that are conducted in the study and were related to introduction the characteristicsof cylinder. They were glueing by using different colour, drawing a tissue place, and unloading the model of the tissue place. The use of concrete objects that relates to the culture of the students to develop their ability in understanding the material of the cylinder was the first step in learning the cylinder volume concept

Abstract

The ability of mathematical creative thinking and self-confidence are ones of the targets in mathematics learning. Therefore, learners need a relevant model to have them be active in searching information themselves, group working, building self-confidence, and improving creative thinking in perceiving and understanding the information to resolve a problem. One of the models is model-eliciting activities to improve students mathematical creative thinking and self-confidence to have students organize their own knowledge in learning. Applying this model, this research was to investigate (1) the differences of students mathematical creative thinking improvement through dividing into low, medium, and high subgroups, (2) the description of students self-confidence in mathematics learning, and (3) the correlation of creative thinking ability and self-confidence in mathematics learning. This experiment used one-group pretest-posttest design. The population was all first year students of SMA Negeri 5 Banda Aceh, and the sample was all students in Class X-IA3. The instruments applied in the research were mathematical creative thinking ability test and self-confidence questionnaire. The statistic testing applied in data analysis was the average difference test, whereas the questionnaire was counted based on the percentage. The result obtained showed that the improvement in students mathematical creative thinking exists in those who applied model-eliciting activities. While, the result from the questionnaire proves that the majority of the students (74.6%) establish positive view toward mathematics learning using model-eliciting activities. In contrast, there was no any correlation between creative thinking ability and self-confidence in mathematics learning.

Abstract

Educational research demands clarity and accuracy in defining variables and understanding the patterns of relationships between them. This article aims to conceptually examine variables in-depth from their definitions and classifications to operational formulations and types of relationships in educational studies. This conceptual review uses literature from the last ten years through a library research approach. The results indicate that a solid understanding of variables significantly affects instrument validity, the choice of analytical methods, and research conclusions. The article also presents concrete examples of each variable type and relationship pattern, such as associative, comparative, and causal connections. Therefore, this study serves as a valuable conceptual reference for researchers, especially beginners, in designing structured, logical, and scientifically grounded educational research.

Abstract

Geometry is one of the mathematics topics that often causes difficulties for junior high school students because it requires visual-spatial abilities and a structured understanding of concepts, leading to misconceptions and procedural errors that impact students' low learning achievement. This research aims to develop a diagnostic test to identify learning difficulties in seventh-grade students regarding geometry material. Researchers used the Research and Development method with the Tessmer model. This stage begins with the preliminary stage, which is conducted thru an analysis of materials and curriculum to design the initial 40 test items. At the self-evaluation stage, the questions are reviewed and refined before being validated. The expert review stage involved two validators, and the initial results showed that 35 questions were suitable and 5 needed revision. In the second stage, all questions were declared suitable. One-on-one testing with several students showed the questions were understandable without further revision, while small group testing with 60 students resulted in 18 questions being acceptable, 17 needing revision, and 5 being eliminated. The final results show 11 easy questions, 28 medium questions, and 1 difficult question, with a reliability coefficient of 0.826, which is considered very high. This diagnostic test is able to identify students' difficulties in understanding concepts, procedures, and misconceptions. Thus, the developed instrument is effective in mapping students' learning weaknesses and supporting more targeted lesson planning.
