Abstract

Mathematics is an important subject as it enhances critical thinking, problem-solving skills, and contributes to the advancement of science and technology. However, many students perceive it as a difficult subject, which hinders their interest and performance in learning mathematics. Traditional teacher-centered teaching methods and the lack of engaging learning media contribute to this issue. The purpose of this study is to examine the difference in learning outcomes between students taught using the Problem-Based Learning (PBL) model assisted by interactive media Canva and those taught using the Inquiry-Based Learning (IBL) model assisted by interactive media Canva, focusing on data presentation material in seventh-grade students at MTs. Negeri 1 Bone Bolango. This study employed an experimental research method with a Post-test Only Control Group Design. Two treatment groups were used: the experimental group and the control group. The research participants were 24 students from class VII.2 and 23 students from class VII.3. Data were collected through posttests. The intervention involved using the PBL model integrated with Canva as an interactive learning tool. The results were analyzed using paired sample t-tests to determine significant differences in learning outcomes. The results indicate a significant improvement in students' learning outcomes after the implementation of the PBL model with Canva assistance. The average posttest score increased from 52,17 to a higher value, suggesting better understanding and engagement. In conclusion, the use of the Canva-assisted PBL model effectively improves students' learning outcomes in mathematics, particularly in data presentation topics. This approach can serve as a valuable tool to promote active, student-centered learning in mathematics education.

Abstract

Students frequently respond to problems posed by their instructors through trial and error, without first grasping the underlying concepts. They often perceive the problems as entirely new and unrelated to their previous experiences, leading to a lack of confidence and reinforcing the belief that mathematics is a difficult subject. Consequently, their responses are often incorrect or incomplete. The objective of this study is to describe the mathematical problem-solving abilities of grade XI students on the topic of sequences and series in one of the schools in Bekasi Regency. This research employed a descriptive qualitative method, with data analysis techniques based on the interactive model developed by Miles and Huberman. The subjects of this study were 25 grade XI students selected using purposive sampling. The test instrument consisted of problem-solving tasks, while non-test data were obtained through interviews. The results indicate that students' mathematical problem-solving abilities fall into three categories: 4% of students demonstrated high problem-solving skills, 4% were in the medium category, and 92% were classified as low. A detailed analysis of problem-solving indicators reveals that: (1) in understanding the problem, many students struggled to identify the given information and the goal of the problem; (2) in devising a solution plan, most students failed to select an appropriate strategy, often guessing rather than structuring a logical approach; (3) in executing the plan, students in the low category frequently made calculation errors and misapplied formulas; and (4) in reflecting on the solution, very few students revisited their answers to verify accuracy or consider alternative methods. These findings suggest that students’ mathematical problem-solving abilities remain relatively low, with significant gaps in comprehension, planning, execution, and reflection. Strengthening these aspects through targeted interventions is necessary to enhance students’ overall problem-solving skills.

Abstract

Elementary mathematics education necessitates new instructional strategies that can address the varied baseline competencies and backgrounds of kids. The Eliciting Activities Model is a strategy that prioritizes student-centered discovery to enhance learning outcomes. This study seeks to examine the use of the Eliciting Activities Model on mathematics learning outcomes, focusing specifically on students' beginning mathematical competencies and their educational backgrounds. This quantitative study was carried out in three elementary institutions: SDN Batujajar 3, SDN Sukamaju, and SDS Yayasan Beribu, encompassing a total of 81 pupils. The research utilized a survey methodology and applied Two-Way ANOVA to investigate the impact of school origin and beginning mathematical proficiency, along with their interaction, on mathematics learning outcomes. The data gathering process included pre-tests to evaluate students' basic mathematical competencies and post-tests to measure learning results following the implementation of the model. The findings indicated substantial disparities in mathematics learning outcomes contingent upon school origin and pupils' beginning competencies. A notable interaction effect was observed, wherein students with high beginning ability from SDS Yayasan Beribu attained superior learning outcomes relative to students from SDN Batujajar 3 and SDN Sukamaju. The findings indicate that the Eliciting Activities Model effectively improves mathematics learning outcomes, especially when tailored to students' beginning skills and the educational environment.

Abstract

This research is motivated by the significance of mathematical reasoning in problem solving, while self efficacy is considered to influence its development. The objective of this study is to the level of mathematical reasoning ability and self efficacy while also investigating the relationship between these two variables in SPLDV material. The study employs a quantitative approach with a correlational design. The research participants numbered 32 people from class VIII at a junior high school in Karawang Regency. Data collection was done using a mathematical reasoning ability test and a self efficacy questionnaire, both of which were analyzed through descriptive and inferential statistics. The descriptive analysis provides an overview of students mathematical reasoning ability and self efficacy levels, while the inferential analysis applies the Pearson Product Moment correlation test to determine the relationship between the two variables. The descriptive analysis revealed that the average score for students mathematical reasoning ability was 40.63, lacing it in the moderate category, indicating that not all indicators of mathematical reasoning were well achieved. The average self efficacy score was 86.34, which also falls within the moderate range. The inferential analysis showed a strong and significant relationship between mathematical reasoning ability and self efficacy, with a correlation coefficient value of 0,803 and Sig.(2-tailed) = 0,000 where 0,000 < 0.05. This reveals the greater the students self efficacy, the better their ability in mathematical reasoning.

Abstract

Problem-solving ability is an essential skill that must be possessed by students, especially in Vocational High Schools (SMK), in order to apply the concepts learned in real situations. However, many students have difficulty in identifying and solving mathematical problems because the learning method is still centered on the teacher and the minimal use of interactive learning media. This study aims to analyze the mathematical problem-solving ability of vocational high school students whose mathematics learning uses the Problem Based Learning model assisted by interactive media canva and quizizz compared to those who use regular learning. This study uses a quasi-experimental method with a Nonequivalent Control Group Design. The research sample consisted of 64 grade XI students of SMKN 1 Cariu, which were divided into an experimental class (32 students) who received learning using PBL assisted by interactive media Canva and Quizizz, and a control class (32 students) who used regular learning methods. Data collection was carried out through problem-solving ability tests (pretest and posttest), questionnaires and observations. Data analysis using inferential statistics, namely the average difference test with N-Gain as a measure of learning outcomes, and thematic analysis for qualitative data. The results of the study showed that the mathematical problem-solving ability of vocational high school students whose mathematics learning used the Problem Based Learning model assisted by interactive media canva and quizizz was better than those who used regular learning.

Abstract

The purpose of this study is to analyze the mistakes made by students while working on math problems in Sequence and series. The background to this study is that it is difficult to understand students during their studies, which leads to mistakes in solving the math problems of Sequence and series. The purpose of this study is to determine what mistakes are common in solving questions about Sequence and series. The subjects of this study were 10 students of eleventh grade at SMK Plus Darussurur, Cimahi City. The data collection method uses written essay questions with results obtained from the analysis of the level of error based on the Kastolan Theory.  Based on the results of the research and discussion, it was found that the level of student errors in working on sequence and series problems is as follows : 1) Conceptual errors with a percentage rate of 50% with the criterion of "High Enough" error rate; 2) Procedural Errors with a percentage rate of 32.1% with the criterion of "Low" error rate; 3) Technical errors with a percentage of 17.9% with the "Very Low" error rate criterion. From this, we can conclude that the common error in solving the Sequence and seriesproblem is a form of conceptual error. This means that the students' conceptual understanding of Sequence and series is still lacking. Because learning tends to focus on procedures without linking basic concepts, lack of visualization and real context, and limited abstract thinking skills and varied exercises.
