Abstract

Mathematicals communication ability is one of essential mathematical abilities that every person, who learns mathematics, needs to have. However, many facts found in many studies has shown us that students’ achievements on this ability are still low. Factors that may cause it spread from teacher factors, tools, approaches, learning media to students themselves. To overcome these issues, many efforts are made to select and implement learning approaches that can improve students' mathematical communication ability as well as their activities in instructional process. Thus, the purpose of this study is to examine whether the implementation of GeoGebra-assisted discovery learning approach is effective in improving vocational school students' mathematicals communication ability or not. This quasi experimental research design involved 60 students of Gema Karya Bahana Vocational School as samples. The samples were divided into two groups in which 30 students of Accounting-1 class as the experimental group and 30 students of Accounting-2 as the control group. The data collected through a description test consisted of 3 questions on a linear program. The data collected through the test, both in pre-test and post-test, then analyzed using inferential statistics. The results of this analysis showed that the implementation of the discovery Learning approach assisted by GeoGebra was effective in improving vocational school students' mathematicals communication ability. Thus,  the discovery learning approach assisted by GeoGebra can be implemented on instructional processes as one of  instructional approach alternatives.

Abstract

Communication is one of the important skills that students must have in mathematics. Engaging in communication activities helps provide an understanding of mathematical communication skills to students. However, in reality, students' mathematical communication skills are still in the low category. Therefore, a more interactive learning method is needed. This study was conducted to analyze the effectiveness of the Realistic Mathematics Education (RME) approach in improving mathematical communication skills.The method used in this research is a literature review with inclusion and exclusion criteria focusing on studies containing quantitative or qualitative data. The data collection technique involved gathering relevant National and International Journal articles published between 2019 and 2023. From the numerous articles found, researchers selected 21 articles related to this study. The data processing technique applied in this study examined the effectiveness of using Realistic Mathematics Education (RME)  to improve communication skills in the collected articles. The results showed that RME is an effective learning approach for improving students' mathematical communication skills. In addition to Realistic Mathematics Education (RME), classroom learning can be enhanced with various media, such as Audio Visual Media or Learner Worksheets (LKPD). This approach makes classroom learning more interactive and receives positive responses from students, helping them understand the material better by expressing mathematical ideas through oral and written language and making arguments with confidence.

Abstract

It is important for students to have problem solving abilities, but in the field problem solving abilities are very low. Therefore, the aim of this research is to see an increase in students' mathematical problem solving abilities by implementing the Discovery learning model. This research was conducted at one of the Islamic junior high schools in Bandung Barat regency. This research is experimental research methods. The research sample was class VII B, totaling 18 people. The data collection technique uses tests, namely pretest and posttest with 5 test questions in the form of descriptions to determine students' mathematical problem solving abilities.The data analysis techniques used are prerequisite analysis and hypothesis testing. The results of the research are that the problem solving abilities of students whose learning uses the Discovery Learning model after being given learning are better than before being given the learning. This is shown through the results of the t test using the dependent t test which obtained a significant value (2-tailed) = 0.000. The n-gain test result was 0.5767 or 57.67%, which means that the effectiveness of implementing the Discovery Learning model in mathematics learning is in the medium category or can be interpreted as quite effective. So it can be concluded that the application of the learning model with the Discovery Learning approach can improve student problem solving and help students become more proficient in solving mathematical problem.

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

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.
