Abstract

Students' difficulty in solving numeracy problems is a problem that teachers must pay attention. Therefore, it needs media to help students improve their numeracy ability. The purpose of this study is to develop mathematics problems based on PISA (Programme for International Student Assessment) content and use local wisdom context in Maluku that obtained validity, practically, and effectively. Mathematics problems developed are expected to improve the numeration ability of junior high school students in Maluku. The study was research and development based on the Plomp model. The subject consists of 40 students (15 males and 25 females). The result showed that mathematics problems met validity criteria. The validity was tested using the Rasch model that consists of suitable, reliability, difficulty, and differentiation items. Then, it was validated based on experts in content, league, and media. All of them met validity criteria. Mathematics problems had met practically based on the user experience questionnaire (UEQ) that consisted of interest, clarity, efficiency, accuracy, stimulation, novelty, and prospered based on the system usability scale (SUS). Mathematics problems improve the student's numeration ability, as shown based on N-Gain 0.36. Thus, it effectively improves the numeracy ability of students in Maluku.

Abstract

The development of mathematical critical thinking ability and individual uniqueness in the learning of prospective teacher students needs attention so that they have sufficient provisions in their future work. This study aims to analyze the differences in prospective teacher students' mathematical critical thinking ability in their achievement and improvement from two different learning models and their learning styles. Problem-based learning was used in the experimental group, while the control group used conventional learning. This study used a quasi-experimental quantitative method with the pretest-posttest non-equivalent group design. Data were collected using: mathematical critical thinking ability test and a learning style questionnaire. Data were taken from 56 students of the Mathematics Education Study Program, Universitas Negeri Semarang. Data analysis was performed using independent samples t-test, Mann-Whitney U test, and normalized gain. The results showed that in the achievement and improvement of mathematical critical thinking ability, students who obtained Problem-based learning overall and viewed from a kinesthetic learning style were better than conventional learning. Meanwhile, in terms of auditory and kinesthetic learning styles, the mathematical critical thinking ability of students who obtained descriptive problem-based learning was better. However, in statistical testing, the two groups were not significantly different. Based on these results, Problem-based learning is considered adequate for developing mathematical critical thinking ability, especially for kinesthetic learning styles.

Abstract

This article explains how to analyze test items in arithmetic operation with fractions to obtain the items' level of difficulty and fitness. Data were collected by using multiple-choice questions given to 50 fourth-grade students of an elementary school in Tasikmalaya city. The answers were then analyzed using the Rasch model and Winsteps 3.75 application, a combination of standard deviation (SD) and logit mean values (Mean). The score data of each person and question were used to estimate the pure score in the logit scale, indicating the level of difficulty of the test items. The categories were difficult (logit value +1 SD); very difficult (0.0 logit +1 SD); easy (0.0 logit -1 SD); very easy (logit value –SD). Three criteria were used to determine the level of difficulty and fitness of the questions: the Outfit Z-Standard/ZSTD value; Outfit Mean Square/MNSQ; and Point Measure Correlation. It resulted in a collection of test items suitable for use with several levels of difficulties, namely, difficult, very difficult, easy, and very easy, from the previous items, which had difficult, medium, and easy categories. Rasch model can help categorize questions and students' ability levels.

Abstract

Until now, no research explicitly examines the academic impact on public junior high school students in Singaraja City. The actual condition of the academic impact of online mathematics learning is necessary to be revealed immediately. This information can be used as a basis for teachers designing and implementing mathematics learning to minimize or eliminate the negative impact of online learning. This study involved 507 public junior high school students distributed over four public schools in Singaraja City as the sample. This study used a questionnaire instrument consisting of 14 items, and the data were tabulated based on the responses entered on the google form. The study results showed that students experienced several academic impacts as a result of online learning of mathematics. The academic impacts that students most felt among others: the amount of mathematics material was hard to understand, students doubted the accountability of the grade obtained by their friends, decreased enthusiasm for learning, and students felt that their academic abilities were e not optimal. The conclusion obtained from this study is that online mathematics learning  during COVID-19 had an academic impact on public junior high school students in Singaraja City.

Abstract

Various studies on the development of mathematical literacy tests have not shown any research that focuses on developing mathematical literacy tests using the context of Bugis-Makassar local wisdom with Classical Test Theory (CTT). Thus, this study aimed to produce mathematical literacy tests using the context of Bugis-Makassar local wisdom based on CTT for junior high school students through development research using ADDIE design. The development of the test integrates mathematical literacy and local wisdom elements of Bugis-Makassar. There were 15 multiple-choice items developed and tested on 33 males and 68 females at seventh-grade junior high school students. The trial involved two schools in Makassar City using a convenience sampling technique. The test kit was validated by three mathematicians and produced an Aiken index score in the range of 0.67 to 0.89. The empirical data from the trial results were analyzed using CTT assisted by ITEMAN 4.3 software. The test analysis showed an average category for reliability test scores. As many as 47% of the items were in the medium category, and the rest were in the fair category. Meanwhile, 93% of the items have a good discriminatory ability, and 67% have distractors that were not functioning properly, then the tests items must be revised.

Abstract

Mathematics inequality is an essential concept that students should fully understand since it is required in mathematical modeling and linear programming. However, students tend to perceive the solution of the inequalities problem without considering what the solution of inequality means. This study aims to describe students’ mistakes variations in solving mathematical inequality. It is necessary since solving inequality is a necessity for students to solve everyday problems modeled in mathematics. Thirty-eight female and male students of 12th-grade who have studied inequalities are involved in this study. They are given three inequality problems which are designed to find out students’ mistakes related to the change of inequality sign, determine the solution, and involve absolute value. All student work documents were analyzed for errors and misconceptions that emerged and then categorized based on the type of error, namely errors in applying inequality rules, errors in algebraic operations, or errors in determining the solution set, then described. The result shows that there were some errors and misconceptions that students made caused by still bringing the concept of equality when solving the inequalities problem. It made them did not aware of the inequality sign. Students are still less thorough in operating algebra and do not understand the number line concept in solving inequalities. The other factor was giving “fast strategy” to the students without considering the students’ understanding.

Abstract

Students' ability for HOTS is critical to acquire. However, the PISA survey in 2018 showed that Indonesian participants were at level 1, and the national exam in 2018 indicated that 40% of students had an issue answering HOTS questions. The problem suggests that students solve questions requiring higher-order thinking skills, causing errors. Therefore, the study aimed to analyze student errors based on Newman's Theory in solving HOTS-based math story problems. The method applied for qualitative research with a descriptive approach. Data collection involved 126 grade IX students using HOTS-based math story tests, interviews, and documentation. Students were grouped into three categories from the HOTS-based math story test results: students with good, medium, and low abilities. This step was to find the average and standard deviation of the scores obtained by respondents when completing the given test. Then three students were selected from each category as subjects. The results showed that as many as 50% of students misunderstood the questions, 20% made transformation errors, and 10% errors in reading, processing skills, and encoding. The high error rate of these students shows the poor ability of students to solve HOTS-based math story problems.

Abstract

Indonesian students are indicated to have a low math efficacy. Currently, no psychology scale has been created to measure the math efficacy of Indonesian students, especially for junior high school level students. This study aims to develop a math efficacy scale for junior high school level students or equivalent based on Indonesian students’ characteristics. The study used an exploratory sequential design with mixed methods. The results of qualitative analysis through focused group interviews on two small groups of eight students show that seven major themes were related to mathematics efficacy. Qualitative analysis as the basis for a scale development consisting of 33 items and is administered to 478 participants. The results of the quantitative analysis through validity test with Principal Component Analysis (PCA) shows that four dimensions appeared with total variance explained reaching 60.4%. The model was re-tested for compatibility with Confirmatory Factor Analysis (CFA) and obtained index values of p 0.001 (χ2), 0.047 (SRMR), 0.907 (TLI), 0.918 (CFI), and 0.064 (RMSEA). The four dimensions have met the standard of a fit index with 23 items remaining. The validity test was also supported by Pearson's Product Moment correlation of 0.795 for convergent validity test with Math Attitude Scale (MAS) and divergent validity test of -0.331 with Mathematical Self-Efficacy and Anxiety Questionnaire (MSEAQ). The scale's reliability was very good, with Cronbach's alpha value of 0.918.

Abstract

Slow learners also carry out the implementation of online learning at inclusive elementary schools. Online learning conditions are different from face-to-face learning, and it becomes a challenge for teachers to deliver mathematics learning for slow learner students. Learning mathematics is a learning that is considered difficult by slow learner students. It is because slow learner students have limited cognitive abilities and understanding of symbols, abstracts, and concepts. This study aimed to determine the obstacles in the implementation of mathematics learning, which includes the planning, implementation, and assessment stages for slow learner students at inclusive elementary schools. This research is qualitative research with a descriptive approach, and the subjects were ten inclusive elementary school class teachers in Sleman. The data were collected by interview and analyzed with the help of Atlas.ti software. Based on the analysis results, teachers experienced barriers in implementing online learning. The teacher experienced barriers in planning learning media and limited learning resources specifically for slow learner students at the planning stage. The most significant barriers come from the students' condition at the implementation stage, and another barrier comes from parents and teachers. Furthermore, the barriers in the assessment stage included the limitations of distance and time, the validity of the answers, student independence, and decreased enthusiasm of students for working.
