Abstract

Penelitian ini bertujuan untuk mendeskripikan: (1) pengaruh adversity quotient dan task commitment secara bersama-sama terhadap kemampuan pemecahan masalah matematika; (2) pengaruh adversity quotient terhadap kemampuan pemecahan masalah matematika; dan (3) pengaruh task commitment terhadap kemampuan pemecahan masalah matematika. Metode penelitian adalah survei korelasional dengan teknik analisis regresi ganda. Sampel penelitian terdiri dari 83 siswa SMK di Jakarta Selatan yang diambil dengan teknik simple random sampling. Instrumen untuk mengukur adversity quotient dan task commitment menggunakan angket tertutup, sementara kemampuan pemecahan masalah matematika diukur dengan tes uraian. Hasil penelitian menunjukkan bahwa: (1) terdapat pengaruh positif signifikan adversity quotient dan task commitment secara bersama-sama terhadap kemampuan pemecahan masalah matematika  dengan kontribusi sebesar 12,3%; (2) terdapat pengaruh positif signifikan adversity quotient terhadap kemampuan pemecahan masalah matematika dengan kontribusi sebesar 5%; dan (3) terdapat pengaruh positif signifikan task commitment terhadap kemampuan pemecahan masalah matematika dengan kontribusi sebesar 7,3%.AbstractThis research aims to reveal: (1) the effect of adversity quotient and task commitment on mathematical problem solving abilities, (2) the effect of adversity quotient on mathematical problem solving abilities, and (3) the effect of task commitment on mathematical problem solving abilities. This research was a correlational survey with multiple regression analysis technique. The sample was 83 students of three state vocational high schools in South Jakarta, Indonesia, established using the random sampling technique. The instrument to measure independent variables (adversity quotient and task commitment) is a closed questionnaire and that to measure the dependent variable (the mathematical problem solving abilities) is a mathematics description test. The results show that: (1) there is a positive effect of adversity quotient and task commitment together on mathematical problem solving ability, with a contribution of 12.3%; (2) there is a positive effect of adversity quotient on mathematical problem solving abilities, with a contribution of 5%; (3) there is a positive effect of task commitment on the mathematical problem solving abilities, with a contribution of 7.3%.

Abstract

This study aims to describe the difference in creativity and mathematics achievement between gifted students who were taught by Treffinger's learning and those who thought by the expository learning in trigonometry material. This study is a quasi-experiment using a pretest-posttest group design with a population of all gifted students in class X of a State Senior High School in Bali, Indonesia. The sample was established randomly. Observation sheets, pre-test, post-test, and student creativity questionnaires were used, all of which have been validated. The data were analyzed descriptively and inferentially with the paired sample t-test to test the mean difference of the pre-test and post-test data. The results show that the average creativity of students in the experimental class is significantly higher by 9.46 points than that of the control class. In terms of mathematics learning achievement, the average gain score in the experimental class increased significantly by 58.365 points. It can be concluded that Treffinger’s learning is effective in increasing creativity and mathematics achievement of gifted students in trigonometry material.

Abstract

This study aims to describe the reasoning abilities of high school students in Pandeglang Regency, Indonesia in solving post-Covid-19 PISA model math problems. The subjects of this study were 80 students of two state senior high schools in Pandeglang Regency, Indonesia. The data collection used a written test consisting of four description questions in the form of PISA model math questions (levels 2, 3, 4, and 5), and were through interviews and documentation. The data analysis followed the steps of data reduction, data presentation, and conclusion drawing. The results show that the reasoning abilities of Pandeglang Regency high school students in post-Covid-19 are fair in following the rules of inference, checking the validity of arguments, proving, drawing logical conclusions, using patterns, analyzing mathematical situations, and generalizing. However, the reasoning abilities were very poor in providing explanations of models, facts, characteristics, and relationships; constructing valid arguments; and studying conjectures. Thus, it can be concluded that the mathematical reasoning ability of Pandeglang Regency senior high school students is poor when measured using the PISA Post-Covid-19 model of mathematics questions.

Abstract

This quantitative-qualitative descriptive study aims to reveal the mathematics understanding of prospective student-teachers, describe the types of their mistakes in mathematics understanding, and recommend appropriate teaching of mathematics understanding. The subjects were 34 first-year students taking the Geometry course in the Mathematics Education Study Program, at a State University in Yogyakarta, Indonesia. The test instrument was consisting of four items, two of which were about the problems of procedural instrumental understanding and the other two were about the problems of relational understanding. The data were analyzed through the stages of reducing data, presenting data, and concluding data. The results show that students' mathematical understanding is categorized as good (87.75%). Students' procedural instrumental understanding (87.75%) is better than their relational understanding (77.52%) which is in good and sufficient categories, respectively. Some students made mistakes in representing theorems, performing mathematical procedural using appropriate concepts/theorems, and interpreting conclusions or proofs using appropriate notation and representation. It is recommended that mathematical learning should prioritize relational understanding by exploring a concept with other concepts and using various representations, situations, and contexts. Learning should focus more on relational understanding, namely discussing a concept and its relationship with other concepts with different representations, situations, and contexts.

Abstract

This study aims to reveal the metacognitive failures experienced by mathematics pre-service teachers based on their mistakes when solving problems in online learning during the pandemic era. This case study involved 29 participants who attended the mathematical problem test and cognitive style test, the two participants were categorized based on their cognitive style: Field Dependence (FD) and Field Independence (FI). The instrument used was a mathematical problem test to collect data on metacognitive that adapted from Stewart and a cognitive styles test to categorize the cognitive style that adapted from the Group Embedded Figures Test (GEFT). An interview was conducted to determine the nature of mathematical error based on metacognitive failure. The description of data analysis and interpretation of the meaning of the findings applied the text analysis. The results showed the different metacognitive failures of the two participants. The metacognitive failure of FI student was categorized as metacognitive blindness and the FD student was categorized as metacognitive stagnation, a new condition of metacognitive failure that was found in this study.

Abstract

The study aims to identify the effect of learning motivation and self-regulated learning on learning achievement in “Derivative” learning materials in Trigonometry Functions. The study was field research using the ex-post facto design and quantitative approach during the Covid-19 Pandemic. The population was all grade XII students of a state Islamic senior high school in South Kalimantan, Indonesia. The samples of 24 students were selected using the purposive sampling technique. The data were gathered using a questionnaire and test and through documentation and interview. The data were analysed using the descriptive statistics and the inferential statistics consisting of normality test, linearity test, multicollinearity test, heteroscedasticity test, and multiple linear regression. The result shows that there is an effect of motivation and learning independence during the Covid-19 pandemic, which contributed 90.9% in increasing mathematics learning outcomes, and the rest was affected by other variables. This result is based on the results of F-test (Fcount = 104.948 Ftable =3.47) at the significance level of 5% with a multiple linear regression model Ῠ= 13.557+0.435 X1+0.395 X2 + ɛ.
