Abstract

Previous studies reported the student’s difficulties in algebraic reasoning for solving problems involving quadratic equations. Mostly full to the agreement of understanding and solving quadratic equations is the conceptual challenge in subject mathematics. Integrating technology in the national school curriculum enhances the teaching and learning development throughout the science, engineering and mathematics in the facets of multidiscipline skills and reasoning in context. A quasi-experiment was conducted to determine the effects of Geometer’s Sketchpad (GSP)-based instruction through using Geometer’s Sketchpad on the algebraic reasoning abilities of Junior Two students. The experimental study was conducted on 60 Junior Two students, who were equally divided into experimental (30 students) and control groups (30 students). The data were collected through algebraic reasoning abilities test. Data were analysed using ANATES 4 and SPSS 25.0. Inferential statistics including the independent sample t-test was used in analyzing the quantitative data obtained. Significant differences were found in the algebraic reasoning abilities of students in relation to quadratic problem solving according to their group type. GSP-based instruction helped students develop their algebraic reasoning abilities in the instructional intervention and provided insights for mathematics educators into utilising the software. Moreover, the effect of the GSP-based instruction enhanced the algebraic reasoning abilities of students without influence of prior knowledge.

Abstract

This study describes the effectiveness of the Self-Regulated Learning (SRL) model to improve students' academic abilities in mathematics classes. Many studies suggest that the ability of Indonesian students to solve problems is still relatively low. Students are not allowed or encouraged to optimize their potential, develop reasoning and creativity, thereby causing the knowledge provided to be less meaningful. The success of this study was determined through three effectiveness criteria. This research design used by giving assignments to students. Assignments were completed using strategies chosen by students. The task is reflected and then evaluated. This process is carried out in the mathematics class. The class chosen is a 7th grade mathematics class with statistics and Opportunities. The three criteria are (1) the average mastery of teaching materials students meet the KKM, (2) student activities according to the syntax of the SRL Model, (3) students' responses to the learning of the SRL Model are Positive. The results of the application of the SRL model that has been done. First, students are able to complete the category very well. This is evidenced by the achievement of the average score of Mastery of Teaching Materials above the KKM score. Second, student activities are in the active category. This is indicated by the average score of the observers during the four meetings included in the active category in learning. Third, students' responses to learning have been positive.

Abstract

Based on previous research, one of the gender differences between men and women in mathematics is problem solving skills. Gender differences in mathematical problem solving can be an indication of the different errors experienced by male and female students. The question of this research is what kinds of error are made by students in solving indefinite integrals viewed from gender differences? While the purpose of this research is to describe the type of errors made by students in solving indefinite integrals viewed from gender differences. This research is a qualitative research using a descriptive research methodology approach. The subjects were 3 male students male and 3 female students taken by purposive sampling. Data were collected from indefinite integral test, which are used to determine the type of the students’ fault in solving problem based on indicators Newman. Indefinite integrals in this research regarding indefinite integral by substitution and integration of fractional function by partial fraction. From the result of the study, it was found that for integral substitution problem, all of the male students could solve the problems well, while female students made transformation and process skill errors. In a matter of integration of rational function by partial fractions, 1 male students encountered process skills error, while two other male students encountered comprehension error. For female students, the error that occurs is transformation error.

Abstract

Many students have difficulty solving the word geometry problem because it requires representation. This study analyzes the construction of representation of class XII students in solving three dimensional word problem. Research with descriptive methods to determine the representation construction that students use when given the task of solving three dimensional word problem. The results showed two constructs of representation, namely: pictorial representation and schematic representation. Students who construct pictorial representations produce correct answers while students who construct schematic representations produce correct answers in solving three-dimensional word problems.

Abstract

The development of science and technology needs to be accompanied by an increase in the quality of human resources, including through education. Education is closely related to the learning process so that one way to improve the quality of human resources is by choosing a learning model that involves technology during the learning process. One learning model that uses technology during the learning process is the Moodle-based Hybrid Learning model. The use of the Moodle-based Hybrid Learning model can help students understand the subject matter. Cognitive aspects are one important component that must be owned by students but these aspects are still relatively low. Therefore, the purpose of this article is to: 1) describe student activities during the implementation of the Moodle-based Hybrid Learning model in mathematics learning; and 2) determine the effect of Moodle-based Hybrid Learning models on student mathematics learning outcomes. This type of research is a quantitative research with experimental methods in the form of pure experimental types carried out at SMAN Negeri 1 Tembilahan Hulu with a sample size of 33 experimental classes and 33 control classes. The data collection method used in this study is a test technique. Based on the results of the analysis it can be concluded: 1) the implementation of the Moodle-based Hybrid Learning model is classified as good as seen from the mean values ​​of the experimental class 19.97 while the mean control class is 17.52; and 2) there is an influence of Moodle-based Hybrid Learning models on student mathematics learning outcomes.

Abstract

This research was inspired by the lack of ICT-based learning media in linear program material. Linear program material has the potential to be developed visually using computer devices to facilitate students in understanding the linear programs. The aim of the study was to develop ICT-based mathematics learning media that met the validity, practicality and effectiveness. The instruments used in this research were material validation sheets, media validation sheets, response questionnaires and student achievement test. Questionnaire sheets were analyzed quantitatively and qualitatively. Based on the results of data analysis and discussion, it can be concluded that the ICT-based media of mathematics learning is valid with an average score of 3.36 by the material validator and 3.42 by the media validator. This learning media also fulfills practical requirements with an average student response of 3.45 in small group trials and 3.18 in large group trials. Learning media also influence students achievement learning. Student achievements in this research are in sufficient criteria that is 65.21%.
