Abstract

Although many scholars support the Lakatosian method of mathematics education for enhancing students learning, the use of the method to foster students’ transition from alternative to scientific conceptions in mathematics does not seem to have been a focus of any research. This study explored if the Lakatosian heuristic method of teaching could foster a students’ transition from alternative to scientific conceptions of the surface area of a cone. The study used a qualitative, exploratory single case study design to undertake an in-depth study of a student in the 11th grade at a secondary school in Cyprus. Data was collected through lesson observation and analyzed using deductive content analysis.  The study found that beginning from informal conjectures and proofs to more formal proofs the student was able to transit from alternative conception to the scientific conception of the surface area of a cone. The finding suggests that the Lakatosian method of mathematics can foster students’ conceptual understanding of some mathematical concepts.

Abstract

In this study, attitudes of pre-service teachers (PSTs) towards statistics and towards probability were examined. A sample of 184 level 300 students of the Evangelical Presbyterian (E. P.) College of Education, Bimbilla who undertook the Statistics and Probability II course for the second semester of the 2020/2021 academic year was used to conduct the study. The main objective of the study was to determine PSTs attitude towards statistics, attitude towards probability, and the differences in attitude that exist among them. The study also investigated the relationship between attitudes towards statistics and attitudes towards probability. The sample was selected through purposive and simple random techniques from level 300 students who either pursue mathematics as a major or as a minor subject. Two sets of questionnaires, one for attitudes towards statistics and the other for attitudes towards probability were administered to the selected respondents. The data was analyzed using SPSS version 24 by employing both descriptive and inferential statistics such as frequency counts, percentage, mean, standard deviation, paired sample t-test, and correlation. The results revealed that pre-service teachers have a positive attitude towards statistics than probability. Also, 93.5% and 83.2% of the Pre-service Teachers respectively consider statistics and probability very useful and necessary courses that will prepare them for the job market. Again, the Pearson correlation coefficient revealed a moderate positive association between Pre-service Teachers' attitudes towards statistics and towards probability.

Abstract

The recent globalisation and the emergency of COVID-19 require a teaching and learning environment that encourages the use of technology. Through a mixed-method design and an action research approach, this study investigated the effectiveness of a flipped classroom model through multimedia technology in improving students’ performance in directed numbers, given the difficulty and misconceptions of students in this mathematical concept. A total of 30 Year 9 students conveniently sampled from one of the secondary schools in Brunei Darussalam served as participants. The action taken involved a pretest, intervention, posttest, and interviews. The results of the paired sample t-test revealed that students’ performance in directed numbers significantly improved after the flipped classroom intervention. Students had positive perceptions of the flipped classroom model as it encouraged their readiness, participation, and motivation. Challenges such as time constraints and distractions when studying from home were reported. These results imply that amid COVID-19, a flipped classroom through multimedia technology can be an effective and alternative way of teaching and learning directed numbers. It has the potential of encouraging student-centred learning and creativity, which are vital in teaching and learning mathematics.

Abstract

Mathematical creative thinking ability is essential to be mastered by students to create good learning results and achievement. To install creative thinking in students' minds, they are highly requested to apply an innovative learning model. Among innovative learning models, project-activity-cooperative learning-exercise (PACE) is the one to be considered suitable for improving the students' mathematical creative thinking. This study is an experimental research using a pretest-posttest control group design. It was conducted in three classes of IKIP Siliwangi students by applying different learning models. The first class was given the PACE model treatment with Geogebra, the second class was given the PACE model treatment, and the third class was given direct learning. The instrument used tests. Based on the data analysis, we can conclude that there are differences in improving creative thinking abilities among the students who get the PACE model learning with Geogebra (PACE-G), the PACE model, and direct learning (DL). The improvement of creative students who get PACE and PACE-G models is better than those who get DL. The progress of students' mathematical creative thinking abilities obtained from PACE and PACE-G models is a high category. In contrast, improving students' creative thinking abilities who acquire DL is categorized as a medium.

Abstract

The teaching-learning process is analyzed in a course for a group of professors who were taught subjects on Calculus, to study the episodes of problem-solving in them, focused on the identification of patterns and argumentation using counterexamples. The explanation and the argument in the classroom can be used together so that the argument (issued as a counterexample) supports the explanation (conjecture). Developing the mathematics class so that the above occurs is a form of interaction and how to encourage students to move from explanation to argumentation (placing a hybrid system). Furthermore, both forms of reasoning can influence dialogue protocols and strategies. In this work, the dialogue model is described as a tool to address the problem that arises when working with students.

Abstract

This study aims to determine students' mathematical critical thinking skills after the implementation of learning using PMRI and LSLC on social Arithmetic material with the help of animated videos in class VII. This type of research is descriptive. The subjects of this study were students of SMP Negeri 1 Palembang class VII.1, totaling 32 students. The data collection technique used is the provision of test questions which amount to 2 questions in the form of descriptions, observations, and interviews. After doing the research, it was found that the mathematical critical thinking skills of class VII.1 students on social Arithmetic material, the subject of sales, purchases, profits, losses, and percentages had appeared a lot. However, some students still did not show indicators of their mathematical critical thinking abilities. The indicators that seem the most are the analytical indicators, while the indicators that appear the least are the interpretation indicators.

Abstract

Solving word problems with a thought jump shows flexibility and the ability to use alternative procedures that are important for students to master. The thought jump is a feature of the lateral thinking process and is needed to overcome the various difficulties in solving mathematical word problems. However, lateral thinking has not been widely linked with adversity quotient and reflective cognitive style. This study aimed to describe students' lateral thinking processes in solving word problems in terms of adversity quotient and reflective cognitive style. This research is a qualitative descriptive study. The subjects in this study were junior high school students in Gowa Regency, South Sulawesi Province. The research instrument used the MFFT diagnostic test, ARP questionnaire sheet, word problem text, and interview guidelines. The results of this study indicate that climber-reflective subjects can think laterally and use them to solve the first and second-word problems well. Camper-reflective subjects can only think laterally for situations that are still within reach, while for more complicated cases, camper subjects are easily distracted and even stop solving problems. Quitter subjects solve word problems very procedurally, follow rigid algorithms, and cannot work backward when faced with difficulties.

Abstract

The purpose of this study was to investigate the critical role of equilibration in organizing and building students' cognitive structure in the practice of learning mathematics. This qualitative research was designed using a phenomenological study approach. Participants in this study were 30 high school students of XI level. The main research instrument was the interview guide format and the document of cognitive test questions with the circle equation material. Research data obtained were tested for the validity of the data by triangulation. Method triangulation was done by comparing student work data and interview data. Theory triangulation is done by comparing the descriptions of the data obtained with the relevant theoretical sources. The results showed that in the context of knowledge construction (cognitive structure), there is a strong relationship between the process of assimilation and accommodation with equilibration. The role of balance in forming cognitive structures is to guide students to organize previous knowledge (schemas) and new knowledge and create thinking structures to become more complex by considering the socio-cultural dimension (environment) in mathematics learning. Further studies suggest that when selecting topics for equilibration-based activities, teachers should provide an effective learning environment to support the formation of cognitive structures to become more prosperous and complex.
