Abstract

Abstract. During this learning is given by the teacher to his students. Teachers only provide material by using learning strategies based on certain learning theory without wanting to know that learning has been appropriate or not. Then the question arises again, whether the desired student learning is desired by the teacher? Because the teacher may be more aware of the condition of all students and learning environment. This becomes a paradox about the truth of a suit that some people think is appropriate but not for others. This study aims to determine which learning theory is considered appropriate according to the perspective of teachers and students. It is expected that mutual understanding of teachers with students will improve student achievement. This study will explore and compare the perceptions of students and teachers in Indonesia with the theory of learning behaviorism and constructivism. Using qualitative survey research methods, students and teachers describe the advantages and reasons why learning with learning theory is appropriate. The results of this study showed that most students and teachers perspective like learning with constructivism theory, but factors such as time allocation and student confidence are so influential that learning theory of behaviorism is used more often.

Abstract

Pusat Kegiatan Belajar Masyarakat (PKBM) that facilitate A, B and C packet become alternative solutions in reducing dropout rates. However, teaching and learning activities at PKBM is not yet feasible. In this article, we report the case study results by giving algebraic test for students packet B. The aim is to observe at students algebraic abilities and matching the difficulty found with the type of difficulty based on AVAE theory. First, we given algebraic test for the students from ujian nasional kesetaraan paket B last year. Next, we analyzed student results and matched student answers based on the types of algebraic difficulties in AVAE theory. We found that students algebraic abilities are still low and students difficulties in answering algebraic test correspond to the types of algebraic difficulties in AVAE theory. These findings suggest that students algebraic abilities need to be a major concern for improvement and the difficulties that exist in students are not much different from the findings gained in the results of research that created the AVAE theory. For further investigation, we consider to examine the problem designed based on the difficulties put forward in AVAE theory on students of Packet B and analyze the results.

Abstract

This paper aims to analyze the aspect of mathematical metacognition skills of students in Junior High School based on cognitive style. Metacognition is an important factor of mathematical problem solving. Metacognition is the ability to monitor and control our own thoughts, how we approach the problem, how we choose the strategies to find a solution, or ask ourselves about the problem, in the other word, it can be defined as think about thinking. Another thing that needs attention in mathematical problem solving is cognitive style. Cognitive style refers to a persons characteristics in responding, processing, storing, thinking, and using information to respond to a task or different types of environmental situations. Cognitive style that used in this paper are Field Dependent (FD) and Field Independent (FI) cognitive style. People with FD cognitive style tend to perceive a pattern as a whole, it is difficult for him to focus on one aspect of the situation or analyze a pattern into various parts and people with FI cognitive style tend to perceive separate parts of a pattern according to its components.

Abstract

This article was written based on the results of student learning evaluation after learning combination by using Local Instruction Theory (LIT) teaching materials in realistic mathematics education. This study aims to explain the process of mathematical modeling of students in solving the problem of combinations that refers to the process of horizontal and vertical mathematization. The research method using case study approach by classifying the students into three categories of ability that is high, medium and low. From each capability category, one student is selected as the subject of the study. The results showed that students in high ability category, can perform all modeling process including the process of horizontal and vertical mathematization well. Students in the medium category, can perform the second stage modeling process that students can understand, simplify, perform the process of horizontal mathematization but students have not achieved vertical mathematization. Students in the low ability category are only able to work in the earliest modeling stages of understanding, simplifying and incomplete horizontal mathematization.

Universitas Pendidikan Indonesia


Abstract

Knowing the two contexts of trigonometry both trigonometry as ratios of right-angle triangle and trigonometry as a function is important to students. Educational research has shown that students could not distingush between these contexts and understand why trigonometry is a function. Study showed that a unit circle context can be a glue between them. However, the transition from the triangle concept to unit circle concept is not well delivered. In this study we propose a lesson design for trigonometric to filling the gap between right triangle context and circular function context. This study is underpinned by the previous research proposed by Altman & Kidron (2017) that describe how is students cognitive process through constructing knowlegde. We also report on the results of a classroom case study in which the design has been implemented and researched through a phenomenological investigation based on interviews, classroom observations. We discuss the task-related difficulties that students faced in their concept development. The results of the study suggest that the design can link between trigonometry as ratios of right-angle triangle context and unit circle context. Also, we suggest that prior knowledge of students is the main indicator in order to the design runs well. A consideration of technical support in group work devision is also discussed.

Abstract

The problem of this research is how to identify the level of students mathematical anxiety in junior high school. The purpose of this research is to find out descriptively the level of anxiety owned by junior high school students and the difference between students anxiety based on gender and class. The method used is descriptive quantitative study using anxiety questionnaire. The population of the study were all students of Class VIII consisting of 7 classes. The number of samples was 95 students taken with cluster random sampling technique. The research data is a statement that measures students anxiety. Data were analysed using descriptive statistical, t-test and Kruskal Wallis. The results showed that the condition of mathematical anxiety level is in a low category. There is a difference in mathematical anxiety level of students seen from the class category. There is no difference in the mean mathematical anxiety of students seen from gender. The novelty and impact of the results of this study are, it turns out the results of previous research which states that women tend to be more anxious than men is not proven. A low level of student anxiety is expected to improve the quality of student learning.
