Metacognition Process of Students with High Mathematics Anxiety in Mathematics Problem-Solving
Get PDFThis study aims to find out students’ metacognition process while solving the mathematics problem. It focuses on analyzing the metacognition process of students with high mathematics anxiety based on Polya’s problem solving phases. This study uses qualitative research with case study strategy. The subjects consist of 8 students of 7th grade selected through purposive sampling. Data in the form of Mathematics Anxiety Scale (MAS) result and recorded interview while solving mathematics problems were analyzed qualitatively using Miles and Huberman steps. Before selecting the subjects, the researcher gave the Mathematics Anxiety Scale (MAS) to obtain students with high anxiety. Then, subjects were interviewed while solving the problem to investigate their metacognition process. The results show that: (1) The metacognition processes of students with high anxiety in understanding the problem involve planning, monitoring, and evaluating to explore and understand information of the given problem. (2) The metacognition processes of students with high anxiety in devising a plan involve planning and monitoring to identify the possible strategy for solving the problem. (3) The metacognition processes of students with high anxiety in carrying out the plan involve planning to use the strategy and procedures to find the solution. (4) In the final steps namely looking back, there is no metacognition process of students with high anxiety identified. Thus, it can be said that the high of mathematics anxiety can cause the lack of students’ metacognition process while solving the mathematics problem. Therefore, it is important for the teachers to consider students mathematics anxiety to design and plan better mathematics learning.[1] NCTM 2000 Principles and Standards for School Mathematics NCTM 2000 (Virginia: NCTM) [2] Jonsson B, Norqvist M, Liljekvist Y and Lithener J 2014 Learning Mathematics through Algorithmic and Creative Reasoning the J of Mathl Behaviour 36 20-32[3] Mullis I.

Analysis of contextual teaching and learning (CTL) in the course of applied physics at the mining engineering department
Get PDFApplied Physics is used to comprehend any other technical engineering studies and as the foundation of technology innovation. As one of the curriculum components in helping the students to be competent in certain skills, it is used to develop intellectual, attitude, interest, skill and creativity. Physics is a course containing materials in form of fact, concept, principle and procedure. The method used in this research was literature studies and observation. The purpose of the research was to analyze whether the seven CTL principles are needed in Applied Physics or it can be simplified. The seven principle used in Indonesia are constructivism, inquiry, questioning, learning community, modelling, reflection and authentic assessment. Having conducting literature studies, especially for Applied Physics, inquiry can be applied along with questioning. Modelling is not the priority because Applied Physics does not need the real model, but only needs an example for Mining Engineering. Meanwhile, reflection has been accommodated in every learning step. Conclusively, constructivism, inquiry and questioning, learning community and authentic assessment are the steps needed during the learning of Applied Physics using CTL approach

Teaching Style and Mental Representation of Teachers in Biology Learning Using Convention Picture
Get PDFActivities of teacher’s working memory in representing a picture are important in the teaching and learning process. This study aimed to reveal the tendency of teacher’s mental representation and teacher’s teaching styles in biology class using convention pictures. This research used descriptive method. The research was conducted by involving four high school biology volunteer teachers of grade XI from four schools in Lebak, Banten, Indonesia. Teacher’s teaching styles were measured by questionnaires and rubrics adapted from Grasha and teacher’s mental representations were measured using worksheets and rubrics developed based on the Causal Network Elicitation Technique (CNET) model. The data obtained were analyzed qualitatively. The results showed two dominant teacher teaching styles; there were expert style and facilitator style. The mental representation of teachers when reading convention picture was in the category of good (2 teachers), adequate (1 teacher) and inadequate (1 teacher). A teacher with expert teaching style tends to have a good mental representation compared to a teacher with facilitator teaching style
