Abstract

One of the competencies which students must possess is a mathematical understanding. Another aspect that supports understanding is self-concept. An effort that can be taken as a solution for improving students? understanding and the self-concept is a model of learning which can lead students to find their concept. This model is often called discovery learning. This study aims to improve students? mathematical understanding and the self-concept through the discovery learning model. In this study, the researcher used quantitative research. The population of this study was all senior high school Ulumuddin students in the 2016/2017 school year. The sample of this study was 40 students in grade 10 who were randomly chosen from two classes. The data in this study were obtained using instruments compiled in the form of questionnaires and tests that were answered by the respondents. The results showed that the improvement of students? mathematical understanding and self-concept who obtained learning with the discovery learning model was better than students who gain learning without using the model of Discovery Learning. However, there was no interaction between the model and the levels of understanding and the self-concept of students.Keywords: mathematical understanding, self-concept, discovery learning.

Abstract

Interest geometry are taught is to develop spatial ability so as to impart knowledge to support other materials. As NCTM specify one of five content standards in mathematics, namely geometry measurement an important element involves the use of visualization and modeling. This shows that modeling is the demands of the curriculum that must be accommodated in the classroom. Therefore, teachers should be able to apply the learning object model that abstracts from geometry into real situations imaginable learners. One lesson that applies the use of models that help learners build their own knowledge is Realistic Mathematics Education (RME). Shaped media selection Information and Computer Technology (ICT) can also meet the demands of the curriculum on the use of visualization to teach geometry. One of ICTs to facilitate learners to imagine something abstract geometry of the object is Cabri 3D software. But in reality there is no learning device that integrates Cabri 3D geometry once using RME approach. This study aims to develop and produce devices RME-assisted learning Cabri 3D is valid, practical, and effective. This research is a research development refers to the model of Dick and Carey consisting of nine steps, namely the identification of learning objectives, learning analysis, identification of the characteristics of learners, formulate learning objectives, develop test items, develop learning strategies, develop learning materials, design and implement formative evaluation, and revising instructional materials. The trial in this study conducted in SMP 19 Pilot Banda Aceh. The result showed that the learning device geometry with Cabri 3D-assisted RME approach memenui valid criteria, practical andeffective.

Abstract

The result of PISA and TIMSS showed that students' mathematics abilities Indonesia is still low, including the ability to think creatively. The ability to think creatively influenced by psychological factors, one of them is anxiety. The efforts that teachers can do to improve creative thinking and coping with anxiety is applying problem posing approach. The problem posing approach can make students creative in issuing ideas to create questions and resolve them through three forms of cognitive activity, namely: presolution posing, within solution posing and posing post solution, then it ramble positive anxiety of students in learning. This study aims to determine the increase in the mathematics creative thinking ability and changes anxiety in learning by using problem posing approach. The study uses a quantitative approach to the type of experimental design pretest-posttest control group. The collecting data by using mathematics creative thinking ability tests and questionnaires anxiety. The data were analyzed using t-test and Two Way Anova. The results showed that the overall increase in the mathematical creative thinking ability of students taught through problem posing approach better than students taught through conventional learning. The same is also happened for students with medium and low KAM. As for students with high KAM increase creative thinking abilities of students taught through problem posing approach is no better than students taught through conventional learning. The results also show that there is no interaction between the learning and human factors to improving the students' ability to think creatively. In addition, overall there is a decrease both anxiety in students being taught by problem posing as well as conventional, as the decrease of anxiety in intention is the decrease of anxiety with ideal criteria. The decrease anxiety in students taught with problem posing better than conventional students. It also happens to students with high and medium.

Abstract

Reasoning in mastering the foundations of mathematics and mathematical competence is one that should be owned by students. While a model of discovery learning is one of the models of learning that must be applied at school in accordance with the curriculum learning goals of 2013, the purpose of this research was to describe the mathematical reasoning abilities of students through a model of discovery learning. The research method used was a qualitative exploratory type approach. The data has been obtained through mathematical reasoning tests and interviews. The result of this study is: 1) High ability students only mastered the indicator to propose allegations. The ability to file allegations limited to the ability to estimate answers with the reasons but the evidence provided was not appropriate; 2) Medium-capacity students only mastered the indicator to propose allegations. Ability to file allegations limited to the ability to estimate answers with the reasons but the evidence provided was not appropriate; 3) Low ability students could not master the six indicators of mathematical reasoning ability. In the indicator of filing suspicion, students estimated answers together with the reasons through trial and error, and students did not know the supporting concepts used in showing evidence. Student?s inability in mathematical reasoning was caused by the inability to master the concept correctly as well as not able to understand the problem and to provide evidence in solving the problem. Therefore, the application of discovery learning should be carried out continuously and consistently so that students can develop reasoning abilities well.Keywords: mathematical reasoning, discovery learning.
