Abstract

This study describes the application of guided discovery which improves students' mathematical reasoning in the Linear Program material. This study uses a qualitative approach with the type of Classroom Action Research (PTK). This PTK is implemented in Class XI TPM 3 SMKN 1 Madiun. The application of guided discovery is carried out in four stages. Introduction and Review, namely the teacher conditions students to be ready to learn by conveying learning objectives, explaining the benefits, and reminding the prerequisite material. The Open Stage, in which the teacher sets the group, then the students observe the examples, ask questions, and write down the characteristics of the concept based on the observations. Convergent Stage, where the teacher presents the problem, then students make assumptions, collect information, perform mathematical manipulation, conclude problem solving, re-examine problem solving, and present the results of the discussion. Closing and application, namely the teacher emphasizes important things, the teacher guides students to make conclusions and reflects, then the students work on the quiz. The results showed an increase in students' mathematical reasoning abilities in solving Linear Program problems. Students also gave positive responses to guided discovery learning.Keywords: guided discovery, mathematical reasoning, Linear Program

Abstract

Mathematical communication is the ability to convey mathematical ideas both verbally (orally) and in writing (in writing). Mathematical communication is a standard process that should be one of the focuses of teachers' attention in mathematics learning. One way to develop students' mathematical communication is to train students to work on open-ended questions and carry out activities related to these abilities. Open-ended questions give students the opportunity to explore their ideas and thoughts in solving a problem. This study aims to describe students' mathematical communication in solving open-ended questions on Statistics material. This research uses QCAI mathematical communication criteria in the QUASAR Project and relates it to the problem solving theory according to Polya. The data were obtained through students' answers after giving open-ended questions to students. The research subjects were 3 students who were selected from groups of high, medium, and low cognitive levels. S1 gives a response by writing 15 kinds of correct answers, S2 and S3 only write down only one kind of correct answer. Subjects have various mathematical communication and their own ways of how to communicate their answers effectively to others and provide strong arguments that support their answers both orally and in writing.

Abstract

This research aims to describe creativity students in solving geometry problems in Junior High School. This research is explorative-qualitative. The research subjects are 3 students of the grade VIII of Junior High School who has high, moderate and low ability. The subjects were chosen by purposive sampling. This research result show that students who has high, moderate, and low ability tend to be fluent in problem-solving but are not flexible and lack of novelty in solving geometry problems.
