Abstract

The optimum portion of learning activities of students in a learning becomes urgent given to students, with the ultimate goal of obtaining the expected learning outcomes. However, the reality that occurs, the learning process often marginalizes the activities of students, one of the causes of this problem is the learning process that is fixed on the old pattern, namely the one-way learning process, from the teacher to the students, the teacher carries out learning by ignoring the optimization of participants' learning activities students, learning activities of students are only limited to listening and or taking notes. In other words, the teacher is active while the child is receptive. So that learning outcomes are expected to be at a low level or may not be achieved at all. This research is a Classroom Action Research (CAR/PTK), PTK is defined as a teacher's measured and systematic effort to solve problems that arise in learning events in his class, as well as to determine the quality of the process and learning outcomes of students. Solving these problems is done inclusive in the implementation of learning that is practical, situational, conditional, and contextual. The conclusion of this study is that cooperative model of TPS type can relatively improve student learning activities, cooperative model of TPS type can relatively improve student learning outcomes, and learning by using cooperative model of TPS type obtain positive responses from students.

Abstract

This research motivited by the low of students' mathematical problem solving abilities. The one of alternative learning thatis applied to improve the mathematical problem solving ability of students by using Open-ended approach. The purpose ofthis research was to find out whether there were differences in the improvement of mathematical problem solving abilitiesbetween students using Open-ended approach and students used the Problem-Based Learning model, as well as knowing thestudents' self-concept of mathematics learning with the Open-ended approach. The method was used in this study is a quasiexperimentalmethod, with a pretest-posttest control group design research. The study was conducted in one of the junior highschools in Bandung Regency. The population in this study were all seventh grade students of one of the junior high schoolsin Bandung Regency, while the samples were students of class VII-A as an experimental class and class VII-D as a controlclass. The experimental class is treated with Open-ended approach and the control class is treated with Problem-BasedLearning model. The instrument were a mathematical problem solving ability test, student questionnaire and teacherobservation sheet. In this study quantitative and qualitative data were obtained. Based on the analysis of the results ofmathematical problem solving tests, the conclusion is the improvement of students' problem solving ability using the Openendedapproach is no better than the students who use the Problem-Based Learning model in mathematics learning. Althoughthe improvement of problem solving in experimental class students is not better than control class students, but at least theOpen-ended approach has a positive effect on students' self-concept.

Abstract

This research study is motivated by assessments in study groups that tended to be an individual assessment to each student, which resulted to the lack of students’ motivation to teach their friends in the groups who do not understand the material, so the discussion process in learning is less effective. The purpose of this research study is to observe the pattern of effective assessment on the cooperative model learning in terms of student learning outcomes. The method used in this research is a qualitative descriptive method with a type of reflection research. The reflection is used to get feedback on the lessons learned, including: 1) Lesson reports 2) Surveys and questionnaires, 3) Audio and video recordings, 4) Observation. Data collection is done by tests, interviews, documentation and observations. The results of the study of previous studies obtained four models of assessment patterns; low levels students assessment pattern, medium levels students assessment pattern, group average assessment pattern, and individual assessment pattern. Based on the results of the analysis, this research study concludes that the effective assessment pattern in achieving learning objectives in cooperative learning is with the group average assessment model.

Abstract

This research is motivated by the mistakes that students did in solving the indefinite integral problems. Such mistakes might occur because of learning problems experienced by the learners. The purpose of this study is to examine the types of learning barriers experienced by learners in solving the indefinite integral problems. This research is a descriptive research with qualitative approach. The subjects of this study were the students of class XII who had experienced the indefinite integral problems. The subject was selected by a purposive sampling technique. The data were collected by using a triangulation technique. The findings showed that the LO experienced by the learners in solving the indefinite integral problems, were: (1) mistakenly understanding the association of derivatives with the indefinite integral, (2) being erroneous in deciphering the indefinite integral problems in the form of algebraic functions (polynomials, roots, and fractions) related to the operations, and (3) the students did not write “+c and dx” in integrating steps and integrating results. The LO focused on epistemological learning obstacle.
