The method used is an experimental design with a pretest-posttest control group design. The sampling technique used cluster random sampling and the technique of data collection through tests in the form of essays. The result of the research showed that there were differences in learning outcomes of students whose learning uses the Probing Prompting Learning Model and learning outcomes of students whose learning uses the direct Learning Model, whereas learning outcomes of students whose learning uses the Probing Prompting Learning Model were higher than learning outcomes of students whose learning uses direct Learning Model in Rectangular Topic. ...

This study aimed to describe the visualization process of junior high school students in solving geometry problems viewed from gender differences. The description of the student visualization process was based on the aspects of generation, inspection, transformation, and use. The methods of data collection in this study were conducted through test and interview. The result of the research showed that in generation aspect, male and female students made the picture according to the information of the problem which was given by relating it to the knowledge they had. In inspection aspect, male and female students applied the rules of Pythagoras theorem to determine one of its elements. In transformation aspect, female student changed the pattern of visual ideas into square shapes by translating the elements, while male student changed the pattern of visual ideas into triangular shapes. In use aspect, female student used a picture to check the result of the operation, while the male student did not use a picture to check the result of the operation. Thus, this visualization process was expected to provide information for teachers about the visualization process of junior high school students either male or female so as to assist teachers in designing learning.

Oleh karena itu, penelitian ini merupakan penelitian deskriptif yang bertujuan untuk mendeskripsikan efektivitas pembelajaran dengan pendekatan Problem-Centered Learning (PCL) pada materi Teorema Pythagoras di kelas VIII SMP yang ditinjau dari 4 indikator, yaitu: kemampuan guru mengelola pembelajaran dengan pendekatan PCL, aktivitas siswa selama mengikuti pembelajaran dengan pendekatan PCL, ketuntasan belajar siswa, dan respons siswa setelah mengikuti pembelajaran dengan pendekatan PCL. Sumber data dalam penelitian ini berasal dari subjek penelitian yang terdiri dari peserta didik kelas VIII SMP Negeri 1 Kota Gorontalo tahun ajaran 2014/2015 yang berjumlah 23 peserta didik, guru yang melaksanakan proses pembelajaran dengan pendekatan PCL (Problem-Centered Learning), dan untuk observasi melalui lembar pengamatan dipilih 5 orang peserta didik unt...

This study was quantitative descriptive. In this study, the effectiveness of learning through Problem-Centered Learning (PCL) approach on the subject of the Pythagorean Theorem based on teacher’s ability is managed learned through Problem-Centered Learning approach, student’s activities during learning through Problem-Centered Learning approach, student’s response after the following learning through Problem-Centered Learning approach, and student’s learned achievement. The data collection methods in this study were conducted through observation with observed sheets, tests, and questionnaires. The result of the research showed that learned through the Problem-Centered Learning approach on the Pythagorean Theorem subject was effective. This can be shown from Every aspect of the teacher’s ability to learn through the Problem-Centered Learni...
