Abstract

The purpose of this research was to make learning media in a kind of Van de Graaff Generator to explain the static electric concept. The stages of this research were designing, making, and testing the effectiveness of Van de Graaff Generator. The making of Van de Graaff generator used simple devices and materials that have already available in local market, such as steel ball, electric motor, elastic belt, metal brush, and DC power supply. The testing was done qualitatively and semi qualitatively to the contents of the ball by measuring the voltage of the ground-ball. The maximum voltage ball is 942V which was produced from entry voltage on the strengthener series 6V, with the motor voltage 18V. The Van de Graaff generator can be made as learning media because can prove the existence of gathered charges at the ball.

Abstract

This research purpose to analyze effective usage of the media in the course of study and also know student response to usage of the appliance. This subject of the research was the students of XB Class of SMA 12 Pekanbaru consist of 44 students. Compiler data instrument in the form of the test result of learning to see the effectiveness of the appliance and questionnaire to know efficiency and also student response to the appliance. In analyzing data used by descriptive analysis and analysis usage of alternative media for the study of wave and optic in class XB. From data analysis obtained by usage of physics appliance effective enough where mean student absorption 74,70 %, while physic appliance efficiency resides in a high category with the mean score as a whole is 4,01. While the analysis of usage of media can be categorized is effective, although done by activity is the student cannot in perceiving directly, because of the limitation of time in study. So that more student work and can do experiments at home by teaming.

Abstract

The purpose of this research has described learning result of physics science skill process by applying kontextual learning. The subject of this research is 25 students of SMAN 1 Pangkalan Lesung. Data is collected by giving the applicative process test after finishing the subject. Data analysis showed that abortive power is with good category, learning effectiveness can be caregorized in effective, but completeness of students learns is not complete. So, the kontextual learning is clafified effective for science process skill achievment of second year students at SMAN 1 Pangkalan Lesung.

Abstract

This study aimed to examine the effectiveness cognitive aspects of learning through the implementation the NHT Quiz-XA grade students at SMAN 12 Pekanbaru on subject matter the electrical circuit and Kirchoff Law in the academic year 2008/2009. The subjects were students of class XA 12 Pekanbaru SMA 2008/2009 school year which amounted to 41 students. Data collection instrument is flat assessment of cognitive achievement test. Data were analyzed using descriptive analysis techniques, including aspects relevant to the subject matter and the characteristic of students. Results of data analysis shows that subject matter mastery of 91.7% with a complete mastery category by category relevance is very high and classical mastery learning students is 87.8% with a category of exhaustiveness is finished with high relevance category, learning effectiveness of students categorized as effective.
