Evaluation Approache
In this study, the research problem was: “Is the computer based physics instruction as effective as laboratory intensive physics instruction with regards to academic success on electric circuits 9th grade students?” For this research of experimental quality the design of pre-test and post-test are applied with an experiment and a control group.

Levels of evaluation

The study is applied in student level , on 9th graders of a secondary school in a
Azdavay district of Kastamonu province in Turkey.


Techniques

A design of pre and post tests is applied to the experiment and control groups as a research method ,

The research group is made up of a total of 28 students , surveys ( CLIS Survey, PLIS Survey applied to a different group of 40 students ) were conducted to determine the level of students’ interests and according to survey results, students are distributed in the groups .

In order to evaluate and determine the suitability of the selected number of software two physics teachers and two academicians that are expert in their own fields were requested to examine such software. the program of Edison 4.0 was chosen as a lesson software.

First, for the experiment / control group of 14 students whose interests are the same for computer and physics labs an Electrical Circuits Achievement Test (ECST) as a pre-test was given. Later on, for a 4 -week period the computer lab of the school was changed into the Physics Lab one day in a week and was changed into the Computer lab another day in a week and the application was conducted this way.
