摘要：AbstractFreeware open source authoring tools are available and easily attainable over the internet for teachers to develop their own interactive instruction. This study investigated the effects of interactive exercises developed using the open source authoring tool on students’ achievement using the pre-test post-test with the control group research design with 35 seventh grade students in the Science and Technology course. Findings showed that the use of interactive exercises embedded in the instruction improves the achievement of students more than the instruction having traditional exercises. Further research should compare the effects of interactive exercises completed individually and in a group format.
