Abstract
The 2013 curriculum requires teachers to learning with a scientific approach to ensure that they are student-centered. It is carried out because student-centered learning has been proven to help improve student achievement. An appropriate instructional package is needed and makes it easier for teachers and students to support the implementation of learning with the scientific approach. This study determines the effect of implementing an instrctional package with a scientific approach to students understanding of ecology^s basic concept. So this research was conducted with a quasi-experimental approach following a matching only pretest-posttest control group research design. Data regarding students^ understanding of the basic ecology concepts were collected thorough a pretes and posttest in a multiple choice test. Researchers analyzed data from the gain score of the control group and the experimental group using the t-test. The results of the t-test show that the t score : 4.704> critical value: 1.671, at = 0.005, which implies that there is a significant difference in the level of understanding amid the experimental group and the control group. Furthermore, seen from the effect size, it is evident that the instructional package^s application with the scientific approach has a large effect size with Eta squared = 0.28. In other words, the instructional package^s application with the scientific approach has an effect of 28% on increasing student^s understanding of basic ecological concepts.
