The Effect of the Conceptual Understanding Procedures Learning Model and the Initial Ability towards the Biology Cognitive Competence of Students Grade X MIPA at SMAN 2 Padang

This study aims to determine the effect of the conceptual understanding procedures learning model towards students’ Biology cognitive competence. This study was a quasi-experimental research design with Randomized Control Posted Only Design. The population of this study was the students Grade X MIPA SMAN 2 Padang registered in the 2019/2020 academic year. The samples of this study were students Grade X MIPA 3 as the experimental class and Grade X MIPA 1 as the control class chosen by using a Purposive Sampling technique. The instrument used was in the form of posttest. The data of this study were analyzed by using the two-way ANNOVA test. The results revealed that there are significant differences between the experimental class and the control class which the results of the students’ cognitive competence from the experimental class were higher than the control class. The mean score of the students’ cognitive competence from the experimental class was 76, 92 and the control class was 72, 47. Thus, it can be concluded that the conceptual understanding procedures learning model can improve the students' Biology cognitive competence
