摘要：The purpose of this research was to know the effect of blended learning strategy
on learning achievement and science process skills of students in plant tissue
culture course in the Universitas Negeri Medan. The research method was quasi
experiment. The population of this study was all semester VIII students of biology
education program. The study sample consists of two classes, namely: class A
known as control class who were taught by conventional learning strategy and class
C known as experiment class who were taught by blended learning strategy. They
were selected using cluster random sampling technique. The results of the study
showed that tcount = 3.769, P= 0.001 at the level significance of 0.05 in learning
achievements score. It also showed that tcount = 5.435 > ttable = 1.661 P= 0.001
at the level significance of 0.05 in science process skills score. Based on the study
result, it can be concluded the blended learning strategy found significantly more
effective in enhancing students’ learning achievement and science process skills in
plant tissue culture course as compared to the conventional learning strategy.
