THE EFFECT OF APPLYING SCIENTIFIC APPROACH BY USING MNEMONIC TECHNIQUE INTO STUDENTS’ LEARNING OUTCOME AND RETENTION ON HUMAN REPRODUCTIVE SYSTEM TOPIC AT GRADE XI SCIENCE SMA N 5 MEDAN A.Y 2015/2016

The study aims to know the effect of student learning outcome and its
retention through using Scientific Approach by using mnemonic technique on
human reproductive system in class XI MIA SMA Negeri 5 Medan Academic
Year 2015/2016. The population of this research was all students in class XI MIA
SMA Negeri 5 Medan totaling 376 students. The sample was taken by using
purposive sampling and was obtained the sample for 37 students of mnemonic
class (XI MIA 7). The instrument of research was student’s learning outcome test
in multiple choice form consist of 30 questions which has been validited by
expert. The result of data analysis show that post test in mnemonic class (79.08)
and conventional class (70.59). After t-test was carried out by using significant
degree α = 0.05, it was obtained that tcount = 4.28 and ttable = 1.9935, so tcount > ttable
(4.28 > 1.9935). It means that there is significant difference between student
learning outcome for mnemonic class and conventional class. Then, for retention
test the result show that average value in mnemonic class (65.62) and
conventional class (42.97). After t-test was carried out by using significant degree
α = 0.05, it was obtained that tcount = 2.66 and ttable = 1.9935, so tcount (2.66) > ttable
(1.9935). It means that there is significant difference between students’ retention
in mnemonic class and conventional class. It was concluded that students’
learning outcome and retention is better using Scientific Approach by using
mnemonic technique than conventional class that taught without mnemonic
technique. This study conclude that teacher can use this technique to increase
students’ learning outcome and retention expecially on human reproductive
system topic in Biology subject matter.
