EFEKTIVITAS PENGGUNAAN PORTOFOLIO PADA PERKULIAHAN MIKROBIOLOGI TERHADAP KEMANDIRIAN DAN HASIL BELAJAR MAHASISWA
ABSTRACT: This research study
aimed to know the effectiveness of portfolio assessment in microbiology course
on students’ self-regulated and learning outcome. This research was the
experimental research of the pretes-posttest group design. The sample was 44
students of Nondik Biologi 2013. Self-regulated questionnaire and learning
outcome test were used to measure self-regulated and learning outcome of
students. Data were analyzed by using independent sample t-test with SPSS
statistics 21 program. The results show that: (1) Students’ self regulated
learning that assessed by portfolio bigger than assessed by paper test
(tcount=3,105, p<0,05), the average score of students’ regulated learning on
experimental class (score 81) > students on control class (score 76); (2)
Students’ learning outcome that assessed by portfolio higher than assessed by
paper test (tcount=2,861, p<0,05), the average score of students’ learning
outcome on experimental class (score 86) > students on control class (score
80); (3) Effect size portofolio assessment application on students’ self
regulated and learning outcome is 93%
dan 81%, for each. This study conclude that portfolio assessment application
effective on students’ self regulated and learning outcome in experimental
microbiology, State University of Medan.
