摘要:This research aimed at examining the effectiveness of collaboration of Jigsaw and
problem-based learning (PBL) model in developing students’ critical thinking
skills. This research exerted an experimental design using pre-experimental one
group pretest-posttest. The implementation of such model collaboration was
carried out in SMK Batik 1 Surakarta, Central Java, Indonesia by engaging 37
accounting students of class XI. Before and after the implementation of the twomodel
collaboration, the students were given the tests of critical thinking skills
which were set in the same composition. The research data were in the form of
pretest and posttest scores which were analyzed by examining t-test and gain score
whose calculation was assisted by SPSS 23 program. The result indicated that
there was a difference between the pretest score and the posttest score with the
significance level of 0,000 < 0,05. The average of pretest and posttest scores
respectively referred to 48,44 and 68,93. Accordingly, the implementation of
collaboration of Jigsaw and problem-based learning (PBL) model was effective in
developing students’ critical thinking skills. From this research finding, there was
an impediment of time limitation in enacting the collaboration of the two models.
This constraint happened while presenting the result of group discussion.
