caused students directed to develop critical thinking
skills through direct learning in solving accounting
problems. By direct learning, students are required to
solve accounting problems independently so as to
develop their critical thinking. This finding is in line
with previous research on the influence of learning
models in improving critical thinking skills.
4 CONCLUSIONS
Based on the findings in this study, it can be
concluded that the introduction of accounting lessons
through problem-based learning with scientific
approach can significantly improve students' thinking
skills in the medium category (N-gain = 0.59). The
highest critical thinking ability indicator is analyzing,
testing, and identifying accounting problems. While
the indicator of the lowest ability to think is to draw
conclusions, which presents the data and explain the
conclusions. The weakness of most students is
adjusting the adjusting journal, therefore for the next
researcher can develop the model of learning that can
make it easier for students to understand adjusting
journal.
