Problem Based LearningAbstract
- This research is classroom action research which aims to determine descriptions of
teacher activities, student activities, and the ability to solve mathematical problems
in applying the PBL learning model to improve the ability to solve mathematical
problems in fourth grade students at SD Negeri 101 Pajalesang. The subjects in this
research were all 12 fourth grade students and fourth grade homeroom teachers. Data
collection techniques use observation and tests. The data analysis techniques in this
research are data reduction, data presentation and drawing conclusions. The research
results show that teacher activities in managing learning experienced an increase in
the optimal learning process from cycle I to cycle II based on teacher activities in
implementing good learning designs according to the steps of the PBL learning model
to improve the ability to solve mathematical problems. Student activity in
participating in the learning process increased from cycle I to cycle II based on the
results of observations during the learning process using observation sheets. As for
the ability to solve students mathematical problems in cycle I, there were 5 out of 12
students who completed it with an average score of 67,66 with a percentage of student
learning completeness of 42% (enough), while the ability to solve students
mathematical problems in cycle II there were 10 out of 12 students who achieved a
complete score with an average score of 79,91 with a percentage of student learning
completeness reaching 83% (good). It can be concluded that the PBL learning model
is to improve students ability to solve mathematical problems. 8
