IMPROVEMENT OF STUDENT CRITICAL THINKING SKILLS WITH THE NATURAL PRODUCT MINI PROJECT LABORATORY LEARNING
ABSTRACT: This research aims
to investigate effect of learning using natural product mini project laboratory
on students’ critical thinking skills. The research was conducted on sixth
semester of 59 students of chemistry and chemistry education program from one
of the state universities in West Nusa Tenggara, Indonesia in 2012/2013. This
research revealed class where the student learn using natural product mini
project laboratory had more critical thinking skills than those using
verification laboratory. The average n-gain of critical thinking skills for
experiment class was 0.58 while for the control class was 0.37. The highest n-gain
in the experiment class was 0.70 for “deciding on an action (selecting criteria
to judge possible solutions) indicators”, while the smallest n-gain was 0.47
for “the making and judging value of judgments (balancing, weighing, and
deciding) indicators. We concluded that the natural product mini project
laboratory was better than verification laboratory in improving the students’
critical thinking skills.
