METHODOLOGY
This study intended to solve practical problems in
teaching-learning that need to be remedied crucially
through class action [12]. The class action steps consist of
learning investigation, an action plan, assessment, and
treatment. To prove the purpose of the research, it needs to
determine the research elements, including the subject, the
research variables, and how to analyze the data.
A. Subject
Based on the investigation and evaluation of problembased
learning in medical school, it is known that the
lowest graduation number is in alimentary block compared
to other blocks. Thus, the research samples were
249 students of alimentary block. The students who are
willing use CAL module as the experimental group and
other students are entering as a control group.
B. Variables
The research variables consisted of analytical skill of
students as dependent variable and the effect of step-bystep
instructional learning as independent variables. The
analytical skill obtained at the end of the course indicated
by a score of CAL. The independent variable of CAL
based on the nine steps Gagne's instructional.
C. Method
The research divided into four steps “Fig. 1”: requirements,
structures, core, and the result. The research has a
goal to implement CAL in PBL using Gagne's Instructional
Design to enhance the analytical skill of students as
indicated by an increase in test grade. The structure of the
research includes the design, implementation, and evaluation.
D. Analysis
This research is a classroom action research for the development
of a learning model, so that uses descriptive
qualitative analysis. The effectiveness of the CAL model
for student analysis ability performed using t-test and
effect size calculation.
