Keywords: hybrid
problem-based learning development model, critical thinking, problem-solving,
basic programming algorithm.
This
study aims to (1) describe the feasibility of the HyProBeL model that has been
developed; (2) describe the practicality of the HyProBeL model that has been
developed; and (3) describe the effectiveness of the HyProBeL model that has
been developed to improve students’ critical thinking and problem-solving
skills.
This
study employed the research and development (R&D) approach using the Borg
and Gall development models. The independent variable in the study is the
HyProBeL Learning Model, while the dependent variables are critical thinking
and problem-solving skills. The study involved a total of 60 students, with 30
students in the experimental class and 30 students in the control class.
This
research employed an experimental design with a pretest-post-test-only control
group. Data were collected using questionnaires and tests. The validity of the
critical thinking and problem-solving essay instruments was assessed using
Pearson correlation, while their reliability was tested using Cronbach's Alpha.
The normality test utilized the Shapiro-Wilk test, and the homogeneity test
employed the Levene test.
The
obtained results are as follows: the average validation of the HyProBeL
Learning Model, based on expert assessments, is 3.93, indicating highly valid results.
Consequently, it can be inferred that the HyProBeL Learning Model is suitable
for use in assessments. Based on expert observation, the practicality of the
HyProBeL learning model is 95%, with highly favorable outcomes. The
effectiveness of the HyProBeL learning model in enhancing critical thinking
skills is supported by a significant t-test result of 0.000. Furthermore, the
model has been found to improve problem-solving skills, as reflected in a
significant t-test result of 0.02. This demonstrates an increase in critical
thinking and problem-solving skills for students using the HyProBeL Learning
Model.
