This research aims to: 1) Analyze the influence of social science learning
using the Problem Based Learning model assisted by audio-visual media in social
science lessons on Human Digestive System Disorders on learning motivation; 2)
Analyzing the influence of social science learning using the Problem Based
Learning model assisted by audio-visual media in science and science lessons on
Human Digestive System Disorders on critical thinking skills; 3) Analyzing the
relationship between motivation and critical thinking skills of students using the
Problem Based Learning model assisted by audio-visual media in science and
science lessons on Human Digestive System Disorders.
This research uses a quantitative approach and uses a quasi-experimental type
of research. Data collection techniques use tests and documentation. Meanwhile,
the data analysis technique used is prerequisite testing and hypothesis testing using
the t-test.
The results of this research are: 1) the Problem Based Learning model
assisted by audio-visual media provides a positive significant influence on learning
motivation in science and science lessons on Human Digestive System Disorders;
2) the Problem Based Learning model assisted by audio-visual media provides a
positive significant influence on critical thinking skills in science and science
lessons on Human Digestive SystemDisorders; 3) Learning motivation and critical
thinking skills have a strong correlation.
