摘要：This study aims to develop thermal length expansion practicum sets that are expected to
improve high-school science process skills (SPS) in expansion material on metal rods. This
research was conducted at SMAN 2 Bekasi in class XI by comparing the control and the
experimental class. This study uses the ADDIE approach to analyze, design, develop,
implement, and evaluate the thermal expansion length practicum sets. The feasibility test of
this practicum sets was carried out in two ways: conducting experiments and validating tests
from experts. The experimental results for the linear expansion coefficient of an iron bar are
3.09%, the brass is 5.81%, and the aluminum is 7.39% from the reference value. All of the
experimental data still below the error acceptance level which is below 10%. The validation
results give 85.5% from media experts and 86.1% from material experts. The trials on users
obtained 93.9% of teachers and 85.4% of students. The N-gain in control and experiment class
then compared to see the increase in SPS in each category. There was an increase in the
experimental class SPS value 7.3% higher than the control class, where the SPS value in the
experimental class increased by 47.8%. Therefore, it can conclude that the thermal expansion
practicum sets is feasible to use and can improve the science process skills of high school
students.
