The industrial revolution 4.0 has become a major topic especially in the field of
education. Education needs to provide the right response in accordance with the
times. School learning should facilitate students in developing their abilities. The
abilities that need to be developed include creative thinking and collaboration.
Teachers need to make innovations in learning activities, one of which is using the
Prob-Pro BL Model to develop students' creative thinking and collaboration skills.
This research used Quasi experimental method with posttest-only control group
design. The subjects of this study were 4th grade students at SDN 2 Karangtalun
Kidul (control class) and 4th grade students at SDN Kaliurip (experimental
class). The samples were taken using cluster random sampling technique. Data
collection techniques used tests and observations. The data analysis technique
used the Mann Whitney Test because the data was not normally distributed in the
normality test results. The results of this study showed that 1) The Prob-Pro BL
model has a positive effect on the creative thinking skills of elementary school
students in learning substance material and its changes. This result is obtained
from the significance value of 0.00 <0.05. 2) The Prob-Pro BL model also has a
positive effect on the collaboration skills of elementary school students in learning
substance material and its changes This result is obtained from a significance
value of 0.00 <0.05. The use of the Prob-Pro BL Model in elementary schools is
highly recommended because it is easily adapted by teachers and can use simple
equipment so that it does not burden the school.
