TPACK-Based Project-Based Learning Model Development to Improve the Four C’s Students’ Skills

This research aims: 1) to know the description of the needs of the TPACK-based PjBL model; 2) to produce a TPACK-based PjBL model design; 3) to know the feasibility of developing a TPACK-based PjBL model; 4) to know the practicality of the TPACK-based PjBL model; 5) to know the effectiveness of the TPACK-based PjBL model to improve the Four Cs skills of PGSD students at Muhammadiyah University Enrekang. The research and development design uses the Plomp model which consists of preliminary research, prototyping phase, assessment phase. The data collection techniques used were Questionnaire Techniques, and Observation. The research instrument used a learning device validation sheet, a learning implementation observation instrument, a student response instrument, a four Cs skills assessment instrument. The results showed that it was necessary to develop a TPACK-based PjBL model to improve students' four Cs skills. The design of the PjBL-TPACK model in the form of a model book, SAP, LKM, and several research instruments was declared very valid based on expert judgment. The results of the practicality test showed that the TPACK-based PjBL model was proven to be very good, based on the results of observation and implementation of learning and student response questionnaires. Furthermore, the results of the effectiveness test through the assessment of students' four Cs skills show that there is a significant difference in the application of the PjBL model with the TPACK-based PjBL model on four cs skills between PGSD class A students and PGSD class B students.
