Abstract The ability to integrate technology in learning, also known as Technological Pedagogical Content Knowledge (TPCK), is one of the competencies that teachers must master in the era of the Industrial Revolution 4.0. TPCK can be prepared when a teacher becomes a pre-service teacher at a university. The goal of this study was to describe the impact of Project-Based Learning (PjBL) on TPCK in elementary school pre-service teachers. This study is an experiment with a poor experimental method. The design applied is a one-group pretest-posttest design. The sample of this research is pre-service teachers or elementary school teacher education students as many as 94 students. Data collection instruments to measure TPCK are questionnaires and assessment sheets. The questionnaire was used to measure TK, PK, CK, TCK, PCK, and TPK. The assessment is used to measure TPCK. TPCK is assessed using the outcomes of student-created learning materials. The data is analyzed using descriptive statistics and inferential statistics. To describe the distribution of TPCK data, descriptive statistics are used. To test the study hypotheses, inferential statistics are used. The paired sample t-test was used to test the hypothesis. The descriptive analysis results suggest that the TPCK for pre-service teachers is in the high range. The hypothesis test results demonstrate that PjBL improves the TPCK of pre-service elementary school teachers. These findings highlighted PjBL's potential for TPCK development.
