Abstract
This study examined public junior high school science teachers’ technological, pedagogical, and content knowledge (TPACK) and instructional challenges. It aimed to determine the TPACK profile of the respondents and the challenges they encounter in teaching. This study was conducted in seven public junior high schools with 35 respondents in the Division of Cabanatuan City. It used a descriptive-correlational research design, including a survey questionnaire and data analysis using descriptive and inferential statistics. The findings revealed that the teachers have very satisfactory TPACK, with technological and content knowledge scoring highly and pedagogical knowledge outstanding in some areas. Challenges included insufficient training, lack of learning materials, and inadequate infrastructure, though respondents did not struggle with understanding science concepts. Teachers also reported issues such as insufficient preparation for laboratory activities, difficulties engaging students in discussions, and challenges in assessing students’ capabilities. Significant relationships were found between respondents’ age and instructional challenges with TPACK. Additionally, age and years of experience were significantly related to instructional challenges. The findings highlight the need for improved teacher training and resources to enhance instructional practices and support effective science education. This study provides valuable insights into the current state of science education in Cabanatuan City, offering a framework to improve teacher competencies through targeted training and resource provision. This may guide educational stakeholders in designing interventions to enhance teacher performance and foster a more engaging and supportive learning environment for students.
