The data of this study was collected through a questionnaire designed to measure teachers' ability to integrate technology, pedagogy, and content knowledge (TPCK) in teaching green energy topics. The questionnaire consisted of 25 items of statements based on a 5-point Likert scale, ranging from "Strongly Disagree" to "Strongly Agree". This instrument includes three main components of TPCK, namely:
1. Technological Knowledge (TK): Measuring teachers' ability to understand and use technology to support learning.
2. Technological Pedagogical Knowledge (TPK): Assesses teachers' ability to integrate technology into effective learning strategies.
3. Technological Content Knowledge (TCK): Examines teachers' ability to relate technology to learning materials, especially green energy topics.
This questionnaire was distributed online through the Google Forms platform, allowing participation from teachers in various regions. Prior to deployment, the validity and reliability of the instrument were tested using the Rasch analysis approach to ensure the accuracy and consistency of the measurements.
The respondents in this study consisted of 225 science teachers in Indonesia who were randomly selected. The data collected includes demographic information such as gender, age, teaching experience, and recent education level. This data was analyzed to assess the validity, reliability, and distribution of teachers' abilities in integrating technology into green energy learning.
