Schmid, Brianza, and Petko develop TPACK.xs, a concise self-report instrument for teachers’ technological pedagogical content knowledge. Existing questionnaires were often lengthy, difficult to use, or psychometrically ambiguous.
The authors generate and refine items representing technological, pedagogical, and content knowledge and their intersections, then test the scale with preservice teachers. Reliability and confirmatory factor analyses support a short instrument that can be administered economically. The study also compares two conceptions of TPACK: an integrative model in which component knowledge domains remain distinguishable and combine, and a transformative model in which TPACK functions as a more unified competence. Results provide stronger support for the integrative structure in this sample.
Because scores are self-reports, they indicate perceived knowledge rather than direct classroom performance, and the factor solution needs replication across populations, subjects, and languages. For researchers and teacher educators, TPACK.xs offers a practical diagnostic or programme-evaluation measure, best supplemented with lesson plans, observations, performance tasks, or portfolios when claims concern enacted technology integration.
A transparent research trail
Each entry identifies the volume, edition, chapter or appendix in which the work appears.
Evidence summaries explain the central idea and why the source matters to educators.
Entries link to lawful full text where available, or to a publisher, library or purchase page.
References are checked against publisher records, scholarly indexes, DOI or ISBN metadata, repositories and author records where available. An entry marked [Citation not verified] preserves the wording found in the relevant volume without attributing findings to an unconfirmed work.
