Constructing a multiple choice test to measure elementary school teachers' Pedagogical Content Knowledge of technology education.

This paper describes the construction and validation of a multiple choice test to measure elementary school teachers' Pedagogical Content Knowledge of technology education. Pedagogical Content Knowledge is generally accepted to be a crucial domain of teacher knowledge and is, therefore, an important research topic. Nonetheless, the current methods to examine this domain of teacher knowledge are labor-intensive and time-consuming, which implies small-scale studies and restricts generalization of the results. Hence, the challenge remains to construct an instrument that is time and labor-efficient. Together with a team of experts in the field of technology education a multiple choice test was constructed. The instrument was statistically validated in three steps (sub study 1, 2, and 3). The procedure followed to construct our test was proved to be effective. The results showed that it is possible to statistically validate the test when focusing on test-retest reliability.
