A significant challenge in studying formative assessment is the lack of suitable instruments for assessing teachers' formative assessment practices. This paper reports the development of the Teacher Formative Assessment Practice Scale (TFAPS) and its psychometric properties based on two samples of primary and secondary school teachers: one from Hong Kong (N = 449) and the other from Italy (N = 309). Exploratory factor analysis identified two distinct factors, including teacher-directed formative assessment (TdFA, six items) and student-directed formative assessment (SdFA, four items). The confirmatory factor analysis supported this two-factor structure. Rasch analysis provided further psychometric evidence regarding scale dimensionality and item quality. This study suggests that TFAPS is an appropriate instrument for assessing teachers' formative assessment practices, but the cultural influence on teachers' formative assessment practices should be noted in the applications of the instrument.

This study aims to establish a robust measurement to obtain a comprehensive understanding of perceptions of programming education (POPE) of teacher and principal groups. In this study, the POPE scale contains three dimensions: (a) understanding in programming (UP), (b) support for programming (SP), and (c) expectation of programming (EP). Self-reported questionnaires were administrated among 258 teachers and 229 principals. Multigroup analyses were used among the two groups. The results of measurement invariance tests show that configural and metric invariance are fully supported, and scalar invariance is partially supported, suggesting the factor structures, loadings, and most item intercepts of the POPE scale are equivalent across the groups examined. Implications of the study are discussed.
