| Abstract: | The study described in this paper investigated the degree of implementation of school-based assessment schemes for practical
science. An assessment scheme in Hong Kong was used as the context for the research. Five dimensions of implementation were
identified and a conceptual framework was built by breaking down each dimension into attributes and these into content areas.
The research method used in the study incorporated some modifications on most past designs in order to determine adequately
the construct validity of data and to examine any method-specific biases. Three measuring instruments (namely, a student questionnaire,
a teacher questionnaire and an observation schedule) were designed. The construct validity of student data was demonstrated
through confirmatory factor analysis and multitrait-multimethod analysis. Comparative analyses of students' perceptions, teacher
self-reports and independent observational data resulted in convergent findings for only three out of the ten attributes of
implementation. |
