Professional knowledge or motivation? Investigating the role of teachers’ expertise on the quality of technology-enhanced lesson plans

In an expertise study with 94 mathematics teachers varying in their relative teacher expertise (i.e., student teachers, trainee teachers, in-service teachers), we examined effects of teachers' professional knowledge and motivational beliefs on their ability to integrate technology within a lesson plan scenario. Therefore, we assessed teachers' professional knowledge (i.e., content knowledge, pedagogical content knowledge, technological knowledge), and their motivational beliefs (i.e., self-efficacy, utility-value). Furthermore, teachers were asked to develop a lesson plan for introducing the Pythagorean theorem to secondary students. Lesson plans by advanced teachers (i.e., trainee teachers, in-service teachers) comprised higher levels of instructional quality and technology exploitation than the ones of novice teachers (i.e., pre-service teachers). The effect of expertise was mediated by teachers' perceived utility-value of educational technology, but not by their professional knowledge. These findings suggest that teachers’ motivational beliefs play a crucial role for effectively applying technology in mathematics instruction.

Reconceptualising educational assessment in South Africa — testing times for teachers

This paper explores some of the problems arising when Continuous Assessment (CA) is grafted onto established pedagogic practices. It focuses on three issues: teachers' restricted understandings of assessment, teachers' emphasis on criteria that demonstrate concern with social control, and some of the problems connected with peer assessment. Two vignettes derived from fieldwork associated with a project to improve the quality of primary education are used to raise the issues. We argue that the development of desired practices is hampered above all by tacit values in tension with those underpinning the new curriculum. These values, together with the complexity of curriculum design, create serious problems of manageability and interpretation, which can only be addressed through detailed interactive in-service training, aimed at reconceptualising teachers' notions of assessment.
