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.

Does the Model of Language in the National Literacy Strategy Create Failure for Pupils from Differing Language Backgrounds?

The National Literacy Strategy (NLS) was introduced by the government in the wake of the hotly debated issue of falling educational standards in the UK. All schools were required to adopt the NLS Literacy Hour unless they could show their preferred programme would result in raised levels of achievement. My experience of delivering the Literacy Hour has been a process of adaptation to the needs of my pupils, who are drawn mainly from groups whose language backgrounds differ from that which is dominant in school. I have found that the requirements of NLS, together with many of the commercial resources used to teach it, are not appropriate for pupils from these groups and a question arose: is it the pupils who are in some way deficient or is it the approach and the resources being used? This article takes a case study of the use of a commercially produced resource to explore the model of language implicit in NLS, the kinds of resources it generates and the ways in which this creates failure in pupils from different language backgrounds. It then considers the New Literacy Studies and their implications for an alteration in our approach.
