台州市基础教育阶段师资需求预测

20世纪80年代后期,台州市出现了一次生育高峰,这使得“十五”期间台州市基础教育学龄人口在数量和结构上出现了超常规的波动。此波动对21世纪初台州市基础教育发展产生了一定的影响,在基础教育的不同阶段,师资的需求规模、速度和层次等方面都将发生很大变化,“十五”期间台州市师范教育发展的思路需要作出适当的调整。     

Selection for special education services: the role of gender and socio-economic status

Children from some demographic groups disproportionately receive special education (SE) services. Due to methodological shortcoming in existing work, it remains unclear whether this is due to real differences in academic needs or cultural selection/bias. Hence, in a community sample of 1250 Norwegian children, we examined the role of third grade SE services, academic test scores, behavioural problems, and teacher’s level of helplessness in mediating the effect of family socio-economic status (SES) and students’ gender on fifth-grade SE services. Results revealed no direct effects of either gender or SES on fifth-grade SE, but four mediated pathways were identified: (1) Boys had a greater likelihood of receiving fifth-grade SE services when (a) they previously received SE and (b) they experienced more ADHD symptoms, both in third grade. (2) Students from low-SES families were more likely to receive SE services in fifth grade when (a) they performed poorly in math in third grade and (b) their teacher reported greater feelings of helplessness when teaching these students. The findings are discussed with respect to the differential-needs hypothesis, mechanisms of cultural selection and the possibility of gendered selection for SE at younger ages.

Science in the Trenches: An Exploration of Four Pre-service Teachers' First Attempts at Teaching Science in the Classroom

This paper explores four students' attempts at teaching science in the real world classroom during their initial student teaching practicum, including their struggles and successes. When pre-service teachers enter their initial practicum experience they are confronted with differing teaching philosophies of their own, their university professors, and their school mentors (Sullivan, Mousley & Gervasioni, 2000; John, 2001; Fu and Shelton, 2002). Within this situation, preservice teachers struggle to find their own niche of teaching science and learn to reflect as both learner and teacher (Kelly, 2000). Our goal as science teacher educators is to help pre-service teachers have an easy transfer from personal university experiences to teaching science in the real classroom environment while maintaining the integrity of newly learned teaching strategies (Segall, 2001). This work adds to and helps guide science teacher educators in identifying difficulties pre-service teachers' experiences in the transition from methods courses to practice.
