The science achievement of 226 5th graders from districts that have a kit-based inquiry science curriculum supported by intensive professional development (PD) is compared with data from a group of 173 5th graders from other districts that use nonkit science materials and do not have systematic science PD for teachers. Within the kit-based project, the sample of project teachers is stratified to select teachers with a high number of science PD hours versus those with few hours. While there were no significant differences in the mean total scores for kit-based students with low PD versus high PD teachers, the kit-based classrooms scored significantly higher than students in nonkit classrooms on both the pretest and posttest, though there were significantly more minutes of science instruction in the nonkit classrooms. Finally, nonkit teachers taught more units of shorter length and reported lower levels of preparedness to use reform pedagogical approaches.  相似文献

This study investigates the dialogic processes involved in how teachers talk about their students and what consequences their ways of talking (i.e., “narratives”) may have for their guidance. We take a sociocultural perspective on learning as transformation of students’ subjectivity. Teaching, as a process of guiding and facilitating learning, cannot be effective if the teacher does not actively seek how the student perceives and understands reality. We borrow and adapt from Bakhtin (1999) four narrative ways of talking about others: objectivizing, subjectivizing, problematizing and finalizing. The presence of these narratives in web discussion postings of our pre-service teachers about the Latino children they worked with in a community center are analyzed. We then compare their ways of talking about children with print- and web-based discussions about children made by in-service teachers, model teachers and our pre-service teachers in a school-based practicum. Using mixed quantitative and qualitative methodologies, we found an overwhelming predominance of objectivizing and finalizing in our pre-service teachers’ narratives about the children with whom they work that seems to define a certain pedagogical regime that we call here “teaching imaginary children/students.” This “way of talking” about children seems to be characterized by unchecked speculations guiding instruction that are not tested by finding out from the children themselves how they understand the instruction and the world. These speculations, in turn, can lead to a dogmatic approach towards children.  相似文献

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。  相似文献

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.  相似文献

The first year of a 5 year professional development project for elementary teachers in two mid-western states integrated a bridge of two distinctly different distance education networks (T-1 and fiber optics) to provide science professional development for elementary school teachers in rural communities. Interactive television (ITV), the title given to the distance component, consisted of a series of twenty-four, 2 h presentations by scientists and content specialists. It provided expansion to the science pedagogical content knowledge of the elementary teachers involved. Eighty-five teachers in 38 school districts from the two states completed individual surveys following the final ITV session. Analysis of variance of participants post-session survey scores yielded differences (p < 0.05) on the subscales measuring perceived effectiveness of using distance education for professional development purposes and years of teaching experience. Teachers with over 20 years of classroom experience perceived the use of distance education technologies for science professional development to be more effective than teachers with 16–20 years of classroom experience. These results might suggest another digital divide.  相似文献
