对贵州省黎平县“民族文化进课堂”工程的思考

随着各少数民族地区经济的发展,各民族之间的交往日趋频繁,各种外来文化涌入少数民族地区,这必然使少数民族文化传承受到了严重挑战。学校教育对少数民族文化传承应发挥主体作用,黎平县“民族文化进课堂”工程实施就是典型例子,它对中小学少数民族文化课程的设置、实施及评价作了初步的探讨,并取得了令人欣慰的成果。     

适应试讲和说课技能训练的微格教学改进模式

试讲和说课是教师应聘的主要环节。由于试讲和说课与微格教学有着极其相似的课堂情境,所以可用微格教学的方式对师范生进行试讲和说课技能的培训。在几年的培训实践中,我们逐步对常规微格教学各操作步骤作了相应的改进,初步建立了适应试讲和说课技能训练的微格教学新模式。     

Assessing and tracking students’ problem solving performances in anchored learning environments

The purpose of this randomized experiment was to compare the performance of high-, average-, and low-achieving middle school students who were assessed with parallel versions of a computer-based test (CBT) or a paper-pencil test (PPT). Tests delivered in interactive, immersive environments like the CBT may have the advantage of providing teachers with diagnostic tools that can lead to instruction tailored to the needs of students at different achievement levels. To test the feasibility of CBT, students were randomly assigned to the CBT or PPT test conditions to measure what they had learned from an instructional method called enhanced anchored math instruction. Both assessment methods showed that students benefited from instruction and differentiated students by achievement status. The navigation maps generated from the CBT revealed that the low-achieving students were able to navigate the test, spent about the same amount of time solving the subproblems as the more advanced students, and made use of the learning scaffolds.

Evaluating Assistive Technology in Early Childhood Education: The Use of a Concurrent Time Series Probe Approach

As assistive technology applications are increasingly implemented in early childhood settings for children who are at risk or who have disabilities, it is critical that teachers utilize observational approaches to determine whether targeted assistive technology-supported interventions make a difference in children’s learning. One structured strategy that employs observations and which has powerful child progress monitoring implications is the concurrent time series probe approach. Requiring multiple performance measures of a child engaged in a targeted task over time—both with and without a specific assistive technology device—the concurrent time series probe approach can be used to evaluate the effectiveness of assistive technology tools in supporting skill acquisition in the classroom. This approach is described in the context of a case study, with accompanying explanations of how to interpret data and make decisions regarding the effectiveness of the technology.     

Mapping as a tool for understanding the proceedings of an art class

This article presents a visual documentation tool for the observation of art classes. The documentation of an art class, like the documentation of any active class, is a complex task that requires focusing on clearly designated components. Quick structured sketching, as proposed here, is able to reflect varied simultaneous activities of teachers and students within specific learning environments, and enables triangulation with the customary means of documentation. The observations took place in 21 primary school and junior high art classes and the findings enabled the characterization of three different approaches implemented by the teachers.     

Capturing and Enhancing Science Teachers’ Professional Knowledge

This paper reports research from a three-year Australian science teacher professional learning project, the Science Teaching and Learning (STaL) Project, in which groups of science teacher participants (across years K – 12) worked with academics over a one-year period as teacher researchers. Through reflecting on their experiences within the STaL Project and collecting data from their classrooms related to specific science teaching concerns, teacher participants constructed cases around particular aspects of their professional learning. The cases that these participants developed elicited rich insights into their teaching and their students’ learning of science. This paper discusses how the cases were developed by the teacher researcher participants and uses exemplars as a way of illustrating the nature of the professional knowledge developed.

论课堂教学对无声语言的运用

课堂教学是运用语言的艺术,语言包括有声语言和无声语言。无声语言分学生无声语言和教师无声语言。在课堂教学中教师要善于运用无声语言。以调动学生的学习积极性,不断提高课堂教学效率。     

Teachers' approaches towards word problem solving: Elaborating or restricting the problem context

This contribution reports about a seven-month long video-based study in two regular Flemish sixth-grade mathematics classrooms. The focus is on teachers' approaches towards problem solving. In our analysis we distinguished between a paradigmatic-oriented (focus on the mathematical structure) and a narrative-oriented (focus on the contextual aspects of a problem) perspective on the problem-solving process. The findings have highlighted that the word problem-solving lessons were more dominated by a paradigmatic than a narrative approach and that interventions in which the relation between the mathematics structure and the realistic constraints of the problem context is addressed, were rare.
