基于建构主义理论的多媒体教学模式及教学设计

建构主义教学模式强调以学生为中心,视学生为认知的主体,是知识意义的主动建构,教师只对学生的意义建构起帮助和促进作用。本详细论述了建构主义学习理论下,当前多媒体教学的教学模式以及在此模式下的教学设计。提出一些思路指导教师利用现代教育技术按照一定的模式和方法进行教学,充分发挥教师的帮助、促进作用和调动学生的“主体”作用,达到“同化-顺应”的教学效果。

Learning on Campus and Learning at a Distance: A Randomized Instructional Experiment

To address a major methodological problem in the body of evidence on distance learning in postsecondary education, we conducted a randomized, true-experiment paired with a quasi-experiment. Community college students randomly assigned to receive instruction at a distance via a two-way interactive telecourse demonstrated learning equivalent to that of students assigned to on-campus, face-to-face instruction. However, students choosing to take the course via telecourse at remote sites had significantly higher course learning than either randomly assigned group. Such evidence suggests that the body of evidence on distance learning could be seriously confounded by learner self-selection.     

An invasion in the classroom: influence of an ill-structured innovation on instructional and epistemological beliefs

In this article, the actual impact on students' instructional and epistemological beliefs of systematic attempts to implement a problembased, collaborative and technologicallyrich learning environment in regular, internationallyspread, secondary school classrooms is described. Although the literature suggests that learning environments do affect both categories of beliefs, empirical evidence is currently limited. To study the effects of learning environments, classroombased learning environments were redesigned in various respects. The change entailed the implementation of a problembased, collaborative and technologicallyrich environment to replace the more regular contentdriven, teachercentred and textbookbased environment. The implementation of the innovation was hypothesised to result in a change of both the instructional and epistemological beliefs of students. Moreover, these beliefs were expected to evolve in the direction of the assumptions underlying the innovative environment. A classical pretest and posttest study resulted in the confirmation of the first hypothesis. However, for the second hypothesis, the opposite was found: students' beliefs strengthened in a direction that contradicts the basic principles underlying the designed environment. The study highlights that a poor implementation of potentially powerful learning environments can result in unexpected and even undesirable side effects.     

Classroom Practices for Context of Mathematics Word Problems

How do teachers conceptualize and deal with context of mathematics word problems in their teaching? This question is discussed based on a study of 14 experienced teachers at the elementary, junior high and senior high school levels. Bruner’s notions of paradigmatic and narrative modes of knowing formed the basis of analysis of data from sources that include interviews and classroom observations. The findings highlight the teachers’ conceptions of problem context and teaching approaches for each of these modes of knowing. All of the teachers used the paradigmatic mode in their teaching but with different depth and most engaged in some form of the narrative mode to create a classroom environment that was motivational for students to learn word problems. The paper also highlights characteristics of these two modes as they relate directly to word problems and discusses implications for instruction, learning and teacher development.     

单片机课程项目教学法的探索和实践

在现代教育中,建构主义学习理论与各门具体学科教学相结合产生的项目教学法,适用于学习各类实践性和操作性较强的知识和技能。单片机课程的教学偏重于操作和实践活动,项目教学法的选择显得水道渠成。在实施项目教学时,如何选取项目、如何完成项目、如何考核评价,对教师、学生提出哪些要求,值得我们探讨和实践。

Whose perception of principal instructional leadership? Principal-teacher perceptual (dis)agreement and its influence on teacher collaboration

This study examines teacher collaboration across three Asia-Pacific countries (Australia, Malaysia, and South Korea), focusing on the possibility that principal-teacher perceptual disagreement regarding principal instructional leadership performance may impede progress toward a school organizational condition conducive to collaborative teacher interactions. Data for this study were taken from the OECD Teaching and Learning International Survey 2008. Overall, the results from a series of hierarchical linear modelling analyses appear to give credence to the hypothesis that the degree to which a principal's self-evaluation of her/his instructional leadership diverges from teachers' perception of the leadership is likely to negatively influence teachers' engagement in collaborative activities and collegial interactions; in other words, teachers become more likely to establish collegial relationships with other teachers in a situation where there is little principal-teacher disagreement regarding principal leadership performance. The significant effect of principal-teacher perceptual disagreement found in this study was fairly consistent across all three countries examined despite the substantial differences among the countries in terms of socio-cultural background. This finding sheds light on the need for paying close analytic attention to principal-teacher perceptual agreement as it may constitute an important aspect of school capacity.     

Three Korean Heritage Language Teachers’ Identities,Their Identification of Their Students,and Their Instructional Practices

This study examined the instructional focuses and practices of three Korean heritage language (HL) teachers in community-based HL schools related not only to their constructed identities as HL teachers, but also to their students. Constant-comparative analyses of interviews and classroom observations across the three teacher cases showed that each teacher’s identity as an HL teacher was shaped by her earlier immigration experiences and through her relationships within and across a particular historical and social context. Moreover, the three HL teachers’ identities informed how they identified the imagined communities in which their students would eventually participate. The teachers’ different identifications and visions became significant in shaping their instructional focuses and practices related to teaching language and culture in a manner that would enable their students to learn and, therefore, gain access to their communities.
