科学教学中的"探究"释义

根据教学论,科学教学中的“探究”可有三层含义:作为教学目标,指学生应掌握的科学探究技能,要理解的科学探究特性;作为教学原则,指激发学生积极探究未知、主动建构意义的基本教学要求;作为教学方法,指学生在教师指导下所采用的类似科学探究过程的学习方式或程序。     

From learning to development: a sociocultural approach to instruction

Theories of human development and learning provide an essential framework in which to understand the mechanisms involved in the process of formal instruction as a specific form of teaching and learning in the school setting. The sociocultural theory of development, founded on the works of Lev Vygotsky, espouses the view that social interaction among two or more people is the greatest motivating force in human development. Communication, via the use of language, provides one of the most effective means of social interaction. By collaborating toward a common cultural goal, people co‐construct new knowledge by building on each participant's contribution. Based on the main tenets of sociocultural theory, the following eight interrelated principles for instruction are presented, namely, that it should be: mediated; discursive; collaborative; responsive; contextualized; activity‐oriented; developmental; and integrated.

The nature of advanced reasoning and science instruction

Although the development of reasoning is recognized as an important goal of science instruction, its nature remains somewhat of a mystery. This article discusses two key questions: Does formal thought constitute a structured whole? And what role does propositional logic play in advanced reasoning? Aspects of a model of advanced reasoning are presented in which hypothesis generation and testing are viewed as central processes in intellectual development. It is argued that a number of important advanced reasoning schemata are linked by these processes and should be made a part of science instruction designed to improve students' reasoning abilities. Concerning students' development and use of formal reasoning, Linn (1982) calls for research into practical issues such as the roles of task-specific knowledge and individual differences in performance, roles not emphasized by Piaget in his theory and research. From a science teacher's point of view, this is good advice. Accordingly, this article will expand upon some of the issues raised by Linn in a discussion of the nature of advanced reasoning which attempts to reconcile the apparent contradiction between students' differential use of advanced reasoning schemata in varying contexts with the notion of a general stage of formal thought. Two key questions will be discussed: Does formal thought constitute a structured whole? And what role does propositional logic play in advanced reasoning? The underlying assumption of the present discussion is that, among other things, science instruction should concern itself with the improvement of students' reasoning abilities (cf. Arons, 1976; Arons & Karplus, 1976; Bady, 1979; Bauman, 1976; Educational Policies Commission, 1966; Herron, 1978; Karplus, 1979; Kohlberg & Mayer, 1972; Moshman & Thompson, 1981; Lawson, 1979; Levine & linn, 1977; Pallrand, 1977; Renner & Lawson, 1973; Sayre & Ball, 1975; Schneider & Renner, 1980; Wollman, 1978). The questions are of interest because to date they lack clear answers, yet clear answers are necessary if we hope to design effective instruction in reasoning.     

The Online Academy formative evaluation approach to evaluating online instruction

The Online Academy (HO29K73002) was funded by the Office of Special Education Programs (OSEP) to develop online instructional modules in the content areas of reading, positive behavior support, and technology across the curriculum. Targeted to preservice teacher education programs in institutions of higher education (IHE), to date, the modules have been adopted for implementation by 162 institutions. A requirement of the funding agency was that the content of the modules be research based. A total of 75 lessons in 22 online modules and an authoring software tool were developed. Each module is approximately equivalent to a one-semester credit course. This paper describes the formative evaluation processes that were employed in creating the instructional design, design and production processes, content development, usability and navigational features of the modules, and the national implementation process.
