A Teacher Who Left His Mark

Abstract

Discussion of the nature of critical thinking and the ways in which it can be enhanced has increased in recent years among social work educators, and yet little is known about the impact of MSW education on the critical thinking of students. This paper examines the nature of critical thinking, presents an adult cognitive developmental model, the Reflective Judgment Model (King &; Kitchener, 1994), which holds promise for enlarging social work's understanding of critical thinking and examines approaches to teaching which enhance critical thinking. The Reflective Judgment Model focuses on the development of assumptions about knowledge and the process of knowing as development occurs through adulthood. Specific implications for creating classroom and field learning environments are detailed, including characteristics of effective teachers and of effective assignments.

全宗号管理新探

全宗号是档案馆(室)给定每个全宗的代码,目前至少有3种档案案卷缺失,这造成了档号不全,识别不清、统计不实、管理不严的严重后果。全宗号缺失的基本原因是学理性解释误导、社会档案意识滞后、法规执行不到位。解决全宗号缺失的主要方法是建立馆外全宗号体系,包括家庭档案全宗号、集体档案全宗号和特殊单位档案全宗号。

Learning by analogy: Discriminating between potential analogs

The ability to successfully discriminate between multiple potentially relevant source analogs when solving new problems is crucial to proficiency in a mathematics domain. Experimental findings in two different mathematical contexts demonstrate that providing cues to support comparative reasoning during an initial instructional analogy, relative to teaching the same analogs and solution strategies without such cues, led to increased ability to discriminate between relevant analogs at a later test. Specifically, providing comparative gestures and visibly aligned source and target problems during initial learning led to higher rates of positive extension of learning to new contexts, and lower rates of susceptibility to misleading contextual features, both immediately and after a week delay.

A study of the effect of HyperCard and pen-paper performance assessment methods on expert-novice chemistry problem solving

This study investigated HyperCard as a tool for assessment in science education and determined whether or not a HyperCard assessment instrument could differentiate between expert and novice student performance (balancing stoichiometric equations) in science education. Five chemical equations were presented by traditional pen-paper and by a HyperCard (Hyperequation) program. Thirty honors (expert) and 30 regular (novice) chemistry students were randomly divided into HyperCard and traditional pen-paper groups of 15 students each. Scoring was based on five dependent variables: performance scores, number of attempts, rate of attempts, time on task, and correctness. Correlation results indicated that students with high performance scores correctly balanced more equations, required fewer attempts to balance equations, and required less time per attempt than did students with low performance scores. MANOVA results showed that performance scores and correctness scores for both experts and novice were significantly higher on HyperCard compared to pen-paper assessment; the novice scores on HyperCard nearly equaled the expert pen-paper assessment scores. Significant interactions were found for time on task and for correctness. The results suggest that HyperCard can be a suitable tool for assessment in science education and that such an instrument can differentiate between expert and novice student performance.
