Collaborative learning in engineering ethics 总被引:1,自引:0,他引:1
Joseph R. Herkert 《Science and engineering ethics》1997,3(4):447-462
This paper discusses collaborative learning and its use in an elective course on ethics in engineering. Collaborative learning
is a form of active learning in which students learn with and from one another in small groups. The benefits of collaborative
learning include improved student performance and enthusiasm for learning, development of communication skills, and greater
student appreciation of the importance of judgment and collaboration in solving real-world problems such as those encountered
in engineering ethics. Collaborative learning strategies employed in the course include informal small group discussions/problem
solving, role-playing exercises, and cooperative student group projects, including peer grading. Student response to these
techniques has been highly favorable. Realizing the benefits of collaborative learning is a challenge to both teachers, who
must give up some control in the classroom, and students, who must be willing to take greater responsibility for their learning.
An earlier version of this paper was presented by the author at a mini-conference, Practicing and Teaching Ethics in Engineering and Computing, held during the Sixth Annual Meeting of the Association for Practical and Professional Ethics, Washington, D.C., March 8–9,

This paper reviews the published empirical evidence concerning journal peer review consisting of 68 papers, all but three
published since 1975. Peer review improves quality, but its use to screen papers has met with limited success. Current procedures
to assure quality and fairness seem to discourage scientific advancement, especially important innovations, because findings
that conflict with current beliefs are often judged to have defects. Editors can use procedures to encourage the publication
of papers with innovative findings such as invited papers, early-acceptance procedures, author nominations of reviewers, structured
rating sheets, open peer review, results-blind review, and, in particular, electronic publication. Some journals are currently
using these procedures. The basic principle behind the proposals is to change the decision from whether to publish a paper
to how to publish it.

Knowledge of basic arithmetic facts aids in the acquisition and speed of performance of arithmetic operations. A peer mediated instructional procedure, Classwide Peer Tutoring (CWPT), has been shown to increase the rates and accuracy of students responses to academic tasks and to improve student performance on a variety of academic tasks. The present investigation evaluated the retention of 100 subtraction items by primary grade-age children with mild disabilities using CWPT for 10 weeks. Short- and long-term retention of items, and rate of correct responding were assessed. Results indicated that the students' average pretest score was 58.0% correct, and their average weekly posttest score was 87.12 correct, a 27% improvement in accuracy. Short- and longer-term retention measured on posttests was 88.7 % and 85.0% correct, respectively. Improvement in students rate of accurate responding to subtraction items practiced during CWPT was obtained. Student failure to learn particular items was not attributable to fewer opportunities to practice these items, less accurate practice, or item difficulty. Students reported positive evaluation of CWPT and perceived positive social and self esteem outcomes. Directions for future research focusing on retention and analysis of treatment failure are suggested. 相似文献

This study looked at how the social constellations in school classes relate to bullying problems. Using peer-evaluation questionnaires, the peer networks of children with different participant roles (such as victim, bully, assistant of bully, reinforcer of bully, defender of victim, outsider) were explored. The subjects were 459 sixth-grade-children (218 girls, 241 boys), aged 11 to 12 years, in Finland. The main findings were: 1) Children who tended to behave in either similar or complementary participant roles in situations of bullying formed networks with each other. The individual child's behavior in bullying situations was strongly connected to how the members of his/her network behaved in such situations. 2) Bullies, assistants, and reinforcers belonged to larger networks than did defenders, outsiders and victims. 3) Children outside the networks were most often victims. It was concluded that behavior in bullying situations can be said to be one feature around which the peer networks in school classes are organized. Thus prevention, as well as intervention strategies against bullying should focus not only on individual children, but also on the wider social context of the class. 相似文献

This research attempted to assess the relationship among the Pupil Evaluation Inventory (PEI), sociometric nominations, and sociometric ratings in terms of (1) a multitrait-multimethod analysis, (2) selection agreement indices of extreme individuals, and (3) stability over an 8-week period. Subjects were members of four second-grade classrooms at a regional school serving a diverse population of children. While stability estimates for measures were adequate and evidence for convergent validity was reasonably good, evidence for divergent validity was weaker. Selection agreement analyses yielded highly variable results, indicating that different samples of children tend to be selected by different instruments despite the similarity in dimensions being tapped. Methodological and theoretical implications of these findings are discussed.This work was based on the first author's M.S. thesis under the direction of the second author. 相似文献

在社会化过程中,同伴圈子不仅决定儿童青少年的交往范围和互动质量,而且影响其心理发展和社会适应。本研究从苏州市某初级中学选取768名初一学生进行了为期一年的追踪,采用社会认知地图、合作倾向评定量表和公共物品困境实验范式测查了同伴圈子、合作倾向、预期与合作行为,运用多层线性模型技术(Two-level HLM)探讨同伴圈子的合作水平对个体合作水平的影响。结果发现:(1)女生圈子数量最多而规模最小,男女混合圈子规模最大而数量最少;跨地域圈子数量最多且规模最大;(2)女生圈子最为稳定,男女混合圈子最不稳定;(3)在混合性别圈子中,个体的合作预期与行为更容易随着圈子合作预期水平的提高而增强;而在单性别圈子中,个体的合作预期与行为更容易随着圈子合作行为水平的提高而增强。结论:初中生同伴圈子在性别上具有同质性,女生圈子多且稳定;第一年单性别和混合性别圈子的合作倾向、预期和行为水平对第二年个体的合作水平产生了不同影响,即不同性别圈子对个体的影响模式存在差异。 相似文献

为探讨学校归属感对青少年手机依赖的影响及其作用机制,基于阶段环境匹配理论,本研究采用问卷法对山东省青岛市65所中学3355名高二年级学生进行调查。结果表明:(1)在控制了性别和上网时间后,学校归属感对青少年手机依赖具有显著的负向预测作用;(2)学习焦虑在学校归属感与青少年手机依赖之间起部分中介作用;(3)学校归属感对青少年手机依赖的直接作用、学习焦虑的中介作用均受到同伴关系的调节,且相对于同伴关系水平低的个体,学校归属感对手机依赖、学校归属感对学习焦虑以及学习焦虑对手机依赖的作用都在同伴关系水平高的个体中更强。本研究有利于揭示学校归属感是如何影响青少年手机依赖的,以及在何种条件下对青少年手机依赖的影响更强/更弱,对移动互联网时代预防青少年手机依赖有一定启示意义。 相似文献

累积压力假说与匹配-不匹配假说均可解释远端和近端逆境对个体抑郁的影响,但鲜有研究考察遗传基因在其中的调节作用。采用问卷法和DNA分型技术,对970名青少年进行间隔3年的追踪调查。分别以母亲消极教养、同伴侵害为远端和近端压力指标, FKBP5基因多位点累加得分为遗传指标,考察三者对青少年抑郁的交互作用及性别差异。结果发现,在男青少年中, E×E×G显著。当累加得分较高、同伴侵害水平较高时,母亲消极教养显著负向预测抑郁,符合匹配-不匹配假说;累加得分较低时, E×E不显著,但倾向于以累积压力假说的方式发挥作用。女青少年中, E×E×G不显著。研究结果提示,在男青少年中,累积压力假说与匹配-不匹配假说均可阐明抑郁的发生机制,分别适用于携带不同FKBP5基因多位点累加得分的个体。 相似文献
