A practical test instrument was developed to assess students' attainment of skills associated with problem analysis and planning
experiments, collecting information, organising and interpreting information, and concluding. Students verbalised their thoughts
as they worked on the task and their performance was videotaped for analysis. Data collected from Year 7, 10 and 12 science
students illustrate the development of investigation skills and reveal important areas of student weakness.

W. Richard Bond's “Zero Tolerance: A New Enemy of Academic Freedom?,” Michael Kubara's “Academic Freedom,” and Fred Wilson's “In Defence of Speech Codes” included in the Symposium published in Interchange, Volume 27, #2, 1996, deal with the role and importance of academic freedom in Canadian universities and the pressures both within and without the academy for its attenuation. Although the Bond paper begins with the recent controversy in Ontario universities over the attempted introduction of a policy of zero tolerance of harassment and discrimination, it quickly moves to a summary of the traditional position regarding academic freedom in which that right is balanced by a corresponding responsibility. As insistent as Bond on the importance of academic freedom, Kubara and Wilson both approach the topic in a more argumentative fashion. Kubara and Wilson differ, however, in the kinds of arguments they propound. Kubara defends the traditional liberal conception of the university and attacks what he regards as the trendy feminist attack on academic freedom. Wilson recognizes that along with the rights bestowed by the acceptance of the principle of academic freedom is an obligation to engage in rational debate. The mechanism in Wilson's view for ensuring such debate is a well-crafted speech code in which professionally unacceptable speech acts are unambiguously defined. The fundamental difference between these two positions is that, whereas Kubara advocates an academic discourse that is as unfettered as is permissible within the law, Wilson proposes stricter limitations. I will discuss the Bond, Kubara, and Wilson papers in turn, commenting briefly on their positions. I will then present my own position on academic freedom and speech codes. 相似文献

This article initially outlines a procedure used to develop a written diagnostic instrument to identify grade-11 and -12 students' misconceptions and misunderstandings of the chemistry topic covalent bonding and structure. The content to be taught was carefully defined through a concept map and propositional statements. Following instruction, student understanding of the topic was identified from interviews, student-drawn concept maps, and free-response questions. These data were used to produce 15 two-tier multiple-choice items where the first tier examined content knowledge and the second examined understanding of that knowledge in six conceptual areas, namely, bond polarity, molecular shape, polarity of molecules, lattices, intermolecular forces, and the octet rule. The diagnostic instrument was administered to a total of 243 grade-11 and -12 chemistry students and has a Cronbach alpha reliability of 0.73. Item difficulties ranged from 0.13 to 0.60; discrimination values ranged from 0.32 to 0.65. Each item was analyzed to ascertain student understanding of and identify misconceptions related to the concepts and propositional statements underlying covalent bonding and structure. 相似文献

While constructivism has emerged as a major reform in science education from the last decade, wide-spread adoption of constructivist
practices in school laboratories and classrooms is yet to be achieved. If constructivist approaches are to be utilised more
widely, teachers will need to accept a more active and constructivist role in their own pedagogical learning. One experienced
junior science teacher was able to implement constructivist approaches in her classroom by using a personally constructed
metaphor to guide her practice.

This article investigates some of the administrative processes involved in setting up the School Organisation Committee (SOC) in one Shire County in England. Labour central government wants SOCs inter alia to make decisions on the planning and provision of school places 'more local and to speed up the process' that previously involved often lengthy periods of consideration of cases by the Secretary of State for Education. Local politicians' views on the SOC and the implications for local-central power relations are reported in this article. 相似文献

Increased opportunities for assessment and intervention, consultation, and program evaluation in early childhood education are suggested as roles that the school psychologist should develop to facilitate effective parent involvement in a child's education. A review of the literature on parent involvement in early childhood special education is provided. The current federal guidelines, rationale, definitions of parent involvement, and strategies for evaluating parent involvement are reviewed. 相似文献
