For an introductory undergraduate biochemistry class, we developed an interactive, out of classroom, team project that would allow students to gain a better understanding of protein structure and function. This project involved the use of the molecular visualization program RasMol and computer simulated site-directed mutagenesis of selected amino acids of the enzyme, Uroporphyrinogen decarboxylase. Survey data from students after completion of the project indicated that they had developed a more complete understanding of protein three-dimensional structure leading to functionality. 相似文献

How can we use ICT to enhance the quality of pupil learning? The case study below deliberately embedded ICT within the context of an existing scheme of work to develop 11–12 year olds’ understanding of the skills and processes of historical investigation. It also mapped onto the existing teaching styles of the teachers involved, and reflected their orientation—beliefs and values. The role for the ICT was to present the pupils with a problem that would intrigue, excite and motivate them. Accordingly, we asked them to act in role as assistants to Harry and Hermione in investigating the strange death of Sam Woodhouse in 1822. The pupils carried out the investigation using a hyperlinked set of clues. They had undertaken two identical kinds of investigation earlier in the year. One was a murder mystery, the other the disappearance of the Princes in the Tower in 1483. For both these mysteries the clues were on cards. Comparisons of the results of the ICT mystery with those of the earlier two investigations suggest that the hyperlink version was equally effective in terms of developing understanding, with some clear advantages in developing pupils’ overall understanding of the problem and ability to make links between disparate clues and pieces of information. 相似文献

One hundred and three children attending Learning Assistance Centres due to reading difficulties and one hundred and three matched, average readers were administered a battery of auditory perceptual processing tasks. The battery was composed of auditory analysis and synthesis, auditory sequential memory, auditory discrimination, and phonemic segmentation tasks. A principal components analysis yielded four factors. These were determined to be advanced phonological awareness, sequential memory, discrimination, and simple phonological awareness. Discriminant analyses, using the factor scores, indicated that three of the four factors were able to discriminate between the able and disabled readers. Most notable among these was advanced phonological awareness. Auditory discrimination could not discriminate between the groups. The results suggest that there may not be one underlying phonological ability implicated in successful reading acquisition. Furthermore, it is clear that two levels of phonological awareness exist and that screening and diagnostic instruments should address both in order to have predictive validity. 相似文献

This paper challenges the view that academic professionalism resides in the professional 'autonomy' of the academic, the 'self-regulation' of academics as an occupational group, and the differential 'status' of academic workers. This still influential (though residual) notion of academic professionalism, it is argued, leads to institutional stasis. What is required is greater reflexivity by academics in respect of their underlying professional values. In particular the piece challenges the academic community (of which the author is a member) to re-think academic freedom – the bedrock of professional identity within that community – in terms of increased inclusivity: 'freedom for all' rather than 'freedom for academics' The paper touches on issues relating to practice and organisational structure, but focuses primarily on the need for academics to shift the moral bases of their claim to professionalism. In so doing, it also challenges the post-Dearing consensus that the debate on academic professionalism can be adequately conducted in terms of 'standards' and 'outcomes'. A prime purpose of the paper is to promote debate and discussion by setting a different kind of agenda (a moral agenda) and by couching that agenda within a different kind of discourse (one that invites and admits moral speculation). 相似文献

Early childhood programs have been in the forefront of implementing a multiracial curriculum. Early childhood educators need to extend these approaches to support and embrace multiracial and multiethnic children. These are children whose biological parents crossed traditional U.S. Census categories to have children. To meet the unique needs of these children and their families, early childhood educators need to engage in staff training, provide classroom materials, work closely with parents, and challenge the single race approach to multicultural education. 相似文献

The impact of national curriculum context on mathematics related beliefs of 12 beginning middle grades mathematics teachers was investigated after the teacher education program and first-year teaching through interviews and a combination of three belief frameworks. National curriculum requirements, lack of effective mentoring programs, and preservice tutoring experiences were detected as the major factors impacting beliefs. Participants simultaneously had teacher-centered and student-centered beliefs, causing inconsistency in beliefs and practices. While participants’ preservice and first-year experiences contrasted, they developed contextual beliefs to deal with the difficulties. Reflections on teacher education and beginning teacher support policies in national curriculum contexts were discussed. 相似文献

At the Universidad de Caldas, Manizales, Colombia, we used their new computer facilities to introduce chemistry graduate students
to biochemical database mining and quantum chemistry calculations using freeware. These hands-on workshops allowed the students
a strong introduction to easily accessible software and how to use this software to begin to explore computer modeling. Each
workshop was scheduled for 2 h and each included a tutorial exercise to familiarize the students with the main menus and features
of the software. In addition, accompanying lectures and practical laboratory sections were provided. Both courses were taught
in Spanish although the written instructions were in English. This was not a problem since these students have a comfort level
with reading English. Student feedback following these workshops was highly enthusiastic and positive. This international
collaborative will impact both the teaching and research goals for this cohort of graduate students. 相似文献

由于传统媒体的单向传输方式,远程教育在很长时间都没有很好地发挥其教学功能。现代教育技术的发展克服了原有的技术问题,在很大程度体现了双向交互功能,从文本会议形式到目前使用的博客,以及实时性视频会议系统,这些技术条件都为远程教育发展开辟了美好的前景。传统的观念只是将远程教育形式作为一种无奈的选择。这种认识并不是没有依据的。其主要观点是以往的学习者无法获得更多的技术,同时教学方法的采用也没有真正与技术自身的特质相匹配。即便是在今天,我们依然可以观察到在许多情况下,远程教育的教学方法与技术之间并没有达到真正意义上的和谐与统一。 相似文献
