On line Forums as a `Rescue Net' in an Open Inquiry Process     

Michal Zion 《International Journal of Science and Mathematics Education》2008,6(2):351-375

The Biomind program is a new open inquiry program for Israeli biology high school students. The Biomind program is facilitated by diverse activities of asynchronous on-line forums for teachers and students. This research aims to analyse the discussions that occurred over a period of three years in these forums, in order to obtain a picture of the benefits that virtual discussions hold for the implementation of the open inquiry program. The results presented in this article indicate that students required assistance mainly with searching scientific information, finding experimental techniques and procedures, and phrasing inquiry questions. The three most frequent areas that were discussed in the teachers' forum were technical and procedural aspects of experimentation, bureaucracy and phenomenon identification. In addition, issues such as inferring and discussing, logical progression of the inquiry process, scientific writing, teacher-student interaction, reflective thinking, affective points of view, and forum administration were raised in the forum discourses. The forum discourses create a learning community that contributes to the implementation of the Biomind program, and pinpoint the aspects that should be taken into consideration in the future.  相似文献

Assessment of Students’ Understanding of Variation     

Jane M. Watson  Ben A. Kelly 《Teaching Statistics》2007,29(3):80-88

Several tasks used in research studies are presented with assessment rubrics and examples of the development of student understanding. The tasks focus on students’ appreciation of variation in several contexts and illustrate the need to discuss variation in the classroom and to ask students specifically about it during assessment.  相似文献

Data‐driven refinements of a genetics learning progression     

Moraima Castro‐Faix  Ravit Golan Duncan  Jinnie Choi 《科学教学研究杂志》2021,58(1):3-39

Learning progressions are theoretical models that describe learning of scientific ideas and practices over time. These hypothetical progressions need to be tested and refined in order to productively inform instruction and assessment. In this paper, we report our attempts to revise a learning progression in genetics. In particular, we focused on two constructs that embody core ideas in classical genetics and one molecular construct. The revisions are based on analysis of pre‐ and postinterview data obtained from sixty 11th grade students before and after they engaged in a 10‐week unit that addressed these concepts. We found that while many of the students held ideas that aligned with the progression, there were several distinct dimensions of student reasoning that were not captured and led to substantial revisions of the constructs including: (a) the splitting of the construct dealing with meiosis (E) into two subconstructs (E1‐physical passage of genetic information and E2 – the role of sex cells), (b) the addition of new levels to constructs dealing with the universal nature and organization of the genetic code (A) and construct (F). For Construct A, the lower levels were expanded to include ideas about the localization of DNA in cells and to include ideas about the composition of DNA that were not captured in the progression. Revisions to Construct F included the expansion of existing levels and the addition of modes of inheritance such as codominance and incomplete dominance. The research we present offers insights about a methodological approach that can be used to test and refine progressions, as well as insights about student learning in genetics as we further describe and expand the stepping‐stone ideas in the progression and discuss further the multidimensional nature of learning progressions.  相似文献   

Keeping plagiarism at bay—A salutary tale     

Ben R. Martin  other Editors of Research Policy 《Research Policy》2007,36(7):905-911

This editorial examines the question of whether plagiarism may be on the increase in the social sciences and, if so, what needs to be done to keep the problem in check. It was prompted by the discovery of an alert reader in June 2007 that a 1993 paper in Research Policy appeared to have plagiarised a 1980 article in the Journal of Business. The allegation was investigated, and it was agreed by the Editors that the 1993 paper constituted a clear and serious case of plagiarism. However, the author concerned has published over 100 articles and books. Already, two other publications have been judged by the editors of the journals concerned to have plagiarised previous publications. Two more are under investigation, but the great majority of the remainder still remain to be checked. The fact that academic misconduct on this scale has gone unchecked over such a prolonged period raises serious issues about the efficacy of the processes used to police the conduct of researchers. Furthermore, the unexpected discovery that a paper by the author under investigation appears itself to have been plagiarised poses a fundamental question as to whether plagiarism may be far more common than previously assumed. The editorial concludes that a measured degree of vigilance and a greater willingness to pursue any well-founded suspicions of research misconduct are required by editors, referees, publishers and the wider academic community if the scourge of plagiarism is to be kept at bay.  相似文献

UK university part-time higher education: a corpus-assisted discourse analysis of undergraduate prospectuses     

Adam Matthews  Ben Kotzee 《高等教育研究与发展》2020,39(6):1186-1201

ABSTRACT

In the UK, higher education (HE) policy discourse over the past 60 years has advocated flexible part-time HE for social mobility, personal development, economic advantage and leisure. However, part-time undergraduate HE in the UK is in steep decline. Against this backdrop, we were interested in how universities promote, or fail to promote, part-time study options today. We built a corpus of 90 UK undergraduate prospectuses for 2018 entry (5,673,799 words). Using a corpus-assisted discourse analysis approach, we found significant mismatch between policy discourse and marketing discourse regarding part-time study. In particular, we found that UK university marketing discourse positions full-time study as the dominant mode of study and writes of part-time study as ‘second-best’. This discourse mismatch is particularly marked when it comes to the elite Russell Group of universities. Viewing the absence of strong promotional discourse relating to part-time study alongside other factors such as increased tuition fees and the rise of global online education platforms adds a new perspective to the decline of flexible part-time undergraduate HE at campus-based universities in the UK.  相似文献
