Validating a computerized scoring system for assessing writing and placing students in composition courses

How do scores from writing samples generated by computerized essay scorers compare to those generated by “untrained” human scorers and what combination of scores, if any, is more accurate at placing students in composition courses? This study endeavored to answer this two-part question by evaluating the correspondence between writing sample scores generated by the IntelliMetric™ automated scoring system and scores generated by University Preparation English faculty, as well as examining the predictive validity of both the automated and human scores. The results revealed significant correlations between the faculty scores and the IntelliMetric™ scores of the ACCUPLACER™ OnLine WritePlacer Plus test. Moreover, logistic regression models that utilized the IntelliMetric™ scores and average faculty scores were more accurate at placing students (77% overall correct placement rate) than were models incorporating only the average faculty score or the IntelliMetric™ scores.     

Power,prestige and pedagogic identity: a tale of two programs recontextualizing teacher standards

Worldwide there has been a range of initiatives in the area of standards for teachers as part of a discourse of professionalism. In Australia there are a plethora of standards: state and territory frameworks, generic and subject‐specific, systemic and cross‐systemic, for pre‐service, beginning and experienced teachers. Little has been written as to how teacher education programs are responding to the standards agenda. This paper positions standards as integral to the recontextualizing field (Bernstein, 2000 Bernstein B 2000 Pedagogy, symbolic control and identity: theory, research, critique (Lanham, Rowman & Littlefield)  [Google Scholar]) for teacher educators and their programs. Using Bernsteinian concepts of fields, identities and framing, we compare the responses of two physical education teacher education programs to their state's standards imperatives. The authors conclude that the academic orientation of the university, together with the framing of the standards, affect the degree of programmatic change it will undertake in response to the changes in teacher certification standards.

Legal Notes When May a College Regulate an Instructor's In-Class Speech? Recent Guidance from the Sixth Circuit

In a recent opinion, the Sixth Circuit Court of Appeals ruled that a community college instructor has a constitutional right to utilize the words nigger and bitch in the context of a classroom discussion in a course on interpersonal relations. This article discusses this case in the context of other court decisions concerning a college's right to regulate an instructor's classroom speech. Implications for personnel evaluation in the higher education setting are discussed.     

Summation and configuration between and within sensory modalities in classical conditioning of the rabbit

Three experiments examined “atomistic” and “configurai” processes in stimulus compounding using the rabbit’s conditioned nictitating membrane response. Two conditioned stimuli (CSs) were trained separately and then tested together in a compound. Animals trained with CSs from different modalities—namely, tone and light—showed summation in both acquisition and extinction. That is, the probability of a response to the compound could be predicted by the statistical sum of responding to the CSs. In contrast, animals trained with CSs from the auditory modality, tone and noise, showed a level of responding to the tone + noise compound that was the same as that of the CSs, well under the level predicted by the statistical sum of responding to the CSs. In conclusion, atomistic processes appear to predominate in cross-modal compounding. Configurai processes may occur during compounding within the auditory modality, but atomistic alternatives—namely, common elements and selective attention hypotheses—may be able to explain the results.

Developing a communal identity as beginning teachers of mathematics: Emergence of an online community of practice

The aim of this study is to investigate how a community of practice focused on becoming a teacher of secondary school mathematics emerged during a pre-service teacher education programme and was sustained after students graduated and began their first year of full-time teaching in schools. Bulletin board discussions of one pre-service cohort are analysed in terms of Wenger’s (1998) three defining features of a community of practice: mutual engagement of participants, negotiation of a joint enterprise, and development of a shared repertoire for creating meaning. Emergence of the online community was associated with our own role in facilitating professional dialogue, the voluntary and unstructured nature of participation, initial face-to-face interaction that created familiarity and trust, and the convenience of using email rather than logging on to a website. The study shows that the emergent design of the community contributed to its sustainability in allowing the pre-service and beginning teachers to define their own professional goals and values.

“课程思政”的内涵、问题及建设路径

"课程思政"是高校当前思政教育的一种新理念和新模式,它不是要取代以前通过思政课程进行思政教育的模式,而是要与思政课程同向同行,协同育人。"课程思政"不是一门课或几门课,也不是一项活动,而是一种全新的教育教学理念。高校"课程思政"建设中出现缺乏协同合作机制、专业课教师无法有效找到"融入点"、理工科"课程思政"更为复杂困难与"课程思政"形式化、同质化现象等问题。据此,需要从高校的顶层设计和整体规划、专业课教师尤其是理工科教师的"课程思政"教育能力提升、学生思政的自我提升几个方面着手进行"课程思政"建设。
