Verbal Short-Term Memory Span in Speech-Disordered Children: Implications for Articulatory Coding in Short-Term Memory

One influential explanation of the development of verbal short-term memory in children argues that short-term memory capacity is a direct function of speech rate. This theory predicts that children with pathologically slow speech will show reduced verbal short-term memory capacity and will show less evidence of speech-base coding on verbal memory tasks. To test this prediction, verbal short-term memory span was assessed using a task that did not require a verbal response in 37 speech-disordered children and 37 age- and sex-matched controls (age range 4-15 years). The speech-disordered group had a significantly lower short-term memory capacity, a smaller word length effect, and reduced speech-motor activity during rehearsal periods. Covariance analyses revealed that these differences were not a function of general intellectual or motor speed differences between the groups, and that speech rate as a covariate abolished group differences in short-term memory. These results suggest that speech rate may be a causal determinant of verbal short-term memory capacity.     

The stability of kindergarten teachers’ effectiveness: A generalizability study comparing the Framework For Teaching and the Classroom Assessment Scoring System

To meet recent accountability mandates, school districts are implementing assessment frameworks to document teachers’ effectiveness. Observational assessments play a key role in this process, albeit without compelling evidence of their psychometric rigor. Using a sample of kindergarten teachers, we employed Generalizability theory to investigate (across teachers, raters, and lessons) the stability of scores obtained with two different observation measures: The CLASS K-3 and the FFT. We conducted a series of Decision studies to document (for both measures’ constituent domains) the number of lessons per teacher and raters per lesson that would justify the use of observation scores for high stakes decisions. Acceptable, stable scores for individual-level decisions about teachers may generally require more raters and lessons than is typically used in practice (1–2 raters and fewer than 3 lessons). The considerable variability of observation-based scores raises concerns about either measure’s appropriateness for making individual or group decisions about teachers’ effectiveness.     

Science as content,science as context: working in the science department

In this study we explored how the science department shaped the relationship between a science department head, Mr Greg, and a teacher, Ms Horton, as they grappled with their expectations of, and responsibilities for, teaching and leadership in the daily life in the department. We found that, from their life histories and their positions in the department, Mr Greg and Ms Horton have developed different values and visions that shape the ways they construct their work, particularly in relation to the place of subject matter, goals for students, teamwork, roles and responsibilities and accountability. Although both shared a commitment to their students and to their subject, Mr Greg saw his contribution in subject organizational terms and Ms Horton saw hers in personal student terms. Orderliness and stability were important to the department head whereas Ms Horton valued spontaneity and innovation. Collaboration was Mr Greg's method of achieving the business of the department; working alone allowed Ms Horton the freedom and flexibility she needed. Accountability for Mr Greg was framed in organizational terms; Ms Horton was more concerned with the learning that took place in her classroom. Our case study looks at the range and intensity of the forces shaping the work of teachers and the way they organize themselves at work. We argue that, if we wish to continue to improve teaching and learning, particularly in secondary schools, we need to know a great deal more about the forces that operate in subject departments.     

Achieving School Improvement through Challenging and Changing Teachers' Schema

The importance of changing teachers' beliefsand practices in school improvement efforts iswell accepted but little empirical work hasbeen reported on the micro-processes involved.In this paper, we use schema theory to examinehow the teachers in three schools changed theirbeliefs about the causes of low academicachievement from external factors, such as theparents' and children's deficits, to internalfactors, such as the contribution of their ownteaching practices. These change processes arecontrasted briefly with those in a fourthschool in which the teachers continued to blameexternal factors. The three conditionsidentified as critical for schema revisionincluded the salience of discrepant data, thepresence of an external agent to assist withthe interpretation of those data, and theavailability of information on alternativepractices.     

Student and faculty perceptions of plagiarism in health sciences education

Academic misconduct is a problem encountered by many academic programmes, including programmes in the health sciences. The primary purpose of the present study was to assess doctoral student and graduate faculty perceptions of academic misconduct, specifically plagiarism. We used a cross-sectional survey design, and separate surveys were developed for students and faculty. The student survey measured student perceptions of the prevalence of plagiarism among students in general and assessed the occurrence of each student’s plagiaristic behaviours. The faculty survey measured faculty perceptions of the prevalence of plagiarism among students in general and among students in their courses specifically. Two hundred and thirty-eight students and 92 faculty completed the surveys. Students were doctoral health sciences students enrolled in a campus-based, online or hybrid programme. Compared with the self-reported behaviour of students, faculty believed more students were involved with plagiarism. Self-rated knowledge about plagiarism was significantly higher among online students and faculty than among campus-based students and faculty (p<0.001). Both students and faculty believed the most common plagiaristic activity was citing and referencing a full-text source when only the abstract was read, but only a few students reported personally doing this. Additionally, more campus-based students than online students reported working closely with another classmate on an assignment when they were not authorised to do so (p<0.001). In the present study, surveyed students and faculty believed plagiarism was prevalent among the general student population; however, few students self-reported this behaviour.

The case for using exemplars to develop academic self-efficacy

Abstract

Academic self-efficacy is critical to academic success. Hence those working in higher education need to make deliberate and substantial attempts to foster academic competence, confidence, persistence and resilience in the students they teach, given they are essential components of academic self-efficacy. Addressing an identified gap in the exemplars literature, this article pays particular attention to how exemplars can be used in an embedded and sustained manner with the intent of fostering and supporting these components. Taking into account the three dimensions of self-efficacy – strength, magnitude and generality – and the various sources of information students draw upon to make judgements about their capabilities, four inter-dependent and inter-related practices and associated experiences are identified. We argue that collectively these practices and experiences can accentuate the positive effects and ameliorate the potential negative effects of exemplar use on student academic self-efficacy.
