On the Stability of Performance Assessments

This study examined the stability of scores on two types of performance assessments, an observed hands-on investigation and a notebook surrogate. Twenty-nine sixth-grade students in a hands-on inquiry-based science curriculum completed three investigations on two occasions separated by 5 months. Results indicated that: (a) the generalizability across occasions for relative decisions was, on average, moderate for the observed investigations (.52) and the notebooks (.50); (b) the generalizability for absolute decisions was only slightly lower; (c) the major source of measurement error was the person by occasion (residual) interaction; and (d) the procedures students used to carry out the investigations tended to change from one occasion to the other.     

Measuring the Expertise of Paediatric Rehabilitation Therapists

This article describes the development of a classification system to measure the expertise levels of practicing paediatric rehabilitation therapists. Seventy‐five therapists from five disciplines (physical, occupational, speech‐language, behaviour, and recreational therapy) were involved, along with 170 peers, and 188 parents of children with disabilities. A cluster analysis of 10 indicators of expertise (derived from a battery of self‐completed, peer‐completed, and parent‐completed measures) indicated three levels of therapist expertise—novice, intermediate, and expert. Expertise level was related to various aspects of experience but not to therapy discipline. The classification system will be useful for the education and professional development of paediatric therapists, and for research on expertise in paediatric rehabilitation.     

A context-specific detrimental effect of UCS preexposure on place conditioning with morphine

The effect of morphine preexposure on place conditioning with morphine was investigated. In the first experiment, five injections of 10 mg/kg morphine were administered to rats prior to place conditioning or taste-aversion training with morphine. Although this number of preexposures retarded taste-aversion learning, there was no effect on place conditioning. In subsequent experiments we investigated the role of context blocking in UCS preexposure in place conditioning. In one experiment, preexposure to five morphine injections prior to place conditioning resulted in a reduced place preference, compared with preexposure and place conditioning in different contexts. However, the overall detrimental effect of morphine preexposure was questionable, because the rats that were preexposed were only marginally different from those that were not preexposed. In a final experiment we examined the effect of a context change from preexposure to place conditioning with 15 preexposures and demonstrated a detrimental effect of preexposure on place conditioning that was context specific. These results support a role of classical conditioning in place-preference conditioning with morphine.     

Using a Multilevel Assessment Scheme in Reforming Science Methods Courses

The development of new courses is strengthened by assessment and a response to the assessment. Two new science methods courses for elementary and secondary preservice teachers were developed, fostered by the Great Salt Lake Project. The preservice teachers designed and performed research projects that they then converted into inquiry-based teaching units. The professors applied a 3-layer assessment scheme to evaluate the courses and the preservice teachers based on changes in student attitudes, student-generated curricula, and internal course evaluations. Each type of assessment effectively informed the reform process, and strengths and weaknesses of the courses were revealed. Strengths of the courses included students learning to see science as a process and comprehending inquiry as a pedagogical approach. Weaknesses observed included a lack of understanding in three areas: the role of assessment, the need to address cultural issues, and the significance of scientific literacy.     

Developmentally Effective Experiences for Promoting Self-Authorship

ABSTRACT—Many national studies have identified types of experiences that are associated with enhancing college students' learning. This study contributes to the small but growing body of research on transformative educational experiences that assist and enable college students to develop ways of understanding and being in the world that help them adapt and respond to life's complexities and prepare for future civic, occupational, and family roles. The focus of this exploratory study is on those experiences that had a positive impact on college students' development toward self-authorship ( Baxter Magolda, 2001 ; Kegan, 1994 ). Using interview data from the Wabash National Study of Liberal Arts Education, we analyzed 300 selected experiences from 174 students. We found that students' approaches to interpreting and understanding their experiences was the major student characteristic that affected their learning (the effect of the experience). We then mapped these findings onto a sequenced developmental curriculum designed to promote self-authorship.     

Metacognitive analysis of pre-service teacher conception of Teaching Games for Understanding (TGfU) using blogs

Previous studies have sought to ascertain Teaching Games for Understanding (TGfU) conception in pre-service teachers. This exploratory study investigated the problems outlined in the literature surrounding the development of TGfU understanding among pre-service teachers (n = 44) of the curriculum instruction model. Blog postings were analysed over an eight-week period to identify the varying levels of student conception of TGfU using the Structure of Observed Learning Outcomes (SOLO) taxonomy in order to ascertain whether there are specific aspects of TGfU conception that prevent learning of deeper concepts. The study found that students move through at least two SOLO levels of metacognitive development. For pre-service teachers, TGfU represents a challenge to their pedagogical paradigm. This may limit their understanding of TGfU when they perceive that it is not antithetical to their existing paradigm but rather it represents a balanced approach to achieving the goals of skill-based instruction.     

Risk,identity and change: Becoming a mature student

This article looks at the stories mature students tell about the risks of higher education, in terms of its effects on identity and the implications for relationships with their families and former friends. Two sources of risk are highlighted in their stories; firstly, risks stemming from challenges to established gender roles in the family, which are mediated by the effects of social class; and secondly, risks that accompany the movement away from working class habitus which is an inevitable consequence of being in higher education. To be 'educated' is to stake a claim to a new identity which can be threatening both to one's own sense of self or to others. This may be experienced either as being seen by others as superior, or as feeling superior to others, but in both cases, there is an implicit challenge to former relationships. In their accounts, students describe how they try to manage relationships with families and former friends in order to minimise the disruption to their lives. Whatever strategy they adopt has consequences for their self-identity, which is experienced as fragmented and compartmentalised. In this process of becoming a different person, gender and class interact to produce specifically gendered and classed experiences of this painful transition.
