Development of Student Understanding of Outcomes Involving Two or More Dice     

Jane M. Watson  Ben A. Kelly 《International Journal of Science and Mathematics Education》2009,7(1):25-54

Data from 154 interviews with students in grades 3 to 13 were analyzed to suggest a developmental progression of conceptual understanding associated with the sample space for two ordinary six-sided dice tossed simultaneously. The model was then considered in the light of responses to an extension task involving three six-sided dice with four sides painted black and two white. Forty-five of the interviews were longitudinal interviews of students 3 or 4 years after the original interviews, allowing for analysis of change in levels of understanding across time. This study suggests some of the intuitions and understandings that form the intermediate steps to a complete understanding of outcomes for two dice, as well as documenting the conceptual regression likely to occur when a more difficult task is encountered. Links to previous research, including well-known misconceptions, and educational implications of the model are among the discussion points.  相似文献   

Individualizing Student Instruction Precisely: Effects of Child × Instruction Interactions on First Graders' Literacy Development

Recent findings demonstrate that the most effective reading instruction may vary with children's language and literacy skills. These Child × Instruction interactions imply that individualizing instruction would be a potent strategy for improving students' literacy. A cluster-randomized control field trial, conducted in 10 high-moderate poverty schools, examined effects of individualizing literacy instruction. The instruction each first grader received ( n = 461 in 47 classrooms, mean age = 6.7 years) during fall, winter, and spring was recorded. Comparing intervention-recommended amounts of instruction with observed amounts revealed that intervention teachers individualized instruction more precisely than did comparison teachers. Importantly, the more precisely the children received recommended amounts of instruction, the stronger was their literacy skill growth. Results provide strong evidence of Child × Instruction interaction effects on literacy outcomes.  相似文献   

First year expectations and experiences: student and teacher perspectives   总被引：2，自引：0，他引：2

Transitioning from high-school to university can be difficult, and many university teachers feel students are often ill-prepared for the change. To investigate this 233 Humanities and Science students at the University of Adelaide were surveyed 6 months into their first year regarding experiences of teaching and learning at university. 189 students were also surveyed 18 months after commencement, to gain retrospective views of their transition year, as were lecturers and tutors of both groups. Results were compared to similar Orientation Week questionnaires that focused on expectations. Questions included reasons for selecting degrees, quality of teacher feedback and perceived impact of outside commitments. Even though student expectations, student experience, and teacher views differed, remarkable similarities emerged across the two degree programs (Science and Humanities). Our findings thus highlight a call for non-specialised transition programs to meet the needs of first year students and facilitate the transition from secondary to tertiary education.

Monitoring Rater Performance Over Time: A Framework for Detecting Differential Accuracy and Differential Scale Category Use     

Carol M. Myford  Edward W. Wolfe 《Journal of Educational Measurement》2009,46(4):371-389

In this study, we describe a framework for monitoring rater performance over time. We present several statistical indices to identify raters whose standards drift and explain how to use those indices operationally. To illustrate the use of the framework, we analyzed rating data from the 2002 Advanced Placement English Literature and Composition examination, employing a multifaceted Rasch approach to determine whether raters exhibited evidence of two types of differential rater functioning over time (i.e., changes in levels of accuracy or scale category use). Some raters showed statistically significant changes in their levels of accuracy as the scoring progressed, while other raters displayed evidence of differential scale category use over time.  相似文献   

Strange new world: applying a Bourdieuian lens to understanding early student experiences in higher education     

Jo Watson  Melanie Nind  Debra Humphris  Alan Borthwick 《British Journal of Sociology of Education》2009,30(6):665-681

Occupational therapy pre‐registration education stands at the intersection of the fields of health and social care and higher education. UK Government agendas in both fields have seen an increase in the number of students entering with non‐traditional academic backgrounds, a group noted to experience particular challenges in negotiating the transition to, and persisting and succeeding within, higher education. Drawing on data from an ongoing longitudinal case study, a Bourdieuian lens is applied to exploring the early educational experiences of a group of these students during their first year of study and highlights a number of key issues, including the high‐value status of linguistic capital and its relationship to understanding the rules governing practices within the learning environment, the processes via which students manage to adapt to or interestingly, to resist, the dominant culture of the field, and some of the barriers to finding a foothold and legitimate position within the new field.  相似文献   

Toward instituting a chaperone policy in outpatient pediatric clinics     

Kenneth W. Feldman  Carol Jenkins  Tyler Laney  Kristy Seidel   《Child abuse & neglect》2009,33(10):709-716

ObjectivesWe sought to evaluate child, parent and medical provider preferences for chaperones for outpatient encounters and to evaluate the acceptability and frequency of utilization following institution of a chaperone policy. Secondarily, we sought to understand what medical history and examinations teens consider “sensitive.”DesignWe conducted an observational study 1 month before and 1 month after institution of outpatient clinic chaperone policy. Post clinic questionnaires were used for patients ≥12 years old, parents, and clinicians. A research assistant observed chaperone use.SettingAdolescent Medicine, Urology, and Rehabilitation Clinics at a regional, tertiary-care pediatric hospital, in a major metropolitan area were studied.ParticipantsConvenience sample: 117 clinic patients during control period and 119 after policy implementation.Main outcome measuresPreferences for and satisfaction with chaperone use were documented.ResultsAlthough non-parent chaperones were usually declined (99.6%), offers were appreciated. Non-parent chaperone use increased modestly (5.3–18.1%).Most patients preferred not to have non-parent chaperones. This preference was greater among older patients (88%), than early teens (52%). After experiencing sensitive examinations, more young adolescent patients (89%) wished their parent had been present than older patients (38%). Patients’ opinions about what constitutes “sensitive” questions and examinations and chaperone preferences varied widely. Providers often did not recognize issues patients and parents considered sensitive questioning (21% agreement), but recognized sensitive physical examinations better (74% agreement). Providers felt chaperones had been a detriment to examination and exams would have gone better without one only 1% of the time.ConclusionsAlthough usually declined, offers of chaperones were appreciated and use of non-parent chaperones increased modestly. Offering chaperones for sensitive examinations may remind providers about appropriate, respectful patient encounters. Implications for children's hospitals’ patient safety and satisfaction, and institutional staff protection and costs are significant.Practice implicationsQuestions and examinations which patients consider sensitive vary widely. Asking patients for their preferences for examination chaperones may reassure them about the appropriateness of examinations, remind staff to conduct respectful examinations and protect providers from accusations of impropriety. Since most chaperone offers are declined, the cost of asking is likely to be minimal.  相似文献

What Does the Examination for Professional Practice in Psychology Step 2 (EPPP Step 2) Mean for College Counseling: The ASPPB Perspective     

Emil Rodolfa  Carol Webb  Jacqueline Horn 《Journal of College Student Psychotherapy》2017,31(1):4-11

We appreciate the opportunity to respond to the Editorial in this issue of the Journal of College Student Psychotherapy by editors Philip Rosenbaum and Ryan Weatherford, who express concerns about the new Examination for Professional Practice in Psychology Step 2 (EPPP Step 2). Our discussion describes the constellation of factors that influenced ASPPB’s decision to develop the EPPP Step 2 at this point in time. We also respond to the concerns expressed about the increasing costs of graduate training and the timing of the EPPP Step 2. Finally this commentary will highlight the difference between the training and licensing processes and will describe how the EPPP Step 2 will help licensing boards fulfill their mandate to protect a vulnerable public.  相似文献   

Determinants of recovery from a 161-km ultramarathon     

Martin D. Hoffman  Natalie Badowski  Joseph Chin  Kristin J. Stuempfle  Carol A. Parise 《Journal of sports sciences》2017,35(7):669-677

The primary study objective was to identify determinants of short-term recovery from a 161-km ultramarathon. Participants completed 400 m runs at maximum speed before the race and on days 3 and 5 post-race, provided a post-race blood sample for plasma creatine kinase (CK) concentration, and provided lower body muscle pain and soreness ratings (soreness, 10-point scale) and overall muscular fatigue scores (fatigue, 100-point scale) pre-race and for 7 days post-race. Among 72 race finishers, soreness and fatigue had statistically returned to pre-race levels by 5 days post-race; and 400 m times at days 3 and 5 remained 26% (P = 0.001) and 12% (P = 0.01) slower compared with pre-race, respectively. CK best modelled soreness, fatigue and per cent change in post-race 400 m time. Runners with the highest CKs had 1.5 points higher (P < 0.001) soreness and 11.2 points higher (P = 0.006) fatigue than runners with the lowest CKs. For the model of 400 m time, a significant interaction of time with CK (P < 0.001) indicates that higher CKs were linked with a slower rate of return to pre-race 400 m time. Since post-race CK was the main modifiable determinant of recovery following the ultramarathon, appropriate training appears to be the optimal approach to enhance ultramarathon recovery.  相似文献
