Predictors of course outcomes: early indicators of delay in online classrooms

Studies have long shown that students who begin or submit their work later tend to have negative academic outcomes. The measures of procrastination used in those studies may not have provided information timely enough for instructor intervention. This article focuses on delay in the online environment among graduate students. We propose two new measures of delay that can be disclosed in a timely manner, enabling instructors to help students who are prone to late submissions to succeed. Date of class registration and date of initial class posting are negatively associated with final letter grades. Date of first class posting can serve to alert instructors to those with potential delay problems. The results for date of class registration are less clear.     

Journal Editorial Policies Regarding Statistical Significance Tests: Heat Is to Fire as p Is to Importance

The present paper responds to defenses of statistical significance testing offered by Levin and Robinson. First, some inaccurate perceptions of contemporary criticisms of statistical tests are noted. Second, areas of disagreement are explored. For example, it is noted that all nine empirical studies of reporting practices since 1994 show that encouraging (per the 1994 APA style manual) authors to report effect sizes has not worked; two reasons for this failure are explored. Finally, two important areas of agreement regarding needed improvements in contemporary practices are noted.     

Framing the Problem: effects of wording on children's statistical inferences

ABSTRACT A total of 96 children aged 11 to 12 years were given statistical inference problems (base‐rate and law of large numbers) designed to test the effects of wording on their answers. The wording of the problems was manipulated to make the information on base‐rates and on the law of large numbers either more salient or less salient. The latter condition was established by adding extraneous information to base‐rates, or, in the case of the law of large numbers, making the context unfamiliar or focusing choice on a particular person rather than on the group. A significant main effect of wording was found across all problems in favour of the salient condition. The results indicated that the children had a high level of statistical intuition and that they knew when to reason statistically and when not to.     

Expressed Readiness of Australian Schoolchildren to Act as Bystanders in Support of Children who are Being Bullied

Promoting interventive action on the part of student bystanders witnessing peer victimisation is currently seen as a promising way of reducing bullying in schools. A video depicting bullying in the presence of bystanders was viewed by late primary (n = 200) and early secondary school students (n = 200). Some 43% of the students indicated that they were likely to help the victim. Questionnaires were employed to assess student attitudes towards victims, beliefs about the expectations of parents, friends, and teachers, perceived self‐efficacy, and social desirability response set. Multiple regression analysis identified as significant predictors of expressed intention to intervene: attending primary school, having rarely or never bullied others, having (reportedly) previously intervened, positive attitude to victims, and believing that parents and friends (but not teachers) expected them to act to support victims. Implications for action to reduce bullying in schools are discussed.     

The abuse-related beliefs questionnaire for survivors of childhood sexual abuse

OBJECTIVE: To evaluate the psychometric properties of a new measure, the Abuse-Related Beliefs Questionnaire (ARBQ), designed to assess abuse-related beliefs among adult survivors of childhood sexual abuse (CSA). Study 1 examined the structure of the scale, and Study 2 evaluated its reliability and validity. METHOD: One hundred and seventy female CSA survivors recruited into a group psychotherapy intervention study were administered the ARBQ in Study 1. A subsample of 45 women completed the ARBQ again 12 months later. In Study 2, 70 women from a health maintenance organization who identified themselves as survivors of CSA completed the ARBQ along with the Trauma Symptom Checklist-40 (TSC-40) and the Symptom Checklist 90R (SCL-90-R). RESULTS: Three reliable ARBQ subscales emerged in Study 1: Guilt, Shame, and Resilience. Twelve-month test-retest reliability was high (r=.60-.64). The internal consistency of the subscales was further supported in Study 2, and validity was demonstrated by moderate to high correlations with the distress measures. CONCLUSIONS: The results indicate that the ARBQ has good psychometric characteristics, supporting the feasibility of its use in measuring abuse-related beliefs in research on survivors of CSA. A next step for validation of the ARBQ would be to evaluate its sensitivity in measuring changes in studies of interventions for treating CSA survivors.

Using Q-methodology to determine students' perceptions of interprofessional anatomy education

Interprofessional education (IPE) prepares healthcare students for collaboration in their future careers. The purpose of this study was to determine which aspects of the IPE Program in Anatomy at McMaster University contributed to the development of healthcare student's interprofessional skills. Q-methodology was used to identify the students' common viewpoints of the IPE experience. A total of 26/28 (93%) of students in the course from the medical, nursing, midwifery, physician assistant, occupational therapy, and physiotherapy programs participated in this study. Students were asked to sort a Q-sample of 43 statements about the IPE dissection course derived from previous qualitative studies of the program. Using the centroid factor extraction and varimax rotation, three salient factors (groups) emerged, namely: (1) Anatomy IPE Enthusiasts, (2) Practical IPE Advocates, and (3) Skeptical IPE Anatomists. The Anatomy IPE Enthusiasts believed that students from different disciplines brought unique anatomical knowledge and each group member guided others through difficult material. The Practical IPE Advocates expressed that they would be stronger advocates for interprofessional teams in the future because of the course. The Skeptical IPE Anatomists strongly disagreed that learning with students from different disciplines helped them gain an understanding of their roles in the context of other healthcare professionals and felt that there was little benefit from the IPE program compared to other non-interprofessional programs. These findings about student attitudes are critical to drive an evidence-based evolution of the IPE dissection course, since students' perceptions can have a profound influence on interprofessional collaboration in the workplace.
