How do college students solve proportion problems?

Problems which could be solved using proportional reasoning were administered nationwide by college faculty to their own science classes during a three year period. The reasoning of more than 8000 students covering three sections of the country was classified as concrete, transitional, or formal using Piagetian categories. Data from the West closely replicated that from the Midwest on similar metric conversion tasks. Student performance changed noticeably with a different problem format. The percentages of students using a ratio formula, ratio attempt, or intuitive methods of solution held approximately constant over time, task, and section of the country. The data shows the use of additive and conversion methods of solution depends upon the problem presentation.     

Trajectories of early childhood family instability and the development of externalizing behaviors from middle childhood to adolescence: A prospective study of at-risk families

This study examined associations between trajectories of family instability across early childhood and trajectories of externalizing behaviors from middle childhood to adolescence. Growth mixture models were fit to annual caregiver reports of instability from child ages 2–5 (N = 731; 49% girls, 50% White). A curve of factors model was fit to externalizing behaviors from child ages 7.5–14. Chronic, elevated instability across early childhood predicted elevated externalizing behaviors from middle childhood to adolescence. Data collection spanned from 2002 to 2017. Increasing or declining levels of instability predicted elevated externalizing behaviors in middle to late childhood, but not in adolescence. Caregiver depressive symptoms mediated the association between instability and the externalizing behavior intercept. Intervening on chronic instability may reduce child externalizing problems.     

Counselling with First Nations Women: Considerations of Oppression and Renewal

This article maps the historical background of First Nations women focusing on the residential school system, subsequent intergenerational trauma, and the effects of the Indian Act. Colonization has impacted the health and current roles and responsibilities of First Nations women. First Nations women's health needs to be viewed in a holistic framework that considers multiple levels of oppression, poverty, colonization, and life as a minority in a dominant culture. Social constructionism provides a new lens from which to question and re-conceptualize ways of working with First Nations women. Suggestions for the non-aboriginal counsellor in facilitating the healing process for First Nations women are offered.     

The relations of effortful control and impulsivity to children's resiliency and adjustment

The unique relations of effortful control and impulsivity to resiliency and adjustment were examined when children were 4.5 to 8 years old, and 2 years later. Parents and teachers reported on all constructs and children's attentional persistence was observed. In concurrent structural equation models, effortful control and impulsivity uniquely and directly predicted resiliency and externalizing problems and indirectly predicted internalizing problems (through resiliency). Teacher-reported anger moderated the relations of effortful control and impulsivity to externalizing problems. In the longitudinal model, all relations held at T2 except for the path from impulsivity to externalizing problems. Evidence of bidirectional effects also was obtained. The results indicate that effortful control and impulsivity are distinct constructs with some unique prediction of resiliency and adjustment.     

Race-Based Differential Prediction in Air Force Technical Training Programs

Bayesian Johnson-Neyman methodology was used to investigate differential prediction by race in United States Air Force technical training programs. Meaningful Johnson-Neyman regions of differences were found in eight of nine comparisons. In all nine training courses the regressions for blacks were flatter than for whites and the race-differentiated regression lines intersected within the range of predictor test scores. In six cases the cut-score for course qualification was within the Johnson-Neyman region, and in every case the bias was negative for blacks. It is noted that if the cut score had been set substantially higher the bias would have been positive for blacks in all cases. This analysis may explain why earlier studies that averaged bias across the predictor distribution yielded mixed results. It is hypothesized that the consistent results obtained here are a consequence of the lower predictability found in the black subpopulation.     

Contemporaneous and Longitudinal Prediction of Children's Social Functioning from Regulation and Emotionality

Relations of regulation and emotionality to social functioning were examined for 77 children followed from early to middle school age. Parents and teachers reported on children's social behavior, emotionality, and regulation, and children engaged in analogue peer conflict situations (i.e., with puppets). High-quality social functioning was predicted by high regulation and low levels of nonconstructive coping, nevatige emotionality, and general emotional intensity. Prediction often was obtained across reporters and time, although prediction was strongest within context (home versus school). Moreover, measures of regulation and emotionality frequently contributed unque variance to the prediction of social functioning. Contemporaneous correlations at age 8–10 were similar to those obtained at age 6–8, and prediction of later social functioning from emotionality and regulation at age 4–6 was similar at ages 6–8 and 8–10.     

Consistency and development of prosocial dispositions: a longitudinal study

The issue of whether there is consistency in prosocial dispositions was examined with a longitudinal data set extending from ages 4 to 5 years into early adulthood (N = 32). Spontaneous prosocial behaviors observed in the preschool classroom predicted actual prosocial behavior, other- and self-reported prosocial behavior, self-reported sympathy, and perspective taking in childhood to early adulthood. Prosocial behaviors that were not expected to reflect an other-orientation (i.e., low cost helping and compliant prosocial behavior) generally did not predict later prosocial behavior or sympathy. Sympathy appeared to partially mediate the relation of early spontaneous sharing to later prosocial dispositions. The results support the view that there are stable individual differences in prosocial responding that have their origins in early childhood.     

Does Part-Time Faculty's Self-Efficacy Predict Critical Dimensions of Online College Teaching?

Surveys have repeatedly depicted a dismal picture of part-time teaching in academia, including low pay, scant benefits, limited institutional support, and lack of job security. Thus, the main purpose of the present study was to delve deeper into part-time faculty's ability to sustain the demands of a tough work environment by examining the extent to which specific psychological characteristics predict key self-reported dimensions of teaching in such faculty. The sample selected comprised part-time online instructors, as they are a relatively new and growing entity in academia. Teaching dimensions upon which faculty rated themselves belonged to three categories of factors known to shape satisfaction of faculty in the online environment (i.e., instructor-related, student-related, and institution-related). They included current satisfaction with the teaching profession, preparation to teach subject matter, responsibility for students' academic success, beliefs in the impact of one's teaching on student learning, perceived institutional support, and desire to remain in the teaching profession (i.e., commitment). Psychological characteristics examined were self-efficacy and self-monitoring. In this study, each key dimension of teaching was found to be positively related to one or more self-efficacy measures, whereas no links with self-monitoring were uncovered. The findings involving self-efficacy confirm those of studies of full-time faculty in that beliefs of one's capability are a source of resilience and, as such, a staple of the teaching profession.     

Writing4practice in engineering courses: Implementation and assessment approaches

In this article, we analyze a two‐semester effort to integrate writing instruction into a multi‐disciplinary sophomore engineering design course in Northern Arizona University's College of Engineering and Technology. Specifically, we describe the programmatic implementation and assessment approach to evaluate whether student writing improved over the course of the semester. After discussing the reasons for taking a writing‐intensive approach to engineering, we analyze the results of a pre‐and post‐test administered over the span of an academic semester. Although the outcome of our assessment did not show significant improvement, we argue that writing instruction is important for increasing students’ overall learning skills. We conclude by pointing out several benefits and disadvantages of trying to assess writing improvement over two one‐semester periods.     

Student Apathy

In this article, we examine a new global studies program that departs from the traditional state-centric approach and uses a geocentric, or earth-centered, approach that emphasizes the roles of individuals, grassroots organizations, cultural groups, and international organizations in an attempt to help students conceptualize global events and their role in the world as interrelated and interdependent. We describe the process of program development, the program itself, and the challenges of program approval.
