Neighborhood disadvantage: pathways of effects for young children

The present study used Canadian National Longitudinal data to examine a model of the mechanisms through which the effects of neighborhood socioeconomic conditions impact young children's verbal and behavioral outcomes (N= 3,528; M age = 5.05 years, SD= 0.86). Integrating elements of social disorganization theory and family stress models, and results from structural equation models suggest that both neighborhood and family mechanisms played an important role in the transmission of neighborhood socioeconomic effects. Neighborhood disadvantage manifested its effect via lower neighborhood cohesion, which was associated with maternal depression and family dysfunction. These processes were, in turn, related to less consistent, less stimulating, and more punitive parenting behaviors, and ultimately, poorer child outcomes.     

‘Am I doing it right?’ Conceptualising the practice of supervising master’s dissertation students

ABSTRACT

An action research project involving 25 master’s supervisors, from health and education disciplines, sought to enhance their understanding of dissertation supervision. Recognising that they were sometimes slightly unsure about their role, they sought to identify issues that contributed to this circumstance, and to develop supervisor preparation materials to support future colleagues. During interviews and collaborative workshops, colleagues shared their experiences and reflected with one another on the nature of supervision. Through this process, they constructed a model that conceptualises how they practice. The core element is an ongoing assessment of a student’s readiness, motivation and individual situation. In response to this assessment, supervisors balance three functions: Facilitating, Nurturing and Maintaining Standards. Facilitating encourages student growth through challenge or stimulation. Nurturing involves the provision of support and reassurance within a safe space in which this growth can occur. Maintaining standards ensures that academic and professional rigour are preserved.     

Prosocial and Aggressive Behavior: A Longitudinal Study

Developmental theorists have made strong claims about the fundamental prosocial or aggressive nature of the human infant. However, only rarely have prosocial behavior and aggression been studied together in the same sample. We charted the parallel development of both behaviors from infancy to childhood in a British community sample, using a two-construct, multimethod longitudinal design. Data were drawn from the Cardiff Child Development Study (CCDS), a prospective longitudinal study of a volunteer sample of parents and their firstborn children. A sample of 332 mothers was recruited from National Health Service (NHS) prenatal clinics and general practice clinics in Wales, UK, between Fall of 2005 and Summer of 2007. Potential participants represented the full range of sociodemographic classifications of neighborhoods. Participating families were divided about equally between middle- and working-class families, were somewhat more likely to have sons than daughters, and the majority (90%) were in a stable partnership. In response to standard categories recommended for use in Wales at the time, the majority (93%) of mothers reported themselves as Welsh, Scottish, English, or Irish; most others named a European or South Asian nationality. Of the 332 families agreeing to participate, 321 mothers (M_age = 28 years) and 285 partners (M_age = 31 years) were interviewed during the pregnancy and 321 of the families contributed data at least once after the child's birth. After an initial home visit at 6 months, data collection occurred in four additional waves of testing when children's mean ages were approximately 1, 1.5, 2.5, and 7 years. Data collection alternated between family homes and Cardiff University. Of those families seen after the child's birth, 89% were assessed at the final wave of testing. Data collection ended in 2015. Methods included direct observation, experimental tasks, and collection of reports from mothers, fathers, other relatives or family friends, and classroom teachers. Interactions with a familiar peer were observed at 1.5 years. Interactions with unfamiliar peers took place during experimental birthday parties at 1 and 2.5 years. At 7 years, parents were interviewed, parents and teachers completed questionnaires, and the children engaged in cognitive and social decision-making tasks. Based on reports from parents and other informants who knew the children well, individual differences in both prosocial behavior and aggression were evident in children. Both types of behavior showed stability across the second and third years. The association between prosocial behavior and aggression changed over time: at 1.5 years, they were not significantly related (the association approached zero), but they became negatively correlated by 3 years. Different patterns were seen when children played with familiar versus unfamiliar peers. At 1.5 years, when children were observed at home with a familiar peer, prosocial behavior and aggression were unrelated, thus showing a pattern of results like that seen in the analysis of informants' reports. However, a different pattern emerged during the experimental birthday parties with unfamiliar peers: prosocial behavior and aggression were positively correlated at both 1 and 2.5 years, contributing to a general sociability factor at both ages. Gender differences in prosocial behavior were evident in informants' reports and were also evident at the 1-year (though not the 2.5-year) birthday parties. In contrast, gender differences in both prosocial behavior and aggression were evident by 7 years, both in children's aggressive decision-making and in their parents' and teachers' reports of children's aggressive behavior at home and school. By age 7, children's aggressive decision-making and behavior were inversely associated with their verbal skills, working memory, and emotional understanding. Some children had developed aggressive behavioral problems and callous-unemotional traits. A few (12%) met diagnostic criteria for conduct disorder or oppositional-defiant disorders, which had been predicted by early angry aggressiveness and lack of empathy for other people. Taken together, the findings revealed a gradual disaggregation of two ways in which children interact with other people. Individual differences in both prosocial behavior and aggression revealed continuity over time, with gender differences emerging first in prosocial behavior, then in aggression. Restrictions in the participant sample and the catchment area (e.g., all were first-time parents; all were drawn from a single region in the United Kingdom) mean that it is not possible to generalize findings broadly. It will be important to expand the study of prosocial behavior and aggression in other family and environmental contexts in future work. Learning more about early appearing individual differences in children's approaches to the social world may be useful for both educational and clinical practice.     

Girls,boys and conceptual physics: An evaluation of a senior secondary physics course

This paper reports an evaluation of the physics course at Dickson College (ACT) looking at students' high school experience, their expectations before beginning and their impressions and feelings during the course. In general, students seem to have a fairly negative approach to physics, enrolling for a variety of often vague utilitarian reasons but with little expectation of enjoyment or interest. These opinions were most prevalent in girls who tend to find the content difficult and the course as a whole uninteresting. There is also a significant difference between girls and boys in their response to different types of assessment items. In an attempt to enhance the level of interest and enjoyment in students we have been phasing in a more ‘conceptual’ approach to the teaching of physics.

Unique Patterns of Cognitive Outcomes for Undergraduate Students at Southern Baptist Colleges: A Comparative Analysis

The purpose of this study was to examine the levels of growth in cognitive outcomes among students attending Southern Baptist universities, as compared to their peers at other Council of Christian Colleges & Universities (CCCU), Catholic, and nonsectarian institutions, and to identify the college experiences that contribute to cognitive development. Using data from the College Senior Survey, inferential analyses revealed that students enrolled at Southern Baptist colleges and universities had significantly higher levels of academic self-concept and perceived cognitive skills than students enrolled at other types of Christian institutions. In addition, regression analyses showed that the Baptist sample yielded some unique patterns as to which college experiences contributed to cognitive outcome development among students.     

The Effects of Instruction on Students' Generation of Self-Questions When Reading Multiple Documents

The purpose of this research was to examine the effects of instruction on students' generation of questions when reading multiple documents. Participants were 151 undergraduate students who were randomly assigned to one of two conditions: a treatment condition that received question generation instruction and a control condition that did not receive question generation instruction. All participants read four primary-source documents and were asked to generate up to 10 questions based on those documents. Results indicate that students generated significantly fewer higher-order integration questions without instructional support. These results are replicated with an alternative document set to demonstrate that the effects found were not due to the specific historical topic.     

Beyond Average: Contemporary statistical techniques for analysing student evaluations of teaching

Student evaluations of teaching (SETs) have been used to evaluate higher education teaching performance for decades. Reporting SET results often involves the extraction of an average for some set of course metrics, which facilitates the comparison of teaching teams across different organisational units. Here, we draw attention to ongoing problems with the naive application of this approach. Firstly, a specific average value may arise from data that demonstrates very different patterns of student satisfaction. Furthermore, the use of distance measures (e.g. an average) for ordinal data can be contested, and finally, issues of multiplicity increasingly plague approaches using hypothesis testing. It is time to advance the methodology of the field. We demonstrate how multinomial distributions and hierarchical Bayesian methods can be used to contextualise the SET scores of a course to different organisational units and student cohorts, and then show how this approach can be used to extract sensible information about how a distribution is changing.     

Is starting with the feet out of the water faster in backstroke swimming?

This study aimed to determine if starting with the feet above the water (FAW) in male backstroke swimming resulted in faster start times (15-m time) than when the feet were underwater (FUW). It was hypothesised that setting higher on the wall would generate increased horizontal force and velocity, resulting in quicker starts. Twelve high-level male backstrokers performed three trials of the FAW and FUW techniques. A biomechanical swimming testing system comprising one force plate (1,000 Hz), four lateral-view (100 Hz), and five overhead (50 Hz) video cameras captured the swimmers' performance. Data for each participant's fastest trial for each technique were collated, grouped, and statistically analysed. Analysis included Wilcoxon, Spearman Rho correlation, and regression analysis. Wilcoxon results revealed a significantly faster start time for the FAW technique (p < 0.01). Peak horizontal force was significantly smaller for FAW (p = 0.02), while take-off horizontal velocity was significantly greater (p = 0.01). Regression analysis indicated take-off horizontal velocity to be a good predictor of start time for both techniques, and the horizontal displacement of the centre of mass for the FAW start.     

A Genetically Optimized Predictive System for Success in General Chemistry Using a Diagnostic Algebra Test

In higher education, many high-enrollment introductory courses have evolved into “gatekeeper” courses due to their high failure rates. These courses prevent many students from attaining their educational goals and often become graduation roadblocks. At the authors’ home institution, general chemistry has become a gatekeeper course in which approximately 25% of students do not pass. This failure rate in chemistry is common, and often higher, at many other institutions of higher education, and mathematical deficiencies are perceived to be a large contributing factor. This paper details the development of a highly accurate predictive system that identifies students at the beginning of the semester who are “at-risk” for earning a grade of C- or below in chemistry. The predictive accuracy of this system is maximized by using a genetically optimized neural network to analyze the results of a diagnostic algebra test designed for a specific population. Once at-risk students have been identified, they can be helped to improve their chances of success using techniques such as concurrent support courses, online tutorials, “just-in-time” instructional aides, study skills, motivational interviewing, and/or peer mentoring.     

Development and Testing of a Curriculum to Improve Decision-Making Skills in Middle and High School Students

Adolescence is a key developmental period for developing and strengthening brain circuits that underlie effective decision-making skills, which profoundly impact lifelong health and academic, professional, and economic achievement. But decision-making skills are learned rather than inherent. School presents an ideal environment for the direct instruction and frequent practice of decision-making skills, however, finding time in the school day is a challenge for contemporary educators. We have developed a learning curriculum that involves active student participation to strengthen decision-making skills that is sufficiently flexible and adaptable to be utilized in a wide variety of content-specific classwork. Using this curriculum, students show evidence of improved decision-making skills, including increased consideration of the number of factors that are relevant to their decision, the resources needed to make a particular decision, and both the short-term and long-term consequences of decisions.
