Discrimination of relative numerosity by pigeons

In three experiments, pigeons were trained to discriminate between uniform arrays of two elements that differed in color, form, or size. They were then tested with arrays that contained different proportions of the two elements on these dimensions. In all cases, orderly discrimination gradients reflected these proportions. The discrimination readily transferred to new arrays with similar stimuli, but with different total numbers of elements. In Experiment 4, the pigeons were taught to discriminate between two groups of categorical stimuli: pictures of birds and pictures of flowers. A test with different proportions of each again produced a gradient based on relative numerosity. Experiment 5 demonstrated transfer of stimulus control on the numerosity dimension when pigeons were trained with one set of instances from two categories, and then were tested with new instances from the same categories.     

Student Engineers and Engineer Identity: Campus Engineer Identities as Figured World

The research reported here contributes to understanding how student engineers on an engineering campus in the US mid-continent not only talked about the kinds of people recognized as engineers on campus, but also juxtaposes their talk about “campus engineer identities” with two students' ways of presenting themselves as engineers through engineering project teamwork to argue that campus engineer identities framed on-campus interpretations of actions, and ultimately that identity production was a complicated process through which campus engineer identities (cultural knowledge learned on campus) provided a lens of meaning through which to “recognize” (or not) performances of engineer selves as engineers. This research adds to conversations about identity in practice, especially identity production in science education, by suggesting the importance of cultural forms for belonging, especially at an obdurate site of science practice like the campus studied.     

Effect of Maternal Social Support on Attachment: Experimental Evidence

The present study used an experimental format to evaluate the influence of maternal social support on the development of attachment. 46 WIC primigravidas were randomly assigned to an experimental or control condition. Volunteer coaches, trained to provide maternal support and information, met with experimentals prenatally and during the first postpartum year. Experimentals and controls did not differ on demographics, ego level, verbal ability, affect, or perceived social support. At 14 months, experimental infants scored higher on an Attachment Ratings cluster from Waters and Deane's new Q-sort procedure. This cluster was more sensitive than a Criterion Sort measure in detecting the effect of the manipulation and as or more sensitive to maternal affect, perceived support, and the HOME. These findings provide experimental evidence regarding the importance of social support on infant attachment and support for an alternative approach for reducing data from the attachment Q-sort.     

‘It’s the parents’: re-presenting parents in school bullying research

Public discourse about school bullying is frequently underscored by debates about the relative roles and responsibilities of parents and schools in preventing bullying. Such debates are often characterised by a sense of recrimination, with blame apportioned according to perceived negligence. In this article, I provide a critique of ways in which parents have been represented in school bullying research, and consider how these representations inform public discourse about parents in relation to bullying. I argue that prevailing representations of parents in terms of responsibility and risk are a product of the dominance of psychological conceptualisations of bullying as individual pathological behaviour which stems from child development problems associated with poor parenting. As I show, this is but one of a number of ways in which bullying has been conceptualised in the research literature and provides a limited view of parents in relation to a complex social and cultural problem. I suggest that post-structural approaches to bullying research provide an important opportunity to broaden our understanding of how parents are positioned in the social and institutional systems of power in which bullying, and responses to it, takes place; and to move beyond current counter-productive discourses of responsibility and blame.     

The value of institutional research in the assessment of institutional effectiveness

A survey of 167 institutions engaged in the regional reaccreditation process between 1987 and 1992 revealed that the presence of institutional research activities was positively related to the institution carrying out a systematic assessment of institutional effectiveness. Institutional research activity was more predictive of assessment efforts than was the type of governance (public or private), the level of degree offered, or enrollment size. An alarmingly low proportion of institutions had begun to define outcomes at the time of the survey—a first step in the development of assessment procedures. Even fewer had identified ways of measuring outcomes. Budgets and staff expertise were felt to be adequate for current responsibilities but insufficient to assume responsibility for assessing institutional effectiveness. Institutional research activity is urgently needed in order to support the data collection efforts required by institutional assessment mandates. Whether these activities are conducted by institutional researchers or are dispersed across the campus, they provide the underpinnings for assessment.     

Third and fourth grade teacher’s classroom practices in writing: a national survey

A random sample of teachers in grades 3 and 4 (N = 157) from across the United States were surveyed about their use of evidence-based writing practices, preparation to teach writing, and beliefs about writing. Teachers’ beliefs included their efficacy to teach writing, their orientations to teach writing, their attitude about teaching writing, and their attitudes about their own writing. The teachers’ responses raised some concerns about the quality of writing instruction third- and fourth-grade students receive, as teachers reported spending only 15 min a day teaching writing and students spend only 25 min a day at school writing. While teachers indicated they used a variety of evidence based writing practices in their classroom, a majority of these were applied infrequently. Further, three out of every four teachers reported that their college teacher preparation programs provided no or minimal instruction on how to teach writing. They further rated their preparation to teach writing lower than their preparation to teach reading, math, science, or social studies. On a more positive note, a majority of teachers asked students to write multiple paragraph texts relatively frequently (4 times a month or more often) and complete at least one narrative, informative, and persuasive writing assignment monthly. Teachers were also generally positive about teaching writing, their efficacy to teach writing, and their beliefs about their own writing. Finally, efficacy to teach writing and philosophical orientations to teaching writing each made a unique contribution to predicting teachers’ use of evidence based practices, whereas teacher preparation did the same for reported time spent teaching writing and reported time students wrote at school and home.     

Student evaluations of teaching: the impact of faculty procedures on response rates

In the last 10–15 years, many institutions of higher education have switched from paper-and-pencil methods to online methods of administering student evaluations of teaching (SETs). One consequence has been a significant reduction in the response rates to such instruments. The current study was conducted to identify whether offering in-class time to students to complete online SETs would increase response rates. A quasi-experiment (nonequivalent group design) was conducted in which one group of tenured faculty instructed students to bring electronic devices with internet capabilities on a specified day and offered in-class time to students to complete online SETs. A communication protocol for faculty members’ use was developed and implemented. A comparison group of tenured faculty who did not offer in-class time for SET completion was identified and the difference-in-differences method was used to compare the previous year’s response rates for the same instructor teaching the same course across the two groups. Response rates were substantially higher when faculty provided in-class time to students to complete SETs. These results indicate that high response rates can be obtained for online SETs submitted by students in face-to-face classes if faculty communicate the importance of SETs in both their words and actions.     

How Diversity Approaches Affect Ethnic Minority and Majority Adolescents: Teacher–Student Relationship Trajectories and School Outcomes

This study aimed to relate school diversity approaches to continuity and change in teacher–student relationships, comparing Belgian-majority (N = 1,875, M_age = 14.56) and Turkish and Moroccan-minority adolescents (N = 1,445, M_age = 15.07). Latent-Growth-Mixture-Models of student-reported teacher support and rejection over 3 years revealed three trajectories per group: normative-positive (high support, low rejection) and decreasing-negative (moderate support, high-decreasing rejection) for both groups, increasing-negative (moderate support, low-increasing rejection) for minority, moderate-positive (moderate support, low rejection) for majority youth. Trajectories differed between age groups. Student and teacher perceptions of equality and multiculturalism afforded, and assimilationism threatened, normative-positive trajectories for minority youth. Diversity approaches had less impact on majority trajectories. Normative-positive trajectories were related to improved school outcomes; they were less likely, but more beneficial for minority than majority youth.
