Rats’ responses to molar and local schedule constraints

Three experiments explored responses to molar and local schedule constraints. Thirsty rats pressed a lever for access to a water spout. In Experiment 1, response totals were unaffected by two local schedule characteristics—the variability of the instrumental requirement and the variability of the magnitude of contingent reward. Experiment 2 manipulated the correlation between the instrumental requirement and the magnitude of reward. This correlation did not affect the behavioral price ratio (presses per lick) at a molar level. At a local level, the positive correlation created a lower mean lick price than did the negative correlation. The rats licked more, and licked less efficiently, under the positive correlation than under the negative correlation. Experiment 3 compared two ways of manipulating the molar presses/lick ratio: The instrumental (contingent) series varied the instrumental (contingent) requirement, but held the other requirement constant. As the ratio increased, total leverpresses increased, and total licks decreased linearly; the two series did not differ significantly. At higher lick prices, the rats licked more efficiently and made more extra licks at the spout as it closed. The results help delimit the applicability of molar models of the organism’s response to schedule constraints.     

Anxiety, depression, and peer relationships during adolescence: Results from the Portuguese national health behaviour in school-aged children survey

Use data from the Portuguese HBSC (Health Behaviour in School-Aged Children) survey, which was conducted by one of the authors who is the national representative of the European Study HBSC, a World Health Organisation collaborative study (Currie, Hurrelmann, Setterbulte, Smith, & Todd, 2000; Matos, Simões, Carvalhosa, Reis & Canha 2000), to examine correlates of depression and anxiety in a large, representative sample of adolescents. The study had four aims: (1) to examine the relationship between feelings of anxiety and depression; (2) to examine the association of positive peer relationships, and anxiety and depression in school-age adolescents; (3) to examine the relationship between health, peer relationships, depression and anxiety; and finally, (4) to assess age and gender differences with regard to the above issues. Measures were constructed of depression, anxiety, peer relationships, and health. Consistent with previous studies, anxiety and depression were found to be significantly correlated. A MANOVA revealed that females and adolescents in grades 8 and 10 were more likely to report high anxiety and/or depressive symptoms. High anxiety and depression in adolescence was associated with poor peer relationships and poorer health. Implications of these results and directions for further research are discussed.     

Creating the golden triangle of evidence-informed education technology with EDUCATE

EDUCATE is a London-based programme that supports the development of research-informed educational technology (EdTech), allowing entrepreneurs and start-ups to create their products and services, and simultaneously grow their companies in a more evidence-informed manner. The programme partners businesses with researchers who mentor, guide and support this research journey, a key aspect of which is the evaluation of the company’s EdTech product or service. However, conducting impact evaluations of technology in education is challenging, particularly for early stage technologies, as rapid cycles of innovation and change are part of their essence. Here, we present the pragmatic approach to evidence-informed education technology design and impact evaluation, as developed and adopted by the EDUCATE programme. The research process is shaped by the core principles of evidence-informed decision making detailed in the paper. The contributions of the paper are threefold. First, it defines and details an academia-industry-education collaboration model centred on a research training programme. Second, it presents emerging impact results of the programme. Third, it provides clear reflections on the challenges encountered during the implementation of the model in the EdTech ecosystem of London, which should be addressed if we are to move towards evidence-informed EdTech globally.     

Use of national parks for outdoor environmental education: An Australian case study

The need for environmental education through outdoor education experiences is becoming increasingly evident in outdoor education theory and practice. In Australia, this environmental focus is reflected in recent outdoor education curriculum documents, particularly in the Victorian Certificate of Education (VCE). For many outdoor education teachers who do not have expertise in environmental education, this curriculum development presents a challenge. Outdoor education teachers frequently use National Parks to help them address this challenge.

The study examined the educational objectives and roles of teachers and park staff involved in environmental education through outdoor education in National Parks in Victoria, Australia. This paper discusses findings related to the teachers' educational objectives and roles while those of the park staff are examined in a separate paper. The findings indicate that the teachers often lack the environmental knowledge and skills needed to teach some aspects of the curriculum thus making the role of the park ranger or education officer particularly significant in educating teachers as well as students. Issues are raised about the training of outdoor education teachers and of park rangers to meet the environmental education needs of outdoor education students. Questions are also raised about the appropriateness of using National Parks for outdoor education purposes.     

What verbal protocols reveal about the reading strategies of deaf students: a replication study

Deaf students' reading strategies were identified by investigating these students' self-reported thinking during reading. In an earlier study (Schirmer, 2003), 10 elementary-level students attending a state school for the deaf had constructed meaning, monitored comprehension and activated strategies to improve comprehension, and evaluated comprehension, but had not demonstrated each of the reading strategies within these three overarching activities, all observed in previous studies of hearing skilled readers. Also, the students used a considerably greater variety of reading strategies for constructing meaning than for the other two activities. The replication study used the same procedure. Six elementary-level students attending a site-based public school classroom for deaf students thought aloud after reading each page of a short story. Analysis of these verbal reports indicated the participants performed similarly to those in the first study, thus supporting the reliability of results regarding reading strategies of readers who are deaf.     

Enhancing Career Development Through the Career Success Club

The career development of students, demonstrated by students performing appropriate career developmental tasks, is important to institutions of higher education because career developed students are more likely to have career objectives, persist in their academic goals, gain career-related work experience, find employment in their chosen fields, and graduate. The purpose of this study was to determine if the career development of students by class level had been enhanced by participation in a career management plan specifically prepared for undergraduates. The intervention of a career management plan (i.e., the Career Success Club) was successful, especially for seniors and middles, in enhancing the career development of undergraduates. Career management plans may help students that are academically undecided to become more connected to their majors by focusing more on academic and career matters.     

Social anxiety,sex, surveillance,and the ‘safe’ teacher

Foucault's view of the body as a detailed text from which can be read a system of power is used to consider some aspects of contemporary teacher work. In particular, this paper considers the impact on primary school teachers of social anxiety about touching children. One effect has been an intensification of self‐surveillance by teachers, and increased experience of child‐touch and child‐proximity as ‘uncomfortable’. Paradoxically, teachers' need for visibility so they can be seen as innocent has the effect of constituting teachers as always and already guilty—as potential sexual abusers. This guilt is now enacted in the everyday common sense actions of ‘safe’ teachers. The argument is developed with reference to teacher union policy texts and interview data from teachers in a range of New Zealand primary schools.     

Positively Different: Art and Design in Special Education

This article explores issues of ‘difference’ in terms of identity for disabled pupils, including those with special educational needs in the context of art and design education. By focusing on body image and fashion, positive and negative views of those with a different identity, in relation to inclusion and visibility, in society and formal schooling are addressed. Inclusive values for those in a special school are identified and promoted with reference to a particular project in art and design.     

Effects of Poverty and Maternal Depression on Early Child Development

Researchers have renewed an interest in the harmful consequences of poverty on child development. This study builds on this work by focusing on one mechanism that links material hardship to child outcomes, namely the mediating effect of maternal depression. Using data from the National Maternal and Infant Health Survey, we found that maternal depression and poverty jeopardized the development of very young boys and girls, and to a certain extent, affluence buffered the deleterious consequences of depression. Results also showed that chronic maternal depression had severe implications for both boys and girls, whereas persistent poverty had a strong effect for the development of girls. The measures of poverty and maternal depression used in this study generally had a greater impact on measures of cognitive development than motor development.     

Nonshared environmental influences on individual differences in early behavioral development: a monozygotic twin differences study

The monozygotic (MZ) twin differences method was used to investigate nonshared environmental (NSE) influences independent of genetics. Four-year-old MZ twin pairs (N = 2,353) were assessed by their parents on 2 parenting measures (harsh parental discipline and negative parental feelings) and 4 behavioral measures (anxiety, prosocial behavior, hyperactivity, and conduct problems). Within-pair differences in parenting correlated significantly with MZ differences in behavior, with an average effect size of 3%. For the extreme 10% of the parenting-discordant and behavior-discordant distributions, the average NSE effect size was substantially greater (11%), suggesting a stronger NSE relationship for more discordant twins. NSE relationships were also stronger in higher risk environments, that is, families with lower socioeconomic status, greater family chaos, or greater maternal depression.
