Observational learning of discriminative avoidance in hooded rats

To determine the aspects of an observational situation facilitating subsequent acquisition of an observed task, two experimental groups of rats were exposed to a model’s performance of a two-way discriminative shuttlebox avoidance task with a tone as the discriminative stimulus. One experimental group (OND) observed the performance of a naive demonstrator; the other experimental group (OSD) observed a skilled demonstrator. A stimulus control group (SC) was exposed to the tone with no model present; a response control group (RC) observed demonstrator running with no tone present. A naive control group (NC) received no observational experience. All groups were subsequently tested on acquisition of the task. An analysis of variance on avoidance scores and Newman-Keuls tests for differences between means revealed that OND and OSD groups performed significantly more avoidances than the control groups. Exposure to the total tone-running sequence was found to be necessary for observational learning. The results were interpreted in terms of a sensory-sensory conditioning model.

     

Evaluating Environmental Education in the Context of a Junior High School State Studies Program

Abstract

This article discusses and offers solutions to three basic problems that environmentalists have encountered while teaching environmental ethics. The solutions include interdisciplinary study and research projects, teaching an intuitive understanding of the interrelatedness of the ecosystem, and a general, dynamic code of behavior for living an environmentally ethical lifestyle.     

Human Affection Exchange: VIII. Further Evidence of the Benefits of Expressed Affection

Affection exchange theory speaks to the benefits that affectionate communication elicits, not only when it is received but also when it is communicated to others. Previous research has provided evidence for the individual and relational benefits of having a high trait affection level, yet these benefits may partially be accounted for by the affectionate behavior one elicits from others by being affectionate in the first place. We addressed the validity of this alternative hypothesis in this project, first by re-analyzing data in which we compared correlations between trait affection level and various benefits with the same correlations after controlling for received affection. Next, in three studies involving a total sample of 1,144 people, we further investigated the benefits of expressed affection, both on its own and when received affection is covaried out. Results indicated that affection expressed to others is associated with numerous individual and relational benefits, including increased happiness and self esteem, decreased fear of intimacy and susceptibility to depression, and higher relationship satisfaction. Many of these effects are attenuated—and some are intensified—when affection received from others is held constant.     

The importance of workplace learning for trade unions: a study of the steel industry

This paper is concerned with the relationship between trade unions and learning in the workplace, particularly in relation to the enhancement of worker employability profiles. With the restructuring and modernising of the European steel industry as its context, this paper argues that the organisational and structural features of a sector have a profound influence on the way workplace learning is organised. Equally, trade union organisation and approaches also shape the learning agenda. In the steel industry, trade unions have failed to address the significance of workplace learning, partly because of the ways that they approach this topic. In the context of traditional sectors, with relatively vulnerable workforces, the weakened state of union bargaining positions means that they have limited capacity to address workforce employability or workplace participation. The outcome is that trade union involvement in skill formation and workplace learning is marginal.     

The motivations and outcomes of studying for part-time mature students in higher education

This paper examines the motivations and outcomes for mature students who study part-time in higher education (HE) in the UK. Although many students in HE are mature part-time learners, they have not been the specific focus of much research or policy interest. In-depth narrative interviews were carried out with 18 graduates who had studied part-time at a university college specialising in part-time provision. The sample was drawn from a quantitative survey of 1539 graduates concerning their motivations for studying and the benefits derived. Researchers could therefore choose respondents on the basis of previously reported outcomes of study and on other life course information, which was included in the survey. The paper reports a wide range of motivations and outcomes, which are regarded as forms of capital, and illustrates how studying part-time as a mature student can have a profound effect on people’s lives.     

A Mere Footnote? An American Dilemma and Supreme Court School Desegregation Jurisprudence

This article provides historical and legal context for recent U.S. Supreme Court school desegregation decisions. The Supreme Court's race-based and race-neutral arguments from Brown (1954) to Parents Involved (2007) are examined within their broader context. Policy implications and potential support for diversity goal arguments given the Obama administration's appointments of Sonia Sotomayor and Elana Kagan as the 111th and 112th Supreme Court Justices are considered in light of enduring issues and guiding ideals delineated over half a century ago in Gunnar Myrdal's landmark study of race in the United States, An American Dilemma.     

Parental views on the statutory assessment and educational planning for children with special educational needs

In Norway more than 95 per cent of the students in each annual school-leaving cohort from the lower secondary school continue on to upper secondary education. The result is that there is a wide range of abilities among the students, and so various forms of adapted teaching are necessary. Each year almost 10 per cent of the new entrants in upper secondary are classified as students with special needs. The main focus of this paper is on how different forms of adaptation influence the flow of special needs students through upper secondary education. Two groups are compared: one with students who in their first year are taught exclusively within ordinary classes, and one with students who receive adapted teaching in small groups outside ordinary classes. The analysis controls for the level of functional difficulties among the students. The study illuminates how the organization of the specially adapted teaching influences successes as well as failures among the students. A sample of special needs students from six Norwegian counties has been followed prospectively through upper secondary education. Results of this follow-up study are presented within a theoretical framework based on transitions in the life course.
