The effectiveness of take-home science kits at the elementary level

A major reason for the lack of scientific and technological literacy in this country is the lack of emphasis on high-quality science education at the elementary school level. The National Science Board Commission on Precollege Education in Mathematics, Science, and Technology states in its report (1983) that formal study of science must be reinforced by a wide range of activities outside the school. Learning in the home appears to be an excellent way to enhance elementary school science programs. Students who study with their parents or whose parents are involved in school activities achieve more in school. This study describes and presents evaluation data for a program that encourages elementary school students and their parents to study science topics in a hands-on, inquiry fashion in their own homes. The analyses of the data indicate that the program is viewed very positively by both the students and their parents, that there are gender and grade-level differences in the students, and that the program seems to be more effective for girls, a group at risk for continuing in science.     

Cyberstalking, personal privacy, and moral responsibility

This essay examines some ethical aspects of stalkingincidents in cyberspace. Particular attention is focused on the Amy Boyer/Liam Youens case of cyberstalking, which has raised a number of controversial ethical questions. We limit our analysis to three issues involving this particular case. First, we suggest that the privacy of stalking victims is threatened because of the unrestricted access to on-linepersonal information, including on-line public records, currently available to stalkers. Second, we consider issues involving moral responsibility and legal liability for Internet service providers (ISPs) when stalking crimesoccur in their `space' on the Internet. Finally, we examine issues of moral responsibility for ordinary Internet users to determine whether they are obligated to inform persons whom they discover to be the targets of cyberstalkers.     

Do Belonging and Social Exclusion at School Affect Structural Brain Development During Adolescence?

Students’ sense of belonging presents an essential resource for academic and health outcomes, whereas social exclusion at school negatively impacts students’ well-being and academic performance. Aiming to understand how feelings of school-related belonging and exclusion shape the structural brain development, this study applied longitudinal questionnaire-based data and MRI data from 71 adolescent students (37 females, M_age at t1 = 15.0; t2 = 16.1 years). All were white participants from Germany. Voxel-based morphometry revealed only an association of social exclusion (and not of belonging) and gray matter volume in the left anterior insula: From t1 to t2, there was less gray matter decrease, the more social exclusion students perceived. School-related social exclusion and disturbed neurodevelopment are thus significantly associated.     

Book-Sharing for Parenting and Child Development in South Africa: A Randomized Controlled Trial

This study evaluated the impact of a parenting intervention on children’s cognitive and socioemotional development in a group of caregivers and their 21-to-28-month-old children in a low-income South African township. A randomized controlled trial compared an experimental group (n = 70) receiving training in dialogic book-sharing (8 weekly group sessions) with a wait-list control group (n = 70). They were assessed before the intervention, immediately following it, and at a six month follow-up. The intervention had positive effects on child language and attention, but not behavior problems, prosocial behavior, or theory of mind. Intervention caregivers were less verbally and psychologically harsh, showed more sensitivity and reciprocity and more complex cognitive talk. This program benefitted parenting and child development and holds promise for low-income contexts.     

Young Children''s Understanding of Different Types of Beliefs

The purpose of this investigation was to see whether children's understandings of different types of beliefs develop concurrently. Children of 3, 4, and 5 years of age were told or shown that child story characters held beliefs different from their own or from one another, not only concerning matters of physical fact ("false beliefs"), but also concerning morality, social convention, value, and ownership of property. In contrast to the older subjects, most 3-year-olds had difficulty in attributing to others deviant beliefs of all types, except perhaps ownership, sometimes even after having been told repeatedly what the other child believed. In addition, intercorrelations among different belief tasks were positive and substantial. It was suggested that an emerging representational conception of the mind is what enables older preschoolers to understand the possibility of belief differences of all these types.     

Differences between rates of responding emitted during simple and multiple schedules

Pigeons pecked keys for food reinforcers delivered by several variable-interval and multiple variable-interval schedules. The rates of responding emitted during the simple schedules were not systematically different from the rates emitted during the multiple schedules when the components of the multiple schedule were identical. The rates of responding emitted during the components were usually greater than the rates emitted during comparable simple schedules when the components were more favorable than the added components of the multiple schedules. Response rates during the components were not significantly lower than those during comparable simple schedules when the components were less favorable. The observation of higher rates of responding during the more favorable components conforms to a prediction of several additive theories (e.g., Rachlin, 1973) but violates a prediction of Herrnstein’s (1970) theory. However, the additive theories are brought into question by the fact that changing the location of the discriminative stimuli did not change the pattern of results.     

Negotiating school-university partnerships: Participants' voices in co-reform

Although many educators recognize the importance of voice, fostering voice in those who have traditionally been voiceless has been difficult. This article, like the program that it describes, tackles that challenge by having participants speak for themselves. Specifically, the participants speak about their involvement in the first year of an alternative teacher education project. In describing their involvement, the participants focus on their roles and relationships as well as the type of partnership and collaboration that emerged from this project.     

Identifying the Core in the Subject of Fine Art

This paper explores the basis and main characteristics of fine art as a subject discipline and looks at how these elements combine to create a distinctive and in many ways unique learning environment. Taking the premise that fine art as a subject discipline is concerned with encouraging the development of individual artistic practice and enabling the student to articulate and define the social and cultural context that they are working within, this paper considers how fine art students come to develop alternative ways of thinking, seeing and conceptualising. Referring to the Art and Design Subject Benchmark statements the paper argues that in a fine art education, a set pf principles, core characteristics, skills and abilities are combined to create a unique learning environment that gives its graduates a set of abilities that are particularly relevant to our complex society.
