Science in the Trenches: An Exploration of Four Pre-service Teachers' First Attempts at Teaching Science in the Classroom

This paper explores four students' attempts at teaching science in the real world classroom during their initial student teaching practicum, including their struggles and successes. When pre-service teachers enter their initial practicum experience they are confronted with differing teaching philosophies of their own, their university professors, and their school mentors (Sullivan, Mousley & Gervasioni, 2000; John, 2001; Fu and Shelton, 2002). Within this situation, preservice teachers struggle to find their own niche of teaching science and learn to reflect as both learner and teacher (Kelly, 2000). Our goal as science teacher educators is to help pre-service teachers have an easy transfer from personal university experiences to teaching science in the real classroom environment while maintaining the integrity of newly learned teaching strategies (Segall, 2001). This work adds to and helps guide science teacher educators in identifying difficulties pre-service teachers' experiences in the transition from methods courses to practice.     

Use of Culturally Diverse Books in Daycare

Culturally diverse books are written for children to promote acceptance of diversity; however, there is little research that has examined their use. The purpose of this study was to examine the culturally diverse book use of preschoolers in daycare. Research Findings. Thirty-five children (ages 44-65 months) and their teachers in two daycare classrooms participated. The children represented a variety of socioeconomic levels and raciaVcultura1 groups. Observations of book use were conducted during freeplay and naptime. In a multiple baseline time series experimental design, comparisons were made between the use of culturally diverse books and books depicting no cultural diversity (Euro-American books). It was determined that one category of culturally diverse books (Culturally Conscious) was not being used as frequently as others. The Culturally Conscious books depicted characters from one of three cultural groups—Black, Asian, and Latino. A simple intervention was implemented in which the teachers introduced some of the Culturally Conscious books at group times and this led to an increase in their use. Additional book use information was gained through parent questionnaires, teacher interviews, and teachers' anecdotal notes. Implications for Practice. In daycare centers similar to the ones used in this study, it is likely that children will use culturally diverse books when available. Teacher introductions of infrequently used culturally diverse books may be an efficient and effective practice for encouraging their use.     

Eliciting personal constructs and articulating goals

Summary A structured exercise that is based on PCP theory has been described and demonstrated to show how it can facilitate self-understanding and career development. The primary advantage of a PCP-based approach, when compared to approaches that use standardized inventories, is that a PCP approach encourages career explorers to use their own constructs. It is hypothesized that when people use goals that are articulated from their own constructs, they will understand their goals more fully and be more empowered to work towards those goals. A fuller understanding of their goals should allow them to find environments where these goals are more likely to be realized. Future investigations will continue to test these hypotheses.     

An engineering application for hypertext

This paper discusses the underlying framework for the protetype of a Hypertext-based tool for the preparation of on-line Design Brief Expansion (DBE) Documents as applied to a systematic design process. It describes the mapping of the DBE into Hypertext and shows how the electronic version of this process is not only more efficient, but also conveys more accessible information than a traditional paper version. It also explains how a natural language system (chunker) can be used to structure the information. The paper concludes with an assessment of how the prototype, implemented in C and HyperNeWS, will be used and a discussion of future improvements.     

Exercise, plasma catecholamine concentrations and decision-making performance of soccer players on a soccer-specific test.

The main aim of this study was to compare the decision-making performance of college soccer players on a soccer-specific, tachistoscopically presented test, at rest and while exercising at their adrenaline threshold and at their maximum power output. These were determined following an incremental test to exhaustion on a cycle ergometer. After the initial maximum power test, participants (n = 9) were allowed 10 habituation trials on the soccer decision-making test. Participants' decision-making performance was tested at rest, while cycling at a power output that had previously been determined to elicit their adrenaline threshold and while cycling at maximum power output. Accuracy and speed of decision were the dependent variables. A one-way repeated-measures analysis of variance showed no significant effect of exercise on accuracy, and showed speed of decision to be significantly affected by exercise. Tukey post-hoc tests showed that speed of decision at rest was significantly slower than in the other two conditions, which did not differ significantly from one another. Based on allocatable resources theories of arousal and performance, we conclude that the adrenaline threshold may be indicative of increases in the resources available to the individual. Furthermore, we considered that exercise at maximum power output may only induce a moderate rather than a high level of arousal.     

How Birth Doulas Help Clients Adapt to Changes in Circumstances,Clinical Care,and Client Preferences During Labor

This study examined how doulas adapt to challenges in client’s labors. There were 104 Canadian and 92 American doulas who responded to a survey distributed at a doula conference. We report results from open-ended questions in which doulas describe how they manage changes deviating from the mother’s birth plan and how they navigate differences of opinion between themselves and providers. Four themes emerged: giving nonjudgmental support, assisting informed decision making, acting as a facilitator, and issues with advocacy. Although 30% of doulas said that advocacy and information giving could result in conflict with providers, doulas reported working within their scope of practice and striving to be part of the team. Issues in doula responsibility and patient advocacy remain, and ongoing role clarification is needed.     

The auction market for artworks and their physical dimensions: Australia—1986 to 2009

Within a hedonic pricing model, the preferences of Australian art purchasers are investigated. Emphasis is placed on the impact of an artwork’s dimensions upon its auction price. A salient aspect of this is the first test of the ‘golden ratio’ hypothesis in a market situation. It is concluded that purchasers prefer paintings that deviate from the golden rule. The ‘orientation’ of works (portrait, landscape or square) as well as size also helps determine price. The impact of winning the Archibald portraiture prize (Australia’s foremost art prize) is found to have significant and positive impacts on winning artists’ prices. This suggests that purchasers are not fully informed. In addition, a previously unsuspected relationship between artwork dimensions and Archibald prize winners was found. As well as purchasers’ preferences, the artists’ choices of the dimensions of their artworks are considered.
