运用“概念图”评价工科学生的跨学科知识集成——以“绿色工程”课程的跟踪研究为案例

概念图作为一项评测学生跨学科知识集成的工具开始受到工程教育学界的重视.概念图能够呈现学生对多学科概念和概念间的复杂联系的理解.本文通过对"绿色工程"设计课程的为期一年的跟踪研究证明了概念图方法尤其适合评测学生跨学科知识的学习性进步.本研究探讨了在跨学科评定环境中使用概念图出现的问题以及解决问题的建议.     

存在主义与马克思主义中的异化概念——现代社会思潮中的黑格尔式主题

本文聚焦于马克思主义和存在主义这两大现代社会思潮中由"异化"概念所统摄着的自我与社会这些黑格尔式的主题,批判性地考察了黑格尔哲学对"异化"概念的解释以及马克思主义和存在主义这两大现代社会思潮对其做出的不同回应,揭示了"异化"在这些哲学派别中作为一个评价性而非纯粹描述性概念的用法,强调了现代社会中的异化现象对于个人发展的积极意义.     

Team teaching with NES and NNES teachers

Language teachers are often categorised as either native or non native speakers,with some students, fee-paying parents,teachers and researchers subscribing to the idea that being a native English speaker (NES) is enough to make a teacher more valuable than a non-native English speaker(NNES).     

A computer simulation model of tennis racket/ball impacts

A forward dynamics computer simulation for replicating tennis racket/ball impacts is described consisting of two rigid segments coupled with two degrees of rotational freedom for the racket frame, nine equally spaced point masses connected by 24 visco-elastic springs for the string-bed and a point mass visco-elastic ball model. The first and second modal responses both in and perpendicular to the racket string-bed plane have been reproduced for two contrasting racket frames, each strung at a high and a low tension. Ball/string-bed normal impact simulations of real impacts at nine locations on each string-bed and six different initial ball velocities resulted in <3% RMS error in rebound velocity (over the 16–27 m/s range observed). The RMS difference between simulated and measured oblique impact rebound angles across nine impact locations was 1°. Thus, careful measurement of ball and racket characteristics to configure the model parameters enables researchers to accurately introduce ball impact at different locations and subsequent modal response of the tennis racket to rigid body simulations of tennis strokes without punitive computational cost.     

Towards evidence-based classification in wheelchair sports: impact of seating position on wheelchair acceleration

In most Paralympic wheelchair sports, active trunk range of movement is assessed by observing shoulder girdle excursion during active trunk movements and is a key determinant of an athlete's class. However, to date research evaluating the impact of reduced trunk range of movement on wheelchair sports performance has not been conducted. In the present study, 15 non-disabled male participants performed two 20-s sprints on a wheelchair ergometer in each of three seating positions. Positions were typical of those used to enhance sitting stability in wheelchair sport and each impacted available trunk range of movement differently: condition-90 (seated with thighs horizontal; unrestricted range of movement) condition-45 (seated with thighs in 45°), and condition-0 (seated with hips maximally flexed; minimum range of movement). In condition-90, the trunk only actively contributed to the first push; for the remainder of the sprint, the trunk was held almost isometrically at 48.2° to the horizontal (range 42.1-56.4°). Similar patterns were observed for both condition-45 and condition-0. Compared with condition-90, participants in condition-0 had reduced capacity to accelerate of statistical (P < 0.05) and practical significance. These findings are an important initial step towards evidence-based decision making in classification. Future research should evaluate the individual and collective impact of other factors that affect the trunk's contribution to wheelchair sports performance, including strapping, seating position, and impairments of trunk muscle power and coordination.     

Intentional Jealousy-Evoking Behavior in Romantic Relationships as a Function of Received Partner Affection and Love Styles

This study examined how (a) affection received from a partner and (b) love styles (i.e., eros, ludus, storge, pragma, mania, and agape) predicted the use of jealousy-evoking behaviors in romantic relationships. Participants were 197 undergraduate students currently involved in a committed romantic relationship, who completed a survey reporting on their partners' expressions of affection and their own perceived love styles and uses of jealousy evocation in their relationships. Results indicated that (a) after controlling for relationship length, the amount of affection received from a partner was inversely correlated with the use of jealousy-evoking behaviors, and (b) after controlling for relationship length and received affection, the ludus and mania love styles remained positive predictors of jealousy-evoking behavior. No other love styles were significant predictors.     

Understanding Relationships Among the Dark Triad Personality Profile and Romantic Partners’ Conflict Communication

This study examined the relationship of employee sex and information source with perceived job autonomy, satisfaction with immediate supervisor and perceived opportunities for career advancement. In addition to the main analysis, exploratory communication profiles were constructed for female and male respondents. Multiple regression revealed no pragmatically significant differences in the prediction models for men and women; however, elementary linkage analysis indicates that discrepancies may exist between female and male perceptions of career advancement opportunities in relation to other variables.     

Self-Deception in the Classroom: Educational manifestations of Sartre’s concept of bad faith

This article explores an important section of Jean-Paul Sartre’s famous early work, Being and Nothingness. In that section Sartre proposes that part of the human condition is to actively engage in a particular kind of self-deception he calls bad faith. Bad faith is recognized by the obvious inconsistency between the purported self-knowledge of an individual and ways of acting and being in the world that are demonstrably in defiance of that stated position. This article begins by exploring examples of this self-deception in education along with a short query into the role pain avoidance might play in the development of this particular skill. The article then goes on to offer a series of manifestations of bad faith that Sartre identified along with possible examples of how each example, perhaps ‘excuse’, of bad faith might appear in education.     

Understanding Seniors' Perceptions and Stereotypes of Aging

Research suggests there is a connection between stereotypes, beliefs, and behavior in older individuals. To explore this link of stereotypes affecting beliefs and beliefs affecting behavior, we interviewed young (age 60 to 75) seniors in an effort to further examine these relationships. Semistructured qualitative interviews were conducted with 20 seniors. Questions focused on the broad themes of aging stereotypes and attitudes towards active living. Responses from the participants indicated the variety of opinions and beliefs seniors hold about the aging process. Intriguing results emerged on the topic of role models. Participants often had someone in their lives who represented what it means to age successfully. Generally, this was an individual older than themselves, active, vigorous, and illustrative of the high quality of life that is possible into a very late age. In addition, these individuals provide a direct contrast to the most negative stereotypes of aging.
