The authors detail the development of an on‐line course, “Marketing Theory and Practice On‐line” (MTPO) as part of the charter‐mandated commitment of Monash University of Australia to deliver quality flexible education transnationally. The course, that is now offered to both on‐campus and distance education students, uses a full range of media and computer technologies, including the Internet, e‐mail, bulletin boards, on‐line library facilities, video animations, and hypertext. The guiding principles for the development of the course were that the methodology must enrich the learning experience; the communication shell must enrich a scholarly environment; and the subject development should encourage and facilitate new opportunities. The ultimate aim is to utilize MTPO as the basis for international collaboration and to use the collaboration in question to develop a stronger intellectual package with specialist marketing subjects at both the undergraduate and the postgraduate levels. 相似文献

This article compares the costs of four assessment formats: multiple choice, open ended, laboratory station, and full investigation. The amount of time spent preparing the devices, developing scoring consistency for the devices, and scoring the devices was tracked as the devices were developed. These times are presented by individual item and by complete device. Times are also compared as if 1,000 students completed each assessment. Finally, the times are converted into cost estimates by assuming a potential hourly wage. The data show that a multiple choice item costs the least, and that it is approximately 80 times as much for an open ended item, 300 times as much for a content station, and 500 times as much for a full investigation item. The very large discrepancies in costs are used as a basis to raise several policy issues related to the inclusion of alternative assessment formats in large scale science achievement testing. © 2000 John Wiley & Sons, Inc.

Recent research has shown that attitudinal ambivalence has importantimplications on political attitudes and behavior. The conceptholds one of the keys to understanding complicated and seeminglycontradictory opinions of the public. This article examinesambivalence in public opinion regarding democratic reform inHong Kong. Analysis of a representative survey (N = 600) showsthat common citizens indeed have a significant degree of ambivalencetoward the government's political reform bill proposed in 2005.Regarding consequences, objective ambivalence is shown to havegreater predictive power than subjective ambivalence. The formerrelates negatively to attitude extremity and weakens the attitude–behaviorlinkage. However, contrary to the usual finding in the literature,objective ambivalence also relates positively to protest participationintention. The theoretical and social implications of the findingsare discussed. Received for publication June 29, 2007. Accepted for publication October 8, 2008. 相似文献

This study examines the Noyce Program, which provides scholarships for STEM majors in return for teaching in high need schools.
The perceptions of 555 scholarship recipients were investigated using hierarchical cluster analysis, confirmatory factor analysis,
and Rasch analysis to determine how the scholarship influenced their commitments to teaching in high need schools. The analyses
indicated that recipients perceived the scholarship in two ways: it influenced their commitment to complete their certification
program and to teach in high need schools. Implications for teacher education programs include that recruitment strategies
should identify candidates who are committed to teaching in high need schools and programs should provide experiences to encourage
this commitment not just to become certified. 相似文献

In 1983, Heyneman and Loxley stated that in low income countries, school-level factors could account for a greater proportion of variance in student achievement as compared to student-level characteristics. The phenomenon has come to be known as the “HL effect” and signaled the important role of schools in developing countries. This study investigated the presence of the HL effect using a longitudinal sample of 1790 11.5-year-old students from 60 schools in a developing country, the Philippines. The main variables of interest were related to socioeconomic status and proxy measures of school quality. The correlates of achievement were explored using two-level multilevel modeling, while controlling for students’ prior ability. While findings did not support the presence of the HL effect in the sample, with schools accounting for only 3–5% of overall conditional variance, schools were found to be important in the production of higher achievement scores. 相似文献

In order to understand the process of identity formation in a community of practice, Wenger (2002) proposes a matrix framework whereby three qualities (connectedness, expansiveness and effectiveness) are matched against three modes of belonging (engagement, imagination and alignment). In this paper we use this framework to analyse the experiences of two teacher–mentors and interpret how their identities are formed during the process of mentoring student–teachers. Factors that contribute significantly to the development of their identity include the school culture, the ‘personalities’ of the other community members, and the influence of other relevant communities of practice. 相似文献

Whilst some philosophical progress has been made on the ethical evaluation of playing video games, the exact subject matter of this enquiry remains surprisingly opaque. ‘Virtual murder’, simulation, representation and more are found in a literature yet to settle into a tested and cohesive terminology. Querying the language of the virtual in particular, I suggest that it is at once inexplicit and laden with presuppositions potentially liable to hinder anyone aiming to construct general philosophical claims about an ethics of gameplay, for whom assumptions about the existence of ‘virtual’ counterparts to morally salient phenomena may prove untrustworthy. Ambiguously straddling the pictorial and the performative aspects of video gaming, the virtual leaves obscure the ways in which we become involved in gameplay, and particularly the natures of our intentions and attitudes whilst grappling with a game; furthermore, it remains unclear how we are to generalise across encounters with the virtual. I conclude by briefly noting one potential avenue of further enquiry into our modes of participation in games: into the differences which a moral examination of playfulness might make to ethical evaluation. 相似文献

Abstract Theories causing rotation of the body in diving were critically reviewed and a statement relating angular momentum to both the angle of lean and the angle of force was presented. Equations were developed by which the partition of energy between rotation and translation could be computed. 相似文献

Abstract Students (N = 104) enrolled in four low fitness, one middle fitness, and one high fitness class in basic physical education classes at the University of Connecticut participated in a 4-week program of isometric exercises done with an adjustable nylon belt which was stabilized against various body segments. Low, middle, and high fitness classes were compared in the amount of improvement made in the 5 items in which significant gains had been made. The MWF classes which did 30 min. of isometric exercises for 12 class meetings were compared to the TTh classes which met for 8 class meetings and which did the same isometric exercise program and in addition did stretching exercises and ran a mile. When all groups were treated together, mean gains of 1.1 in. in the vertical jump, .74 sec. in the agility run, .17 sec. in the 30-yd. dash, 151.9 lb. in the leg lift, and 57.0 lb. in the back lift were made. These were all significant at the 0.005 to the 0.0005 level. Small but significant gains were made in right and left grip, the Fait endurance hang, and the 380-yd. run. The low fitness classes made greater improvements in the leg lift, the vertical jump, and the agility run than did the middle or high fitness groups. The high fitness class made greater improvements in the back lift and in the 30-yd. dash than did the low or middle fitness classes. The classes which did only isometric exercises for a half-hour three times each week for 4½ weeks made greater mean gains in the vertical jump, the agility run, the 30-yd. dash and the back lift than did the classes which met for 60-min. periods twice each week for 4½ weeks and did stretching exercises and running in addition to the isometric exercises. However, the latter made greater gains in the leg lift. 相似文献
