Easier Said Than Done: Rejoinder on Sijtsma and on Green and Yang

The main points of Sijtsma and Green and Yang in Educational Measurement: Issues and Practice (34, 4) are that reliability, internal consistency, and unidimensionality are distinct and that Cronbach's alpha may be problematic. Neither of these assertions are at odds with Davenport, Davison, Liou, and Love in the same issue. However, many authors in the testing community mention these terms not only together, but sometimes as if they are synonymous. Moreover, Cronbach's coefficient alpha is very popular as an index of reliability. Thus, articles discussing alpha are not only appropriate, but necessary. Our concerns are the same as formed the genesis of prior (2009) articles by these same authors, Sijtsma and Green and Yang. This rejoinder also makes comments about item parcels when tests are multidimensional and about factor analytic approaches to assessing reliability.     

Standardized test outcomes for students engaged in inquiry‐based science curricula in the context of urban reform

Considerable effort has been made over the past decade to address the needs of learners in large urban districts through scaleable reform initiatives. We examine the effects of a multifaceted scaling reform that focuses on supporting standards based science teaching in urban middle schools. The effort was one component of a systemic reform effort in the Detroit Public Schools, and was centered on highly specified and developed project‐based inquiry science units supported by aligned professional development and learning technologies. Two cohorts of 7th and 8th graders that participated in the project units are compared with the remainder of the district population, using results from the high‐stakes state standardized test in science. Both the initial and scaled up cohorts show increases in science content understanding and process skills over their peers, and significantly higher pass rates on the statewide test. The relative gains occur up to a year and a half after participation in the curriculum, and show little attenuation with in the second cohort when scaling occurred and the number of teachers involved increased. The effect of participation in units at different grade levels is independent and cumulative, with higher levels of participation associated with similarly higher achievement scores. Examination of results by gender reveals that the curriculum effort succeeds in reducing the gender gap in achievement experienced by urban African‐American boys. These findings demonstrate that standards‐based, inquiry science curriculum can lead to standardized achievement test gains in historically underserved urban students, when the curriculum is highly specified, developed, and aligned with professional development and administrative support. © 2008 Wiley Periodicals, Inc.

The pentagonal implicit theory of giftedness revisited: A cross‐validation in Hong Kong

This article addresses the cross‐cultural generalization of the pentagonal implicit theory of giftedness (Sternberg & Zhang, 1995) as well as differential expectations regarding excellence for girls versus boys. First, we used an instrument based on the pentagonal theory with a sample of in‐service and pre‐service teachers at the University of Hong Kong. Second, we administered a questionnaire designed to assess conceptions of “excellence,” one of the attributes for giftedness described in the pentagonal model, to a different sample of in‐service and pre‐service teachers at the same university. We found a good fit of the pentagonal model to the data collected, paralleling results obtained in the U.S. We also found, however, that in Hong Kong, however, unlike in the U.S., participants had higher expectations of excellence for boys than for girls. These outcomes have implications for identification, instruction, and programming for the gifted.     

Filling a curriculum gap in chemistry

In most science courses at secondary level, the teaching methods used are not tailored to present different approaches to meet the individual differences in pupils’ learning styles or motivation. Much in the detailed objectives, and blow‐by‐blow worksheet approach, will appeal to the conscientious pupil but may turn off the more creative and curious pupil.

Mini‐projects (problem solving at the bench) were used as a vehicle to motivate the curious pupils. Correlations of factors such as convergence/divergence, field‐dependence/field‐independence and motivational traits with ‘success’ in mini‐projects are set out in this paper. The evidence indicates that those who do best in practical problem solving of the mini‐project type are the curious, field‐independent and divergent pupils. However, all categories of pupils were stimulated to varying degrees by the projects.     

博物馆,生态博物馆,和反博物馆:解决遗产、社会和发展的思路

此探讨遗产与社会和发展间应当建立起新的关系。认为应当反思，从考虑遗产和其特性的方式上，尤其应当关注遗产地情况。在全球化的今天，化被认为是地区性的，——由地理边界划分。遗产的确定取决于它所处于的社会群体对价值的重要性的认识。因此，我们不能忘记民俗和传统的重要性是自发表现的。 地方遗产面对世界性强势化建立的不正当游戏规则的矛盾现实，所进行的运动是寻找有效的解决方法，世界遗产正在引起人们的重视。这样可能提供一种真正的生存，特别是对于小的社区，他们的社会经济结构和他们的价值观和行为动力相关联——确保可持续地发展他们的经济。地方社区才能对全部遗产的博物馆化作出反应。当我们考虑现在范例的时候，博物馆就可作为一种可持续发展的工具，以更加人性化的行动保护全部遗产。
