COURSE PLANNING AND TESTING DECISIONS IN CRITERION‐REFERENCED SITUATIONS

Norm‐referenced measurement tools — such as reliability, validity, and item analysis — are commonly used to reach and verify conclusions about criteria. Similar tools for criterion‐referenced testing situations are scant. This study examined faculty planning and testing decisions and applied formulas to arrive at numerical indices that serve as analytical tools for use with criterion‐referenced tests. The research documents the effects of applying the concept of platform unity, which has its roots in curriculum alignment theory. Alignment of curriculum occurs if the planned, the delivered, and the tested curricula are congruent. Specifically, platform unity aligns planned, domain‐referenced content with appropriate test types. Mathematical formulas were created to determine numerically if planned and tested content were congruent. In addition, four other constructs were examined. They included effectiveness and efficiency of test‐item type selection and overtesting and undertesting of course content. A chi‐square goodness‐of‐fit test was used to compare faculty planning and testing decisions. Data indicated significant differences (p < .01) between content plans and the test types used to test content. On the basis of the analysis, it was determined that faculty do not plan and test content congruently across three levels of cognitive content. Also, faculty tended to overtest content; they were effective in their selection of test types, but not efficient.     

Culturally Responsive Pedagogy and Online Learning: Implications for the Globalized Community College

Implicit in the open-door mission of the community college is the mandate that every learning experience should offer full equity and inclusion for all learners, including those of diverse cultural backgrounds. This mission is paramount, given the cultural diversity represented among learners served by the globalized community college. This paper presents a cross-section of research, practice, and discourse focused on expanding our knowledge and understanding of the diverse learning needs of community college learners. The relevance of the literature to the planning, design, and implementation of distance-learning is discussed. In the end, the authors offer distance-learning instructional strategies that may accommodate the unique needs of Hispanic/Latino learners. Implications for community college educators are discussed.     

Two-Level Dynamic Structural Equation Models with Small Samples

Advances in data collection have made intensive longitudinal data easier to collect, unlocking potential for methodological innovations to model such data. Dynamic structural equation modeling (DSEM) is one such methodology but recent studies have suggested that its small N performance is poor. This is problematic because small N data are omnipresent in empirical applications due to logistical and financial concerns associated with gathering many measurements on many people. In this paper, we discuss how previous studies considering small samples have focused on Bayesian methods with diffuse priors. The small sample literature has shown that diffuse priors may cause problems because they become unintentionally informative. Instead, we outline how researchers can create weakly informative admissible-range-restricted priors, even in the absence of previous studies. A simulation study shows that metrics like relative bias and non-null detection rates with these admissible-range-restricted priors improve small N properties of DSEM compared to diffuse priors.     

Growth Mixture Models Outperform Simpler Clustering Algorithms When Detecting Longitudinal Heterogeneity,Even With Small Sample Sizes

The expansion in the number of people entering higher education has resulted in a substantial increase in the proportion of students enrolling in nontraditional modes, such as part-time study. This study examined the question of whether part-time study curtails the development of the types of intellectual capabilities needed for a knowledge-based economy, because the students would have markedly less exposure to a stimulating campus environment than their full-time counterparts. Graduates from discrete full- and part-time programs from 1 university in Hong Kong completed a survey seeking perceptions of the nurturing of a range of capabilities, together with measures of teacher-student relationships and type of teaching experienced. Two hypotheses were tested by structural equation modeling: (a) the same mechanism for capability development operated for full- and part-time modes and (b) the principal element of the mechanism was the nature of teaching and the quality of teacher-student interaction. Hypothesis 1 was supported because configural invariance between hypothesized models for capability development between the 2 modes was found. Hypothesis 2 was also supported because the models showed that the principal influence on capability development came from teaching for understanding, through promoting active learning experiences and the degree and quality of teacher-student interaction.     

Confidence Intervals for a Semiparametric Approach to Modeling Nonlinear Relations among Latent Variables

Compared to parametric models, nonparametric and semiparametric approaches to modeling nonlinearity between latent variables have the advantage of recovering global relationships of unknown functional form. Bauer (2005) Bauer, D. J. 2005. A semiparametric approach to modeling nonlinear relations among latent variables. Structural Equation Modeling, 12: 513–535. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar] proposed an indirect application of finite mixtures of structural equation models where latent components are estimated in the service of more flexibly recovering characteristics of the latent aggregate regression function. This article develops and evaluates delta method and parametric bootstrap approaches for obtaining approximate confidence intervals for Bauer's semiparametric approach to modeling latent nonlinear functions. Coverage rates of these approximate point-wise confidence intervals or nonsimultaneous confidence bands are evaluated by Monte Carlo and recommendations for their use are suggested.     

On Going (Way) Beyond One’s Data: A Proposal to Restrict Recommendations for Practice in Primary Educational Research Journals

To counteract what we see as a growing research-reporting concern, we propose the following editorial-policy change regarding the content of primary research articles in educational research journals: Contributors should restrict their discussion and conclusions to their data and not offer recommendations for educational practice nor speculate about the educational policy implications of their research. We believe that this change will be beneficial for maintaining a separation between evidence and opinion concerning the legitimate warrants of empirical research. We suggest viable accompaniments and alternatives to authors offering practical recommendations and policy speculations in primary-research journal articles. Among these is to rely on all sources of evidence, including systematic research syntheses based on the aggregated contribution of multiple research studies from different sources, with recommendations for practice tailored to specific situations so that both their validity and utility will be increased. It is hoped that our proposed policy change will initiate a conversation among researchers, editors, reviewers, and educational-policy experts with respect to the scope and purpose of primary research journal articles.     

Teaching abjection: A response to the war on terror

In this paper, the author discusses pedagogy and strategy within the current climate set by the “War on Terror”. Deploying Lacanian psychoanalysis in a critique of standardized knowledge, the author develops a theory of “abject pedagogy” that seeks to subvert the current “regimes of truth” while providing educators with a viable pedagogy during this “state of emergency”.     

让MOOCs更有意义:在谎言、悖论和可能性的迷宫中沉思

大规模开放网络课程(MOOCs)是一种以开放访问和大规模参与为目的的在线课程。MOOCs作为一种新的教育技术,包括cMOOCs和xMOOCs两种,前者以联通主义理论为基础,强调知识创新与生成;后者以行为主义理论为基础,关注知识重复。两者在教学理念上差异很大,用同一术语表述很容易使人混淆。同以往各种形式的信息技术一样,MOOCs在本质上是一系列操作符号的工具,同时也是基于互联网的低成本教育材料分发和共享的工具,因此在对待MOOCs变革传统高等教育这一问题上应该理性。目前媒体、商业集团和高校机构对xMOOCs的关注处于一种狂热状态,缺乏系统而理性的学术研究,主要体现出四个谎言和悖论:一是学校品牌是教学质量的象征,而实际上它们的声誉是由其研究赢得的,并非教学质量,xMOOCs的低完成率为传统高校所不齿;二是多数xMOOCs机构对成功通过课程考试的学生只提供证书,不生成学分,对比传统学校教育,意味着对学生学业的认证取决于招生而不是课程学习;三是xMOOCs是一种新的教学法并支持个性化学习,而实际上他们采用的是一种过时的行为主义教学法;四是xMOOCs一方面期望和推崇"让知识成为人类共同财产"的理想,却又一方面在积极探索能够盈利的商业模式。MOOCs在炒作背后应该回归理性的发展轨迹,其对传统教育的真正变革应该是将xMOOCs置于全世界公众的视野中,迫使这些机构重视教学和教学法,并将教学作为其核心使命。     

The effects of mid-flight whole-body and trunk rotation on landing mechanics: implications for anterior cruciate ligament injuries

ABSTRACT

The purpose was to quantify the effects of mid-flight whole-body and trunk rotation on knee mechanics in a double-leg landing. Eighteen male and 20 female participants completed a jump-landing-jump task in five conditions: no rotation, testing leg ipsilateral or contralateral (WBRC) to the whole-body rotation direction, and testing leg ipsilateral (TRI) or contralateral to the trunk rotation direction. The WBRC and TRI conditions demonstrated decreased knee flexion and increased knee abduction angles at initial contact (2.6 > Cohen’s dz > 0.3) and increased peak vertical ground reaction forces and knee adduction moments during the 100 ms after landing (1.7 > Cohen’s dz > 0.3). The TRI condition also showed the greatest knee internal rotation angles at initial contact and peak knee abduction and internal rotation angles and peak knee extension moments during the 100 ms after landing (2.0 > Cohen’s dz > 0.5). Whole-body rotation increased contralateral knee loading because of its primary role in decelerating medial-lateral velocities. Trunk rotation resulted in the greatest knee loading for the ipsilateral knee due to weight shifting and mechanical coupling between the trunk and lower extremities. These findings may help understand altered trunk motion in anterior cruciate ligament injuries.
