In 1995, Theeuwes and Godthelp published a paper called "self-explaining roads," in which they argued for the development of a new concept for approaching safe road design. Since this publication, self-explaining roads (SER) became one of the leading principles in road design worldwide. The underlying notion is that roads should be…

Computer simulation can be used to demonstrate why the unbiased sample variance uses degrees of freedom (n-1). This is first demonstrated for sampling from a normal random variable, and in additional simulations for some selected non-normal random variables, namely, chi-square and binomial.

This paper develops a theoretical framework that could facilitate the application of the Autovalutazione, Valutazione periodica, Accreditamento (AVA) method in Italian universities, trying to simplify the use of this approach, and to cover the existing gap between Italy and others European academic institutions. The new competitive environment in…

Although there is general agreement that doctoral students and their experiences are diverse, in what respect this is true is in question. Most institutional practices in the collection of data in this regard have been established to satisfy government reporting requirements and concerns, such as funding, participation and equity, and efficiency.…

Many students lack problem-solving skills. As teenagers, they tend to blame external forces or other people when something goes wrong, instead of trying to understand the root cause to prevent it from happening again. This article discusses the Lean Six Sigma methodology for problem solving, which the Board of Cooperative Educational Services in…

Physical science courses have historically been taught from a variety of perspectives or emphases. In many cases, the instructor decides on the perspective and textbook for nonscience majors, so students rarely have a voice in the decision. This top-down approach and a potential gap between what instructors and students expect from a general…

In "Educations in Ethnic Violence", Matthew Lange explores the effects education has on ethnic violence. Lange contradicts the widely-held belief that education promotes peace and tolerance. Rather, Lange finds that education commonly contributes to aggression, especially in environments with ethnic divisions, limited resources, and…

Students in higher education today are technologically savvy and expect faculty to use myriad web technologies for course delivery. This includes taking advantage of email, course web sites, and online learning communities. However, expectations now also include RSS, blogs, web-, pod-, and vod-casting, extending the classroom experience to provide…

Researchers often have one or more theories or expectations with respect to the outcome of their empirical research. When researchers talk about the expected relations between variables if a certain theory is correct, their statements are often in terms of one or more parameters expected to be larger or smaller than one or more other parameters.…

Accountability and performance incentive plans in education are compromised by goal distortion, gaming, and corruption. Education policy makers who design such plans have paid insufficient attention to similar experiences in other fields. This paper describes institutions in health care, job training and welfare administration, and in the private…

A procedure for developing a nomogram that depicts expectancy of success on a criterion from performance on two predictors is presented. Data from 574 medical students attending Michigan State University College of Human Medicine's classes of 1979 through 1984 were used to develop a model for predicting the expectancy of success on Part I of the…

This appendix accompanies "Gaining Ground in the Middle Grades: Why Some Schools Do Better. A Large-Scale Study of Middle Grades Practices and Student Outcomes. Initial Research Report." This appendix focuses on the findings and domain comparisons of the study. This appendix contains the following: (1) Decision Rules; (2) Full Set of…
