Green, Samuel B. – Multivariate Behavioral Research, 1991
An evaluation of the rules-of-thumb used to determine the minimum number of subjects required to conduct multiple regression analyses suggests that researchers who use a rule of thumb rather than power analyses trade simplicity of use for accuracy and specificity of response. Insufficient power is likely to result. (SLD)

Hu, Li-tze; Bentler, Peter M. – Structural Equation Modeling, 1999
The adequacy of "rule of thumb" conventional cutoff criteria and several alternatives for fit indices in covariance structure analysis was evaluated through simulation. Analyses suggest that, for all recommended fit indexes except one, a cutoff criterion greater than (or sometimes smaller than) the conventional rule of thumb is required…

Farrar, Nicholas; Trorey, Gill – Journal of Vocational Education and Training, 2008
This study attempts to further our understanding of how expertise is acquired in a specific vocational context. Using unstructured interviews with both individuals and groups, carried out whilst engaged in practice, it examines what happens when dry stone wallers are developing their skills, how they gain expertise and how they communicate their…

English, Fenwick W.; Bolton, Cheryl L. – Journal of School Leadership, 2008
This article is a report on a study of the use of heuristics, shortcuts, and rules of thumb by middle-line managers in institutions of higher education in the United States and the United Kingdom. Using a nonprobability convenience sample, the coinvestigators interviewed 13 middle-line managers over 5 months from eight institutions. The results…

Lovoy, Thomas – College Teaching, 2004
English teachers, as well as teachers within other disciplines, often boil down abstract principles to easily explainable bullet points. Students often pick up and retain these points but fail to grasp the broader contexts that make them relevant. It is therefore sometimes helpful to revisit some of the more common of these "rules of thumb" to…

Montgomery, Malcolm – Campus Technology, 2008
As technology and teaching requirements continue to evolve, one would think the choice of which data projector to buy would be easier because there now are more products with more capabilities. Yet just the opposite is true: The sheer number of projectors and myriad combinations of available features can be overwhelming, making it really tough to…

Booth, Char – Public Services Quarterly, 2009
This will be my first time authoring this column, and I'm delighted to have the opportunity it presents to explore the intersection of library technology and public services. As the recent title of the 2008 Internet Librarian conference indicates, "Beyond Library 2.0: User-Focused Tools and Technologies," the tide of what for several years has…

Frey, B.B.; Petersen, S.; Edwards, L.M.; Pedrotti, J.T.; Peyton, V. – Teaching and Teacher Education: An International Journal of Research and Studies, 2005
In student assessment, teachers place the greatest weight on tests they have constructed themselves and have an equally great interest in the quality of those tests. To increase the validity of teacher-made tests, many item-writing rules-of-thumb are available in the literature, but few rules have been tested experimentally. In light of the…

Murray, Donald M. – Language Arts, 1982
Discusses 10 rules of thumb for writing educational research reports that are concise and accessible. The principles include writing in terms of people, emphasizing the positive, editing for simplicity, and breaking any of the previously discussed rules when necessary. (HTH)

Dickerson, Richard E. – Intelligence, 2006
Plots of mean IQ and per capita real Gross Domestic Product for groups of 81 and 185 nations, as collected by Lynn and Vanhanen, are best fitted by an exponential function of the form: GDP = "a" * 10["b"*(IQ)], where "a" and "b" are empirical constants. Exponential fitting yields markedly higher correlation coefficients than either linear or…

Kennedy, Mary M. – Journal of Teacher Education, 2006
The author challenges the role of knowledge in teaching by pointing out the variety of issues and concerns teachers must simultaneously address. Teachers use two strategies to manage their multidimensional space: They develop integrated habits and rules of thumb for handling situations as they arise, and they plan their lessons by envisioning them…

Lundgren, Anders – Science & Education, 2006
This paper is a study of textbooks in chemical technology in Sweden during the industrialisation in the 19th century. In this period, teaching in technological education in general became more and more founded on science. However, there existed very few textbooks in chemical technology, and it is argued that the reason was that the essentials of…
