Organic chemistry is a traditionally difficult subject with high failure & withdrawal rates and many areas of conceptual difficulty for students. To promote student learning and success, four undergraduate organic chemistry and spectroscopy courses at the first to third year level (17-420 students) were "flipped" in 2013-2014. In the…

This study explored the potential effect of college students' self-generated computerized mind maps on their reading comprehension. It also investigated the subjects' attitudes toward generating computerized mind maps for reading comprehension. The study was conducted in response to the inability of the foundation-level students, who were learning…

Provides tables of critical values for determining statistically significant discrepancies between Wechsler Verbal/Performance IQ and Wechsler Individual Achievement Test subtests and composite scores based on predicted-achievement method. Recommends that tables be used when statistically significant and diagnostically meaningful Verbal…

Explains that an initial criterion to determine severe discrepancies and relative strengths and weaknesses is significant difference between regressed standard scores. Presents tables as convenient method to determine magnitude of discrepancy required for significance at common reliability and intercorrelation values. Shows prevalences of…

In the educational research literature, alpha and p are often conflated. Paradoxically, alpha retains a prominent place in textbook discussions, but it is often supplanted by p in the results sections of journal articles. Because alpha and p have unique uses, researchers should continue to employ both conventions in summarizing the outcomes of…

Order analysis, a technique to isolate unidimensional hierarchies representing multidimensional structure of binary data, is reviewed. Several theoretical flaws inherent in the probalistic version are presented. Suggestions of possible directions for future research are offered. (Author)

Considers relationship between statistically and clinically significant change. Sees Jacobson and Truax's index of clinically significant change as neglecting possible confounding of improvement rate estimates by regression to the mean. Describes alternative method (Edwards-Nunnally method) that incorporates an adjustment that minimizes this…

Considered methods of evaluating the pattern of subtest scores on the Wechsler Adult Intelligence Scale-Revised. The rationale and method for calculating the size of the significant difference between a subtest and the mean of the subtests scores for an individual are described. (JAC)

Addresses the need of technical communicators to become critical readers of empirical research. Presents simple definitions of selected research designs and statistical concepts. Accompanies these definitions with concrete examples related to the field of technical communication research. (SR)

This review of the procedures involved in using path analysis provides guidelines for more effective future utilization of recursive path analysis in the field of family studies. (Author)

The use of measures of magnitude of effect has been advocated as a way to go beyond statistical tests of significance and to identify effects of a practical size. They have been used in meta-analysis to combine results of different studies. Describes problems associated with measures of magnitude of effect (particularly study size) and…
