The purpose of this study was to assess the effects of training, modality, and redundancy on the participants' ability to apply and recall a historical inquiry strategy. An experimental research design was utilized with presentation mode as the independent variable and strategy application and strategy recall as the dependent variables. The…

The present paper examines the difficulties Greek senior high school students identify in learning Statistics and how these difficulties are related to the course's level of difficulty. Also it examines the difficulties students identify that teachers face while teaching Statistics, their suggestions for changes and how these difficulties and…

Estimation of the parameters of the Rasch model is considered when both the item parameters and the ability parameters are considered random quantities. (RB)

The study examined the ability to estimate the number of dots in Braille symbols by 21 legally blind and 21 sighted adults. Results indicated that this task was difficult for both blind and sighted subjects with little improvement over trials. Errors of underestimation exceeded errors of overestimation. (DB)

Across three experiments involving four-, five-, and six-year-olds, the same pattern of ability to sequence events was found: familiar events in forward order were the easiest to sequence, then unfamiliar events in forward order, familiar events in backward order, and finally unfamiliar events in backward order.

The determination of difficulty level of the dictation material is the crucial point in the development of speed. A three-phase process for building shorthand dictation speed is illustrated and discussed. (Author/CH)

Describes relatively simple, inexpensive employee training or guidance aids for use with straightforward, repetitive tasks and for activities calling for greater judgment, complex discrimination, and managerial or professional decision making. (LY)

The Dale-Chall Readability Formula and the Fry Readability Graph were used to analyze passages of Plato's "Parmenides," a notoriously difficult literary piece. The readability levels of the text ranged from fourth to eighth grade (Dale-Chall) and from sixth to tenth grade (Fry), indicating the limitations of the readability tests. (DF)

Properties of dichotomous Guttman-scalable items are described. Both the elements and eigenvalues of the Pearson correlation matrix of such items can be expressed as simple functions of the number of items if the score distribution is uniform and there is an equal number of items at each difficulty level. (SLD)

Community involvement in music making is a time-honored tradition that is experiencing a joyful resurgence. The word "community" can mean both an area of geography as well as a group of people coming together with a sense of purpose. In creating a community chorus, a key to its success is to place more emphasis on the second aspect. Go beyond…

When a visual search task is very difficult (as when a small feature difference defines the target), even detection of a unique element may be substantially slowed by increases in display set size. This has been attributed to the influence of attentional capacity limits. We examined the influence of attentional capacity limits on three kinds of…

According to many students, introductory physics is difficult. We are investigating what students believe makes physics difficult and what can be done to overcome these difficulties. Our investigation includes an initial free-response survey given to approximately 1400 students in an introductory physics course and a second survey, which was given…
