We reviewed 14 experimental studies comparing different preference assessments for individuals with developmental disabilities that were published in peer-reviewed journals between 1985 and 2012. Studies were summarized based on the following six variables: (a) the number of participants, (b) the type of disability, (c) the number and type of…

This study proposes a new method named the IIS-map-based method for analyzing interactions in face-to-face collaborative learning settings. This analysis method is conducted in three steps: firstly, drawing an initial IIS-map according to collaborative tasks; secondly, coding and segmenting information flows into information items of IIS; thirdly,…

Analyzes advantages and disadvantages of methods of selecting sample sizes in multiple regression. Discusses importance of cross-validity to prediction studies. Describes categories of sample size selection methods: cross-validation approaches, rules of thumb, and statistical power methods. Uses multiple examples to present the precision power…

Earlier studies have suggested that higher education institutions could harness the predictive power of Learning Management System (LMS) data to develop reporting tools that identify at-risk students and allow for more timely pedagogical interventions. This paper confirms and extends this proposition by providing data from an international…

Surveys current methodologies and problems in enrollment forecasting at the State and institutional level. (Author/MLF)

Four commonly employed procedures were repeatedly applied to computer-simulated samples to provide comparative data pertaining to two questions: (a) which procedure can be expected to produce and equation that yields the most accurate predictions for the population, and (b) which procedure is most likely to identify the optimal set of independent…

Finds that reasonably accurate predictions of election results can be made based on selected phonetic features in candidates' names. Discusses the emotive effect of speech sounds, distinguishes them from other types of meaning, surveys previous types of studies, describes the development of the author's analytical model and its attributes, and…

The scientist who uses the experimental form does so in order to explain that which is verified through prediction. The prerequisites for prediction include a universe that is ordered, stable, independent, and knowable. Some assumptions of the predictive argument with respect to communication research are: the operating elements of the message are…

In this paper, we explore the rules that determine intuitive predictions and judgments of confidence and contrast these rules to the normative principles of statistical prediction. (Author)

Retrospective technology assessment (RTA) is the use of historical research to assess current and future technology issues. This paper uses the introduction of the videocassette recorder (VCR) as an RTA case study, focusing on the broadcasting and advertising trade presses and their forecasts of the VCR's potential impact on broadcasting. Trade…

Applies the Box-Jenkins time series methodology to enrollment data for the Virginia community college system. Describes the enrollment data set, the Box-Jenkins approach, and the forecasting results. Discusses the value of one-quarter ahead enrollment forecasts and implications for practice. Provides a technical discussion of the model. (DMM)

To enhance knowledge of media consumption processes, a study compared the abilities of six alternative gratification models to predict media satisfaction, specifically, satisfaction with television news. The models were three different formulations of gratifications sought/obtained discrepancies--two emphasizing gratifications obtained and one…

Science plays an extremely important role in predicting the future of social phenomena, including pedagogy and andragogy. Research in these areas must be based on an interdisciplinary, multidisciplinary, systemic, and structural approach that is based on the assumption that upbringing and education are specific phenomena in which human…
