There are usually limited user evaluation of resources on a recommender system, which caused an extremely sparse user rating matrix, and this greatly reduce the accuracy of personalized recommendation, especially for new users or new items. This paper presents a recommendation method based on rating prediction using causal association rules.…

There has been much discussion about quantitative and qualitative approaches to research in different disciplines. In the behavioural and social sciences, these two paradigms are compared to reveal their relative strengths and weaknesses. But the debate about both traditions has commonly taken place in academic books. It is hard to find an article…

The purpose of the research paper was to investigate the effect of eclectic learning approach on the academic achievement and retention of students in English at elementary level. A sample of forty students of 8th grade randomly selected from Government Boys High School Khurram District Karak was used. It was an experimental study and that's why…

This discussion paper compares and contrasts "inductive" and "deductive" research approaches as described by Trochim (2006) and Plano Clark and Creswell (2007). It also examines the "exploratory" and "confirmatory" approaches by Onwueghuzie and Leech (2005) with respect to the assumption each holds about the nature of knowledge. The paper starts…

As a result of the generally low quality of child care in the United States and the increased emphasis on accountability in education policy, quality rating systems (QRSs) are proliferating in the child-care arena. QRSs assess child-care providers on multiple dimensions of quality and integrate these assessments into an easily understood summary…

In this study, the consistency of on-task data collected across raters using either a Daily Behavior Report Card (DBRC) or systematic direct observation was examined to begin to understand the decision reliability of using DBRCs to monitor student behavior. Results suggested very similar conclusions might be drawn when visually examining data…

Examined the discriminant validity, criterion-related validity, and between-spouse agreement for a marital intake interview as a function of interview method and valence of interview items. Results suggested a high degree of discriminant validity, higher interspouse correlations during joint interviews, and higher indices of criterion related…

Grounded theory, generated from data systematically obtained through the constant comparative method, is suggested as a research strategy for higher education. Greater emphasis is placed on qualitative data while using quantitative data when obtainable and pertinent. Higher education research can thereby be redirected to development of theory.…

The objective was to determine the quality of the data submitted by seven of these institutions, and to suggest actions for improving the quality of the HEGIS information…

Issues in collecting data on the classroom performance of teachers are discussed, with a focus on written descriptions of teacher behavior in contrast with videotaped observations. The central issue in this comparison is the comparability of the information when it is observed live and when it is simply recorded on videotape. The fundamental…
