Use of item response theory in marketing research

Research article of American Journal of Educational Research and Reviews Use of item response theory in marketing research Hyo Jin Eom1, John Hulland2, Jordan M. Wheeler2, Seock-Ho Kim2        1Korea University, 2University of Georgia There are three purposes of this paper. The first is to present a brief introduction to item response theory in conjunction with marketing research. The second is to present a review of the current uses of item response theory in representative marketing research journals. The third is to present an example that illustrate and contrasts classical test theory and item response theory approaches to item and scale analysis. Several item response theory relevant papers were recently published in various marketing research journals. Because models under item response theory, from simple to complex, were used without any systematic introduction in marketing research, this paper briefly presents the main concepts in item response theory. A content analysis was done for the second purpose with 30 item response theory relevant articles in marketing research journals. Articles were sorted based on the taxonomy of item response theory models. Many articles reviewed relied on some type of unidimensional dichotomous item response theory models. Articles published recently within the past 10 years used more complicated item response theory models, both mathematically and statistically, than other previously published articles in marketing research journals. Lastly, data from a scale with three Likert-type items of four response categories were analysed using a traditional approach based on item statistics and coefficient alpha as well as using an item response theory approach by employing the graded response model. Main concepts of item response theory were explicated with figures. Keywords: item response theory; marketing research; measurement issues; Rasch model ...

The Analysis of Frequency Terms Used in Rating Scales

Research article of American Journal of Educational Research and Reviews The Analysis of Frequency Terms Used in Rating Scales Seock-Ho Kim1, Hyo Jin Eom2 1The University of Georgia, 2Korea University The purpose of this paper is to provide a contemporary analysis of frequency terms commonly used in rating scales that are based on differing degrees of frequency with which events happen. A total of 20 frequency terms was analyzed using empirical data as well as employing a lexical database. Use of clearly separable frequency terms is imperative for the construction of a set of rating scales as an effective measuring instrument. Keywords: cluster analysis, frequency terms, rating scale, synset ...

Exploration of explanatory factors underlying teachers’ perception of learning difficulties in mathematics in interaction with student performances

Research article of American Journal of Educational Research and Reviews Exploration of explanatory factors underlying teachers' perception of learning difficulties in mathematics in interaction with student performances  Thomas Rajotte1*, Raphaelle Dufour1, Emilie Boivin1  1Department of Education, Université du Québec à Rimouski, Québec, Canada. This study project contributes to documenting the subject of learning difficulties in mathematics [1-4]. In this research, we aimed to verify what are the main explanatory factors underlying teachers’ perception of learning difficulties in mathematics and in relation to student performance in a problem-solving test. To meet the objectives of the study, we implemented a correlational quantitative data analysis devise with the participation of 262 primary school students. Regression analyzes were performed. The results of the analyzes show that the performance in solving a written mathematics questionnaire is explained mainly by socio-demographic variables associated with the students and by factual variables relating to the conditions for taking the questionnaires. Moreover, the teacher’s perception of student performance in mathematics is mainly explained by variables directly related to the student or to the teacher’s vision of the student’s potential for success at school.

Impact of the edTPA on teacher candidates’ perceptions of preparedness to teach

Research article of American Journal of Educational Research and Reviews Impact of the edTPA on teacher candidates’ perceptions of preparedness to teach Nancy K. DeJarnette1*, Judith Moeller1, Kathleen Wallace1 1University of Bridgeport. This longitudinal case study conducted at a private University in the northeastern United States explored the impact of the edTPA assessment and preparation process as an embedded component of the University’s educator preparation program. The study tracked 59 graduate level candidates from entry into the program through candidate licensure. The researchers examined the impact of the edTPA preparation process on teacher candidates’ perceptions of their readiness to teach in comparison to their actual readiness to teach as indicated by their edTPA portfolio passing score. The University’s School of Education has an estimated 30% ethnic diversity population, thus a second research question compared perceptions of readiness to teach of candidates of color to those of Caucasian peers. Framed by Bandura’s (1977) self-efficacy theory, this study contributes to the research on the edTPA as an efficacious and inclusive evaluation tool, particularly within diverse schools of education. Keywords: edTPA, candidates of color and edTPA, teacher candidates, self-efficacy in teacher candidates, teacher education ...
