A simple in-class demonstration of integral Calculus for first-time students is described for straightforward whole number area magnitudes, for ease of understanding. Following the Second Fundamental Theorem of the Calculus, macroscopic differences in ordinal values of several integrals, [delta]"F"(x), are compared to the regions of area…

This book addresses the validity of think-aloud protocols (TAPs) in L2 writing research through a mixed methods study and proposes effective approaches for their valid implementation. The book uncovers the reactive effects that TAPs have on L2 writing performance and processes, and examines how individual factors moderate this reactivity. It…

We have revamped a classic analytical chemistry laboratory experiment, "Determination of an Unknown Acid", to provide students an opportunity to learn about new advances in the material sciences and their applications in analytical chemistry in an effort to reinforce the key concepts of chemical analysis. Specifically, students were…

Individuals' perceptions of their own level of cognitive ability are expressed through self-estimates. They play an important role in a person's self-concept because they facilitate an understanding of how one's own abilities relate to those of others. People evaluate their own and other persons' abilities all the time, but self-estimates are also…

The Guidelines for Good Practice of the European Association for Language Testing and Assessment (EALTA) stress the importance of collaboration between all parties involved in the process of developing instruments, activities and programmes for testing and assessment. Collaboration is considered to be as important as validity and reliability,…

Internal and external validity are key concepts in understanding the scientific method and fostering critical thinking. This article describes a class demonstration of a "botched" experiment to teach validity to undergraduates. Psychology students (N = 75) completed assessments at the beginning of the semester, prior to and immediately following…

This study sought to explore the emotional intelligence of Form One mathematics and science teachers. The emotional intelligence of the teachers was determined using the Emotional Intelligence for Mathematics and Science Teachers (EIMST) survey instrument. It was adapted and adopted from related instruments and then pilot tested for validity and…

The present study had three purposes. The first was to further explore the psychometric properties of the Preferred Thinking Styles in Teaching Inventory [Zhang, L. F. (2003). "The preferred thinking styles in teaching inventory." Unpublished test. The University of Hong Kong: Hong Kong]. The second was to test the hypothesis that the…

This study found that the restructured National Board Dental Examination Part II is a reliable test assessing a full range of cognitive behaviors, and a unidimensional test of comprehensive general dentistry, suggesting better testing of knowledge and problem-solving skills than on the traditional examination. Performance on the pilot and…

A study analyzed validity and reliability of grades and credits earned by college students in five departments, as indicators of student learning. Results indicate positive, strong correlation between faculty-assigned grades and student performance on external criterion measures. Validity of credits was not as clear. Strong and consistent evidence…

Organizational theorists have viewed organizations as "mini-societies" based upon commonly held cultural values and assumptions, which may serve to revolutionize organizational practices or to bring about new organization structures. The middle school is an example of an educational institution that has arisen as a result of a particular set of…

This study investigated the nature and validity of teacher judgments about student motivation as part of a project related to the teaching of mathematics. The study examined: (1) the degree of correlation between teachers' and students' assessments of students' motivation regarding mathematical topics; (2) the stability of teachers' and students'…

This study investigated the testing of speaking vocabulary in English as a Second Language (ESL) at a university in Hawaii. A Speaking Vocabulary Test (SVT) was developed and piloted with college students. Test-takers (n=37) were divided into three groups: native English-speaking freshmen and sophomores; non-native English-speaking freshmen,…

This conceptual expression of "task interdependence," or role coupling, derived from research of elementary teachers in self-contained schools and team teaching schools, recommends that organizational theory provide clear concepts and measures to capture significant variations among schools. Research, measuring the…

A Dutch study of the relationship between different student cognitive styles and foreign language achievement focused on the development and analysis of a grammar test for English as a second language. The test consists of ten subtests requiring the student to manipulate aspects of English syntactic, morphosyntactic, and morphological structure.…
