Although teacher motivation is posited to matter for students' learning experiences, this remains largely uninvestigated, particularly in higher education. In two studies, we analyzed the role of education teachers' achievement goals and self-efficacy experiences. Study 1 (k = 166 teachers, n 2,106 students), assessed motivations at semester start, course-specific perceptions teaching quality (...

the objectives of this study were (a) to examine the writing performance of l2 learners on the level-specific tasks based on common european framework of reference (cefr) and (b) to investigate whether there was any difference between the students' self-assessed level of writing and the writing level reported by the raters. this study was conducted with 138 iranian students at ba and ma levels ...

A method for determining the parameters of a fuzzy discriminant function from set diagnostic test results is considered. These tests are basis training sample controlling level knowledge in nominal rating scales automated learning systems. The fuzziness measuring solving control problems, as well classification objects sample, taken into account. has specific versatility and allows building sim...

Many recent studies of trust and reputation are made in the context of commercial reputation or rating systems for online communities. Most of these systems have been constructed without a formal rating model or much regard for our sociological understanding of these concepts. We first provide a critical overview of the state of research on trust and reputation. We then propose a formal quantit...

The evolution from static to dynamic electronic learning environments has stimulated the research on adaptive item sequencing. A prerequisite for adaptive item sequencing, in which the difficulty of the item is constantly matched to the knowledge level of the learner is to have items with a known difficulty level. The difficulty level can be estimated by means of the item response theory (IRT),...
