In this article, the authors suggest a profile-likelihood approach for estimating complex models by maximum likelihood (ML) using standard software and minimal programming. The method works whenever setting some of the parameters of the model to known constants turns the model into a standard model. An important class of models that can be…

Background: A number of disorders are associated with pragmatic difficulties. Instruments that can make subdivisions within the larger construct of pragmatics could be important tools for disentangling profiles of pragmatic difficulty in different disorders. The deficits underlying the observed pragmatic difficulties may be different for different…

The present studies were conducted to investigate students' conceptions of distinct constructivist assumptions. To that end, a questionnaire was developed containing statements about four constructivist assumptions: The importance of knowledge construction, cooperative learning, self-regulation, and the use of authentic problems together with…

This article reports on the development of a short questionnaire to measure work engagement--a positive work-related state of fulfillment that is characterized by vigor, dedication, and absorption. Data were collected in 10 different countries (N = 14,521), and results indicated that the original 17-item Utrecht Work Engagement Scale (UWES) can be…

The construction and validation of a tutor evaluation questionnaire are described. The importance of the tutor in problem-based learning requires assessment of staff conducting this role. After a pilot study in 1990-91 with 100 students and 150 tutors who identified important tutor skills, a questionnaire was prepared. This questionnaire was…

Data from 211 adult students (ages 20 to 75) at the Open University, The Netherlands, were used to construct and test an instrument to measure learning styles and regulation processes. Test development was guided by a three-tiered model of self-regulation encompassing: (1) cognitive learning processes (deep, surface, elaborative); (2) regulation…
