Stability of repeated student evaluations of teaching in the second preclinical year of a medical curriculum

The second preclinical year of the medical curriculum at the Medical Faculty of the University of Lausanne in Switzerland includes nine multidisciplinary organ-system-oriented modules consisting of lectures and problem-based-learning tutorials. This study reports the experience accumulated with the evaluation of lectures during the academic years 1998–1999 and 1999–2000. The ratings of the different modules were highly variable, indicating the ability of students to have a critical view on the teaching and the teachers. There was a close to very close correlation between the ratings obtained during the two study years. The high discriminative capacity of students in evaluating the teaching and the teachers was also supported by their critical point of view expressed in free comments. Our observations stress therefore the reliability of teaching evaluations systematically performed by medical students.     

Effects of instructional strategies using cross sections on the recognition of anatomical structures in correlated CT and MR images

This research is an effort to best utilize the interactive anatomical images for instructional purposes based on cognitive load theory. Three studies explored the differential effects of three computer‐based instructional strategies that use anatomical cross‐sections to enhance the interpretation of radiological images. These strategies include: (1) cross‐sectional images of the head that can be superimposed on radiological images, (2) transparent highlighting of anatomical structures in radiological images, and (3) cross‐sectional images of the head with radiological images presented side‐by‐side. Data collected included: (1) time spent on instruction and on solving test questions, (2) mental effort during instruction and test, and (3) students' performance to identify anatomical structures in radiological images. Participants were 28 freshmen medical students (15 males and 13 females) and 208 biology students (190 females and 18 males). All studies used posttest‐only control group design, and the collected data were analyzed by either t test or ANOVA. In self‐directed computer‐based environments, the strategies that used cross sections to improve students' ability to recognize anatomic structures in radiological images showed no significant positive effects. However, when increasing the complexity of the instructional materials, cross‐sectional images imposed a higher cognitive load, as indicated by higher investment of mental effort. There is not enough evidence to claim that the simultaneous combination of cross sections and radiological images has no effect on the identification of anatomical structures in radiological images for novices. Further research that control for students' learning and cognitive style is needed to reach an informative conclusion. Anat Sci Ed 1:75–83, 2008. © 2008 American Association of Anatomists.     

Fulfilment of the basic psychological needs of student teachers during their first teaching experiences

This study focuses on an under-researched area, namely the fulfilment of basic psychological needs of student teachers during their first teaching experiences. Based on the Self-determination Theory of Ryan and Deci [(2002). Overview of self-determination theory: An organismic dialectical perspective. In E.L. Deci, R.M. Ryan (Eds.), Handbook of self-determination research (pp. 3–33). Rochester: The University of Rochester Press] and the work of Epstein [(1998a). Cognitive-experiential self-theory: A dual-process personality theory with implications for diagnosis and psychotherapy. In R.F. Bornstein, J.M. Masling (Eds.), Empirical perspectives on the psychoanalytic unconscious (pp. 99–140). Washington, DC: APA; (1998b). Constructive thinking: The key to emotional intelligence. Westport: Praeger], it could be demonstrated that need fulfilment has a strong influence on student teachers’ teaching experiences, especially in a non-rational way, for instance through feelings and images. Thwarting of the needs appears to be correlated with images showing fight, flight, and freeze tendencies, whereas need fulfilment concurs with flow tendencies. The fulfilment of the need for competence, relatedness, and autonomy in student teachers is considerably less than in experienced teachers. We discuss the consequences for research in this field, and recommendations for teacher education.     

The current status of instructional design theories in relation to today's authoring systems*

It is of course very difficult to accurately project important characteristics of the future state of any rapidly evolving field, and the field of authoring systems for computer‐assisted instruction (CAI) is no exception. However, strong trends in evolving CAI systems of today would seem to indicate some important characteristics of the software systems underlying tomorrow's automated instructional systems. Under the premise that form follows function, this paper will explore the functional impetus of some of the most important trends extant in terms of their roots in a powerful, emerging technology of instructional design. This technology promises to complement the advancing hardware and software technologies, by supplying that sine qua non of successful instructional materials. It is inevitable that systems of the future will make (and indeed are making) significant accommodations of this vital technology as it matures, and therefore some important characteristics of tomorrow's systems can be predicated upon what is already known of this technology of instructional design.     

The effects of constructivist learning environments: a commentary

This special issue on the effects of constructivist learning environments is based on a symposium organized during the last annual meeting of the American Educational Research Association in Chicago. The studies in this issue not only provide an overview of the multitude of forms a constructivist learning environment can take, they also provide the reader with an overview of recent advances in this domain of research. The present discussion article provides a critical reflection on the studies in this special issue and tries to identify their prospects and limitations.     

Differential second-order aversive conditioning using contextual stimuli

Two experiments were conducted to determine if contextual stimuli used as S₂ in a higher-order differential conditioning procedure would control the performance of rats. Discrete stimuli were first paired with footshock in a separate training context. During second-order training, a shock-associated discrete stimulus was presented in one of two discriminable observation chambers. Over 4 days of training, subjects engaged in more freezing in the context associated with an excitatory discrete S₁, relative to a context in which no discrete stimulus, or a stimulus that had been explicitly unpaired with shock delivery, was presented. After acquisition of the second-order discrimination, animals were returned to the original training context where they received a “signaled inflation” treatment designed to change the current value of S₁, and the US. This postconditioning manipulation did not selectively affect performance of defensive freezing or conditional analgesia in S₂.     

Dancing in Fetters? Chinese Principals’ Perceptions of the Effects of Finnish Training Programs

Although there is an increased interest in overseas training for educational leaders in China, little is known about the value of such programs. This qualitative case study explores Chinese school principals’ perceptions of leadership practices and professional development after undertaking a Finnish training program. The article also explores difficulties related to different educational contexts when an attempt is made at applying the Finnish education experience to China. Famed for its excellent education, Finland is currently actively involved in exporting its education by providing such training programs to the whole world. Data was collected by semi-structured interviews with six Shanghai principals. The results showed a certain level of satisfaction but also needs for improvement. It thus appears that such an overseas training program can play a positive but limited role in expanding Chinese principals’ leadership practices and professional development.
