Many introductory biochemistry students have problems understanding metabolism and acquiring the skills necessary to study
metabolic pathways. In this paper we suggest that this may be largely due to the use of a traditional teaching approach which
emphasises memorisation rather than understanding. We present an alternative approach to teaching carbohydrate metabolism
which is designed to promote understanding of pathways. The approach also enables regular monitoring of, and reflection on,
student progress and the identification of student reasoning and conceptual difficulties through the use of specially designed
problems. Preliminary results are presented giving examples of specific student difficulties and the extent to which they
were addressed by the alternative instructional approach. A qualitative evaluation of the approach is also presented.

We examined the associations between components of temperament and children’s word and pseudo-word reading skills, in a school-age
sample using a within-family internal-replication design. We estimated the statistical prediction of word and pseudo-word
reading in separate regression equations that included the main effects of, and two-way interaction between, Surgency and
Effortful Control. Children with better Effortful Control scores showed better reading skills. Surgency was unrelated to reading
skills, but moderated the effect of Effortful Control. The positive association between reading skills and Effortful Control
was present only for children who were low in Surgency. Thus, reading achievement in school-age children is optimized by strong
Effortful Control, but these processes may be disrupted for those children who are high in Surgency. 相似文献

The use of problem-solving in science instruction implies a change in the teacher's role from dispensing content information
to encouraging critical reflective thinking in the student. For problem-solving to become an integral part of the science
curriculum, teachers must make it the focus of their instruction. This study investigated the extent to which pre-service
primary teachers used the problem-solving approach in their science instruction. It also identified the factors affecting
their efforts to teach science using this approach. The issues considered are important in whether problem-solving becomes
part of the science curriculum, as teaching behaviour influences student learning outcomes.

The main objective of this research paper is to introduce the concept of medical libraries, and to survey the present status of medical libraries in the State of Bahrain in terms of their history, collections, staff, and services. The study gives a general background about the State of Bahrain and its libraries. It also discusses the main problems facing medical libraries in Bahrain. Finally, the study gives some recommendations for developing medical libraries in Bahrain. Personal interviews and documents were used for collecting the information. 相似文献

The aim of this study was to assess the likelihood of individuals to participate in enough physical activity to promote fitness and, more conservatively, to accrue only health benefits. Sedentary (n = 883; 20.5%) and active (n = 1144; 26.5%) groups were identified from the 1990 Allied Dunbar National Fitness Survey of English adults (n = 4316). The data were analysed using logistic regression. Participants were described using 20 variables identified from previous research, six of which made a significant contribution to the model (P < 0.05). The odds of being sedentary increased with age, self-perception of lifestyle problems, and lower scores on education, self-perception of motivation to exercise, perception of own participation in physical activity and recognition of exercising enough for health benefits. The odds of being active were associated with the opposite characteristics to those observed for sedentary behaviour. The extreme scores varied from individuals who may be 385 times more likely to be sedentary, to those who were 29 times more likely to be active, depending on scores on the selected variables. The results of this study provide a means to determine individual propensity to participate in adequate physical activity, and to identify those who may benefit most from health promotion campaigns. 相似文献

Biomechanics and motor control researchers measure how the body moves and interacts with its environment. The aim of this review paper is to consider some key issues in research methods in biomechanics and motor control. The review is organized into four sections: proposing, conducting, analysing and reporting research. In the first of these, we emphasize the importance of defining a worthy research question and of planning the study before its implementation to prevent later difficulties in the analysis and interpretation of data. In the second section, we cover selection of trial sizes and suggest that using three trials or more may be beneficial to provide more 'representative' and valid data. The third section on analysis of data concentrates on effect size statistics, qualitative and numerical trend analysis and cross-correlations. As sample sizes are often small, the use of effect size is recommended to support the results of statistical significance testing. In using cross-correlations, we recommend that scatterplots of one variable against the other, with the identified time lag included, be inspected to confirm that the linear relationship assumption underpinning this statistic is met and, if appropriate, that a linearity transformation be applied. Finally, we consider important information related to the issues above that should be included when reporting research. We recommend reporting checks or corrections for violations of underpinning assumptions, and the effect of these checks or corrections, to assist in advancing knowledge in biomechanics and motor control. 相似文献
