Abstract

Learning to drive a motor vehicle is important for the mobility of the majority of people in industrialized countries. Although a great deal is known about the acquisition of psychomotor skills in the laboratory and in some other practical settings, there has been little scientific study of learning to drive. One major practical question concerns the value of formal tuition with a qualified instructor and informal practice with friends or relatives. This paper reports a cross-sectional study of 805 learner drivers in the UK who had undergone at least 5 h of formal tuition to examine associations between their history of formal tuition and practice and current levels of skill and confidence as assessed by both pupils and their instructors. The results indicated an increase in instructor ratings of pupil skill with both increasing practice and tuition. However, the relationship between tuition and instructor-rated skill was only observed in pupils who had had no practice. Pupils' self-confidence did not increase with either tuition or practice; instructors' feelings of confidence in and safety with the pupil increased with pupils' prior hours of practice but not tuition. Instructors' ratings of the likelihood that pupils would pass the driving test first lime were positively associated with prior hours of practice and negatively associated with prior formal tuition. The results suggest that informal practice constitutes an important element of the process of learning to drive. Longitudinal and experimental studies are now required to confirm this finding and to establish whether recommendations should be made for a component of driving tuition involving supervised practice.  相似文献

作为机械类专业中的一门实践类课程,UG课程的教学效果不够理想,主要原因在于其知识点中的重点难点较多,学生对其理解不够透彻,以及教材的工程实用性不够强.而微课,作为一种新型的教学形式,对于改善UG课程的教学效果有着重要的作用.在具体的UG课程的微课设计中,教师应注重微课内容的选取、微课导入环节及教学过程的设计以及微课教学视频的展示效果,充分发挥微课在UG课程中的教学补充和延伸作用.  相似文献

Within the framework of models of central capacity, automatization (as indicated by decreasing dual-task interference over the course of practice) can be attributed to a change of the performance-resource function, such that performance becomes better for a given amount of capacity, and performance decrements become smaller for a given reduction in capacity. In general, automization is considered as a change in human information processing that makes it less susceptible to disturbances by secondary tasks. By way of simulation it is demonstrated that in user-machine systems ‘pseudoautomatization’ can occur. This is a decline of dual-task interference without any alteration of the secondary-task effects on human information processing such as are thought to underlie automatization. Pseudoautomatization is discussed as a potential fallacy in interpreting system-performance measures and as a means by which human operators potentially immunize user-machine systems against disturbances of human information processing.  相似文献

Using an instrumented car driven in normal traffic, we assessed the driving skills of trained experts, of normal, experienced drivers, and of novices. Previous research suggests a fairly simple picture of improvement in driving skills with experience, and for aspects of car control (e.g., steering path, speed of manoeuvres) our results confirm this: normals largely resembled experts, while novices performed more poorly. There are reasons to suspect, however, that experience may not always be so beneficial. For example, one important variable may be feedback, or information indicating to the driver that a particular action is or is not important in terms of overall goals (progress, safety, etc.). Where feedback is good, simple experience may bring expertise, but where feedback is poor, skills may fail to improve or even deteriorate once explicit tuition is removed. Correspondingly, our findings showed that for scanning patterns (e.g., mirror checking), anticipation (e.g., braking into an intersection), and safety margin (e.g., close following on the motorway), it was often the normal, experienced drivers who performed worst, novices sometimes even resembling experts. The data make it clear that for many aspects of driving skill experience is no guarantee of expertise.  相似文献

Human activity can be seen as an intentional, context-dependent enterprise explained through meanings the actors attach to their activity and their directly observable interactions with the environment. The authors have demonstrated previously a new conceptual framework to describe the anaesthetist's activity. One of the central concepts besides orientation is habit of action referring to the way in which the actor has organized his actions when interacting with his environment, in this case a patient with unique physiological potentials, information monitors and anaesthetic drugs. The activity dependent on contingent, particular circumstances, needs to be studied as it appears in a natural situation. Using an idiographic study design the authors have examined the activity of eight expert anaesthetists in clinical settings to determine the characteristics of their habits of action. To capture the fleeting circumstances during the anaesthetic process, a wide observational basis was necessary. It consisted of videotapes, detailed expert observations, and interviews. The conceptual analysis of the subject, habit of action, is described step-by-step. Two distinct habits of action could be identified, confirming earlier results. The interpretative habit of action was characterized by extensive use of situational information in order to construct a cumulative conception of the patient's physiological potentials to control the process accurately. Moreover, rich dialogue between formal professional knowledge and patient-specific, particular knowledge was evident. The reactive habit of action was characterized by a tendency to regulate the process by means of predetermined conventional ranges of measured patient parameters shown by monitors. The authors discuss their methodological solutions and results, and explicate their differences to the earlier approaches.  相似文献
