Contemporary commentary notes that students are frequently ahead of their teachers in their ability to manipulate and be creative with the internet, digital programs, and mobile technology. In this context it is important to ask, ‘What knowledge do teachers need to teach in the contemporary context where texts are elaborately multimodal, constructed not just of print but of image, sound, and movement?’ This paper proposes some signposts to assist teachers with navigating in this environment. Using teachers’ and researchers’ reflections on practices in a diverse range of settings, both primary and secondary, the analysis explicates the challenges that teachers face in this multimodal context and elucidates some ways they can effectively operate within it. In particular, it argues that it is teachers’ expertise as analysts and critics of texts that needs to guide their planning and teaching in this ‘new’ text world. 相似文献
SOME significant problems in the design of research with subjects having an intellectual disability are identified. A lack of agreement on the nature of intellectual disability in relation to brain impairment, and discrepancies in the interpretation of deficits in relation to information processing concepts create problems in the definition of subject groups and interpretation of results. Much of the research uses normal subject groups for comparison, matched with disabled groups for either mental age, chronological age, or both, and this has led to further problems in the criteria and procedures used for matching, particularly for mental age. Further difficulties are encountered in variability both within and between subject groups, affecting reliability of results and making replication of studies difficult. In addition, task demands, particularly in relation to variables other than those under immediate investigation, are not always equivalent for all subject groups. Some suggestions are made for reducing or eliminating the effects of some of these problems in experimental research, and the use of alternative designs which take subject variability into account is recommended. 相似文献
This article tests the hypothesis that self-development plays a role in the offset of childhood amnesia; assessing the importance of both the capacity to anchor a memory to the self-concept, and the strength of the self-concept as an anchor. This research demonstrates for the first time that the volume of 3- to 6-year old's specific autobiographical memories is predicted by both the volume of their self-knowledge, and their capacity for self-source monitoring within self-referencing paradigms (N =186). Moreover, there is a bidirectional relation between self and memory, such that autobiographical memory mediates the link between self-source monitoring and self-knowledge. These predictive relations suggest that the self-memory system is active in early childhood. 相似文献
Communication is inextricably important to instructional design and performance‐based training. Promoting effective communication as an integral part of the performance support system improves professional instructional design functions and offers greater avenues for meaningful discourse among end users of the instruction. In this article, we highlight communication in performance training and instruction for meaningful learning and effective exchange of knowledge. Internal and external communications are discussed as a means to promoting successful relationships, commitment, and ownership. 相似文献
Force plates represent the “gold standard” in measuring running kinetics to predict performance or to identify the sources of running-related injuries. As these measurements are generally limited to laboratory analyses, wireless high-quality sensors for measuring in the field are needed. This work analysed the accuracy and precision of a new wireless insole forcesensor for quantifying running-related kinetic parameters. Vertical ground reaction force (GRF) was simultaneously measured with pit-mounted force plates (1?kHz) and loadsol® sensors (100?Hz) under unshod forefoot and rearfoot running-step conditions. GRF data collections were repeated four times, each separated by 30 min treadmill running, to test influence of extended use. A repeated-measures ANOVA was used to identify differences between measurement devices. Additionally, mean bias and Bland–Altman limits of agreement (LoA) were calculated. We found a significant difference (p?.05) in ground contact time, peak force, and force rate, while there was no difference in parameters impulse, time to peak, and negative force rate. There was no influence of time point of measurement. The mean bias of ground contact time, impulse, peak force, and time to peak ranged between 0.6% and 3.4%, demonstrating high accuracy of loadsol® devices for these parameters. For these same parameters, the LoA analysis showed that 95% of all measurement differences between insole and force plate measurements were less than 12%, demonstrating high precision of the sensors. However, highly dynamic behaviour of GRF, such as force rate, is not yet sufficiently resolved by the insole devices, which is likely explained by the low sampling rate. 相似文献
This study examined observers' perceptions of nine different types of touch (including a "no touch" control condition) used in cross-sex relationships between coworkers. Results showed that face touch sends particularly strong relational and emotional messages. A soft touch in the cheek area of the face was seen as signaling more affection, attraction, flirtation, and love than the other types of touch. Face touch was also rated as the most inappropriate and sexually harassing of the nine types of touch examined. Arm around the waist was also rated as showing relatively high levels of attraction and flirtation, as well as inappropriateness and harassment. No touch and handshaking conveyed the most formality. Observers rated women as more affectionate, trusting, happy, and composed than men across the touch conditions. Men, however, were judged to be more attracted to their cross-sex partners than were women. These and other findings are discussed to shed light on the multiple interpretations of touch within the context of relationships between cross-sex coworkers. 相似文献
