This article makes the claim that developing ethnographic work through follow-up interviews can add to our understanding of researched phenomena and explores how using concepts from Bourdieu and theories on the social construction of time strengthen the research design and add a stronger longitudinal diachronic element to data analysis. Extending an ethnographic study of learning to teach by interviewing respondents nine years after the study and after the completion of their teacher education course is shown to develop insights around the initial research findings by focusing on the temporal aspects of data. Adopting this methodological approach can develop small-scale qualitative work and contribute to an accumulation of research findings to avoid simply revisiting familiar research ground. 相似文献

Anatomy, has in history, been linked to helpful ways to remember structures, branches of nerves, structures passing through foramina, etc. Scalp is even a mnemonic in itself (S kin, C onnective tissue, A poneurosis, L oose areolar tissue, P ericranium). There has been concern by some educators that using mnemonics or rhymes promotes a surface approach to learning and is unhelpful in establishing long-term and meaningful deep learning. This article argues that mnemonics and rhyme can be used, in the appropriate way, at the right time, by students as an important learning strategy. That strategy can help lay a foundation of knowledge to be developed and later built upon, or simply recall information more easily. Mnemonics, like all information that is to be recalled, is consolidated by rehearsal. In examining the neuroanatomy of learning theories, it is therefore possible to suggest that when students begin to learn an area of anatomy, such as the cranial nerves, using a mnemonic or rhyme, it can help students remember the names and facilitate the engagement of the working memory processes assisting the student to build a construct for subsequent deeper layers of knowledge. Modern approaches to anatomy education involve a myriad of learning opportunities, but educators must assess the value of each one before recommending them to students. It appears that using mnemonics and rhyme is as valid today as it has been for centuries. 相似文献

Content analyses of program variables and verbal content features were conducted on Saturday morning children's programming. Three tools were developed for the study which assessed general context features, supportive and defensive language, and other verbal language features. The results describe the verbal climate of Saturday morning programs. 相似文献

Previous studies analysing electromyograms (EMGs) from indwelling electrodes have indicated that fast-twitch motor units are selectively recruited for low-intensity eccentric contractions. The aim of this study was to compare the frequency content of surface EMGs from quadriceps muscles during eccentric and concentric contractions at various contraction intensities. Electromyograms were recorded from the rectus femoris, vastus lateralis and vastus medialis muscles of 10 men during isokinetic (1.05 rad x s(-1)) eccentric and concentric knee extension contractions at 25%, 50%, 75% and 100% of maximal voluntary contraction (MVC) for each contraction mode. Additionally, isometric contractions (70 degrees) were performed at each intensity. The mean frequency and root mean square (RMS) of the surface EMG were computed. Mean frequency was higher for eccentric than concentric contractions at 25% (P < 0.01), 50% (P < 0.01) and 75% (P < 0.05) but not at 100% MVC. It increased with increasing contraction intensity for isometric (P < 0.001) and concentric (P < 0.01) contractions but not for eccentric contractions (P = 0.27). The EMG amplitude (RMS) increased with increasing contraction intensity similarly in each contraction mode (P < 0.0001). Higher mean frequencies for eccentric than concentric contractions at submaximal contraction intensities is consistent with more fast-twitch motor units being active during eccentric contractions. 相似文献
