字理识字是依据汉字的构字规律,借助汉字形、音、义的关系进行识字教学的方法,也就是通过对象形、指事、会意、形声等造字法的分析,运用直观、联想等手段识记字形,以达到识字的目的。在识字教学中,如果我们能恰当地利用汉字构形的理据,可以帮助学生深刻地理解汉字的构形原理从而大量地消灭错别字,提高识字教学的效率。 相似文献

Tested the hypothesis that providing immediate feedback to homeowners concerning their daily rate of electricity usage would be effective in reducing electricity consumption. In the 29 physically identical 3-bedroom homes used in the study, central air conditioning was the largest single source of electricity usage during the summer. Accordingly, it was possible to predict the household's expected electricity consumption in terms of the average daily outdoor temperature. Feedback was expressed as a percentage of actual consumption over predicted consumption, and it was displayed to the homeowners 4 times/wk for approximately 1 mo. Results confirm the hypothesis. Before feedback began, the feedback and control groups were consuming electricity at approximately equal rates. During the feedback period, the feedback group used 10.5% less electricity. The effectiveness of the feedback procedure is discussed in terms of its cuing, motivational, and commitment functions. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Assigned 129 participant households in Texas during the summer to 1 of 5 experimental conditions: A high monetary rebate condition in which Ss received conservation information, weekly written feedback on their electricity use, and monetary rebates amounting to a 240% price change in electricity; a low monetary rebate condition with the same structure as the high rebates except payments amounted to a 50% price change; a weekly feedback condition in which Ss also received information but no rebates; an information condition; and a control condition. The dependent measure was percentage reduction in electricity use based on actual weekly meter readings by the research staff. Only the high rebate condition significantly curtailed electricity use by about 12% over the course of the study. Elasticity estimates suggested limited responsiveness in electricity consumption to price changes. Questionnaire data showed a pattern in which actual reduction in electricity was associated with planning a conservation program, attending to feedback, and modifying air conditioning use.
