This paper addresses the adult educator's responsibility to establish an emotionally safe learning environment. Such a climate enables students to address constructively the fears they bring to the learning event. This empowers the learner to risk change-the goal of adult education. The research of Maslow, Rogers, Knowles, and Freire supports an atmosphere of mutual respect as the key to adult learning. Trainers/Teachers of adults were interviewed to identify the kinds of fears that adults bring to the learning event. This paper explores the attitudes and techniques used by the facilitator to create an atmosphere of respect.  相似文献

The authors examined second grade reading accuracy and fluency and their associations via letter knowledge to phonological and language predictors assessed at 3.5, 4.5, and 5.5 years in children in the Jyv?skyl? Longitudinal Study of Dyslexia. Structural equation modeling showed that a developmentally highly stable factor (early phonological and language processing [EPLP]) behind key dyslexia predictors (i.e., phonological awareness, short-term memory, rapid naming, vocabulary, and pseudoword repetition) could already be identified at 3.5 years. EPLP was significantly associated with reading and spelling accuracy and by age with letter knowledge. However, EPLP had only a minor link with reading fluency, which was additionally explained by early letter knowledge. The results show that reading accuracy is well predicted by early phonological and language skills. Variation in fluent reading skills is not well explained by early skills, suggesting factors other than phonological core skills. Future research is suggested to explore the factors behind the development of fast and accurate decoding skills.  相似文献

This study examines a model of college choice by parents on behalf of their eighth-grade children. A sample of 931 Illinois parents nominated 154 identifiable institutions in a 1986 survey. Multivariate multiple regression is used to predict preferred institutional characteristics, including selectivity, highest degree offering, proximity, enrollment, and tuition. Results indicate that socioeconomic, familial, and college planning characteristics explain 35 percent of the variance in selectivity of colleges in the choice sets, with lesser (but significant) percentages of explained variance for the other institutional characteristics. These parental college nominations parallel previously reported matriculation behaviors.  相似文献

Rats were exposed twice in a rotated sequence to a series of six mazes, consisting of hexagonal alleys, balanced for different alley length and structural complexity. Locomotor activity increased with alley length and decreased with structural complexity of the mazes. Locomotion became less stereotyped with increased experience, showing an increasing number of turns, less constant velocity, loss of the initial preference for outward leading alleys and weakening of the forward tendency at reentry from side alleys into hexagonal alleys. In contrast to these qualitative changes of locomotion, the amount of activity remained almost unchanged throughout the experiment. The results suggest that these increases in locomotion complexity depend upon complex interactions between experience and stimulus content of the mazes.  相似文献

This study examines a pre‐school screening survey battery with an aim to validate it in terms of predicting school performance. Subjects participating in the screening were tested at the end of their first year at school. Analysis of the data, using a canonical correlation procedure, suggested elimination of a number of test items ‐‐ age, sex, age of walking, socio‐economic rating, Draw‐a‐Man Test, balance and posture, body image, perceptual motor match, height and weight. Measures of general ability, visual discrimination, visual reception, general development, receptive language, language concepts and positional concepts were the best predictors of school performance.  相似文献
