Spatial representation and thinking have evolutionary importance for any mobile organism. In addition, they help reasoning in domains that are not obviously spatial, for example, through the use of graphs and diagrams. This article reviews the literature suggesting that mental spatial transformation abilities, while present in some precursory form in infants, toddlers, and preschool children, also undergo considerable development and show important individual differences, which are malleable. These findings provide the basis for thinking about how to promote spatial thinking in preschools, at home, and in children's play. Integrating spatial content into formal and informal instruction could not only improve spatial functioning in general but also reduce differences related to gender and socioeconomic status that may impede full participation in a technological society. 相似文献

In this field experiment, a confederate asked participants to provide a quarter for the confederate to make a telephone call. In the experimental condition, based on the concept of exchange, the confederate offered participants twenty-five pennies for the quarter. The researchers found that there was a significant difference in whether or not the confederate offered the pennies. Eighty-five percent of the participants complied when offered the pennies, while only 35 percent complied without the offer of exchange. Gender was not a factor. Participants over sixty-years-old complied more often than any other age group. Economic status was a factor in that those in the middle range tended to comply more often than those at either the low end or the upper end. 相似文献

Abstract This article describes adapting teacher work sample methodology from the student teaching level to a 4‐week, 25‐hour field experience occurring relatively early in a teacher education program. The goals of the project were twofold: (a) to examine whether an adapted version of the teacher work sample would promote planning and reflection in preservice teachers, and (b) to explore the potential of an adapted teacher work sample as an assessment tool. Adaptations to the original, such as emphasizing formative over summative assessment, are briefly described. Survey and focus group data from a pilot combined with survey data from a semester of full implementation with 270 teacher candidates indicate the teacher work sample is useful for promoting reflection and an understanding of student assessment. The advantages of the teacher work sample are maximized when teacher candidates are engaged in whole class instruction. 相似文献

Over the last decades, teachers have often been identified as ‘key’ players for the improvement of education systems. The successive waves of reform taking place in Latin America since the 1990s have aimed at initial and continuous teacher training. The main changes intended to improve the quality and lengthen the duration of initial teacher training; additionally, the variety of teacher training courses was widened and diversified. This work focuses on the teacher training curricula currently in force for the MERCOSUR member states (Argentina, Brazil, Paraguay and Uruguay). Special attention will be paid to the definitions of the profile that is intended for future teachers, as it is believed that this dimension makes it possible to reveal the different types of expected performance, which will allow us to move towards the dimension of the educational practices. The results obtained from the comparative analysis indicate that the abilities/competences put forth by the four countries are relevant and complementary with each other. Studies of this kind are a step forward in the definition of common policies for MERCOSUR countries aimed at strengthening and articulating teacher training and, specifically, at recognizing teacher qualifications and favouring mobility among countries. 相似文献

Community-based physical activity programs for people with disabilities have barriers that are unique to their program leader qualifications and the population they serve. Moran and Block (2010) argued that there is a need for practical strategies that are easy for communities to implement, maximize resources, and minimize the impact of barriers on each individual. The purpose of this article was to build upon the work of Moran and Block by identifying and systematically addressing barriers to physical activity for people with disabilities in ways that target their sources of self-efficacy. The Empowerment Model is introduced, along with its multi-tiered empowerment continuum of training, support, and programming strands. The goal of the tiered empowerment continuum is to progressively move populations to more independent levels of training, support, and programming. 相似文献

Abstract Individuals with impaired glucose tolerance (IGT) are at greater risk of developing diabetes than in normoglycaemia. The aim of this study was to examine the effects of 12-weeks exercise training in obese humans with IGT. Eleven participants (6 males and 5 females; 49±9 years; mean Body Mass Index (BMI) 32.4 kg · m?2), completed a 12-week brisk walking intervention (30 min per day, five days a week (d · wk?1), at 65% of age-predicted maximal heart rate (HRmax). Anthropometric measurements, dietary intake, pulse wave velocity (PWV, to determine arterial stiffness) and blood pressure (BP) were examined at baseline and post intervention. Fasting blood glucose, glycosylated haemoglobin, insulin, blood lipids, indices of oxidative stress and inflammation (lipid hydroperoxides; superoxide dismutase; multimeric adiponectin concentration and high-sensitivity C-reactive protein) were also determined. Post intervention, PWV (9.08±1.27 m · s?1 vs. 8.39±1.21 m · s?1), systolic BP (145.4±14.5 vs. 135.8±14.9 mmHg), triglycerides (1.52±0.53 mmol . L?1 vs. 1.31±0.54 mmol . L?1), lipid hydroperoxides (1.20±0.47 μM · L?1 vs. 0.79±0.32 μM · L?1) and anthropometric measures decreased significantly (P < 0.05). Moderate intensity exercise training improves upper limb vascular function in obese humans with IGT, possibly by improving triglyceride metabolism, which may subsequently reduce oxidative stress. These changes were independent of multimeric adiponectin modification and alterations in other blood biomarkers. 相似文献
