The purpose of the present study was to investigate instructional methods appropriate for developing problem solving skills (PSS) in a paramedical course. Three instructional methods were compared: Frontal Lecture Strategies (FLS), Mastery Learning Strategies (MLS) and Experiential Mastery Learning Strategies (EMLS) in which feedback corrective procedures were embedded within experiential learning situations. Results showed that FLS produced the highest scores on Lower Mental Process subtest while EMLS yielded the highest scores on all measures of problem solving skills. Several implications of this study for future research are suggested and discussed. 相似文献

怪诞美学与小说诗学--论巴赫金的思想与概念体系对当代科学的意义 总被引：2，自引：0，他引：2

解释诗歌象征与小说言外之意、古典审美规范与怪诞审美规范这两对对应范畴 ,可以说明巴赫金的怪诞美学思想与小说理论之间的内在联系。怪诞不是对古典规范的偏离 ,而是与古典规范并存的地位相当又彼此补充的一种规范 ,巴赫金的这一思想为我们探讨历史诗学研究中怪诞小说审美因素的特征问题提供了理论依据。在19世纪与 2 0世纪的非诗歌艺术作品中 ,各种“纯粹的”怪诞形式表现出以下突出特点 :(1)文学的主体形象是以不同意识之间边界的转换为基础建立起来的 ;(2 )统一的和直接的描绘法让位于逆向的描绘法或者被它所取代 ;(3)就小说修辞而言 ,在各种双声性话语的变体中 ,具有“内在对话性”(与“双体性身体”完全类似 )的话语形式占据主导地位 相似文献

We evaluated 32 nonmedicated male adolescents diagnosed with attention-deficit/hyperactivity disorder (ADHD) in childhood, 35 male adolescents similarly diagnosed who were receiving methylphenidate (MPH), and 77 control boys. Both ADHD groups completed self-report questionnaires assessing sleep disturbances; weekday and holiday sleep duration; and symptoms of ADHD, anxiety, and depression. Parents and teachers rated the severity of the participants' ADHD. The control group completed self-report questionnaires assessing sleep disturbances. We found that nonmedicated participants and controls did not differ in the severity of sleep disturbance. In contrast, the medicated participants demonstrated a significantly greater severity of sleep disturbance compared with the nonmedicated participants and reported elevated levels of symptoms of ADHD, anxiety, and depression. Specific analyses showed that depressive symptoms contributed significantly to the degree of sleep disturbance when controlling for ADHD diagnosis and MPH treatment. These findings suggest that among adolescents with ADHD symptoms, the severity of symptoms of depression may contribute to the degree of sleep disturbance in addition to the effect of their primary disorder and MPH treatment. 相似文献

There has been a great deal of discourse in the field of early care and education concerning the experiences, skills, competencies, and education level needed by early childhood teachers to ensure that quality teaching and learning take place in the early years. The purpose of this article is to describe an early childhood teacher preparation program developed by a Child and Family Development Department at a large, urban, state-funded university in the hopes that we can further the discourse on how the field can ensure quality teaching and learning in both ECE and university classrooms. We propose a conceptual model that is built around three key constructs: knowledge, reflection, and practice and describe our approach to preparing early childhood educators. Using qualitative data from student reflections and course syllabi and quantitative data on the experiences and perceptions of graduating seniors, we hope to present promising practices in early childhood teacher education and provide support for our contention that the quality of early childhood teacher education matters. 相似文献

This article summarizes a study of the viewpoints of Bible lecturers in the Kindergarten Education Department while teaching content related to the biblical “other.” The study, by two researchers themselves part of the study population, was conducted according to the qualitative approach and included interviews with participants from a State Education and a State-Religious college. The findings highlight the different points of origin vis-à-vis Bible studies and the search for the connection between the “other” of the Bible, the students’ own world and later, that of the children while indicating discrepancies between declared objectives and the characteristics of the students. 相似文献

This study examined whether children attending Head Start for two years have better developmental outcomes than children attending for one year and whether their families enjoy a more positive family environment. Forty-five children were in the one-year duration group and 29 were in the two-years duration group. The Family Environment Scale (FES), the Child Development Inventory (CDI), and a demographic questionnaire were administered. Results indicated that children’s scores on the CDI did not differ as a function of the length of participation in Head Start. However, families who participated for two years reported an increased intellectual-cultural orientation, and increased active recreational orientation. These families placed greater emphasis on organization, and read more times to their child during the week than families who participated in the program for only one year. 相似文献

We observed and measured the fluid flow that was generated by an artificial cilium. The cilium was composed of superparamagnetic microspheres, in which magnetic dipole moments were induced by an external magnetic field. The interaction between the dipole moments resulted in formation of long chains-cilia, and the same external magnetic field was also used to drive the cilia in a periodic manner. Asymmetric periodic motion of the cilium resulted in generation of fluid flow and net pumping of the surrounding fluid. The flow and pumping performance were closely monitored by introducing small fluorescent tracer particles into the system. By detecting their motion, the fluid flow around an individual cilium was mapped and the flow velocities measured. We confirm that symmetric periodic beating of one cilium results in vortical motion only, whereas asymmetry is required for additional translational motion. We determine the effect of asymmetry on the pumping performance of a cilium, verify the theoretically predicted optimal pumping conditions, and determine the fluid behaviour around a linear array of three neighbouring cilia. In this case, the contributions of neighbouring cilia enhance the maximal flow velocity compared with a single cilium and contribute to a more uniform translational flow above the surface. 相似文献
