为培养科学素养而培训启蒙者——柳州市小学科学教师专业化发展现状调查报告

一、研究目的《小学科学课程标准》指出:"小学科学课程是以培养科学素养为宗旨的科学启蒙课程。"小学科学教师作为小学生科学学习的启蒙者、科学知识的传播者、科学方法的引导者、科学精神的培养者,其专业化程度的高低直接影响着小学科学教学质量和小学生的科学素养的养成。为了了解柳州市小学科学教师队伍专业化水平,制定下一步教师培训计划,2006年8月,我们对柳州市小学科学教师的专业化状况进行了调查。     

高中物理教学中的美育初探

一、美在物理学中的表现美普遍存在于物质和精神世界中。物理学是研究物质世界的结构、运动及其变化规律的科学,是自然科学的重要组成部分,研究范围大到宇宙天体,小到微观粒子。一句话,是反映我们身边这个世界的科学。物理之美表现在物理现象、科学原理和研究精神等几方面。     

The AVOM: A model-derived,age-limited,and modality-related test of intellectual functioning

The current status of intellectual assessment is reviewed. Traditional psychometric techniques are criticized for yielding only a single score that purports to measure the individual's intellectual ability. Such a unified score gives no indication of what specific deficit is present, nor does it suggest a strategy for remediation. The AVOM Test is presented as a potentially useful device. This experimental test measures performance in two input channels, auditory and visual, and two output channels, oral and manual. AVOM was administered to over 200 elementary school students. Scores increased with age, and the other results were supportive of the potential utility of the device.

Social and Cognitive Outcomes: A Comparison of Contexts of Learning

This study determines effects of social learning contexts (classroom, school and boards) on social and cognitive outcomes of primary school pupils. Central to this research are the differential effects of attending private and public schools for pupils' math achievement and sense of well-being at school. The relationship between pupil backgrounds, sector, characteristics of classrooms, schools and governing bodies on the one hand and pupil outcomes, on the other, have been analyzed using multilevel analysis (VARCL). The sample consisted of 103 schools and 2023 pupils (grade 8, age 11). After controlling for socioeconomic backgrounds, the results show that indicators of cognitive and social effectiveness are mainly climate factors. Basic elements of cognitive school effectiveness (math) seem counter-productive with respect to pupils' sense of well-being at school.     

Within‐High‐School Versus Across‐High‐School Scaling of Admissions Assessments: Implications for Validity and Diversity Effects

Previous research has established that SAT scores and high school grade point average (HSGPA) differ in their predictive power and in the size of mean differences across racial/ethnic groups. However, the SAT is scaled nationally across all test takers while HSGPA is scaled locally within a school. In this study, the researchers propose that this difference in how SAT scores and HSGPA are scaled partially explains differences in validity and subgroup differences. Using a large data set consisting of 170,390 students each of whom matriculated at one of 114 separate colleges, the researchers find that awarding SAT scores by ranking SAT within a high school generally results in substantial reduction in the size of subgroup mean differences for this predictor. However, validity for predicting first‐year GPA is also reduced by a small amount. Conversely, placing HSGPA onto a nationally normed metric through the use of multiple regression procedures results in a moderate increase in the size of subgroup mean differences, while also producing a small increase in validity. Taken together, these findings suggest that differences in predictor scaling can partially explain differences in the size of subgroup mean differences between HSGPA and SAT scores and have implications for predictive power.
