学分制作为一种教学管理制度,已被各高校普遍采用。但在实施过程中存在着学年制观念根深蒂固、高校办学自主权较小、教学资源难以满足要求、选课体系不够完善、学生个人因素、教育结构与经济结构不协调等问题。应采取转变教育观念、落实和扩大学校办学自主权、高校"联姻",学生跨校修读课程、学生自主选择导师和课程、校企合作等措施完善学分制改革。 相似文献

附加数学(Additional Mathematics)是香港地区的特色数学课程之一,是在高中开设的需修读两年(中四与中五)的选修课程,主要面向在兴趣与能力上均达到一定水平,并将会在中六、中七年级修读理科或纯粹数学课程的学生,修读本课程的学生需要同时修读《中学课程纲要:数学科(中一至中五)》(1999年)规定的必修课程.为了顺应必修数学课程发展的要求,降低在中四、中五(相当于高一、高二)阶段开设的附加数学课程难度,并减低本课程与中六、中七数学课程重叠的影响,香港课程发展议会在修订原有附加数学课程纲要(1992年)的基础上,于2001年正式颁布《附加数学课程指引(中四至中五)》,并已于2002 相似文献

We use three data sources to build a rationale for why intensive interventions are necessary for students with pervasive reading disabilities: current data on the performance of students with disabilities on reading achievement measures over time, observation studies on students with reading disabilities in general and special education classrooms, and findings from intensive intervention studies for students with reading disabilities. Results of these data sources indicate that students with disabilities are not making progress in reading at the same rate as students without disabilities, reading instruction for students with reading disabilities is comprised of excessive amounts of low level tasks, and findings from intensive intervention studies suggest positive impacts for students with reading disabilities. We argue that students with reading disabilities require ongoing intensive interventions that are likely to require schools to change the contexts and practices for these students. 相似文献

Developing students' ability to interpret the vast amount of quantitative data they encounter on a daily basis has become a major task for today's educators. However, very little attention has been given to students' strategies of analyzing multivariate data. This study investigated how students interpret and analyze multivariate data organized in tables and the nature of external visual displays that they tend to create and use for this purpose. Ten middle school students were asked to think aloud while solving five problems demanding an analysis of data organized in tables. The students were then interviewed. Results indicated that (1) students based their conclusions on only part of the data; (2) students did not use either efficient or sufficient visual representations; (3) students did not apply mathematical operations efficiently; and (4) students referred to or built a context to the problem. The results of the current research may assist educators to design efficient curricula while being aware of and taking into account (1) students' difficulties in employing previously learned mathematical devices to analyze data, (2) students' skills in choosing appropriate and efficient visual representations to present and interpret the data, and (3) strategies employed by students in analyzing multivariate data. 相似文献

在分析化学实验中,评价学生的实验成绩,传统的方法是用教师预先所做的几个测量数据作为标准,这样给学生的数据评分是不完全合理的。文章以学生测定水的硬度实验为例,应用Matlab软件编制程序对学生的数据进行分析,能快速、简便、直观地绘制出相应学生实验数据分布的图形,这样就能客观、公正地评价学生的实验数据。 相似文献

In the context of an afterschool program in which students explore relatively large authentic datasets, we investigated how 11- to 14-year old students worked with categorical variables. During the program, students learned to use the Common Online Data Analysis Platform (CODAP), a statistical analysis platform specifically designed for middle and high school students, to create and interpret graphs. Following the program, we conducted individual clinical interviews, during which students used CODAP to answer questions about relationships between variables. Here, we describe how students engaged in exploratory data analysis that involved looking at relationships between two categorical variables. Students worked from data in table form and created “contingency graphs,” a variant of contingency tables, which they used to analyze and draw insights from the data. Our research identified four strategies that students used to examine the data in order to explore patterns, make comparisons, and answer questions with the data. 相似文献

Technology has become affordable and available for science teachers of all grade levels. This study presents the results of collecting attitudinal data from over 240 ninth grade physical science students prior to the integration of technology into their science curriculum. The data were evaluated utilizing a probabilistic model, which corrects for the nonlinearity of rating scale responses. Results indicate that surveyed students, on average, were supportive of the integration of a wide range of technology into their classroom. Although students were generally positive, they were statistically more supportive of activities that involved the sending of electronic messages to other students when a comparison was made to their attitudes toward the collecting of data with computer probes. The results suggest that physical science teachers may want to initiate the integration of technology into classes by first requiring students to use electronic mail to share data collected without the aid of a computer. This activity could, in turn, be followed by labs that require the collecting of data with computer probes and subsequent sharing of that data with other students through electronic mail. 相似文献

Student absence in South Australian schools 总被引：1，自引：0，他引：1
Sheldon Rothman 《The Australian Educational Researcher》2002,29(1):69-91
Students who are frequently absent from school (‘non-attenders’) are considered to be ‘at risk’. State education departments have recently begun to improve their collection of student absence data, often to contribute to the development of performance standards for schools. This paper presents a summary of data from the Term 2 collection in South Australian government schools. The data were combined with student information, which allowed examination and comparison of attendance patterns for different groups of students. The author provides details about which students were absent in those years, the frequency of students’ absences, which students had no absences, and the stated reasons for students’ absences. The author recommends that no single attendance standard can be set for schools, based on the differential targets shown for different groups of students. 相似文献

Grades are important for admission of students in most higher education programs. Analyzing admission and student performance data at a major Norwegian business school, we find that the grading practice of teachers at regional colleges sending students to the school is affected by the average performance of the students being graded. Teachers at colleges recruiting good students from upper secondary school tend to be strict in their grading practice, while teachers at colleges recruiting less good students tend to follow a lenient practice. This has implications for the interpretation of grades and hence for optimal admission procedures. We develop a methodology to assess the consequences of differential grading standards. Approximately 10% of the students in our data are admitted at the expense of more competent students. We demonstrate costs for the school admitting the wrong students and in particular for the rejected students. 相似文献
