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

As part of an overall evaluation of the Global Learning and Observations to Benefit the Environment, (GLOBE) program, we designed a Web-based assessment environment to measure students' environmental awareness and data analysis skill. It was expected that students who were identified as high implementers in the GLOBE program would outperform low implementers in their ability to construct environmental inferences and the degree to which they could analyze environmental data. Seven high and middle school classrooms were identified as either high or low GLOBE implementers depending on the amount of atmospheric data they had collected during the year. Within each classroom students were assigned into smaller learning groups of three students per group. A total of 32 groups participated in this study. Analysis of students' responses to the tasks revealed that the students differed in their performance. Overall, the results showed that students in the high implementing classrooms were more likely to construct higher-level environmental inferences than students in the low implementing classes. Contrary to expectations, middle school students were more likely than high school students to solve the data analysis problem correctly. However, upon further analyses, high school students constructed more data graphs and were more skilled in providing correct evidence to support their decision making than were middle school students in GLOBE. This study confirms the viability of using technology-based assessments for measuring students' environmental awareness and data analysis. 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

Many researchers who are interested in studying students’ online self-regulated learning (SRL) have heavily relied on self-reported surveys. Data mining is an alternative technique that can be used to discover students’ SRL patterns from large data logs saved on a course management system. The purpose of this study was to identify students’ online SRL patterns with the use of data mining techniques. We examined both self-reported self-regulation surveys and log files to predict online students’ achievements and found using log files was more powerful in predicting students’ achievements in an online course than self-reported survey data. Discussions to enhance teaching and learning practices with the use of data mining are provided. 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

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
