This paper discusses students’ use of anthropomorphic language in science, and in particular calls upon some examples from research into student understanding of chemical bonding. It is argued that anthropomorphic language is common amongst scientists as well as science students. A simple classification of such instances is suggested to distinguish between those examples that are useful in aiding communication and understanding, and those which merely stand in place of such understanding.  相似文献

In this paper, we identify appropriate statistical methods for analysing categorical differences in discrete variables or 'performance indicators' resulting from performance analysis. The random mechanisms associated with discrete events do not follow a normal distribution; that is, the normal distribution is a continuous not a discrete probability distribution. We propose appropriate statistical methods based on two key discrete probability distributions, the Poisson and binomial distributions. Two approaches are proposed and compared using examples from notational analysis. The first approach is based on the classic chi-square test of significance (both the goodness-of-fit test and the test of independence). The second approach adopts a more contemporary method based on log-linear and logit models fitted using the statistical software GLIM. Provided relatively simple one-way and two-way comparisons in categorical data are required, both of these approaches result in very similar conclusions. However, as soon as more complex models or higher-order comparisons are required, the approach based on log-linear and logit models is shown to be more effective. Indeed, when investigating those factors and categorical differences associated with binomial or binary response variables, such as the proportion of winners when attempting decisive shots in squash or the proportion of goals scored from all shots in association football, logit models become the only realistic method available. By applying log-linear and logit models to discrete events resulting from notational analysis, greater insight into the underlying mechanisms associated with sport performance can be achieved.  相似文献

Using three stratified random samples of thirty-two teachers each from grades 2 through 5, a 3-group posttest-only control group research design was employed to determine the effectiveness of an in-service program utilizing simulation techniques on teacher awareness of pupils’ instructional reading levels. Pupils were selected randomly from each teacher’s classroom. Differences between the grade level of pupils’ readers and their performance on McCracken’s Standard Reading Inventory constituted the measure of teacher awareness. The importance of teachers’ grade level assignments and the time of year when this in-service training is conducted were also evaluated.

Findings indicated that this in-service program is effective only when conducted before school begins. There was a significant difference in teacher awareness among grade levels but a contravertible one between primary and intermediate levels.  相似文献
