ABSTRACT: A simple laboratory experiment, based on the Maillard reaction, served as a project in Introductory Statistics for undergraduates in Food Science and Technology. By using the principles of randomization and replication and reflecting on the sources of variation in the experimental data, students reinforced the statistical concepts and techniques introduced to them in lectures before the experiment. The experiment was run simultaneously by several student groups, using the same materials. Comparing the results of their analyses of variance, students became aware of the difference between P values and significance levels in making statistical decisions. In the experiment, the complete randomized design was applied; however, it is easy to adjust the experiment to teach students simple regression and randomized block designs. 相似文献

Comparative studies of attitudes in different countries have resulted in the claim that parents in the USA and England tend to have unrealistically positive views of their children's schools and academic performance. Low expectations, together with a belief in the importance of natural ability, it has been argued, lead to low standards and reduce striving to succeed. The present study builds upon earlier investigations of children's attitudes, beliefs and behaviours in Sunderland, Eastern Kentucky and St Petersburg by surveying parental perspectives. Findings from these three regions reinforce earlier findings about English and American complacency and the more demanding nature of the Russian context. In line with our earlier studies, and contrary to the suggestion of a number of writers, an emphasis upon effort, rather than ability, was a strong feature of the English and American responses, although it is pointed out that such beliefs may not actually result in high work rates. The paper concludes by suggesting that the important role of parents in instilling important attitudes and behaviours in their children is undermined by the current emphasis upon schools as fundamentally responsible for ensuring high levels of achievement. 相似文献

The ability to understand and evaluate news reporting of science is often cited as an attribute of a scientifically literate person. This work reports on an attempt to develop such attributes in a group of 19 student‐teachers. They were introduced to a review technique designed to help them evaluate newspaper representation of science and engage more effectively in a course dealing with biotechnology and associated socio‐scientific issues. The work they produced was examined for a range of evidence, and this showed that they were able to comment effectively on issues such as the newsworthiness of stories, bias in reporting, and the portrayal of science and scientists. Questionnaire responses indicated that the technique helped them to think about the media reporting of science in ways that were new to them. They believed school‐age students would benefit from a similar technique, and its use in schools is seen as highly desirable. 相似文献

Abstract Learning outcomes for an interactive television‐based distance learning course in introductory high school Japanese were evaluated in three successive years by comparing student achievement in the distance learning course to that in traditional classes. Year‐end achievement tests of listening and written language competency were administered to students in both the distance and face‐to‐face courses. Results in the first two years showed that test scores of students in the distance learning course were higher than those of students in the face‐to‐face classes; however, possible group differences in motivation, general ability, and experience as language learners could not be ruled out as explanations for the difference. Therefore, achievement measures were supplemented in the third year with data on students’ perceived efficacy as Japanese language users, their grades, and their previous foreign language learning experience. The achievement data again showed differences favoring the distance learning group; trends were consistent for students with differing levels of school success and amount of prior language learning experience. Factors that could account for these results are hypothesized and suggestions for future research are proposed. 相似文献
