This paper aims to draw the attention of teachers of basic university physics courses towards students' problems concerning the interpretation of the symbolic language used in the discipline. Specific difficulties found in the first course of physics, related to different kinds of statements expressed in mathematical language, are pointed out and analysed, and some suggestions are made to cope with them during instruction. It could be concluded that teachers may need only to reflect and comment on the virtues of making explicit the semantic and syntactic aspects of formal languages as they teach physics. 相似文献

A number of studies have identified correlations between children’s stereotypes of scientists, their science identities, and interest or persistence in science, technology, engineering, and mathematics. Yet relatively few studies have examined scientist stereotypes among college students, and the literature regarding these issues in predominantly nonwhite and 2-yr college settings is especially sparse. We piloted an easy-to-analyze qualitative survey of scientist stereotypes in a biology class at a diverse, 2-yr, Asian American and Native American Pacific Islander–Serving Institution. We examined the reliability and validity of the survey, and characterized students’ comments with reference to previous research on stereotypes. Positive scientist stereotypes were relatively common in our sample, and negative stereotypes were rare. Negative stereotypes appeared to be concentrated within certain demographic groups. We found that students identifying nonstereotypical images of scientists at the start of class had higher rates of success in the course than their counterparts. Finally, evidence suggested many students lacked knowledge of actual scientists, such that they had few real-world reference points to inform their stereotypes of scientists. This study augments the scant literature regarding scientist stereotypes in diverse college settings and provides insights for future efforts to address stereotype threat and science identity. 相似文献

AbstractThe Electronic Cataloging in Publication (ECIP) Cataloging Partnership Program began in 2004. It is a collaboration between the Library of Congress (LC) Cataloging in Publication (CIP) Program, publishers, and libraries across the United States. System set-up for the program proved challenging for library partners. A survey was conducted during February 8–March 6, 2018 to learn about ECIP partners’ ECIP set-up experience. The findings show that communication and training documentation are two key elements for the program to be effective and successful. The survey results helped the LC CIP program develop a new and improved ECIP system. 相似文献
