Assessment of the effects of student response systems on student learning and attitudes over a broad range of biology courses 总被引:2,自引:0,他引:2
With the advent of wireless technology, new tools are available that are intended to enhance students' learning and attitudes. To assess the effectiveness of wireless student response systems in the biology curriculum at New Mexico State University, a combined study of student attitudes and performance was undertaken. A survey of students in six biology courses showed that strong majorities of students had favorable overall impressions of the use of student response systems and also thought that the technology improved their interest in the course, attendance, and understanding of course content. Students in lower-division courses had more strongly positive overall impressions than did students in upper-division courses. To assess the effects of the response systems on student learning, the number of in-class questions was varied within each course throughout the semester. Students' performance was compared on exam questions derived from lectures with low, medium, or high numbers of in-class questions. Increased use of the response systems in lecture had a positive influence on students' performance on exam questions across all six biology courses. Students not only have favorable opinions about the use of student response systems, increased use of these systems increases student learning. 相似文献

Three experiments tested human participants on a two-dimensional, computer, landmark-based search task to assess the integration
of independently acquired spatial and temporal relationships. Experiment 1 showed that A-B spatial training followed by B-outcome
spatial training resulted in spatial integration in such a way that A was effectively associated with the outcome. Experiment
2 showed that A-B spatial and temporal training followed by B-outcome spatial and temporal training resulted in integration
that created both spatial and temporal relationships between A and the outcome. Experiment 3 refuted an alternative explanation,
one that is based on decision-making speed, to the temporal-integration strategy that was suggested by Experiment 2. These
results replicate in humans the observations regarding spatial integration made by Sawa, Leising, and Blaisdell (2005) using
a spatial-search task with pigeons, and they extend those observations to temporal integration. 相似文献

Correlational analyses are one of the most popular quantitative methods, yet also one of the mostly frequently misused methods
in social and behavioral research, especially when analyzing ordinal data from Likert or other rating scales. Although several
correlational analysis options have been developed for ordinal data, there seems to be a lack of didactically written literature
illustrating the appropriate use and differences among them. The purpose of this paper is to provide a synthesis of correlational
analysis options when analyzing ordinal data. These options span from the traditional methods, such as Pearson’s r, to more recent developments, such as Bayesian estimation of polychoric correlations. An illustration of these methods utilizing
a contemporary dataset is provided. 相似文献

In order to communicate understanding, students are often required to produce texts which present an explicit, coherent argument. This study examined the extent to which individual differences in undergraduates' topic knowledge and working memory skills were related to their ability to revise texts to better fulfil these goals. Forty-seven students revised texts containing three types of error: language, structure and argument. Topic knowledge was indexed by multiple choice test performance. Verbal short-term and working memory were measured using forward and backward digit recall and reading span. Rates of identification, diagnosis and correction of errors were generally poor. Contrary to expectations neither topic knowledge nor verbal working memory was associated with text revision although significant associations were identified with verbal short-term memory. When revising texts students may focus on the surface features of the text rather than addressing issues of structure and argument. Possible accounts of this tendency are considered. 相似文献

Recent court actions have spurred psychologists to develop improved assessment tools and to utilize diagnostic measures that take into consideration developmental and affective growth patterns of disadvantaged and minority youth. The present study, working through a case vignette, has weighed the possibility that the FM index may serve as a forerunner of abstract thinking, or the capacity to internalize imagery, which, in Rorschach theory, is, with older subjects, best illustrated in M. Findings also suggest that the Z (Organizational Activity) index may not be useful in evaluating intellectual potentials of preschool minority children. Following blind analysis of the Rorschach, replicative data were obtained through a social history and an individually-administered ability test. Data from these sources support the major finding that FM may enable educational diagnosticians to estimate more accurately the intellectual capabilities of some preschool minority and other culturally disadvantaged children. 相似文献
