A computer program was written in PCPilot to teach a unit in basic concepts in experimental design. The graphics-based program includes both tutorials and simulations. The students who used the program had significantly higher test scores than those in another class who did not; they reported that they enjoyed learning to use the program.  相似文献

THE "FRESHMAN 15"Facts and Fantasies About Weight Gain in College Women   总被引:1,自引:0,他引:1  
This research tested the hypothesis that the "freshman 15" may be more fantasy than fact. The "freshman 15" refers to the belief that college students, particularly women, gain an average of 15 pounds during their first year of college. Female college students were weighed during their first month at college and again 6 months later. They also completed measures of self-esteem, body image, locus of control, and self-monitoring. Findings indicated that the majority of women remained the same weight during the first 6 months of college. A favorable body image was related to less weight loss among those who lost weight, but none of the other characteristics were related to weight change.  相似文献

The convergent validity of the two most frequently used methods for assessing violent offending in juveniles (i.e., selfreports and arrests) was evaluated. Participants were 87 serious juvenile offenders and their maternal figures, primarily from disadvantaged families. Validation measures tapped established behavioral, family, and peer correlates of delinquency. Results failed to support the ability of either arrests for violent crimes or selfreported violent offenses to index violent criminal behavior accurately. Several methodological features of the study support our hypothesis that the findings were not spurious. Procedural and conceptual implications of the findings are discussed.The Family and Neighborhood Services Project was funded by Grant 2H87MH43557-04 to the South Carolina Department of Mental Health from the National Institute of Mental Health. The authors extend their most sincere appreciation to Commissioner Joseph Bevilacqua, Commissioner Richard McLawhorn, Joe James, Dale Chandler, Madeline Blackwell, Kristen Rowden, Pam King, Nancy King, Nancy Yue, and Jerry DeLoye.  相似文献

This paper presents the results of a study testing components of the Triandis model of choice to predict intention to obtain screening mammography in the next 2 years. A questionnaire was developed to measure the theoretical components of this model. Analysis was based on 2,521 women, 50 to 65 years old, who received primary care from 1 of 28 participating primary care group practices. Based on the four theoretical components of intention described in the Triandis model-social influence, affect, consequence, and barriers-a set of structural equation models was explored. The sample was split into two equal subsamples: one sample used for model exploration and one used for model confirmation. Results showed that the original intention model was not supported. Instead, the model that best fit the data, and upheld it in the subsample used for model confirmation, was a model in which habit and intention were strongly related. The strongest predictors of habit were barriers and consequences; the strongest predictors of intention were social influences and barriers.  相似文献

College courses are generally developed because of current fashion in the field and/or student and faculty interest in some topic without reference to departmental or programmatic goals. Current calls and needs for accountability in higher education demand a more organized approach. A computer program, ToolBook 1.53, which provides information to the instructor about systematic development of courses and assessment of student outcomes, is described. The program supports the construction of outcome-oriented learning objectives and corresponding assessment techniques. Instructors who used this program to learn about how to construct such objectives showed an increase in knowledge and evaluated the program positively. Using the information provided in this program leads to an integrated approach to course design and development in which course objectives are linked to the college mission statement through departmental or program objectives.  相似文献

The optimal stimulation theory proposes that hyperactive children are less tolerant of lower levels of arousal than nonhyperactive children and should thus derive greater gains from stimulation added to repetitive copying tasks than do comparisons. To test this hypothesis, 16 adolescents, rating high on attention and behavior problems, were matched on the basis of age and poor handwriting performance to 16 controls. Matched pairs were randomly assigned to treatment order (high-stimulation colored letters followed in 2 weeks by low-stimulation black letters or the reverse order) and to level of information (color added to difficult letter parts or added to randomly selected letters), counterbalanced for treatment order and level of information within each order. Errors and activity were subjected to a mixed-design analysis of covariance, with IQ the covariate. The major findings indicated that attention-problem adolescents performed better with high-stimulation task stimuli than with low, relative to the opposite performance pattern of controls. Different responding was significant for experimental but not for control children.This research was supported by National Institute of Mental Health Grant MH32282 to the first author.  相似文献

This research examined beliefs about the utility of environmental, semantic, and phonological cues for remembering, as these beliefs are related to feelings of self-esteem, assertiveness, and locus of control. We proposed different types of relationships between self-esteem (and assertiveness) and metamemory for two group of college students, based on their differential experiences with distinctive memory failures. For students who were familiar with their current environment, self-esteem was positively related to confidence in having a good memory. It was only for newcomers—students who had recently moved to a new environment—that beliefs about the benefits of environmental cues were positively related to self-esteem and assertiveness. These results suggested that if newcomers were less aware of the utility of environmental cues, they were more likely to attribute their memory failures to their own inadequacies. We also obtained evidence that subjects with an internal locus of control were more knowledgeable regarding the utility of environmental cues than were externally oriented subjects.  相似文献
