The purpose of this study was to see whether college students' attitudes toward computers and chemistry would be affected by using CAI materials in a chemistry course, and whether there would be any difference for students of different sex. Students were randomly assigned to experimental and control groups, pre- and posttests were given to both groups, and the data were analyzed using 2-way analysis of covariance. It was found that the attitude of women toward computers was improved by using CAI. No change in attitude toward chemistry was found. 相似文献

We examined the relative contribution of genetic, shared environmental and non-shared environmental factors to the covariance between parental sensitivity and limit-setting observed twice in a longitudinal study using a child-based twin design. Parental sensitivity and parental limit-setting were observed in 236 parents with each of their same-sex toddler twin children (Mage = 3.8 years; 58% monozygotic). Bivariate behavioral genetic models indicated substantial effects of similar shared environmental factors on parental sensitivity and limit-setting and on the overlap within sensitivity and limit-setting across 1 year. Moderate child-driven genetic effects were found for parental limit-setting in year 1 and across 1 year. Genetic child factors contributing to explaining the variance in limit-setting over time were the same, whereas shared environmental factors showed some overlap. 相似文献
