The determinants of fourth, fifth, sixth, seventh, and eighth graders' intentions to perform science learning activities were investigated. Ajzen and Fishbein's theory of reasoned action was used to assess students (n = 254) on their laboratory and nonlaboratory behavioral intentions, which required using the two determinants included in the theory (attitude toward the behavior and subjective norm) as well as five external variables identified by the researcher. The five external variables were gender, grade, race/ethnicity, socioeconomic status as determined by the range of the family's annual income, and attitude toward science. Two models were tested. The first model included the two determinants as predictor variables and behavioral intention as the criterion. The second model involved the analysis of the two determinants as they were considered in subgroups according to the five external variables. This model also included interaction terms. For laboratory learning activities, the two determinants (attitude toward behavior and subjective norm) were found to contribute collectively to the prediction of behavioral intention, accounting for almost a fourth of the variance. For nonlaboratory learning activities, the two determinants accounted for over a fourth of the variance in behavioral intention. Testing of the second model revealed that for both laboratory and nonlaboratory behavioral intentions, no interaction terms were significant. The results of post hoc tests on significant predictors of behavioral intentions for laboratory and nonlaboratory activities are reported. Implications of this study on future research are also discussed. © 1999 John Wiley & Sons, Inc. J Res Sci Teach 36: 455–473, 1999 相似文献

Many forms of bias have been identified in higher education research, and in educational and social research in general. This article identifies a further form of bias, positivity bias, and places it in this broader context. Positivity bias is the tendency, in some forms of published higher education research, to only or chiefly report examples of initiatives or innovations that worked and received positive evaluations. Empirical evidence of positivity bias, in the form of an analysis of a sample of published articles from selected higher education journals, is presented and discussed. Suggestions as to the causes of positivity bias and how it might be handled are presented. 相似文献
