This study investigated the basic cognitive skills soldiers must possess before entering the Army, skills that are needed for successful completion of entry-level training. Judgments of 126 instructors from 25 military occupational specialties were obtained on 129 candidate skills, which resulted in the identification of 55 basic skills. Factor analysis of these 55 skill items resulted in 11 interpretable factors. Mean scores on the factors were compared across factors and across Army training schools. The results of the study suggest that, for all occupational specialties studied, skills related to the learning process are as crucial as traditional academic skills for successful training course completion. These results have important implications for training for the Army as well as for industry. 相似文献

Recent privacy-related incidents of mobile services have shown that app stores and providers face the challenge of mobile users’ information privacy concerns, which can prevent users from installing mobile apps or induce them to uninstall an app. In this paper, we investigate the role of app permission requests and compare the impact on privacy concerns with other antecedents of information privacy concerns, i.e., prior privacy experience, computer anxiety, and perceived control. To test these effects empirically, we conducted an online survey with 775 participants. Results of our structural equation modeling show that prior privacy experience, computer anxiety, and perceived control have significant effects on privacy concerns. However, concerns for app permission requests have approximately twice as much predictive value than the other factors put together to explain mobile users’ overall information privacy concerns. We expect that our findings can provide a theoretical contribution for future mobile privacy research as well as practical implications for app stores and providers. 相似文献

Pattern recognition development was studied in high and low ability preschool, kindergarten, and first-grade youngsters. Pattern recognition was assessed by the administration of 96 pattern tasks which measured the ability of a youngster to find: (a) duplicate patterns and elements to a model; (b) the opposite pattern to a model; and (c) duplicate patterns but different elements than in the model. Aside from main effects for grade level, ability level, and pattern task, a significant three-way interaction was noted. This interaction was analyzed in terms of its component simple effects. The implication of these simple interaction effects for Piagetian theory and educational practice were discussed. 相似文献

Interest in the quality of published research is evident across the range of disciplines including education. Several comprehensive studies either sponsored or published by the American Educational Research Association attest to this fact. In the sciences, citation analysis is attracting interest as a methodology for assessing research. The procedure has both theoretical and practical promise. The present study considers an overlooked source of information, reprint requesting, as a possible adjunct to citation analysis. The study stems from the questionnaire responses of 24 reprint requestors for an article by the authors. Requestor characteristics, motives, and reprint uses are considered. Implications for further research are advanced. 相似文献

Tape recordings were made of six white and six black ninth-grade northern boys speaking identically worded answers to typical school questions. Black students were given significantly higher grades than white students by 56 white and 50 black southern teachers. Black teachers gave significantly higher grades than white teachers, but no significant interaction was found between students' and teachers' ethnic group. The study is a partial replication of a previous study in which it was found that black students were given significantly lower grades than white students by northern white teachers. 相似文献

现今我国正在大力推行素质教育,而学校推行素质教育的最直接的实施者是教师,但目前有部分教师自身素质存在滞后现象,他们的思想、学识和能力直接影响了教育素质的效果,因而教师自身素质的培养必须提到日程上来。 相似文献

Self-worth theorists have claimed that students of lower ability may reduce effort in likely failure situations to avoid the attribution of poor performance to their own incompetence. The likely success of mastery learning, an instructional technique stressing student persistence, has been questioned because of this phenomenon. Several studies which examined the hypothesized relationship between achievement, effort, and perceived ability within a mastery context were conducted. In none of the studies did it appear that students reduced effort because of the threat of failure or that expending effort led to lower estimates of ability. In fact, students expending effort rated their ability as having a more positive influence on performance than less persistent students. It is argued that mastery learning, like some achievement change programs, encourages students to attribute their performance to their level of effort. 相似文献
