不走寻常路，理科生PK文科类重点大学     

Roy 《招生考试通讯》2008,(5):11-11

镜头闪回 想去北京上大学,而且一定要上一所重点大学,一直就是我的心愿。为什么呢？原因其实很简单：北京是首都嘛,从小就在课本和电视里了解了很多。后来在一个假期里,爸爸还带我去玩了一趟。什么颐和园、故宫博物馆,北京就是北京,那才叫一个恢宏大气。而且现在考到北京去念书,正好能赶上2008年奥运会。这个机会可是千载难逢啊!  相似文献

Incorporating Uncertainty Into Parallel Analysis for Choosing the Number of Factors via Bayesian Methods     

Roy Levy  Yan Xia  Samuel B. Green 《Educational and psychological measurement》2021,81(3):466

A number of psychometricians have suggested that parallel analysis (PA) tends to yield more accurate results in determining the number of factors in comparison with other statistical methods. Nevertheless, all too often PA can suggest an incorrect number of factors, particularly in statistically unfavorable conditions (e.g., small sample sizes and low factor loadings). Because of this, researchers have recommended using multiple methods to make judgments about the number of factors to extract. Implicit in this recommendation is that, when the number of factors is chosen based on PA, uncertainty nevertheless exists. We propose a Bayesian parallel analysis (B-PA) method to incorporate the uncertainty with decisions about the number of factors. B-PA yields a probability distribution for the various possible numbers of factors. We implement and compare B-PA with a frequentist approach, revised parallel analysis (R-PA), in the contexts of real and simulated data. Results show that B-PA provides relevant information regarding the uncertainty in determining the number of factors, particularly under conditions with small sample sizes, low factor loadings, and less distinguishable factors. Even if the indicated number of factors with the highest probability is incorrect, B-PA can show a sizable probability of retaining the correct number of factors. Interestingly, when the mode of the distribution of the probabilities associated with different numbers of factors was treated as the number of factors to retain, B-PA was somewhat more accurate than R-PA in a majority of the conditions.  相似文献   

Gender and IT in the Household: Evolving Patterns of Internet Use in the United States   总被引：1，自引：0，他引：1  

Ruby Roy Dholakia 《The Information Society》2006,22(4):231-240

Information technology (IT)—computers and related technologies—is the latest technology to enter the household. Like other technologies, gender is a major factor in its adoption and use as well as its perceived usefulness. Unlike prior household technologies, the computer's entry into the household has followed a different pattern. Early statistics revealed a vast gender divide, with men using computers and related technologies much more in the household. More recent statistics show a narrowing of the divide, perhaps even a reversal, particularly in the United States, with women outnumbering men in the access to and use of the Internet. In this article, the role of gender and its relationship with Internet use in the home are reviewed. In addition to overall adoption and access, the review focuses on specific Internet applications and examines the factors that contribute to gender differences in adoption and use of computers and Internet applications in the home.  相似文献

Promoting environmentally sustainable attitudes and behaviour through free‐choice learning experiences: what is the state of the game?     

Roy Ballantyne  Jan Packer 《Environmental Education Research》2005,11(3):281-295

Environmental education, both in and outside of the classroom, aims to facilitate adoption of sustainable practice by both school students and the general public. This paper explores the role of free‐choice learning experiences in this regard. An overview of theoretical approaches underpinning free‐choice learning research is provided, examples are presented of the ways in which informal educational settings can promote environmentally sustainable attitudes and behaviour, and the factors contributing to the effectiveness of these endeavours are discussed. By reviewing research evidence in relation to these issues, the paper identifies the current ‘state of the game’ and areas where new research is needed.  相似文献   

The effects of different feedback strategies using computer-administered multiple-choice questions as instruction     

Roy B. Clariana  Steven M. Ross  Gary R. Morrison 《Educational technology research and development : ETR & D》1991,39(2):5-17

This study investigated the effects of using different forms of computer-based feedback on high school students' learning of science material. The basic design consisted of two conditions of instructional support (text and questions vs. questions only), two testings (immediate vs. retention), five levels of similarity between lesson and posttest questions, and five feedback conditions: knowledge of correct response (KCR), delayed KCR, answer until correct (AUC), questions only (no feedback), and no questions. Results showed significant benefits for feedback over no feedback, with AUC becoming more advantageous and delayed feedback less so as lesson-posttest question similarity decreased. Also, with decreased question similarity and the availability of supporting text, overall feedback effects tended to decrease. The results are discussed in terms of the information processing effects of the different feedback forms, a factor that CBI designers often fail to exploit in planning feedback conditions.This article is based on a doctoral dissertation submitted to the faculty of Memphis State University by the first author.
