ABSTRACTAs Internet usage has proliferated in recent years so have online security threats. Internet users are increasingly susceptible to online security threats. Using a qualitative approach, this study conducted 18 focus groups to examine how three different generations perceive online safety, use coping strategies, and protect themselves online: Silent and GI generation (SGI) (born 1945 or earlier), older Baby Boomers (1946–1954), and Millennials (1977–1992). Results show that although each generation shares a variety of online safety concerns, SGIs and Boomers are more suspicious about online security, have less confidence in their abilities, are uncertain about the effectiveness of protection resources, perform fewer protection behaviors, and are more likely to rely on others’ assistance compared to the Millennial group. Our findings indicate online safety training is needed for all three generations, but especially for older adults. Tailored approaches are suggested to reach different generations. 相似文献

On-line learning is an asynchronous computer-based learning mode that allows learners to learn anytime and anywhere in their own environment using information and communication technology. It can be considered as a way to bridge the digital gap. How a computer novice performs in such virtual and asynchronous learning environments is an interesting issue in human–computer interaction research. This paper presents the results of a study to investigate on-line learning performance and computer anxiety for unemployed adult novices. In this study, we propose a novel idea that integrates the concept of Shannon entropy into a grey relational analysis model. The proposed method was used to measure human information behavior in relation to on-line learning performance and computer anxiety. A total of 115 unemployed adults voluntarily participated in the experimental study. All experimental subjects were divided into groups according to individual differences in gender, age ranges, educational levels, and learning performances. Taking advantage of the grey relation entropy operation, we derived the perceptive correlations among different classified groups in terms of the accessibility of on-line learning and computer anxiety scales, respectively. Through the empirical study, certain on-line learning characteristics were also identified. 相似文献

Correlation is an essential concept in statistics; however, students may hold misconceptions about correlation, even after
receiving instruction. This study aimed to elucidate (1) the misconceptions held by senior high school students about correlation,
using the tool of concept mapping along with interviewing, (2) the possible causes of these misconceptions, and (3) the effectiveness,
advantages, and limitations of the adopted concept mapping using an interviewing technique for identifying student misconceptions.
Twenty-five grade-12 students who had received tuition on correlation were the subjects of this study. Concept mapping through
interviewing was used to collect and analyze data in order to identify the subjects’ misconceptions, and their possible causes.
The major study results are as follows. (1) Seven misconceptions about correlation were detected. Of these seven misconceptions,
five were newly discovered by this study, while the other two are similar to those found by previous studies. Each of the
seven misconceptions was held by 20–68% of the subjects, showing their prevalence and significance. (2) Four major factors
related to the development of misconceptions about correlation were identified: learning materials, language, daily-life experiences,
and existing mathematical concepts. (3) The concept mapping through the interviewing technique adopted in this study was effective
in detecting misconceptions about statistics, especially in revealing new misconceptions, and it was also helpful in exploring
their possible causes. However, tremendous effort and the time consumed are the major limitations of this technique. (4) The
paper concluded by providing some recommendations for researchers and educators. 相似文献

The aim of this study is to explore benchmark corporations in the semiconductor industry based on efficiency. In this study, perspectives of intellectual capital and corporate governance are taken into account for the input data, whereas firm value is considered as the output data. Data envelope analysis (DEA), including CCR and BCC models, is utilized to ensure that the benchmark standards are precisely selected. Based on the result, suggestions for both semiconductor corporations and future research are provided at the end of this article. 相似文献

Overcoming Junior High School Students' Misconceptions About Microscopic Views of Phase Change: A Study of an Analogy Activity 总被引:2,自引:1,他引:1
This study was conducted to examine the effectiveness of an analogy activity, which was designed to overcome junior high students' misconceptions about the microscopic views of phase change. Eighty Taiwanese 8th graders were randomly assigned to either a control group or an experimental group. For the control group, the subjects were instructed through traditional teaching whereas for the experimental group, an analogy activity was conducted on students. This specific analogy activity was presented in the form of role-playing in which students acted as particles and worked together to perform the conditions of phase changes. Through analyzing these students' drawings of the atom arrangements for the three states of some substances, it was found that the students of experimental group, though in many cases, did not perform statistically better than did those of control group in an immediate posttest. The comparisons of a delay test between these two groups indicated that the analogy activity had clearly positive impacts on students' conceptual change on these scientific concepts in terms of long-term observations. 相似文献

University students are regarded as future decision-makers in society and have a high likelihood of becoming opinion-shapers in terms of the environment. Their awareness of the marine environment will therefore have a significant effect upon sustainable marine development. This study examines Taiwanese university students’ marine environmental awareness, focusing on environmental attitudes, understanding of marine and coastal issues, and environmental behavior. A total of 825 valid samples in a questionnaire survey are used for the analysis. Overall, respondents possess a highly positive attitude towards the marine environment and a moderate self-reported level of marine knowledge, but are not actively engaged in environmental protection endeavors, particularly ones involving spending personal income and taking legal or political action. Experience in marine-related activities and marine knowledge are important in fostering marine environmental awareness, particularly in regard to environmental behavior. This study addresses the gap between widespread environmental concerns and low engagement in environmental actions by proposing a multimodal approach: improving marine knowledge and experience in marine-related activities, creating safe recreational spaces at seasides, and reinforcing legal education. This study concludes by highlighting the importance of marine environmental awareness in the development of ocean citizenship as well as the sustainability of the marine environment. 相似文献

The use of peer assessment (PA) as an alternative form of evaluation method is reported to be helpful in learning and is increasingly
being adopted in higher education settings. Through collecting data from 280 university students in Taiwan, a 20-item instrument
was developed to investigate university students’ attitudes toward and perceptions of PA and online PA. Four subscales, Positive
Attitudes, Online Attitudes, Understanding-and-Action, and Negative Attitudes, were extracted and reliabilities were calculated.
Results revealed that participating students held positive attitudes toward the use of PA activities, but they viewed online
PA as a technical tool to facilitate assessment processes, rather than as a learning aid. Male students had more positive
attitudes toward PA than females did, and students with previous PA experiences had less negative attitudes toward PA. A majority
of these students suggested that the PA score should be counted as a small part of the total course grade, and there was an
effect of the perceived importance of PA score on students’ attitudes toward these four subscales. 相似文献

Zusammenfassung Der vorliegende Beitrag besch?ftigt sich aus der Perspektive von Theorien zum Kompetenzerwerb mit dem Zusammenhang zwischen
dem fachspezifischen Professionswissen von Mathematiklehrkr?ften und ihrer Ausbildung und beruflichen Fortbildung. Dabei wurden
institutionelle Unterschiede der Lehramtsausbildung wie auch individuelle Unterschiede im Studienerfolg, der Berufserfahrung
und der besuchten beruflichen Fortbildungen untersucht. Die Analysen basieren auf Daten von 195 Mathematiklehrkr?ften, die
an der COACTIV-Studie teilnahmen. Unsere Ergebnisse zeigen, dass sich Lehrkr?fte unterschiedlicher Lehr?mter deutlich in ihrem
professionellen Wissen unterscheiden und dass insbesondere der Erfolg im Studium mit besseren Leistungen im Fachwissen und
im fachdidaktischen Wissen zusammen hing. Wir diskutieren Implikationen unserer Ergebnisse vor dem Hintergrund der Lehramtsausbildung
und beruflicher Fortbildungen.
