Abstract

This mixed methods study examined how engagement in robotics and game design influenced students’ self-efficacy, STEM attitudes, and computational thinking (CT) skills. Predominantly African-American students engaged in engineering and computer science tasks during informal learning environments. Results revealed students’ self-efficacy scores on computer gaming increased significantly. Focus group data supported these findings, revealing that computer programing was challenging, but students enjoyed the tasks, added elements of culture in some cases, and valued the agency the tasks provided. Focal students were also able to make connections to STEM-related careers. Observational data demonstrated that focal students exhibited substantive CT during robotics and moderate CT during game design. Results support the idea that robotics and game design may be used to broaden underrepresented students’ participation in STEM.  相似文献   

Stratification of environmental education and education for sustainable development in Australia: an analysis of positions vacant advertisements   总被引：1，自引：1，他引：0  

Joy Hardy 《Environmental Education Research》2008,14(2):165-174

Positions vacant advertisements discursively construct employment sectors, employers and employees. This paper uses content analysis, systemic functional linguistics and critical discourse analysis to investigate the discursive construction of environmental education and education for sustainable development through positions vacant advertisements placed with Australian online recruitment agencies. The results suggest a disturbing stratification between environmental education and education for sustainable development with respect to the terms and conditions, and the power dynamics operating in each sector.  相似文献   

Performance analysis for ordered selection combining schemes in Nakagami-m environments     

Joy Iong-Zong Chen 《Journal of The Franklin Institute》2005,342(6):638-656

Ordered statistics is applied in this paper to analyze the performance of ordered selection combining schemes with different modulation receptions operating in Nakagami-m fading environments. The ordered selection combining will be adapted to include the conventional selection combining (SC), the second-order diversity combining (SC-2), and the third-order diversity combining (SC-3). All the results are validated by comparing the special case Rayleigh distribution with the fading figure m=1 in the Nakagami-m distribution. The results show that SC is in performance the worst in both coherent and non-coherent schemes, as expected. The performance differences between SC-2 and MRC, and SC-3 and EGC are not significant when the diversity order L?3, but the differences will increase when L?5.  相似文献   

A unified approach to average LCR and AFD performance of SC diversity in generalized fading environments     

Joy Iong-Zong Chen 《Journal of The Franklin Institute》2007,344(6):889-911

The average level crossing rate (LCR) and average fading duration (AFD) criterions are applied to analyze the selection combining (SC) diversity for wireless communication systems over correlated-Rayleigh and correlated-Rice fading in this paper. The scenarios of the fading channel models are characterized as 4 generalized and experimental distributions, e.g., Rayleigh, Rice, Nakagami-m, and Weibull distributed statistics. Moreover, both of independent and correlated proprieties between branches are also involved for consideration. For purpose of unifying and clarifying the average LCR and AFD performance formulas results from the evaluation for SC diversity, it is not only the results from our research presented, but some of the published results are also cited and illustrated by numerical evaluation again in this study.  相似文献

Seeking comfort: How and why preservice teachers use internet resources for lesson planning     

Amanda G. Sawyer  Joy Myers 《Journal of Early Childhood Teacher Education》2018,39(1):16-31

This study examined 158 lesson plans at one institution across two teacher education programs, inclusive early childhood and elementary education, to determine the impact of Internet usage as inspiration on preservice teachers’ lesson plans. Fisher’s exact test determined statistically significant differences between the Internet use of preservice teachers in the two programs. The data revealed that the preservice teachers in the elementary education program used more Internet resources when planning lessons compared to the preservice teachers in the inclusive early childhood program. Follow-up interviews suggest that the preservice teachers in the inclusive early childhood program had more practicum field experiences, thus increasing their use of physical resources and reducing their use of Internet resources.  相似文献   

Responding to Change: Challenges for Professional Education in the Museum Sector     

Joy Davis 《Curator: The Museum Journal》2005,48(4):427-438

Abstract This paper reflects on the changes confronting educators involved in museum professional development, drawing on the experience gained in working with a wide range of learners, instructors and content issues through the Cultural Resource Management Program at the University of Victoria in British Columbia. Reflecting the society as a whole, professional education programs are called to respond to the needs of learners, and to institutional priorities for competency development and instructional design and delivery issues. Given the near‐universal pressures on museums and educational institutions, it is hoped that these impressions and perspectives are of broad relevance to a range of academic and professional museum studies programs across Canada and beyond.  相似文献   

Developing Human Capital: training and mentoring for principals     

Tony Bush  Joy Chew 《Compare》1999,29(1):41-52

The links between educational development and economic capability are widely recognised and have provided part of the rationale for the shift to market concepts of education in many countries. As more functions have been devolved to school level, it has become increasingly evident that principals require training and development to carry out their new responsibilities and to lead improvement in their schools. In Singapore, aspiring principals take a 1‐year training course which includes mentoring by an established principal. In England and Wales, the new National Professional Qualification for Headship is undertaken on a part‐time basis and adopts a quasi competence model without a mentoring dimension. This article compares the two approaches and concludes that training is likely to be more effective if mentoring is a central component of the process.  相似文献

Surprise,Hurt, and Anger as Emotional Responses to Expectancy Violations Following Feedback Messages     

Lance Kyle Bennett  Xavier Scruggs  Joy Melody Woods 《Communication Research Reports》2020,37(1-2):22-33

ABSTRACT

Using expectancy violations theory, this study examined how the communication of unexpected feedback messages evoke emotional responses. A convenience sample (N = 309) reported instances of unexpected feedback within the last month. Results showed that receipt of the feedback message types were considered moderate-to-high violations. Violation expectedness and valence were negatively associated with the emotional responses, but violation importance was positively associated with the emotional responses. Finally, hurt and anger (but not surprise) were positively linked to perceptions of relational damage between the message sender and receiver. Taken together, our study demonstrates that expectancy violations are connected to emotions and relational outcomes.  相似文献
