Bringing Computational Thinking to STEM Education
No full textAbstractToday, as advanced technologies and cloud computing tools emerge, it is imperative that such innovations are sustained with knowledge and skill set among STEM educators and practitioners. In this paper, the author reports on a project, HBCU-UP II, that works on bringing Computational Thinking to Science, Technology, Engineering, and Mathematics (STEM) disciplines. A Computational-Thinking based strategy is adopted to enforce thinking computationally in STEM gate-keeping courses. The paper presents framework, implementation and outcomes. This on-going project contributes to efforts to establish computational thinking as a universally applicable attitude that is meshed within STEM conversations, education, and curricula. This paper will be particularly useful for researchers interested in Computational Thinking and its applications in STEM education, in particular and higher education in genera
Linking Perceived Electronic Service Quality and Service Loyalty on the Dimensional Level: An Aspect of Multi-Channel Services
Get PDFUnderstanding the Quality of Informational Health Websites: The Application of the Kano Model
Get PDFThis study reports on an exploratory investigation of quality criteria classification of informational health websites using the Kano model. The results showed that quality features are of three types: (i) basic features which are the minimal requirements the consumers expect; (ii) performance features, which are the ones that maximize the consumers satisfaction with the health website; and (iii) the exciting features which are the delighters, the consumers do not consciously expect. The findings indicate that providing accessible website with high quality content that are friendly usable and trustworthy are basic quality features. On the other hand, features of visually appealing website, and human and/or automated feedback mechanisms are performance features that maximize the consumers satisfaction. Developing a health website that incorporates culturally-appropriate materials and employs interactive learning tools such as simulation or puzzles delights consumers and makes the website a leader in it space
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Developing an Instrument for Measuring Electronic Shopping Service Quality: E-SQUAL
Get PDFIn contrast to service quality in traditional facilities (e.g., stores, restaurants, clinics) that enjoyed an extensive research during the last 20 years and resulted in a solid base for service quality measurement and management, service quality that is delivered via the web, termed here electronic service quality, lacks maturity. The present study develops and validates an instrument for measuring electronic service quality of online shopping sites. Using two independent datasets, a conceptual framework of e-service quality is proposed and empirically tested. This research develops an E-SQUAL scale consisting of six dimensions: information quality, web usability, reliability, responsiveness, assurance and personalization. The developed scale demonstrates strong psychometric properties in terms of reliability and validity. Conclusion, implications and limitations of the study are presented
HeWEK: Measuring the Health Website Quality From the Perception of the African American
Get PDFUnintentionally, the growth of health websites deepened health disparities between population subgroup as it considers the perception of some sub-populations and ignore the needs of others when designing health websites. This paper presents a study that aims onto considering the perception of the African American in identifying the quality attributes of health websites. Based on focus group research and two-round factor analysis, findings indicate that quality of health websites is a function of dimensions of Aesthetic Design’, ‘Website Usability’, ‘Information Quality’, ‘Information Architecture’, ‘Responsiveness’, ‘Trust’, ‘Identity’, ‘Appropriateness to Culture’, and ‘Learnability’. The paper provides useful messages for website designers, website content mangers, usability practitioners, and web-based healthcare program managers. Also, theoretical implications and limitation of the study are presented
