Students’ misconceptions of statistical inference: A review of the empirical evidence from research on statistics education     

Ana Elisa Castro Sotos  Stijn Vanhoof  Wim Van den Noortgate  Patrick Onghena 《Educational Research Review》2007,2(2):98-113

A solid understanding of inferential statistics is of major importance for designing and interpreting empirical results in any scientific discipline. However, students are prone to many misconceptions regarding this topic. This article structurally summarizes and describes these misconceptions by presenting a systematic review of publications that provide empirical evidence of them. This group of publications was found to be dispersed over a wide range of specialized journals and proceedings, and the methodology used in the empirical studies was very diverse. Three research needs rise from this review: (1) further empirical studies that identify the sources and possible solutions for misconceptions in order to complement the abundant theoretical and statistical discussion about them; (2) new insights into effective research designs and methodologies to perform this type of research; and (3) structured and systematic summaries of findings like the one presented here, concerning misconceptions in other areas of statistics, that might be of interest both for educational researchers and teachers of statistics.  相似文献   

Role of the Undergraduate Student Research Assistant in the New Millennium   总被引：1，自引：0，他引：1

In this study, we analyze the contribution of the undergraduate student who participates in the process of generating scientific data and developing a research project using Brazilian research as an example. Historically, undergraduate students have performed the critical role of research assistants in developing countries. This aspect has been underappreciated as a means of generating scientific data in Brazilian research facilities. Brazilian educational institutions are facing major age-related generational changes among the science faculty within the next 5–10 yr. A lack of adequate support for graduate students leads to a concern that undergraduates will not be interested in choosing research assistant programs and, subsequently, academic research careers. To remedy this situation it is important to focus on ways to encourage new research careers and enhance university–industry collaborations.  相似文献   

V + H: Hybrid architecture for DSS and OLTP     

María del Pilar Angeles  Victor González Castro 《International Journal of Information Management》2013,33(6):940-947

Previous research has been done to identify the best pragmatic approach that DBMSs must follow to manage different workloads. Some approaches have followed the “One size fits all” approach, trying to incorporate all features in a row-oriented DBMS (also called horizontal) to manage both OLTP and DSS workloads. Additionally, there have been specialized DBMS, following a columnar approach (also called vertical), that focuses on the growing demand to efficiently manage DSS workloads. This paper proposes a combination of both vertical and horizontal DBMS to best manage OLTP and DSS workloads. We have used mature, commercially available products from a single vendor and developed a custom middleware Decision Query Module that identifies the best option for most efficient execution of a query. This V + H architecture also offers the functionality of a mirrored DB without paying twice for storage.  相似文献   

Development of Manager‐Academics at Institutions of Higher Education in Catalonia     

Diego Castro  Marina Tomàs 《Higher Education Quarterly》2011,65(3):290-307

Managers at Spanish universities are having to deal with increasingly complex managerial tasks as a result of current changes in higher education. This paper presents the results of a study into the professional development of deans and department heads at universities in Catalonia. At management level, these universities are typically based on an elected, rotating model rather than an appointed or permanent one. The findings from 23 qualitative interviews and a focus group identified three phases in the development of academic management: learning and contextualization, development of functions, and the institutional projection and transmission of management tasks.  相似文献

Measuring Space and Furniture Occupancy in Academic Libraries: From Data Gathering to Visualization     

Rodrigo Castro  Carli Spina  Yaqing Xu 《图书馆管理杂志》2013,53(6):579-605

Abstract

Academic libraries are a vital space for collaboration, socialization, research, and quiet study. To support these needs, they must offer a variety of environments, noise levels, and furniture to support varying student needs. However, it can be difficult to understand these specific needs and properly balance the types of spaces and seating alternatives to optimally meet them. This article describes a space usage study undertaken to determine patron needs and preferences and the resulting visualization of the data using Tableau Public. The project provided important insights into patron space preferences and use, and the methodology can be replicated at other institutions.  相似文献

The Role of Reflection in the Effects of Community Service on Adolescent Development: A Meta‐Analysis     

Anne van Goethem  Anne van Hoof  Bram Orobio de Castro  Marcel Van Aken  Daniel Hart 《Child development》2014,85(6):2114-2130

This meta‐analysis assessed the effect of community service on adolescent development and the moderation of this effect by reflection, community service, and adolescent characteristics to explicate the mechanisms underlying community service effects. Random effects analyses, based on 49 studies (24,477 participants, 12–20 years old), revealed that community service had positive effects on academic, personal, social, and civic outcomes. Moderation analyses indicated that reflection was essential; the effect for studies that include reflection was substantial (mean ES = .41) while community service in the absence of reflection yielded negligible benefits (mean ES = .05). Effects increased when studies include more frequent reflection and community service, reflection on academic content, and older adolescents. These findings have implications for understanding and improving community service.  相似文献   

Acculturative Stress and Depressive Symptomatology Among Mexican and Mexican American Students in the U.S.: Examining Associations with Cultural Incongruity and Intragroup Marginalization     

Miguel Ángel Cano  Linda G. Castillo  Yessenia Castro  Marcel A. de Dios  Angelica M. Roncancio 《International journal for the advancement of counseling》2014,36(2):136-149

This study examined associations of intragroup marginalization and cultural incongruity with acculturative stress and depressive symptoms among 155 undergraduate U.S. college students of Mexican heritage. Findings indicate that perceived interpersonal distancing by the family (intragroup marginalization) and perceived lack of cultural fit between the respondent and academic institution (cultural incongruity) had statistically significant direct and indirect effects on depressive symptoms via acculturative stress. Results also show that 39.7 % of the variance corresponding with depressive symptoms was accounted for by intragroup marginalization, cultural incongruity, acculturative stress, and other exogenous variables.  相似文献
