Breaking it Down: Engineering Student STEM Confidence at the Intersection of Race/Ethnicity and Gender

It is generally accepted that engineering requires a strong aptitude for mathematics and science; therefore, students’ judgments regarding their competence in these areas as well as engineering likely influence their confidence in engineering. Little is known about how self-confidence in science, mathematics, and engineering courses (STEM confidence) varies at the intersection of race/ethnicity and gender. To fill this gap, this study examined the STEM confidence of multiple groups in undergraduate engineering programs. Results indicated that although some underrepresented groups may have lower STEM confidence overall, this finding no longer applies to all groups after controlling for personal, environmental, and behavioral factors. Specifically, African-American and Hispanic men report higher average STEM confidence than White men after controlling for these associated measures. In addition, White women continue to report lower average STEM confidence than White men after controlling for these measures, while other groups do not differ from White men. Further, many elements of student perception, including student views of professors, comparisons to peers, perceptions of the field as rewarding, and desirability of chosen major are positively associated with student STEM confidence. The changing patterns of significance for race/ethnicity and gender groups between the two models indicate that personal, environmental, and behavioral factors have different relationships with STEM confidence levels for different groups. This study contributes an understanding that gender differences in STEM confidence are not indifferent to racial and ethnic context. Social-cognitive theory provides a valuable framework for studying student academic confidence and would improve future self-confidence research.     

The Status of Genetics Curriculum in Higher Education in the United States: Goals and Assessment

We review the state of genetics instruction in the United States through the lens of backward design, with particular attention to the goals and assessments that inform curricular practice. An analysis of syllabi and leading textbooks indicates that genetics instruction focuses most strongly on foundations of DNA and Mendelian genetics. At the same time, a survey of faculty indicates that other concepts, such as the application of genetics to society or the environment, are viewed as equally or even more important than foundation concepts. This disconnect suggests a need for more explicit goal setting prior to curriculum development. We also review the relationship between concept inventories, multiple-choice tests measuring conceptual understanding, and curricular goals. Existing concept inventories offer a strong foundation on which to build community-developed concept assessments of genetics knowledge. Concept assessments such as these would allow the genetics education community to test hypotheses of curricular change.     

Rising like a glorious turkey from the ashes of burnout

Abstract

Mississippi State University (MSU) Libraries recently held its first library-centered First-Year Experience course. To develop an appealing class for first-semester students, the authors turned to game-based learning in conjunction with a portion of the school identity to teach the ACRL Framework for Information Literacy that they hoped would resonate with the students. This article discusses the games that were implemented along with the corresponding IL framework and assessment of the course. The authors were able to increase student scores from 66.4% (pretest average) to 84.31% (post-test average).     

Virtually the Same: Comparing the Effectiveness of Online Versus In-Person Library Tours

ABSTRACT

The use of virtual or Web-based tours is on the rise in academic libraries, but with the loss of face-to-face contact and direct experience with the library's physical spaces, questions abound about this format's efficacy. Do online tour experiences measure up to those of a guided, face-to-face tour? Do online tours help mold students' perceptions of the library, while imparting important practical knowledge about the library's resources and services? Librarians at Kent State University in Kent, Ohio, recently confronted these questions, as they added an option for an online library tour to a large library tour program for freshman that had previously been offered strictly through guided, librarian-led tours. This paper presents the results of a preliminary study comparing the efficacy of learning and affective outcomes between face-to-face library tours and online library tours at Kent State University.     

Use and perceptions of information among family physicians: sources considered accessible,relevant, and reliable

Objectives:

The research determined (1) the information sources that family physicians (FPs) most commonly use to update their general medical knowledge and to make specific clinical decisions, and (2) the information sources FPs found to be most physically accessible, intellectually accessible (easy to understand), reliable (trustworthy), and relevant to their needs.

Methods:

A cross-sectional postal survey of 792 FPs and locum tenens, in full-time or part-time medical practice, currently practicing or on leave of absence in the Canadian province of Saskatchewan was conducted during the period of January to April 2008.

Results:

Of 666 eligible physicians, 331 completed and returned surveys, resulting in a response rate of 49.7% (331/666). Medical textbooks and colleagues in the main patient care setting were the top 2 sources for the purpose of making specific clinical decisions. Medical textbooks were most frequently considered by FPs to be reliable (trustworthy), and colleagues in the main patient care setting were most physically accessible (easy to access).

Conclusions:

When making specific clinical decisions, FPs were most likely to use information from sources that they considered to be reliable and generally physically accessible, suggesting that FPs can best be supported by facilitating easy and convenient access to high-quality information.

Highlights

• Medical textbooks were the most popular information source for family physicians'' (FPs'') clinical decision-making purposes, and medical journals were the most popular information source for the purpose of updating FPs'' general medical knowledge.
• FPs considered medical textbooks to be the most reliable (trustworthy) source, colleagues the most physically accessible, and continuing medical education the most relevant and intellectually accessible.
• The lowest ranked information sources across all four attributes were personal digital assistants, mental health professionals, pharmaceutical sales representatives, and other decision aids.

Implications

• The most popular information sources for clinical decision-making purposes among FPs were sources characterized as reliable and generally physically accessible.
• This study suggests the need for further research into interventions that target information access barriers in FPs'' practice settings and the promotion of reliable evidence for FPs'' clinical decision-making purposes.

     

Neuroimaging: Directions and Potentials for Communication Research

The field of Communication Studies and the field of Social Neuroscience have a common goal of studying and understanding human social behavior. This article invites those in the Communication field to learn about the neuroimaging practices that are common in the Social Neuroscience field. The article relays the basics of neuroimaging, especially functional Magnetic Resonance Imaging (fMRI). Using a recent article on violent media perception as an example, we will go over the details of how neuroimaging studies are designed, analyzed and interpreted, with attention paid to common pitfalls and current trends in the field. In addition, for one interested in the potential for neuroimaging, suggestions on how to initiate such research pursuits are detailed.     

An Examination into the Dyadic Effects of Mood in Social Interactions

Much of the research on mood and communication has failed to examine the potential social and interactive attributes of mood suggested by studies involving affective contagion. An experiment involving 63 dyads was conducted manipulating the mood of both individuals involved to investigate these issues. Results suggest that the mood of both individuals can potentially impact an individual within an interaction. The findings are discussed, and future directions are suggested.     

Faculty and Librarian Perceptions of a New Faculty Purchase Program

This study explores new faculty members' and librarians' perceptions of a program that provides each new faculty member with funds to purchase materials supporting their teaching and scholarship. The article describes the results of a survey of perceptions of the faculty and librarians who have participated in the program at Illinois State University. The findings suggest that the program has not been successful as a recruitment tool but has been very valuable for establishing early and strong subject liaison relationships with new faculty members.     

A ‘powerful,creative history’: the reticence of women architects to donate their professional records to archival repositories

The article reports the findings from research investigating the impact of international standards for records management. This is a significant issue for the recordkeeping community given the significant resourcing devoted to the development of international standards. Previous attempts to measure impact have met with little success, so this research approached the problem area from a new angle, namely the indirect influence of standards on practice via their use in education and training. Data was collected from a global survey of educators and trainers. Findings demonstrate that the standards are being used extensively at undergraduate and postgraduate level as well as in vocational training. However, a number of barriers to use are identified. The research provides a strong foundation for further investigation of impact and use of the international standards.     

Use of Polarised Light Microscopy to Improve Conservation of Parchment

ABSTRACT

The preservation state of parchment primarily depends on the structure of the collagen fibre network, which in turn is responsible for optical anisotropy, i.e. birefringence. Polarised light microscopy can therefore be used as a non-invasive technique that allows recording of birefringence distribution in the parchment, which directly relates to stress–strain distribution. Using samples from diverse sources (commercial parchment, parchment used by restorers for book binding, and parchment fabricated for the purpose of this study), we assessed the capability of polarised light microscopy for various diagnostics. We performed, for instance, identification of gelatinised regions, layered or ?brous regions in parchment cross section, qualitative analysis of parchment fat content (lipids), observation of stress-induced patterns resulting from tensile tests, and observation of water diffusion. These proof-of-principle experiments extend the capability of polarised light microscopy far beyond its common use and open the path to its deployment in conservation studies.
