Rethinking mobile delivery: using Quick Response codes to access information at the point of need

This article covers the use of Quick Response (QR) codes to provide instant mobile access to information, digital collections, educational offerings, library website, subject guides, text messages, videos, and library personnel. The array of uses and the value of using QR codes to push customized information to patrons are explained. A case is developed for using QR codes for mobile delivery of customized information to patrons. Applications in use at the Libraries of the University of Utah will be reviewed to provide readers with ideas for use in their library.     

Does Displaying the Class Results Affect Student Discussion during Peer Instruction?

The use of personal response systems, or clickers, is increasingly common in college classrooms. Although clickers can increase student engagement and discussion, their benefits also can be overstated. A common practice is to ask the class a question, display the responses, allow the students to discuss the question, and then collect the responses a second time. In an introductory biology course, we asked whether showing students the class responses to a question biased their second response. Some sections of the course displayed a bar graph of the student responses and others served as a control group in which discussion occurred without seeing the most common answer chosen by the class. If students saw the bar graph, they were 30% more likely to switch from a less common to the most common response. This trend was more pronounced in true/false questions (38%) than multiple-choice questions (28%). These results suggest that observing the most common response can bias a student''s second vote on a question and may be misinterpreted as an increase in performance due to student discussion alone.     

Seven plus or minus two

For over 50 years, seven plus or minus two has been a commonly used guideline for gauging how many chunks of new information should be presented at one time in learning and performance situations. Often cited as the limit of working memory, this guideline was created as a result of misinterpreting an article by Miller (1956). More recent studies suggest that the limit for working memory is more like three, and sometimes four, with various factors influencing the capacity of an individual's working memory. Given too much novel information at one time, learners and performers can be derailed by cognitive overload. Instructional designers and performance consultants can adjust the presentation of new information to manage intrinsic, extraneous, and germane cognitive load. This column provides suggestions about how to reduce cognitive overload to improve learning and performance.     

From the research: Myths worth dispelling: Seriously,the game is up

When new media and delivery systems are introduced, they are often accompanied by claims that they provide increased learning. The temptation to ascribe learning powers to delivery systems is strong, as evidenced by repeated attempts over many decades to do so. A relatively new arrival, serious games are currently the recipient of much attention in this regard. In a new meta‐analysis of learning in training programs with or without games, Sitzmann (in press) suggests that delivering training via simulation games enhances learning, while she also acknowledges that instructional methods—not delivery systems—provide the ingredients that facilitate learning. If blog posts and Internet articles provide a useful indication, many practitioners are furthering claims for increased learning and retention via serious games. These claims provide fertile ground for a new set of myths about this relatively new delivery system. Before choosing to invest in acquiring or developing serious games, decision makers should consider (a) instructional methods and (b) whether they will realize benefits from a cost and implementation perspective. They should not select serious games because of claims that the games will intrinsically enhance learning.     

Reading interventions for struggling readers in the upper elementary grades: a synthesis of 20 years of research

A synthesis of the extant research on reading interventions for students with reading difficulties and disabilities in fourth and fifth grade (ages 9–11) is presented. Thirteen studies with treatment/comparison study designs and eleven single group or single subject studies were located and synthesized. Findings from the 24 studies revealed high effects for comprehension interventions on researcher-developed comprehension measures. Word recognition interventions yielded small to moderate effects on a range of reading outcomes. Few studies were located implementing vocabulary and multi-component interventions.     

Increasing Diversity in Science and Health Professions: A 21-Year Longitudinal Study Documenting College and Career Success

Despite decades of precollege science education programs, African Americans, Latinos, and Native Americans remain critically underrepresented in science and health professions. This report describes college and career outcomes among graduates of the Stanford Medical Youth Science Program (SMYSP), a 5-week summer residential program for low-income high school students among whom 97% have been followed for up to 21 years. Approximately 24 students are selected annually, with participation limited to low-income students who have faced substantial personal hardships. Undergraduate and medical students provide key program leadership and training. The curriculum is based on science inquiry education and includes hospital internships, anatomy practicums, research projects, faculty lectures, college admissions/standardized test preparation, and long-term college and career guidance. A total of 476 high school students participated between 1988 and 2008, with 61% from underrepresented ethnic minority groups. Overall, 78% of African American, 81% of Latino, and 82% of Native American participants have earned a 4-year college degree (among those admitted to college, and excluding those currently attending college). In contrast, among 25–34-year old California adults, 16% of African Americans, 8% of Latinos, and 10% of Native Americans earn a 4-year college degree. Among SMYSP’s 4-year college graduates, 47% are attending or have completed medical or graduate school, and 43% are working as or training to become health professionals. SMYSP offers a model that expands inquiry-based science education beyond the classroom, and recognizes the role of universities as “high school interventionists” to help diversify health professions.
