Put Theory Into Practice

Audrey J. Jaeger, Stephany Dunstan, Courtney Thornton, Alyssa B. Rockenbach, Joy G. Gayles, and Karen J. Haley argue that applying our theoretical frameworks in everyday decision making will help us to be more efficient and effective—and they provide a user‐friendly analogy to guide us in this endeavor.     

Electronic Learning Delivery Systems: A Selection Model

Electronic learning delivery systems discussed include satellite networks, teleconferencing, Internet/Intranet networks, desktop multimedia, electronic performance support systems (EPSS), transportable audio/video (i.e., systems relying primarily on physically transportable audio-and videotaped materials), and the electronically enhanced classroom. Selecting one of these systems can be a daunting task when all relevant issues are considered. The selection model described in this article narrows the choices to the system most likely to be instructionally, economically, and technologically appropriate. After establishing working definitions, the model suggests four stages of user activity: 1) Assessing several important overall factors, including outcomes and conditions of learning, economics, synchronicity and location, and organizational culture; 2) Rating the importance of several learning system attributes to the training project; 3) Selecting the system that most ideally supports the attributes which the user has rated as important; and finally, 4) Validating the selection by reviewing the final choice in light of first stage overall factors.     

Introduction of Molecular Methods into a Food Microbiology Curriculum

Maintaining current, relevant curriculum in undergraduate Food Microbiology courses is essential for training future experts in food quality and safety. Having an understanding of the fundamental techniques (for example, polymerase chain reaction [PCR]) that are used in the food industry and regulatory agencies is critical for students entering the workforce. The purpose of this study was to assess the efficacy of integrating molecular methods into an undergraduate Food Microbiology course in both lecture and laboratory settings. Modules on PCR and pulsed‐field gel electrophoresis (PFGE), both of which are currently used by government agencies and the food industry to investigate the presence and persistence of foodborne pathogens, were developed, introduced, and evaluated among 269 students over 4 y. Multiple teaching and learning styles were incorporated through (i) traditional lecture format on the basics of PCR and PFGE; (ii) hands‐on group activities to build upon the lecture instruction; (iii) performing PCR and PFGE in the laboratory; and (iv) group discussions to analyze results from laboratory exercises. Pre‐ and postinstruction evaluations revealed significant increases in understanding and application of both methods in lecture and laboratory settings as demonstrated by 0.60 and 0.51 mean normalized gains for respective PCR and PFGE lectures and 0.50 and 0.56 mean normalized gains in respective labs. Academic year significantly impacted score improvement, potentially due to hidden factors, such as previous exposure to material and student aptitude. This study provides the platform for successful introduction of molecular techniques in an undergraduate Food Microbiology course. The guidelines and materials developed by our group are publicly available for use by other institutions.     

The Correlation Between Brain Development, Language Acquisition, and Cognition

There continues to be a debate whether educators should use brain research to their advantage in the classroom. This debate should not prevent educators from using their new found knowledge toward enhancing their students’ learning. By understanding how the brain learns, educators are able to determine what developmental level the child is physically, mentally, socially, and cognitively. The more knowledge an educator has and applies, the better the children will learn, and our future leaders will be better educated.     

Celebrating the Past,Creating the Future: 50 Years of Community College Research

The Council for the Study of Community Colleges (CSCC) celebrated its 50th anniversary in 2008. This article summarizes the establishment of the Council and sets it in the context of the development of the community college movement. Highlights of research conducted by CSCC members to address contemporary issues facing community colleges are described. A summary of insights offered by members during a 2008 plenary session, research presented at the 50th annual conference, and key community college leaders are described in the context of the historical evolution of community college research and future directions.     

Nameability supports rule-based category learning in children and adults

The present study tested the hypothesis that verbal labels support category induction by providing compact hypotheses. Ninety-seven 4- to 6-year-old children (M = 63.2 months; 46 female, 51 male; 77% White, 8% more than one race, 4% Asian, and 3% Black; tested 2018) and 90 adults (M = 20.1 years; 70 female, 20 male) in the Midwestern United States learned novel categories with features that were easy (e.g., “red”) or difficult (e.g., “mauve”) to name. Adults (d = 1.06) and—to a lesser extent—children (d = 0.57; final training block) learned categories composed of more nameable features better. Children's knowledge of difficult-to-name color words predicted their learning for categories with difficult-to-name features. Rule-based category learning may be supported by the emerging ability to form verbal hypotheses.     

Talking to children about science is harder than we think: characteristics and metacognitive judgments of explanations provided to children and adults

Adults modify the way they speak to children to support children’s learning across several domains. However, no previous research has studied whether adults change their language when explaining science to children. The current study examined if and how adults change the manner in which they talk about science when providing explanations to children vs. providing explanations to other adults. Participants (N = 81) were video recorded while explaining basic science concepts to children and adults. Recordings were later analyzed to determine if and how participants changed the quality and content of their explanations. The results confirmed that adults did change their explanations when talking to children about science by providing more potentially beneficial, but also disadvantageous, information. Participants perceived that they provided more accurate explanations to children, but appeared to be making metacognitive judgments largely based upon the changes made that could be beneficial to learning. Taken together, this work suggests that science may be a domain in which adults are not well equipped to modify and monitor their language to children.

Unfolding narrative meaning over time: The contributions of mother–daughter conversations of difficulty on daughter narrative sense-making and well-being

Recent narrative theorizing suggests that humans process their difficult experiences by not only creating stories—called individual narrative sense-making (NSM)—but also by telling those stories with others—called communicated narrative sense-making (CNSM). The present study investigated the relationship between individual and communicated NSM to understand the effects of interpersonal communication on intrapersonal meaning-making and well-being. In this longitudinal, laboratory-based study, 62 mother–daughter pairs wrote and discussed stories of daughters’ difficulty. Findings revealed that CNSM—particularly turn-taking, coherence, and daughters’ perspective-taking—predicted increased positivity in daughters’ stories over time, suggesting that CNSM contributes to “re-authoring” of individual stories. Limited effects emerged for CNSM and well-being. Findings expanded knowledge about the interconnections between intrapersonal and interpersonal communication, and well-being.
