Dynamic characteristics of mental models and dynamic visual displays

Mental models are hypothetical constructs for explaining human cognitive processes of understanding external reality, translating the reality into internal representation and utilizing it in problem solving. Three experiments were conducted to investigate important characteristics of mental models, their influence on task performance, and instructional strategies facilitating their formation. The experiments were conducted in computer-based training environments designed to teach troubleshooting electronic logic circuits. The results suggested: (a) dynamic characteristics of mental models are important for solving problems if understanding functional behaviors of the system is required to perform the task; (b) dynamic characteristics of mental models are determined primarily by subjects' understanding of the system features and functions more than by the visually presented training contents of the system; and (c) motion simulating system functions in visual displays is more effective than static visual displays in facilitating the formation of dynamic characteristics of mental models. Consequently, dynamic visual displays are more effective than static visual displays for teaching electronic troubleshooting skills. These findings provide direct implications for the development of training programs.     

Early Education Essentials: Validation of Surveys Measuring Early Education Organizational Conditions

Research Findings: The Early Education Essentials surveys use teacher and parent perceptions to measure 6 organizational conditions of early childhood education programs, extending and complementing existing measures of early childhood care and education (ECE) quality constructs. This study tests the reliability and concurrent validity of the Early Education Essentials in 81 school- and community-based ECE sites in a large Midwestern city selected using a stratified random sampling method. Using a Rasch item response theory model, scales were created; theory and exploratory factor analyses combined scales into higher level constructs called essentials. Multilevel models took into account individual measurement error to create site-level essential scores and assessed relationships between programs’ essential scores and site-level teacher–child interactions scores and student attendance. Findings suggest that the Early Education Essentials is reliable in multiple ECE settings; it is sensitive to site-level differences; and some, but not all, organizational conditions measured are associated in expected directions with site-level metrics indicative of center-based ECE quality. Practice or Policy: The Early Education Essentials has the potential to provide leaders and practitioners with actionable data about organizational supports that enable ECE practitioners to be more effective in their daily work with children and families.     

HUMAN SUBJECTS AND COGNITIVE AGING RESEARCH: A UNIQUE SOLUTION TO A PERENNIAL PROBLEM

A fundamental concern of cognitive aging researchers is to find a representative sample of healthy, older adults who are willing to participate in experimental research. There are essentially two methods for marshalling a sizable body of older research participants. One can solicit the aid of local community‐dwelling adults through civic and church‐related organizations. Alternatively, one can travel to specific locations where elderly people are likely to congregate, for example, a retirement community. In this article, we describe our experiences with these two methods of research‐participant recruitment. The processes involved in both securing and utilizing a local body of research volunteers are presented first. We then discuss two subject‐testing expeditions outside of the university environment that have been highly successful. In the final section, we contrast selected demographic characteristics of our local and off‐site research volunteers and discuss the implications of differences between these two populations for conducting research with aged people.     

Validation of the Korean version Gender Role Conflict Scale for Adolescents

The objective of this study was to examine the usefulness of the Korean version of the Gender Role Conflict Scale for Adolescents (GRCS-A; Blazina et al. 2005) in Korea. Korean high school students (N = 374) completed the K-GRCS-A. Results of confirmatory factor analysis supported the original 4-factor structures. Reliability was acceptable to satisfactory limits. Further evidence of construct validity was found in modest correlations with psychological well-being variables. Taken together, this study sustained the utility of the K-GRCS-A.     

Communication practices in Korea

The communication practices of Koreans are explored which are divergent from those employed elsewhere in the world. Distinction in social behavior impinging on communication include Confucianistic ethics, filial piety, age, gender, and hierarchical structure. Verbal and nonverbal differences relate to maintaining harmony in interpersonal relationships. The essay concludes with analyses from six research reports comparing Korean communication styles to those in other cultures.     

EFFECTS OF AGE AND INSTRUCTIONS ON TEACHING OLDER ADULTS TO USE ELDERCOMM,AN ELECTRONIC BULLETIN BOARD SYSTEM

This study focused on how to train older adults to perform computer procedures. Young-old (aged 60 74 years) and old-old (aged 75 years and older) adults were instructed on how to use ELDERCOMM , an electronic bulletin board system using one of two types of text-based instructions. The first set of directions consisted of illustrated, step-by-step instructions (simple condition). The second set of directions included the same step-by-step instructions as in the first set, but explanatory information about how the bulletin board system worked was added before the     

End-of-Life Decision Making in Older Korean Adults: Concerns,Preferences, and Expectations

This study explored Korean older adults’ concerns and preferences regarding end-of-life care and the expected role of physicians in the decision making process. The purpose was to assist health care professionals, in particular, physicians, to better understand how to interact with Korean older adults. A qualitative method using in-person interviews was conducted with Korean older adults (N = 54). The seven main themes generated in this study included the following: (a) life-sustaining treatments and hope for quality of life; (b) physician expert status; (c) truth telling and ethics; (d) preferred way to disclose bad news; (e) physician's role to treat, (f) potential misuse of life-sustaining treatments; and (g) priority of patients’ preferences. Overall, study participants generally anticipated a larger role for physicians in their own end-of-life decision making, though some expressed concerns about the outcome of giving such power to physicians, especially in agreeing to life-sustaining treatments. Although culture provides one important clue about expectations, it is always crucial for health care providers to ask about individual preferences and to develop an open communication style to decrease distress. Our findings highlight the importance of understanding concerns and preferences regarding end-of-life care among Korean older adults and the importance of assisting them in planning end-of-life care within a cultural framework.     

Integrating Research Proposals Into a Field Seminar: Feedback From Students

Teaching research to social work students continues to be the topic of an ongoing dialog within the profession. The literature suggests that some form of a “real-world” or “hands-on” learning opportunity has many benefits for teaching a subject that students often are reluctant to engage in. Using online survey methods, researchers gathered feedback from graduate students and their field supervisors about their experience of completing a field seminar that integrated an agency-based research proposal as part of the course requirement. Although there were limitations to this approach, many of the same benefits of actually implementing research were reported by students who completed only a proposal.
