An Academic Program Profile: Wayne State University

Since 1948, the Learning Design and Technology (LDT) program at Wayne State University has been offering degrees. Presently, the LDT program offers PhD, EdD, master's, and undergraduate degrees and two certificates. The degrees are delivered using various methods including face‐to‐face, blended, and online. The program focuses on the application of learning sciences and relevant disciplines to improve performance in organizations. The program has two concentration tracks: design and performance systems and learning technologies. Four full‐time and seven adjunct faculty are engaged in various research initiatives and projects with funding in excess of $5 million total. The faculty members serve in leadership roles in several academic and professional associations. In terms of programmatic initiatives, the LDT faculty members have renovated their programs to help make sure students can complete all required courses in 2 years, and the PhD in 4 years. They also are initiating a full‐time research intensive program. With capable faculty members and an excellent curriculum, the LDT program at Wayne State University nurtures competent scholars and professionals. —Sung “Pil” Kang, Ph.D. and Yeol Huh, Ph.D. column editors     

Teaching Social Justice Research to Undergraduate Students in Puerto Rico: Using Personal Experiences to Inform Research

This article explores the process of teaching undergraduate students to conduct social justice research. We were interested in understanding how to develop a social justice perspective among students while training them in conventional research methods. The following questions guided our research activities. How can the principles of social justice inform undergraduate research projects? What pedagogical strategies prepare students to conduct social justice-based research? What are the challenges and opportunities in teaching social justice research? We documented the lessons and activities during the field school and collected students’ comments in journals, extensive observations, focus groups, and interviews to understand the influence of social justice on the students’ approach to research. We identify three lessons in teaching social justice. First, teaching social justice requires that students develop meaningful relationships with the community understudy. Second, gender dynamics can prohibit or promote meaningful student engagement and learning. Third, it is important to consider how to integrate, rather than “add on,” social justice activities and discussions into research lessons.

CIRLab: A groupware framework for collaborative information retrieval research

In this paper we describe the design of a groupware framework, CIRLab, for experimenting with collaborative information retrieval (CIR) techniques in different search scenarios. This framework has been designed applying design patterns and an object-oriented middleware platform to maximize its reusability and adaptability in new contexts with a minimum of programming efforts. Our collaborative search application comprises three main modules: the Core, which supports various modern state-of-the-art CIR techniques that can be reused or extended in a distributed collaborative environment; the Facades Mediator, an event-driven notification service which allows easy integration between the Core and front-end applications; and finally, the Actions Tracker, which allows researchers to perform experiments on the different elements involved in the collaborative search sessions. The applying of this framework is illustrated through the analysis of the collaborative search-driven development case study.     

How to play the “Names Game”: Patent retrieval comparing different heuristics

Patent statistics represent a critical tool for scholars, statisticians and policy makers interested in innovation and intellectual property rights. Many analyses are based on heterogeneous methods delineating the inventors’ or firms’ patent portfolios without questioning the quality of the method employed. We assess different heuristics in order to provide a robust solution to automatically retrieve inventors in large patent datasets (PATSTAT). The solution we propose reduces the usual errors by 50% and casts doubts on the reliability of statistical indicators and micro-econometric results based on common matching procedures. Guidelines for researchers, TTOs, firms, venture capitalists and policy makers likely to implement a names game or to comment on results based on a names game are also provided.     

Key Competencies Required of Performance Improvement Professionals

Despite the growing literature about the criticality of a performance focus in our field, the literature on empirically formulated competencies for performance improvement professionals reflecting this shift has been scarce (Dean, 1999). While this study was being conducted (2000–2001), there were no formally recognized standards to guide performance improvement professionals. What the literature did offer was standards for instructional designers, specifically, the International Board of Standards for Training, Performance and Instruction (IBSTPI) released the third edition of Instructional Design Competencies: The Standards (Ritchey et al., 2000). Around this same time, The International Society for Performance Improvement (ISPI) was simultaneously, and independently, working on developing such standards. This study pursued similar efforts through two overarching purposes. The first purpose was to identify competencies required of competent performance improvement professionals. While previous studies had generally addressed what constitutes ideal practice, no data had been collected on current practice. Thus, the second purpose was to determine how often performance improvement practitioners believed they (1) should be, and (2) are currently applying each of the identified competencies. The relationships and gaps between these two indicators were also examined.     

Planning a responsive evaluation: Establishing solid partnerships by clarifying expectations and purpose,part 2

For evaluation to be worth the resources it consumes, it must enable decision makers to make sound decisions based on relevant, reliable, and valid data that lead to improved performance. It is from here that all evaluation efforts stem. All components of the evaluation must be aligned with the objectives and expectations that the organization and its stakeholders value and the decisions that will have to be made as a result of the evaluation findings. These decisions should be concerned with how to measurably improve performance at all levels of the organization. This article, the second of a two‐part series on evaluation (see Guerra‐López, 2007b, for part 1), describes how to create a responsive evaluation through the identification of stakeholders and expectations as a first and fundamental step.     

Analysis of the distances covered and technical actions performed by professional tennis players during official matches

The purpose of this study was to analyse the physical and technical performances of professional tennis players during official matches. The trajectories of eight players were obtained during matches, using an automatic tracking method. The distances covered and technical performances were analysed for the first and second sets. The athletes covered (mean ± standard deviation) a total of 1702.4 ± 448.2 m in the first set, 1457.6 ± 678.1 m in the second set and 3160.0 ± 880.1 in the entire match. No differences were found between the sets for the physical variables (lateral and forward displacements, distance covered per rally, per game and per set, and the percentage of time spent in each range of velocity). However, the distances covered by the athletes during the rallies in which they were serving (median = 5.2; interquartile range (IQR) = 6.7 m) were statistically smaller than when they were returning (median = 6.2; IQR = 7.7 m). Forehand ground stroke proficiency decreased from the first (mean ± standard deviation: 75.2 ± 4.11%) to the second set (mean ± standard deviation = 65.5 ± 14.3%). In conclusion, tennis players did not present reduced physical performance from the first to the second set.     

Ethnicity,social class,and perception of hyperactivity

This paper examines the relationship between ethnicity and hyperactivity, an area largely neglected in research on hyperactivity. The assumption that hyperactivity is uniformly distributed across ethnic groups is challenged, based on a large (N = 1719) sample of white, black, and Mexican-American elementary school children. The Abbreviated Conners Teacher Rating Scale was used to identify the hyperactive group. Two important findings emerged. First, the 15% overall incidence rate is substantially higher than previously reported in the literature for large samples. Second, in those schools with nonwhite majorities, teachers rated black children as significantly more often hyperactive and Mexican-American children as significantly less often hyperactive than would be expected, based on their representation in the general student body. These findings are interpreted from a sociological perspective.
