Physical appearance and peer effects in academic performance

A large literature examines the role of peer effects in shaping student academic outcomes. This article adds to that literature by introducing a new kind of peer effect – the effect of classmate physical appearance. We document that college students are assigned higher grades when in a classroom with peers who are rated as very attractive. This effect is strongest for female students and appears to be concentrated among the courses of younger and male instructors.     

Creating infographics to enhance student engagement and communication in health economics

In this article, the authors discuss and describe the implementation of and lessons learned from a course project centered on the creation of an infographic in a health economics course and an introduction to health research course. Students were asked to create a simple infographic about a particular topic, after researching and gathering data on that topic. The instructors observed how students synthesized information and data to tell a visual story with their infographic. This article adds to the limited literature regarding infographics in undergraduate instruction. An infographic offers faculty an opportunity to apply active learning strategies to enhance student engagement, retention of information, and communication skills.     

Are contingent instructors better teachers: evidence from a Chinese university

This paper evaluates the effects of contingent instructors on education outcomes in the context of higher education in developing countries. Exploiting the features of Chinese higher education system, we are able to exclude the confounding effects of student selection and heterogeneous marking standards. Although students of contingent instructors appear to perform as well as their fellow students taught by full-time instructors, we find the evidence that contingent instructors utilize lower marking standards, resulting an inflation of the scores of their students, which masks the negative impacts of their teaching. Our results suggest that contingent instructors have a significantly negative impact on education outcomes. While exposure to contingent instructors may affect the probability of students taking more challenging courses in the following term, the longer-term impacts on education outcomes are negligible.

Learning to do: Facilitating practice in a large introductory macroeconomics class

Contemporary pedagogy encourages instructors to move away from memorization to teaching the ability to “do economics.” In such an environment, students are taught to apply knowledge of economic measurement, the economic model, and economic policy to analyze current events and policies. In this article, the authors build on existing literature describing independent activities by sharing a set of class exercises and assignments that comprise an entire course. The course discussed in this article is a large enrollment introductory course and presents a novel approach to active learning, adapted to this often-challenging context. The course emphasizes engaging students by encouraging them to practice using macroeconomic tools.     

What is the Comparative Advantage of the Service Learning Pedagogy? Insights from Development Economics

We rely on the Kolb learning cycle and the experiences from two development economics class to analyze the comparative advantage of service learning pedagogy. We hypothesize that service learning is uniquely positioned to improve learning outcomes in applied/policy-oriented specializations. We conceptualize learning outcomes from a discipline-specific perspective where service hours are directly linked to the course content. We argue that the sustainability of service learning in applied/policy-oriented disciplines is limited by journal-entry orthodoxy and short-term costs. Emotive journal entries often encourage an “everything goes” response which threatens the credibility of service learning and limits its use in specializations that value objectivity. Service hours imply costs to faculty and students that exceed those of traditional approaches. This can serve as a disincentive for course adaptation, despite the decline in these costs over time, and enrollment. Our analysis encourages instructors to explore alternatives to the widely used journal-entry and to seek opportunities to inform students of the expected long-run benefit/cost tradeoffs. We encourage administrators to support faculty who teach classes that are predisposed to service learning in ways that can reduce short-run costs. With its comparative advantage and the united efforts across the academy, we expect that in the long-run service experiences will routinely be used to complement traditional lectures in applied/policy-oriented classrooms across the academy.     

Sociability and the Market

This paper addresses two classroom activities for exploring sociability and the role it plays in market and non-market allocations. Adam Smith’s moral sentiments theory provides a conceptual framework for understanding such behavior. In the Desert Island activity students have conversations about competing allocation methods (e.g., rationing, lottery, competition, brute force) that provide a backdrop for learning about market mechanisms and behavioral economics. Beginning students consistently pick egalitarian distributions that signal the implicit willingness to share for reasons that might be instinctual, reputational or other. Fairness in allocations mimics that found in the playing of the Ultimatum Game. The results suggest that economic instructors can successfully bring into the classroom concepts of sociability and the roles it serves in human institutions when introducing a new and different institution—the market.

Let's make a deal in the classroom: Institutional solutions to the Monty Hall Dilemma

The authors describe how the Monty Hall Dilemma, a well-known choice anomaly, can be demonstrated with a simple and versatile classroom experiment. In addition to demonstrating the anomaly, the experiment can be used to introduce students to some institutional modifications that have been shown to ameliorate it. This experiment, which can be tailored by instructors to meet specific learning objectives for a variety of courses, can also be used to frame broader discussions about rationality, institutions, and choices under uncertainty.     

Games superheroes play: Teaching game theory with comic book favorites

The valuable insights of game theory sometimes remain out of reach for students who are overwhelmed by the subject's complexity. Comic book applications of game theory, with superheroes as players, can facilitate enthusiasm and classroom interaction to enhance the learning of game theory. Drawing from content in superhero movies and books, the authors construct games to illustrate pure-strategy Nash equilibrium, Bayes-Nash equilibrium, mixed strategies, sub-game perfection, and perfect Bayesian equilibrium. To help instructors build students' skills in finding and interpreting game solutions, they translate comic book scenarios into specific game forms; however, not all scenarios are obvious so they suggest instructors help students develop their own game-theoretic judgments to determine what game forms, payoffs, and solution concepts might be appropriate for understanding a situation.
