| The audience response system (ARS) has increasingly been used to engage students by eliciting and analyzing responses to questions posed by instructors. The authors discuss how they used the system to facilitate pit market trading in a microeconomics class, report the efficacy of the approach and provide suggestions extending the use of ARS to other experiments. Using the ARS to facilitate active learning by engaging students in economics experiments has pedagogical advantages over both the labor-intensive approach of pencil-and-paper and the capital-intensive route of relying on networked or on-line computer labs which oftentimes preclude or restrict face-to-face student interactions. Thus, the new method represents an added advantage on top of such... |

| On the strength of the theory of agricultural circular economy, the mutual relation between the development of agricultural circular economy and new village construction is analyzed. The results show that developing agricultural circular economy and constructing new village is the mutual promotion; realizing agricultural circular economy is the main aim of new agricultural construction and developing agricultural circular economy is the way of realizing new village construction. The major problems in the development of agricultural circular economy in Qinhuangdao City are pointed out, covering weak ideological foundation of developing agricultural circular economy; inadequate directions from the government and insufficient technical and financial support.... |

| The authors discuss how they used the audience response system (ARS) to facilitate pit market trading in an applied microeconomics class and report the efficacy of the approach. Using the ARS to facilitate active learning by engaging students in economics experiments has pedagogical advantages over both the labor-intensive approach of pencil-and-paper and the capital-intensive route of relying on networked or on-line computer labs which oftentimes preclude or restrict face-to-face student interactions. Thus, the new method of conducting experiments represents an added advantage on top of such conventional functions as taking attendance and administering quizzes of this increasingly popular classroom technology. |

| About 10% of primary school students in developing countries have poor vision, yet in virtually all of these countries very few children wear glasses. There has been almost no research on the impact of poor vision on school performance in developing countries, and simple OLS estimates are likely to be biased because students who study more often are likely to develop poor vision faster. This paper presents results from the first year of a randomized trial in Western China that began in the summer of 2004. The trial involves over 19,000 students in 165 schools in two counties of Gansu province. The schools were randomly divided (at the township level) into 103 schools that received eyeglasses (for students in grades 3-5) and 62 schools that served as... |

| About 10% of primary school students in developing countries have poor vision, but very few of them wear glasses. Almost no research examines the impact of poor vision on school performance, and simple OLS estimates are likely to be biased because studying harder often adversely affect one’s vision. This paper presents results from a randomized trial in Western China that offered free eyeglasses to 1,528 rural primary school students. The results indicate that wearing eyeglasses for one year increased average test scores of students with poor vision by 0.15 to 0.22 standard deviations, equivalent to the learning acquired from an additional 0.33-0.50 years of schooling, and that the benefits are greater for under-performing students. A simple cost-benefit... |
