    Does Downloading PowerPoint Slides Before the Lecture Lead to Better Student Achievement?: Reply

    Full text link
    This reply responds to a comment by Cannon (2011) that opens the debate on consistency of the effect of downloading PowerPoint slides before lectures on students’ exam performance. Cannon (2011) points out potential endogeneity problems in Chen and Lin (2008) and attempts to explore the unconditional mean effect of downloading PowerPoint slides for the full sample. In this reply, we firstly argue that the estimates in our original article are consistent since the effect of interest is the “conditional†treatment effect but not the unconditional mean effect. We provide explanations for our rationale of estimating the “conditional†treatment effect. Secondly, we propose a modified downloading variable to replicate Cannon’s analysis. Our results suggest that downloading PowerPoint slides before the exam does not produce a significant effect on absent students’ exam performance which is different from the results in Cannon (2011). Our analysis does support Cannon’s argument that students fixed effects are different across different attendance status.

    An investigation of Fang-ming Chen\ue2s discourses on nation and liberalism

    After the end of martial law in late 1980s, the political discourse by Fang-ming Chen, one of the proponents of Taiwan\ue2s nation building, has been taken as an indicator among Taiwan\ue2s Pan- green group. While Chen has self-reported as an liberalist, how could he remains a die hard nationalist? How did he deal with the contradiction between liberalism and nationalism? Or the declaration and practice are two different things. This thesis departs from the statement that Chen is a classic liberalist, follows, as well as does detailed reading of the content of his personal life, observes the ingredients of liberalism which have been instilled into his life to cultivate his thought of liberalism. This thesis also explores Chen\ue2s level of liberalism. Is it a deep belief, or just a mean of power struggling? The author deeply believe that as a belief, liberalism is a goal deserved for seeking without regrets, while as a mean, liberalism is disposable. To examine the essence of Chen\ue2s thought of liberalism, the author puts emphasis on analyzing Chen\ue2s discourses on Taiwan nation, Taiwan independence, transitional justice as well as Cross-Strait relations. The relation between Chen\ue2s related political discourses and his perspective of classic liberalism is intriguing. Even though Dworkin\ue2s take of liberalism stresses precarious republicanism, public will and positive liberty rather than individual liberty, will and negative liberty, scholars still regard him as a liberalist according to his way of discussion, not the nature of the object. Since Chen is neither a constructor nor an assistant of theory of liberalism, for the author to prove or disprove Chen\ue2s stand of liberalism is to examine his discourses and practice. Is Chen become more of liberalism or less of it? From the spirit of liberalism, any construction should be examined by time, including the author\ue2s argument. Whether Chen could become a liberalist as declared by himself has become the battle inside him
