译者藏梦
Science graduate students who did research and teach improved their written research proposals over the course of an academic year more than did grad students who just did research. Steve Mirsky reports. Some graduate students in science, technology, engineering and math—or STEM—only do research, under the guidance of a mentor. Other STEM grad students also have teaching responsibilities, for example, instructing undergrads or local high schoolers. Now a study finds that grad students who also teach show significant improvement in written research proposals, compared with grad students with no teaching requirement. The finding appears in the journal Science. [David Feldon et al, Graduate Students’ Teaching Experiences Improve Their Methodological Research Skills] Researchers followed almost a hundred grad students attending three different institutions. About half of the students also taught. All the grad students were asked to submit written research proposals at the beginning of an academic year and a revised version again at the end. And those grad students who spent the year doing research and teaching showed bigger improvements in coming up with testable hypotheses and in the design of valid experiments. Differences in overall written quality among the students could not account for the results, because only specific skills among those analyzed showed improvement as a function of the teaching experience. So teaching may make STEM grad students better scientists. Not to mention better teachers. --Steve Mirsky
既做研究又从事教学的理科研究生比只从事研究的学生在写研究报告方面更胜一筹。斯蒂夫·米尔斯基报道
一些从事科学、技术、工程和数学（合称“STEM”）的研究生只专注于在导师的指引下做研究。其他的STEM研究生会同时担任教学任务，譬如说，指导本科生或本地高中生。日前一项研究发现，相比之下，从事教学的研究生在撰写研究报告上有着明显的进步。这项研究发表在期刊《科学》上。 [David Feldon et al, Graduate Students’ Teaching Experiences Improve Their Methodological Research Skills]
研究者追踪了在3个不同研究机构的大约100名研究生。其中一半学生兼任教职。所有的研究生都被要求在学年初上交一份研究报告及学年末上交一份修改的版本。那些一个学年即投入研究又投入教学的学生在提出检验性建设和设计有效实验方面表现出更大的进步。
学生间整体写作能力的差异并不会造成这种结果，这些分析中显示出的能力只可能是从教学经验中获得的提升。因此教学也许能让STEM研究生成为更好的科学家，更别说是更好的教师了。
