Metaphor——A Tool for Writing

Figurative speeches, especially metaphors that prevail essays, novels, reports, poems, etc. give flavor, if not life, to writings, help express the inexpressible, bring the abstract concrete, make the tedious succinct, and illuminate the vague and the ambiguous bright and clear. It seems that metaphors to writing is what salt to cooking ─ and more. In this paper, we are attempting to drag it to a "down-to-earth" tool to be handy to common learners by quoting examples from various styles to show how it can be used to increase language power and how important it is for ordinary Chinese learners of English to get familiar with and learn to employ metaphors and other figurative speeches in writing. We should be able to use words in non-literal sense to lend force to an idea, to heighten effects, or to create atmosphere, so as to make our writings eligible at least for practical use and readable for an ordinary native speaker of English.

Exit cards: creating a dialogue for continuous evaluation

This study explored the use of Exit Cards, which are formative evaluations of student knowledge and instruction undertaken at every class meeting. Its results are based on Exit Card data from two undergraduate research methods courses. Thematic analysis indicated that students used Exit Cards to communicate (1) what they learned, (2) challenges with course material, (3) experiences with peers, (4) requests for help, (5) challenges with coping, and (6) successes. While the present study is an initial exploration of the use of Exit Cards, it contributes to knowledge on the utilization of informal formative assessments.
