本研究之目的在於為工職英文課本建構一套理論與實證兼顧的評估準則，並對工職學生的語言需求與期望作深入的探討。 評估準則建立在以下五個基礎之上。 (1) 工職英文教與學之現況 (2) 溝通式語言教學 (Communicative Language Teaching)的原理與原則 (3) 專業英文(English for Specific Purposes)的概念與議題 (4) 現有的教材評估準則 (5) 工職學生之語言需求與期望分析 為了解學生對英文的需求與期望，問卷調查與訪談成為此研究之重要部份，涵蓋了有： (1) 針對217位工職舉業生進行需求調查，以了解工業界使用英文的實際情形與溝通需求。 (2) 針對645位工職學生進行期望調查，以了解學生對英語教學的期望。 (3) 訪談5位工職畢業生、6位工廠主管，以了解工業界使用英文的詳細情形；訪談5位四技二專畢業生，以了解學生在進入四技二專後，使用英文的情形；訪談6位英文老師及3位工業英文教師，以了解英文及工業英文教學之概況。 本研究根據問卷調查與訪談的資料深入探討與分析了學生對英文的需求與期望，並對教育當局及編書者多所建議。分析結果並加以整合並融入根據理論及文獻探討所初步擬訂的教科書評量表中，以期能確實有效評估工職教科書。為使評量表發揮最大功用，本研究還設計了彈性的評分方式，並提供了使用方面的建議，希望對英文教師在選擇教科書時能有所助益。 / The purpose of the present study is twofold － to formulate a theory-and-survey based evaluation scheme for IVHS English textbooks, and to give an insight of IVHS students' language needs and wants. The evaluation scheme has been established on considerations of: (1) the current IVHS teaching/learning situation (2) general guidelines of communicative language teaching (CLT) (3) notions and issues of English for specific purposes (ESP) (4) evaluation schemes and criteria already proposed by other researchers (5) an analysis ofIVHS students' needs and wants To inquire into students' needs and wants, surveys and interviews have been conducted, including: (1) A needs survey on 217 IVHS graduates for the actual use of English and communicative needs in industries. (2) A wants survey on 645 IVHS students for their expectations toward an IVHS English textbook. (3) Interviews with 5 IVHS graduates, 6 factory supervisors, 5 technical college graduates, 6 English teachers, and 3 Industrial English' teachers for the situation and episodes requiring English in industries, academic use of English, and classroom use of textbooks. The present study faithfully reports on IVHS students' language needs and wants, along with some other suggestions for textbook writers and authorities concerned. Incorporating the findings from surveys and interviews, the evaluation scheme proposed is thus rooted on both theoretical and practical grounds. To ensure optimum usage of the scheme, its scoring system is devised to be flexible and its application is further provided.
