摘要:

計算材料學(xué)系列課程是高校材料專業(yè)的主要課程之一，是介紹關(guān)于材料組成、結(jié)構(gòu)及性質(zhì)的計算機模擬與設(shè)計的課程。通過此課程的學(xué)習(xí)，可使學(xué)習(xí)者了解和掌握材料計算和模擬的基礎(chǔ)知識，進而具備利用計算模擬方法進行材料科學(xué)研究的能力。然而，計算材料學(xué)課程內(nèi)容中包含大量的理論性概念知識，復(fù)雜的數(shù)學(xué)公式、算法和高階的理論推導(dǎo)，采用傳統(tǒng)的單向授課方法，學(xué)習(xí)思考難度大、理解存在偏差，影響學(xué)習(xí)積極性和主動性，導(dǎo)致整體教學(xué)效果差強人意。基于此，開展了基于混合式教學(xué)法的計算材料學(xué)系列課程教學(xué)改革的探索和實踐。通過引入混合式教學(xué)理念，在實際教學(xué)過程中采用線上線下混合教學(xué)、多媒體教學(xué)和虛擬現(xiàn)實技術(shù)等多種方式，不但強調(diào)了教師的“傳授知識”功能，而且實現(xiàn)了學(xué)生作為學(xué)習(xí)主體的角色定位，并將研究性教學(xué)模式引入課堂，引導(dǎo)學(xué)生結(jié)合科研項目去理解、掌握計算材料學(xué)的知識點。實踐證明，這一系列的教改探索取得了初步效果，它有效地把學(xué)習(xí)者的學(xué)習(xí)由淺到深地引向深度學(xué)習(xí)，為高校相關(guān)專業(yè)課堂教學(xué)改革提供了借鑒和參考。

Abstract:

Computational material science is one of the main courses of material majors in college, in which computer simulation and design of materials composition, structure, characteristics are introduced. Through the course, students can understand and master the basic knowledge of material calculation and simulation, and then have the ability to conduct material science research with the aid of computational simulation method. However, the content of computational materials science courses contains a large number of theoretical concepts, complex mathematical formula algorithm and high-order theoretical derivation, traditional teaching method is difficult to grasp the students-attention for a long time, which would lead to difficulties in learning process and finally cause students-enthusiasm decline. The overall effect of teaching and learning would also be unsatisfactory. In order to solve the problem, this paper carries out the exploration and practice of the teaching reform on a series of courses of computational materials science with a hybrid teaching method. By introducing hybrid teaching concept, online and offline hybrid teaching, multimedia teaching, virtual reality technology and various ways are combined in the process of practical teaching, and research-oriented teaching mode is introduced in the classroom, guiding the students to digest and apply the knowledge of computational materials science in scientific research project. The students in class can pay more attention on deep learning, and show more emphasis in learning process. Practice has proved that this series of educational reform exploration has achieved initial results. The teaching reform practice can provide a reference for relevant majors in universities.
