Chemical Education Higher Education Modern Education Technology Chemical Industry W Sticking Practice Yue Xuehai Wang Xiaohong Zheng Jianguang Zhao Wen Zhou Chuanguang (Qingdao University of Science and Technology, Qingdao 266042, Shandong, China) Based on the combination of scientific research achievements and teaching experience. Using the multimedia authoring tool Flash 4.5, the CAI courseware for course design of chemical engineering was designed and developed. The courseware integrates the use of images, presentations, sounds, and texts to teach students so that they have a strong sense of materiality.
Principles of Chemical Engineering; Course Design; CAI System Software With the development of computer technology as the core of modern information technology into the field of education, colleges and universities should popularize basic computer education in various subjects and improve education and teaching quality. Computer-assisted instruction should be adopted to fully implement teaching. Modernization of technological means.
The study of the computer-assisted teaching system as a major part of the teaching reform of the Principles of Chemical Engineering has increasingly revealed its importance and necessity.
First, the characteristics of chemical engineering curriculum design characteristics of chemical engineering curriculum design is the integrated application of chemical engineering principles and related pre-requisites knowledge, complete the unit operation as the main design practice. Through this link, students can master the basic procedures and methods of chemical design, and obtain basic engineering practice training in accessing technical data, selecting formulas and calculation methods, and using simple words and diagrams to express design results and drafting capabilities.
Principles of chemical engineering courses are generally scheduled to be completed in 2 weeks. Each teacher should teach 1-2 classes at the same time. There is very little teaching time evenly distributed to each student, and it is difficult to provide students with individual guidance in a timely manner. In addition, the design process has a large amount of calculations. Under normal circumstances, students can only conduct confirmative design under the given conditions of the instructor. The design scheme and parameters involved often rely on experience, making it difficult to compare programs and technical and economic calculations, and students’ synthesis. The lack of practical training in engineering design capabilities has also affected the function of the course of chemical engineering curriculum design in cultivating engineering students' innovative ability and engineering accomplishment.
Second, the necessity and significance of research and development In order to improve the teaching quality of chemical engineering curriculum design, and effectively play its engineering practice education function, we have developed a set of theoretical knowledge learning and typical unit design two major functions in one chemical Principle Course Design CAI system.
The use of this system has effectively provided teachers with lesson preparation assistance, freed the teacher from a large number of repetitive and detailed instructional tasks for individual students, and was able to concentrate on the deepening of teaching content; increased the number of teachers to supervise students, and adapt The trend of improving the ratio of students to teachers advocated by the reform of higher education has increased the autonomy of the students' learning process, which is conducive to the exertion of the subjective initiative of the students and better embodies the individualized teaching ideas of "teaching according to their aptitude"; The ability to obtain actual physical data compensates for the deficiencies in the disengagement of engineering from the idealization of physical data processing in students' theoretical teaching; it also promotes the computer application ability of chemical engineering students and promotes the progress of professional quality education. It embodies the level of computer application ability training and improves the curriculum system to avoid the repetition of computer knowledge learning during learning.
CAI course design of chemical engineering principle course is the National College Teaching Research Association and the National College Teaching Research Center Yue Xuehai (1971-), Male, Lecturer, Master, Educational Administration Section chief; Wang Xiaohong (1968-), female, associate professor, master; Zheng Jianguang (1978-), male, bachelor; Zhao Wen (1954-), male, professor, PhD, Dean of the School of Chemical Engineering; Zhou Chuanguang (1958-), male , Professor, Ph.D., Vice President.
A software development subproject for the development and practice planning of CAI courseware for the course of chemical engineering curriculum design and the project "Study on Computer-aided Instructional System of Chemical Engineering".
CAI Courseware for Chemical Engineering Course Design adopts a multimedia composite structure.
The main function of the chemical engineering curriculum design is the use of computer multimedia technology (such as video, animation, sound, pictures, etc.) to explain the internal structure of various chemical equipment, the role of principle, gas liquid, liquid, gas-solid, liquid-solid Interaction process and various operating conditions, supplemented by equipment design calculations.
The entire courseware highlighted the interactive features and "moving" features. Under the auspicious music accompaniment begins with the prologue animation music, the courseware enters the interactive interface, and uses different controls to realize the conversion, return, sound and presentation between the various contents.
1. The navigation catalogue was designed rationally, emphasizing the level of knowledge of the courseware, so that students can freely choose the learning content when operating the courseware.
2. The learning coaching module uses sound, animation, graphics, music and other media means to express the teaching content of the chemical engineering curriculum design and provides students with a vivid and vivid three-dimensional teaching environment.
3. The equipment design module provides students with practical examples to train students in the design of Chemical Engineering Principles.
text. The commentary for each page in the courseware is displayed on the page in text form. Because the speed of reading text on a computer screen is slower than reading a text in a book form, the text content of each page cannot be too large, the word is relatively concise, and the font that is easy to read is selected. This courseware uses a variety of fonts such as Song and Lishu. In order to increase the contrast, different colors are used in different texts. Text production is through Microsoft Word2000 for entry, typesetting, proofreading, using the OLE technology in Flash, the text content is embedded in a new display image file. Background music. All background music is selected from the music library of the CAI course system. According to the content of the performance, choose a relaxed, gentle music as background music. bitmap. The bitmap in the courseware is created using a special tool software Photoshop 6.0 or acquired by a scanner. Most animation animations are referenced from some material libraries.
Learning coaching module. Use Flash to process the interface with software such as FoundrySoundForge. After editing, save as fla file and click debug video in the window menu. After success, save as swf file. Equipment design module. The device design module uses the Borland C++ programming language to program according to the selected cell device and the best algorithm. By selecting the menu or different options in the dialog for compiling and linking options, the compiler/connector generates the corresponding OBJ file and EXE file. The program can be shipped.
In the C++ environment, edit the main program, set the call swf and fla program to achieve the integration of the entire courseware. Afterwards, it is compiled and packaged to form a CAI courseware for chemical engineering course design that runs in Windows 9x and Windows 200 environments.
Fourth, the installation and operation of courseware The courseware installation is very simple, just the chemical engineering course design CAI courseware CD into the drive, you can automatically run into the software installation interface.
Click Welcome! You can enter the documentation about the introduction of the software; click Install to enter the installation process; click Exit to exit the installation of the software. After the installation is complete, run Run.exe in the corresponding location to enter the software system.
