Mechanical graduation thesis 10000 words 1 on mechanical design and automation teaching thinking
Mechanical design and automation is the basic subject of mechanical specialty. Its concept and theory are abstract and its teaching content is complicated. It is difficult to stimulate students' interest in learning with traditional teaching methods. Only by changing the teaching mode and innovating the educational concept can we effectively promote students' learning efficiency and cultivate their thinking ability. This paper discusses several methods to cultivate students' thinking ability from the perspective of optimizing teaching content and innovating teaching mode.
Keywords: mechanical design and its automation; Thinking ability; Cultivation; teaching
Mechanical design ability and manufacturing level reflect the strength of national modernization and are the foundation of national modernization. In the manufacturing process of a machine, parts are its components, and their mutual connection and interaction can make the whole machine play its functions and roles. Mechanical design and automation is an important course in engineering colleges and a basic subject with strong practical ability. Only by learning this course well can we master the basic knowledge of mechanical theory, understand the structure and usage of commonly used mechanical equipment, understand the design principle of parts, and conduct in-depth study and research. Students not only need to master the basic knowledge of general parts design, but also need to carry out corresponding skills training in practice, accumulate certain theoretical knowledge, cultivate correct thinking and ability, and lay a solid foundation for future professional courses and product design.
1 Optimize the teaching content and inspire students' thinking ability.
In traditional teaching practice, teachers adopt? Full house irrigation? Form, regardless of students' feelings, classroom efficiency is low. Adopting heuristic teaching mode and paying attention to students' acceptance and interest in learning can greatly change this situation. Teachers can guide students to actively participate, think, explore and practice by selecting vivid practical cases for analysis and multi-faceted discussion, which will help students to improve their comprehensive ability in an all-round way. Teachers let students form in the discussion through positive guidance? Doubts and disagreements? Question thinking stimulates their interest in knowledge, and then produces the desire for innovation and knowledge. The ultimate goal of education is not only to let students learn knowledge, but more importantly, to let students master the ability and methods to acquire knowledge. It's better to teach people to fish than to teach people to fish. Teachers should pay attention to the cultivation of students' ability, change the education mode according to the characteristics of mechanical engineering, and open students' thinking ability. Deliberately summarize and compare the knowledge in the chapters, and connect the knowledge points into a whole, which is convenient for students to master. At the same time, based on the production technology of mechanical products, closely follow the development trend of modern science and technology, pay attention to the focus and hot spots of the industry, supplement and enrich them, so as to make students interested in exploring new ideas and new things and develop their mechanical innovation ideas.
2. Improve curriculum design to nourish students' thinking ability.
To improve the teaching mode, we must find convenient and accurate methods to improve the teaching efficiency. In the course of mechanical design and automation, there are a lot of complex dynamic and static simulations of mechanical structures and professional knowledge of mechanical movement. Due to the lack of spatial imagination and engineering practice knowledge, it is difficult to learn. Computer-aided teaching software can solve these problems well. By playing pictures, students can be shown the manufacturing process of mechanical parts, the meshing process of gears and even the stress distribution during belt transmission. It completely changed the rigid and frozen state of traditional teaching methods, let students see real, vivid and vivid scenes, enhanced the interest and vitality of classroom teaching, deepened students' cognition, understanding and understanding, broadened students' thinking space and imagination, further expanded students' knowledge capacity, improved the appeal of teaching and significantly increased the effect of classroom learning. Setting questions can stimulate students' curiosity, arouse suspense, promote students' observation and analysis of things and phenomena, and then find ways to explore. The course of mechanical design requires students to master the principle of integrating theory with practice, analyze general equipment and components, be familiar with their working principles and structural characteristics, and cultivate their mechanical design ability. Teachers ask students to use their brains: How do these institutions work? How to determine that the motion mode of the mechanism is unique? How are modern robots designed? These problems have greatly stimulated students to join discussions in their thinking and study actively, which not only changed the boring atmosphere of classroom teaching, but also effectively promoted the deepening of teaching content and achieved good teaching results.
3. Carry out experimental teaching and innovate students' thinking ability.
Experimental teaching is helpful to cultivate students' innovative ability and innovative consciousness, to cultivate students' operational ability of using hands and brains, and to improve students' comprehensive ability. There are many confirmatory experiments in mechanical design and automation specialty, which is not conducive to mobilizing students' active participation, and it is even more impossible to cultivate innovative ability. Therefore, it is necessary to explore various types of experiments, such as basic, comprehensive design and innovative. For ordinary students, focus on cultivating their practical ability, learning ability and problem-solving ability; Students who have spare capacity for learning can further develop their problem-solving ability and innovation ability. Experimental teaching will form an open and multi-level teaching position to meet the needs of different students.
Students can experience the fun of scientific and technological innovation and the methods of scientific discovery in different levels of experimental operation, and have a positive interest in exploration. Teachers should encourage students to design their own experimental contents, practice, use various electromechanical integrated electrical components, creatively design experimental objectives according to their knowledge and combined with mechanical structure design methods, make creative inventions and transformations, and try out innovative electromechanical small products and small motor structures to enhance students' confidence in knowledge and exploration. In the laboratory, students can carefully observe and study the experimental objects, make evaluation and analysis, imitate and reproduce through modeling and design, which is the best environment for students to carry out cognitive practice. The establishment and development of innovative experimental base for mechanical design, and the division, systematization and rationalization of experiments and models are helpful for students to actively design various creative experiments, familiarize themselves with the laboratory environment and make various innovative experimental models.
4 conclusion
"Mechanical design and automation" is an important technical subject. We must constantly explore and improve the teaching content and teaching methods, cultivate students' exploratory thinking and innovative consciousness, enhance students' interest in learning and initiative in practice, develop students' independent thinking ability, lay a solid foundation for their future mechanical design work, and continuously improve students' innovative consciousness and mechanical design ability.
