基于材料工程专业学生认知心理学的《实验设计与数据处理》的教学探索

Teaching Exploration on “Experimental Design and Data Process” Based on Cognitive Psychology of Students

《实验设计与数据处理》课程是在高等数学,概率论以及材料加工工程相关专业课程学习的基础上开设的,涉及的实验设计方法和数学公式较多,各章节相互独立又紧密联系。由于各自基础不同,材料加工专业学生学习《实验设计与数据处理》课程的效果差异较大,不能形成系统性认知,不能将课本讲授的试验设计方法在铸造工程实践中自如运用,数据的整理和处理不能满足工程本身的需要。通过对学生这些问题的研究和分析,对《实验设计与数据处理》课程提出了基于认知心理学的教学策略,包括遵循信息输入规律,提高学生对知识点的理解能力;综合运用认知心理学各种方法,提高学生学习效率和学习效果;提高学生专注程度,延缓形成认知疲劳,有效改善课堂认知效果;注重教学引导,强化学生对信息的选择,储存。

The course"Experiment Design and Data Process"is set up based on high mathematics,probability,and materials process engineering-elated professional courses,In the course,experimental design methods and many mathematical formulas are involved and each chapiter is independent,also closely connected.Because of different basic knowledges,the students,who learning material process technology,have different learning results and cannot form a systematic cognitive,cannot apply the experimental design method freely in engineering practice,their ability of data sorting and processing cannot meet the needs of the foundry project.Through analyzing and studying these issues,for the course"Experiment Design and Data Process"teaching strategies based on cognitive psychology are put forward including follow the basic information input rules and improve students’comprehensive understanding ability for knowledge points;comprehensively using various methods psychology to improve their learning efficiency and effectiveness,improve their attention points,delay cognitive fatigue and improve cognitive effect;focus on the teaching guide and strengthen information selection and storage.
