【摘要】：文章針對課堂知識量多、結(jié)構(gòu)分散容易導(dǎo)致大學(xué)生認(rèn)知負荷過高而影響學(xué)習(xí)效果的問題,基于大腦信息加工原理、信息編碼過程和信息多維屬性,建立了大學(xué)生認(rèn)知負荷結(jié)構(gòu)和知識獲取過程,分析了基于多維屬性的知識類型與設(shè)計元素映射關(guān)系,以及降低認(rèn)知負荷的知識可視化步驟及方法。研究發(fā)現(xiàn):(1)大學(xué)生的認(rèn)知負荷結(jié)構(gòu)包括以認(rèn)知能力為主的內(nèi)在負荷、以經(jīng)驗行為為主的相關(guān)負荷以及任務(wù)、信息和設(shè)計負荷融合的外在負荷;(2)知識可視化過程涉及分解多維屬性、劃分結(jié)構(gòu)特征、分析可視性和創(chuàng)建交互性;(3)多媒體中的顏色、紋理、透明度、形狀、布局、方位和位置等可視化元素,主要通過對覺察、分辨、理解、獲取和預(yù)測能力的調(diào)節(jié),降低認(rèn)知負荷。
[Abstract]:This paper aims at the problem that the students' cognitive load is too high and the learning effect is affected by the large amount of classroom knowledge and the scattered structure, based on the principle of brain information processing, the information coding process and the multidimensional attributes of information.The cognitive load structure and knowledge acquisition process of college students are established, and the mapping relationship between knowledge types and design elements based on multidimensional attributes is analyzed, as well as the steps and methods of knowledge visualization to reduce cognitive load.The study found that the cognitive load structure of college students includes the internal load based on cognitive ability, the related load and task based on experiential behavior.The process of knowledge visualization involves the decomposition of multidimensional attributes, the division of structural features, the analysis of visibility and the creation of interactivity / 3) the color, texture, transparency, shape and layout of multimedia.The visual elements, such as orientation and position, reduce the cognitive load by adjusting the ability of perception, resolution, understanding, acquisition and prediction.
