Research On The Usability Of Online Learning Platform For Secondary Vocational Students

Vocational information technology education is to train applied talents with strong computer application ability and work innovation ability.In order to cultivate such talents,students should be encouraged to accept new information and technology and attach importance to autonomous learning.Online learning platform based on MOOC is an important way for learners to learn independently.Vocational school students' demand for the platform is growing.Rapid development makes opportunities and challenges coexist.Improving the usability of the platform's interface can meet the needs of users to acquire information resources,which is an important concern in the design of online learning platform for Vocational Education in the future.In this context,this paper proposes to evaluate the interface usability of MOOC online learning platform for Vocational education.In this paper,based on the relevant research,we use eye movement experiment,usability evaluation scale and subjective satisfaction questionnaire to evaluate the usability from both subjective and objective aspects.It is found that the selected online learning platform has the following interface usability problems,and corresponding suggestions and strategies are put forward to solve these problems: uniform color collocation style,appropriate color,such as homepage,course search,etc.page color should be warmer,use multiple colors to enhance color differences;unreasonable layout,information typesetting should be centralized,but information redundancy should be avoided.With staggered deep and shallow backgrounds,or thick and thin lines,obvious segmentation marks should be set among the plates,and the requirements of vocational education should be met,with emphasis on skill-based teaching blocks.Function setting should not only conform to the basic functions of the network,but also adapt to teaching content and learners' knowledge and experience,and timely updating of functions and maintenance of platforms;interface element design and layout should be carried out in time.In line with people's browsing habits,through the design of different elements such as color,font and so on,we can achieve visual contrast and highlight the key content;if the representation meaning is inappropriate,we should use concise and appropriate words to express the meaning,or beautiful and accurate graphics to express the meaning;lacking of aesthetics and personality,aesthetics is concerned about details while controlling the whole,so that learners can choose and do it independently.Teach students in accordance with their aptitude.It is concluded that secondary vocational school students have the following characteristics when browsing the page: the number of eyes on the head area is about twice that of other areas;the attention of pictures is higher than that of pictures and words;the path of text browsing has a certain direction,but there is no fixed direction for the path of picture browsing;the overall browsing follows the "F" browsing mode.In the future,more new technologies will be used in usability research,and more attention will be paid to the usability research of educational products in the future.
