Research And Design Of Mobile Audio Learning Products For Declarative Knowledge Courses

With the popularity of mobile terminals,mobile learning has developed rapidly.The knowledge media of mobile learning include graphics,audio,video and other forms.Audio has become an important medium for knowledge dissemination due to its accompanying and highly infectious characteristics.The type of knowledge transmitted by audio is dominated by declarative knowledge.At the same time,due to the characteristics of single-channel linear display of audio,mobile audio learning users are prone to problems such as difficulty in flexibly controlling the learning rhythm,low knowledge absorption efficiency,and difficulty in knowledge precipitation after learning.In terms of practical application,the current online mobile audio learning platform pays more attention to the content discovery before learning and the exploration of content payment,and there is less exploration in improving the efficiency and quality of mobile audio learning,and there is no relatively complete solution.In terms of theoretical research,there is a lack of relevant design research in the field of mobile audio learning.Most of the existing research has carried out research from the perspectives of communication and marketing,and few researches have been carried out on mobile audio learning products from the perspective of design.Based on this background.This paper chooses to research and design mobile audio learning products for declarative knowledge courses,in order to solve the problems of poor learning effect and difficult knowledge accumulation caused by audio linear single-channel display,and improve the learning experience and learning efficiency of mobile audio learning users.And complement the design research gap in the field of mobile audio learning.First,through literature research,the author clarifies the current research status of mobile audio learning at home and abroad as well as related theories such as mobile learning,cognitive load,deep learning,and grounded theory,and provides theoretical support for subsequent research and design.After that,the basic behaviors and habits of mobile audio learning users were learned through questionnaires,and then based on the grounded theory research method,the original information was collected through in-depth interviews,and the information was coded at three levels,and the audio learning motivation-audio learning behavior-audio was constructed from the bottom up.A mobile audio learning behavioral model for learning quality.And based on this model,it traverses user requirements,transforms requirements and functions,and determines design definitions.After that,the design practice is carried out and the design schemes of key functions are screened through control experiments,and the high-quality schemes are further optimized according to the post-experiment interviews and experimental results.At the same time,it conducts voice interaction design and gesture interaction experimental research on basic audio control functions,and produces a complete voice interaction solution covering voice assistant,corpus,dialogue script,interaction process,and feedback interface,and a set of standard gesture actions.Finally,a detailed design plan to improve the mobile audio learning experience and efficiency is produced.The main research results are:(1)Based on grounded theory,a threelayer mobile audio learning behavior model of audio learning motivationaudio learning behavior-audio learning quality is constructed from the bottom up to provide theoretical guidance for related product design research;(2)Through Control experiments are carried out to evaluate the design schemes of 5 key functions to improve the efficiency of mobile audio learning,screen out high-quality schemes,and optimize the scheme according to the experimental results and post-experiment user interviews.(3)Conducted experimental research on voice interaction design and gesture interaction for basic audio control functions(such as play/pause,fast forward/backward,etc.),and produced a voice interaction scheme and a set of standard input gesture sets.(4)Produced a complete plan for mobile audio learning in three stages:before class-during class-after class,to provide reference for the design practice of similar products.
