Research And Implementation Of Interest-oriented STEAM Programming Teaching Aids

In 2019,the Ministry of Education issued the "Key Points of Education Informatization and Network Security Work",which put forward requirements for promoting interdisciplinary teaching,programming education,and artificial intelligence education at the primary and secondary levels.With the promotion of related policies,STEAM education has gradually entered the public's field of vision.More and more education practitioners have gradually realized the importance of STEAM education,hoping that students can learn the knowledge integrated from multiple disciplines in practice,and achieve the educational effect of learning in games and thinking in learning.At present,the relevant STEAM programming teaching aids on the market are not perfect,which limits the development of STEAM education to a certain extent.Taking this as the starting point,this thesis designs a STEAM programming teaching aid that stimulates children's interest in learning and enlightenment of programming ideas.The main tasks of this thesis are as follows:1)An interest-oriented STEAM programming education program for children is proposed.The program embodies the programming language in the form of instruction blocks.Children use the instruction blocks to carry out logical remote control,and carry out different programming controls on the car side,so as to encourage young students to guide the development of programming thinking through their own interests.Experimental tests show that the programming teaching aid can realize interdisciplinary integration in STEAM education,has high playability,and can realize the teaching effect of entertaining and entertaining.2)According to the actual teaching plan requirements,the overall software and hardware framework of the STEAM teaching aids was designed and successfully debugged.The teaching aid is designed as two circuit boards.The control board is divided into four parts:power supply module,main control module,multi-RF scanning and ZigBee communication.The remote control board is divided into four parts:power supply module,main control module,ZigBee communication and motor drive.After determining the device selection,this thesis completes the analysis and design of the schematic diagram and PCB for each part.Write the corresponding logic code for the hardware platform,including the main program flow,motor driver,ZigBee communication program,multi-radio frequency scanning program and mutual communication between modules.The experimental results show that the designed teaching aid can meet the corresponding teaching requirements,realize the scanning of multiple radio frequency tags and control the trolley to move according to instructions.3)Design a new type of multi-radio frequency scanning circuit and a coil antenna that meets the size requirements.The multi-radio frequency scanning circuit combines a radio frequency chip with a radio frequency switch,so that a radio frequency chip can read command information for up to 16 radio frequency tags in sequence.In order to meet the overall size of the teaching aid,this thesis also designed a smaller antenna coil that can stabilize communication,and made a matching circuit design for it.Experimental results show that the designed multi-radio frequency scanning circuit and antenna coil can quickly switch the antenna connected to the radio frequency chip,and can stably read the antenna information.Finally,after testing the overall teaching aids,it can be found that this teaching aid has distinctive features,can achieve the teaching effect of entertaining and entertaining,and meet the original intention of the design.
