Research On The Teaching Effect Of Physics Experiment Based On Arduino

Current research on robot education focuses on the learning of robot ontology knowledge,such as robot programming,robot construction or mechatronics.With the rise of STEM interdisciplinary education concepts,people have begun to explore the application of robots in other disciplines.Taking physics as an example,research and practice have shown that robots can be used as experimental means to explore physical concepts and laws.However,compared with traditional physics experiments,robot-based physics experiment teaching has its own specific advantages,and there is still no relevant research.To this end,this study used a quasi-experimental research method to carry out a round-study experiment,and the research object is 36 senior high school students who take the robotic course in the 13th Middle School in Nanjing.These 36 students were randomly divided into 2 classes:Class A and Class B,each class is 18 people.Arduino open source software and hardware were used as teaching equipment during the research.Before the experiment,all students' robot learning foundation and physics knowledge base were tested to confirm that they have the same starting point level.Then two rounds of experiments were carried out.In the first round of experiments,Class A carried out traditional physics experiments,Class B carried out physics experiments based on Arduino.And the second round was reversed.After each round of experiments,post-test was conducted to collect the data of students' physics performance,learning attitude,learning engagement and cognitive load.Through experimental data analysis,this study draws three conclusions:(1)The experimental sequence and experimental type do not have a significant impact on students' physical performance,learning attitude and learning engagement,but have a significant impact on students' cognitive load.The cognitive load of students who do physics experiments based on Arduino and then do traditional physics experiments is significantly higher than that of students who do traditional physics experiments and then do physics experiments based on Arduino.This may be because students are more familiar with traditional physics experiments,and the Arduino robot is more unfamiliar to students,from familiar to unfamiliar,compared with the unfamiliar to familiar,the cognitive load of students will be correspondingly lower;(2)the gender of students and experimental type do not have a significant impact on students' physical performance,learning attitude,learning engagement and cognitive load;(3)the type of experiment does not have a significant impact on students' physical performance,learning attitude,learning engagement and cognitive load.According to the research conclusions,the performance of Arduino open source software and hardware in physics experiments is not outstanding compared with the equipment of traditional physics experiments.Although the teaching effect of the physics experiment based on Arduino is not significantly better than the traditional physics experiment,it achieves the teaching effect equivalent to the traditional physics experiment.Compared with traditional physics experiments,Arduino-based physics experiments are more unfamiliar to students and require longer adaptation time.Increasing the experimental period may further enhance the advantages of Arduino-based physics experiments.In addition,the physics experiment tasks used in this experiment are relatively easy and may affect the experimental results.Therefore,it is necessary to further explore in the follow-up study.
