Research On The Influence Of Indoor Light Environment On Students’ Learning Efficiency

It can be seen that light enters the human eye through the human visual photosensitive system,and biological reaction occurs to control the pupil size,circadian rhythm,etc.of the human eye,which is manifested as having an impact on human physiology and psychology.As the subject of light perception,people must be more people-oriented in the design of light environment in the classroom.Without proper lighting design,students will not be able to carry out their expected activities efficiently and comfortably.For dealing with different types of learning tasks,whether different light environments have an impact on students’ learning behavior and efficiency,and whether students are satisfied with the light conditions in the current learning environment.In view of the above problems,this thesis conducts research from both subjective and objective perspectives,aiming to explore the impact of light environment on students’ learning efficiency,as a theoretical basis for optimizing classroom lighting design.In order to verify the influence of light environment on students’ efficiency,32 students were selected for a 12 day experiment.From the perspective of human factors engineering,through the combination of physics,medicine and psychology,the effects of light environment on human physiology and psychology were fully considered,and the light intensity produced by different time periods and different lighting methods in the classroom was measured,Human factors engineering method is used to test the learning state of the subjects: subjective evaluation questionnaire,behavior and cognition test items,physiological and psychological measurement method designed by measuring mental workload.Subjective questionnaire mainly investigates students’ satisfaction with the current light environment;Cognitive ability test mainly tests subjects’ memory,perception,concentration and logical reasoning ability;Physiological parameters reflect the influence of light environment on students’ physiology by testing the heart rate and blood pressure of subjects.The experiment selected four representative time periods in a day,and set ten working conditions according to the type of light source.SPSS was used to process the experimental data,and the experimental conclusions were obtained.Based on the experimental data,the parameters of students’ satisfaction with the current light environment,the difference of the influence of light environment on handling different types of learning tasks,and the law of the influence of light environment on students’ physiological indicators are obtained.It is concluded that students are more suitable for learning with natural light with uniform brightness distribution within the line of sight and artificial lighting of about 500 lux,and that the increase of illuminance will cause an increase in heart rate but has no significant impact on blood pressure.The impact of light environment on students was quantitatively studied,and the impact of different indoor light environments on students’ efficiency was analyzed.Finally,based on experimental data and human factors engineering theory,reasonable suggestions were put forward for classroom lighting design,which provided a theoretical basis for the study of students’ learning efficiency under different indoor light environments.
