Research on the effectiveness of foreign multimedia-assisted teaching
[Abstract Multimedia-assisted teaching is widely used around the world. While improving students' academic performance, it also faces
< p>Many problems caused by improper use. This article analyzes and introduces the theory of foreign media-assisted teaching, effectiveness experiments of multimedia-assisted teachingresearch, effectiveness principles and application trends.

Education reform, especially the update of teaching technology and related teaching methods
Changes are generally carried out in accordance with the norms of "theoretical demonstration - practical pilot
-
summary - promotion". As a teaching tool, media has always played an important role in the teaching process. The use and update of media are usually strictly operated in accordance with the above specifications. However, the use and popularization of
multimedia tools based on
computer systems in the teaching process does not seem to have time and space for educational operations
The author gives more room for thinking. Before many theoretical and practical principles
are clear, as an unprecedented new technology that affects the entire social life of mankind, multimedia has become an important player in the teaching process in an instant
p>
has become a very important role. But with the popularization of use,
more and more problems have been exposed, such as: What is the most reasonable role positioning of multimedia in the teaching process
? How does it relate to students' learning achievements?
How big is the correlation between them? Is it necessary
or what restrictive principles are needed during its use? Some researchers have gone further
Pay close attention to its compatibility with the personality characteristics of teachers and students, its compatibility with
subject teaching, its compatibility with the teaching environment, etc. Blind
use of multimedia may not achieve the desired results, and may even make
teaching fall into forms of "redundant information competition" and "mechanical activities"
< p>quagmire. Therefore, it is of great practical significance to analyze and explore these issuesfrom both theoretical and practical aspects.

Theoretical disputes about media-assisted teaching
Since multimedia enters the teaching process in a "use it first and discuss it later" manner, in
In the past few years of its use, controversy over its teaching effectiveness has never ceased
. Opponents and supporters have their own opinions, but neither can produce absolutely convincing inferences and evidence. But multimedia is also a kind of media, but it just highlights the comprehensive characteristics. The basic principles of use and efficiency should also follow the basic rules of media use. Therefore, the theoretical controversy over media-assisted teaching over the years actually represents a theoretical controversy over multimedia-assisted teaching.
In the past 10 years or so, whether the media will have an impact on learning
and what kind of impact it will have has been an issue of endless debate
. The vast majority of people have a positive opinion on the value of media use in the learning process, but opponents also try to state and verify their own opinions. Among them, Clark , 1983)’s view is the most representative. Clark believes that because it is difficult to conduct an experiment in which factors are strictly controlled, the effects of media demonstrated in many studies are uncertain and questionable, and the effects are likely to be caused by Caused by other variables in the experiment that are not related to the media
. He made an interesting analogy to illustrate the inability of the media in delivering teaching guidance. The role of the media in teaching is "no greater than that of a truck carrying groceries." It can cause huge changes in our physique." l1
However, the views represented by Clark did not gain wider support
but triggered more media teaching support theories
The focus of this debate has gradually shifted from whether to use media in teaching to how to use media effectively.
Supporters of media-assisted teaching mainly analyze the role and role of media in the teaching process from the perspective of environmental cognition theory
. The perspective of "environmentalism" originated from the research of Vygotsky, Gibson and Dewey
. Vygotsky believed that the environment plays a conditional role in the development of individuals, and people must learn in practical organizations, which is the basic prerequisite for learning. Changes in the social environment directly trigger the development of human individuals, and media is one of the environmental factors. [21 Dewey believes that individual
cognition is carried out in the social context in which learning occurs, and the environment or
media constitutes the peripheral environmental conditions of learning, stimulating or hindering people's development

Exhibition. One of the important functions of the environment is to stimulate individuals' participation in social activities
.
At the same time, individuals are related to other people within social media, and the connections between people are the basis for understanding the social environment. [3 Gibson believes that perception is completely dependent on the interaction between people and the environment. The environment serves as a vehicle that facilitates or constrains individual activities. People and the environment
are integrated, and people cannot be studied independently of the environment. [41
Later researchers also specifically explored the characteristics of Gibson's so-called "information carrier". For example, Greenough (1994) believed that cognition has >The process is the interaction between the agent and other systems, and the environment
can also be regarded as an agent, so it can be maintained and influenced by adjusting the environment
Cognitive activities. Just like driving a car, the driver determines the direction and conveys his intentions through the steering wheel, and the tires are the carrier that ensures movement in the correct direction. Therefore, the carrier is one of the prerequisites for behavior. l5 Lemke (1997) made an overall review of the ecological social system model and believed that the understanding of the environment should not be divided into its original components as factors. Analysis should focus more
on processes and practices. Organizational components such as people and technology cannot be separated from
the environment. They can only be regarded as environmental participants.
