In the past two years, interactive whiteboards have shown great growth not only in education but also in the commercial market. E-commerce, large-scale exhibitions and events have been incorporated into the interactive whiteboard application jurisdiction.
The key factor in the popularity of interactive whiteboards is their interactivity.
The whiteboard relies on the powerful communication capabilities of the computer and its own interactive technology annotations, which allows users to freely mobilize resources directly in the panel, and can project the display content in the computer through the projector, which is the popular base of the whiteboard---electronics The whiteboard can directly operate the computer file and the program system through the whiteboard interface.
In the teaching activities, the quality of the electronic whiteboard affects the quality of teaching to a certain extent. At present, the research on the combination of interactive whiteboard and specific subject has achieved certain results. For example, interactive whiteboard can raise questions, analyze problems, prove the topic and divergence proof in geometric teaching; use the writing function of electronic whiteboard, different learning Those who can write and mark with different colors of pens can form personalized learning, learn from each other's strengths, and make progress together. The design of the interactive whiteboard in the classroom is based on the constructivist learning theory, embodying the status of “teacher-led, student-centeredâ€, situational creation, group cooperation, and display of group results to maximize the teaching effect.
At present, interactive whiteboards have been widely used in teaching, but there are still some problems in the specific application process.
1. At the school level, there is a lack of incentive mechanism to promote teachers' use of new media;
Second, at the teacher level, some people have a misunderstanding of this new type of teaching media, and the relevant operational skills are not fully grasped. Therefore, when teaching design, its function can not be played well;
Third, from the perspective of students, the lack of appropriate operational skills, can not be a good teacher-student interaction;
Secondly, on the hardware level, this new type of teaching media is more expensive, requires high hardware and is expensive to build. The whiteboard is affected by the environment and light, and is easy to reflect, which causes students to experience visual fatigue and disadvantages students' learning. Also at the software level On the other hand, there are few personalized resource pools, teachers are prepared to prepare for classes, and so on. There is still much room for improvement and development.
From the perspective of the overall application effectiveness, domestic interactive electronic whiteboards tend to be mainly subject-oriented in the research and application process; in terms of recommendation, they focus on function introduction and advantage analysis, and lack of in-depth system analysis. On the contrary, we should carry out this deeper and more detailed research and development of this new teaching medium, and push its application to other subjects, use different functions to stimulate learners' interest in learning, and promote individual self-learning and independent thinking. To pave the way for building a lifelong learning society.
As the name suggests, the Sit Stand Desk is a table that can be raised and lowered, so the lifting function is the biggest feature of this Height Adjustable Table. The lifting column is up and down through the control of the control box. Therefore, the most important part of an Electric Adjustable Desk is the lifting column (including the motor), the control box, and the hand controller. Without one of these three parts, the lifting function cannot be realized. The two lifting columns of the Dual Motor Standing Desk are controlled by two motors, and the stability and fluency of the dual-motors are more prominent among similar products.
