In the last article, we have talked about the benefits of the laser projector, now we??d like mentioned something you must care about when purchasing the laser projector.
There are many models to be optional on the market and each one counter different prices. You may get confused why some models are cheaper or more expensive, how do you choose. Here, I want to advise two key points for you:
The different chip will totally counter different prices, 0.47 DMD with great prices but maybe not perform very well in brightness, test result shows it can achieve at most 1200-1600lum. Another disadvantage of 0.47chips is it not suitable for big screen, it may occur color fading in size like 100inch. The latest DLP technology used in the projector now is 0.65DMD, which have much improved in both problems.
2.Fewer laser, lower prices.
You may also notice that laser source has a pure laser and hybrid laser. Pure laser working structure is: Laser source with phosphors to create light as following picture shows.
For hybrid source, working structure is: LED source+ Laser source+ Phosphors. One benefit of the hybrid is saving cost.
Use the hybrid source, it may emerge three questions:
2.1 Hybrid SSI(ReD +Laser or Red/Blue+Laser)will generate imbalance question due to different color source.
2.2 Due to the large light-emitting angle of the LED, the light-emitting angle relative to the laser light source is small, and the optical system can not collect more light energy to increase the brightness by increasing the number of LEDs, it will cause hybrid source with bad light collection efficiency, on account of this, it will reversely result in hybrid projector in high brightness mode must sacrifice color balance, if choose the color balance mode must sacrifice brightness, it will only 1500 lum.
2.3 Hybrid source (LED & Laser) efficiency decay trend inconsistent, long-term use will result in can not maintain color balance, will also affect the lifetime of the projector.
So many benefits of laser projector as I mentioned, but it still not popular in the market,why??In other words, What??s its disadvantage?That??s relatively expensive compared with traditional lamp projector, So how much will it cost for laser projector?The price will vary due to different chip and the laser source, different configuration required depends on your needs.Another solution for this disadvantage is IQ projector with 0.65DMD, pure laser projector are in end-year promotion, you can get this product with best prices ever,if you’re interested, don??t lose this opportunity.
Any market to accept new products will take time, the thing we can do is to go ahead than others, or we will leave behind by them.Lasers provide unparalleled superiorities, there is no doubt that laser projector would be the future of the projectors!
In addition to being highly knowledgeable in the subject matter, teachers also need to know how to manage classroom dynamics effectively. This entails organizational and disciplinary skills that both help make different types of classroom interactions more systematic and aligned with the learning objectives. Otherwise, classes that are conducted by teachers with very minimal classroom management skills tend to produce less favorable outcomes, such as low student achievements. Some studies, in fact, suggest that when teachers are inefficient at managing disruptive classroom behavior, the average pace of cognitive development among all students suffer greatly.
If you happen to handle classes where disruptive behavior is present, then there are classroom management techniques that you can implement to reduce or even eliminate disruptive classroom behavior. This article presents two solutions–one a process and the other a set of methodologies–that you can use in various combinations depending on the learning conditions in each of your classes.
Class Management Process
This set of steps aim to transform the classroom environment into one that actively encourages learning. By modifying both the physical and human aspects of the classroom, teachers will be able to establish an ecosystem that has a positive atmosphere and one that compels everyone to attain learning goals.
Have a plan.Nothing beats a comprehensive strategy for achieving learning goals. Each learning session must follow a pre-planned outline that details 1) the expected learning outcomes; 2) how the teacher is to introduce, demonstrate, or explain a lesson or subject matter; 3) the techniques by which the teacher will motivate the class to actively participate in the learning process; 4) how the students will participate; and 5) the alternative strategies in case the actual learning outcomes and student behavior are not what has been expected.
Establish the best learning climate possible.Excluding human factor, the overall learning conditions in any classroom can be modified readily. How a room looks and feels have a direct impact on learning. Lighting can be configured depending on the teaching purpose, for example (well-lit rooms facilitate clear reception of all sensations especially those that are visual while a darkened room magnify sound sensations and may be good for articulating pronunciations, and other verbal concepts; a spotlight focuses students’ attention to a particular learning stimulus such as the teaching conducting a lecture, a visual image, or the whiteboard.). Get rid of disruptive background noise (a faulty electric fan or air conditioning unit, for example) whenever possible. Clutter and other visual pollution that unnecessarily divert people’s attention should also be addressed.
Conduct class sessions efficiently.Clarify the goals you want your students to achieve and the ways by which they can achieve them. Never appear to be disorganized to your students. Be consistent in order to set an example and establish a clear system for different classroom activities.
Practice authority positively.Develop mutual respect but integrate wholesome humor in your interactions. This will allow you to reach out to all your students and to avoid neglecting anyone. Maintain a positive and accessible demeanor so that your students will be encouraged to communicate. Practice the so-called three F’s required of successful educators: firmness, fairness, and friendliness.
Class Management Techniques
Managing student behavior is critical to the success of your teaching sessions. You can use any of the following techniques in order to establish the right learning attitude among your students.
Subject Focus.Everyone in your class should be primed for learning before you introduce a new subject matter. When students are engaged in chatter that is unrelated to the subject matter or appears to be doing something not related to the lesson, don’t continue your teaching until you get their full attention. Temporarily stop discussing the subject matter whenever you think students are not paying attention since that would be a waste of time and effort. Otherwise, opting to teach even when students are not paying attention will establish the notion that it is okay to be rude and to ignore someone speaking to you.
Modelling.For the learning process to be healthy and effective, teachers need to establish their leadership and authority inside the classroom. They also need to exhibit the very traits they want their students to develop and possess. As role models, teachers should know and practice how to show respect and concern for others so that students can emulate their actions. In addition, teachers should show decisiveness and fairness in order to establish a good, disciplined environment for learning.
Proximity and Modality.Students tend to be more involved when teachers are at arm’s length compared to when they are more distant. This is because people tend to do whatever they want to give the chance to do so. In a classroom setting, students in locations that are farthest from the teacher are likely to do their own thing and misbehave compared to those who are in close proximity to the teacher. To address this issue, move across the room during lectures or seatwork as much as possible. Equally, engage as many students as possible and make it clear that you confer due attention to everyone and care about their learning achievements.
Reward System.Teachers should understand what motivates students and use these as platforms for cognitive development. Human needs such as a sense of belonging and affirmation can be used for further nurturing good classroom behavior. Also called “Positive Discipline” by some educators, this technique showcases positive traits instead of calling students’ attention to bad behavior. Praise and reward often accompany this technique and are used to reinforce everyone’s preference for good behavior.
Regular and Random Aptitude Assessments.To check whether students are learning as much as expected, teachers should give regular tests in the form of announced exams, seat works, group activities, and other assignments such as random concept checking. Unannounced quizzes should also be regularly given not only to monitor students’ progress but also to compel students to consistently pay attention in order not to fail in the surprise quizzes.
Lesson Management.The teacher’s understanding of people’s motives and behavior is just one side of the coin. The other side concerns teachers themselves. The fact is, while it is assumed that teachers know their subject areas adequately, sharing their knowledge is another matter. Due preparation and planning are necessary to conduct each learning session successfully.
Teaching is a rewarding profession and is critical in preparing the next generation of people for meeting the challenges of tomorrow. It can also be a highly stressful discipline especially for new teachers who are easily intimidated by adverse classroom dynamics. These guidelines should be able to help teachers streamline their classroom engagement strategies in order to yield positive outcomes–both for them and their students.
The invention of new technologies and the update of old educational devices showed no signs of slowdown in 2017. Sophisticated teachers will want to make sure they have all the latest trends and innovations so that their students can learning under the best technology.
Most of the recent trends are expected to continue into the classroom. From cheap whiteboard to better interactive device operating systems, educators should know what will happen in 2017.
Technology in the Classroom
The number of devices and uses for tech in the classroom has been steadily increasing over the years. According to a recent survey of 2,500 educators, 60% of teachers expect to use more technology in the classroom than in the past this current school year.
Over the years, the amount of equipment and technology used in the classroom has steadily increased. According to a recent survey of educators, most of the teachers want to use the latest technology in class than they used to.
Three-quarters said they used a technology in class every day, and 80% said technology was positive in the classroom.
The most popular technologies used in the classroom are small laptops and tablets. Apple iPads is adopted by many schools due to their simple interface and touch screen. Related apps can make young students learning initiative.
In recent years, the pad has become a classroom device due to its low cost, various hardware options, and a simple Web-based operating system. These small pads also give educators control over student activity and can be preprogrammed with educational applications. Students can use the pad to collaborate and collaborate with groups from spreadsheets and documents. Those devices are especially useful in schools where limited equipment and internet access is available in the student’s home.
Teachers have also adopted IQBoard in class. These computer-connected digital whiteboards use projectors and fingers, enable up to 10 students to write on the surface. Teachers can explain a concept on the board and annotate the important part by built-in software.This is a great tool for students of all ages and a few subjects.
Some educators are trying to be virtual or augmented reality. Students can enter the 3D location using high-end technology such as Google Glass or the low-end Google Cardboard VR helmet. History students can visit distant locations with free apps or use the New York Times New York software to explore current events. The cost of cardboard headphones is less than $ 10, using a free application that requires only a smartphone.
Using technology in the classroom dates back nearly 100 years when airwaves began broadcasting air lessons. Since then, innovations such as ultra-short throw projectors, calculators, desktops and CD-Roms have revolutionized the teaching environment.
IQ is committed to providing different intelligent education programs for schools with different requirements.
Projectors are one of the few inventions that form the basis of a truly solid technology-based classroom. Projector – that projects magnified text or images onto the screen to make the classroom more colorful and resourceful, and improve the teaching quality.
Projectors have proven to be one of the best technologies for educators ever since. Educators can enhance students’ retention of the information they presented by showing powerpoint files, multimedia, videos and similar content. The projector mainly uses two technologies, DLP (digital light processing) and LCD (liquid crystal display).
DLP projectors project images by reflecting hundreds of tiny mirrors (called digital micro-devices, each representing one pixel). DLP projectors are easier to handle because of their smaller size and lighter weight. DLP projectors project better images than competing LCD projectors because they are all-digital and higher contrast.
An LCD projector operates by beaming light via transparent LCD cells. It technology splits light into three polysilicon panels, one each for the red, blue and green. Images on the bigger screen are produced by the blend of light beaming through the LCD cells. Both, DLP projector and LCD projector, have the potential to engage tech-savvy students in a dynamic and immersive way by delivering multi-dimensional curriculum to a large class with astonishing image quality.
The LCD projector operates by irradiating light through a transparent LCD unit. The technology breaks down the light into three polysilicon panels, one each in red, blue and green. The image on the larger screen is generated by a mixture of light beams passing through the LCD unit. Whether it is a DLP projector or a liquid crystal projector, it is possible to attract skilled students in a dynamic and immersive way by offering multi-dimensional lessons to large classes with stunning image quality.
It is useful when an LCD or DLP projector can magnify an image and project it on a large screen or surface when it comes to a large audience. With the help of the projector, the teacher’s book can be read by all the students present at once. Make larger images on the screen or other flat surfaces with DLP projectors or LCD projectors to make it easier for students to read and master text or other material, even in the back of the classroom.
A projector can be used to display a small map or places on the map, such as states, capitals, islands etc, in close details. Classrooms designed around DLP/LCD projectors can bring subjects to life by integrating text, audio, graphics and motion videos. Furthermore, students gain an opportunity to experience interactive simulations, internet excursions and digital imaging-based presentations and much more.
IQProjector is interactive DLP laser projector which delivers superior image quality and performance.Ultra short throw lens,0.6m projection distance creates a large area at 100 inches, super suitable for classroom or meeting room.
Interactive whiteboard, use a personal computer or laptop as a medium to perform the required functions. Recently, many school teachers have begun to use these whiteboards to encourage interactive learning in their classrooms. The basic process of operating these interactive whiteboards is simple, which is why many teachers decide to use them as aids in the classroom. People of all ages can take advantage of these whiteboards when they need to present themselves in front of a large audience. Teachers need a lot of creativity in their daily teaching. The availability of these interactive whiteboards enables them to design more effective and efficient ways to teach students the knowledge they need. This will help teachers grasp and retain students’ attention and students will be able to understand the concepts being taught more clearly.
People in different fields and industries have begun to use interactive whiteboards to create people’s awareness of the different things that happen in their surroundings. Around the usage of these whiteboards, organized a number of seminars and lectures. Training courses can also be done in a better way by using these whiteboards. Meetings for planning and targeting are easy to conduct when using these whiteboards to create presentations and display charts and diagrams that illustrate what you need to achieve in a particular time frame of the future.
There are many interactive whiteboards that can be found on the market such as ultrasound optical whiteboards, electromagnetic whiteboards, digital whiteboards, resistive whiteboards and infrared whiteboards. The type of materials and equipment required for the proper operation of each type of whiteboard may vary. The materials used to make these whiteboards will also be a prominent factor in the way these whiteboards are named. Different devices will be used to send and receive signals from these whiteboards. In order to operate each type of whiteboard, different types of equipment will also be used.
A lot of people belonging to different professions have understood the advantages of making use of these different whiteboards. All the activities which can be performed using the normal whiteboard can be done using these interactive whiteboards. Some of these whiteboards will contain programs which have inbuilt software which will help in recognizing different kinds of handwriting. This will enable the whiteboard to write freely on the whiteboard.
Many people of different occupations understand the benefits of using these different whiteboards. All activities that can be performed using a regular whiteboard. Some of these whiteboards will include programs with built-in software that will help identify different kinds of handwriting.

Its quite exhilarating for IQ members to come and see snow as there rarely snows in the south area of China, especially for Fuzhou city where our headquarter locates. Therefore, IQs going to visit one of the world cultural heritages-Huangshan Mountain-as our destination for annual group travel 2017. Get ready for the snowing world.
At the first day, we were heading for Huangshan Mountain. Even at the foot theres falling snow already. Knowing that the temperature would be much lower than that of downtown, everyone was wrapped up to keep warmer.
Guess whether our little boy reached the summit or not with such heavy coat.
The journey began with a long slope called as Hero Hill. And yes we are all heroes after climbing up the hill.
Then we were attracted by the famous landmark of Guest-Greeting Pine which stretches out from a cliff to welcome visitors from all over the world.
Could you find it in the picture below
Though its not easy to walk downstairs by clinging to the rope, we were not held back and taking care of each other to finish the trip.
Its tiring but meaningful. Along the journey was full of laughter.
Wrote down IQ to give direction for the way ahead.
And this is IQ team spirit.
The beautiful scenery and smiling faces.
The next sunny day we paid the visit to the local towns.
Time flew by and travel came to the end. Here are some lovely pictures behind the scenes . Come have a look.
Was it more attractive to view from such a strange angle
