Benefits Of Computer-assisted Instruction

Computer-based instruction and educational activities have been a part of high school level curricula for some time, but the primary grades have adopted these techniques a little slower. However, the adoption of technological learning activities will increase sharply over the next few years. Experts disagree on the single most important driving factor, but there are clearly a number of distinct advantages to computer-based learning activities over more traditional educational activities. Here are five of the most important.

The pace of instruction concerns everyone involved in the development of educational activities. Parents often worry about their child being either left behind or held back by the performance of the other students in the classroom. Teachers using traditional learning activities have trouble progressing some of the students in a classroom if not all are ready. Computer-based educational activities assist here by allowing each student to learn at his or her own pace. One student can move onto more demanding educational activities before the rest of the class without disrupting anyone else’s learning. Simultaneously, another student can repeat certain learning activities as often as advisable.

Computer-based instruction can also enhance the relevance and quality of educational activities. This will often register as a prime concern for parents and students. Collaborating with an appropriate site for learning activities will provide the school district or classroom teacher with a wealth of choices. With educational activities organized by grade level and covering a vast array of subject material, a valuable partnering site will empower the instructor with the ability to choose learning activities to target the students’ needs best. Further, if the site includes authoring tools, the teacher or parent may create new educational activities to address any under-served curricular areas. Additionally, a user community, if offered, may enable the sharing of learning activities far more easily than before. Providing instruction on the computer then helps foster increased relevance for the lessons involved.

To compete in today’s society, students need to achieve a much higher level of comfort and ease with technological tools. Today’s primary age students will find computers and technology dominating their workplaces to a greater degree than their parents or perhaps even their older siblings. Another advantage of learning activities on computers for our children then is that it teaches on multiple levels. Our students not only master the curriculum materials embedded in the learning activities, but also become more adept at using computers, which is also of value to them.

Finally, computer-based instruction can help lower the cost of our kids’ educational activities. Instead of buying multiple copies of a textbook for each subject matter area, schools can invest in computers and software to attend to all students. Many sites for learning activities can be accessed for a modest monthly fee. This one fee can then address an entire classroom’s needs across many curriculum areas at once, and therefore provide an economical way to provide educational activities. For these reasons, classrooms will feature computer-based instruction going forward.

Are You Suffering From Computer Stress

Sadly, grandma wouldnt have a remedy for this particular ailment. Computer stress is a relatively new term, which has been coined considering the negative impact the over usage of computer, has on our mental and physical health.

Almost everyone gets stiff shoulder, neck and back while working for long hours in front of the screen. And that is just the physical aspect of computer stress, do you have an unclear memory and find it hard to concentrate after a few minute? Ever got really mad and jabbed keys on the keyboard just because your screen wouldnt load fast?

Our incessantly increasing dependency on technology in general and computers in particular, has made it to be a huge part of our lives today. This is why sometime losing data through hard disk crashing or even slow internet connection can take a toll on our stress level and create a feeling of frustration and anger inside us.

Some common symptoms of Computer Stress:
Dry eyes, redness and irritation
Persisting headache
Fatigue and tiredness
Stiff shoulder and neck
Regular back ache
Pain in arm and wrist
Irritability
Absent mindedness
Lack of concentration

A lot of us professionally depend a lot on technology, whether it is storing data or communication. Shutdown or data wipeout is bound to affect out professional life and our physical and mental health. Heres what you can do to prevent and combat computer stress:

Figure out your problems- Is it your data you are most worried about or your internet connection conking off? Figure out what can cause you maximum computer stress and try to look for alternatives. Get a backup of your data in a pen drive and keep a dongle or charm your neighbor to give you their wifi password so that you can use them in times of emergency.

Befriend some tech nerds- If you are anything like me and are truly baffled by the nuances of technology; befriend someone who is good at it. Having a friend or a colleague who can guide you through difficult situations will help in getting solutions to problems in a short span.

Buy decent products- No, you need not go running out and buy a Macbook Pro (although, theres no guarantee of it running flawlessly), but always try to get branded products that would put up. A lot of us compromise on quality to get products cheaper, instead of buying inferior quality goods, see if you can get a deal or a discount.

Relax- We know that things can get difficult and frustrating, but try to keep your calm. Stressing out would only make matters worse, try to look for alternatives and relax.

Organize your work station- Ensure that your computer desk and chair are angled properly or if you work on a laptop, use a laptop table so that you do not slouch while working.

Take breaks in between, stretch yourself and splash some water on your face and especially in your eyes.
