Sunbathe

Vitamin D is one of the most important vitamins, it insures the growth of bones. This vitamin can not be taken by food, it is not found in our diet. Vitamin D can be taken from the sun. The sun is a very important source of vitamin D. It helps our skin to make vitamin D.
The doctor often advises people, especially the children to sunbathe (to bask under the sun).
But be careful! Do not expose yourself to the sun for a long time to avoid sunburns.
To avoid sunburn you should use sun protection also you should drink large amounts of water to nourish your kin.

Vitamin Sea

I feel comfortable when I spend several ours in front the sea, observing the sun set and hearing the sounds of waves. Those work like vitamins. They enrich my organs and refresh my soul.

Educational Technology: Does It Improve Academic Achievement?

Educational Technology can empower teachers and learners, promote change and foster the development of twenty-first century skills. Improving education quality is a priority for most developing countries in which governments are facing a challenge to identify efficient ways to use their scarce resources and raise the quality of education.

Many studies show that the effective use of technology does not only improve academic achievement but also increases students attitudes and self-concepts toward learning. 

Moreover using technology can enhance the student information age skills and increase students motivation.  

The role of teacher in 21st century.

In the 21st century the teacher has a multi tasks to finish. The role of teacher is not restricted in teaching only, the teachers roles are much wider than what we can imagine. The teacher is : 

1. The Controller: The teacher is in complete charge of the class, what students do, what they say and how they say it. 

2. The Prompter: The teacher encourages students to participate and makes suggestions about how students may proceed in an activity. The teacher should be helping students only when necessary.

3. The Resource: The teacher is a kind of walking resource center ready to offer help if needed, or provide learners with whatever language they lack when performing communicative activities. The teacher must make her/himself available so that learners can consult her/him when (and only when) it is absolutely necessary.

4. The Assessor: The teacher assumes this role to see how well students are performing or how well they performed. Feedback and correction is organized and carried out.

5. The Organizer: Perhaps the most difficult and important role the teacher has to play. The success of many activities depends on good organization and on the students knowing exactly what they are to do next. Giving instructions is vital in this role as well as setting up activities.

6. The Participant: This role improves the atmosphere in the class when the teacher takes part in an activity. However, the teacher takes a risk of dominating the activity when performing it.

7. The Tutor: The teacher acts as a coach when students are involved in project work or self-study. The teacher provides advice and guidance and helps students clarify ideas and limit tasks.

Teaching Biology by using Jigsaw

 Biology is a very interesting subject to teach. During teaching biology we can use different strategies such as cooperative learning. Jig saw is a very important strategy that you can use in order to make biology easier. In ten steps you can apply the learner centered methods.

Divide students into 5- or 6-person jigsaw groups. The groups should be diverse in terms of gender, ethnicity, race, and ability. 2. Appoint one student from each group as the leader. Initially, this person should be the most mature student in the group. 3. Divide the day's lesson into 5-6 segments. For example, if you want history students to learn about Eleanor Roosevelt, you might divide a short biography of her into stand-alone segments on: (1) Her childhood, (2) Her family life with Franklin and their children, (3) Her life after Franklin contracted polio, (4) Her work in the White House as First Lady, and (5) Her life and work after Franklin's death. 4. Assign each student to learn one segment, making sure students have direct access only to their own segment. 5. Give students time to read over their segment at least twice and become familiar with it. There is no need for them to memorize it. 6. Form temporary "expert groups" by having one student from each jigsaw group join other students assigned to the same segment. Give students in these expert groups time to discuss the main points of their segment and to rehearse the presentations they will make to their jigsaw group. 7. Bring the students back into their jigsaw groups. 8. Ask each student to present her or his segment to the group. Encourage others in the group to ask questions for clarification. 9. Float from group to group, observing the process. If any group is having trouble (e.g., a member is dominating or disruptive), make an appropriate intervention. Eventually, it's best for the group leader to handle this task. Leaders can be trained by whispering an instruction on how to intervene, until the leader gets the hang of it. 10. At the end of the session, give a quiz on the material so that students quickly come to realize that these sessions are not just fun and games but really count.

   

Teachers make all other proffessions possible.

A good teacher is like a candle. It consumes it-self to light the way for others. It

is very hard and difficult to be a good teacher. I think to be a good teacher is to help the students to know the secrets of the world. It means to bring them a lot of knowledge.

A good teacher is like a candle because the teacher is that person who do the minds of

their students more brightly. It means that the teacher gives the information which the student's didn’t know and point them the right way in their lives. Every teacher consume itself to light the way to others.
