1. БHealthБ

One or more systems of the body will change, give rise to БSymptomsБ ( Cough, loose motions, pus formation, headache, fever, breathlessness, vomiting, fits, unconsciousness, inflammation, swelling and general effects - a Doctor look for the basis of symptoms). Diseases are basically two types- Acute Disease & Chronic Disease 3. Acute Disease: The disease which lasts for only a short period of time is called Acute Disease Ex. Common Cold. 4. Chronic Disease: The disease which lasts for long period of time is called Chronic Disease Ex. Tuberculosis. 5. Causes of Diseases : Most of the diseases have many causes, rather than one single cause, like unclean water, nourishment, genetic differences, genetic abnormalities e. g.


Based on the causes diseases are of two types: Non-Infectious Diseases and Infectious Diseases. 6. Non-Infectious Diseases: Not caused by infectious agents, mostly internal and non- infectious cause. Ex. Cancer 7. Infectious Diseases: Caused by infectious agents. (Please refer Fig. 13. 1 (a-e), NCERT Text Book Page- 181). a)The infectious diseases spread by agents are called as Communicable Diseases. It is important that you try to adopt a sequence of questioning that doesnвt end with the right answer. Right answers should be rewarded with follow-up questions that extend the knowledge and provide students with an opportunity to engage with the teacher. You can do this by asking for: a how or a why application of the same skill or logic in a new setting.


Helping students to think more deeply about (and therefore improve the quality of) their answer is a crucial part of your role. The following skills will help students achieve more: Prompting requires appropriate hints to be given в ones that help students develop and improve their answers. You might first choose to say what is right in the answer and then offer information, further questions and other clues. (вSo what would happen if you added a weight to the end of your paper aeroplane? в) Probing is about trying to find out more, helping students to clarify what they are trying to say to improve a disorganised answer or one that is partly right. (вSo what more can you tell me about how this fits together? в) Refocusing is about building on correct answers to link studentsв knowledge to the knowledge that they have previously learnt.


This broadens their understanding. (вWhat you have said is correct, but how does it link with what we were looking at last week in our local environment topic? в) Sequencing questions means asking questions in an order designed to extend thinking. Questions should lead students to summarise, compare, explain or analyse. Prepare questions that stretch students, but do not challenge them so far that they lose the meaning of the questions. (вExplain how you overcame your earlier problem. What difference did that make? What do you think you need to tackle next? в) Listening enables you to not just look for the answer you are expecting, but to alert you to unusual or innovative answers that you may not have expected. It also shows that you value the studentsв thinking and therefore they are more likely to give thoughtful responses.


Such answers could highlight misconceptions that need correcting, or they may show a new approach that you had not considered. (вI hadnвt thought of that. Tell me more about why you think that way. в) As a teacher, you need to ask questions that inspire and challenge if you are to generate interesting and inventive answers from your students. You need to give them time to think and you will be amazed how much your students know and how well you can help them progress their learning. Remember, questioning is not about what the teacher knows, but about what the students know. It is important to remember that you should never answer your own questions! After all, if the students know you will give them the answers after a few seconds of silence, what is their incentive to answer?
