MASTERY LEARNING IN FRICTION

This sequence of mastery exercises has been prepared to demonstrate Mastery Learning to the Papua New Guinea Department of Education.

So much nonsense has been written about this strategy that it is time to demonstrate beyond all doubt. The inventor of Mastery Learning intended breaking skills down from basics to the higher level skills.

But some fool teachers in the United States removed the basics and increased research. They called it Outcome Based Education and blamed Bloom for its failure.

Bloom was in his 50s when he introduced Mastery Learning and in his 80s when OBE came in. Why blame him? He died at the age of 94 years.

Mastery Learning was intended to pass the slower students and lift high the more capable students. It was a response to the US Government paranoia on the Russians sending up the satellite Sputnik.

Already modules have been prepared in Literacy and Biology. In the media there has been a report from the Department of Education that the new curriculum will not be ready for the new year. Please click:

MASTERY LEARNING IN SCIENCE

Modules in Mastery Learning in English, Biology, Science, Personal Development and Mathematics could be ready for validation within 10 weeks. Please click:

WORK PROGRAM FOR GRADE 10

The sequence in Friction below consists of 40 small mastery exercises approprate for primary school students supported and guided by the teachers. All have a common theme of friction. Solving one problem provides the key to the next problem and so on.

This module in friction could be submitted to a design team of science teachers who might be able to add 30 more exercises. The sequences could be rearranged and added to from the class room.

Some problems may be easily solved by students. But they may not have thought of the issue in that way.

Problems that are interesting could be given more focus by teacher and students. They may not have thought of electricity generated by blood passing through the blood system. Then they learn that sharks can detect this electric pulses from fish and swimmers.

They may not have thought that the world depends on friction. Without friction, we could not walk, climb or run. Cars could not run. Pulleys could not work.

We start with the real situations and explain what is happening. Then we work out the theory behind the scenarios. This is INDUCTIVE LEARNING. There is no focus on theory as we see in classes today.

What happens when we rub our hands together?

Explain how villagers make fires with sticks.

Feel the tires of a car that has been driven a long way.
What do you feel?

What happens to moving cars if we pour oil on the road?

When do most moving cars have accidents?

Why do many cars have accidents on a bend in the road?

How do we light a match?

Is it better to light a match on a match box or a window?

How do we stop the hinges on doors from sticking and squeaking?

How do we keep the engine of a car cool and running smoothly?

Why do we have to change the oil in an engine?

Why are there crackling noises when we comb our hair?

Do we hear the noises on a hot dry day or a cool wet day?

Cut paper into pieces. Rub a plastic ruler in cloth and place
on the papers. What happens? Which cloth is best?

Why does black dust gather on a ceiling fan?

Why do pieces of paper above become electrified?

What are the best boots to wear on the Kokoda Track?

Why are there grooves on the rubber sole?

What happens to our hands when we slide quickly down a rope?

If we wear shoes for many months, what happens to the soles?

What causes electricity in our bodies?

Sharks detect electricity in fish. What causes electricity in fish
and other animals?

How do we know there is electricity in our bodies?

Why do car tyres lose their rubber?

Why do some tyres lose the rubber quickly?

What is the best to slide on - rock? water? coral? or mud?

What is friction?

What occurs when there is friction?

Give examples of friction causing heat?

How do we reduce friction between pieces of
steel rubbed together?

What would happen in the world if there was no physical friction?

What happens when an engine seizes?

How does friction occur between people?

What causes friction between people and animals?

What happens to the temperature of the relationship when friction occurs?

How do we remove friction between people?

Advanced problems in friction

What is constipation?

How does an enema work?

What effect does fibre have on waste in the large intestine?

Why does an asteroid trail fire on entering the earth's atmosphere?

What is the main problem facing space shuttles returning to earth?

What is a friction rash?

How do we treat a friction rash?

What causes an aircraft to lift off on take-off?

How does a violin player make sound?

These problems explore all possible aspects of friction. This is an exercise in exploration of the practical scenarios.

Students learn general knowledge as well as knowledge of friction. They learn to explain in their own words, written and spoken.

Students could be interviewed one at a time at the teacher's table on 5 problems. Most students in PNG schools never speak.

It is not just effort in mindlessly copying theory into a student's work book as we see in PNG schools today. Please click:

EDUCATION IS NOT EDUCATION IN PNG

By the end of 2013, this sequence in friction could have 80 more exercises provided by class room teachers, students and design team teachers. The Department would develop a memory bank of exercises.

Teachers could be invited to submit their new exercises to the design team to be included in the next edition. Teachers are becoming involved.

The mastery sequences could be arranged in modules. Science may have 20 modules for all grades. Elementary grades complete module 1. Grades 3-4 complete modules 1 to 5. Grades 5-6 complete modules 1-9....and so on.

Grade 5 students could revise the earlier exercises of modules 1-4 in the first 3 weeks of the term....and so on. 

There is always revision. As students grow intellectually, they will see all earlier problems in more complex ways and with more connections.

We already see in the exercises above the links with static electricity, motion, physiology and personal relationships. 

By end of grade 8, some students should be able to achieve 100% correct of the (say) 1200 science and biology mastery exercises. One book said 60% correct 60% of the time. Students can do better than that.
