APPRAISAL OF VIDEO CD FOR THE LESSONS

LIFE ORIENTED MATHEMATICS AND GEOMETRY

TERM	SUBJECT	CLASS	UNIT
III	MATHEMATICS	VIII	I

Life Oriented Mathematics

In this chapter the topics are interwoven with Profit, Loss and Simple interest along with formulae. The applications of percentage, profit and loss overhead Expenses, discount and Tax were taught. The formulae for compound interest, simple interest are given.  The difference between compound interest and simple interest is cleanly explained.  Fixed Deposits and Recurring Deposits are also given to get regular practice. People save in this institution at varying rates of interest.  Compound variables direct and indirect variables such as time and work are very essential when we compare the work outputs.

Geometry

In this chapter formation of triangles in different ways are explained. The formats to find the area of a triangle is explained.  In this unit, the concurrent triangles are also explained.

The centre of a triangle, in centre circumcentre of a triangle are also explained with suitable picture.

Pythogorus theorem and the proof of this theorem are also explained in an easy way.  Pythogorean triplets are explained with suitable examples.

Circles:

Definitions of a unit, facts of a circle such as chord. Secant Taught , arc of a circle, segment of a circle, and sector of circle are explained with pictures and definitions to make the children understand easily.

CD PREPARATION AND APPRAISAL PROCESS

          The Text Book contents were converted into Videos and it was displayed to the children in PUMS, V.C.Mottur and PUMS Keeraisathu

S.No	Tool Administrator	Name of the School	No.of Students
1.	Mr.Cholavendhan	PUMS, V.C.Mottur	25
2.	Mr.A.Basheer Ahmed	PUMS Keeraisathu	25

As per the instructions given by Mr.A.Basheer Ahmed, Principal, DIET, Ranipet, the Tool Administrators approached the allotted schools with VCDs and played them to students. Totally 50 children viewed this video lessons along with their teachers.

          At last feedbacks were given by the students and they enjoyed seeing videos in the content.  The meaning of each and every meaning of the hardword has been made understood to the children without the help of the teacher.

FEEDBACK

          Those students watched the above Video Lesson in VIII Mathematics enjoyed the lesson very well.

          The main theme of the lesson is understood to the maximum extent.

          At the end, objective type questions were given to the students to measure their level of learning.   Feedback of the subject teachers about the lesson were also taken into consideration for further modifications and improvement in Video Preparation, Presentation and Content clarity.

APPRAISAL REPORT

·         84% of the children understood that ½ is 50%

·         100% of the children knew that Profit = Selling Price – Cost Price

·         28 % of the children understood that profit % and loss % is always based on the  Cost price.

·         92% of the students shot the answer that Simple interest I = PNR/100 where ‘P’, ‘N’ & ‘R’ are Principal, Time and Rate of Interest.

·         90% of the students understood that amount = P + I , where ‘I’ is the interest and ‘P’ is the Principal.

·         90% of the children viewed the correct answer that If Principal = Rs.7000/- I = Rs.200/- then the Amount is 7200.

·         80% of the students understood that the Cost Price of an object is Rs.200/- and the selling price is Rs.105/- then the discount will be Rs.95/-

·         72% of students knew that the Discount will be Selling Price lesser than the Cost Price.

·         80% of children shot the answer that the tax added to the selling price of an item is called Value Added Tax

·         44% of students understood that the fraction in which 100 is the Denominator is called percentage.

·         78% of children comprehended that the Speed and Distance vary inversely.
