NAME OF THE SCHOOL: KENDRIYA VIDYALAYA, KANNUR
NAME OF THE TEACHER: VENUGOPALAN.P.E, TGT (Maths)
SUBJECT: MATHEMATICS
TOPIC CHOSEN: MEASURES OF CENTRAL TENDENCIES. (STATISTICS)
CLASS: X
1.TITLE OF THE PROJECT: Health status
of KV Kannur students in Upper Primary (Classes VI to VIII)
2. OBJECTIVES:
1. To identify the
underweight/overweight students in upper primary classes (Class VI to VIII) by
comparing the findings with standard data.
2. Explore the possibility of research to find the reasons
for undernourishment, if any, in the findings.
3. Examine the performance of undernourished students, if
any, in academics.
3. PROJECT OUTLINE: The Class XA students are
divided in to 12 subgroups. Each group has to collect the data (and share the
collected data) of height/weight of girls and boys of classes VIABC, VIIABC and
VIIIABC and perform the tasks entrusted to each group. The findings of each
group will be consolidated and a final report will be presented for each class
4. PROJECT REPORT
1 DEFINE PHASE.
1) Selection of Topic: The students of class 10 learn to
calculate the measures of central tendencies in class 10 statistics. To connect
the learning outcome to the practical life situation the project is planned as
an activity for FA4. The project is integrated with
Science and English language and the computer science and technology with
internet. T
2) Outcome: It is expected that the students
collect the relevant data from an available source and classify the data
according to the need of the task assigned. They are instructed to calculate
the mean, median and mode of a specific group for a specific data. Then they
were asked to compare the data with the standard data available in the
internet. They are expected to arrive at a definite conclusion of their task
question?
3) Scope: the scope of the project is multidimensional.
At this dimension the students are asked to find out the mean, median and mode
of the grouped data. Then the observed data is compared with the standard data
and find out the underweight students of classes VIABC,VIIABC and VIIIABC. The next dimension is to find
out the reasons for under nourishment if any. Then the third dimensions is to
find out if the health status of the students of VI,VII,VIII is directly
connected with their academic performance. The fourth dimension is to check at
teacher level to link the findings for planning the EQUIP programme of Upper
primary students.
4) Links to curricula: The topic is a direct application of
the learning outcome of the chapter Measures of central tendencies of grouped
data in Class Mathematics. It is integrated with health science by connecting
with BMI chart which they learn in science and social science. It connected to information
science and technology as the children are asked to collect the standard data
from internet. It is connected to computer software as they are asked to
prepare a height weight chart for comparison. They can download BMI calculator
or prepare a Height Weight Chart in MS Excel.
5) Strategy: A selected group of students work in
groups. Collect data, share the data collected, help each other to complete the
tasks thereby enhancing peer group learning to achieve the objective of the group
which is labeled as Task group. The group work also intended to develop
leadership qualities.
6) Assessment Approach:
The assessment of the group work is planned based on the following tasks
and materials prepared related to each
a) Collection of data ( list of students
with their height or weight as required in A4 size paper hand written.)
b) Use of formula and calculation of
mean, median and mode of the data specified for the group.
c) Cumulative frequency curves drawn by
the group.
d) Use of internet for downloading
standard data and preparing height weight chart.
e) Comparing the observed data with the standard
data and identifying the underweight, overweight and normal weight students of
the target group.
f) Preparing the project report in A4
size paper sheets and making a booklet
g) Presentation of findings
7) Overview:
a) The application the of formulas to
calculate the mean, median and mode of the specified data and interpretation
with understanding what these numbers actually mean
b) Techniques/Methods used to compare of
findings with the BMI chart and arriving at certain conclusion
c) Presentation and relevance of project
Report
2PLAN PHASE
The entire class comprising 57 students was divided into 12 small groups.
Tasks are assigned to each group based on specific data. The data specified for
each group is different and the task assigned for each group are the same. The
expected date for completion of the project was fixed on 30^{th}
November 2016.

3DO PHASE
The assigned
tasks were performed by each group with respect to the specific data allotted
to each group. A project report is prepared and submitted. The project report
included the following items.
1) Raw data sheet
2) Specific data sheet
3) Task sheet
4) Graph with Ogives
5) BMI chart or HeightWeight Chart
6) Calculation of mean, median and mode
using formula and related table of values
7) Outcomes or Findings of their group
work
8) Brief report of work done by the
group
9) Suggestions if any by the group
10) Photos /ppts/paper cuttings/audio or
visual aids to support the work.(not compulsory)
4REVIEW PHASE
The progress
of work done by the students was monitored and necessary help was provided to
complete the project. In some cases difficulty in identification of students, absentees,
difficulty in gathering data, calculating mean, median, mode, doubts in
plotting graphs were reported. Suitable help were provided to overcome these
difficulties. The reflection of the outcomes was also discussed.
5MANAGE PHASE
The overall
project work was closely monitored and the progress was assessed from time to
time. The doubts of students were cleared. The weak students were encouraged to
participate with students in completing the tasks. For this purpose a task
sheet was prepared indicating the work allotted to each member of the group.
The group members collectively consolidated their work and report was prepared
and presented group wise.
6. OUTCOME OF THE PROJECT:
The students
actively took part in the project and completed the tasks assigned to them. The
summary of the findings of each group are tabulated and presented below. It was
successfully completed though initially the children were not enthusiastic.
When the findings of one group was discussed in the class they found something
new in the study,all other groups were actively participated to complete the
tasks before FA3.However two groups could not complete the task in time. They
were given extra time and students from other groups helped them to complete
the project. It was a grant success.

7. INFERENCES
1. It is
found that a large number of students in Upper primary classes are under
nourished. It is closely related to their food habits.
2. The
number of overweight students is less in number in class VI and Class VII. It
is manageable level.
3. The
numbers of underweight students are more in class VIII.
8. SCOPE FOR FURTHER IMPLEMENTATION.
NOT THE END,
A NEW BEGINNING
