Statistical estimation of influence of visual
methods of activating studying in a lesson by level of students knowledge’s
In the
time when information arises and become outdated so
fast the role of teachers was changed. He is stop to be a «source of knowledge»
and «store of experience» of past generations, but start to be a “vector” in
the great «numerical ocean» of information. It is impossible to imagine teacher
who knows everything, but possible to imagine a person who lead students in
they search, who can share experiences
with students and teach them how and where to find a information and how to use
it for studying and also for professional needs.
In every high pedagogical school, a future teacher learns a methods of
activating students attention, but not so many teachers include it in their
teaching process, Forgot about them or not considered effective.
About 2000
years ago for studying and getting new
information about objects around, we used all possibilities such as: visual
observation, hearing abilities, tasting, smelling, touching. But now, when
World web sources are free, cheap and acceptable for everyone in any place of
the Earth, people are accepting 80% of information through the eyes(reading and
watching) and ears. In such monotonous process of guttering information, is
very easy to lose a purpose and interest to study.
The purpose of this research is finding a dependence between using methods
of «activation» and level of students
knowledge. Among many methods we can select a method of visualization.
The experiment was prepared and carried out in a class of 1st year
students of Luhansk medical university (Luhansk, Ukraine), course «Medical
and biological physics».
Into Data 1 we are arrange a 19 students(2 academic groups) who learn
materials as usually(Table 1) and into Data 2 - 20 students who watch a studying movies
(animation movies) during the lesson(Table 2).
The
movies been created in the animation program, sounded in English, include a text explanation (in English too) during a sound
track and showing 3 topics: Process of osmosis through biomembrane,
Receptors linked to a channel protein, Work of sodium-potassium exchange
pump. Summary time for presentations is 23 minutes which had been combined with
usual scheme of explanation by this topic.
Data’s for analysis are include
a students number(by order) and result of students testing by topic( 0-20
point);
Hypothesis 
- have no difference in the level of knowledge’s between
students from the Data 1 and Data 2, hypothesis 
- some difference is
present.
Necessary
to estimate numerical(serial) data’s, so better to use a nonparametric
criterion of Wilkokson (Wilkokson–Mann–Whitney`s). Results been combine into 1
set, ranked, found 2 values of parameters 
and 
and used them for finding a parameter 
. It is bigger then critical 
(from standard table
of critical values for Wilkokson criterion), so
hypothesis 
has been rejected by significance level 
.
A difference between level of knowledge’s in the 1st and 2nd
data’s was proved for choused size of data’s, so influence from the visual method of
activation a students studying activity is present. The analysis for bigger data(by the expanded criterion of Wilkokson) in the process of estimation.
As result of our estimation we proof a proverb: «All new it is a forgotten old». Not important how useful and popular a electronic sources
of information, but a teacher who enjoy his work, who try to make a cognitive process easy and interesting for
students will be claimed at all time.
