New technologies in the globalized world are well developed and modern, but 
peoples morals have probably declined. Children are not raised properly these 
days and are not trained to become responsible adults in the future. People 
who are not aware of what is good and right will absorb bad things, such as; 
drugs, pornography, and gambling. Training in the four foundations of mindfulness 
can serve in the place of inadequate study materials and will help teachers 
to assist children in learning.	The purposes of this research were to develop 
the video lesson on " Meditation by the Four Foundations of Mindfulness" for 
prathom 6 student  and to study the students' Practice Skill outcome using 
the video lesson. The population were  71 sixth grade students of
Watchaichompon-chanasongkram school, Amphoe Muang , Changwat 
Kanchanaburi studying during the second semester  of the 2001 academic year. 
The experiment duration were 24  periods, 20 minutes each. The instrument 
consisted of : 

1) The video lesson on "Meditation by the Four Foundations of Mindfulness" 
for prathom 6 students, 

2) The practice skill test, 

3) Meditation Behavior  test, 

4) An opinion test after  using the video lesson. The data were then  analyzed 
for arithmetic  mean (), median (Mdn), inter quartile rank (IR) ,standard deviation 
(S.D.) and paired t- test value by  SPSS for windows.

The results of  the study were as the following :

1.   The video lesson efficiency had 85.75 coefficient index value meaning a very 
high level of efficacy. 

2.   The student' practice skill outcome after using the video (= 16.01, S.D.= 0.84) 
was higher than the one before using the video (= 7.76, S.D.= 2.32), resulting in 
the mean difference of 8.25 or 41.25 percent of the full scores.

3. The opinions of students taught by using the video lesson  were found a high 
level  of  agreement. ( = 4.14, S.D.= 0.85)
