Abstract:
This research was undertaken to study a learning achievement ofclassroom
instruction using concept and principle teaching model. The theme used for the instruction
was "the AC circuit analysis". It was hypothesized that the teaching model developed would
have over all efficiency not less than 80/80 and the achievement would vary on the students
individual ability.
By their characteristics, 9 concepts and 4 principles were representatively extracted
from the content and were transformed in to teaching - learning activities. Examples and nonexamples
including various concepts attributes were gathered to develop plan for instruction.
All necessary items involving pre, post and formative tests were constructed to measure all
vital learning outcomes. All items developed were evaluated and expert-approved for their
reliability. validity and feasibility.
The teaching models was implemented with 35 second year students in the
department of Electrical Technology of Sattahip Technical College. Prior to the model
implementation, fundamental knowledge was remedied. Pre and post as well as formative test
were performed during the experiment. A summative evaluation was also made after the lesson
completion
It was found that all students benefited from concept and principle teaching models.
A significant statistical differences at .05 level were found from pre and post test. Higher
ability students exhibited much higher scores than the intermediate and the low ability. There
was no significant difference found between the moderate and the low ability students.
The study, however, revealed an interesting fact that the concept teaching model
had higher efficiency than the principle model. The concept instruction supported the
hypothesis giving 94/81.24 efficiency while the principle exhibited only 80/58.80 This
incidence might partially be due to the difficulty of some post test items. It was later found
from an investigation that situations used in the post test were much higher level and much
difference from the classroom application.
