The
Development and Validation of a Classroom Environment Scale for
Filipinos
Field Testing of the LES From November 11, 1996 through January 14, 1997, the LES was field tested on a total random sample of 720 high school chemistry students (10 students per class and approximately equal number of boys and girls) from randomly selected 72 classes (6 classes per school) in 12 randomly chosen big schools in Quezon City. Instead of tediously writing the Filipino translations of some English words in the LES not easily understood by high school students on the board as was done during the prepilot and pilot-testing phases of research, the respondents were provided with a mimeographed copy of a list of these words with their corresponding Filipino translations (Appendix D).
The respondents were pulled out from their chemistry class in order not
to disrupt the entire class. They were pulled out one class at a time.
However, in some schools, the respondents from the six classes were
excused by the science head teacher so they could all take the tests at
the same time during the day and the researcher did not have to go back
many times to the same school. The tests were given in a vacant
classroom, library or conference room in the absence of the teacher/s to
put the respondents at ease. And as was done during the prepilot and
pilot stages, the answered forms were placed in a brown envelope, which
was labeled with the name of the teacher, subject and section, and date.
It took some 25 minutes for the respondents to complete the LES.
The results were promptly encoded and analyzed statistically using the
SPSS/PC + software. Of the 720 sets of students' responses, nine (9)
were invalidated, reducing the total number of cases to 711.
