The objectives of this study were to construct and
develop a two-tiered multiple-choice test for the measurement
of student misconceptions in optics at the level of
secondary education in Thailand, as well as to investigate
the effects of gender, grade level, and type of school upon
levels of student misconceptions.
Misconceptions were measured by the Two-Tiered Optics
Misconception (TTOM) test instrument developed for this
study. Based upon criteria-evidence, the validity or appropriateness,
meaningfulness, and usefulness of inferences
derived from scores obtained from administration of the
instrument was demonstrated at acceptable levels. The TTOM
was administered to 932 high school subjects from randomly
selected all-male, all-female, and coeducational 10th
through 12th grade classes in Bangkok, Thailand.
A mixed analysis of variance model was used to investigate the effects of gender, grade level, and type of
school upon subject misconception scores in the field of
optics. Analysis of the data revealed the following: 1) a
paper-pencil test based upon a pattern of two-tiered
multiple-choice questions and reasons developed for this
study provided a valid and reliable measure of student misconceptions in optics at the level of secondary education in Thailand; 2) gender, grade level, and type of school did
not have significant effects upon subject misconception
scores among Thai high school students; 3) the subgroup
school within type was found to have a significant effect
upon subject misconception scores; 4) when fixed grade levels were considered for type of school, there were significant differences in misconceptions among 12th grade subjects from different types of schools; 5) certain consistent misconceptions in the area of optics, related to the
properties of a converging lens, images from a plane mirror
and a converging lens, light rays, regions of light travel,
shadow formation, and lightning flashes, existed among Thai
physics students at the level of secondary education. / Graduation date: 1994
