Türker, Fatma
The purpose of this study is to develop a three-tier test for assessing high school students̕ misconceptions concerning force and motion. The first tier is a traditional multiple choice item, the second tier presents several alternatives addressing the reason for the response for the first tier, and the third tier asks if examinees are confident for their responses to the first two tiers. In the process of test development, Force and Motion Test Requesting Reasoning was developed and utilized to determine the alternatives of Force and Motion Three Tier Test (FMTTT). The test was administered to 207 students, but 19 students were removed from all analyses due to too many missing items. For checking validity of the FMTTT, correlation was investigated between confidence levels and student scores on the first two tiers, and also correlation between confidence levels and student misconception scores on the first two tiers was investigated. Factor analyses were conducted using scores and misconception scores; and percentages of false negatives and false positives were estimated. The percentages of false negatives and false positives were found to be 6% and 8%, respectively. The reliability coefficients were estimated for student scores and misconception scores as 0.48 and 0.62, respectively. In conclusion, using the FMTTT as an achievement test may not be as reliable as using it as a misconception test.

The main purpose of this study was to develop a three-tier test for assessing ninth-grade students̕ misconceptions about simple electric circuits. The first tier of an item on the test presents an ordinary multiple choice question, the second tier presents a set of reasons for the response given to the first tier, and the third tier questions if examinees are confident for their responses to the first two tiers. The study was carried in Polatlı, the biggest outlying district of capital Ankara. In the light ...

Kutluay, Yasin; Eryılmaz, Ali; Department of Secondary Science and Mathematics Education (2005)
The main purpose of this study was developing a three-tier test for assessing 11th grade students̕ misconceptions about geometric optic. The accessible population was all 11th grade science students in Bayrampasa, Istanbul. While developing the test, interviews and open-ended tests were used to collect data to create the three-tier test. An interview questionnaire was developed based on the literature review. 15 11th grade students were interviewed by this questionnaire. Then, an open-ended test was created...

Using Three-Tier Diagnostic Test to Assess Students' Misconceptions of States of Matter
KIRBULUT, ZÜBEYDE DEMET; Geban, Ömer (2014-10-01)
This study involves the development of a three-tier diagnostic test to measure high school students' understanding of states of matter concepts. The States of Matter Diagnostic Test (SMDT) is a 19-item three-tier diagnostic test consisting of three-tier items for assessing students' understanding of states of matter concepts. The SMDT was administered to 195 10th grade high school students in the pilot study and 102 10th grade high school students in the main study. Cronbach alpha reliability indexes for th...
