3.1 Measurement of General Chemistry Self-Efficacy
Many researchers have constructed items and surveys to measure general chemistry
self-efficacy (see Table 1 ). In the paragraphs that follow, I briefly review those
surveys. For example, in the USA, Smist ( 1993 ) used six questionnaire items to
measure a sample of college students
self-efficacy for learning chemistry. The
items were administered to the students before and after they took a freshman
general chemistry course. The internal consistency of data was high (Cronbach
'
s

ʱ ¼
0.90), but the six items were not constructed to measure students
self-efficacy
'
for learning specific chemical concepts.
In New Zealand, Coll, Dalgety, and Salter ( 2002 ) developed fairly broad items to
measure first-year university students
self-efficacy for learning chemistry. Their
revised version of the questionnaire consisted of 17 items with a 7-point semantic
differential format (Dalgety et al., 2003 ; Dalgety & Coll, 2006a , 2006b ). Sample

concepts”]
5-point rating scale from A (quite a
lot) to E (very little)

Please indicate how confident you feel
about [followed by 17 statements, e.g.,
“applying a set of chemistry rules to
different elements of the periodic table,”
“achieving a passing grade in a chemical
hazards course,” “tutoring another stu-
dent in a first-year chemistry course”]
7-point semantic differential for-

confident” and “totally confident”
