The Attitude toward Science School Assessment (ATSSA) is used to measure evaluate the relationship between attitude toward science and achievement in science. The instrument went through validation studies that resulted in reduction in the number of items in the instrument.
The link provided is to a study that both describes the development and validation of the ATSSA as well as the ATSSA itself.
The Modified Attitudes towards Science Inventory (mATSI) measures students' attitudes towards science related to such factors as students' perceptions of the science teacher, anxiety toward science, value of science in society, self-concept toward science and desire to do science. This 25-item inventory uses a 5-point Likert scale.
The linked website contains the mATSI as well as information and reviews about it.
The Motivated Strategies for Learning Questionnaire (MSLQ) was developed to measure the types of learning strategies and academic motivation used by college students. This is a 44-item instrument that uses a 7-point Likert scale.
The MSLQ is both linked and attached, and its documentation is linked.
The Perceived Competence Scale (PCS) is a short, 4-item questionnaire, and it assesses participants' feelings of competence about, say, taking a particular college course, engaging in a healthier behavior, participating in a physical activity regularly, or following through on some commitment. Because the PCS pertains to particular behaviors or behavioral domains, it can be easily adapted to study additional behaviors or behavioral domains.
The Science Motivation Questionnaire II (SMQ-II) contains 25 items regarding students' motivation to learn science in college courses. Students respond on a 5-point rating scale of temporal frequency ranging from (0) never to (4) always. The SMQ-II contains five montivation components: intrinsic motivation, self-determination, self-efficacy, career motivation, and grade motivation. Each component is measured with 5 separate items.
