As part of the Ag is STEM: Connecting Agriculture to Environmental and Biological Science Curriculum grant, three separate professional development sessions were facilitated over two years. The professional development sessions aimed to increase the content knowledge, likelihood, and confidence of K-12 science teachers to integrate agricultural concepts into their courses related to the topics of ecology, nutrients, and genes and genetics.   

The data for each year and session topic are compiled in separate data sets, titled either Year 1 or Year 2 and ecology, nutrient, or genes and genetics. Within the data sets the following information can be used to interpret the variables. Interested researchers can also view the label and values columns within the variable view window to see the specific instrument items and measurement information. 

Description of the data and file structure

The data have been uploaded as ‘.csv’ files to increase accessibility. Column naming of study variables is described below:

1) Prefix to indicate the time which the data were collected (Ex: PreQ3_1):

• Pre – Data collected prior to the professional development session (pre-test)
• Post – Data collected 1 week following the professional development session (post-test)
• Mon9 – Data collected 9 months following the professional development session (post-test)
• Mon 17 – Data collected 17 months following the professional development session (post-test)

2) Construct number (Ex: PreQ3_1):

• PartCode – individual participant code for each year and session
• Q3 – How likely participants were to integrate content with an agricultural focus
• Q4 – Participants ranked the factors which influenced their likely to integrate agriculture
• Q5 –Participants could indicate additional factors which influenced their likelihood to integrate agriculture (open-ended question)
• Q7 – How confident participants were to integrate content with an agricultural focus
• Q9 – Participants ranked the factors which influenced their confidence to integrate agriculture
• Q10 – Participants could indicate additional factors which influenced their confidence to integrate agriculture (open-ended question)
• KQ – knowledge questions related to the session’s topic
• KnowCorrect – total number of knowledge questions the participant answered correctly

3) Question number (Ex: PreQ3_1):

• Q3, Q4, Q7, Q9, and KQ have individual items indicated by a different number
• Each individual item can be found in the label column of the variable view window

4) Question responses:

• All question responses have been provided as a number or as text.
• A “.” symbol indicates response not provided.
