Science Discourse Instrument

The Science Discourse Instrument (SDI) is an observation tool and rubric used to evaluate the quality of discussions in science classrooms. There are six categories for observation in the SDI, which are considered essential to strong discourse in science classrooms, three of the categories focus on teachers and three focus on students. The categories for teachers are: asking open ended questions; pressing for explanation; and linking discussions. The categories for students are: explanation of ideas; co-constructing ideas with peers; and critiquing the reasoning of others.

Psychometric Considerations

Psychometrics is the science of psychological assessment. A primary goal of EdInstruments is to provide information on crucial psychometric topics including Validity and Reliability – essential concepts of evaluation, which indicate how well an instrument measures a construct - as well as additional properties that are worthy of consideration when selecting an instrument of measurement.
