Abstract
This article describes two related studies that began to explore the validity of scores from select-and-fill-in (SAFI) concept map assessments as measures of students’ connected understanding of science. Scores from SAFI maps created for this purpose and used with middle school students and undergraduate astronomy students possessed high internal consistency and exhibited large mean increases with increased domain exposure. SAFI scores were strongly related to scores from a standardized multiple-choice (MC) achievement measure for middle school students; work with individual students suggested that they used strategies requiring connected understanding to successfully complete the maps. SAFI scores from undergraduate students exhibited large relationships with scores from direct-instruction MC exams and scores from a relatedness ratings measure, taken together and separately. Results provide initial evidence of the validity of scores from SAFI maps as measures of connected understanding of science in middle school and undergraduate introductory science students.
