There are well-acknowledged challenges to scaling computerized performance-based assessments. One such challenge is reliably and validly identifying ill-defined skills. We describe an approach that leverages a data mining framework to build and validate a detector that evaluates an ill-defined inquiry process skill, designing controlled…

Many national policy documents underscore the importance of 21st century skills, including critical thinking. In parallel, recent American frameworks for K-12 Science education call for the development of critical thinking skills in science, also referred to as science inquiry skills/practices. Assessment of these skills is necessary, as indicated…

We present a method for assessing science inquiry performance, specifically for the inquiry skill of designing and conducting experiments, using educational data mining on students' log data from online microworlds in the Inq-ITS system (Inquiry Intelligent Tutoring System; www.inq-its.org). In our approach, we use a 2-step process: First we use…

The National frameworks for science emphasize inquiry skills (NRC, 1996), however, in typical classroom practice, science learning often focuses on rote learning in part because science process skills are difficult to assess (Fadel, Honey, & Pasnick, 2007) and rote knowledge is prioritized on high-stakes tests. Short answer assessments of…

Administered a laboratory process skills test to 147 year-5 students to assess their investigations, performance, and reasoning in biology, chemistry, and physics. Reports significant correlation between performance and amount of homework done and students' perceptions of several aspects of the classroom environment including personalization,…

The focus on practical investigations in the National Curriculum is seen to be important if students are to attain a connoisseurship in science experimentation. The chain of processes involved in doing real science involves: non-linear thinking; creative flair; and critical evaluation within an authentic setting. The research presented in this…
