This paper illustrates how the combination of teacher and computer guidance can strengthen collaborative revision and identifies opportunities for teacher guidance in a computer-supported collaborative learning environment. We took advantage of natural language processing tools embedded in an online, collaborative environment to automatically score student responses using human-designed knowledge integration rubrics. We used the automated explanation scores to assign adaptive guidance to the stu...

AbstractGraphs illustrating complex scientific relationships require students to integrate multiple concepts and visual features into a coherent understanding. We investigate ways to support students in integrating their understanding of density concepts through a graph that is linked to a simulation depicting the relationship between mass, volume, and density. We randomly assigned 325 8th-grade students to 1 of 2 graphing activities. In the analyze condition, students plotted a set of data poin...

Science is increasingly characterized by participation in knowledge communities. To meaningfully engage in science inquiry, students must be able to evaluate diverse sources of information, articulate informed ideas, and share ideas with peers. This study explores how technology can support idea exchanges in ways that value individuals’ prior ideas, and allow students to use these ideas to benefit their own and their peers’ learning. We used the Idea Manager, a curriculum-integrated tool that en...

ABSTRACTThis study is inspired by laboratory studies demonstrating that distributing study sessions over time better supports learning and retention than clustering sessions. We compare two implementations of a multi-day inquiry science unit: in the clustered instruction condition, students completed an inquiry unit in five consecutive class periods. In the distributed instruction condition, students completed one activity per week for five weeks. Both conditions resulted in significant and simi...

In this chapter, we report upon the iterative development of an online instructional unit featuring virtual laboratory activities that target the physical science concepts of density and buoyancy. We introduce a virtual laboratory activity that was designed to facilitate exploration of the relationship of mass and volume to buoyancy. We evaluate the virtual laboratory by measuring the extent to which it fosters meaningful experimentation, appropriate interpretation of evidence, and discovery of ...

Supporting students to revise their written explanations in science can help students to integrate disparate ideas and develop a coherent, generative account of complex scientific topics. Using natural language processing to analyze student written work, we compare forms of automated guidance designed to motivate productive revision and help students integrate their understanding of science. Research shows the benefit of providing timely, transparent guidance to students and identifies some chal...
