چکیده
Generative educational assessments such as essays or drawings allow students to express their ideas. They provide more insight into student knowledge than most multiplechoice items. Formative guidance on generative items can help students engage deeply with material by encouraging students to e↵ectively revise their work. Generative items promote scientific inquiry by eliciting a variety of responses and allowing for multiple correct answers, but they can be di cult to automatically evaluate. We explore how to design and deliver automated formative guidance on generative items requiring precollege students to draw the arrangement of atoms before and after a chemical reaction. The automated guidance is based on a rubric that captures increasing complexity in student ideas. Findings suggest that the automated guidance is as e↵ective at promoting learning as teacher-generated guidance, measured both by immediate improvement on the revised item and preto post-test improvement on a near-transfer item. Immediate and delayed delivery of automated guidance are equally e↵ective for promoting learning. These studies demonstrate that embedding automated guidance for chemistry drawings in online curricula can help students refine their understanding. Providing automated guidance can also reduce the time teachers spend evaluating student work, creating more time for facilitating inquiry or attending to the needs of individual students.

Towards Formative Feedback on Student Arguments
This paper presents our ideas on generating formative feedback in the Genetics Argumentation Inquiry Learning (GAIL) system. GAIL will provide undergraduate biology students with tools for constructing Toulmin-style arguments on questions in genetics. Feedback will be based in part on the output of GAIL’s argument analyzer, which will compare learner arguments to automatically constructed exper...
متن کاملIndividual differences in the effect of feedback on children's change in analogical reasoning
Various forms of feedback are used in formative assessment and interactive learning environments. The effects of different types of feedback are often examined at a group level. However, effective feedback may differ in learners with different characteristics or between learners at different stages in the learning process. In this paper explanatory item response theory (IRT) models are used to ...

Civic innovators design real-world solutions to societal problems. Teaching civic innovation presents serious challenges in classroom orchestration because facilitators must manage a complex learning environment (which may include community partners, open-ended problems and long time scales) and cannot rely on traditional classroom orchestration techniques (such as fixed schedules, pre-selected...
متن کاملRobust Student Knowledge: Adapting to Individual Student Needs as they Explore the Concepts and Practice the Procedures of Fractions
Robust knowledge consists of both conceptual and procedural knowledge. In order to address both types of knowledge, offering students opportunities to explore target concepts in an exploratory learning environment (ELE) is insufficient. Instead, we need to combine exploratory learning environments, to support students acquisition of conceptual knowledge, with more structured learning environmen...
