Abstract: Identifying material with which students are struggling can guide educators’ decisions on which modifications to the instructional experience will be most impactful to the learning experience. Educators make a finite selection of the nearly infinite number of possible combinations of instructional content, delivery approaches, instructional order, test questions, approaches for accountability, rubrics, and the like. Educators and administrators with thousands of students are incapable of processing the quantities of available data unaided. In some embodiments, a system enables users to view quantized metric data from a population of, for example, students. In some embodiments, the system displays a category-filtered presentation table of a single metric data source.

Abstract: An assessment system may present one or more string interaction problems to each of a plurality of students. Students may provide answers to string interaction problems in the form of string edits that, for example, identify deletions, additions, or revisions to a text string of each respective string interaction problem. The assessment system may normalize each string edit by converting each string edit into a student range edit. Each student range edit defines a replacement text string (which could be an empty text string) to be inserted within a range of reference locations relative to an original text string of the string interaction problem (which likewise could be an empty text string). An assessor may associate feedback objects with student range edits that match or, in some embodiments, are within a predetermined distance of an assessor-defined range edit.

Abstract: A student instruction system may include a graphic user interface to facilitate student instruction, marker placement to form answers, and automatic grading. In various embodiments, an instructional unit subsystem may display instructional units, challenge problems, and/or markers that can be user-manipulated to form answers to the challenge problems. Teachers or other graders can create grade rules defined for selective application to the student-placed markers. The system and methods facilitate the display and placement of markers on video annotation instructional units and text annotation instructional units.

Abstract: Systems and methods are described herein to display and manage royalty distributions for electronic book (eBooks) assembled from multiple instructional units owned by a plurality of owners. In various embodiments, a curation fraction value (CFV) subsystem may calculate a CFV for an assembly owner of the assembled eBook. An owner value profile (OVP) subsystem may generate an OVP data object for the assembled eBook that associates each identified unit owner with a value sum, based on computed value units of the instructional units owned by each respective unit owner. A royalty distribution subsystem may compute a distribution of royalties to the assembly owner and the various unit owners. A share of the royalty for a unit owner may be recursively sub-divided for distribution to nested assembly owners and nested unit owners when one of the instructional units is itself an eBook formed from multiple nested instructional units.

Abstract: The present disclosure provides systems and methods relating to creating, administering, and evaluating assessments, such as quizzes and tests. According to various embodiments, assessors create challenge problems that can be answered by assessees through the creation and/or manipulation of geometric shapes. Assessors can evaluate and assign feedback objects to geometric shape answers created by the assessees. The geometric shape answer items can be graded via a grading subsystem in batches and/or through a rule-based system to increase the efficiency and consistency of the grading process.

Abstract: The present disclosure provides systems and methods relating to administration, evaluation, and review of assessments, such as quizzes and tests. According to various embodiments, a first challenge problem of an assessment may be displayed to an assessor, such as an instructor of students. The first challenge problem may include one or more answers provided by an assessee, such as a student. For example, an assessee may have answered the challenge problem by providing one or more digital ink stroke answers, a draggable object answer, and/or an annotation answer. The systems and methods described herein facilitate the automatic and/or semi-automatic evaluation of the assessee answer items.
