This case study used a design-based research approach to examine the development and evaluation of an online homework system to support learning and problem-solving in a high school physics course. Emergent themes included challenges of building the system, strengths and weaknesses of it, and the benefits to students. While the system largely met…

The QuVis Quantum Mechanics Visualization Project provides freely available research-based interactive simulations with accompanying activities for the teaching and learning of quantum mechanics across a wide range of topics and levels. This article gives an overview of some of the simulations and describes their use in an introductory physical…

The goal of this study was to investigate the timing of online homework completion and its effects on student performance. Data was collected from two large, first-semester general chemistry sections at a southwestern university. Specifically, this study aims to explore the link between when students complete their homework relative to the date…

Feedback-driven online homework systems provide students with a comprehensive set of practice questions that can accompany and enhance other instructional resources. However, the available e-homework systems do not contain content that aligns well with our course objectives, provide too few questions in key areas, and use assessment format(s) that…

This article describes a grading approach that encourages students to employ particular problem-solving skills. Some strengths of this method, called "process-based grading," are that it is easy to implement, requires minimal time to grade, and can be used in conjunction with either an online homework delivery system or paper-based homework.

Two different online homework systems were administered to students in a first-quarter general chemistry course. This study used a multiple regression model to control for the students' academic and socioeconomic background, and it was found that students who completed the online homework activities performed significantly better on a common…

This paper outlines the use of "how to" videos, in the form of a screencast using a tablet computer, and posting the videos online. These videos are useful for when students miss a class, for those students who need to review a lesson or examples used in class when doing homework or reviewing for a test, for instructors of online classes, and also…

Three emerging technologies were used in a large introductory chemistry class: a tablet PC, a lecture capture and replay software program, and an online homework program. At the end of the semester, student usage of the lecture replay and online homework systems was compared to course performance as measured by course grade and by a standardized…

Personalized, online homework was used to supplement textbook homework, quizzes, and exams for one section of a course in material and energy balances. The objective of this study was to test the hypothesis that students using personalized, online homework earned better grades in the course. The online homework system asks the same questions of…

Online homework assignments have been shown to enhance student performance. Our research on gendered responses to these assignments adds new and useful information. We investigated differences between male and female students' responses to online homework in large-enrollment general chemistry courses. Replacing in class quizzes with online…

Physics teachers are most effective when their students are active learners who think and participate in every class. This extends beyond the classroom too: ideally, students would tackle challenging questions and exercises after every class--not just before the exam or the night before the weekly homework is due. Just-in-Time-Teaching was…

We investigate short-term learning from hints and feedback in a Web-based physics tutoring system. Both the skill of students and the difficulty and discrimination of items were determined by applying item response theory (IRT) to the first answers of students who are working on for-credit homework items in an introductory Newtonian physics…

Instructors can use interactive Java applets to present science in a concrete and meaningful manner to nonscience majors. This article shows how applets can take the place of laboratory work and gives examples and benefits of using applets. (Contains 1 table and 3 figures.)

We studied students performing a complex learning task, that of solving multipart physics problems with interactive tutoring on the web. We extracted the rate of completion and fraction completed as a function of time on task by retrospectively analyzing the log of student-tutor interactions. There was a spontaneous division of students into three…

Describes a hybrid instructional format designed to improve large lecture courses that couples online homework with in-class, active learning exercises. Indicates that most students felt that student-instructor interaction was better than in traditional courses and that online homework aided time management and learning. Suggests that online…
