摘要:When deploying online homework in physics courses, an important consideration is how many tries learners should be allowed to solve numerical free-response problems. While on the one hand, this number should be large enough to allow learners mastery of concepts and avoid copying,...

摘要:Asynchronous online student discussions of online homework problems in introductory physics courses are analyzed with respect to course type, student course performance, student gender, problem difficulty, and problem type. It is found that these variables can significantly chang...

摘要:We discuss the development and functionality of the LON-CAPA system with a particularfocus on its homework and examination functionality. We also describe its more generalapproach to course management and its infrastructure for course content sharing and reuse.We then focus on me...

摘要:We describe a history of physics course, cotaught by a physicist and a historian of physics, on the quantum and relativity revolutions in the early part of the 20th century. The course has been taught both in Europe as part of a study abroad program and as a regular on-campu...

摘要:Item Response Theory (IRT) has proven useful in physics education research to examine the validity of concept tests (e.g., Refs. 1-3) and online homework (e.g. Refs. 4-6), yet as a tool for the improvement of physics instruction (particularly exams), it is oftentimes perceived as...

摘要:The understanding of many aspects of astronomy is closely linked with relativity and the finite speed of light, yet relativity is generally not discussed in great detail during planetarium shows for the general public. One reason may be the difficulty to visualize these phen...

摘要:I think most physics teachers would agree that two important components of a proper solution to a numerical physics problem are to first figure out a final symbolic solution and to only plug in numbers in the end. However, in spite of our best efforts, this is not what the m...

摘要:“What would you see if you were riding a beam of light?” This thought experiment, which Einstein reports to have “conducted” at the age of 16,1 of course has no sensible answer: as Einstein published a decade later, you could never reach the speed of light....
