Calculating Percentage Agreement Correctly but Writing Its Formula Incorrectly

Differences in visual attention between those who correctly and incorrectly answer physics problems

This study investigated how visual attention differed between those who correctly versus incorrectly answered introductory physics problems. We recorded eye movements of 24 individuals on six different conceptual physics problems where the necessary information to solve the problem was contained in a diagram. The problems also contained areas consistent with a novicelike response and areas of h...

Reading Student Essays May Be Hazardous to Your Spelling: Effects of Reading Incorrectly and Correctly Spelled Words

In two experiments, we examined effects on spelling of reading and of reproducing correctly and incorrectly spelled words. Reading correctly and incorrectly spelled words influenced later spelling accuracy for those same words. Reproducing the spelling of words did not have any effects on later spelling accuracy beyond those produced by reading the words. However, reproducing a correctly spelle...

Diabetic mouse incorrectly typed.

In our report "Three recessive loci required for insulin-dependent diabetes in nonobese diabetic mice" (1), we outcrossed diabetes-susceptible strain NOD mice with diabetes-resistant strain NON, backcrossed the resistant F1 hybrids to the susceptible NOD parental strain, and analyzed segregation of diabetogenic genes. We reported that 1 of 19 mice developing diabetes at first backcross apparent...

An Exact Formula for Calculating Inverse Radial Lens Distortions

This article presents a new approach to calculating the inverse of radial distortions. The method presented here provides a model of reverse radial distortion, currently modeled by a polynomial expression, that proposes another polynomial expression where the new coefficients are a function of the original ones. After describing the state of the art, the proposed method is developed. It is base...
