This study investigated the learning and assessment efficacy of a physics video game we developed called Newton's Playground. 165 8th and 9th graders played Newton's Playground for roughly five hours. Findings include significant pre-post physics gains and notable correlations between performance in Newton's Playground and physics pretest knowledge.(More)
Keywords: Interdisciplinary projects Lifelong learning Media in education Multimedia/hypermedia systems a b s t r a c t The relationship between video gameplay, video game genre preference, personality, and GPA was investigated in an online correlational study with university students. In addition to administering self-report measures of GPA and(More)
PURPOSE To evaluate and compare the glaucoma discrimination ability of macular inner retinal layer (MIRL) thickness with that of peripapillary retinal nerve fiber layer (pRNFL) thickness measured by spectral-domain optical coherence tomography (RTVue-100; Optovue Inc, Fremont, CA) in patients with normal-tension glaucoma (NTG). METHODS Sixty-five healthy(More)
PURPOSE We evaluated the clinical use of segmented macular layer thickness measurement in terms of glaucoma diagnosis and the ability to detect progression, and to compare such outcomes to those by circumpapillary retinal nerve fiber layer (cRNFLT) and total macular thickness (TMT) measurements. METHODS The study included 141 glaucomatous and 61 healthy(More)
Educators today are increasingly interested in using game-based assessment to assess and support students' learning. In the present study, we investigated how changing a game design element, linearity in gameplay sequences, influenced the effectiveness of game-based assessment in terms of validity, reliability, fairness, learning, and enjoyment. Two(More)
The aim of this study was to evaluate the incidence of and risk factors for the development of diabetic retinopathy (DR) and progression to proliferative DR (PDR) in Korean patients. Patients diagnosed with type 2 diabetes and followed for more than 5 years at a university-based clinic since 2000 were consecutively enrolled in this retrospective cohort(More)
PURPOSE To investigate correlations between preoperative and postoperative foveal microstructures in patients with macula-off rhegmatogenous retinal detachment (RRD). METHODS We reviewed the records of 31 eyes from 31 patients with macula-off RRD who had undergone successful re-attachment surgery. We analyzed data obtained from complete ophthalmologic(More)
PURPOSE To evaluate the characteristics of spectral-domain optical coherence tomography (SD-OCT) findings associated with visual outcome and compare OCT measurements according to presence of cystoid macular edema (CME) in retinitis pigmentosa (RP) patients. METHODS Patients with typical RP who underwent SD-OCT were included. We compared OCT measurements(More)
In Education (as in many other fields) it is common to create complex systems to assess the state of latent properties of individuals — the knowledge, skills, and abilities of the students. Such systems usually consist of several processes including (1) a context determination process which identifies (or creates) tasks—contexts in which evidence can be(More)
PURPOSE To evaluate the glaucoma progression in patients with a history of refractive corneal surgery (RCS). METHODS A total of 313 eyes of 313 glaucoma patients (RCS group, 34 eyes; non-RCS group, 279 eyes) with a mean follow-up period of 2.7 years were included. Glaucoma progression was determined either by experts' stereoscopic optic disc/retinal nerve(More)
