Early elementary schooling in 2nd and 3rd grades (ages 7-9) is an important period for the acquisition and mastery of basic mathematical skills. Yet, we know very little about neurodevelopmental changes that might occur over a year of schooling. Here we examine behavioral and neurodevelopmental changes underlying arithmetic problem solving in a well-matched group of 2nd (n = 45) and 3rd (n = 45...
This paper describes a study in which student-created diagrams about arguments in an ill-defined domain were manually graded by two independent human graders. Findings include that the graders overall agreed with each other on their grades, but their agreement was lower than one would expect in well-defined domains, and higher for solutions of extreme quality.
We develop a protocol for “distributed proctoring” which allows a network of graders to grade individual problems solved by a network of test takers. The mutual anonymity of the test takers and graders is ensured using anonymous MIXs, but an audit trail is provided in the event of a grading dispute. We discuss other applications for this protocol, more generally defined as “digital piecework.”
It is presumed that if you have a limited amount of time for assessing student knowledge, that you should give a test that does not waste time giving students feedback. Feng and Heffernan (2010) compared two such conditions and found the counter intuitive results that the condition that let them get feedback was actually superior (not statistically reliable) than the “test” condition, in which ...
Academic and occupational guidance of the 9th graders require a valid and reliable instrument. Given that Barrett Aptitude Test is widely available, and perhaps used, it was deemed necessary to assess its psychometric characteristics. To this end, a cluster sample of 830 ninth graders from among all such students during the 2017-2018 school year in cities of Saqqez and Bukan, was selected. They...
As Chinese reading engages a different neural network from alphabetic language reading, we investigate whether leftward lateralization of the arcuate fasciculus (AF), as observed in the Western population, is also present in the Chinese population and if it does, whether it is associated with better reading ability. Diffusion tensor tractography analysis on 75 Chinese subjects of three age grou...
BACKGROUND Diabetic retinopathy (DR) is an important biomarker for microvascular disease and blindness. Digital fundus photography is a cost-effective way of screening for DR. Access to DR screening is difficult for many South Africans with diabetes. OBJECTIVE To perform external quality assurance (EQA) on graders registered in the Ophthalmological Society of South Africa DR screening program...
PURPOSE We examined agreement among experts in the assessment of corneal subbasal nerve tortuosity. METHODS Images of corneal subbasal nerves were obtained from investigators at seven sites (Auckland, Boston, Linköping, Manchester, Oslo, Rostock, and Sydney) using laser-scanning in vivo confocal microscopy. A set of 30 images was assembled and ordered by increasing tortuosity by 10 expert gra...
Phonemic Awareness Helps First Graders Invent Spellings and Third Graders Remember Correct Spellings
BACKGROUND To evaluate the accuracy and reliability of fundus retinal photos graded by local graders in Bangladesh with those graded by an expert at the Centre for Eye Research Australia (CERA) in the context of mass scale diabetic retinopathy (DR) screening in Bangladesh. METHODS A population-based cross-sectional study of 3,104 adults identified 213 (7.2%) eligible patients with diabetes of...
