Maimonides' Rule
Maimonides' rule is named after the 12th-century rabbinic scholar Maimonides, who identified a correlation between class size and students' achievements. Today this rule is widely used in educational research to evaluate the effect of class size on students' test scores. Maimonides' rule states that a class size may rise to an upper limit of 40 students. Once this quota is reached the class is cut in half, so instead of one class with forty-one students there are now two classes: one with twenty students and one with twenty-one students. Joshua Angrist and Victor Lavy (1999) have used "the nonlinear relationship between the local number of students and the class size predicted by Maimonides' rule to estimate the impact of class size on student performance, and evaluate the effect of being just below the number of students for whom an additional teacher would be brought up, and of being just above this number." Their results have shown highly irregular patterns in class size that ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maimonides

He died in Egypt on 12 December 1204, when his body was taken to the lower Galilee and buried in Tiberias. During his lifetime, most Jews greeted Maimonides' writings on Jewish law and ethics with acclaim and gratitude, even as far away as Iraq and Yemen. Yet, while Maimonides rose to become the revered head of the Jewish community in Egypt, his writings also had vociferous critics, particularly in Spain. Nonetheless, he was posthumously ackno ...

Standard Deviation
In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the values are spread out over a wider range. Standard deviation may be abbreviated SD, and is most commonly represented in mathematical texts and equations by the lower case Greek letter σ (sigma), for the population standard deviation, or the Latin letter '' s'', for the sample standard deviation. The standard deviation of a random variable, sample, statistical population, data set, or probability distribution is the square root of its variance. It is algebraically simpler, though in practice less robust, than the average absolute deviation. A useful property of the standard deviation is that, unlike the variance, it is expressed in the same unit as the data. The standard deviation of a popu ...

Educational Psychology
Educational psychology is the branch of psychology concerned with the scientific study of human learning. The study of learning processes, from both cognitive and behavioral perspectives, allows researchers to understand individual differences in intelligence, cognitive development, affect, motivation, self-regulation, and self-concept, as well as their role in learning. The field of educational psychology relies heavily on quantitative methods, including testing and measurement, to enhance educational activities related to instructional design, classroom management, and assessment, which serve to facilitate learning processes in various educational settings across the lifespan.Snowman, Jack (1997). Educational Psychology: What Do We Teach, What Should We Teach?. "Educational Psychology", 9, 151-169 Educational psychology can in part be understood through its relationship with other disciplines. It is informed primarily by psychology, bearing a relationship to that discipline a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
