This article presents a historical review of mathematics education since the late 1950s in the United States. Three themes are used to organize the literature reviewed in the article: (a) broad sociopolitical forces, particularly highly publicized educational policy statements; (b) trends in mathematics research; and (c) theories of learning and instruction. At times, these themes coincide, as ...

A neurodevelopmental screen in the medical examination of 3750 school entrants with a mean age of 5 years 4 months was validated as a predictor of coordination and communication difficulties. Class teachers of 6, 7, and 8 year olds completed a questionnaire about motor and communication success and difficulty in school activities. Below average ratings on the neurodevelopmental screen were asso...

This is a small pattern language for running online trainings. The language starts with an entry pattern ONLINE TRAINING. All other patterns are supporting this pattern and help to make online trainings more alive. Some of the patterns are not exclusive for online uses, for instance PREPARED EXAMPLE or TEST RUN. These patterns could be part of a pattern language for trainings as well. They are ...

Purpose In this epilogue, we review the 4 response articles and highlight the implications of a multidimensional view of reading for the assessment and instruction of reading comprehension. Method We reiterate the problems with standardized tests of reading comprehension and discuss the advantages and disadvantages of recently developed authentic tests of reading comprehension. In the "Instru...

Twenty-four fifth grade (or equivalent age) students were assigned to one of two treatment conditions consisting of equal numbers of students from regular and special education classes. One group was involved in a dramatic games condition culminating in a theatrical performance planned by the group. The second group was involved in a noncompetitive games condition culminating in a demonstration...

Why should wait for some days to get or receive the special sciences and the unity of science book that you order? Why should you take it if you can get the faster one? You can find the same book that you order right here. This is it the book that you can receive directly after purchasing. This special sciences and the unity of science is well known book in the world, of course many people will...

A single facility problem in the plane is considered, where an optimal location has to be identified for each of finitely many time-steps with respect to time-dependent weights and demand points. It is shown that the median objective can be reduced to a special case of the static multifacility median problem such that results from the latter can be used to tackle the dynamic location problem. W...

Special libraries all over the world today fulfil a whole variety of different services at a wide range of locations. This diversified spectrum of activities is by no means a recent development. At the time that the Special Library Association (SLA) was founded at the 1909 conference of the American Library Association (ALA), special libraries already had little to do with traditional library t...

  We consider the two well knownminimax and minisum single facility location problems in the plane which has been divided into two regions, and by a straight line. The two regions are measured by various norms . We focus on three special cases in which the regions and are measured by and norms, and block norms, two distinct block norms. Based on the properties of block norms then we use linear ...

in this paper, we consider a special case of weber location problem which we call goal location problem. the weber location problem asks to find location of a point in the plane such that the sum of weighted distances between this point and n existing points is minimized. in the goal location problem each existing point pi has a relevant radius ri and it’s ideal for us to locate a new facility o...
