One need only look at Trends in International Mathematics and Science Study (TIMSS), Programme for International Student Assessment (PISA), and National Assessment of Educational Progress (NAEP) data to see what a mediocre job is being done of imparting a solid science education to the average American student. There are multiple reasons for this failure, not least the poor preparation of too many teachers whose job it is to teach this critical subject. One key explanation is the poor quality of academic expectations and standards themselves. In science–perhaps even more than other subjects–states must honor their responsibility to set forth, explicitly and rigorously, the skills and content that schools are expected to impart and students are expected… Continue Reading

Eric.ed.gov – Math Space Mission. [A Product of] the Regional Math Network: A Teacher Invigoration and Curriculum Development Project.

eric.ed.gov har udgivet: This unit is intended to teach estimation skills in such a way as to be relevant and useful to students as they apply them in various problem-solving activities. The teaching activities feature the earth, exploration into space, and the other worlds in the solar system. The teacher’s guide contains four modules. Module I suggests the use of several multi-media experiences to set the stage for the activities that follow. Module II, “The Solar System,” incorporates teaching activities dealing with rounding numbers, estimation of sums, differences, products and quotients, graphing, and the application of these skills in problem solving. Module III, “The Space Shuttle,” addresses the use of the space shuttle and stresses the mathematical concepts of ratio and proportion. Module IV,”The Space Colony,” uses geometric concepts as… Continue Reading
