It not only gives information to students but also to educators. It contains materials from science, technology, engineering, and mathematics. It is maintained on a regular basis and is easy to navigate threw. http://www.merlot.org/merlot/viewMaterial.htm?id=402597 Crucigrama de Productos Algebraicos. El objetivo de la actividad es desarrollar ejercicios de Algebra en forma grupal. Luego de esto, obtener las claves para completar el crucigrama, y posteriormente, una actividad transversal que consiste en que los alumnos definan en sus propias palabras los conceptos que afloran ahí, y los presenten frente a sus compañeros. http://www.merlot.org/merlot/viewMaterial.htm?id=402603 Crucigrama de Raíces y Racionalización. El objetivo de la actividad es desarrollar ejercicios de Raíces y Racionalización en forma grupal. Luego de esto, obtener las claves para completar el crucigrama, y posteriormente, una actividad transversal que consiste en que los alumnos definan en sus propias palabras los conceptos que afloran ahí, y los presenten frente a sus compañeros. http://www.merlot.org/merlot/viewMaterial.htm?id=380150 This video demonstrates how to use Demos with Positive Impact and describes the benefits of using it in math courses. Demos with Positive Impact is a collection of quick classroom demos that enhance the learning of mathematics content through animations, experiments etc. Each demo comes with stated objective, prerequisites, instructor notes and platform info, plus the level of the demo and credits. This setup appears conducive to quick inclusion into a class. http://www.merlot.org/merlot/viewMaterial.htm?id=651135 This is an interactive Stand Alone Instructional Resource designed to be an additional resource for teaching elementary division. http://www.merlot.org/merlot/viewMaterial.htm?id=449348 Just a technic ,not a proof .One of the students asked me if he could calculate lim sin(x)/x (x---> 0) by Hopital’s law as following. lim sin(x)/x (x---> 0) = lim (sin(x))’/(x)’ (x---> 0) = lim cos(x)/1 (x---> 0) = 1. I answered him “that is only a technic not a proof .To prove that derivative of sin(x) is equal to cos (x) ,it is necessary to know that lim sin(x)/x (x---> 0)=1,in other words in a logical ordering ,we can’t use Hopital’s law . Not only in this case but also generally we must be careful about logical ordering of mathematical predicates. ” http://www.merlot.org/merlot/viewMaterial.htm?id=720573 3 KS3 and KS4 mathematic lesson plans covering the following topics:KS3 - MEAN, MEDIAN, AND MODAL AVERAGES - Learners will be able to recognise the difference between different types of average, i.e. mean, median, and mode, and know how to calculate each variant accurately. They will be able to understand the statistical implications of the different types of average, and assess their usefulness/appropriateness in different situations.KS3 - PERCENTAGES - Learners will be able to calculate percentage decreases and increases.KS4 - AREA, PERIMETER AND VOLUME - Learners will be able to estimate/calculate the Area and Perimeter of 2D shapes and Volume of 3D shapes.Each 1 hour with a range of activities and national cirriculum level descriptors. http://www.merlot.org/merlot/viewMaterial.htm?id=346465 This report describes how students in the Mathematics Department in California State University, Long Beach (CSULB) were assessed, and the results used for further improvement in the department. http://www.merlot.org/merlot/viewMaterial.htm?id=618447 This is a lesson/unit plan for a high school geometry class investigating conditions leading to triangle congruence using Geometer's Sketchpad. Includes activities for students to investigate concepts in small groups, work as a class to formalize knowledge, and share learning with others. This was completed as an assignment for an educational technology course and the author has not used it in a classroom.
