Are Random Triangles Acute or Obtuse?
Conditions of Use:
Remix and Share
Rating

This learning video deals with a question of geometrical probability. A key idea presented is the fact that a linear equation in three dimensions produces a plane. The video focuses on random triangles that are defined by their three respective angles. These angles are chosen randomly subject to a constraint that they must sum to 180 degrees. An example of the types of in-class activities for between segments of the video is: Ask six students for numbers and make those numbers the coordinates x,y of three points. Then have the class try to figure out how to decide if the triangle with those corners is acute or obtuse.

The Broken Stick Experiment: Triangles, Random Numbers and Probability
Conditions of Use:
Remix and Share
Rating

This learning video is designed to develop critical thinking in students by encouraging them to work from basic principles to solve a puzzling mathematics problem that contains uncertainty. Materials for in-class activities include: a yard stick, a meter stick or a straight branch of a tree; a saw or equivalent to cut the stick; and a blackboard or equivalent. In this video lesson, during in-class sessions between video segments, students will learn among other things: 1) how to generate random numbers; 2) how to deal with probability; and 3) how to construct and draw portions of the X-Y plane that satisfy linear inequalities.

With your mouse, drag data points and their error bars, and watch the best-fit polynomial curve update instantly. You choose the type of fit: linear, quadratic, cubic, or quartic. The reduced chi-square statistic shows you when the fit is good. Or you can try to find the best fit by manually adjusting fit parameters.

يعرض هذا الفيديو التعليمي مقدمة للعيوب التي تشوب المتوسطات باستخدام ثلاثة أمثلة مثيرة: '' عبور النهر'' كمثال، ملف تعريف الارتباط'''' كمثال، "فصل الرقص'' كمثال. ان المتوسطات غالبا ما تكون مفيدة عند تمثيل مجموعة من البيانات من قبل رقم وصفي واحد. ان الهدف من هذه الوحدة النمطية، مع ذلك، هو الاشارة ببساطة إلى عدد قليل من العثرات التي قد تنجم إذا لم يكن الطالب يقظا إلى التفاصيل عند حساب وتفسير المتوسطات. ان المعرفة الأساسية المسبقة لدرس الفيديو هو القدرة على حساب المتوسط ​​من مجموعة من الأرقام. سوف يتعلم الطلاب خلال الدرس الفيديو، ثلاثة شوائب للمتوسطات: (1) ان المتوسط ​​ليس دائما وصفا جيدا للوضع الفعلي، (2) ان وظيفة المتوسط ليست دائما مماثلة لمتوسط الدالة، و (3) يعتمد المتوسط على المنظور الخاص بك. لنقل هذه المفاهيم، يتم تعريف الطلاب بأمثلة العالم الحقيقي الثلاثة المذكورة أعلاه.

Free Fall
Conditions of Use:

This video lesson is an example of ''teaching for understanding'' in lieu of providing students with formulas for determining the height of a dropped (or projected) object at any time during its fall. The concept presented here of creating a chart to organize and analyze data collected in a simple experiment is broadly useful. During the classroom breaks in this video, students will enjoy timing objects in free fall and balls rolling down ramps as a way of learning how to carefully conduct experiments and analyze the results. The beauty of this lesson is the simplicity of using only the time it takes for an object dropped from a measured height to strike the ground. There are no math prerequisites for this lesson and no needed supplies, other than a blackboard and chalk. It can be completed in one 50-60-minute classroom period.

This video lesson uses the technique of induction to show students how to analyze a seemingly random occurrence in order to understand it through the development of a mathematical model. Using the medium of a simple game, Dr. Lodhi demonstrates how students can first apply the 'rules' to small examples of the game and then, through careful observation, can begin to see the emergence of a possible pattern. Students will learn that they can move from observing a pattern to proving that their observation is correct by the development of a mathematical model. Dr. Lodhi provides a second game for students in the Teacher Guide downloadable on this page. There are no prerequisites for this lesson and needed materials include only a blackboard and objects of two different varieties - such as plain and striped balls, apples and oranges, etc. The lesson can be completed in a 50-minute class period.

Interpreting Statistics: A Case of Muddying the Waters
Rating

This lesson unit is intended to help teachers assess how well students are able to: interpret data and evaluate statistical summaries; and critique someone elseŐs interpretations of data and evaluations of statistical summaries. The lesson also introduces students to the dangers of misapplying simple statistics in real-world contexts, and illustrates some of the common abuses of statistics and charts found in the media.
