The Flaws of Averages
Conditions of Use:
Remix and Share
Rating

This learning video presents an introduction to the Flaws of Averages using three exciting examples: the ''crossing of the river'' example, the ''cookie'' example, and the ''dance class'' example. Averages are often worthwhile representations of a set of data by a single descriptive number. The objective of this module, however, is to simply point out a few pitfalls that could arise if one is not attentive to details when calculating and interpreting averages. The essential prerequisite knowledge for this video lesson is the ability to calculate an average from a set of numbers. During this video lesson, students will learn about three flaws of averages: (1) The average is not always a good description of the actual situation, (2) The function of the average is not always the same as the average of the function, and (3) The average depends on your perspective. To convey these concepts, the students are presented with the three real world examples mentioned above.

هل الأكبر أفضل؟ إلقي نظرة على التحيز في الاختيارالموجود في كل مكان حولنا

يتناول هذا الفيديو التعليمي مشكلة معينة من التحيز في الاختيار، هي وجود التحيز الإحصائي حيث يوجد خطأ في اختيار الأفراد أو الجماعات لإجراء استدلالات أوسع. بدلا من الخوض في هذا الموضوع العريض عبر الإحصاءات الرسمية، نحن نحقق في كيفية ظهورها في حياتنا اليومية، أحيانا تشويه تصوراتنا عن الناس , الأماكن والأحداث، ما لم نكن حذرين. عند اختيار الناس عشوائيا من مجموعتين من أحجام مختلفة، أغلب الذين تم انتقاؤهم عادة ما يأتون من المجموعة الأكبر. هذا يعني أننا سنسمع أكثر عن تجربة المجموعة الأكبر عن المجموعة الأصغر. هذا ليس دوما أمرا سيئا، ولكنه ليس دوما أمرا جيدا على حد سواء. لأن الجماعات الكبيرة'' تتحدث بصوت أعلى،'' علينا أن نكون حذرين عندما نكتب الصيغ الرياضية حول ما حدث في المجموعتين. نحن نفكر بهذه المسألة في هذا الفيديو، مع أمثلة تنطوي مسارح وحافلات، وليمون. ان الشرط الأساسي لهذا الدرس بالفيديو هو الإلمام بالجبر. سيستغرق حوالي ساعة واحدة ليكتمل، والمواد الوحيدة المطلوبة هي السبورة والطباشير.

Phylogenetics
Rating

This activity lets learners participate in the process of reconstructing a phylogenetic tree and introduces them to several core bioinformatics concepts, particularly in relation to evolution. Groups of learners (at least 10) repeat a secret message (five to seven similar-sounding words) like the game "Telephone". In this version of the game, however, learners write and then code what they hear, creating a model of a phylogenetic tree and using a species distance matrix. This resource includes background information about phylogenetic trees, maximum parsimony, and matrix theory (see page 6-7 of PDF).

In this activity related to computer programming, learners give directions to a "robot" (either an adult or another learner) and find out which instructions the robot is able to follow, and how their instructions are taken literally. This activity will simulate how computers follow instructions very precisely, which can be frustrating at times. This activity also helps learners understand instruction set size (large complex vs. small efficient).

Learners compare a life-size drawing of a Tyrannosaurus rex head and a full-size Sinornithosaurus body to understand that dinosaurs varied in size. Learners trace individual pieces of a dinosaur on paper and then work together as a group to arrange the pieces of the "puzzle". This is an opportunity to understand scale drawings as well as learn how to work as a group.

Understanding Science: How science really works
Rating

The mission of Understanding Science is to provide a fun, accessible, and free resource that accurately communicates what science is and how it really works. The process of science is exciting, but standard explanations often miss its dynamic nature. Science affects us all everyday, but people often feel cut off from science. Science is an intensely human endeavor, but many portrayals gloss over the passion, curiosity, and even rivalries and pitfalls that characterize all human ventures. Understanding Science gives users an inside look at the general principles, methods, and motivations that underlie all of science. This project has at its heart a re-engagement with science that begins with teacher preparation and ends with broader public understanding. Its immediate goals are to (1) improve teacher understanding of the nature of the scientific enterprise, (2) provide resources and strategies that encourage and enable K-16 teachers to reinforce the nature of science throughout their science teaching, and (3) provide a clear and informative reference for students and the general public that accurately portrays the scientific endeavor. The Understanding Science site was produced by the UC Museum of Paleontology of the University of California at Berkeley, in collaboration with a diverse group of scientists and teachers, and was funded by the National Science Foundation1. Understanding Science was informed and initially inspired by our work on the Understanding Evolution project, which highlighted the fact that many misconceptions regarding evolution spring from misunderstandings of the nature of science. Furthermore, research indicates that students and teachers at all grade levels have inadequate understandings of the nature and process of science, which may be traced to classrooms in which science is taught as a simple, linear, and non-generative process. This false and impoverished depiction disengages students, discourages public support, and may help explain current indications that the U.S. is losing its global edge in science. Even beyond the health of the U.S. economy, the public has a genuine need to critically assess conflicting representations of scientific evidence in the media. To do this, they need to understand the strengths, limitations, and basic methods of the enterprise that has produced those claims. Understanding Science takes an important step towards meeting these needs.

Using Geometry to Design Simple Machines
Conditions of Use:
Remix and Share
Rating

This video is meant to be a fun, hands-on session that gets students to think hard about how machines work. It teaches them the connection between the geometry that they study and the kinematics that engineers use -- explaining that kinematics is simply geometry in motion. In this lesson, geometry will be used in a way that students are not used to. Materials necessary for the hands-on activities include two options: pegboard, nails/screws and a small saw; or colored construction paper, thumbtacks and scissors. Some in-class activities for the breaks between the video segments include: exploring the role of geometry in a slider-crank mechanism; determining at which point to locate a joint or bearing in a mechanism; recognizing useful mechanisms in the students' communities that employ the same guided motion they have been studying.
