Diagnostic et aide dans un environnement d'apprentissage ouvert : Un exemple en chimie, SCHNAPS
Cet article présente la conception et la réalisation d'un environnement ouvert pour l'apprentissage de la résolution de problèmes en chimie. Trois questions principales y sont étudiées : les outils mis à la disposition de l'élève, l'analyse de son activité et les aides que le système est en mesure de lui apporter. La conception de ces trois composantes de l'environnement s'appuie sur des analyses préalables des difficultés rencontrées, des formes de résolution des élèves et des
Metamorphosis — Stories of Change
The goal of this activity is for students to learn how to tell a story in order to make a complex topic (such as global warming or ozone holes) easier for a reader to grasp. Students realize that the narrative impulse underlies even scientific and technical writing and gain a better understanding of the role of myth as a “science” of imagination that helps us to gain insight into human motivation.
Students learn how a bill becomes law in the U.S. Congress and research legislation related to global warming.

Eastman Jazz: Two Ways to the Same Stage
Each spring, two of the big bands at Eastman, the Eastman Jazz Ensemble and the Eastman New Jazz Ensemble, put together a split concert that they perform in Kilbourn Hall. While the two bands have a similar makeup in terms of the size of the group and the instruments, they each take a very different approach to the music that they will play on the very same stage. While the Eastman New Jazz Ensemble is known for playing newer music, the approach of ensemble director Dave Rivello is a rather tra
Students will learn the difference between global, prevailing and local winds. In this activity, students will make a wind vane out of paper, a straw and a soda bottle and use it to measure wind direction over time. Finally, they will analyze their data to draw conclusions about the prevailing winds in their area.
Dripping Wet or Dry as a Bone?
Students use a sponge and water model to explore the concept of relative humidity and create a percent scale.

Rose Bowl : can a football team score 11 points in a game?
This activity uses the history of the Rose Bowl football tournament to examine numerical combinations. It asks the student how many different ways a football team can end a game with 11 points, something that has never happened in Rose Bowl history. The activity, part of the Figure This! collection of 80 math challenges emphasizing math in the real world, also considers possible numerical combinations for playing darts and introduces the concept of a perfect number. It suggests that students mak
Putt-putt golf : can you make a hole-in-one?
This activity opens with an animation of a miniature golf course that shows how a player would make a hole-in-one by bouncing the golf ball off the wall of the course. Given that the angle of incidence will be equal to the angle of reflection, students are challenged to determine the point along the wall where the ball should be aimed. This activity, part of the Figure This! collection of 80 math challenges emphasizing math in the real world, explains how the method of reflecting is used by astr
Superspace: One Thousand and One Lessons in Supersymmetry
We introduce superfields in chapter 2 for the simpler world of three spacetime dimensions, where superfields are very similar to ordinary fields. We skip the discussion of nonsuperspace topics (background fields, gravity, etc.) which are covered in following chapters, and concentrate on a pedagogical treatment of superspace. We return to four dimensions in chapter 3, where we describe how supersymmetry is represented on superfields, and discuss all general properties of free superfields (and the

The Meaning of Translational Research and Why It Matters
Translational research means different things to different people, but it seems important to almost everyone. The National Institutes of Health (NIH) has made translational research a priority, forming centers of translational research at its institutes and launching the Clinical and Translational Science Award (CTSA) program in 2006. With 24 CTSA-funded academic centers already established, other universities are transforming themselves to compete for upcoming CTSA grants. By 2012, the NIH expe

Moving learning games forward
The notion of using video games for learning causes some to cringe, others to leap for joy, and many to ask questions about this learning medium. These questions often come from people and organizations that are considering delving into the world of learning games but dont know if this is advisable or dont know where to start. The goal of this paper is to answer those questions about learning games and to help plot a path for people and organizations interested in developing or fostering the
Combing the Evidence for Support of Lab-based Screening Tests: An Update From the US Preventive Serv
The use of evidence-based guidelines is gaining renewed interest as an approach toward the rational use of health care dollars in Europe and the US. This lecture will focus on how the US Preventive Services Task force, a national independent body of primary experts sponsored by the Agency for Healthcare Quality and Research, uses evidence-based approaches in making its recommendations regarding screening tests for the US population. We will focus on the recent controversies around recommendation
