Essential Science for Teachers: Physical Science: Session 2. The Particle Nature of Matter: Solids,
In-depth interviews with children that uncover their ideas about the topic at hand.,This segment provides an example of probing questions and phenomena used to elicit the student's ideas about motion of particles in a liquid. The student has several ideas about why the particles move including bubbles that popped, pressure, "commotion," waves, etc. but seems to lack the idea that the particles in a liquid have greater energy, hence more motion. The interviewer probes further to find out if the s
Patrons d'exercices pour Aplusix Une étape du développement de l'EIAH occasion d'un travail entre
Au cours du développement de l'EIAH APLUSIX, il y a eu de nombreuses occasions d'un travail partagé entre informaticiens et didacticiens. Quelques-unes sont décrites succinctement. Lors de la mise en place de patrons d'exercices et d'une carte de tests, une coopération plus approfondie a eu lieu, en respectant les disciplines de chacun. Cette mise en place de patrons d'exercices est décrite plus longuement.,Preprint
Learning and teaching with educational technologies.
This chapter considers what we have learned about learning and teaching with educational technologies over the past several decades. While there are compelling data and arguments on the positive effects of these tools, there are also well-documented difficulties with implementing such innovations. The social contexts of the uses of technology are crucial to understanding how technology may influence teaching and learning. The classroom influences, in particular the teacher, are seminal. Much mor
Art in Engineering - Moving Art
Students learn how forces are used in the creation of art. They come to understand that it is not just bridge and airplane designers who are concerned about how forces interact with objects, but artists as well. As “paper engineers,” students create their own mobiles and pop-up books, and identify and use the forces (air currents, gravity, hand movement) acting upon them.

the demonstration was for that day over. In a few
minuts, however, our pickets commenced a rapid
musketry fire on the extreme left, they soon came
hurring back to the lines, and in a moment the
rebels, massed in tremendous columns rushed
with loud cheers up on the 3rd Corps, commanded
by Sickles. Bravely did these gallant veterans meet
and with the timely assistance of other forces, this
part of the line was made as strong as a mountain,
which all desperate ener
Beem Letter, December 1861

this disappointment will be followed by happier events. Let us
hope for the best, and although it may seem hard now, I doubt
not it will be much brightter for us both in the future.
I am very sorry that I did not get your letter a little sooner.
Supposing that your answer to my letter in which I spoke
about your meeting me at Wheeling would not reach me, I
wrote a similar letter a short time ago, which you will
likely get before this reaches you. But as you think best
