Essential Science for Teachers: Earth and Space Science
In-depth interviews with children that uncover their ideas about the topic at hand.,In this segment the interviewer uses a series of probing questions to ask the student to explain terms she has used such as "evaporate," "water vapor," and "steam." The segment shows that while the student may use these terms, she may not understand their meaning and has some naive ideas about the difference between water vapor and liquid water.

Essential Science for Teachers: Earth and Space Science
In-depth interviews with children that uncover their ideas about the topic at hand.,When Emily makes a statement about salt being in water, the interviewer probes further to find out her ideas about rain and the water cycle. She has some correct ideas about the water evaporating from oceans and coming down again as rain but has the incorrect notion that the salt evaporates with the water. He tries to challenge her thinking by having her think about familiar phenomena like tasting the salt in oce

Essential Science for Teachers: Earth and Space Science
In-depth interviews with children that uncover their ideas about the topic at hand.,The interviewer wants to find out a student's ideas about how wind and rain can break rock. The student draws a picture of a mountain and the interviewer asks her to talk about it. This strategy helps teachers see how asking students to draw their ideas may bring out students' ideas.

Essential Science for Teachers: Earth and Space Science
In-depth interviews with children that uncover their ideas about the topic at hand.,This segment shows examples of probes used to elicit ideas about the wearing down of mountains and how the appearance of a mountain is an indication of its age. The interviewer uses a series of questions to elicit explanations of why the two pictures of mountains are different and when the student uses terms like "worn down," he probes further to find out what she means by that, eliciting ideas about weathering.

In-depth interviews with children that uncover their ideas about the topic at hand.,The interviewer shows the student two different representations of mountains, one smooth and one jagged, and asks her to describe what she sees. As she describes a volcano, the interviewer probes to find out why she thinks it is a volcano, whether a volcano is a mountain, and how a volcano forms a mountain.

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.,In this segment the interviewer probes the student's ideas about the arrangement and motion of particles in the 3 states of matter. When asked if atoms move, the student says in air they do but in aluminum they don't. When asked to draw, the student uses "dots" with gases spread far out, liquids closer together, and in solids he shades the picture to show that it is contiguous.

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

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.

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.

Beem Letter, July 1863 (page 2)

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,

Beem Letter, December 1861 (page 2)
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
