Essential Science for Teachers: Physical Science
In-depth interviews with children that uncover their ideas about the topic at hand.,The segment shows the interviewer helping the student think about the gas formed after materials are mixed together and whether it is a different substance. The interviewer refers back to a model represented by unifix cubes to help the student realize there is a new substance in the gas form captured from the reaction. The interviewer has the student test this by smelling the gas.

In-depth interviews with children that uncover their ideas about the topic at hand.,The segment demonstrates ways to help students clearly tell what their ideas are about science and how they develop their ideas.
Essential Science for Teachers: Physical Science Session 3. Physical Changes and Conservation of Mat
What happens when sugar is dissolved in a glass of water or when a pot of water on the stove boils away? Do things ever really "disappear"? In everyday life, observations that things "disappear" or "appear" seem to contradict one of the fundamental laws of nature: matter can be neither created nor destroyed. In this session, participants learn how the principles of the particle model are consistent with conservation of matter.,The segment shows the interviewer trying to find out the student's id

Essential Science for Teachers: Physical Science
In-depth interviews with children that uncover their ideas about the topic at hand.,In this segment the interviewer uses a model to represent what is happening when substances dissolve in water, as well as a representation of two different solutions. The interviewer then asks for a prediction of what would happen when two clear solutions are mixed together. The interviewer uses the model to help the student build an understanding of what happened to form the precipitate. The student also changed
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 an example of the interviewer having the student use before and after drawings to show how the mountain was different millions of years ago. The student mentions the mountain is higher and when asked why, she mentions "pushing". The segment shows how the interviewer probes further to find out what she means by "pushing" and what causes the oush. The student continues to use her idea of water cu

I'm Watching You 24/7
The post-Renaissance world saw the nation-state mature and confront the issue of how to control the lives of its citizens. Two models of political organization, democratic and authoritarian, gradually developed. During the twentieth century, as some nations granted individuals and groups more and more rights, ideology and modern technology enabled authoritarian governments to gain ever more control, until community interest dominated the individual and totalitarianism was born. Although Nazi Ger
Girls Speak Out
Today, over 115 million children have never set foot inside a school. The fact is that for children living in developing countries, the dream of a first day of school is yet to be realized. The daily realities of poverty, political instability, regional conflict, geography, and cultural or traditional values all play a role to varying degrees -- and the issue of gender disparity makes this fact even more staggering. Full and equal access to education (Article 26) as outlined in the 'Universal De
Essential Science for Teachers: Earth and Space Science
In-depth interviews with children that uncover their ideas about the topic at hand.,The interview probes to find out prerequisite ideas about how mountains formed before probing for more sophisticated ideas about plate movement. The student shows she has some idea of the involvement of volcanoes and earthquakes but further probing reveals a limited understanding of their role.

Essential Science for Teachers: Earth and Space Science
In-depth interviews with children that uncover their ideas about the topic at hand.,The interviewer is trying to find out the students' ideas about how moutains and volcanoes form. The student demonstrates her thinking by pushing 2 sheets of paper together, showing her ideas about uplifting of mountains. She seems to have a basic notion of plates and what happens when plates collide although it is too simplistic for the benchmark.

Hitler's Germany
Hitler's Germany, or from here on out referred to as 'The Third Reich', is a course that will familiarize the student with key themes in the current historical literature involving the subject. The course breaks down to several weeks of discussion held on the main page and a paper that each student will complete on a topic of their choosing, which will then be critiqued by the class for its merit and historical content. The student taking this class will hopefully walk away with a greater unders

In-depth interviews with children that uncover their ideas about the topic at hand.,In this segment the interviewer is using questions to help guide the student's thinking about the difference in age between two mountains. He encourages her to look at her own drawing and compare what she has drawn to a representation of two mountains encountered earlier. The student changes her idea about which mountain is older by connecting the explanation she used in her own drawing to the representations use
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.,The interviewer probes to find out if the student thinks atoms in a gas move. The student has the idea that gas atoms move freely but is limited by a model in which there are no boundaries. When presented with the phenomenon of air in a sealed bag, the student says they would stop because of the boundary. The student goes on to reason by use of an analogy that at recess time when you are free to go where ever you
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
