Written for introductory education research courses, this book gives students a broad view of the process, history, paradigms, and methods of education research so that they can become critical consumers of others' research, communicate in a variety of research languages, and navigate dominant research paradigms throughout their careers.

"This unit launches with students hearing about an injury that happened to a middle school student that caused him to need stitches, pins, and a cast. They analyze doctor reports and develop an initial model for what is going on in our body when it heals. Students investigate what the different parts of our body are made of, from the macro scale to the micro scale. They figure out parts of our body are made of cells and that these cells work together for our body to function. Once students have figured out what their bodies are made of and how the parts of their body work together to be able to move, they wonder how the parts of our body heal. They start by watching a timelapse of a knee scrape and notice that over time the part that was scraped is filled in with new skin cells. Students investigate what happens when cells make more cells, what cells need to make more cells, and how cells get what they need to make more cells. Students return to the healing timeline they made at the start of the unit and apply what they have figured out about the interactions between the different systems in the body to explain the various events of healing that took place for the injury at the start of the unit. Finally, they apply their model for healing to explain growth at growth plates in children's bodies as they become adults." The material is distributed in accordance with the CC BY.

Have you ever had a clock or other device stop working? What happened to make it stop working? In this unit, students make observations of a winding clock and a plug-in clock and consider the similarities and differences in what makes the two turn on and stay on. From there, the unit supports students in developing ideas about energy transfer by electrical currents as they go on school tours, take apart devices, and build simple circuits. Students also notice that some devices we use to tell time always know what time it is, and some have to be set by hand, which leads us to wonder how devices are designed to communicate and receive information. Students engage in an engineering design project about information and energy transfer and learn about how criteria and constraints shape designs. Unit investigations also help students understand that we generate electricity from renewable and nonrenewable resources. To end the unit, students apply all the ideas they have learned to design a Martian space rover that we power and can communicate with from Earth.
