Metacognitive components of the activity
Describing one's thoughts to another person requires the problem-solver to listen and attend to their own thoughts as well. The questions and clarifications that the listener describes is yet another window into the problem-solver's thinking.
Metacognitive goals for this activity:
Promote reflective thinking, communication skills, better reasoning, listening skills, and better problem-solving and conceptual understanding.
Assessing students' metacognition
There have been several studies of this instructional strategy. I have used it in my own instruction of mathematics and science for more than 25 years.

Lecture Objective: Students understand what “there ain't no such thing as a free lunch” really means. In other words, they can identify different types of nonmonetary compensation and how they form part of real wages.

The lesson incorporates two MRU videos about compensating wage differentials from our Principles of Microeconomics video course. We also mix in discussion prompts, exercises, practice questions, graphs and charts, and pre- and post-class assignments. Finally, we provide supplementary resources such as additional data sources, relevant news articles and blog posts, two episodes of Planet Money, and a podcast conversation between Tyler Cowen and Peter Thiel.

What is Marginal Revolution University (MRU)?

Many of us can remember our first great economics teacher who fundamentally changed how we see the world. At MRU, we try and deliver that experience to millions worldwide through video.

Founded as a nonprofit in 2012 by George Mason University economics professors Tyler Cowen and Alex Tabarrok, MRU is building the world’s largest online library of free economics education videos -- currently weighing in at more than 800 videos.

Again- this is activity that will set the stage for enriching the understanding of the nature of molecular motion and the affect of temperature on its rate as the students allow crystals to diffuse toward each other in a petri dish and form a precipitate.

Through class discussion and think-pair-share questions, this activity helps students come to understand the difference between emf and potential difference in electrical circuits. These concepts are broached within the context of internal resistance of batteries.

In this interactive lecture, models of the hydrogen atom are explored using an online Java applet. The exploration leads to qualitative and quantitative analysis of energy transitions.

The Spanish were savage and barbaric in Mexico… And the Conquest of the Mexica was extremely bloody. But it’s often told as ONLY the Spanish Vs. the Aztecs. And that’s not true… It’s not even close. The so called, “Conquest” of Mexico-Tenochtitlan was really a NATIVE REVOLT. It was ancient indigenous Mexicans against other Native Mexicans. Clearly… the Spanish were the main manipulators.

But it was Native Mexicans who organized, fought and overthrew: Mexico-Tenochtitlan. So much so…. That Native Mexicans accounted for 99% of all people who fought or assisted in the overthrow of the Aztecs, of Mexico-Tenochtitlan in 1521.

And… Who were the Indigenous Mexican allies of the Spanish? They were the Tabascans, the Cempoalans, Texcocans, the Totonacs, Huezotzingos, Chalcas, Quauhquecholtecas, the Zapotec, Mixtec, the Yope, the Xochilmcos, the Tlaxcalans, the Tarascans……And many….. Many….. more. And what did Native Allies provide a handful of Spanish….. Food….. Translation… Advice… Medical Assistance… Labor, especially porters… Housing… Clothing… Guides… Spies.. Messengers….Moral Support…Sex….. And …. Warriors to fight the Aztec and their allies. And much, much, more.

Now… this brief film isn’t a history of the so-called Spanish Conquest….. This is a history of the Native Revolt against Mexico-Tenochtitlan …… it’s a Native Revolution… As Cortes and about 500 Spaniards marched to Mexico-Tenochtitlan from the East… (their maximum number perhaps doubled). He was joined by hundreds of thousands of the largest and fiercest army ever assembled in Mesoamerica.

Students work on this Lecture Tutorial worksheet on ocean crust ages in groups during lecture. It directly confronts misconceptions students have about the patterns of ages of the ocean crust, and interpretations that can be made.

Enhanced lecture slides for Ch. 1-17 of the OpenStax Chemistry textbook. Ch. 1-6 are in their final version. Ch. 7-17 are still a rough copy, but the final versions will be uploaded as they are completed.

This write-pair-share activity presents Calculus III students with a worksheet containing several exercises that require them to find partial derivatives of functions of two variables. Afterwards, a series of Web-based animations are used to illustrate the surface of each function, the path of the indicated partial derivative for a specified value of the variable and the value of the derivative at each point along the path.

This activity is a field exploration where students observe, record and share their findings of plant and animal life on the prairie.

Students are asked to review a map of Southeast Asia and informational text about monsoons in Southeast Asia (The University of the State of New York, 2021), and then respond to the following prompts:
"Based on the map, associated text, and your knowledge of Earth Science, click on a location in Southeast Asia that is most likely to have a regional low pressure condition during July."
"Based on the map, associated text, and your knowledge of Earth Science, drag the small yellow circle to a location in Southeast Asia that is most likely to have a regional low pressure condition during July."

In principles of economics students many times have trouble understanding the concept of opportunity cost, connecting opportunity cost to comparative advantage, and differentiating between absolute advantage and comparative advantage. This activity allows the instructor to detect whether a large number of students exhibit any of these misconceptions, and then focus on the most problematic concepts in class.

Gravitation introductory activity with interesting animation. The activity allows the student to revile the connection between the initial speed and the shape of satellite orbit.

Secondary Math Ed majors or Geometry students are directed to a Web site where they read through a rich and extensive collection of proofs of the Pythagorean Theorem, some accompanied by Java applets. Each student then selects two proofs to prepare to present to the class-a geometric proof and a visual proof-and writes a detailed outline of each proof. The student also indicates one additional proof that was of particular interest and the reason(s) for its selection.

Here is an exercise to acquaint students with pressure-temperature diagrams related to Earth's interior, teach why the mantle melts in the context of pressure and temperature, demonstrate the role water has on melting, and review the three ways to melt the mantle.
