In this activity on page 1 of the PDF, learners compare the relative sizes of biological objects (like DNA and bacteria) that can't be seen by the naked eye. Learners will be surprised to discover the range of sizes in the microscopic world. This activity can be followed up with a second activity, "What's in a microbe?", located on page 3 in the same resource.

The aim of the Portfolio Seminar is to assist in developing a critical position in relationship to their design work. By engaging multiple forms of representation, written and visual, students will explore methods that facilitate describing and representing their design work. Through a critical assessment of their existing portfolios, students will first be challenged to articulate design theses and interests in their past projects. Different mediums of representation will then be studied in order to hone an understanding of the relationship between form and content, and more specifically, the understanding of particular modes of representation as different filters through which their work can be read. Some of the questions that will be addressed are:

How does one go about describing an image?
How does one theorize representation?
How does one articulate a design thesis in writing verses visual media?
How can the two interact to enhance each other?
How do different media, printed verses web publishing, affect the representation of work?
How is your work best communicated?

6.867 is an introductory course on machine learning which gives an overview of many concepts, techniques, and algorithms in machine learning, beginning with topics such as classification and linear regression and ending up with more recent topics such as boosting, support vector machines, hidden Markov models, and Bayesian networks. The course will give the student the basic ideas and intuition behind modern machine learning methods as well as a bit more formal understanding of how, why, and when they work. The underlying theme in the course is statistical inference as it provides the foundation for most of the methods covered.

Repeated motion is present everywhere in nature. Learn how to 'make waves' with your own movements using a motion detector to plot your position as a function of time, and try to duplicate wave patterns presented in the activity. Investigate the concept of distance versus time graphs and see how your own movement can be represented on a graph.

This lesson unit is intended to help you assess how well students are able to: Calculate the mean, median, mode, and range from a frequency chart; and to use a frequency chart to describe a possible data set, given information on the mean, median, mode, and range.

In this course students create digital visual images and analyze designs from historical and theoretical perspectives with an emphasis on art and design, examining visual experience in broad terms, and from the perspectives of both creators and viewers. The course addresses key topics such as: image making as a cognitive and perceptual practice, the production of visual significance and meaning, and the role of technology in creating and understanding digitally produced images. Students will be given design problems growing out of their reading and present solutions using technologies such as the Adobe Creative Suite and/or similar applications.

Whole numbers are no better than any others! Practice plotting values on the number line as a passionate activist rises up and demands equity for all numbers, including fractions and decimals.

Provides a comprehensive introduction to key issues and findings in object recognition in experimental, neural, computational, and applied domains. Emphasizes the problem of representation, exploring the issue of how 3-D objects should be encoded so as to efficiently recognize them from 2-D images. Second half focuses on face recognition, an ecologically important instance of the general object recognition problem. Describes experimental studies of human face recognition performance and recent attempts to mimic this ability in artificial computational systems.

The representation depicts food webs for three different marine environments: deep sea, coral reef and continental shelf. Students are given directions and clues and then asked to pick the organism that answers the clues. They keep following the clues until all organisms in the ecosystems are connected. At this point the food web is displayed.

Original Études for the Developing Conductor is a collection of supplemental études designed to enhance contemporary conducting pedagogy by amplifying the voices of composers from historically excluded groups. Each étude was commissioned from and composed by a living composer, the majority of whom are woman-identifying composers and/or composers of color. Each étude also addresses multiple specific pedagogical goals common to all conducting classrooms.

Conducting textbooks commonly include musical examples to expose student conductors to various musical challenges and situations. However, due to the relative ease of using only music from the public domain, most examples found in commercially published books are excerpts of larger works composed by deceased cisgender white men of European descent. Often, this music bears little relation to a significant portion of the music contemporary students engage with and perform. These excerpts also tend to be quite short (i.e., less than a minute) and do not create cohesive, self-contained musical arcs.

Two besotted rulers must embrace proportional units in order to unite their lands. It takes mathematical reasoning to identify the problem, and solution, when engineers from Queentopia and Kingopolis build a bridge to meet in the middle of the river.

This lesson explores several strands of the musical "DNA" that make up the beat of popular music. Looking to the past, this lesson asks what it means to call music "Afro-Cuban" "Afro-Caribbean," or more broadly, "African-American." Students will use Soundbreakingclips of Santana and Beyonce and the Soundbreaking Rhythmic Layers TechTools to locate in American popular music influences stemming from the African-American church, Latin America and West Africa. Students will then explore the ways "the beat" of this music has, to some listeners, been perceived as "dangerous" while, for others, it is believed that music has been able to challenge obstacles of racism and segregation, bringing people from varied ethnic groups and lifestyles together in ways that words and laws could not.

This interactive Flash animation allows students to explore size estimation in one, two and three dimensions. Multiple levels of difficulty allow for progressive skill improvement. In the simplest level, users estimate the number of small line segments that can fit into a larger line segment. Intermediate and advanced levels offer feature games that explore area of rectangles and circles, and volume of spheres and cubes. Related lesson plans and student guides are available for middle school and high school classroom instruction. Editor's Note: When the linear dimensions of an object change by some factor, its area and volume change disproportionately: area in proportion to the square of the factor and volume in proportion to its cube. This concept is the subject of entrenched misconception among many adults. This game-like simulation allows kids to use spatial reasoning, rather than formulas, to construct geometric sense of area and volume. This is part of a larger collection developed by the Physics Education Technology project (PhET).

This fun Web article is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they learn about the Earth's outer shell and its constant movement. It begins with an overview that explains tectonic plates. There is an animation that shows recent earthquakes and their relationship to plate boundaries. Students can click to explore 12 individual volcanoes, mountains, hotspots, and earthquakes. For each of the geological formations or events, they will see a map that shows how the plates are moving, an animation about plate interaction, stats, and a story about that particular formation or event.

In this activity, learners work in groups to determine the mass and volume of four samples: glass marbles, steel washers or nuts, pieces of pine wood, and pieces of PVC pipe. Learners then plot the data points on a large class graph of mass vs. volume to discover that data points for a particular material form a straight line, the slope of which gives the density of the material.

Ratey pops up when you least expect him. And he can't resist pointing out the rates and "purrportions" in daily life. It turns out that everyday decisions rely on mathematical reasoning about rates.

This is a textbook that was originally designed for a 3000-level large lecture course on “Rhetorical Theory” at the University of Minnesota, Twin-Cities. An interdisciplinary tradition, rhetorical theory describes how speech, representation, and power are managed by techniques and technologies of communication. The plan of this book moves from rhetoric as an art of speech to rhetoric as a technology of power. The early chapters provide definitions and context for rhetoric as speech, middle chapters (e.g., on signs, symbols, visual images, argumentation, and narrative) describe rhetoric as representation, and the concluding chapters (e.g., on settler colonialism, secrecy, and digital rhetoric) elaborate on rhetoric as a technology of power. Of course, there is considerable overlap across these areas: the chapter on “rhetoric and ideology” sets the stage for later understandings of rhetoric as power; the chapter on “the rhetorical situation” hearkens back to the introductory understanding of rhetoric as speech. The book includes (audio and/or video) recordings with each chapter, as well as guidelines for proposed written assignments. Students using this resource should gain a thorough understanding of what rhetoric is, how it was practiced historically and today, and the ways that rhetoric wields an invisible influence over contemporary public and political life. Additionally, this book is designed for use across a variety of modalities, including in-person, online (synchronous/asynchronous), and hybridized formats. Additional resources (PowerPoint slides, quiz/exam questions) are also available to confirmed instructors upon request.

This course provides resources for faculty interested in incorporating more diverse and inclusive materials in their teaching materials and research. It contains pages for a variety of STEM disciplines that can be used as micro-lessons in disciplinary course. It also contains a module on finding and using diverse materials and a module on representation in special topics related to STEM such as laboratories, inclusive teaching and STEM Librarianship.

Who can put things right? Superheroine Scale Ella uses the power of scale factor to foil the villain.

Millions of people are on-line today and the number is rapidly growing - yet this virtual crowd is often invisible. In this course we will examine ways of visualizing people, their activities and their interactions. Students will study the cognitive and cultural basis for social visualization through readings drawn from sociology, psychology and interface design and they will explore new ways of depicting virtual crowds and mapping electronic spaces through a series of design exercises.
