Filtering is the process of removing or separating the unwanted part of a mixture. In signal processing, filtering is specifically used to remove or extract part of a signal, and this can be accomplished using an analog circuit or a digital device (such as a computer). In this lesson, students learn the impact filtering can have on different types of signals, the concepts of frequency and spectrum, and the connections these topics have to real-world signals such as musical signals. Students also learn the roles that these concepts play in designing different types of filters. The lesson content prepares students for the associated activity in which they use an online demo and a variety of filters to identify the message in a distress signal heavily corrupted by noise.

Students learn the basic principles of filtering as well as how to apply digital filters to extract part of an audio signal by using an interactive online demo website. They apply this knowledge in order to isolate a voice recording from a heavily noise-contaminated sound wave. After completing the associated lesson, expect students to be able to attempt (and many successfully finish) this activity with minimal help from the instructor.

We plan to facilitate several engineering lessons that requires students to design, build ROV controllers, calculate weight, underwater thrust and buoyancy.

This course introduces the core theory of modern financial economics and financial management, with a focus on capital markets and investments. Topics include functions of capital markets and financial intermediaries, asset valuation, fixed-income securities, common stocks, capital budgeting, diversification and portfolio selection, equilibrium pricing of risky assets, the theory of efficient markets, and an introduction to derivatives and options.

Each session involves class discussion, some centered on lectures and others around business cases.

This book is suitable for an undergraduate or MBA level Financial Accounting course.

The authors bring their collective teaching wisdom to bear in this book not by changing "the message"(financial accounting content), but by changing "the messenger" (the way the content is presented). The approach centers around utilizing the Socratic method, or simply put, asking and answering questions. The reason that this approach continues to be glorified after thousands of years is simple - it engages students and stresses understanding over memorization. So this text covers standard topics in a standard sequence, but does so through asking a carefully constructed series of questions along with their individual answers.

This simple-looking problem reveals much about how well students understand unit fractions as well as representing fractions on a number line.

In this activity students will learn the basic concept of Global Positioning Systems (GPS) using triangulation and measurement on a small scale in the classroom. Students discover how GPS and navigation integrate mathematic and scientific concepts to create a standard for locating people and objects. This activity helps students understand both the need for and methods of navigation.

If you haven’t discovered already, there are myriad open resources that exist. Often the trouble lies in locating those that fit precisely what you need. We’ve broken down these resources with the intent of making the search process more efficient and effective. For each you’ll find a list of unique traits, licensing information, and an example of how to attribute the source. Click one of the media sources in the Find Resources sub-menu for the details.

Students create their own simple compasses using thread, needle and water in a bowl and learn how it works.

The purpose of this task is to have students work on a sequence of area problems that shows the advantage of increasingly abstract strategies in preparation for developing general area formulas for parallelograms and triangles.

We use digital media every day, from texting, streaming TV shows, and gaming all the way to using voice assistants or ordering our food online. For today's kids, it's a lot more than just "screen time." So how can we help students balance their online and offline lives? It starts with recognizing just how much media we use.

This task asks students to find and use two different common denominators to add the given fractions. The purpose of this question is to help students realize that they can use any common denominator to find a solution, not just the least common denominator.

This task asks students to use two different denominators to subtract fractions. The purpose of this is to help students realize that any common denominator will work, not just the least common denominator.

The web is full of questionable stuff, from rumors and inaccurate information to outright lies and so-called fake news. So how do we help students weed out the bad and find what's credible? Help students dig into why and how false information ends up online in the first place, and then practice evaluating the credibility of what they're finding online.
