Use tiles to represent variables and constants, learn how to represent and solve algebra problems. Solve equations, substitute in variable expressions, and expand and factor. Flip tiles, remove zero pairs, copy and arrange, and make your way toward a better understanding of algebra.
An interactive applet and associated web page that demonstrate how to find the perpendicular distance between a point and a line using trigonometry, given the coordinates of the point and the slope/intercept of the line. The applet has a line with sliders that adjust its slope and intercept, and a draggable point. As the line is altered or the point dragged, the distance is recalculated. The grid and coordinates can be turned on and off. The distance calculation can be turned off to permit class exercises and then turned back on the verify the answers. The applet can be printed as it appears on the screen to make handouts. The web page has a full description of the concept of the concepts, a worked example and has links to other pages relating to coordinate geometry. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.
This course covers the major topics of mechanics, including momentum and energy conservation, kinematics, NewtonŰŞs laws and equilibrium. The major emphasis is to develop critical analysis, problem solving and scientific reasoning skills by considering numerous different systems and interactions, solving problems and discussion. It uses a systematic approach based on modeling systems by application of basic physics principles, making assumptions, utilizing multiple representations (not just mathematical) in order to become proficient at problem solving. Lab work is required and is designed to help students develop a questioning approach to physical situations, distinguishing the significant behaviors from the less significant behaviors of a system under study.Login: guest_oclPassword: ocl
Based on knowledge of the unit Circles, students see how sinusoids (Sine and coSine waves) get their shapes.
The lectures introduce a number of topics that are important for IWRM and the modeling exercise. The lectures introduce water management issues in the Netherlands, Rhine Basin, and Volta Basin. The role-play is meant to experience some of the social processes that, together with technical knowledge, determine water management.
This virtual simulation promotes the application of knowledge and skills related to interprofessional collaboration and infection prevention and control practices. Learners will need a foundational knowledge in infection prevention and control practices, including routine practices and additional precautions guidelines. Learners will use their assessment and communication skills throughout the game. By the end of the virtual gaming simulation, learners will be able to apply interprofessional communication skills to foster collaboration and provide safe client care, demonstrate knowledge and skills related to infection prevention and control practices, and identify high risk areas to break the chain of transmission.
Introduction to seismic theory, measurements and processing of seismic data to final focussed image for geological and/or physical interpretation.This course deals with the most important aspects of reflection seismics. Theory of seismic waves, aspects of data acquisition (seismic sources, receivers and recorders), and of data processing (CMP processing, velocity analysis, stacking, migration) will be dealt with. The course will be supplemented by a practical of 6 afternoons where the students will see the most important data-processing steps via exercises (in Matlab).
Online Statistics: An Interactive Multimedia Course of Study is an introductory-level statistics book. The material is presented both as a standard textbook and as a multimedia presentation. The book features interactive demonstrations and simulations, case studies, and an analysis lab.
OpenGrade is open-source software for teachers to keep track of grades. It runs on Linux, as well as some other operating systems.
Spotter is a program that lets students check their answers to math and science questions. It handles symbolic as well as numerical answers. The software is free and open source.
The Teach the Earth Portal has hundreds of high school through higher ed geoscience educator shared content ranging from low stakes to high stakes undergraduate core level to graduate level resources. More recently, have also added virtual field experiences appropriate for core course to upper division field camp (in response to pandemic necessity for Summer 2020 Field Camp revisioning). Many of the contributions are from members or partners with the National Association for Geoscience Teachers. There is an ongoing review process by professional peers to vet content submitted / aggregated into this portal during the past several decades.
In order to promote students’ conceptual understanding and learning experience in introductory statistics, a technology task, which focuses on the probability distribution in which means are defined, was created using TinkerPlots, an exploratory data analysis and modeling software. The targeted audiences range from senior high school grade levels to college freshmen who are starting their introductory course in statistics. Students will be guided to explore and discover the movement behaviors of means of a set of numbers randomly generated from a fixed range of values characterized by a predetermined probability distribution. The cognitive, mathematical, technological and pedagogical natures of the task, as well as its association with the statistics education framework based on the Guidelines for Assessment and Instruction in Statistics Education (GAISE) by the American Statistical Association, will be elaborated. A brief discussion on what cognitive design principles this task satisfies will also be provided at the end.
The speech concepts you have examined in Units 1-8 culminate in the speech project featured in this unit. This unit contains the requirements for the informative speech. You have already seen most of this material from previous course weeks. This was to give you an early opportunity to become acquainted with it. You are now viewing the formal folder where you will read the speech requirements and submit your speech outline.
When is an extremely simple personal calendar program, aimed at the Unix geek who wants something minimalistic. It can keep track of things you need to do on particular dates.
