How To Use Wiki In The Classroom
The order of representation is fixed, with the value of the \(x\) coordinate coming first, followed by the value of the \(y\) coordinate. The Cartesian product is the ordered product of two elements, such as \(x\) and \(y.\) Let us know about the Cartesian product in detail. More and more classrooms are now learning, creating, reading, and testing online. In order to keep up with our technologically demanding lifestyles, the traditional classroom is making way for such innovative tools as wiki. Not only is this an inexpensive way to manage your classroom, it’s also a fun way to engage students in content across the curriculum.

In rectangular coordinates, the Laplacian of a vector is defined as a vector whose components are the Laplacians of the corresponding components of the vector. ∇2A≡â x ∇ 2A x+ây ∇ 2A y+âz ∇ 2A z (22) Note that this definition is specific to rectangular coordinates. In other coordinate systems the Laplacian of a vector is not so.

float isometricX = cartesianX - cartesianY; float isometricY = (cartesianX + cartesianY) * 0.5f; And the reverse is. float cartesianX = (2.0f * isometricY + isometricX) * 0.5f; float cartesianY = (2.0f * isometricY - isometricX) * 0.5f; That's assuming square tiles of unit length. I'm not sure how your MAP_HEIGHT plays into this, but you should.

4.4.1 Cartesian Coordinates Because ζ = ˆk ·∇ ×V, ∂ ∂x [v −momentum eq. in Cartesian Coordinates ] minus ∂ ∂y [u− momentum eq. in Cartesian Coordinates ] gives D(ζ +f) Dt = vorticity dilution + tilting horizontal vortices + microscopic solenoid • Vorticity dilution, or.. The two coordinate systems of the element are called the pin point coordinate system 1 (PCS1) and pin point coordinate system 2 (PCS), respectively. Both coordinate systems are displayed in the 3D view by a Cartesian coordinate system. All forces and torques will be resolved in the internal element coordinate system (ECS).

Cartesian Coordinates To understand a coordinate system, you must know its relation to the Cartesian coordinate system, the representation of the position vector, the shapes of the constant coordinate surfaces, the three independent coordinate directions, and the line element represented as d or dr . For this reason, the Cartesian system is.

  1. Wikispaces.com
    Designed specifically for use in the classroom, wikispaces is a social writing platform that also acts as a classroom management tool by keeping teacher and students organized and on task. Not only does this site provide easy to use templates, it’s free and also has a variety of assessment tools. Teachers can also use wikispaces to create assignments and share resources.
  2. picoreplayer shutdownAt its most basic level, this website is free to users. Some of its features include easy to use website templates with unlimited pages, link alternatif forebet and domain name, control over ads, and the chance to earn some money with ads, which can be used for the next class trip.
  3. frappe realtimeWith over 300,000 education based workspaces, this wiki-like website offers educators a range of options that encourage student-centered learning. Students can build web sites or web pages that can be shared with other students and staff.

They are defined in the Cartesian,cylindrical, and spherical coordinate systems. A. Cartesian Coordinates From Figure 3.1, we notice that (1) Differential displacement is given by dl= dx ax + dy ay + dz az Afigure 3.1 Differential elements in the right-handed Cartesian coordinate system.

  1. Set Clear Expectations
    Before setting wiki guidelines and sharing them with your students, consult your school’s policies on social media. Provide students with written guidelines that must be adhered to. Let students know that if they publish inappropriate content, there will be consequences. Asking students to sign a contract is also an option.
  2. Start Small
    Take baby steps. Everyone will benefit from gradually increasing wiki use in the classroom. By starting small, teacher’s can stay on top of monitoring classroom wiki, thus remaining in control.
  3. Ask for Help
    Although wiki is fairly easy to use, there are times when you’ll run into stumbling blocks. Ask for help when you don’t understand something. You’d be surprised at much your students and colleagues might know about wiki.
  4. Read other Wikis
    As a class and individually, explore other classroom wikis. This will give you ideas and inspirations for your own wiki pages.
  5. Let Wiki Work for You
    Wiki is more than just a learning tool for students; it’s a communication tool for teachers. Use wiki to keep parents informed and post assignments and other class related content. Your wiki page is easily edited and updated so there’s no more need for a last minute trip to the copy machine.
  6. School-wide Wikis
    Use wikis to showcase field trips, class events and school-wide events, such as the prom or last week’s football game.
  7. Pinterest
    This site has a wealth of information on wiki for the classroom. Simply type in a search term such as "wiki tips for the classroom".  If you don’t already have a Pinterest account, learn more about it through verizon orbic no command.
  8. Collaborate
    Do lots and lots of group work. Create assignments that require students to work together, continuously communicating as part of team as they would in the real world.  For example, a media class can work in teams to create an advertisement for a product of their choice that involves print and/or video.  For a science class, have students work together as a research team investigating the sudden drop in the local wolf population.

  1. Historical Figures
    Instead of just another boring academic paper on an historical figure, make research and documentation fun by creating wiki fan pages. Students can add and edit text, post photos and famous quotes, as well as links to the references they used.
  2. Student as Editor
    Turn grammar into a challenging and competitive game. Have students use wiki to edit text with grammatical errors. Teachers can put students into groups and those with the most edits wins.  Individual edits can also be counted.
  3. Join the Debate Team
    Using a written set of guidelines, teachers post topics that students can argue by using wiki online forums. Teachers will monitor the discussions/debates while students learn online debate etiquette.
  4. Create a Collaborative Story
    Start with one sentence pulled from a hat, “The girl looked beyond the dusty field and saw a team of horses approaching, their riders hands tied behind their backs.” From here, students add and edit text to create a story. Set a minimum amount of words each student must submit. Chances are, you’ll actually have to set a maximum amount of words.
  5. Poetry Class
    For English class, the teacher can post a poem online and have the students discuss its meaning.  Students can also post their own poems for peer review.
  6. Book and Film Reviews
    Students can use wiki to write assigned book and film reviews. Other students can add to as well as comment and discuss the reviews on a monitored forum.
  7. Word Problems
    For math class, teachers can post word problems on wiki. Students work individually or in groups to solve the problems.
  8. Wiki Worlds
    For history and social studies, students can create pages for historical events such as famous battles or specific periods in history, creating entire worlds based on historical facts.
  9. Geography
    Wiki pages can be used to study geography by giving states or countries their own wiki page. Have students include useful and unique information about each geographical area.
  10. Fact Checking
    The reason why wikis is often blacklisted as a reputable source is because not everyone who contributes to a wiki page is an expert. Keep your students on their toes by assigning them to fact check each other’s work.
  11. Riddles
    Encourage teamwork by posting riddles and having groups of students solve them through online collaboration. The students will use a forum to discuss what the possible answer is.
  12. Group Assessments and Tests
    As an alternative way to administer assessments, consider using wiki group assessments.  Students work together, helping one another to achieve success.
