Let slideshow = new ChemDoodle.SlideshowCanvas('slideshow', 250,250) Examplesįour molecules are loaded into the slideshow, which is given a creative marker-drawn style: When everything is ready, the AnimatorCanvas.startAnimation() function will start the slideshow while the AnimatorCanvas.stopAnimation() function will stop it. The transition is 1 second by itself, so for best results, choose a timeout of at least 2 seconds. The default is 5000ms, which will swap molecules every 5 seconds. So, the animation speed (time between transitions) can also be set by specifying the AnimatorCanvas.timeout variable in milliseconds. As with the RotatorCanvas, the SlideshowCanvas is a child of the AnimatorCanvas class, which in turn, is a child of the Canvas class. The order that you add the frames is retained during the animation. The addFrame() function takes two parameters, the first an Array of Molecule data structures, and the second an Array of 2D Shape data structures. new ChemDoodle.SlideshowCanvas(name, width, height) Īfter initialization, you add frames to the slideshow with the SlideshowCanvas.addFrame() function. The SlideshowCanvas constructor takes the same parameters as the ViewerCanvas constructor. Note: Quizzes.next currently presents a number of technological issues with our proctoring tools, and instructors have expressed that using a multiple choice question where students would simply recognize the correct drawing from a list is unacceptable for their learning outcomes.While very complex programmatically, the SlideshowCanvas component simply displays multiple molecules, one at a time, with transitions in between. It would be a very helpful function to allow instructors to annotate drawing corrections directly on the student's entry when grading. This would be vastly improved and streamlined if instructors could simply create a 'drawing' type question directly in Canvas where students would use a mouse or other device to input lines and text that would then be manually graded by the instructor.

The current workaround is that students download a PDF as a question type within a proctored exam and submit this later as an assignment submission, but there are many technological and time-consuming issues with this process for both students and instructors, including confusion about the numerous steps, printing issues, scanning issues, uploading, file type errors, verifying that students completed the drawing within the time allotted, and others. Many of our fully-online courses (particularly in science and math) require that students draw a diagram or process in their assessments, and when combined with proctoring tools, this becomes a complicated process.
