Abstract

 

Two significant additions to our Contemporary Chemistry Project have been: (1) the introduction of a series of essay and multiple choice questions for each animation, which allow in-depth comprehension testing of each animation; (2) a new custom tool for classroom and browser presentation of animations that allows the instructor complete freedom in choosing the order of animations and questions from a searchable database. It also gives the instructor the option of modifying these questions and creating new essay and multiple choice questions.

 

Introduction

 

            In our previous Newsletter article (ÒContemporary Chemistry: Visions of An Integrated Text/Multimedia Module ApproachÓ), we described the development of a unique, interactive multimedia project that utilized Flash animations integrated with an introductory text.  The project is designed for non-science students and introduces chemical principles on a need-to-know basis.

 

We have now extended the above project to include a new concept in student feedback, a combined essay and multiple choice question sequence for each animation. This sequence significantly expands the teaching possibilities and depth of coverage within the project. It also allows a gradual buildup of the levels of sophistication. We also describe a new tool that gives the instructor complete freedom to select animations and essay questions for classroom or web use from a searchable database.

 

New series of essay and multiple-choice questions

 

We have introduced new essay questions with mouse rollover hints and complete, sometimes extensive answers that allow in-depth challenges to the student observing and interacting with the animations. A popup screen allows the student to input extensive answers to essay questions in writing and allows comparison with the correct answers. An option is to have studentÕs typed answers forwarded to the instructor for reading and grading before the correct answer can be revealed.

 

Multiple-choice questions that follow the essay questions allow a test of whether the student has comprehended the sometimes extensive, in-depth answers to the essay questions.

 

Thus the series of essay and multiple-choice questions allow in-depth exploration of the studentÕs understanding of theoretical underpinnings inherent in that animation. The series of questions also allow the introduction of additional related topics and an exploration of higher levels of sophistication regarding the subject of the animation.

 

New tool for custom classroom and browser presentation of

animations, questions,  and notes.

 

The Contemporary Chemistry project already had a tool for selecting and displaying individual project animations from a menu (http://contemporarychemistry.com/

Our just-completed Slideshow Creation Tool allows the instructor to create a custom presentation from a database of animations and accompanying series of essay and multiple-choice questions prepared for each animation. Illustrations taken from the text chapters can also be included in this database, which is searchable by chapter and by key words. Presentation of the product slideshow can be made in the classroom or it can be delivered through the Internet to groups of students or to individual student computers for tests, homework assignments, and post-session review of classroom presentations.

 

Complete flexibility is provided to instructors through their ability to select the animations and their order from the databank.  During every stage of preparation, each animation may be viewed and engaged, and the order of presentation of animations can be easily rearranged. With each animation, there is available a series of essay and multiple-choice questions whose content can be edited by the instructor. Alternatively, instructors may prepare their own essay and multiple-choice questions with a flexible number of possible answers. An additional text panel can be added to each animation that can contain notes for the student or instructor, pop quizzes, or instructions.
