The website contains of animations of mechanisms for many of the fundamental reactions covered in undergraduate organic chemistry.
Type of Material:
A set of animations which can be viewed step-by-step or as a movie.
1. May be used by the instructor in the classroom to present the main types of organic reactions 2. May be used by students for individual or group study and review of the detail steps for each type of reaction
Standard conputer platform
Identify Major Learning Goals:
1. To understand the major types of organic reactions 2. To understand the individual steps involved in each of the reactions
Target Student Population:
College Organic Chemistry students
Prerequisite Knowledge or Skills:
The site would be most useful to students who have already covered the theoretical aspects of reaction mechanisms and basic organic chemistry concepts. No specialized computer skills are needed to utilize the site.
Evaluation and Observation
The site has animations of a range of organic mechanisms covered in undergraduate organic chemistry. The animations are well-designed and depict individual steps in each reaction, that can be manipulated to go back and forward to understand the processes.
Some are the arrows are not in the correct positions and may be ambiguous or even misleading to students who are not conversant with the material
Potential Effectiveness as a Teaching Tool
1. These animations have clarity and details that will facilitate learning 2. They can engage the learner and provide information in an interactive format 3. The animations can be run in a sequence, or they can be stepped through one frame at a time forward or backwards for better understanding 4. The range of reactions covered in this site is good. In addition, the mechanisms are for the most part clearly accurate.
Similar material is available in textbooks and in their companion websites. It is not interactive. The site would be useful to instructors wanting to illustrate their lectures. However, there is no companion information to depscribe the process making it difficult for students to decipher mechanism(s) that they are having difficulties with. The site would benefit from interactive exercises and from an outline of the reaction (reactant, reagent and product) before the mechanism is presented.
Ease of Use for Both Students and Faculty
1. Material has been presented in a very clear, systematic format. 2. Each reaction can be accessed from the main menu, with easy navigation and no distracting design elements. 3. The design allows user to re-play, stop, start each animation as needed without trapping the user or causing problems. 4. The software is robust and the site is in working order.
It would benefit from having some introductory narrative to give the user an idea of how to use the features within the animations: such as step-by-step or letting the animation run through its sequence. The browser back button is used to return to the main menu.
Other Issues and Comments:
This is an good set of animations of organic chemistry reactions that can be used in variety of learning environments
