The BioTopics website gives access to interactive resource material, developed to support the learning and teaching of Biology at a variety of levels.
BioTopics interactive innovations
Text and graphics
Rollover techniques are widely used on this site, hopefully to enhance the learning experience.
Using the mouse to pass the cursor over many of the graphics will cause diagrams to become labelled. Try this on the cell diagram below.
In many units, rolling the cursor over hidden text may be revealed, so that you can > test yourself!
These techniques form the basis of on-line tutorials. With tablets or smartphones, double-tapping performs the same function as mouseover.
I am also increasingly likely to use pop-up windows that respond to passing the mouse cursor over words in the text in order to give definitions or further explanations to cover technical terms etc. This is not available on tablets and smartphones, however.
Animations are used where there is an educational benefit, such as this illustration of plasmolysis. Being in GIF format, these do not require plug-ins such as Flash to be loaded. Try clicking on the image below.
Image maps and tool tips are also sometimes used to append extra detail on demand. Leave your pointer resting on the different parts of the diagram of a glucose molecule below!
A major section of the site has involved me in the production of pages devoted to interactive 3-dimensional molecular models - usable at a number of different levels.
This section is more acceptable on tablet computers (and even phones). These JSMol files are accessible from this link.
Originally these were based on JMOL Java applets, which gives a more reliable high-quality image with smoother and faster interactivity, but this is unavailable on some computer platforms. Unfortunately, some browsers interpret this technology as a security risk, and require users to click on a warning page before proceeding. There is no intrinsic risk from using these pages on this site. These JMOL files are accessible from this link.
Another experimental feature : audio.
OK I have tried to put in sound in various formats in the past, but this was not supported by all browsers. The HTML5 format is more flexible, although different browsers have different preferences!
How do you say 'systole':
I would appreciate feedback to tell me if these (and other features) work on your system, at home or in a school/college, on a stand-alone or networked computer, or a tablet iPad or Android device - please click on the FeedBack icon on the bottom left of this page.
Watch out for these icons which bring up animations or photos when clicked.
The site is very stable and continues to be developed, although not quite at the pace I would like!
