Parts of the Face
These pages contain programs in HTML and javascript to consolidate skills in Science - Chemistry(up to GCSE), Physics(GCSE, A-level & medical), Biology(up to GCSE) electronics (up to A-level) and maths and now languages - well Italian. They include testing vocabulary by spelling and / or listening as well as calculations and writing and balancing chemical equations. They use 'Drag and Drop' (DnD) techniques, show/hide sections, and DOM.
Any ideas/suggestions, please email
me. The list of areas covered is in above menu (mouseover to expand the lists).
These are mainly drill exercises. They do not profess to teach the principles - these are taught in the classroom and on websites such as mathisfun.
Programs were initially written for MSIE6. They were updated for MSIE7. They may work with IE11 / Chrome / Firefox but best to check. To check compatibility with some other old browsers: click
here.
I have added some drag and drop and other Italian exercises.
The site is for learners/students and teachers alike.

Pop-ups
Many programs have 'help' pop-ups. To benefit, you need to allow pop-ups. They may show the equation given in the specification or give some other help.
There are no ads on the calculation pages. So no ads should popup, or, popunder.
The pop-ups close as soon as they lose focus. Two reasons: to encourage you, the student, to keep the idea in your head and, also, new pages would appear in these small windows.
Browsers
Programs are initially written for MSIE6/7 set to 'Medium' Text-Size. To check compatibility with other browsers: click here. Programs using DnD are most difficult to get compatible with other browsers, including IE7. If you want to use a particular program and are finding difficulties with your browser, please let me know and I will try to help. I don't have access to Mac or Apple computers so am unable to check compatibility.
Cookies
Many programs use cookies to retain your scores. To benefit, you need to allow cookies.

Disclaimer
Before IE7, I wrote the programs for IE6.
Most were then tested in other browsers. Since May, however, all programs are written for IE7. In addition, programs are occasionally updated in IE7 to take advantage of improved techniques. I have not yet been able to check all the older programs for compatibility with IE7. Also, I have not always had time to check changes in other browsers.
Teachers Please check any program before using it with a class especially if you are using another browser as programs are subject to alterations in script which may affect working in other browsers. Programs using DnD are particularly at risk here!

All programs use javascript. To use the programs at all, javascript must be enabled.
Screen Resolution:
Best viewed at as high a resolution as possible. Minimum 1024 x 768 advised. 800 x 600 is usually inadequate.
Full screen (press <F11>) is useful. (press <F11> to exit).
Additions & Updates - 2020
November: added a menu to pont to some of the Italian vocab programs I've written
January 2017: Thanks to Neil Wallis for the analog clock and HelpWithMaths for the digital version I was able to write a program to display random times at the press of a button and, on the press of another button, tell you the time in spoken and written Italian. As there are different ways of saying the same time (7:50, ten to eight, almost eight, ten minutes to eight, ten to eight in the morning, 7.50am...I've opted to allow yourself time to think of the time, say it to yourself/out loud, then check how you did.
December 20: Found javascript function by George Claghorn on stackoverflow.com to enter accented characters into the textbox at the cursor by clicking on a link on the page. Much easier for us poor inglesi. Updating a few programs with this.
December 17: Updated the Directions program to allow user choice of level of difficulty.
December 16: Added a text to speech button <input onclick="var msg = new SpeechSynthesisUtterance();msg.text = 'word to speak';msg.lang = 'it-IT';window.speechSynthesis.speak(msg);" type="button" value="Play" /> using SpeechSynthesisUtterance() which worked fine with my Chrome and Firefox but not IE. However, it spoke in US English on my wife's computer! I found it only works on the very lates Chrome and not in IE at all. I found another possible free speech to text at responsivevoice.org and using their Voice API I was able to get snippets to play with a reasonable Italian voice in IE as well as Firefox and Chrome.
December 15: Tried the Directions program with a person with 10 lessons and a couple of visits to Italy under their belt. She found the simple items ok but froze at the longer items, which came up randomly. So, I decided to modify the program to allow some user choice.
December 13: Alex's new coding makes it very easy to alter the labels. So, did a quick face parts in English and tried it out on a one-to-one basis with 4 - 10 year olds.
December 12: Alex, my son, recoded my drag and drop programs to work on iPads. They need to be at least 728 x 1024 in size.
December 12 / 2016: minor(!) corrections to vocab to Food and singular/plural programs.
December 2016: Nothing beats going to Italian classes (maybe going to Italy!) but there is so much to learn. Knowledge of vocab is, I am finding, very useful. So, I am adding lots of lists of words to test translation knowledge. I like lists! You can testyourself on the iPad at colazione. Gradually making some of them them printable. Included are: conjugation of the present tense of different types of verbs, The correct use of the definite article to agree with the word it precedes. Lists of nouns in different themes. Numbers. Etc. These lists help me learn and help me revisit my programming skills - sadly very rusty. If they help you, please email me and let me know. Also any other ideas would be useful.
December 2016: I'm starting to lean Italian so have added some drag and drop exercises for learners of Italian - at a basic level!
Also I've added some exercises on the present tense as well as numbers and some vocabulary
February 2016: starting checking compatibility with IE10 & 11, MS Edge, Firefox and Chrome. I'm finding the chemical equations (drag and drop) are good in IE and Firefox, don't work at all in Chrome
and satisfactory in Edge. So, IE and Firefox are recommended. Also started amending dropdown labels for number of moles so 'blank' = 1 mole to be consisten with handwriting equations.
January 2014: Improving coding and layout of Maths/fractions programs to give feedback on screen rather than by popup alerts.
Adverts: I don't run ads on any of the testyourself pages (except this home page). Please feel free to donate say the cost of a pint of beer (about £3.25 in the Midlands) using the PayPal link opposite to help the site keep going.
History of additions / alterations:
6 July 2013: tweaks to the coding of some maths programs e.g. percentages to get them running and / or improve layout in current IE and Mozilla browsers. Too many to check so if there's one you would like to use but doesn't work / needs improving, please email me.
5 January 2010: Engineering Notation and Percentages recoded to allow scores to be recorded on Server. Thus, exercises set for homework are marked and teachers can retrieve the marks to check homework attempted. Please email for details. This service is free to teachers emailing from a school email address.
16 November: Percentages eliminating most of the popups and tick / X images to mark your answer.
9 November 2009: BIDMAS calculations (Maths), Engineering Notation examples (Electronics)
5 November 2009: Percentages (Maths)
30
October 2009: Sums with fractions(Add, subtract, multiply and divide) - see Maths Menu above. Script only allows numerical input.
Apr 27 2008: Setting up a Departmental domain? Want to use Server 2003?
I have written a script to upload students from an Excel Spreadsheet into Active Directory. All you need to enter in Excel are: First and Second Names, Year of entry to school and Departmental Teaching Group. It provides a unique logon name (format <entry year><surname><unique id if necessary>), and an initial, randomised password which can be displayed by projector.
It organises by Year Group.
It reads the Teaching Group and enters students into these groups in AD and also sets up a home folder for each student.
You can edit the spreadsheet at any time and rerun the script. It will resort the students in AD and their home folders into any new teaching groups so you don't lose any of their work. Ideal for the new school year. Email me
for more details - the script and sample SpreadSheet are free.
Jan 20: Worked out how to allow only decimal number entry to input text boxes ie: numerals 0-9 and only one decimal point and forcing a leading 0 if < 1. The coding allows for deletions of any of the digits and / or '.'. Starting to edit programs starting with 'density'.
Jan 6 2008: Calculators for 3 variable calculations -
Density
Speed
.
Useful for Y6 - Y9 when students seem randomly to use calculators to calculate e.g. density as mass/volume and volume/mass! Of course, students can put all the information into a class spreadsheet. However, I have found these calculators useful as aids to confirm their own calculations. Answers are shown to 3 sig figs.
For the IE7 version, all keys except 0-9 & '.' are disabled. Non-numbers are also captured.
If you would like any similar calculator produced, please let me know and I will add it to this site.
