We've turned a corner with Learn Chemistry. See if you can spot the difference between the site as of Sunday and the site as of today.

It took Google years to remove 'beta' from their email service. It's taken us four months (see our logo at the top of the page). But we're not bragging, there's a lot more to do to make Learn Chemistry your home for chemistry education, and yesterday's update wasn't simply a cosmetic one:

• We've made filtering resources and narrowing down your searches more powerful. When you browse or search Learn Chemistry you can use the panel at left to filter the resources under a variety of headings. With our latest update you can zoom into the subject or context of the resource. Look out for the 'Refine Search' buttons.  

Click these to bring up a menu (see right).



Use the '+' and '-' icons to expand or contract any list. Click the check boxes to select a context or subject.

The number of resources available is shown in brackets alongside each heading. When you click a check box the search will re-load with a new list of resources.

The age, audience, context, and subject filters that you've selected are shown at the top of the page. Click the 'x' buttons to remove a filter and re-load the search.



As a certain meerkat might say: 'simples!'.

• We've also added a feedback form. The form will very soon start to show up when you visit a Learn Chemistry page for the first time. We plan to start systematically collecting feedback from our users to inform future developments.
• We've standardised our icons to indicate resources for teaching or learning.
• Following feedback from our users, we've shortened the 'also of interest' and 'related resources' links in each resource page.
• We've fixed a bug with some of our flash resource links.

Let us know, as ever, what you think of the changes either in the comments below, or via the official Learn Chemistry mailbox: learn-chemistry@rsc.org.
