The key feature of the resources is that students work in groups to discuss the possible solutions critically before presenting their ideas to the class.
This problem-solving activity, from the Royal Society of Chemistry, is based on the reaction of metals with acids.
This tutorial is much longer than we'd like, but this is because we are going to concentrate on some areas of concern raised by examiners (exam markers) in their reports on external exams.
Problem Solving In Chemistry
So, before you begin, you might like to go to the bathroom, get something to drink and/or eat, and get an extra cushion for your chair .... This also means checking any assumptions that you may have made. Before you laugh, I must tell you that one of the many complaints markers have about student exam papers is that the students have NOT answered the question that was asked ... Check that you have the appropriate number of significant figures, for example, if you have been given p H = 1.32, the concentration of hydrogen ions is NOT going to be 0.047863! There are some spelling mistakes examiners probably won't care about, for example there/their/they're, where/wear etc But some spelling mistakes are guaranteed to lose you marks, for example, alkane/alkene/alkyne (huge difference in reactivity for one thing! Step 5: Check that the scientific principles you applied are valid for this problem. Footnotes: (1) This approach is based on Polya's approach to problem solving in maths, which I always think of as a 'Weapon of Maths Deconstruction', but is a good general approach to problem solving. State your solution to the problem by writing it down. If, however, there is some doubt about the value, or quality, of your response after going through the checks above, you should STOP here and start the problem solving process again, from the beginning, with step 1.These resources were designed to * To improve students' ability to communicate and work together. The problem-based activities all have a variety of possible solutions. *To show students that science is more than 'getting the right answer' and that it can involve using one's own judgement.For example, the site cannot determine your email name unless you choose to type it.Allowing a website to create a cookie does not give that or any other site access to the rest of your computer, and only the site that created the cookie can read it.You will find a 1 page template (pdf) to use for problem solving here.
