Electrochemistry (oxidation state? Neutralisation Reaction? Electrolytic Cell? Equilibrium? Molecular Mass? Or do you need to use a Data Sheet to look up a physical/chemical constant? This provides students time to review what has been presented, fill in the gaps, and interpret the information for others, and thus learn it themselves. Solubility Rules? Calculation of Electrode Potential (emf)? Liquid? Equilibrium? Step 3: Check that all the data you used were correct. Neutralisation? Energy Profile? reaction rate? The use of concept maps may also help students understand concepts and to relate them to one another. Calculation of pH/pOH/concentration? Gases (type of? displacement? Although teachers would like students to solve problems in whatever way they are framed they must be cognizant of the fact that these subtle changes will make a difference in students' success in solving problems. Binary Inorganic Nomenclature? Of the, a second contribution was the discovery of the chemistry problem solving classical sense. Please try again. You can check whether your solution seems reasonable in lots of ways, here are a few: If a reaction gives off energy (exothermic), the temperature of the reaction mixture should increase, if your answer shows a fall in temperature, you need to STOP and go back to the beginning of the problem solving process. Research Matters is a collection of brief, research-based issue papers developed by NARST members for the science teaching community. Oxidation State? Solid? *To give students to opportunity to be creative. complexometric? state the meaning of this and identify its essential components, give the characteristics and features of this, identify issues and give the key points for and against this, note the differences between these things, make a judgement about this based on some specified criteria, or, determine the value of this, relate cause and effect, make the relationship between things clear, give the reasons why or how this is so, look closely at the information given in order to discover something, from the information given, select the relevant and/or the approriate details, infer something about this from what is known, plan, inquire into, and draw conclusions about this, support an argument or conclusion by giving reasons, use the different pieces of information provided to make a united whole, give the main features of this, sketch this in general terms, suggest what may happen based on the information provided, put forward an example, point of view, idea, argument, suggestion etc for consideration, present remembered ideas, facts, experiences, identify from knowledge, experience or character, carefully choose something in preference to other things, pull the various pieces of data together into a whole. and read each step in your game plan carefully, making any additions as required, BEFORE you continue implementing the game plan.
