      The listener follows along and catches any errors that occur. The role of the listener is to ask for clarification but not to guide or correct the problem solver. Think alouds work best when the task or problem evokes elaborate thinking. A question or task that has a simple or single answer is not a good choice for a think aloud.

      Expect the solver to know formulae for the surface area of a sphere, circumference of a circle, etc. In the above illustration, the solver could assume that the Earth is a cube and still arrive at the correct answer. The calculations show the need for the solver to be familiar with exponential notation.

      In this question, you must recognize that perchlorate, ClO4-, and hydroxide, OH-, are polyatomic ions and will not break apart. Also, this is an acid-base reaction, so the products should be salt and water. 4. Decomposition: ZnCO3 + heat ( ZnO + CO2. When reactions have heat as a reactant, it is very likely that they will involve decompositions.
