     3Bolt offers two web-based analytic tools, ''course maps'' and ''lesson comparer''.
     4You can use these tools to iteratively refine your course:
     5
     6 1. Develop an initial course
     7 1. Operate the course until a statistically significant sample size of interactions exists
     8 1. Use the course map tool to find problem spots
     9 1. Develop alternative lessons
     10 1. Operate the course some more
     11 1. Use the lesson comparer to find better lessons or to do demographic adaptation
     12 1. go to 1.

     14=== Course maps ===
     15
     16A ''course map'' shows you the overall flow of students through your course
     17(in the style of Charles Minard's map of Napoleon's march to Moscow in the war of 1812),
     18revealing the points where they are getting bored or discouraged.

     21
     22A course map shows you graphically how many students enter each step of the course,
     23how many seconds they spend there,
     24and their average performance on exercises.
     25You can get a color-coded breakdown by any student attribute,
     26and you can select a subpopulation based on attributes.
     27
     28=== Lesson comparer ===
     29
     30You can develop several alternative lessons for the same concept and,
     31using the "set" construct, arrange for them to be selected randomly,
     32followed by a single exercise.
     33You can then use Bolt's ''lesson comparer'' tool to study the results.
     34The tool will tell you, for a given statistical confidence level:
     35 * whether one lesson is worse than another, e.g. students viewing lesson A score worse than students viewing lesson B
     36 * whether a given lesson is better for a particular demographic subgroup, e.g. a lesson is highly effective for females under 18.
