+== Analytics ==
+
+Bolt offers two web-based analytic tools, ''course maps'' and ''lesson comparer''.
+You can use these tools to iteratively refine your course:
+
+ 1. Develop an initial course
+ 1. Operate the course until a statistically significant sample size of interactions exists
+ 1. Use the course map tool to find problem spots
+ 1. Develop alternative lessons
+ 1. Operate the course some more
+ 1. Use the lesson comparer to find better lessons or to do demographic adaptation
+ 1. go to 1.
+
+=== Course maps ===
+
+A ''course map'' shows you the overall flow of students through your course
+(in the style of Charles Minard's map of Napoleon's march to Moscow in the war of 1812),
+revealing the points where they are getting bored or discouraged.

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