The present invention specifies a method and system for assessing breathing effectiveness via dynamic assessment of respiratory sinus arrhythmia and the consequent arterial pressure wave using the oscillometric measurement technique. Arterial pressure wave peak pressure, valley pressure, amplitude, and rate are characterized and displayed for diagnostic and remedial purposes. The dynamic change in respiratory sinus arrhythmia and resultant arterial pressure wave is visually presented in real time as user biofeedback. A respiratory sinus arrhythmia generator generates varying frequencies to which the user synchronizes their breathing cycle for purposes of increasing arterial pressure wave amplitude with a consequent increase in breathing depth and decrease in breathing frequency. An instructive method in the application of the present invention is also specified.

Embodiments can provide dynamic assessment by an expert system software (ESS) module. The ESS module may determine a minimum set of diagnostic questions to identify a student's strengths and / or weaknesses for a given subject matter. Each diagnostic question may be a unique question variant generated from a dynamic question template. The ESS module may automatically and dynamically build a personal lesson plan that includes lessons on topics of the subject matter that the student has not mastered. The ESS module may dynamically modify the personal lesson plan to change a lesson and / or add lesson(s) considered by the ESS module as necessary for the student to master the subject matter. Given the ESS module's knowledge on various components of a question such as equation(s) used to produce a correct answer to the question, the ESS module may generate image(s), customized hint(s), customized explanation(s), and / or examine student solutions in step-by-step fashion.
