The teaching resource matching system according to claim 4, wherein the data analyzing unit determines whether to readjust the teaching resource matching scheme of the subject based on a comparison result of the scheme period adjustment parameter Gb and a preset scheme period comparison parameter,
wherein the data analysis unit is provided with a first preset scheme period comparison parameter Gb1, a second preset scheme period comparison parameter Gb2 and a third knowledge point density adjustment coefficient Kv3, kv3 is more than 1 and less than 1.3,
if Gb is smaller than Gb1, the data analysis unit determines that the knowledge point density of the subject is readjusted by adopting Kv 2;
if Gb1 is less than or equal to Gb2, the data analysis unit determines that Kv3 is adopted to readjust the knowledge point density of the subject;
if Gb2 is less than or equal to Gb, the data analysis unit determines to readjust the learning duration of the subject;
if the data analysis unit determines that the x-th knowledge point density adjustment coefficient Kvx is used for readjusting the knowledge point density of the subject, the data processing unit marks the readjusted knowledge point density of the subject as V3, and sets v3=ve× Kvx, e=1, 2, and x=2, 3.
6. The teaching resource matching system according to claim 5, wherein when determining to readjust the learning duration of the subject, the data analysis unit calculates a second duration ratio Δtb of the second average learning duration Tb to the third average learning duration Tc, Δtb=tb/T0, determines to readjust the learning duration of the subject based on a comparison result of the second duration ratio Δtb to a preset duration ratio,
wherein the data analysis unit is provided with a fourth learning duration adjustment coefficient Kt4, deltaT 1 < DeltaT2, kt4 < 1.3,
if DeltaTb < DeltaT1, the data processing unit determines to use Kt2 to readjust the learning duration of the subject;
if DeltaT1 is less than or equal to DeltaTb < DeltaT2, the data processing unit determines to readjust the learning duration of the subject by using Kt 3;
if delta T2 is less than or equal to delta Tb, the data processing unit determines to readjust the learning duration of the subject by adopting Kt 4;
if the data processing unit determines that the y-th learning duration adjustment coefficient Kty is adopted to readjust the learning duration of the subject, the readjusted learning duration of the subject is denoted as T3, and t3=tu× Kty, y=2, 3,4, u=1, 2 are set.
