S.T.E.M. learning resources can help a child learn the S.T.E.M. courses, but more importantly such resources can instill an interest. Once a child develops an interest in a subject the difficulty of tutoring the child will be greatly reduced, whether the child is being homeschooled or just struggling in a traditional school. If enough interest is instilled the child might just seek out skills beyond school.
To get started we should know exactly what S.T.E.M. stands for. The letters stand for science, technology, engineering, and mathematics. Of these, mathematics is the key. Without a sound mathematics background, the other S.T.E.M. disciplines cannot be mastered. It is also the subject that is the most abstract.
