Summary: ``An extremely simple approximate variational method for the study of the eigensolutions of the one-dimensional Schrö-\break dinger equation is introduced, based upon the idea of employing scaled eigenstates of the harmonic oscillator as generating functions for the generator coordinate method. The approach is successfully applied to a variety of situations.''
