Spiritual formation is both an opportunity and a challenge for educators in Christian colleges and seminaries. How can students be nurtured and guided in developing spiritually within the curriculum? Drawing on a number of educators, studies, and arguments, this article develops a rationale for engaging in spiritual formation and for the use of practical assignments or “soul projects.” A selection of such projects is grouped into genres, followed by a brief exploration of best practices and an evaluation of such assignments.

A three-dimensional photoelastic study was made to determine the stress state around the wall and bottom of a well bore due to fluid pressure with~n the wellbore and unequal principal geostatzc stresses.Models simulating the well bore were made from a phthalic anhydride-cured epoxy resin. The froz~n stress technique of three-dimensional photoelastzcity was used to determine the stresses within the model. Two separate problems were solved:(1) hydrostatic pressure on all sides of the model with the exception of the inside of the hole, and (2) uniaxial compression perpendicular to the center line of the hole.The results are presented in the form of contour curves for each stress component. The curves cover a region which extends several hole radii from the bottom and wall of the hole. By proper use of these results, the state of stress may be calculated for any point on the wall or bottom of ~he hole, as well as for any point within the materzal that surrounds the hole. A systematic method is given for calculating these stress components for any combination of fluid pressure within the wellbore and system of unequal principal geost~tic stresse~, provided one of the principal geostatzc stresses zs parallel with the well bore.The results show that stresses around the wall and bottom of a wellbore, induced by an unequal system of principal geostatic stresses, are appr~ ciably different from those induced by geostatzc stresses that are hydrostatic. For unequal principal geostatic stresses, the experimentally determined stresses on the wall of the hole several radii from the bottom are in good agreement with the stresses calculated by elastic theory.
