This study examines how preservice educators utilized Internet resources in an integrated thematic unit at the elementary school level. A cohort of 64 senior-level preservice elementary education students were required to use Internet resources to create lesson plans and teach integrated units during the semester. Three surveys were carried out to collect data regarding Internet access, computer technology background, and difficulties encountered in using Internet resources in curriculum planning and implementation. Lesson plans from the unit were analyzed to determine the level(s) of Internet usage. The examination of the thematic units revealed limited use of Internet resources with few integrating resources into the lesson plans. A Phase Two study in the second semester showed changes from the first year's findings: more inclusion of resource materials in the lesson plans with greater integration of materials and less difficulty in accessing information.
