This practicum report describes an intervention to teach critical thinking skills in two courses in a community college early childhood education program. The objectives of the intervention were to ensure that: (1) students will become aware of critical thinking skills; (2) students will show an increase in their use of critical thinking skills in their written work; (3) students will show an increase in their use of critical thinking skills in class discussion; (4) students will use critical thinking skills as a rationale for decisions about preschool children; and (5) instructors will be aware of an increased use of critical thinking skills by their students. The intervention included a revision of classroom questioning, discussion, and quiz techniques; classroom presentations that modeled critical thinking and decision making skills; and students' journal writing and quiz writing. The objectives were measured by instructor logs, student journals, student work portfolios, student papers, and pre- and post-intervention scores on creative reasoning and critical thinking tests. Results indicated that the fifth objective was not met, and that the second objective was met by one-third of the students. The other objectives were met. A reference list of 40 items is provided. Various materials used in and pertinent to the intervention are appended. (BC)
