The DALSTRA (DALis/STRAsser) Inquiry Teaching Strategy is a model of teacher behaviors regarding teaching as a process composed of three categories of actions: basic behaviors, goal-directed behaviors, and diagnostic behaviors. The materials in this document were designed for use in an inservice education program in DALSTRA inquiry methods, and they discuss: (1) skills necessary for generating original data and working with primary and secondary data; (2) structural components of an inquiry lesson; (3) a taxonomy of teaching behaviors useful in facilitating the goals of inquiry; (4) student behaviors from which teachers develop inquiry teaching strategies; (5) the process of introducing students to the entire range of decision making in inquiry (data selection/evaluation, theory appraisal/hypothesis formation/evaluation, etc.); (6) teaching behaviors for helping students in the building of problem-directed data collections; (7) a case study of data generation, collation, and arrangement that illustrates a classroom exercise in historical inquiry; (8) inquiry skills in communication; (9) the purposes, processes, and products of historical inquiry and their application to the classroom setting; (10) the rationale for building inquiry into daily classroom activity; (11) the "process dialog" component of inquiry--the discussion of what, how, and why, as opposed to the actual doing of inquiry work; (12) developing students' repertoires of learning strategies; and (13) actions that teachers may take to draw from students further information concerning their inquiry processes and abilities.
