The purpose of this study was to test the relative effectiveness of a linear and a context program in teaching some selected Persian words to English speaking people. A survey of the literature did not reveal studies closely related to the present study, but it revealed studies verifying the usefulness of programed instruction in general, and also some limited attempts made to set up programs for teaching Persian to Americans o There has been increasing attention by educators to programed instruction in the last fifteen years. The idea was also supported that there is a need in the United States for the study of some foreign languages, including Persian. Sixty subjects of both sexes were assigned randomly to either the linear or the context program. The programs included the same words, and they appeared in the same order in each program. The level of performance of students on three posttests given to them was the criteria for judgment of achievement. The amount of time each group spent on the program was the criteria for time comparison. The principal finding was that there was a significant difference in favor of the context program at the P < .05 level in terms of time spent. Females in the linear program received significantly higher mean scores on list meaning and overall posttest scores at P < .05 level.

<p>Tema istraživanja je proučavanje dijagrama kao alata i njegove epistemolo&scaron;ke uloge u procesu arhitektonskog projektovanja. U savremenoj se arhitektonskoj teoriji i praksi, kao jedan od najzastupljenijih alata u procesu projektovanja, koristi dijagram. Dijagramom je kao analitičkim i stvaralačkim alatom poslednjih dvadesetak godina dat značajan doprinos razvoju istraživačkog projektovanja. Iz tog razloga, ovaj rad predstavlja prilog metodologiji projektovanja dijagramima kao obliku istraživanja kojim se dolazi do novih saznanja u kreativnom činu.</p> / <p>The main topic of the research is the analysis of a diagram as a tool, and its epistemological role in the process of architectural design. In contemporary architectural theory and practice diagram is one of the most frequently used tools in a design process. As an analytical and designing tool, diagram has significantly contributed to the development of exploratory design in the past twenty years. For this reason, this paper is a contribution to the methodology of a diagram-based design as a form of a research that leads to new findings in an act of creation.</p>
