Thank you. / THE PROBLEM: When two modes of teaching of the natural sciences (problem-solving and information-giving) are used both on television and in the classroom, will there be differences in the amount and quality of learning?
POPULATION: 36 fifth grade classrooms, randomly selected from cities and towns within 50 miles of the city of Boston, Massachusetts.
PROCEDURE: 36 teachers took part in the study. 12 of these were trained in the use of problem-solving methods with the teaching of natural science; 12 were trained in the use of information-giving methods with the teaching of science; and 12 were given no specific training and functioned as a control group.
Two television series containing 20 one-half hour programs on the natural sciences were televised by WGBH-TV, Educational Television in Boston, Massachusetts. Ten programs were identical for both series. The other ten programs covered the same content areas, but were different in organizational make-up. Ten series "R" programs stressed the giving of information, ready-made concepts, and generalizations. Ten series "E" programs stressed the postulation o.f problems, time lapses for student response and posing of solutions.
Classroom teachers in the two experimental classroom groups were provided with manuals correlated with the two experimental television series of ten programs. Although basic concepts to be covered were identical, one manual stressed the learning of information, the other the solution of problems.
Four tests were administered during the experiment: The Otis Self Administering Intelligence Test (Beta Form) to establish distribution of intelligence; a Science Information Test to evaluate the learning of facts; a Science Concept Test to evaluate ability to solve problems; and a Science Reasoning Test to assess ability to reason logically. All tests were administered prior to the initiation of the television series in October 1961. All except the Otis were administered again immediately at the conclusion of the television series in April 1962.
The Minnesota Teacher Attitude Inventory was administered in October 1961 to participating teachers as an aid in validation of teacher selection. The experimental design consisted of three groups of 6 classes viewing each television series, and two groups of 6 classes experiencing each of three classroom treatments.
RESULTS: There were no statistically significant differences by either television treatment or classroom treatment. There were, however, differences in measured IQ between boys in different groups. Reliabilities of the tests used ranged between .85 and .92. Two significant results should be mentioned: 1) Note-taking in class, although not initially considered as a variable was a significant factor in experimental outcome; and 2) the basic assumptions for the use of difference scores as raw data for analysis of variance proved untenable with data collected for the study and corrections in difference scores for both ceiling and floor effects needed to be made. These corrections of gain scores changed some previously significant results to non-significant results. Approximately 75 per cent of the predictions of the direction of difference of group means by hypothesis were accurate.
CONCLUSIONS: In an experiment of this sort, many variables which prejudice outcomes are not fUlly understood. Difference scores as raw data for statistical analyses are subject to distortion. It would seem that inductive problem-solving, is at the least, as effective as information-giving in the learning of natural science by fifth graders. / 2031-01-01

The effects of cultural video resources on teaching and learning Korean languageRoh, Jaemin January 2011 (has links)
Thesis (Ed.D.)--Boston University / PLEASE NOTE: Boston University Libraries did not receive an Authorization To Manage form for this thesis or dissertation. It is therefore not openly accessible, though it may be available by request. If you are the author or principal advisor of this work and would like to request open access for it, please contact us at open-help@bu.edu. Thank you. / This dissertation sought to evaluate the potential of a customized, videobased instructional method, the Cultural Video Project (CVP), which was designed to meet the needs of both heritage and non-heritage students learning Korean as a second language in a university setting. The goal of this study was to design and create the CVP, document the implementation of the CVP, and then to assess the effects the CVP had on the area that speakers of English tend to have difficulty with, such as acquisition of honorific systems in Korean. The CVP was a series of short authentic Korean video clips and matching worksheets that the researcher created. The videos were adapted from contemporary Korean broadcasting programs and Korean films. The CVP videos were used during the face-to-face setting classroom meeting sessions as a lesson and after the classroom lesson was over, the videos were available on the school's Internet courseware for students to use for their individual practice and review. Each of the CVP video segments displayed linguistic structures, vocabulary, idiomatic expressions and cultural conventions that were partly addressed in the course's Elementary Korean course materials. The participating professor, Professor Q, helped in selecting the video segments and co-authored the matching worksheets in corporation with the researcher throughout the preparation and implementation period. During the interviews, Professor Q reported changes in her teaching philosophy while creating and implementing the CVP method in her teaching. She reported that the video technology combined with the university's courseware uses created positive impacts on her students' Korean learning experiences such as heightened interest and intense attention that helped to make dynamic and interactive lessons during the classroom meetings. Students reported their responses to the CVP in various forms: Interviews, written self-reports, in-class observation reports, results of the exams and two-forms of standard school course evaluations. The findings reveal that through the CVP practice, students increased their cultural understanding, improved the listening skills, and improved their understanding of language use in a variety of culturally specific social situations. / 2031-01-01
