8. Identifying World Views Projected by Science Teaching Materials: A Case Study Using Pepper's WORLD HYPOTHESES to Analyze a Biology Textbook.
- Author
-
Kilbourn, Brent
- Abstract
The purpose of this study is to develop and demonstrate the use of a conceptual framework for assessing the potential of "world view" as a concept for understanding important issues in science education. The framework is based on Stephen C. Pepper's treatment of six world hypotheses (animism, mysticism, formism, mechansim, contextualism, and organicism) in his book WORLD HYPOTHESES. The study has three major parts. The first is the development of the framework (analytical scheme). The second is its use as a perspective for understanding the relationship between world view and social issues, with special reference to the relevance of this relationship to curriculum concerns. The third is a case-study, demonstrative analysis of a biology textbook, which shows how the analytical scheme can be used to detect the projection of world views to students in science teaching materials.

Biological Sciences Curriculum Study, Boulder, CO. and Steele, Joe M.
- Abstract
Presented is the second in a series of formative evaluation reports which summarizes student abilities and performance in field tests of Me and My Environment, a 3-year life science curriculum for 13- to 16-year-old educable mentally handicapped (EMH) adolescents. Discussed are the purpose and interpretation of student data for judging a curriculum. Described in relation to development of test items for the first field test year are aspects such as item format analysis. Functional abilities of students are considered in relation to intelligence and achievement tests, teacher rating of students, problem solving, cognitive development, grouping, and prerequisite knowledge. Explained are differences in performance seen in results of regression analysis and differences in performance among classes. Student performance is analyzed for the directionality and map reading, measurement and scale, temperature, and environmental subtests in Unit I; and for the energy, food chains and webs, food energy, weight and temperature, graphing, and categorizing subtests in unit II. Results are given which show that performance on 25 items in Unit I was not as high as expected, that students in one fourth of the classes showed marked gains on posttests, that one third of students in nine classes were successful on at least one subtest, and that performance on 19 items in Unit II was moderate (one third of students in six classes performed successfully on at least one subtest). Considerable revision of both units is foreseen. Also, findings are given to indicate that individual intelligence tests explain little of the variance in student performance, whereas problem solving and teacher rating do explain the variance. (MC)

Biological Sciences Curriculum Study, Boulder, CO. and Steele, Joe M.
- Abstract
The first in a series of evaluation reports gives characteristics of sites and approximately 500 students in field tests of Me and My Environment, a 3-year life science curriculum for 13- to 16-year-old educable mentally handicapped (EMH) adolescents. Described are the field test design, which involves 14 data gathering approaches, and the timetable (1971 through 1975) for development, revision, and commercial publication of the six units. The purposes of the initial field trials are given to be (1) testing to ascertain student success on each activity, (2) observing implementation problems and/or teacher approaches that enhance program effectiveness, (3) obtaining data on students' abilities and progress, and (4) serving as a laboratory for later curriculum development. Major questions examined are whether students can perform the cognitive tasks, how the activities work, how materials are used by teachers and students, and what student changes occur in areas such as task attention. Discussed are the selection of 10 state sites and criteria for selection of 14 teachers for field test 1 (near end of year 2); and selection of 21 teachers for 14 state sites for field test 2. Given for field test 1 are student characteristics: three of every five students is male; 75% of the sample is in the 12- to 14-year-old range; and one third of the sample consists of black or chicano students. There were more students in all age ranges and more representative minorities in field test 2. Major findings discussed are that outdated tests are the basis for placement of EMH students, and that 46 of 50 students aspire to finish high school. Included are 22 teacher-written vignettes of students. (MC)

12. How Educators of Teachers of Science Evaluate Biology Teachers.
- Author

North Carolina State Dept. of Public Instruction, Raleigh. Div. of Development. and Dieter, Donn
- Abstract
This study attempted the following: a) to establish the criteria that judges used in the Outstanding Biology Teacher Award Program to evaluate biology teachers, b) to identify their various occupations, c) to establish whether or not criteria were valued significantly differently, and d) to determine if occupational status of judges is significantly related to such ratings. Regarding evaluation of biology teachers, it is possible to say that touchstones do exist which are significant for competent judges. Also, concerns for evaluator bias are real worries, for various judges do value specific criteria differently, and professors of science education and college biologists differ somewhat in how they value specific criteria. (Results of the evaluation of data are included in the text.) (Author/JA)

13. The Introduction of Biological Mensuration Techniques Through Simulation.
- Author
-
Michigan Technological Univ., Houghton. and Spain, James D.
- Abstract
New simulations for teaching quantitative biological techniques are now used at Michigan Technological University. Traditionally, such techniques work within a particular system and have the student assume certain initial conditions and employ appropriate constants. The computer generates time dependent data which are plotted. The student then repeats the process with changed conditions, observing the changed effect. In the new method, certain initial conditions are established randomly by the computer program and the student generates data to ascertain the unknown quantity, just as if he were measuring on a real system. The procedure is as follows: 1) The computer randomly generates a system parameter which the student must evaluate. The value is stored unrevealed to the student. 2) The computer generates data based upon the unknown constant, student determined input values, and the prepared simulation program. 3) The student uses the data to determine the unknown. 4) Finally, the student compares his derived value with the stored value. This report also provides a detailed simulation example, a procedural flow chart, and a list of other potential training simulation. (PB)

Robbins, Jerry H.
- Abstract
The public school system should be so maintained, as regards courses of study, as to keep abreast of progress generally and to meet the needs of the times, and to this end it is the administrative function of school board members and superintendents to create new courses and rearrange the curriculum in proper cases. A rule or regulation prescribing a course of study for a particular school does not require that any particular branch of study shall be compulsory on those who attend the school. Nor does such a rule or regulation deny a parent all control of the education of his child. This paper discusses the status of legislation on sex education according to (1) Mississippi statutory law, (2) statutory law in five other States, (3) major cases that have been in Mississippi courts, (4) the status of the case law on the subject elsewhere, (5) model legislation that has been proposed or recommendations for legislative action proposed by various agencies, and provides (6) recommendations developed on the basis of the material presented in the paper.

Duke Univ., Durham, NC. CONDUIT. and Warlick, C. H.
- Abstract
Computer-assisted instructional programs in seven content areas--mathematics, social science, physics, chemistry, biology, business and economics--are listed and described. These programs have been selected by content specialists as representative of the field and available for test purposes in connection with the regional network of Computers at Oregon State University, North Carolina Educational Computing Services, Dartmouth College, and the Universities of Iowa and Texas (CONDUIT). User reactions to these programs will be studied by researchers for two general purposes, the first of which is to evaluate the pedagogical and economic impact of computer-based techniques and to gather information on the factors associated with transferring these techniques to other educational environments. The second purpose is to create standards by which potential candidates for inclusion in the CONDUIT resource center may be judged and to determine which of these test programs are suitable for wide use.

Hunt, John D. and Lamkin, Bill
- Abstract
This study involved the use of an auto-tutorial system (plant taxonomy module) and its effect on cognitive learning. Student performance was investigated and compared for two groups, one of which received immediate reinforcement and feedback while the other group did not. Two biology teachers, from a group of 14, were randomly selected to participate in the study. Two groups of 24 students were randomly chosen from two lists of 150 students in the classes of these teachers. The first 24 students were the control group. Pre- and posttests containing 25 multiple choice responses were used to measure student performance. Data were analyzed using a multiple linear regression program. The investigators found (1) the I.Q. (obtained from data on the California Test of Mental Maturity in school records) of the students produced a significant difference in cognitive gains in both systems, and (2) the system employing immediate reinforcement and feedback produced significant and greater gains in cognitive learning than did the system without immediate reinforcement and feedback.

State Univ. of New York, Stony Brook. Huntington Computer Project., Visich, Marian, and Braun, Ludwig
- Abstract
The Huntington Computer Project has developed 17 simulation games which can be used for instructional purposes in high schools. These games were designed to run on digital computers and to deal with material from either biology, physics, or social studies. Distribution was achieved through the Digital Equipment Corporation, which disseminated teacher manuals, resource manuals, and student manuals to over 600 teachers and 25,000 students in 400 secondary schools during the 1972-73 school year; these target populations were expected to quadruple in the following year. Evaluation of the use of the computerized simulation games led to the conclusion that they made a significant contribution to learning. This was particularly true in situations in which students were denied direct experience with the phenomena being studied due to such problems as the students' inexperience with experimental techniques, the lack of laboratory equipment or time, difficulty or danger in obtaining adequate samples, and the impossibility of controlling extraneous variables in real life. Descriptions of six of the simulation games are appended to the report. (PB)

Glick, D. Marvin
- Abstract
Biology 101 was offered for the second time in the Personalized System of Instruction (PSI) format during the spring 1973 semester at North Country Community College. Course policy and procedure for the second semester were identical to fall 1972 except for policy changes outlined in Appendix C of that paper. Sixty students enrolled in the 1973 course, including five who withdrew from the 1972 course. An attempt is made here to identify shifts in student performance during 1973 in an effort to validate policy changes made at the close of 1972 and to identify additional changes that should be initiated. Well over 100 changes in course materials were made at the close of the 1972 semester. The 1973 students generally showed improved pacing over first semester students. The tables in this report contain: the comparison of grade-point averages (GPA) of biology 101 students; the average progress rate of 1972 and 1973 biology 101 students; average daily attendance in biology 101; relative laboratory grade earned compared with nonlaboratory grade; and eventual placement of 1972 biology 101 students. Appendices include course prerequisites, and the time extension policy. (Author/PG)

Wright, Delivee L.
- Abstract
Reported is a study of the verbal behaviors used by biology students in inquiry and noninquiry settings. The population for this study included 10 BSCS teachers who had enrolled for two semesters in an instructional program designed to make teachers aware of alternative skills and strategies of inquiry; to recognize those used in their own classrooms; to select, practice, and implement selected strategies; and to plan instructional activities to develop inquiry behaviors in students. This Instructional Staff Development (ISD) Program was designed for experienced teachers interested in improving inquiry learning in their classrooms. Each participating teacher was videotaped in one randomly selected class before and after instruction in the ISD program. Verbalized behaviors were coded using the Revised Inquiry Analysis Instrument. The "Self-pairing" of observations technique was used with measurement of the same individuals before and after treatment. Results showed the percentage of total teacher talk was significantly lower in the inquiry setting and student talk higher. Variety of verbal influence behaviors used by students was greater. The percentage of time spent verbalizing "data analysis and interpretation" and "procedures" was significantly greater in the inquiry setting. (Author/EB)

Gill, Elizabeth Deas
- Abstract
Parallel machine and manual literature searches on the subject of chemical evolution and the origin of life were compared on six characteristics: (1) precision, (2) recall, (3) novelty, (4) uniqueness, (5) time cost per citation, and (6) dollar cost per citation. The manual search outperformed the machine on precision, novelty, uniqueness, and dollar cost per citation although this was based on partial cost data for the manual search. There was little difference in recall between the two methods. For this subject area, "Chemical Abstracts", "International Aerospace Abstracts", and the Automatic Subject Citation Alert service were found to be the most effective sources for overall recall precision, novelty, and uniqueness. RECON and MEDLARS were found to be the most efficient in terms of times and costs. The study concludes that while the manual search had a slightly better overall performance, both modes are necessary for a comprehensive multi-disciplinary literature survey. (JG)

Mid-Continent Regional Educational Lab., Inc., Kansas City, MO. and Seymour, Lowell A.
- Abstract
Three domains of problems are the subject of this report: problems related to the nature of the Inquiry Role Approach (IRA) project implementation in field test classrooms, problems related to student performance associated with different kinds of extent of project implementation, and problems related to project student performance within the project and as different from comparison groups of nonproject students. Data were gathered by instruments sampling student perception of the existence of certain classroom practices, activity log forms, and monitoring on-site McRel staff. Data on project student performance were gathered by pre-, interim, and posttesting and activity feedback from teachers. Domains measured were: (1) cognitive inquiry process skill, (2) attitude, (3) social skill and small group inquiry activity, and (4) subject matter comprehension. IRA project students showed significant growth in all domains. Comparison nonproject students decreased over a year's time in measured cognitive inquiry skill and attitude while gaining slightly over IRA students in subject matter comprehension. (EB)

Del Mod System, Dover, DE., Delaware State Dept. of Public Instruction, Dover., and Banks, Dennis E.
- Abstract
This monograph includes guidelines for science courses in grades seven, eight, and nine, and for biology, chemistry and physics. Seventh grade Environmental Life Science is lab-oriented and based on a variety of student experiences. Course objectives are presented as well as the course outline. A multitext approach, with a suggested textbook list, is organized on reading ability level. The Earth Science Course, grade eight, focuses the attention of the student on the physical world in which he lives. Instructional materials suggested include films, filmstrips, and reference books and publications. The ninth grade curriculum exposes students to many physical science areas as well as a basic background for physics and chemistry students. A Materials List suggests texts and experiments that could be incorporated into the program. The major objectives of Biology I, the course content and supplementary materials are built around the BSCS green and yellow versions, an ecological approach. Supplementary materials include lab exercises, field exercises and films. Included in the chemistry curriculum are plans for an academic chemistry section and a terminal science section. Cotton and Lynch's "CHEMISTRY: An Investigative Approach" is used for academic students and Metcalfe, Williams, and Castka's MODERN CHEMISTRY, for the non-academic course. The textbook "Modern Physics" by Del, Metcalfe and Williams is used in the physics course. (EB)

47. Experiences with a Competency-Based Educational Approach to Reproductive Biology.

Utah Univ., Salt Lake City. and Brown, Thomas C.
- Abstract
A competency-based educational program for future physicians studying reproductive biology was developed at the University of Utah College of Medicine. The development took the form of a generic model specifying a linear sequence of steps, namely: assess competency needs, specify competencies, determine competency components and performance levels, identify and implement competency attainment procedures, establish assessment of compentency attainment, and validate all system components. A functional analysis was performed on each of these steps. In the future it is hoped to eliminate a time-bound curriculum in the sophomore reproductive biology course and substitute a set of self-learning modules where students would learn content independently, using their own personal choices of method of teaching.

- Abstract
During a 2-year period (1970, 1971) SDI (Selective Dissemination of Information) search profiles were written for 353 biologists and other research workers with a need for biological information in academic, industrial, and government research institutions. At the beginning of the experiment a questionnaire and interview survey was made of the information resources then being used by participants, with particular references to their usage of the printed Biological Abstracts (BA). A quantitative description of service performance was provided by the measurement of the following parameters: output sizes, recall ratios, precision ratios, coverage ratios, and novelty ratios. The relevance predictability of the enriched titles which appear on the BA Previews tapes was also studied. The users' reactions to the service were assessed by means of another survey at the end of the experiment. Correlations between quantitative performance measures and the users' assessment of the service, were examined. It was concluded that the results obtained in the project justified a further experiment in which biologists would be asked to make a payment toward the cost of the service, in addition to providing feedback.

- Abstract
The course of study represents the third of six modules in advanced crop and soil science and introduces the agriculture student to biological features of soil. Upon completing the two day lesson, the student will: (1) realize the vast amount of life present in the soil, (2) be able to list representative animal and plant life in the soil by size, and (3) be able to list some of the detrimental processes of soil organisms. The course outline suggests teaching procedures, behavioral objectives, teaching aids and references, problems, a summary, and evaluation. Following the lesson plan, pages are coded for use as handouts and overhead transparencies. A materials source list for the complete soil module is included. (MW)

50. Audio-Tutorial Project: An Audio-Tutorial Approach to Human Anatomy and Physiology.

Kingsborough Community Coll., Brooklyn, NY. and Muzio, Joseph N.
- Abstract
A two course sequence on human anatomy and physiology using the audiotutorial method of instruction was developed for use by nursing students and other students in the health or medical fields at the Kingsborough Community College in New York. The project was motivated by the problems of often underprepared students coming to learn a new field and by the time constraints caused by students' part-time status. An elementary biology course was divided into 28 learning modules (14 per semester). The program included a student study guide, taped lessons, small and large assembly sessions, an independent learning center with 30 carrels, and performance tests for each module. An analysis of the program is being planned that will use student questionnaires, an analysis of student time, and a comparison with students taking the human anatomy and physiology courses without audio tutorial instruction. The audio tutorial approach is an ideal method of fostering individualized learning, particularly for those students who have experienced academic difficulty. (WH)
