SUMMARY

The Secondary School Mathematics Curriculum ImprovementStudy (SSMCIS) has two main objectives:

1) To formulate and test a unified secondaryschool mathematics program (7 - 12) that willtake capable students well into currentcollegiate mathematics;

2) To determine the education required byteachers who will implement such a program.

To inaugurate the study, leading United States and Europeanmathematicians and educators met in June 1966 to formulatea position paper suiting the aims and procedures of thestudy, to construct a flow charted analysis of the pro-posed 7 - 12 mathematics courses, and to make detailedrecommendations for the mathematical content of Course I.Using thin detailed syllabus as a guide, a team of eightmathematics educators wrote a textbook for Course I duringthat summer. Each chapter was written by one writer, re-viewed by the other writers and a consulting mathematician,and then revised for printing. Teachers' guides andsolutions to exercises were written and distributed tothe teachers.

In each subsequent year (1967, 1968) a two-week Juneworking conference was held to review and revise the pre-vious year's experimental text and to make specific re-commendations for the content and teaching; of a new course-Course II and Course III, respectively. As in the firstyear the writing team used the chapter guides dcvelopedby the June working conference to write the new texts forthe following year.

Six junior high schools in the metropolitan New York areahave participated in the experimental teaching of Courses I,II, and III from the initiation of the e;:periment. Each ofthese schools designated a team of two capable and interest-ed teachers who taught all the pilot classes using the ex-perimental textbooks. Each summer, while new materialswere being written, six weeks of instruction was given tothese teachers in preparation for teaching the new SSMCIScourse. This instruction included 50 hours in the funda-mental concepts underlying the unified mathematics programand 50 hourb in contemporary methods of teaching thoseconcepts.

Page 7: DOCUMENT RESUME SE 010 881 - ERICDOCUMENT RESUME. 24n. SE 010 881. Fehr, Howard F. Secondary School Mathematics Curriculum Improvement Study. Final Feport. Secondary Scnool MatheNatics

The experimental teaching was evaluated in three ways. Thedirector and project staff members made frequent visits tothe classes for direct observation. The students weretested by examinations - prepared by the project staff - de-signed specifically to measure learning of important newconcepts introduced in the courses. Teachers, staff, andconsultants met at full day conferences to discuss progressand problems in the experimental teaching.

lir:sults of the experimentvl Lobehing have shown that thenew mathematics eourses, based on fundamental concepts and9tructures, give promive of veeting the expectations of theproposed six year pogvam,

In September 1965, the Commissioner of Education, Departmentof Health, Education, and Welfare, Office of Education,approved for support for a period of 18 months the SecondarySchool Mathematics Curriculum Improvement Study (SSMCIS),an experimental study whose objective would be the construc-tion of a unified school mathematics curriculum for gradesseven through twelve.

In June, 1967, continuation of this support was grantedfor an additional 36-month period ending June 30, 1970.This is a report of the activities and findings of theSSMCIS during this latter period, covering the writing andteaching of experimental Courses II and III, the revisionand further, teaching of Courses I and II, and the finalrevision of Courses I and

Plare1:1212s2irsoIn June 1966 a group of nightprIn learl;ng United States andEuropean mathematicians and educators met for 20 days tooutline the scope and sequence of a six year unifiedsecondary school mathematics program. The first half ofthe conference was devoted to producing a complete flowcharted annlynis of the proposed course. When topicsplanned for the nerenth grade were expanded in workingpppers which outlined the mathematical content of eachtextbook chapter and made specific suggestions for writingand teaching these ideas,

Writing, of Courses I, II, and III

During July and August 1966, a team of eight mathematicaleducators wrote the textbook for Course I, using thesyllabus produced in June as a guide. Each textbookchapter was written by one writer, reproduced for reviewby the other writers and consulting mathematicians, andthen rewritten, incorporating the revewers, suggestions.Teachers' guides and solutions to exercises were written foreach chapter. These notes, mimeographed and distributed toteachers of experimental classes, included discussions offundamental mathematical ideas underlying each chapter,hints for possible class activity to accompany reading ofthe text, and suggested time allotment to the varioustopics, The Course I textbook was then published in threevolumes,

To initiate the detailed planning for Course II and forthe revisions of Course I, a pre-planning session was heldon March 11-12, 1967. The recommendations of this pre-planning group were considered in detail at a workingconference held in June, 1967, at which the full group of

writers and consultants wan present. Thin group produced adetailed set of writing guidelines, which were then usedby the summer writing teams to produce the text materialsfor experimental Course II and to revise Course 1.

Beginning with a pre-planning meeting in December, 196y,and followed by a full working conference in June, 1968,a similar procedure wan used to plan and write experi-mental Course III, to rewrite Course II, and to finalizeCourse I. In addition, in order to make the fullestpossible use of the experience of two years of teachingCourse I, ten of the experimental teachers re-wrote andexpended the original teachers' commentaries for Course I,which had been originally written by the authors of thevarious chapters. These chapter-by-chapter commentarieswere then bound into a single volume and made availablefor public use along with the texts.

In 1969, the writing actIvitie:7 of the SSMCTS, sunoortedby the Office of Education, consisted of rewriting CourseIII and making final revisions in Course II. Again, asin the previous year, a'group of teachers of experimentalclasses worked during the summer, to rewrite the teacherscommentaries for Course II, which were then printed in asingle volume for use in conjunction with the texts,

The texts and Teachers Commentaries for ,.;ourses I and IIti each in two volumes) are now available for widespreadclassroom use, and are published and distributed by theTeachers College Press. When revision of Course III, nowunder way, is completed, the two volumes of the Course IIIi.ext and the accompanying Teachers Commentary will besimilarly available.

Education of Teachers

Each summer, beginning in 1966, the teachers of experimentalclasses have phrticipated in a six-week program of specialstudy at Teachers College, designed to prepare them toteach an experimental course in the following school year.This program of study wan in two parts. The first was acourse in the mathematical subject areas underlying theexperimental course content, such as: abstract algebra,linear algebra, transformation geometry and probability.These subjects were taught from a modern and unified pointof view, The second part of this program w 5+ course inpedagogical methods of teaching secondary mathematics as aunified branch of knowledge, with special emphasis In thespecific structures and principles to be covered in thefollowing year of experimental teaching.

Teaching Courses

Six junior high schools in the New York Metropolitan areahave taken experimental classes through Course I, II, andIII. Five of these classes covered the text material inits first experimental revision. Another fifteen experi-mental classes have completed these three courses in therevised versions and another fifteen non-experimentalclasses in these schools have completed both Course I and IIin their final revisions, Since the SSMCIS program is atpresent deals ned for those students in roughly the top 15%of their class with respect to mathematical ability, theoriginal selection of students for the twenty experimentalclasses was made by the participating schools with priormathematics achievement and scores on aptitude tests asmain criteria.

Because the teachers of pilot classes were working as a teamin the experimental class, they were often able to helpeach other with difficulties that arose in understanding orteaching the new material. Having had this year of teamteaching experience, the teachers are now prepared to teachCourses I, TI. and III on their oNn.

During the :.1:shonl year, the director and project staffmembers made frequent personal visits to observe theexperimental teaching, Each clans was observed at leastfour times. Visits to these schools included discussionswith the teachers and administrators concerning progressand problems with the experimental course,

The teacher- were further assisted by several full-daymeetings nt Teachers College where teaching problems werereviewed with selected consultants and the project direct-or, At these meetings many teaching difficulties wereresolved and valuable criticisms of the textbook weregathered.

Evaluation of Courses 1.1 II, and III

The six year mathematics program introduces many newconeepts into the secondary school mathematics curriculumand in',egrates both stnnderd and new topics in a globalorganization not characteristic of existing programs,Student achievement in such a program cannot adequately bemeasured using conventional standardized tests, For thisreason, student learning was tested by extramural examina-tions constructed by the project staff,

To guide construction of these and future measurementinstruments, the textbooks were analyzed to produce ataxonomy of cognitive objectives. This taxonomy sided in

delineating goals of instruction in terms of subject matterand related behaviors. The categories of behavior appearin Table I,

Each year, two examinations were prepared; one for a mid-year evaluation, and one for an evaluation at the end ofthe year. These instruments were used as n measure of theteachability as well as of the learning of the preparedcontent. They also guided the revisions that were sub-sequently made.

Alhough achievement on standardized traditional mathematicstests was not accepted as a measure of the success of theexperimental program, it was of interest to determine atthe start whether or not study in the experimental CourseI affected learning of traditional topics, To accomplishthis objective all students were administered the Sequen-tial Test of Educational Progress - Mathematics, Form 3A -in September 1966 and again in September 1967, The testresults clearly show that students in the project classessuffered no decline in mathematical skills when comparedwith students studying more traditional programs, More-over, the achievement of these students on the projecttests shows that they were leerning to work manynew and powerfUl mathematical tools not r, part of thetraditional mathematics fare of seventh gradora,

Future Activity

The Secondary School Mathematics Curriculum ImprovementStudy recei-ved support from the National Science Poundationin June 1969 to continue designing and experimenting witha unified secondary school program for college cApablestudents in the senior high school. This support hasenabled the project to produce Course IV in the six yearsequence an to begin planning for Course V and VI,

Course iv. whir) had been written in the summer of 1969,was pilot-tentcd in five experimental schools during the190-1970 school year. As a result or this experil.entation,Course IV will be revised during the summer of 1970and will be available by the early Pall (1970). Afterfurther testing, the final version will be availableby September 1971.

A tentstive outline for Course V was developed durinvtwo day conference of the advisory council in Januar:, 1970,lhis outline was expanded during a nine day conferenceof writers and consultants into detailed guides for thewriters or the chapters in course V. This eonrse will bewritten dcrin07. the summer of 1070 and experimented with infive schooln dnring 107u.

Page 13: DOCUMENT RESUME SE 010 881 - ERICDOCUMENT RESUME. 24n. SE 010 881. Fehr, Howard F. Secondary School Mathematics Curriculum Improvement Study. Final Feport. Secondary Scnool MatheNatics

The planning for and writing of Course VI will follow asimilar procedure to that outlined for Course V with class-room testing during the 1971-72 school year.

By the end of the academic year 1973, the SSMCIS will havecompleted its task - to make a reconstruction of thesecondary mathematics curriculum by presenting the subjectAS an integrated body of knowledge reflecting the spiritof --ntemporary mathematics.

Conclusions and Recommendations

After 1 years of classroom experimentations with studentsselected in the upper 15 to 205 or academic ability andtaught by interested classroom teachers with special train-ing in subject matter and pedagogy, a new curriculum inmathematics has been designed for the junior high schoolstudy, grades seven, eight, and nine. This curriculumbreaks down the traditional barriers separating arithmetic,algebra, and geometry, mod unifies the study through thosefundamental concepts underlying all the branches, namelysets, relations, functions, and operations. The resultingcurriculum is like a double helix in which the importantstructures - group, ring, field and vector apace - formone strand, while the other strand consists of the impor-tant realizations: the number systems and the severalgeometries; synethetic, coordinate, vector, and transfor-mation. interwoven with both these strands are the activi-tien and applications including the study of function,conditional sentences, statistics ard probability.

Students who complete this three year program are advancedin knowlede more than one year beyond the present collegepreparatory program. This in accomplished by eliminating agreat deal or traditional content that, today is of little orno value in further study or applicstton or mathematics.The increase in learning is also orolwht shout by the unifi-cation of all the study under the more r,c!neral concepts andstructures of conteporary mathematics.

The teachability has been tested and verified, each courseunlerrpIng, thr.e yearn of thorough examinations and revi-sion into its present form. Concomitantly, five doctoralstudies researching the lecrning and teaching, aspects ofthe program were completed. These studies were ..tarried outby the research assistants associated with the project.They were:

A study in one school has shown that the same material canbe learned by students of average ability, if pursued at aslower rate over a longer period of time.

It is strongly recommended that the program developed bySSMCIS be reexamined for adaptation as a curriculum for allstudents in the junior high school. It is also recommendedthat the SSMCIS program serve as a basis for re-examiningthe pre-service mathematics education of prospective juniorhigh school teachers of mathematics. For these teachers,far more attention must be given to abstract and linearalgebra, and to geometry of a modern variety, with lessstress on advanced analysis. Lastly it is recommended thatthe unified approach be extended throughout the senior highschool study to give college preparatory students an ad-vanced knowledge of all aspects of mathematics on enteringcollege and not only that of the calculus.
