In this report we examine students' perceptions of the implementation of carefully designed curriculum materials (called modules) in linear algebra courses at three different universities. The curricular materials were produced collaboratively by STEM and mathematics education faculty as members of a professional learning community (PLC) over…

The aspect of the Unified Science and Mathematics for Elementary Schools (USMES) project described in this paper was undertaken in an effort to observe the problem solving behaviors of elementary school children. The Notebook Problem consisted of presenting a student with three notebooks arranged so as to differ from each other in terms of such…

This is the student's text for one of the units of the Intermediate Science Curriculum Study (ISCS) for level III students (grade 9). The chapters contain basic information on the processes that shape the earth, activities related to the subject, and optional excursions. A section of introductory notes to the student discusses how to use the book…

This is the teacher's edition of one of the eight units of the Intermediate Science Curriculum Study (ISCS) for level III students (grade 9). This unit focuses on processes that shape the earth. Optional excursions, in addition to the activities, are suggested for students who wish to study an area in greater depth on an individualized basis. An…

This is the student's edition of the Record Book for the unit "Crusty Problems" of the Intermediate Science Curriculum Study (ISCS) for level III students (grade 9). Space is provided for answers to the questions from the text as well as for the optional excursions and the self evaluation. An introductory note to the student explains the…

In this set of six booklets on graphing, intermediate grade students learn how to choose which kind of graph to make; make bar graphs, histograms, line graphs, and conversion graphs; and use graphs to compare two sets of data. The major emphasis in all Unified Sciences and Mathematics for Elementary Schools (USMES) units is on open-ended,…

In this set of five booklets on measuring, primary grade students learn how to use a stopwatch, choose the correct tool to measure distance, use a trundle wheel, make a scale drawing, and find the speed of things. The major emphasis in all Unified Sciences and Mathematics for Elementary Schools (USMES) units is on open-ended, long-range…

In this set of five booklets on measuring, intermediate grade students learn how to use a stopwatch, choose the right tool to measure distance, use a trundle wheel, make a scale drawing, and find the speed of things.

In this set of three booklets on simplifying data, primary grade students learn how to round off data and to find the median and average from sets of data. The major emphasis in all Unified Sciences and Mathematics for Elementary Schools (USMES) units is on open-ended, long-range investigations of real problems. In most instances students learn…

In this set of six booklets on simplifying data, intermediate grade students learn how to tell what data show, find the median/mean/mode from sets of data, find different kinds of ranges, and use key numbers to compare two sets of data. The major emphasis in all Unified Sciences and Mathematics for Elementary Schools (USMES) units is on…

The major emphasis in all Unified Sciences and Mathematics for Elementary Schools (USMES) units is on open-ended, long-range investigations of real problems. Since children often design and build things in USMES, 26 "Design Lab" cards provide information on the safe use and simple maintenance of tools. Each card has a large photograph of…

This is the teacher's edition of the Record Book for the unit "Crusty Problems" of the Intermediate Science Curriculum Study (ISCS) for level III students (grade 9). The correct answers to the questions from the student text are recorded. An introductory note to the teacher explains how to use the book. Answers are included for the…

In this set of two booklets for primary grades, students learn how to make a home for their animals (amphibians, insects, fish, crayfish) and a home for their rodents (hamsters, guinea pigs, gerbils, mice). The major emphasis in all Unified Sciences and Mathematics for Elementary Schools (USMES) units is on open-ended, long-range investigations of…

In this set of four booklets on collecting data, primary grade students learn how to record data, do an experiment, make an opinion survey, and choose a sample. The major emphasis in all Unified Sciences and Mathematics for Elementary Schools (USMES) units is on open-ended, long-range investigations of real problems. In most instances students…

In this set of six booklets on collecting data, intermediate grade students learn how to collect good data, round off and record data, do an experiment, make an opinion survey, and choose a sample. The major emphasis in all Unified Sciences and Mathematics for Elementary Schools (USMES) units is on open-ended, long-range investigations of real…
