Early approaches to science instruction in the United States consisted mainly of daily recitations from books and lectures. Use of the laboratory was unheard of prior to the mid 1800s. Physical materials and specimens, if used at all, were a means of verifying book or lecture information. But by the late 1800s, laboratory instruction became very popular because it was felt that firsthand observation and manipulation were useful in “disciplining” the mind. The idea of mental discipline stemmed fr...

When we first met in 1962 Bob Karplus was a theoretical physicist and I was an Assistant Superintendent of Schools. We both had a second love (at the time) called elementary science education and our chance meeting as consultants to an educational toy company redirected my career, and enhanced Bob’s commitment to science education. It resulted in what became known as the Science Curriculum Improvement Study or SCIS which in Latin we later found out means to know. According to our editor the SCIS...

In this chapter, the focus of Robert Karplus’s work on students’ reasoning will be revisited. The emphasis on exploring and understanding students’ reasoning in multiplicative conceptual domains, beyond the elementary school, is central in the mathematics and science education-related work of Robert Karplus. About 30 years ago, at a time when the emphasis in mathematics and science education research was on students’ achievement test scores and related statistical group averages, Robert Karplus ...

The late 1950’s witnessed the beginning of two revolutions, one in science with the launch of the first space satellite, and the other in education with the launch of a major paradigm shift in the teaching of elementary science. The two were intimately connected. The Soviet Union’s dramatic launch of a satellite prompted politicians, educators, and scientists to focus on the lack of a scientifically literate public in the United States and its implications for national security and scientific pr...

The Congress of the United States created the National Science Foundation (NSF) in 1950. It stipulated that the Foundation would have two missions: to support basic research in science and to improve science education. From the inception, the first of these missions was pursued enthusiastically, but not the second. While there was considerable interest within the Foundation for support of education in science at the Ph.D. level, there was little enthusiasm for becoming involved in undergraduate ...

The study deals with qualitative features of proportional reasoning on dimensional intensive variables by eleven and thirteen year-old students. These features include types of comparison and types of strategies employed. Four proportional problems, varying in numerical and referential content were administered to 116 eleven year-olds and 137 thirteen year-olds. No significant age effect was found. The relative frequencies with which the type of comparison and various strategies were used was gr...

Three mathematical reasoning tasks (proportions, reasoning with an unknown, and a spatial reasoning task), and an attitude interview were individually administered to 260 8th grade students from three predominately minority urban schools. The three schools and neighborhoods varied in educational advantages as well as in socioeconomic characteristics. An additional 60 students, from a middle class and predominately white school in which a similar study had been conducted previously, was included ...

Two hundred forty eight adolescents from grades 6 and 8 were given a proportional reasoning task and a battery of eight cognitive style, ability, and attitude measures. The problems in the proportional reasoning task varied in referential content and numerical structure. The cognitive ability and style dimensions examined consisted of: Crystallized intelligence, fluid intelligence, field dependency, divergent thinking, visualization ability, and M capacity. An age x sex x content x structure ANO...
