University and high school students not pursuing a science, technology, engineering, and/or mathematics (STEM) course of study demonstrate less developed scientific reasoning than their STEM-based peers. Previous studies show that the majority of non-STEM students can be classified as either concrete operational or transitional reasoners in…

The Lawson Classroom Test of Scientific Reasoning (LCTSR) was used to gauge the relative effectiveness of three different methods of pedagogy, "Reading, Presenting, and Questioning" (RPQ), "Experimenting and Discussion" (ED), and "Traditional Methods" (TM), on increasing students' level of scientific thinking. The…

Describes a new physics program which depends mainly on student performed experiments and investigations, and subscribes to Piaget's learning and developmental theories. (GA)

Discusses briefly Piaget's views on intellectual development as related to science teaching. Describes intellectual activities observed in science classrooms and shows how specific science lessons can be designed to encourage cognitive development. (GA)

A course is described that is designed to encourage exploration, conceptual invention, and expansion of an idea. Results are given that relate to curricular experimentation with chemistry. (SA)

Reviews the objectives of laboratory work in chemistry education, current laboratory practice, and factors likely to impact on the nature of laboratory work in the future. Proposes that more investigation-style laboratory work be provided in order to foster the development of students' investigation skills. (Author/MKR)

The author describes activities he uses with secondary school science students to learn about their reasoning. (Author/SA)

A learning cycle consists of three phases: exploration; conceptual invention; and expansion of an idea. These phases parallel Piaget's functioning model of assimilation, disequilibrium and accommodation, and organization respectively. The learning cycle perceives students as actors rather than reactors to the environment. Inherent in that…

Many educators assert that the acquisition of thinking skills by students is of primary importance to science education today. This study was designed to examine the effect of an instructional approach on achievement in science process skills when compared to a more conventional method of science instruction. The DIAL(SPS)2, a directed approach to…

Describes an investigation of the strategies used by 47 high school students in solving volumetric analysis problems in chemistry. Reports that students in the high ability group mainly used the "formula" approach, while those in the low ability group tended to use the "proportional" approach to problem solving. (TW)

Teaching creative thinking can be accomplished by activities in which the teacher asks questions of the students which require divergent thinking. The activities in this article do not require equipment, supplies or manipulatives. They consist of questions, possible student answers, and suggestions for follow-up. (CW)

In an effort to improve students' interests in science and science courses, a study was conducted in Israel to evaluate students' attitudes towards science relative to two chemistry curricula. These curricula were Chemistry for High Schools (CFH), and Chemistry--A Challenge (CAC). The CFH program was mainly designed for science-oriented students…

A learning cycle consists of three phases: exploration; conceptual invention; and expansion of an idea. These phases parallel Piaget's functioning model of assimilation, disequilibrium and accomodation, and organization respectively. The learning cycle perceives students as actors rather than reactors to the environment. Inherent in that…

A developmental investigation of the ability to control variables was conducted. One or two logically similar physics problems were individually administered to 120 subjects age 12 to 14. The problems involved either familiar or unfamiliar variables. Each problem was presented in three different informational formats. Success on the problems in…

A study was designed to test the hypothesis that a descriptive-type learning cycle was insufficient to stimulate students to reason at a reflective level or to develop an understanding of, and facility with, the processes of scientific investigation. In order to test the hypothesis, four classes of ninth-grade physical science students (n=100)…
