In this article, the author shares a very successful 50-minute inquiry-based physics lesson that uses only small metal cans, a bit of string, and the inquiring minds of middle schoolers. The topic of the lesson is wave motion and energy transfer. The intent of this article is to show that tests of student-generated hypotheses can be simple, quick,…

Many traditional classroom science and technology activities often ask students to complete prepackaged labs that ensure that everyone arrives at the same "scientifically accurate" solution or theory, which ignores the important problem-solving and creative aspects of scientific research and technological design. Students rarely have the…

The study examined the effect of supplementing laboratory instruction with problem solving strategy and or practical skills teaching on students' attitude toward chemistry. A total of 286 senior secondary class II students (145 males and 141 females) drawn from four local government areas in Oyo township in Oyo state, Nigeria, took part in the…

In Experiments 1A and 1B, students read a concise booklet containing 653 words and 6 illustrations describing the formation, propagation, and dispersion of ocean waves (concise group) or an expanded booklet containing 327 additional words and 5 additional illustrations describing relevant mathematical formulas and computations interspersed…

Trends in animal production have moved the industry toward large confined animal feeding operations (CAFOs). These CAFOs concentrate large amounts of manure-based nutrients in relatively small areas, which increases the risk of nutrient loss to the surrounding environment. In response to water quality concerns, P-based manure application…

This study examined the effect of scaffolding learning components in a computerized environment, for students solving qualitative science problems in a simulation of laboratory experiments. Four scaffolding components were identified (structural, reflective, subject-matter and enrichment) and used in different configurations to construct four…

The significant increase of English Language Learners (ELLs) in the United States raises complex questions about how to provide these students with access to high quality education that can improve both their content knowledge of school subjects and their English proficiency, particularly their academic English proficiency. The development of…

The main objective of the study reported in this paper was to construct a Lakatosian teaching strategy that can facilitate conceptual change in students' understanding of chemical equilibrium. The strategy is based on the premise that cognitive conflicts must have been engendered by the students themselves in trying to cope with different problem…

A dissertation study is described which employed action research methods and was conducted over four semesters of practice in a large first year undergraduate physics laboratory making extensive use of microcomputer-based laboratory (MBL) technology. Three cycles of action research are recounted, along with the resultant changes in goals,…

One of the major themes of reform in science education is that science should not be compartmentalized into single distinct disciplines but rather should be integrated. This study investigates the effectiveness of integrated programs and impediments to their success in K-12 education. The research was carried out collaboratively by California…

Teaching problem solving strategies and steps to first year college students enrolled in the pharmaceutical/chemical technology program as a part of their first year chemistry course focused on teaching the students the basic steps in problem solving and encouraging them to plan carefully and focus on the problem solving process rather than to…

This paper presents a synthesis of several studies that support the hypothesis that properly scaffolded design problems lead to the types of convergent thinking and knowledge integration that have been difficult to achieve in the Computer Supported Intentional Learning Environment (CSILE) system. The focus is on a middle school science unit on…

Research in science and mathematics education has indicated that students often use inappropriate models for solving problems because they tend to mentally represent a problem according to surface features instead of referring to scientific concepts and features. The objective of the study reported in this paper was to determine whether 34 Israeli…

Two instructors at Bunker Hill Community College in Massachusetts have developed a unit of study designed to teach biology as a process, improve students' critical thinking and reasoning skills, and provide students with the opportunity to express these skills in writing. The instructional strategies employed in the unit are superimposed on a…

This paper attempts to show that it is possible to analyze a problem solving protocol in which the subject spontaneously generates a series of analogies. The qualitative physics problem given to the subject describes a situation where that which is unfamiliar is often solved by relating it to several analogous situations that are more familiar.…
