Discusses the use of problem-solving activities in elementary-level science lessons. Sample activities include "Sparkling Christmas Presents,""Who Left the Message?," and "Parachute Descent". (WRM)

Describes an informal study that was conducted to determine if students who were taught critical thinking skills improved their course grades. Finds that the experimental group, who were taught critical thinking skills in an introductory psychology course, did significantly better than the control group, who took a humanities course that stressed…

The use of professional software is an integral part of a student's education in the mining engineering curriculum at The Pennsylvania State University. Even though mining engineering represents a limited market across U.S. educational institutions, the goal still exists for using this type of software to enrich the learning environment with…

A teaching unit on genetics and human inheritance using problem-solving methodology was undertaken with fourth-level Spanish Secondary Education students (15 year olds). The goal was to study certain aspects of the students' learning process (concepts, procedures and attitude) when using this methodology in the school environment. The change…

The main goal of most physics textbooks is to develop declarative and procedural knowledge. Exercises provide pupils with opportunities to apply this knowledge. However, when confronted with more complicated exercises many pupils experience difficulties in solving them. A computer program about the subject of forces was developed containing hints…

For students to develop an understanding of functions, they must have opportunities to solve problems that require them to transfer between algebraic, numeric, and graphic representations (transfer problems). Research has confirmed student difficulties with certain types of transfer problems and has suggested instructional factors as a possible…

In foundation biochemistry and biological chemistry courses, a major problem area that has been identified is students' lack of understanding of pH, acids, bases, and buffers and their inability to apply their knowledge in solving acid/base problems. The aim of this study was to explore students' conceptions of pH and their ability to solve…

This article describes an activity where children develop reasoning skills by using mathematical clues to decide whether there is one, more than one, or no solutions to a problem. (Contains 4 figures.)

A protein lacking one of the 20 common amino acids is a protein lipogram. This open-ended problem-based learning assignment deals with the evolution of proteins with biased amino acid composition. It has students query protein and metabolic databases to test the hypothesis that natural selection has reduced the frequency of each amino acid…

Psychology students frequently have misconceptions of basic concepts in operant conditioning. Prior classroom observations revealed that most students defined positive reinforcement as reward and equated negative reinforcement and punishment. Students also labeled positive reinforcement as rewarding good behavior and negative reinforcement as…

The article discusses the use of Marshall Rosenberg's Nonviolent Communication method to teach children who have emotional and behavioral challenges inside the music classroom. The method consists of using direct and nonjudgmental language, expressing feelings and needs, and finally making a request as opposed to a demand.

The textbook remains a central resource for teaching and learning mathematics in many secondary classrooms, however, its effectiveness is open to question. In this article, the author argues three things: (1) that there can be a substantial disjunction between the assumptions and content of mathematics textbooks and the knowledge and experiences…

Over the past 20 years, teachers have been under continuous pressure to increase students' academic achievement gains. The No Child Left Behind Act of 2001 (NCLB), the latest effort in the 20+-year-old school reform movement, is a federal mandate that demands in part that school districts implement science-based instructional strategies to ensure…

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…

Conjoint behavioral consultation (CBC) is an indirect form of service delivery in which parents and teachers collaborate to meet the academic, social, and behavioral needs of children. The purpose of this study was to evaluate CBC as a method of providing behavioral support for two students with emotional and behavioral difficulties (EBD) in…
