Every schoolyard presents a wealth of opportunities for science exploration. To capitalize on this resource, the authors developed an activity in which students assessed whether their schoolyard could provide a viable habitat for treefrogs. This inquiry-based module was composed of three lessons: A Hoppin' Treefrog Adventure, Field Research Means…

In this article, the author presents five problems that are representative of some of the "movie problems" that he has used on tests in various courses, including reactor design, heat transfer, mass transfer, engineering economics, and fluid mechanics. These problems tend to be open-ended. They can be challenging and can often be worked a variety…

From children's viewpoints, what they experience in the world is what the world is like--for everyone. "What do others experience with their senses when they are in the same situation?" is a question that young children can explore by collecting data as they use a "feely box," or take a "sensory walk." There are many ways to focus the children's…

Measuring the mass of many pennies has been used as an easy way to generate data for exercises with statistical analysis. In this general chemistry laboratory the densities of pennies are measured by weighting the pennies and using two different methods to measure the volumes. There is much to be discovered by the students on the variability of…

The changes that have taken place in the organic chemistry laboratory course since 1980s are reviewed with reference to the quantity and diversity of discovery-based experiments available to date. The data illustrates that significant progress is towards accomplishing dramatic changes such as the almost universal adoption of microscale, the use of…

The population growth together with the unsustainable consumption pattern is putting increasing stress on the planet's natural resources. The increasing realisation that humans are harming the environment is taking the form of a global movement intended to change behaviour towards sustainability, now recognised as a framework that links humans to…

Dynamic inquiry learning emphasizes aspects of change, intellectual flexibility, and critical thinking. Dynamic inquiry learning is characterized by the following criteria: learning as a process, changes during the inquiry, procedural understanding, and affective points of view. This study compared the influence of open versus guided inquiry…

BECAUSE OF THE EVER INCREASING EXPANSION OF KNOWLEDGE AND CULTURAL CHANGES, TEACHING CHILDREN TO DISCOVER (DEFINED HERE AS THE ACQUISITION OF AN ABILITY TO FORMULATE AND SOLVE PROBLEMS) SHOULD BE GIVEN CONSIDERABLE SIGNIFICANCE AS AN EDUCATIONAL GOAL. THE PURPOSE OF THIS REPORT IS (1) TO CLARIFY CERTAIN ASPECTS OF TEACHING CHILDREN TO DISCOVER,…

In the form of a discussion between faceless people, this booklet concerns discovery learning and its advantages. Subjects covered in the discussions are: Introducing the Discovery Method; An Experiment with British Railways; The OECD Research Projects in U.S.A., Austria, and Sweden; How the Discovery Method Differs from Other Methods; Discovery…

Describes the process of play as a basis for language arts learning by gifted children. (DD)

Assesses the acceptance of and expressed preference for varying levels of salt in soup among children three to six years of age. (HOD)

This paper reviews and analyzes the term "exploration" as used with selected models associated with the instruction of children. (MT)

The problem of determining the number of squares having vertices at pegs on geoboard is considered. (DT)
