Integrates concept mapping into the chemistry laboratory and requires students to construct a concept map for each experiment. Reports a decrease in student questions concerning set up and procedure. Recommends using computer software such as Chem Sketch 5.0 which is free and available from the Internet. (Contains 15 references.) (YDS)

Describes visual experiments that illustrate some basic concepts in chemistry and their principles. (KHR)

Investigates whether replacing a single traditional laboratory activity with a widely-used, non-microcomputer-based laboratory, research-based activity could produce improved conceptual understanding of a topic in electricity. Shows that a single instructional experience utilizing the research-based tutorial materials is superior to a traditional…

Discusses some aspects of campus research facility construction that require specialized construction expertise, and which should be considered when reviewing construction proposals. (EV)

Describes an innovative science program that trains teachers to use their own schoolyards as environmental laboratories. (MKR)

Describes the Savannah River Site, a national environmental research park that shelters wild animals and idle nuclear reactors. Outlines research conducted at the site that focuses on the recovery of ecosystems after disturbance related to the operation of nuclear reactors and other land uses. (LZ)

Describes an instrument developed to assess students' or teachers' perceptions of five dimensions of actual or preferred classroom environment: student cohesiveness, open-endedness, integration, rule clarity, and material environment. Instrument is included in the appendix. (ZWH)

Describes a toy shaped like a bird that has an intuitively astonishing property: no matter how far away from equilibrium it is moved, it oscillates back to equilibrium. The behavior of this physical system is explained and is used to illustrate the concept of mechanical stability and the usefulness of making simple, idealized models for describing…

Draws data from student responses to the Science Laboratory Environment Inventory (SLEI) and a curriculum analysis of the implemented laboratory tasks. Involves biology, chemistry, and physics students (N=387) in 20 classes in Tasmania, Australia. Contains 23 references. (DDR)

Describes how scientists use representations and tools in the chemistry laboratory. Derives implications from these findings for the design of educational environments. (Author/CCM)

A new state-of-the-art marine science laboratory at Eckerd College (Florida) is a study in the power of research, teamwork, attention to detail, and cost control. A redundant piping system brings sea water directly to the students. Once a week the pipes that previously held sea water are flushed and refilled with fresh water. (MLF)

Presents a chemistry activity that introduces students to one type of chemical bond by developing the integer operation concept of zero pairs. Leads to an activity of combining drops of 0.3 molar solutions to form six different colored precipitates from five solutions. (ASK)

Applies chemistry to earth science, uses rocks in chemistry laboratories, and teaches about transition metal chemistry, oxidation states, and oxidation-reduction reactions from firsthand experiences. (YDS)

Conducts an action research investigation to determine which type of student benefits more from inquiry-based science laboratories. Designs two labs on diffusion and osmosis using both traditional and inquiry-based approaches and assesses student learning in these settings. (YDS)

Discusses the importance of environmental chemistry and the use of laboratory exercises in analytical and general chemistry courses. Notes the importance of lab work in heightening student interest in coursework including problem-based learning in undergraduate curricula, ready adaptability of environmental coursework to existing curricula, and…
