Traditional practical work for higher education in STEM subjects is under pressure from rising student numbers and a desired increase in active learning. Investing in more buildings and staff is financially challenging, while stretching existing resources affects outcomes, health, and participation. A more pragmatic approach is to embrace a less…

Renal clearance, the volume of blood cleared of a substance in a particular time period, is commonly recognized as one of the most difficult concepts in physiology. This difficulty may in part reflect the quantitative nature of renal clearance since many life sciences majors perceive that mathematics is irrelevant to their discipline. Students may…

The aim of this learning exercise was to harness current interest in zombies in order to educate audiences about the epidemiology of infectious disease. Participants in the activity were provided with an outbreak scenario, which they then used as the basis of play-based activities. By considering the mode and speed of transmission, size of…

Several classroom activities using a model of a seashore and an oil spill demonstrate the basic properties of oil spills in oceans. Students brainstorm about how to best clean up the mess. They work in teams, and after agreeing on how they will proceed, their method is tested by measuring the amount of oil removed and by rating the cleanliness of…

The history of learning biology through distance education is documented. A review of terminology and unique problems associated with biology instruction is presented. Using published research and their own teaching experience, the authors present recommendations and best practices for managing biology in distance-based formats. They offer ideas…

Literacy remains an area of concern in early secondary education in Scotland (ages 12-14), with recent research suggesting a continued decline in attainment levels. As literacy underpins learning, interdisciplinary and collaborative approaches to teaching literacy are now being emphasized through the new Curriculum for Excellence that aims to…

Describes an activity for use with a chapter on dinosaurs, prehistoric life, or digestion in which children make simulated dinosaur stomachs to gain hands-on experience about the theory of gastroliths, or stomach stones. Presents teacher information about the digestive processes in birds and dinosaurs. Discusses materials needed, objectives,…

Presents low-cost learning activities to help teach elementary students about the earth's magnetic field. One project has students make a model of the earth's magnetic field. Another has them experiment with magnetism. (SM)

Outlines an activity in which students clarify choices among personal and ecological values. Variables (including concerns of the natural environment and personal income) are rated from high to low within a total constraint set by the instructor. Uses of the activity in a college geology course for nonscience majors are discussed. (DH)

Presents activities to familiarize junior high school students with the processes behind and reasons for volcanism, which is generally a planet's way of releasing excessive internal heat and pressure. Students participate in the creation of four important volcano-related simulations: a lava flow, a shield volcano, a cinder-cone volcano, and a…

Describes an activity in which students investigate the effects of selected natural and synthetic substances on the rate of apple browning. Includes background information for the teacher, a list of necessary materials, and student instructions. (KR)

Presents a simple activity that simulates natural selection working on random mutations through many generations. (PR)

Describes an activity to simulate the geometries of a spreading pathogen such as HIV throughout a generation. Students exchange "bodily fluids" three times and are then tested for the presence of "infection." Materials used include base solutions (NaOH or KOH), phenolphthalein (pH indicator), clear plastic cups, and an eye dropper. (PR)

Provides rationale for and examples of a game (Mastermind) which fosters the development of a systematic approach to problem solving. Includes a brief summary of an experiment with 50 high school students indicating value of the game. (JN)

Outlines some general considerations relating to gaming and simulation for educational purposes. Provides an example of a simulation and some examples of commercially available materials. Includes a short bibliography related to this topic. (DS)
