Computers In The Science Classroom, Piroz Mohseni

Iowa Science Teachers Journal

Computers have become an integral part of the education system, and computer literacy is an important asset for any college student. Many students find that their exposure to computers at the high school level was not satisfactory. Thus they hesitate to enroll in computer enhanced mathematics or science courses at the college level. This paper discusses some of the avenues for secondary science instructors to incorporate computers into their current curriculum. It also examines computer use to enhance students' understanding of science and mathematical concepts.

Understanding Vs. Knowing, John R. Stiles

Iowa Science Teachers Journal

How well do students understand concepts in science? Are teachers evaluating what students actually comprehend or merely how well they can recite information? How valuable are tests? What do they actually measure? How appropriate are the lessons to the children's developmental levels?

These and similar questions should be an important part of every teacher's evaluation procedure. We need to stop and ask ourselves such questions as: Why do I want my students to know this? Will knowing this make a difference in their lives? Is it important? Do the students really understand this? How can I be sure? From here, …

Measurement In Elementary Science, Barbara A. Bonnett

Iowa Science Teachers Journal

Ten year olds have great difficulty drawing the human face and form in proportion. To see if that skill could be enhanced, our fifth grade class set out to explore human proportion and measurements using metric rulers, meter sticks, graph paper and helpful partners.

An Analysis Of Physical Science Textbooks For Scientific Literacy, Hussein A. Baarah, Trudi L. Volk

Iowa Science Teachers Journal

Developing the scientifically literate individual is considered to be an important objective of science education in the United States (Blough and Schwartz 1990, Maarschalk 1988, Murane and Raizen 1988, National Science Teachers Association 1971, 1982; and Simpson and Anderson 1981). The scientifically literate person understands how science, technology and society influence one another, and is able to use this knowledge in everyday decision making (AAAS 1989, Yager and Harms 1981).

Editor's Corner - Editorial Privileges, Carl W. Bollwinkel

Iowa Science Teachers Journal

The editorship of the Iowa Science Teachers Journal has brought many privileges to this editor. Perhaps the greatest of these is the responsibility of determining what is most helpful for Journal readers and authors-those who establish the standards of science education in Iowa. This has not been an easy task and has often led to disagreement. This disagreement has been the basis of professional growth for writers, readers and editors-especially this editor. It is truly a privilege to maintain standards of quality.

Science Notes - Aviation/Aerospace Teacher Institute

Iowa Science Teachers Journal

Teachers are invited to participate in the Science Center of Iowa's Aviation/ Aerospace Teacher Institute which will be held from 8 a.m. to 5 p.m., July 11-15, 1994. Teachers will receive classroom materials and training in a number of space-related activities. Activities will include simulating an aerospace flight and the design of the first Martian city.

Science Notes - Ice Cream: An Edible Experiment In Thermodynamics

Iowa Science Teachers Journal

Ice keeps things cold because it absorbs energy from its surroundings, melting as it does so. The temperature at which a solid melts, called its melting point, is the same temperature at which the liquid form freezes. For pure water, this is 0° or 32° F. However, if some other substance, such as salt, is added to the water or ice, the freezing/melting point temperature is lowered. Thus, you can use salted ice to freeze liquid water.
