Presents a logically consistent framework for teaching introductory biology beginning with simple facts and progressing rapidly to sophisticated conclusions and questions. (JRH)

Reports survey results of 126 students enrolled in first- or second-year biology courses concerning the effectiveness of different teaching methods within the lecture format. Indicates that the traditional, didactic lecture, although perceived as least effective, was regarded as highly effective when enhanced by active student involvement.…

The high points of the story of RNA are presented. The functions of RNA within the cell, how these functions are carried out, and how they evolved are described. The topics of splicing, self-splicing, RNA editing, transcription and translation, and antisense RNA are discussed. (KR)

Examines two instructional strategies, the traditional and learning cycle approaches, and compares them with regard to the variables of sequence, format, and necessity. Concludes that students exposed to the laboratory and discussion type had higher test scores than those in the lecture or reading groups. (Author/RT)

This document introduces fifth-grade children to the microscopic world, to the instruments needed to make it accessible, and to the appearance and structure of cells in nonliving as well as living things. Aims of the unit include providing children with an instrument which extends their senses in a radical manner, and leading them in using this…

A teacher had to deal with the problem of effectively instructing slow learners while making sure that the gifted students were kept interested by practicing creative thinking. Paradox and analog techniques were applied to instruction in a biology class. (SBH)

Shares excellent quotes that can be used in the classroom to enliven or punctuate a topic of discussion. (ZWH)

Describes a strategy to make chi-square calculations and interpretations more understandable by presenting the theory behind the test to the students in a visual manner. Involves using dihybrid corn to generate a large sample of chi-squares followed by plotting a frequency distribution to get at the meaning behind the chi-square table. (JRH)

Describes a course entitled "DNA and Evolution" in which students develop an appreciation for what science is and how it is practiced as well as an understanding of how some of the most central ideas in biology were developed and tested. Discusses the design of the course, the lecture and discussion topics, and the results and their…

This document features a lesson plan in which students work in teams to act out different ecosystem services, describe several free services that biodiversity provides to human, and explain how these services make life on earth possible. Samples of instruction and assessment are included. (KHR)

Links between science and literature brought about by authors interested in nature are discussed. Examples of literature which incorporate ideas of science are described. The enrichment of a student's appreciation of biology by incorporating literature into the curriculum is emphasized. (23 references) (KR)

Describes an innovative model for improving the teaching of evolution in high school biology courses. Combines the teaching of evolution with both a modern view of the nature of science and the use of humans as the primary case study for understanding evolutionary concepts. Requires consistent use of student-centered activities. Contains 20…

This six-chapter guide is designed to help Georgia teachers adopt or adapt various options into the local school's science curriculum. Major areas addressed in the chapters are: (1) secondary school curriculum development (focusing on performance objectives, sequencing the curriculum, evaluation, and scientific literacy); (2) teaching methods…

The use of invertebrates as classroom "pets" can develop students' skills in scientific inquiry and instill respect for science. Few materials are needed for projects involving invertebrates. Suggested activities using snails, crickets, earthworms, crayfish, and guppies are offered. (DF)

Describes a laboratory exercise requiring students to separate a selected number of organisms into groups of increasing similarity and to relate these groups directly to the kingdom-species system of classification. (Author/MA)
