This study compares the use of form and function analogy object boxes to more traditional lecture and worksheet instruction during a 10th-grade unit on human body systems. The study was conducted with two classes (N = 32) of mixed ability students at a high-needs rural high school in central New York State. The study used a pretest/posttest…

Laboratory demonstration, as well as biochemistry lecture, has been used to complement explanation of biochemical processes. The laboratory demonstration is very useful in teaching biochemistry to students who lack background in biology. The experimental model of fibrinolysis described here presents a complex biological reaction in simplified…

Introductory biology courses for pre-professional majors at large universities are usually high-enrollment lectures with associated labs that complement the lecture, but are independently taught and administered. Although web-based instructional formats have become popular alternatives to traditional lectures, it is unknown how these formats…

This hearing discussed how lack of coordination between laboratory exercises and classroom lectures, inadequately trained teachers, languishing facilities, and current high school organization diminish the value these exercises can have or prohibit them all together, and highlighted how a strong hands-on experience can create scientifically…

A study was conducted to compare the effectiveness of using the television lecture series "Introducing Biology" to traditional lecture techniques in a college-level Animal Biology course. The interest levels and subject course mastery of three groups of students were compared: (1) a control group who attended two 50-minute lectures per week; (2)…

This guide for teachers considering using independent learning describes the Keller Plan and describes ways in which it has been adapted for use in a variety of school situations. A discussion of the Keller Plan and its original formulation is followed by six case studies written by teachers in schools and colleges describing their use of the…

Reports a classification of expository teaching styles of biology, chemistry and integrated science teachers in Nigeria. No evidence was found of pupil-pupil interaction in any of the lessons observed. Compares results with other studies from Britain, Canada, and Indonesia and indicates significant differences. (CW)

Discusses how "live" experiments were combined with media packages and recorded lectures to allow coverage of more material and foster greater student/teacher interactions. Notes were distributed at the beginning of the semester which allow students to record experimental data from class demonstrations. Problems and suggestions for course…

Presents findings from research studies which suggest that changes in teaching procedures can increase survival rates in chemistry. Using 2-minute pauses in lecture and 3-second wait times in discussions, learning chemistry in context of major from which student comes, and computer applications are recommended. (JN)

Self-paced and lecture versions of a general geology course were taught by the same instructor using identical exams and nearly identical instructional materials. No significant differences were found in apparent scholastic abilities, exam results, or levels of satisfaction with the course. Enrollment was notably higher in the lecture version.…

Describes a method for students to evaluate and experience a repetition of important physics concepts during regular lecture sessions. The major goal was to train students to focus attention on course materials. (SK)

Critiques the use of computer-generated graphics and text in place of overhead projector transparencies in large lecture halls. Describes an experience in such a situation and suggests that colleagues can be helpful in assessing the effectiveness of educational innovations. (DDR)

Briefly discusses the failure of the lecture method when used alone in general chemistry. Describes the operational details of a modified team learning procedure and reports the results obtained using this experimental method. (DDR)

Reports on a study of the influence of different approaches to teaching units from the Jordanian science curriculum on over 600 students from grades 6, 9, and 10. Trains a small sample of male and female teachers in the use of cooperative learning and lecture-demonstration approaches to teaching. (Contains 17 references.) (Author/YDS)

The increased availability of computational modeling software has created opportunities for students to engage in scientific inquiry through constructing computer-based models of scientific phenomena. However, despite the growing trend of integrating technology into science curricula, educators need to understand what aspects of these technologies…
