Although the practice of giving examples is central to the effective teaching and learning of science, it has been the object of little educational research. The present study attends to this issue by systematically examining the exemplification practices of a university professor and his students' learning experiences during a biology lecture on…

Professional development becomes relevant and effective when teachers are actively involved, collaborate, and when it is linked to teachers' daily school practice (Hunzicker in "Prof Dev Educ" 37:177-179, 2011). Preparation of teachers for a curriculum implementation such as the new subject Nature, Life, and Technology can be done…

Introductory biology courses form a cornerstone of undergraduate instruction. However, the predominantly used lecture approach fails to produce higher-order biology learning. Research shows that active learning strategies can increase student learning, yet few biology instructors use all identified active learning strategies. In this paper, we…

Learning takes place mostly through communication. This is why teachers employ different types of interaction in the classroom in order to provide a varied environment for the students. Apart from the commonly used Student-Teacher-Talk or Teacher-Student-Talk, presentations or lectures may offer advantages with regard to the promotion of…

The purpose of this quasi-experimental study was to examine attitude and achievement among fifth grade students participating in inquiry and lecture-based forms of instruction through interactive television. Participants (N = 260) were drawn from registered users of NASA's Digital Learning Network[TM]. The first three levels of Bloom's Revised…

Synchronous e-voting systems (commonly known as "clickers") have become increasingly popular as they can be used to enhance interactivity in lectures. Asynchronous electronic surveys (AESs), unlike these voting system, usually serve as a method of gathering feedback before or after teaching sessions. This paper describes and evaluates a project…

As an alternative to reading quizzes, a team of biochemistry instructors implemented student reading questions (Henderson and Rosenthal 2006) as a new instructional strategy within their large-enrollment biochemistry courses. Unexpected positive outcomes of this instructional method were realized, as well as limitations of the method within this…

This research concerns the development and assessment of a program of introductory astronomy conceptual exercises called ranking tasks. These exercises were designed based on results from science education research, learning theory, and classroom pilot studies. The investigation involved a single-group repeated measures experiment across eight key…

The increased use of instructional technology in the past decade has brought about many changes in college teaching, including changes in the lecture format. We surveyed students in six science courses to obtain their opinions regarding technology use, as well as non-technological instructional techniques, and the characteristics of outstanding…

Uses videotaped lectures and interviews to understand lectures in a physics course for prospective elementary teachers. Reports that the professor staged Aristotle, natural philosophy, and students' observations and intuitive knowledge in opposition to Galileo, controlled experiments, and mathematical inscriptions. Concludes that this form of…

Presents techniques aimed at promoting a higher level of student-faculty interaction and active student participation in the learning process in introductory physics lecture classes. Discusses group problem solving, the use of flash cards, and assessment. (JRH)

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)

Encourages teachers to convert current lecture materials into Web-ready formats and use these for in-classroom lecture presentations. Presents practical suggestions for developing multimedia classrooms and explores issues involved. (Author/JRH)

Compares the effectiveness of two instructional models in bringing about a valid understanding of science concepts in prospective elementary teachers. Describes the two instructional models; an expository model and a learning cycle model. Concludes that college students understandings of science concepts may be improved using a combination of the…

Reports on a study intended to compare the effects of two methods of instruction designed to teach preservice elementary teachers to acquire and retain integrated science process skills. Results indicated that the self-instructional method was significantly more effective than the teacher-directed method. (TW)
