Screencasting, or digital recordings of computer screen outputs, can be used to promote pedagogical transformation in the mathematics classroom by moving explicit, procedural-based instruction to the online environment, thus freeing classroom time for more student-centered investigations, problem solving, communication, and collaboration. This…

The aim of the study was to assess the medical teachers' preference for various lecture delivery methods like the lectures using chalkboard, utilizing transparencies with an overhead projector (OHP) or lectures using a PowerPoint presentation and their frequency of use of teaching aids. The faculty of the medical college was asked to fill in the…

Effective teaching in schools requires flexibility, energy and commitment. Successful teaching also requires that teachers are able to address learner's needs and understand the variations in learner's styles and approaches. Teachers can accomplish these requirements while creating an optimal teaching-learning environment by utilizing a variety of…

Educators are increasingly using educational technologies at the postsecondary level although little research has investigated the effects of such technologies on learning. Our research explored the effects of traditional lecture, slide-show-supplemented lecture, and virtual learning environment (VLE) on learning and frustration among college…

The Physical Chemistry in Practice (PCIP) DVD contains video programs (modules) and experimental data that present the research of scientists working in applications of physical chemistry. The DVD allows students to learn about cutting edge research in physical chemistry while making connections to the theoretical concepts learned in lecture.…

Two university professors offer advice, based on their experiences, for using a variety of forms of visual displays to enhance lectures. (LS)

Evidence suggests that a well-developed lecture script on a topic in medical biochemistry can quickly and easily be converted into an effective slide-tape program that is as educationally effective and well-received as one that is painstakingly tailored to the nature of the medium. (LBH)

An audio-visual course in Russian culture is given at Northern Illinois University. A collection of 4-5,000 color slides is the basis for the course, with lectures focussed on literature, philosophy, religion, politics, art and crafts. Acquisition, classification, storage and presentation of slides, and organization of lectures are discussed. (CHK)

Reports a study comparing an audio-tutorial instructional technique with the traditional lecture-laboratory type instruction. (SB)

A teaching technique where the lecture is interspersed with a series of multiple-choice questions displayed on 35mm slides or transparencies that can be projected by the overhead projector is described. The lecture progresses by projection and full discussion of each question. Layout of a typical question is appended. (MLW)

Describes a computer system (SPECIAL) that allows for the capture and playback of audio and slides from a lecture. SPECIAL provides random access to both audio and slides, and variable speed control of audio. Testing shows that learners prefer using faster speeds and that grades are higher for participants using this system rather than a textbook…

We investigated whether students liked and learned more from PowerPoint presentations than from overhead transparencies. Students were exposed to lectures supported by transparencies and two different types of PowerPoint presentations. At the end of the semester, students preferred PowerPoint presentations but this preference was not found on…
