The audio-visual revolution: do we really need it?
Journal of Advanced Nursing
|March 1, 1979
Summary
The adoption of audio-visual technology in nursing education is driven by trends, not educational efficiency. Critical evaluation of educational media effectiveness is needed for responsible implementation.
Area of Science:
- Medical Education
- Educational Technology
- Nursing Education
Background:
- The nursing profession in the UK is experiencing a surge in audio-visual (AV) technology adoption.
- Nurse tutor courses now incorporate educational technology, and nursing schools are acquiring advanced electronic teaching aids.
- This integration occurs during a period of significant change and funding availability for AV equipment.
Purpose of the Study:
- To critically examine the effectiveness and rationale behind the use of AV aids in nursing education.
- To investigate the factors influencing the adoption and utilization of educational technology in nursing.
- To address the gap between the enthusiasm for AV technology and its proven educational efficiency.
Main Methods:
- An eclectic review of media research was conducted.
- The study examined widespread dissatisfaction among international educational technologists.
- Causative factors for the current state of AV technology adoption were identified from literature.
Main Results:
- The purchase and use of AV equipment are often based on personal preference or trends, rather than educational efficiency.
- Teachers often fail to ask critical questions about the necessity and effectiveness of AV aids.
- Research findings, particularly from educational television, highlight the complexities of media effectiveness.
Conclusions:
- Decisions regarding the use of educational media are more complex than initially perceived.
- A more responsible and critical approach to adopting AV technology in nursing education is advocated.
- Further research is needed to ensure AV aids enhance, rather than hinder, educational outcomes.

Hearing
When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.
Perception of Sound Waves
The human ear is not equally sensitive to all frequencies in the audible range. It may perceive sound waves with the same pressure but different frequencies as having different loudness. Moreover, the perception of sound waves depends on the health of an individual's ears, which decays with age. The health of one's ears may also be affected by regular exposure to loud noises.
The pitch of a sound depends on the frequency and the pressure amplitude of the source. Two sounds of the same frequency...

Auditory Pathway
Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.

Design Example
The innovation of touch-tone telephony revolutionized the telecommunications industry by replacing the traditional rotary dial with a dual-tone multi-frequency (DTMF) signaling system. This system uses a matrix-style keypad with buttons arranged in four rows and three columns, creating 12 distinct signals each assigned to a pair of frequencies. Each button press results in a simultaneous generation of two sinusoidal tones – one from a low-frequency group (697 to 941 Hz) and one from a...
Visual System
Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

Auditory Perception
The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the cochlea, a...
