Early childhood teachers' computer attitudes, knowledge, and practices

Two hundred-fifty kindergarten and preschool teachers in public and private schools in a five county area of Illinois, including the city of Chicago, were surveyed to identify teachers' computer attitudes, knowledge and practices. The results showed that over ninety percent of the teachers had positive or very positive personal and professional attitudes towards using the computer. Fifty-one percent of the teachers were using the computer in their classroom. Of that fifty-one percent, twenty percent said that their children also used the computer in a lab in the school, while thirty one percent only had the computer in their classroom. An additional twenty percent did not have a computer in the classroom, but did have a computer lab available. Twenty-nine percent did not have a computer in the lab or in the classroom. Thirty six percent of the teachers had a computer at home with the most common brand being some type of Apple computer. Seven percent of the teachers had no training, knowledge or experience on the computer. Sixty-seven percent had some training, knowledge and experience with a computer and twenty six percent had training and knowledge and used the computer frequently. The majority of teachers had learned to use a computer through workshops, university classes or on their own. Very few teachers had received instruction at school from a school computer instructor.

Young Children's Interaction With a Microcomputer

While research on the effects of computers in classrooms and the effects of teaching computer languages is burgeoning, the question of how children interact “naturally” with a computer has not been researched. In order to observe children's interaction with a computer, an Apple II was placed in a university laboratory school classroom. Thirty-nine children were allowed free access to the computer during center time and detailed observational logs were kept of the children's interaction with the computer. It was determined from this base study that computer play for young children is an initial step in computer literacy.

Computer ergonomics: the medical practice guide to developing good computer habits

Medical practice employees are likely to use computers for at least some of their work. Some sit several hours each day at computer workstations. Therefore, it is important that members of your medical practice team develop good computer work habits and that they know how to align equipment, furniture, and their bodies to prevent strain, stress, and computer-related injuries. This article delves into the field of computer ergonomics-the design of computer workstations and work habits to reduce user fatigue, discomfort, and injury. It describes practical strategies medical practice employees can use to improve their computer work habits. Specifically, this article describes the proper use of the computer workstation chair, the ideal placement of the computer monitor and keyboard, and the best lighting for computer work areas and tasks. Moreover, this article includes computer ergonomic guidelines especially for bifocal and progressive lens wearers and offers 10 tips for proper mousing. Ergonomically correct posture, movements, positioning, and equipment are all described in detail to enable the frequent computer user in your medical practice to remain healthy, pain-free, and productive.
