Heard but not seen: Instructor-led video and its effect on learning.

Educators and instructional designers are seeking ways to increase levels of learning. One of the ways this is being done is through cognitive load theory which attempts to reduce cognitive load through a better understanding of working memory and the factors that impact its function. Past studies have found that working memory processes visual and auditory information using separate and non-sharable resources (dual coding theory) and that by properly utilizing multimedia elements, information processing in working memory is more efficient (multimedia learning). What is not known is the effect that instructor-led video, which uses the visual channel but delivers no information, has on the cognitive load of the learner. Further, will the introduction of multimedia elements make the information processing of the learner more efficient? This study examined three ways in which instructional designers may create a more efficient learning environment through a better understanding of multimedia learning. First, by using the theories of multimedia learning, I examined a more efficient use of sensory memory. By minimizing extraneous load, which communication theory calls noise, on working memory through increased utilization of the visual and auditory channels, the effectiveness of instruction was increased. Secondly, the multimedia effect, defined as using visual …

The relationship between computer use and academic achievements. (open access)

The relationship between computer use and academic achievements.

Computer technology has been used in education for years, and the government budgets large amounts of money to foster technology. However, it is still a debated whether computer technology makes a difference in students' learning outcomes. The purpose of this study is to find if any relationship exists between computer use by teachers and students and the students' academic achievement in math and reading for both traditional populations and English language learner (ELL) tenth graders. Computer use in this study included the computer activities by students and teachers, in terms of the time, frequency, activities types, the places students use computers, teachers' computer activities, and the training teachers received. This study used data gathered from tenth grade students from the dataset Education Longitudinal Study of 2002 (ELS:2002) of the National Center for Education Statistics (NCES). Fifteen thousand, three hundred and sixty-two students were randomly selected to represent all U.S. tenth-graders attending schools in 2002. The findings showed diverse relationships consistent with the literature. Based on the findings, some suggestions were made to teachers and parents about the quality of school work and computer use by students and teachers.

Using SERVQUAL to Measure Users' Satisfaction of Computer Support in Higher Educational Environments (open access)

Using SERVQUAL to Measure Users' Satisfaction of Computer Support in Higher Educational Environments

The purpose of this research was to measure users' satisfaction with computer support in the higher education environment. The data for this study were gathered over a 5-week period using an online survey. Subjects (N=180) were members of a college at a major Texas university, which included both faculty and staff. SERVQUAL was the instrument used in this study. Two-ways statistical ANOVA analyses were conducted and revealed three statistically significant differences for Gender, Classification, and Comfort Level.

Relationships between perceptions of personal ownership of laptop computers and attitudes toward school. (open access)

Relationships between perceptions of personal ownership of laptop computers and attitudes toward school.

The feeling of ownership is a topic of research that has not been addressed as a component in the integration of technology in the K-12 classroom. The effectiveness of this abstract concept in relationship to digital computing is important in the evaluation of one-to-one initiatives in education. This paper reports findings of a research study conducted using a new ownership survey instrument I developed, the Laptop Usage Inventory (LUI). Also administered during the study was the Student Attitude Survey given in a pretest/posttest design. The instruments were administered to seventh and eighth grade students in a north Texas middle school in the 2007-2008 school year. The methodology used to evaluate the Laptop Usage Inventory consisted of Cronbach's alpha and various scaling methods. LUI scale scores were correlated with the results of the Student Attitude Survey to compare students' attitudes toward school before and after using a laptop computer for the school year. Implications for laptop initiatives and for the classroom are discussed and a future research agenda is presented.
