摘要编制了中学生微机信念量表（MBI），并对其进行了验证。本研究以269名六、七、八年级学生为样本，进行项目分析、量表信度评估及量表完整性因素分析。这两个规模进行了良好的可靠性（自我效能α = 0.90和预期结果α = 0.85），因子分析清楚地表明了测量的结构的独特性。两个量表的结构效度的初步证据清楚地证明了他们的可预测的协方差与变量，如对计算机的态度，对科学的态度，对计算机学习的兴趣，对科学学习的兴趣，对计算机学习的期望。t检验揭示了量表和家庭内计算机访问之间的密切关系。MBI似乎准备在未来的研究工作中使用。
AbstractThe Microcomputer Beliefs Inventory (MBI) was developed and validated to measure the self-efficacy and outcome expectancy beliefs of middle school students toward computers. Item analysis, scale reliability assessment, and factor analysis of scale integrity were conducted upon a sample of 269 sixth-, seventh-, and eighth-grade students. Both scales performed with good reliability (Self-efficacy alpha = 0.90 and Outcome expectancy alpha = 0.85), and factor analysis clearly demonstrated the distinctiveness of the constructs measured. Preliminary evidence of the construct validity of both scales was clearly demonstrated by their predictable covariance with variables such as attitude toward computer, attitude toward science, interest in computer learning, interest in science learning, and expectations for computer learning. A strong relationship between the scales and computer access within the home was revealed by the t-tests. The MBI appears ready to be utilized in future research efforts.
