摘要:AbstractThe purpose of this study was to investigate the effects of multimedia simulation presentation developed in two different modes - Multiple Simulation Presentation (MSP) and Single Simulation Presentation (SSP) on the achievement of students with different levels of anxiety in the learning of Probability. The mathematical topic on “Probability” is considered to be abstract and difficult for students to understand and apply. The findings of this study showed that students using the SSP mode achieved significantly higher achievement than students using the MSP mode. The high anxiety students using the SSP mode achieved significantly higher achievement as compared to the high anxiety students using the MSP mode. This study concludes that the SSP mode is more effective for the learning of probability, especially for students with high anxiety level. From a cognitivist view point, this paper will discuss the effects of cognitive overloads on the information processing capacity of students with differing anxiety levels.
