Educational software usability: Artifact or Design?

Online educational technologies and e‐learning tools are providing new opportunities for students to learn worldwide, and they continue to play an important role in anatomical sciences education. Yet, as we shift to teaching online, particularly within the anatomical sciences, it has become apparent that e‐learning tool success is based on more than just user satisfaction and preliminary learning outcomes—rather it is a multidimensional construct that should be addressed from an integrated perspective. The efficiency, effectiveness and satisfaction with which a user can navigate an e‐learning tool is known as usability, and represents a construct which we propose can be used to quantitatively evaluate e‐learning tool success. To assess the usability of an e‐learning tool, usability testing should be employed during the design and development phases (i.e., prior to its release to users) as well as during its delivery (i.e., following its release to users). However, both the commercial educational software industry and individual academic developers in the anatomical sciences have overlooked the added value of additional usability testing. Reducing learner frustration and anxiety during e‐learning tool use is essential in ensuring e‐learning tool success, and will require a commitment on the part of the developers to engage in usability testing during all stages of an e‐learning tool's life cycle.

基于多项式数字基带自适应预失真技术的研究

由于自适应数字预失真具有稳定性好、适应能力强等优点,被广泛应用于实现功率放大器的线性化。而本文正是研究了基于多项式数字基带自适应预失真技术。首先,介绍了基于多项式数字基带自适应预失真技术;其次,分析了间接学习结构理论;最后,对OFDM信号进行了仿真实验。结果表明：预失真可以有效地抑制带外频谱以及补偿功放的非线性失真和记忆效应。     

In Search of Quality in Finnish Pre‐School Education

This study was conducted during the academic year 2002–2003 in a municipality in Eastern Finland. It focuses on pre‐school education assessing its quality factors from the parents’, teachers’ and children’s points of view. Theoretically, the study focuses on analyses of the purposes of the national core curriculum and pedagogical issues that are related to understanding quality in pre‐school education. According to this study, parents, pre‐school teachers, and children are satisfied with pre‐school education in general. They all emphasize its importance for children’s development in the areas of cognitive and social skills and development. Results clearly show that pre‐school education should be revised to meet the needs of improvement in the area of co‐operation, the expectations of modern society, and the aims of the national curriculum. In addition, pre‐school education is still searching for its own cultural position in the area of Finnish school and daycare systems.     

郭沫若在先秦史研究中使用的科学方法管窥

郭沫若是中国现代杰出的历史学家、考古学家、古文字学家、作家和诗人 ,他在先秦史研究中取得了前人无法与之相比的成就。这是因为他是把马克思主义的辩证唯物主义和历史唯物主义作为世界观和方法论来研究先秦史的第一个典范。同时 ,他还继承和发展了前人研究历史的许多科学方法 ,诸如乾嘉学派的归纳法、古史辨派的层次性归纳法、乾嘉学派和今文学派都曾使用过的内外线结合法以及王国维的二重证据法。为了有助于史学研究方面的继承和创新 ,今天探讨郭沫若在先秦史研究中使用的科学方法也是十分必要的
