Retrieval Practice Enhances Analogical Problem Solving

The impact of retrieval practice on analogical-problem-solving performance was investigated using a complex, educationally relevant task. Participants studied a statistical hypothesis testing scenario and practiced recalling the material or repeatedly studied it. Participants then completed a final test either 5 minutes or 1 week later involving a novel hypothesis-testing scenario that shared an intermediate procedural strategy and superficial and structural similarity with the study scenario but that differed at a specific procedure level. When the final test was given after 5 minutes, no differences in performance were observed across conditions (d = 0.01). Crucially, on the delayed test, retrieval practice produced superior performance than did repeated studying (d = 0.81), whereby participants were better at applying learned knowledge to solve a novel problem.     

Children’s solving of ‘Tower of Hanoi’ tasks: dynamic testing with the help of a robot

Abstract

The present study investigated the usefulness of a pre-programmed, teleoperated, socially assistive peer robot in dynamic testing of complex problem solving utilising the Tower of Hanoi. The robot, in a ‘Wizard of Oz’ setting, provided instructions and prompts during dynamic testing to children when they had to solve 3?D Tower of Hanoi puzzles. Participants were 37?second grade 8-year-old children, of whom half received graduated prompts training between pre-test and post-test, delivered by the robot, and half did not. It was found that children’s progression in task accuracy varied considerably, depending on whether or not children were trained in solving Tower puzzles. Trained children showed greater progression in the number of Tower problems that they could solve accurately, made considerably fewer steps, although the Tower puzzles increased quickly in difficulty level. The mean completion time of trained children decreased at a slower rate than that of the untrained children, but both groups of children took considerably more time to think and plan ahead before they started the solving process. Only moderate relations with planning behaviour were found. In general, the study revealed that computerised dynamic testing with a robot as assistant has much potential in unveiling children’s potential for learning and their ways of tackling complex problems. The advantages and challenges of using a robot in educational assessment were discussed.     

基于UML statecharts 测试方法的研究

Unified modeling language （UML） is a powerful graphical modeling language with intuitional meaning. It provides various diagrams to depict system characteristics and complex environment from different viewpoints and different application layers. UML-based software development and modeling environments have been widely accepted in industry, including areas in which safety is an important issue such as spaceflight, defense, automobile, etc. To ensure and improve software quality becomes a main concern in the field. As one of the key techniques for software quality, software testing can effectively detect system faults. UML based software testing based is an important research direction in software engineering. The key to software testing is the generation of test cases. This dissertation studies an approach to generating test cases from UML statecharts.

电液伺服材料试验机的动力学响应特性研究

对MTS810电液伺服材料试验机在位移控制和载荷控制两种控制方式下的动力学响应特性进行了研究。以岩石压缩测试数据为例,对载荷-时间曲线、位移-时间曲线进行了对比分析,发现岩石破坏过程中,位移控制方式下可以观察到岩石的局部损伤至破坏的演化过程,载荷在岩石破坏时刻突然降为0;而载荷控制方式下看不到损伤演化过程,载荷未突然降为0。说明试验机本身的结构响应会影响对试样力学性能的测试。
