摘　　要：传统的测量模型有一重要假设,即被试在完成测验过程中自始至终采用同一种策略.事实上,被试会根据题目类型不同而改变其解题策略,称之为策略转换.使用策略转换模型和潜在类别分析两种方法对平衡秤任务测验作答过程中的策略转换现象进行了分析比较.结果显示:策略转换模型存在策略位置参数越界、顺序混乱等缺陷,不适于策略转换问题研究;使用潜在类别分析方法可有效分析被试的策略转换行为,儿童在完成平衡秤任务测验时呈现出不同的策略转换路径.Flexibility of strategy use in problem solving is one important feature of higher cognitive functioning. One implicit assumption in previous research on rules used in balance scale task is that children use the same strategy or rule throughout the test. That＇s not true and the children may shift their strategies when faced with different tasks. Strategy Shift Model has been proposed for that specific situation. In the present study, one alternative approach based on latent class analysis is compared with Strategy Shift Model through the analysis of balance scale task. A test made of 20 items which belong to four different type of balance scale task, was developed for the present research. It is shown that latent class analysis can be an effective method for research on strategy shift and produce the strategy shift path diagram. As the path diagram indicates, children may follow different lines of strategy shift and differs with the results under general strategy assumption. Finally, the limitations of the present study and future directions of research on strategy shifts are discussed.
