高中生化学问题解决思维过程口语报告编码分析

将高中生化学问题解决思维过程口语报告分为相应的10个行为指标进行人工编码和定量分析。被试是56名高中生,材料为6个中等难度的化学问题,通过“出声思考”实验,记录口语报告,并对口语报告进行编码和数据统计分析,结果发现:(1)高中优生的重复、解释、推理、归纳、总结等行为指标上明显优于中等生;(2)在解决不同类型的化学问题时,重复、设问、推理、归纳和反思等指标存在明显差异;(3)学生能力层次与问题类别在重复、推理、归纳和试误等行为指标上存在明显交互作用。

An Analysis of Verbal Records as Coding Data in the Process of Chemistry Problem-solving

Manually coded and quantificationally analyzed were 10 behavior codes consistent with the verbal record of senior middle school students in the process of chemistry problem-solving.The subjects were 56 students.The materials were 6 middle-difficulty chemistry problems.Through phonation-thinking,verbal record-coding and datum-analyzing,we obtained the results as follows:(1) the good-learning students did better than the poor-learning ones in repetition,explanation,inference,conclusion and summarization;(2)In their solving different chemistry problems,there were obvious differences in repetition,inference,conclusion, reflection;(3) There was obvious interaction between ability levels and problem sorts in repetition,inference,concludsion and attempt to get solution.
