摘要
科学假设检验思维是科学问题解决的核心,采用二维物理量与空间相互嵌套的杠杆平衡条件发现作业为真实问题情境,研究了小学六年级和初中二年级学生的科学假设检验思维。研究结果表明,启发式是学生进行科学假设检验思维的重要策略;真实问题情境和任务特点影响学生的反应倾向;初中二年级学生能够运用假设检验思维在一定程度上解决含有二维物理量的、熟悉的真实科学问题。
Scientific hypothesis-testing is the core of scientific problem-solving. Using balance＇ task which has two-dimension var iables nesting in spaces as its real-life problem situation, the study examines scientific hypothesis testing of children in grade 6 from a primary school and in grade 2 from a secondary school. The results show that heuristic strategy is important in scientific hypothesis-testing, real-life situation and characteristics of the task influence students＇ responses, and to some extent children in grade 2 of secondary schools are able to solve real scientific problems using hypothesis-testing.
