The current study describes preschool teacher-child interactions during several commonly scheduled classroom activities in which teachers deliver instructions. An observation system was developed that incorporated measurement of evidence-based compliance strategies and included the types of instructions delivered (e.g., integral or deficient directives, embedded directives, "do" or "don't" commands), the children's behavior with respect to the instructions (e.g., compliance, noncompliance, active avoidance, problem behavior), and the differential responses of the teacher to the child's behavior following an instruction (e.g., appropriate or inappropriate provision of attention and escape). After 4 classroom teachers were observed at least five times in each of five target activities, simple and conditional probabilities were calculated. Results indicated that (a) the frequency of instruction and probability of compliance varied as a function of activity type, (b) "do" commands and directive prompts were delivered almost to the exclusion of "don't" commands and nondirective prompts, (c) the likelihood of compliance was highest following an embedded or an integral directive prompt, and (d) although putative social reinforcers were more likely to follow noncompliance than compliance and were highly likely following problem behavior, compliance occurred over twice as much as noncompliance, and problem behavior during instructions was very low. Implications for using descriptive assessments for understanding and improving teacher-child interactions in the preschool classroom are discussed.
本研究描述了在教师进行指导的几种常规课堂活动中,学前教师与儿童之间的互动情况。开发了一种观察系统,该系统纳入了基于证据的依从策略的测量,并包括所传达指导的类型(例如,完整或不完整指令、嵌入式指令、“做”或“不做”命令)、儿童针对指令的行为(例如,依从、不依从、主动回避、问题行为),以及教师在指令发出后对儿童行为的不同反应(例如,给予关注和逃避的恰当或不恰当方式)。在对4名课堂教师在五项目标活动中的每一项至少进行了5次观察之后,计算了简单概率和条件概率。结果表明:(a)指导的频率和依从概率随活动类型而变化;(b)几乎只发出“做”命令和指令性提示,而不发出“不做”命令和非指令性提示;(c)在嵌入式或完整指令提示之后,依从的可能性最高;(d)虽然假定的社会强化物在不依从之后比在依从之后更有可能出现,并且在问题行为之后出现的可能性很高,但依从发生的次数是不依从的两倍多,并且指令期间的问题行为非常少。文中讨论了使用描述性评估来理解和改善学前课堂中教师与儿童互动的意义。
