Abstract:Providing feedback to preservice teachers about their teaching style is an important component of most performance-based teacher education models. In these models it is assumed that if preservice teachers are provided a critique of their ability to perform a certain teaching behavior in a specific microteaching setting, then the teachers will be able to improve their ability to perform that behavior in subsequent teaching assignments. Interest has been shown by a number of researchers about whether the source … Show more
“…As feedback was not provided to students, wait-time I was probably reduced by student talk. Esquivel et al (1978) reported that feedback on wait-time II did not lead to increased wait-time over a sequence of three science lessons. The results of a pilot study conducted by Swift!…”

IntroductionAn understanding of classroom learning requires careful analyses of the variables that constitute the learning environment. Among those that are most likely to influence learning are teacher and pupil discourse since verbal interaction is the principle mode of communication in most classrooms. For example, through the use of appropriate questions, teachers can provide pupils with a cognitive focus on the instructional objectives. Similarly, a clear explanation in response to a pupil question can clarify misunderstandings that might otherwise inhibit learning. Thus, the quality of the verbal interaction may directly affect the amount of learning that occurs. Although much of the research on verbal interaction has dealt with aspects of teacher questioning, the results have tended to be inconsistent (cf. Winne 1979). In contrast, a variable called wait-time, which is related to the duration of certain pauses between speakers, has been shown to have a consistent effect on the quality of verbal interaction in classrooms.If teacher discourse is to influence pupil learning, the information contained in the discourse must be cognitively processed by the learner. As a consequence, the rate at which information is presented should be matched with the cognitive processing capabilities of pupils. Cognitive processing of data is likely to be dependent on learner attributes such as cognitive aptitude and motivation state, as well as characteristics of the discourse. For example, processing time for cognitively complex discourse is expected to be greater than the time required to process less complex verbal information. Thus, as teachers provide pupils with information or provide a cognitive focus through soliciting, adequate time should be provided for all pupils to engage in an appropriate manner. To ensure that adequate time is provided, teachers should pause after solicitations or at regular intervals during explanations.The pause following pupil discourse is also of potential importance. As Rowe (1974 a) noted, speech is interspersed with pauses which range from quite short time intervals separating individual words to much longer intervals which occur as a speaker completes a segment of speech and pauses to consider what to say next. These time intervals often exceed three to five seconds. Siegman and Pope (1965) reported that the length of pauses in discourse increased in proportion to the difficulty of the task, whilst

“…Although the body of research on in-service education and teacher change is quite large, there appears to be a scarcity of research that deals specifically with science teacher education programs (Evans, 1987). A number of studies present evidence that training that involves a questioning classification or strategy analysis system can be instrumental in changing the behavior of preservice teachers (Esquivel, Lashier, & Smith, 1978;Riley, 1978;Tobin, 1985;Yeany, 1977). In-sentice training in specific behaviors such as questioning (Bruce, 1971;Otto & Schuck, 1983) and wait time (Chewprecha, Gardner, & Sapianchai, 1980;Swift & Gooding, 1983) can also be effective in changing teacher behaviors.…”
This study examines the effect of an in‐service education program emphasizing problem solving on teacher attitudes toward teaching science and on teaching behaviors. Twenty‐two middle school science teachers participated in the program and another 22 served as the control group. The two groups were similar in terms of gender, teaching status, educational background, and professional activity during the treatment period. Before and after the eight‐month project, subjects completed attitude surveys and recorded videotapes of themselves teaching science lessons. No difference was noted between the groups on the attitude measure. The videotapes were analyzed using a coding scheme developed for use in this study. A multivariate analysis of variance performed on the observational data showed a significant difference between the groups on the postworkshop measure. The experimental‐group teachers shifted to more student‐centered classrooms, with less lecture and procedural talk. This study provides evidence that an extended in‐service education program can affect the teaching behaviors of science teachers in the middle grades.
