The present study explores ways to enhance students' question-asking ability (i.e., the ability to ask critical questions), which is the premise of scientific inquiry and a precondition for effective science teaching. A survey of junior high school students in Zhejiang province in China showed that students' questioning behavior was not well…

Inquiry is essentially a process in which research questions are asked and an attempt is made to find the answers. However, the formulation of operational research questions of the sort used in authentic scientific inquiry is not a trivial task. Here, we set out to explore the possible influence of separating the research question from the…

This study explores questioning practices adopted by elementary teachers while facilitating science inquiry discussions prior and subsequent to their participation in a summer institute in which they were provided with scholarly descriptions of inquiry-based teacher questioning (i.e., typologies of questions used by discourse analysts to…

The purpose of this study was to find out how teachers use questions in classroom discourse to scaffold student thinking and help students construct scientific knowledge. The study was conducted in large-class settings where the medium of instruction was English although the students were non-native speakers of the language. Six teachers teaching…

Determined the effects of questions on the learning of 55 undergraduate education majors from case exhibits associated with a "walk-through" museum exhibit. The case exhibits contained diagrams, some specimens, a large amount of written material, but no questions. Also compared the effects of experimenter generated questions versus…

To enhance the learning outcomes achieved by students, learners undertook a computer-simulated activity based on an acid-base titration prior to a university-level chemistry laboratory activity. Students were categorized with respect to their attitudes toward learning. During the laboratory exercise, questions that students asked their assistant…

This project consisted of a meta-analysis of U.S. research published from 1980 to 2004 on the effect of specific science teaching strategies on student achievement. The six phases of the project included study acquisition, study coding, determination of intercoder objectivity, establishing criteria for inclusion of studies, computation of effect…

Reports a qualitative analysis of classroom discourse in which use of questions by science teachers is assessed in terms of arguments to establish scientific knowledge claims. Questions are analyzed not for form/frequency but for their function in developing arguments that establish claims rationally. (Author/JN)

Investigated the effects of variation in teacher wait-time on science achievement for students (N=733) in 11 Australian middle schools. Conclusions provide evidence that the extension of teacher wait-time produces desirable changes in achievement. (CS)

Determined if student questioning skills could be taught within framework of an ongoing chemistry course and if acquisition of these skills depends on high school students' (N=108) level of intellectual development. Results indicate that questioning skills can be acquired by students, regardless of their level of Piagetian intellectual…

In a large introductory physics course, structured weekly journals (weekly reports) regularly encouraged students to ask questions about the material. The resulting questions were collected for one quarter and coded based on difficulty and topic. Students also took several conceptual tests during the quarter. The reports contained more questions…

Six biology teachers and 90 students participated in this study. Results indicate that teachers can be trained to use a systematic questioning technique, trained teachers can employ the technique in classroom settings, and students taught by the technique achieve higher and retain knowledge longer than those in control groups. (JN)

Reports on a study which investigated the effects of varying percentages of high cognitive questions on primary and intermediate students' achievement at the knowledge, comprehension, and analysis levels. Also investigated the effects of redirecting questions on student achievement. (CS)

Reports a study that examined the generalizability of selective-attention and academic-studying hypotheses to a modified science chart medium. The adjunct questions used in this study were designed to selectively focus students' attention on specific columns in a modified science chart, with the goal of improving student achievement on a test…

Results of 11 studies of classroom practices used with activity-based elementary science programs were combined quantitatively using a composite category system. One finding reported is that teachers trained in program use spent less time talking and more on activities than untrained teachers using the programs. (Author/JM)
