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…

Two postlaboratory discussion strategies (Probing and Nonprobing) were tested for effectiveness on learning science concepts by sixth graders. Similar laboratory experiences were provided to all, but discussion strategies differed. Analysis indicated significantly higher mean gain scores for the Nonprobing strategy group. (PS)

Describes a case study of an expert teacher's questioning strategies during an open-inquiry engineering curriculum in a grade four and five classroom. Analysis provides evidence for the complexity of questioning that is characterized by the interactions of context and content of, and response and reactions to, questions. Contains 45 references.…

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)

Elementary school science students taught by preservice teachers trained to ask observation and classification questions were administered an attitude measure. Results showed a significant difference only on a frustration measure, with the experimental group exhibiting more frustration than a control group. (MLH)

Explores the differences between deep and surface approaches to learning science. Findings indicate that the deep-surface learning differences fall into five categories: (1) generative thinking; (2) nature of explanations; (3) asking questions; (4) metacognitive activity; and (5) approach to tasks. Suggests that teachers can encourage a deep…

Investigates the consequences of inquiry and didactic teaching when students either cooperate or compete with each other on (a) students' acceptance of the teaching method, (b) their approval of the teacher, (c) their experience of peer support, and (d) their beliefs that they have learned. Eighty fourth and fifth grade students were randomly…

Investigates the wait-time after each question, the number of questions asked per minute, and the cognitive levels of questions asked by 10 preservice teachers. After initial data collection to determine subjects question-asking practices, one-half of the sample underwent instruction to change their question-asking practices. Results revealed the…

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…

Compares frequencies and styles of questioning strategies used in Modern Biology and Biological Science Curriculum Study--BSCS Green, BSCS Yellow and BSCS Blue secondary school biology textbooks. Findings revealed significant differences between textbooks in terms of number and type of questions used. (CP)

The two-phase study was designed to (1) create a means whereby preservice teachers could lengthen the time they allow for a student to respond after posing a question; and (2) to study the relationship of want-time as an independent variable and dialogue measure, as a dependent variable. (RE)

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…
