This article relays results of a study focused on questions invoked to correct declarative knowledge deficits while readers process science texts explaining natural phenomena. Firstly, the authors focused on finding out what kind of questions are asked by students who read these texts and, secondly how task demand influences quantity and quality of formulated questions. Two hundred and eighty nine Portuguese students from 8th, 10th, and 12th grade participated in the study. The students were instructed to ask questions on two short science paragraphs that explained natural phenomena. Three task conditions were chosen. Thus, in the “Class” condition, the task was introduced as an activity aimed at developing the capacity to ask questions. In the “Examination” condition, the task was presented as a test on question generation. Finally, in the “Extra‐academic” condition the questioning task was camouflaged as a participation in a research project sponsored by the Ministry of Education and geared at the improvement of science textbooks. The results have shown that students are able to ask many questions when given an opportunity to do so. The study has also proven that students are capable of generating a large volume of causal‐antecedent questions relative to this kind of texts. Finally, no clear effects were found between grade level and/or task demand as defined in the conducted study. © 2000 John Wiley & Sons, Inc. J Res Sci Teach 37: 602–614, 2000  相似文献

The purpose of this research was to examine question asking practices in a youth participatory action research (yPAR) after school program housed at an elementary school. The research question was: In which ways did the adult question asking practices in a yPAR setting challenge and/or reproduce conventional models of power in educational settings? We aligned Fink’s taxonomy (Creating significant learning experiences: an integrated approach to designing college courses. Jossey-Bass, San Francisco, 2003) to Freire’s (The pedagogy of the oppressed. Continuum, New York, 1970/2000) banking concept and problem-posing educational models. All adult questions were categorized from twelve randomly selected yPAR sessions over 2 years. The program served 4th and 5th grade students. Of the 500+ questions adults asked, 17 % were foundational (aligned with Freire’s banking concept). All other questions were aligned with Freire’s problem-posing model. Specifically, 34 % were application, 3 % were integration, 15 % were caring, 11 % were human dimension, and 8 % were learning how to learn questions. By studying question asking patterns and practices, we gained a better understanding of how students and adults navigated this particular after school space, which, at its core, sought to disrupt conventional notions of power and status.  相似文献

The physics questions submitted to an ‘ask a scientist’ website were classified with respect to field of interest in physics, type of requested information in the question (factual, explanatory, etc.), and motivation for asking the question (applicative or non--applicative). In addition, differences in the number of females’ and males’ questions in these classifications were determined. Analysis of 995 physics questions submitted to the website indicated that modern physics questions (30.7%) were the most frequent while vibrations and wave motion questions (3.3%) were the least frequent. More than half of the questions (57.8%) were submitted to request factual information. Motivation to ask a question was inferred from the question, and was generally not related to direct and/or personal application. There were obvious differences in the number of questions asked by females and males: 84.7% of questions were asked by males while 15.3% were asked by females. However, significant gender differences were not observed in field of interest in physics, type of information requested in the question, and motivation for asking the question.  相似文献

Students rarely ask questions related to course content in large-format introductory classes. The use of a Web-based forum devoted to student-generated questions was explored in a second-semester introductory biology course. Approximately 80% of the enrolled students asked at least one question about course content during each of three semesters during which this approach was implemented. About 95% of the students who posted questions reported reading the instructor's response to their questions. Although doing so did not contribute to their grade in the course, approximately 75% of the students reported reading questions posted by other students in the class. Approximately 60% of the students reported that the Web-based question-asking activity contributed to their learning of biology.  相似文献

This study describes the trends in students' explanations of biological change in organisms. A total of 96 student volunteers (8 students from each of 2nd, 5th, 8th, and 12th grades from 3 localities) were interviewed individually and each student was presented a series of graphics depicting natural phenomena. Students' explanations to questions of how something occurred were assigned to one of three categories (responses addressing how something occurred, why something occurred, and 'I don't know'). While the number of responses in each category was roughly equivalent in prominence across grade levels, the majority of students were unable to offer a causal explanation of how a phenomena occurred. An unexpected phenomenon was the students' predilection to redirect the interview question so they could answer them. If asked a how question, as they were in every interview instance, 32% the students answered with a 'why' response. The way biology is taught, the structure of biology or/and how we learn it could shed some light into this phenomenon and has implications for science educators.  相似文献

The purpose of this research was to examine the effects of instruction on students' generation of questions when reading multiple documents. Participants were 151 undergraduate students who were randomly assigned to one of two conditions: a treatment condition that received question generation instruction and a control condition that did not receive question generation instruction. All participants read four primary-source documents and were asked to generate up to 10 questions based on those documents. Results indicate that students generated significantly fewer higher-order integration questions without instructional support. These results are replicated with an alternative document set to demonstrate that the effects found were not due to the specific historical topic.  相似文献

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 laboratory techniques used to try and answer this question on teachers' understanding of laboratory techniques and their ability to formulate research questions. We conducted a laboratory course in microbiology in which the laboratory techniques were presented in an explicit and generalized manner, in the context of specific research questions. During the course, teachers' understanding of laboratory techniques improved as reflected in their answers to exercises given throughout. In addition, teachers' ability to ask research questions, analyzed using Dillon's classification of research questions, also improved. When reflecting upon the course, some teachers attributed the change in their ability to ask research questions to their increased knowledge of techniques, whereas others did not. We conclude that to facilitate research‐question‐asking skills among teachers, they should be provided with knowledge of the relevant laboratory techniques in an explicit fashion. © 2012 Wiley Periodicals, Inc.

The effects of self-regulated strategy development revising instruction for college students that targeted the use of argumentation schemes and critical questions were assessed in three conditions. In the first condition, students were taught to revise their essays by asking and answering critical questions about the argument from consequences and argument from example schemes while writing about controversial topics. In the second condition, students were taught to revise their essays by using argumentation schemes to justify their standpoint, but did not learn the critical questions. In the third condition, students received no instruction about either the argumentation schemes or the critical questions. Compared to students in the contrasting conditions, those who were taught to ask and answer critical questions wrote essays that were of higher quality, and included more counterarguments, alternative standpoints, and rebuttals. These findings indicate that strategy instruction that includes critical standards for argumentation increases college students’ sensitivity to alternative perspectives.  相似文献

This study focuses on the ability of high‐school chemistry students, who learn chemistry through the inquiry approach, to ask meaningful and scientifically sound questions. We investigated (a) the ability of students to ask questions related to their observations and findings in an inquiry‐type experiment (a practical test) and (b) the ability of students to ask questions after critically reading a scientific article. The student population consisted of two groups: an inquiry‐laboratory group (experimental group) and a traditional laboratory‐type group (control group). The three common features investigated were (a) the number of questions that were asked by each of the students, (b) the cognitive level of the questions, and (c) the nature of the questions that were chosen by the students, for the purpose of further investigation. Importantly, it was found that students in the inquiry group who had experience in asking questions in the chemistry laboratory outperformed the control grouping in their ability to ask more and better questions. © 2005 Wiley Periodicals, Inc.

The influence of asynchronous discussion in a virtual learning environment, Blackboard, on subsequent coursework grades was examined with 166 psychology students to determine whether asking questions of the tutor online, and/or reading the questions and the given advice, influenced the grades on the report they were writing. A repeated‐measures quasiexperimental design was used, with and without Blackboard available, to control for confounding variables. The grades on the assignment with Blackboard available were significantly higher than those on the previous assignment (when Blackboard was unavailable). Students who never used Blackboard had significantly lower grades on the assignment than the students who had used it. There was a positive relationship between the number of messages read and the grade achieved on the assignment. Students who read the most discussion board posts wrote significantly better reports (up by 4%) than they had previously. No improvement in grades occurred for the people who read no posts at all. Both the students who asked questions and those who just read the questions and answers (‘lurkers’) ended up with significantly better grades than they had done before Blackboard was introduced.  相似文献

The effects of adult questioning on children’s novel word acquisition during storybook reading were investigated. Three-year-olds were assigned to one of three conditions: vocabulary eliciting questions, noneliciting questions, and no questions (control). General vocabulary comprehension and novel word knowledge were equivalent across the groups before the storybook reading intervention. Children were read 3 storybooks repeatedly across 4 reading sessions and were tested for production and comprehension of novel words in the final session. Children’s novel word comprehension increased more in both question conditions than in the control condition, suggesting that type of question is not as important to word learning as children’s active engagement in discussion about novel words in general. Novel word production was not strongly affected by any of the reading conditions. However, asking children noneliciting questions did appear to foster production of new words more than not asking questions at all.  相似文献

This study demonstrates a method for obtaining data on developmental changes in adolescents' interest in human sexuality. A content analysis was done on a sample of 874 student-generated questions. Question boxes were placed in classrooms so students could anonymously submit questions. In deference to perceived community pressure, questions on abortion, homosexuality, and masturbation were not allowed. Students who wrote the questions are 7th, 8th, and 10th graders enrolled in 13 different public schools. The schools are located in several small communities and on an American Indian reservation in a rural area of northern California. All children who participated did so voluntarily and with parental permission. Of the total 874 questions. 7th and 8th graders provided 593, while sophomores accounted for 233. Gender information was available only for 7th and 8th graders. Boys asked 173 questions while girls asked 241. The data are broken down by gender and by grade (7th and 8th vs. 10th). Findings reveal that younger students show more interest in the meaning of slang terms, their reproductive physiology, and intercourse. Older students show greater interest in contraception and health risks. Males are interested in slang and intercourse while females are more concerned with health risks and communication. One unexpected finding indicates that among younger children, boys and girls are equally interested in birth control and pregnancy; in the lower grades then, may be the prime time to use sex education programs to strengthen the sense of dual responsibility for knowledge about contraception and pregnancy. Also, the relative absence of questions on disallowed issues (2.5%) makes it apparent that sex educators can effectively suppress inquiry into topics that are of great interest to youngsters; only about 1/3 of the students indicated that their parents had discussed these disllowed issues, yet 48% of the students expressed interest in knowing more about abortion.  相似文献

Inferences and recall at ages 4 and 7 were studied as a function of the cause of a target event, the presence and timing of questions prior to recall, and the type of inference demanded by the questions. 7-year-olds inferred and recalled well with stories containing any of the causal connections employed in the study. 4-year-olds performed better when physical causes, rather than either psychological causes or enabling relations, connected events. Timing of questions did not affect the 7-year-olds' inferences, but asking questions interfered with their recall. Questions about story events aided the 4-year-olds' ability to make inferences and to recall, especially when causal connections were least specified and when questions were asked following the story. 4- and 7-year-olds also differed in responding to demands for 3 specific types of inference. 4-year-olds produced significantly more unconstrained inferences than logical or constrained informational inferences. 7-year-olds were most responsive to logical inference questions, and produced significantly more logical than constrained inferences.  相似文献

The aim of this study is to analyse the effect of tasks on the detection of explanation obstacles when secondary school students read scientific texts. Students were instructed to read short passages under different task conditions, and to ask questions if necessary. Obstacle detection was operationalised in terms of the type of questions asked by the students. The experiment examined the influence of goals associated with the task of reading to understand a text vs. reading to perform a procedure described by the text (a science experiment). Significantly, more explanation obstacles were found in the understanding condition than in the experiment condition. Scientific text also had an effect on the explanation obstacles detected.  相似文献

Flexibility in problem solving has been widely recognized as an important skill for students' mastery of mathematics. Here we utilize the Opportunity-Propensity framework to investigate student characteristics, teacher characteristics, and teacher instructional practices that may be associated with students' gains in flexibility in algebra. Teacher and student data were collected from 8th and 9th grade Algebra I teachers in Massachusetts as part of a larger study on the impact of a researcher-developed year-long supplementary curriculum that focused on improving students' flexibility. We explore student demographics, teacher background characteristics and teacher instructional practices as predictors of student gains in flexibility. We further investigate instructional practices associated with flexibility gains through an analysis of teacher questioning in the classroom for teachers whose students achieved the greatest gains in flexibility and those whose students achieved the least gains. Our results indicate that prior knowledge is a reliable predictor of flexibility gains and that gender is an important student background characteristic associated with the development of flexibility. In addition, although high and low gain teachers did not differ in their implementation fidelity, high flexibility gain teachers asked more open-ended questions that prompted students to verbalize the main ideas of the lesson.  相似文献
