Student interest generated during an inquiry skills lesson

JOURNAL OF RESEARCH IN SCIENCE TEACHING, Issue 2 2009
David H. Palmer
Abstract "Situational interest" is a short-term form of motivation which occurs when a specific situation stimulates the focused attention of students (e.g., a spectacular science demonstration could arouse transient interest amongst nearly all the students in a class, even those who are not normally interested in science). However, there have been very few studies of situational interest and its potential to motivate students in science classrooms. The purpose of this project was to investigate situational interest and its sources. Small groups of grade 9 students participated in a science lesson which focused on inquiry skills, and data were obtained on their interest levels and sources of interest. The results indicated that interest arousal was substantial but did fluctuate throughout the lesson, according to the types of activities in which students were involved. The main source of interest was novelty, although choice, physical activity, and social involvement were also implicated. © 2008 Wiley Periodicals, Inc. J Res Sci Teach 46: 147,165, 2009 [source]


Individual and group meaning-making in an urban third grade classroom: Red fog, cold cans, and seeping vapor

JOURNAL OF RESEARCH IN SCIENCE TEACHING, Issue 9 2005
Sherry Southerland
We examined third graders' understandings of condensation using an expanded notion of the Emergent Perspective, a reflexive consideration of individual and group meaning-making situated in the culture of the classroom. Data were collected from two small groups of students in an inquiry-based, urban classroom during a unit on the water cycle. Measures included conceptual pre-/posttests, interviews, written work, and discourse analyses of a science lesson. Although we identified the supportive role of the teacher's explicit assessments of children's ideas, within the small groups, the force that most potently shaped meaning-making was students' persuasive power, which was in part influenced by the rhetorical moves employed. Specifically, students' evaluative comments (a type of rhetorical move) about contributions of other group members seemed to be particularly persuasive in these groups. Evaluative comments, apart from students' academic status, were shown to be an important influence in not only social knowledge production but also in individual internalization. Our explanation focuses on the particular discursive practices as intellectual resources of urban students, but we are also mindful of the cognitive complexity of the material and the developmental abilities of the students. © 2005 Wiley Periodicals, Inc.

National Science Foundation Graduate Teaching Fellows Promote Food Science Education in K-12 Schools in Maine

JOURNAL OF FOOD SCIENCE EDUCATION, Issue 4 2003
B. Calder
ABSTRACT: The Univ. of Maine is participating in the National Science Foundation's (NSF) GK-12 Teaching Fellows program. Between 2000 and 2003, 4 food science graduate students demonstrated food- and nutrition-related science lessons, among other innovative activities. This article includes details of an activity on natural dyes to help students understand plant pigments. Assessment of the NSF GK-12 program is ongoing both locally and nationally. NSF's goals are being met, including one of the most important, which is the effect of NSF Fellows as role models on K-12 students. [source]


Learning from and responding to students' questions: The authoritative and dialogic tension

JOURNAL OF RESEARCH IN SCIENCE TEACHING, Issue 2 2010
Orlando G. Aguiar
Abstract In this study we present an analysis of classroom interactions initiated by students' wonderment questions. Our interest in such events arises from their potential to stimulate active intellectual engagement in classrooms, which can impact upon the subsequent development of the classroom discourse. In investigating this issue we shall address the following research question: How do student questions impact upon the teaching explanatory structure and modify the form of the ongoing classroom discourse, in selected science lessons? From data collected in a Brazilian secondary school we have selected three classroom episodes, with large differences in both the context in which the student's question emerges and in the communicative approach developed in response to it. The analysis, based on the framework proposed by Mortimer and Scott [Mortimer and Scott (2003). Meaning making in secondary science classrooms. Maidenhead: Open University Press], shows that questions made by students are important in providing feedback from students to the teacher, enabling adjustments to the teaching explanatory structure. These adjustments sometimes occur smoothly, at other times with major changes to the features of the classroom discourse, and elsewhere with misunderstanding and disagreement. The data also suggest the need to consider students' intentions and their active participation in the negotiation of both the content and structure of classroom discourse. © 2009 Wiley Periodicals, Inc.

Teaching nature of science explicitly in a first-grade internship setting

JOURNAL OF RESEARCH IN SCIENCE TEACHING, Issue 4 2006
Valarie L. Akerson
This case study focused on a preservice teachers' (Morgan) efforts to explicitly emphasize nature of science (NOS) elements in her first-grade internship classroom. The study assessed the change in first grade students' views of the inferential, tentative, and creative NOS as a result of the explicit instruction. Morgan held appropriate views of NOS, had the intention and motivation to teach NOS, and had a supporting experience explicitly emphasizing NOS embedded in physics content to peer college students. Data sources included weekly classroom observations of explicit NOS science lessons taught by Morgan, interview of Morgan to determine that her views of NOS were informed and that she would have the NOS content knowledge to teach in line with recommended reforms, and interviews of the first-grade students pre- and postinstruction to determine the influence of Morgan's instruction on their views of observation and inference, the tentative NOS, and the creative and imaginative NOS. Data were analyzed to determine (a) the approaches Morgan used to emphasize NOS in her instruction, and (b) students' views of NOS pre- and postinstruction to track change in their views. It was found that Morgan was able to explicitly emphasize NOS using three teacher-designed methods, and that the influence on student views of the inferential, tentative, and creative NOS was positive. Implications for teacher development are provided. © 2006 Wiley Periodicals, Inc. J Res Sci Teach 43: 377,394, 2006 [source]


Inquiry in interaction: How local adaptations of curricula shape classroom communities

JOURNAL OF RESEARCH IN SCIENCE TEACHING, Issue 9 2004
Noel Enyedy
In this study, we seek a better understanding of how individuals and their daily interactions shape and reshape social structures that constitute a classroom community. Moreover, we provide insight into how discourse and classroom interactions shape the nature of a learning community, as well as which aspects of the classroom culture may be consequential for learning. The participants in this study include two teachers who are implementing a new environmental science program, Global Learning through Observation to Benefit the Environment (GLOBE), and interacting with 54 children in an urban middle school. Both qualitative and quantitative data are analyzed and presented. To gain a better understanding of the inquiry teaching within classroom communities, we compare and contrast the discourse and interactions of the two teachers during three parallel environmental science lessons. The focus of our analysis includes (1) how the community identifies the object or goal of its activity; and (2) how the rights, rules, and roles for members are established and inhabited in interaction. Quantitative analyses of student pre- and posttests suggest greater learning for students in one classroom over the other, providing support for the influence of the classroom community and interactional choices of the teacher on student learning. Implications of the findings from this study are discussed in the context of curricular design, professional development, and educational reform. ? 2004 Wiley Periodicals, Inc.

Investigating the efficacy of concept mapping with pupils with autistic spectrum disorder

BRITISH JOURNAL OF SPECIAL EDUCATION, Issue 3 2007
Veronica Roberts
Pupils with autism often present significant challenges to teachers. They seem to have real strengths in visual processing but a cognitive style that encourages them to focus on detail rather than the overarching connections between concepts. Veronica Roberts, currently undertaking doctoral training at the Institute of Education, University of London, in order to become an educational psychologist, and Richard Joiner, senior lecturer in the Department of Psychology at the University of Bath, set out to explore these issues. In this article, they report the outcomes of a naturalistic experiment in which they investigated the utility of concept mapping as an educational strategy with pupils diagnosed with an autistic spectrum disorder (ASD). Theoretical arguments supporting the use of concept mapping with an autistic population are outlined in the paper. A tutor group of ten pupils with ASD, aged between 11 and 14 years, took part in the study. Concept mapping tasks were integrated within National Curriculum science lessons in collaboration with the school's science teacher. The study found that the increase in pupil performance in subject-specific questionnaires was nearly four times greater in the concept mapping condition than after a more conventional teaching intervention. Veronica Roberts and Richard Joiner tentatively draw out the implications of their work for staff who work with pupils with ASD and make recommendations for further research into the use of these learning strategies.
