Supporting family conversations and children's STEM learning in a children's museum

This study tested the effectiveness of a facilitated educational program in a museum for promoting family conversations and children's learning about STEM. A sample of 130 families (71 European-American; 33 African-American; and 26 Hispanic-American) with children M age = 6.42 years were observed in a building construction exhibit. Prior to building, families were randomly assigned to conditions that varied in terms of the instructions about a key engineering principle and elaborative question-asking they received. Conversation instruction resulted in adults’ asking double the number of Wh-questions compared to families who did not receive the instruction. The building instruction was important in promoting increases in adults’ STEM-related talk during the building activity, as well as in the children's STEM talk when prompted for information about what they had learned. The effects of the instructions did not vary by families’ ethnic background. Implications for facilitating family conversations and children's learning related to STEM are discussed.     

More than science: family learning in a Mexican science museum

Latin American audiences living in their countries of origin are poorly understood as museum learners due to the scarcity of research in this field. Through a case study approach, I investigate and report on the ways of learning of 20 Mexican family groups. In particular, I examine the influence of the Mexican sociocultural context on the participant family members’ learning outcomes from a Mexican science museum. Conducted in Universum Museo de las Ciencias, a science museum located in Mexico City, this research study is based on the premise that understanding the role of the sociocultural elements of learning is essential to understanding the nature of learning in museums. The cognitive and social outcomes of the participants are discussed in the light of the sociocultural elements that define Mexicans as museum learners.     

Reconceptualising inquiry in science education

Decades of discussion and debate about how science is most effectively taught and learned have resulted in a number of similar but competing inquiry models. These aim to develop students learning of science through approaches which reflect the authenticity of science as practiced by professional scientists while being practical and manageable within the school context. This paper offers a collection of our current reflections and suggestions concerning inquiry and its place in science education. We suggest that many of the current models of inquiry are too limited in their vision concerning themselves, almost exclusively, with producing a scaffold which reduces the complex process of inquiry into an algorithmic approach based around a sequence of relatively simple steps. We argue that this restricts students’ experience of authentic inquiry to make classroom management and assessment procedures easier. We then speculate that a more integrated approach is required through an alternative inquiry model that depends on three dimensions (conceptual, procedural and personal) and we propose that it will be more likely to promote effective learning and a willingness to engage in inquiry across all facets of a students’ school career and beyond.     

Sex differences in science museum exhibit attraction

This study examines the relative attraction of hands-on, interactive science museum exhibits for females and males. Studies have demonstrated that such exhibits can be effective learning experiences for children, with both academic and affective benefits. Other studies have shown that girls and boys do not always experience the same science-related educational opportunities and that, even when they do, they do not necessarily receive the same benefits from them. These early differences can lead to more serious educational and professional disparities later in life. As interactive museum exhibits represent a science experience that is-readily available to both girls and boys, the question arose as to whether they were being used similarly by the two groups as well as by adult women and men. It was found that both girls and boys used all types of exhibits, but that girls were more likely than boys to use puzzles and exhibits focusing on the human body; boys were more likely than girls to use computers and exhibits illustrating physical science principles. However, this was less true of children accompanied by adults (parents) than it was of unaccompanied children on school field trips who roamed the museum more freely.     

Dialogic processes that enable student teachers' learning about pupil learning in mentoring conversations in a Lesson Study field practice

This study investigates dialogic processes in student teachers' mentoring conversations in field practice, where Lesson Study (LS) was used as a context for establishing a dialogic learning community in one student group in science. We apply an analytical framework associated with Sociocultural Discourse Analysis to identify utterances that have the potential to create a dialogic space and contribute to ‘interthinking’ among the participants. The findings show the important role of the mentor teacher as a facilitator and a ‘knowledgeable other’, challenging the student teachers to reflect on chosen activities using predictions and detailed observations related to pupils' learning.     

科学教学中的"探究"释义

根据教学论,科学教学中的“探究”可有三层含义:作为教学目标,指学生应掌握的科学探究技能,要理解的科学探究特性;作为教学原则,指激发学生积极探究未知、主动建构意义的基本教学要求;作为教学方法,指学生在教师指导下所采用的类似科学探究过程的学习方式或程序。     

Community and inquiry: journey of a science teacher

In this case study, we examine a teacher’s journey, including reflections on teaching science, everyday classroom interaction, and their intertwined relationship. The teacher’s reflections include an awareness of being “a White middle-class born and raised teacher teaching other peoples’ children.” This awareness was enacted in the science classroom and emerges through approaches to inquiry. Our interest in Ms. Cook’s journey grew out of discussions, including both informal and semi-structured interviews, in two research projects over a three-year period. Our interest was further piqued as we analyzed videotaped classroom interaction during science lessons and discovered connections between Ms. Cook’s reflections and classroom interaction. In this article, we illustrate ways that her journey emerges as a conscientization. This, at least in part, shapes classroom interaction, which then again shapes her conscientization in a recursive, dynamic relationship. We examine her reflections on her “hegemonic (cultural and socio–economic) practices” and consider how these reflections help her reconsider such practices through analysis of classroom interaction. Analyses lead us to considering the importance of inquiry within this classroom community.

The impact of a class visit to a participatory science museum exhibit and a classroom science lesson

Cognitive and affective outcomes of a class visit to a participatory science museum were examined by comparing responses of 416 fifth and sixth graders randomly assigned to four conditions (control, exhibit only, lesson only, and exhibit followed by lesson) and two tests (verbal and visual). Students visiting a simple machines exhibit scored higher on a test of science content than the control group, but lower than the group attending a classroom lesson in the museum. The study did not demonstrate conclusively a cognitive advantage of having the exhibit experience prior to the lesson. Scores on the visual test were consistently higher than scores on the verbal test. Study findings indicate that the particular strength of the science museum exhibit lies in the affective domain. Students found the exhibit much more enjoyable, interesting, and motivational than a classroom lesson. Implications of the findings for science education are discussed.     

Science identity trajectories throughout school visits to a science museum

Research has repeatedly demonstrated how informal learning environments afford science-identity development by fostering a broader array of interactions and recognizing more varied participation modes and roles, as compared to the classroom. Thus, science teachers are encouraged to take students to field trips in informal environments, including science museums. However, the question of whether and how informal environments indeed support science identities also in a schooling context (i.e., in field trips) has not yet been explored. This case study addresses this question by analyzing identity trajectories of three students throughout six school visits to an Israeli science museum. We observed and recorded these students in the museum over the course of 3 years (fourth to sixth grade). We also visited their school and interviewed them after each visit. Drawing on a sociocultural interactional approach to identity, we analyzed 18 hr of video and audio recordings, tracking the participation of the three students across time and contexts, comparing between the students, points in time and settings, including structured (museum lab), semi-structured (riddle-solving activities in exhibition halls), and unstructured settings (free exploration). We employed linguistic ethnographic methods and microanalysis to examine the ways in which the students participated and their positioning by self and others. While we found differences between settings within the museum, overall, the findings show that the museum reproduced the school's interaction, positioning, and roles. The “(non)science person” in school was also the “(non)science person” in the museum, and thus, the museum visits did not appear to shift identity trajectories. These findings challenge the premise that informal environments support the development of science identities also in a schooling context and call for a more critical view of such fieldtrips in terms of their pedagogical and physical design, facilitation approach, and consideration of peers' social interaction.     

An examination of the interactions between museum educators and students on a school visit to science museum

Today, science is a major part of western culture. Discussions about the need for members of the public to access and understand scientific information are therefore well established, citing the importance of such information to responsible citizenship, democracy, socially accountable scientific research and public funding (National Research Council [2009] Learning science in informal environments: People, places, and pursuits. National Academies Press). In recent years there has been an increased interest in investigating not just what visitors to informal environments have learnt after a visit, but also how visitors interact and engage with exhibits during the visit (Davidsson & Jakobsson [2012] Understanding interactions at science centers and museums: Approaching sociocultural perspectives. Rotterdam: Sense Publishers). Within the field of school visits to science museums, however, interactions between students and museum educators (MEs) remain relatively unexplored. In our study of such school visits, we are mainly interested in the interactions that take place between three agents—the students, the museum educator and the physical setting of the exhibit. Using moment-to-moment fine grain analysis of multiple interactions allowed us to identify recurring patterns between students and the museum educators around exhibits, and to examine the MEs’ mediational role during the interactions, and the practices they employ to engage students with exhibits. Our study revealed that most interactions between MEs and students consist of technical explanations of how to operate the exhibits. The interactions that do move past this stage often include two main practices, which the MEs use to promote students’ engagement with the exhibits: physical instruction and engaging the students emotionally. Understanding what is actually happening in the learning process that occurs during students’ interactions with exhibits can help museum educators and exhibit designers improve the experiences of students on school visits.     

Student leadership in small group science inquiry

Background: Science educators have sought to structure collaborative inquiry learning through the assignment of static group roles. This structural approach to student grouping oversimplifies the complexities of peer collaboration and overlooks the highly dynamic nature of group activity.

Purpose: This study addresses this issue of oversimplification of group dynamics by examining the social leadership structures that emerge in small student groups during science inquiry.

Sample: Two small student groups investigating the burning of a candle under a jar participated in this study.

Design and method: We used a mixed-method research approach that combined computational discourse analysis (computational quantification of social aspects of small group discussions) with microethnography (qualitative, in-depth examination of group discussions).

Results: While in one group social leadership was decentralized (i.e., students shared control over topics and tasks), the second group was dominated by a male student (centralized social leadership). Further, decentralized social leadership was found to be paralleled by higher levels of student cognitive engagement.

Conclusions: It is argued that computational discourse analysis can provide science educators with a powerful means of developing pedagogical models of collaborative science learning that take into account the emergent nature of group structures and highly fluid nature of student collaboration.

Collaboration modality, cognitive load, and science inquiry learning in virtual inquiry environments

Educational multi-user virtual environments (MUVEs) have been shown to be effective platforms for situated science inquiry curricula. While researchers find MUVEs to be supportive of collaborative scientific inquiry processes, the complex mix of multi-modal messages present in MUVEs can lead to cognitive overload, with learners unable to effectively process the rich information encountered in virtual space. In this study, we investigated the effect of communication modality on cognitive load and science inquiry learning in students completing a science inquiry curriculum in an educational MUVE. Seventy-eight undergraduate education majors from a large southwestern university participated in this control-treatment study. Significant positive results were found for reducing cognitive load for participants communicating through voice-based chat, although this reduction was not found to influence learning outcomes. We conclude that use of voice-based communication can successfully reduce cognitive load in MUVE-based inquiry curricula.     

Concept maps as assessment in science inquiry learning - a report of methodology

Increasing availability of technologies, such as CD ROMs and the World Wide Web, in schools means that more teachers will have the potential to implement student-centred, inquiry-based approaches to learning. Assessing what each student knows in a broad subject area, such as science, is difficult. Assessing students' understanding in circumstances where each student may pursue different topics of study, where there is no way to predict in advance what those topics of study will be and where the possible topics of study include natural phenomena which are only beginning to be studied by professional scientists, is even more difficult. The authors recently faced such a challenge. To meet the challenge, the authors chose to assess student learning using an open-ended concept map activity combined with a rubric which extracts quantitative information about the quality of understanding from each map. This article describes the method the authors developed, including tests of reliability and validity.
