Relationships among informal learning environments,teaching procedures and scientific reasoning ability

Informal learning experiences have risen to the forefront of science education as being beneficial to students' learning. However, it is not clear in what ways such experiences may be beneficial to students; nor how informal learning experiences may interface with classroom science instruction. This study aims to acquire a better understanding of these issues by investigating one aspect of science learning, scientific reasoning ability, with respect to the students' informal learning experiences and classroom science instruction. Specifically, the purpose of this study was to investigate possible differences in students' scientific reasoning abilities relative to their informal learning environments (impoverished, enriched), classroom teaching experiences (non-inquiry, inquiry) and the interaction of these variables. The results of two-way ANOVAs indicated that informal learning environments and classroom science teaching procedures showed significant main effects on students' scientific reasoning abilities. Students with enriched informal learning environments had significantly higher scientific reasoning abilities compared to those with impoverished informal learning environments. Likewise, students in inquirybased science classrooms showed higher scientific reasoning abilities compared to those in non-inquiry science classrooms. There were no significant interaction effects. These results indicate the need for increased emphases on both informal learning opportunities and inquiry-based instruction in science.     

Creating Spaces for Collaboration in Community Co‐design

Urgent societal challenges have led to unease in our socio‐cultural interactions and the production systems that underpin our lives. To confront such challenges, collaboration stands out as an essential approach in accomplishing joint goals and producing new knowledge. It calls for interdisciplinary methodologies such as co‐design, an approach capable of bridging multiple expertise. The core activities of co‐design are based on the premise of collaboration and on developing creative social environments. Yet achieving collaboration through co‐design is challenging as people need to understand each other, and develop trust and rapport. We argue that ‘informal‐mutual learning’ is central to building mutual understanding. This article explores how we create spaces for collaboration through co‐design by examining the social environments supporting them. It examines the value of collaboration and its impact upon participants within an action research project conducted in Scotland. We identified Cultural‐Historical Activity Theory (CHAT) as a suitable theoretical framework. It offers support for holistic inquiry into participation and learning. Its strength was in the attention that it pays to multi‐dimensional human interactions within the social environment. This led to an understanding of the concepts of boundary‐crossing and boundary space examined through a CHAT lens. The findings shed light on four designerly conditions supporting informal‐mutual learning when engaged in collaboration during co‐design situations: choreography and orchestration, aesthetics, playfulness, and quality and quantity of participation. The findings enable us to elaborate on the theorisation of boundary space, a theoretical space for the assemblage of multiple levels of expertise to achieve collaboration.     

Scientific knowledge and attitude change: The impact of a citizen science project

This paper discusses the evaluation of an informal science education project, The Birdhouse Network (TBN) of the Cornell Laboratory of Ornithology. The Elaboration Likelihood Model and the theory of Experiential Education were used as frameworks to analyse the impact of TBN on participants’ attitudes toward science and the environment, on their knowledge of bird biology, and on their understanding of the scientific process. The project had an impact on participants’ knowledge of bird biology. No statistically significant change in participants’ attitudes toward science or the environment, or in participants’ understanding of the scientific process, could be detected. The results suggest that projects must make explicit to participants the issues that they are experiencing. In addition, the results suggest that more sensitive measures need to be designed to assess attitude change among environmentally aware citizens.     

“There’s got to be a better way to do this”: a qualitative investigation of informal learning among instructional designers

This study employed a qualitative research design to investigate informal learning among practicing instructional designers. Prior research has examined how instructional designers spend their time, make decisions, use theory, solve problems, and so on, but no published research has explored the nature and role of informal learning in instructional design work. Based on intensive interviews of practitioners in the field, this study produced eight themes organized according to two metathemes: (a) the nature of informal learning in instructional design practice and (b) instructional design as informal learning. Specific themes concerned what instructional designers learn through informal practical experience, how they learn it, and the meaning of this kind of learning for various aspects of their work. Overall, these results suggest that informal learning is a vital part of instructional design practice and that design itself can be thought of as a specialized type of informal learning. Other conclusions regarding informal learning in design are discussed and future directions for research are offered.     

Understanding How Families Use Magnifiers During Nature Center Walks

This analysis uses a sociocultural learning theory and parent–child interaction framework to understand families’ interactions with one type of scientific tool, the magnifier, during nature walks offered by a nature center. Families were video recorded to observe how they organized their activities where they used magnifiers to explore in the outdoors. Findings include that families used magnifiers for scientific inquiry as well as for playful exploration. Using the concept of guided facilitation where families develop roles to support their joint endeavor, three roles to support family thinking were found to be: (a) tool suggester, (b) teacher, and (c) exploration ender. Some families struggled to use magnifiers and often, parents and older siblings provided support for younger children in using magnifying lenses. Implications to informal science learning theory are drawn and suggestions for future family learning research are offered: (a) inclusion of sociocultural and situated perspectives as theories to study informal learning in outdoor spaces, (b) further study on the role of siblings in family interactions, (c) design-based research is needed to encourage family role-taking when engaging in science practices, and (d) new conceptualizations on how to design informal programs that support science learning while leaving space for visitors’ personal agendas and interests that can guide the families’ activities.     

The impact of a classroom intervention on grade 10 students' argumentation skills,informal reasoning,and conceptual understanding of science

The literature provides confounding information with regard to questions about whether students in high school can engage in meaningful argumentation about socio‐scientific issues and whether this process improves their conceptual understanding of science. The purpose of this research was to explore the impact of classroom‐based argumentation on high school students' argumentation skills, informal reasoning, and conceptual understanding of genetics. The research was conducted as a case study in one school with an embedded quasi‐experimental design with two Grade 10 classes (n = 46) forming the argumentation group and two Grade 10 classes (n = 46) forming the comparison group. The teacher of the argumentation group participated in professional learning and explicitly taught argumentation skills to the students in his classes during one, 50‐minute lesson and involved them in whole‐class argumentation about socio‐scientific issues in a further two lessons. Data were generated through a detailed, written pre‐ and post‐instruction student survey. The findings showed that the argumentation group, but not the comparison group, improved significantly in the complexity and quality of their arguments and gave more explanations showing rational informal reasoning. Both groups improved significantly in their genetics understanding, but the improvement of the argumentation group was significantly better than the comparison group. The importance of the findings are that after only a short intervention of three lessons, improvements in the structure and complexity of students' arguments, the degree of rational informal reasoning, and students' conceptual understanding of science can occur. © 2010 Wiley Periodicals, Inc.

Creating an information-rich learning environment to enhance design student learning: challenges and approaches

The use of technology with engineering design students is well established, with shared workspaces being particularly supportive of the collaborative design process. This paper reports on a study where a design knowledge framework involving three learning loops was used to analyse the effectiveness of shared workspaces and digital repositories in supporting design education. The issues discussed include the relationship between knowledge and information structures, the importance of integrating information literacy support, and the need for different systems within the learning environment to support formal and informal storage of resources. These issues are explored within the context of experiences of working in a multidisciplinary team with different approaches, research methodologies, and discourses.

High School Students’ Informal Reasoning Regarding a Socio‐scientific Issue,with Relation to Scientific Epistemological Beliefs and Cognitive Structures

This study investigated the relationship among 68 high school students’ scientific epistemological beliefs (SEBs), cognitive structures regarding nuclear power usage, and their informal reasoning regarding this issue. Moreover, the ability of students’ SEBs as well as their cognitive structures for predicting their informal reasoning regarding this issue was also examined. The participants’ SEBs were assessed with a quantitative instrument; their cognitive structures were assessed through tape‐recorded interviews and were further analyzed with the ‘flow map method’; their reasoning regarding nuclear power usage was assessed with an open‐ended questionnaire; and, then, their responses were analyzed both qualitatively and quantitatively. It was revealed that students’ beliefs about the justification of scientific knowledge (an aspect of the beliefs on the nature of knowing science) were significantly correlated with their reasoning quality; the extent and the richness of students’ cognitive structures as well as their usage of the information processing mode, ‘comparing,’ were positively correlated with their reasoning quality. A series of regression analyses further confirmed that students’ use of the information processing mode, ‘comparing,’ was the most significant factor for predicting reasoning quality, while their beliefs regarding the justification of scientific knowledge was the other important predictor.     

移动设备在非正式科学学习中的应用——基于近十年来国外相关实证研究的综述

文章基于内容分析的视角,梳理了近十年来国外有关在非正式科学学习环境中应用移动设备(如智能手机、平板电脑)的实证研究,发现:移动设备在非正式科学学习中的应用尚不广泛,且呈现地区研究差异;研究者多关注小学阶段生命科学的学习,并与户外环境研学旅行联系紧密;移动设备在非正式科学学习中不仅扮演“学习助手”的角色,而且可作为学习资源直观呈现学习内容。此外,文章针对未来研究非正式科学学习提出了建议,如重视基础教育阶段非正式科学学习的机会、设计良好移动学习资源或选择合适移动技术、思考移动设备应用于非正式科学学习的结果测量方式、加强对多个科学领域进行非正式科学学习的探索,以期为相关研究提供参考。     

Making sense of young people’s digital practices in informal contexts: The Digital Practice Framework

There is a growing body of research looking at young people’s use of digital technology in informal contexts. However, there is a gap in the literature about how to describe and categorise young people’s digital practices in such contexts. This gap is important because in order to be able to understand the differences between young people’s digital practices in informal contexts and how these differences arise, you first need to be able to describe and categorise those differences in meaningful ways. You need to be able to answer the question “How do young people use digital technology in informal contexts?” in order to be able to answer questions such as “How do children’s digital practices in informal contexts vary?” and “Why do children’s digital practices vary?”. This paper is significant because it introduces The Digital Practice Framework, an original, theoretically informed, tool to fill this critical gap in the literature. It goes on to indicate how this framework has been used to analyse the factors that facilitate or hinder the development of young people’s digital practices in informal contexts.

Conceptual continuity and the science of baseball: using informal science literacy to promote students’ science learning

This project explores conceptual continuity as a framework for understanding students’ native ways of understanding and describing. Conceptual continuity suggests that the relationship between the use of words in one genre and the scientific genre can exist at varying levels of association. This perspective can reveal the varied relationships between ideas explained in everyday or vernacular genres and their association to scientific explanations. We conducted a 2-year study involving 15 high school baseball players’ understanding of the physics involved in baseball. First, we conducted a quantitative assessment of their science understanding by administering a test prior to season one (2006) and season two (2007). Second, we examined the types of linguistic resources students used to explain their understanding. Third, we revisited our data by using conceptual continuity to identify similarities between students’ conceptual understanding in the informal contexts and their similarities to canonical scientific ideas. The results indicated students’ performance on the multiple-choice questions suggested no significant improvement. The qualitative analyses revealed that students were able to accurately explain different components of the idea by using a diversity of scientific and non-scientific genres. These results call attention to the need to reconstruct our vision of science learning to include a more language sensitive approach to teaching and learning.     

Lakatos’ Scientific Research Programmes as a Framework for Analysing Informal Argumentation about Socio‐scientific Issues

The purpose of this study is to explore how Lakatos’ scientific research programmes might serve as a theoretical framework for representing and evaluating informal argumentation about socio‐scientific issues. Seventy undergraduate science and non‐science majors were asked to make written arguments about four socio‐scientific issues. Our analysis showed that the science majors’ informal arguments were significantly better than the non‐science majors’ arguments. In terms of the resources for supporting reasons, we find that personal experience and scientific belief are the two categories that are generated most often in both groups of the participants. Besides, science majors made significantly greater use of analogies, while non‐science majors made significantly greater use of authority. In addition, both science majors and non‐science majors had a harder time changing their arguments after participating in a group discussion. In the study of argumentation in science, scholars have often used Toulmin’s framework of data, warrant, backing, qualifiers, claims, and rebuttal. Our work demonstrates that Lakatos’ work is also a viable perspective, especially when warrant and backing are difficult to discern, and when students’ arguments are resistant to change. Our use of Lakatos’ framework highlights how the ‘hard core’ of students’ arguments about socio‐scientific issues does, indeed, seem to be protected by a ‘protective belt’ and, thus, is difficult to alter. From these insights, we make specific implications for further research and teaching.     

A comparative study of digital informal learning: The effects of digital competence and technology expectancy

The objective of this paper is to investigate the effects of digital competence and technology expectancy and how they interact with cultural differences on digital informal learning (DIL) of university students have different cultural backgrounds. Empirical data collected from a survey conducted both in China and Belgium, the total sample consists of 335 Chinese and 197 Belgians. Partial least square with formative assessment was employed to test the proposed model and multi-groups comparison analysis was conducted to examine the moderation effects of cultural difference on influential factors related to students’ DIL behaviors. The results highlighted the essential role of digital competence and technology expectancy in DIL. Cultural difference revealed a strong influence on the motive pattern of DIL behaviors. This study raised some major implications for educational researchers and practitioners alike. Specifically, the paper introduced and stressed the role of digital competence in informal learning context which was rarely considered in prior studies in terms of learning ecology. The study expanded current theoretical understanding of technology adoption in informal learning environments across different cultural contexts. The finding has shown both a homogeneous informal learning behavior and motive variance between different two cultural backgrounds. The study also provided a set of practical implications, including the need for digital competence training in today’s digital era, and the need for a satisfactory user interface design globally.     

Randomization‐based statistical inference: A resampling and simulation infrastructure

Statistical inference involves drawing scientifically‐based conclusions describing natural processes or observable phenomena from datasets with intrinsic random variation. We designed, implemented, and validated a new portable randomization‐based statistical inference infrastructure ( http://socr.umich.edu/HTML5/Resampling_Webapp ) that blends research‐driven data analytics and interactive learning, and provides a backend computational library for managing large amounts of simulated or user‐provided data. We designed, implemented and validated a new portable randomization‐based statistical inference infrastructure ( http://socr.umich.edu/HTML5/Resampling_Webapp ) that blends research‐driven data analytics and interactive learning, and provides a backend computational library for managing large amounts of simulated or user‐provided data. The core of this framework is a modern randomization webapp, which may be invoked on any device supporting a JavaScript‐enabled web browser. We demonstrate the use of these resources to analyse proportion, mean and other statistics using simulated (virtual experiments) and observed (e.g. Acute Myocardial Infarction, Job Rankings) data. Finally, we draw parallels between parametric inference methods and their distribution‐free alternatives. The Randomization and Resampling webapp can be used for data analytics, as well as for formal, in‐class and informal, out‐of‐the‐classroom learning and teaching of different scientific concepts. Such concepts include sampling, random variation, computational statistical inference and data‐driven analytics. The entire scientific community may utilize, test, expand, modify or embed these resources (data, source‐code, learning activity, webapp) without any restrictions.     

Robotics competitions and science classrooms

This paper looks at the distinctions between science classrooms and the robotics competition described in the article “Examining the mediation of power in a collaborative community: engaging in informal science as authentic practice” written by Anton Puvirajah, Geeta Verma and Horace Webb. Using the framework of “productive disciplinary engagement” and discussing each principle in turn, the article argues that in order to bring the advantages of informal learning environments into regular classrooms we especially need to address student interest through task design and to change curricular requirements to agree with changing educational values.
