Science in the making: 1930s citizen science on the BBC

ABSTRACT

During 1931–1933 several BBC radio broadcasts invited listeners to participate in what would now be termed ‘citizen science’ experiments. Scientists broadcast on a research topic, and asked for relevant data and observations from listeners. Most of these broadcasts were part of the Science in the Making series. Topics investigated ranged across natural history, meteorology, auditory perception, dreams and social science. One Science in the Making broadcast resulted in an article in a refereed academic journal. This article describes these broadcasts, the listeners’ role, and the outcomes of the series. It situates them in the context of the BBC’s adult education provision, and examines their educational and scientific contributions. Although the broadcasts were considered successful, they were short-lived. The article investigates reasons for this. It also looks at the reasons for the demise of inter-war adult education provision at the BBC during the later 1930s.     

Contributions from citizen science to science education: an examination of a biodiversity citizen science project with schools in Central Europe

ABSTRACT

Despite the rising popularity of Citizen Science (CS) projects, there is little empirical evidence for effects on learning outcomes, particularly when young people are involved. It is also often not clear how CS projects are linked to science education (SE) research. The aim of this study was to examine biodiversity CS projects in an outdoor school class context and to measure the effects on individual learning outcomes (ILOs) with a perspective for SE. Five learning outcomes considered important for CS were tested: interest, self-efficacy/mastery, motivation, behaviour and attitude. These ILOs were measured via eight different scales and tested in an evaluation study of a large CS project with 428 students aged 8–18. Students recorded hedgehogs, wild bee activity, birds and butterflies in gardens. Results showed that students’ interest and motivation, as well as perceived mastery increased during the project. Most remarkably, positive attitudes towards wild animals, natural gardens and biodiversity rose significantly. For most ILOs there were significant differences between age groups: Primary school students showed the highest ILOs and also provided most database entries. The authors describe how well biodiversity CS projects contribute to SE aims and how discrepancies between educational and scientific aims in CS projects may be addressed.     

Students' self-efficacy for science in different school systems

The important role of self-efficacy (SE) in students' motivation, engagement, persistence, and academic achievements has been reconfirmed by ample research, both in general and for STEM disciplines. As most studies focused on traditional school systems, additional research is needed on how science SE develops in different educational environments, which was the goal of this study. Data were collected from 1979 students in Grades 5–9 from 19 traditional, Waldorf, and democratic schools in Israel. Students completed a questionnaire that assessed their science self-efficacy (SSE), general and academic self-efficacy (GASE), and the sources of their SSE: teachers', parents', and peers' social persuasions, vicarious experiences and mastery experiences. Results revealed that SSE and GASE differed in their levels and in the way they changed with grade. These differences, and variations in the roles of the various sources of SSE, appeared to be influenced by the schools' cultures and curricula. Quantitative results are accompanied by verbal illustrative examples from interviews with students and teachers.     

The use of organising purposes in science instruction as a scaffolding mechanism to support progressions: a study of talk in two primary science classrooms

Purpose: This study examines how different purposes can support teachers in their work with progressions as a part of a teaching sequences in science in primary school.

Design/Method: The study was carried out in two classes working with inquiry and the events that took place in the classroom were filmed. In the study, we have chosen to use the technical term proximate purposes for the student-oriented purposes, and ultimate purposes for the scientific purposes. Together, these two types of purposes form the organisational purposes for the classes. Proximate purposes work in such a way that students can use their language and relate to their experiences as ends-in-view. To examine how organising purposes can be used to analyse progressions, we discuss examples from two different lessons.

Result: The study shows the importance of proximate purposes working as ends-in-view and also demonstrates how the teacher and students may create continuity in teaching to enable progression as a part of a teaching sequence.

Conclusions: To create continuity, it was essential that the teacher scaffolded the students in ways which allowed the students to explicitly differentiate between what was relevant or not, about the proximate purposes in relation to the ultimate purpose.     

Learning science in an alternative context: The effects on a selected group of young science educators

The Ontario Science Centre is a popular alternative learning environment for science and technology. Using semi-structured interviews, the research underpinning this paper investigates the experiences and effects of working as a Host or exhibit interpreter at the Science Centre. It examines how the Hosts benefit from the program in terms of their knowledge about and attitudes toward science and technology. What is distinctive about learning in this context, and its implications for science and technology education in schools, are discussed. The dominant aspects of learning for the respondents tended to be inspirational and attitudinal, as well as cognitive. The comments of the respondents indicate that in order to encourage learning in science and technology, science education needs to focus on more than a narrow concern with curriculum content.     

Engaged food science: Connecting K‐8 learners to food science while engaging graduate students in science communication

Connecting the public to concepts in science, technology, engineering, and mathematics (STEM) is an essential for technological advancement and inspiring future scientists, impacting both the communicator and the audience's understanding of scientific topics. Without proper communication of scientific knowledge, acceptance and implementation of new technologies can be hindered. Additionally, increasing public awareness about current scientific issues through STEM engagement permits more informed policy and consumer choices, especially in the field of food science where many new food technologies are met with initial resistance by the consuming public. Here, we describe an event that introduced topics in food science to the nonexpert public, including K‐8th grade participants and their adult caregivers in an informal learning environment. This program consists of six activities that collectively introduce three areas in food science: food chemistry, food microbiology, and process engineering. Protocols are provided for each activity including a materials list (with the option to scale up or down according to event duration, event space allowances, and number of participants), learning objectives and discussion points that are adaptable to different age groups, event spaces, or budgets. Each activity has a participatory component to ensure both audience member and instructor engagement. A program designed for food science communication empowers young scientific minds to better understand complex scientific topics and could inspire them to envision a possible career in STEM fields, with the additional benefit of providing graduate students an exciting medium through which they may practice their science communication skills, potentially benefiting not only their personal academic and professional skills but also broader societal needs.     

Priming urban learners' attitudes toward the relevancy of science: A mixed-methods study testing the importance of context

The development of three-dimensional learning among all K-12 student demographics remains a prominent goal for the field of science education. However, substantial research in science teacher education for urban populations showcases hurdles to overcome in order to achieve this goal, particularly for elementary teachers. Research shows that urban elementary teachers are often ill-prepared to develop a type of science pedagogy responsive to students' learning needs. The fidelity of such pedagogies that these teachers adhere to when trying to implement such a requested content–relationality between these populations and how their local contexts can be used as sites to learn science in relevant ways are often not fully realized, as well. Given that science achievement gaps exhibit racial disparities starting in primary grades and attitudes toward science have been shown to affect academic achievement and motivation, we argue that one way to ameliorate, in at least an incremental way, this disparity is to design novel learning experiences to prime students to see the relevancy of science in their local contexts before such three-dimensional designed learning is set to occur. In this research, we leveraged the immersive nature of Virtual Reality 360 videos and present a design-based research iteration testing how this novel technologically enhanced learning experience may have influenced close to 400 urban elementary students' attitudes toward science around those attitudes labeled as “behavioral beliefs” by the field. Using a concurrent, convergent mixed-methods design with a two-way multivariate analysis of covariance quantitative data set triangulated with students' qualitative self-reports that were transformed into quantitative preponderances in graphic form, the data support that our design iteration emphasizing the importance of context as a design focus can prime students who struggle to see science as relevant to change their attitudes. Implications are discussed around relationality, novel technological affordances, and the use of local contexts as learning resources.     

Exploring mentoring in the context of team science

Despite increased research into team science and collaboration, little is known about postdoctoral scholars’ pathways to becoming independent researchers, particularly as it relates to the mentoring relationship. The purpose of our study was to explore if and how the team science framework promotes collaboration and the development of independent researchers from mentees’ and mentors’ perspectives. A convenience sample of faculty mentors and postdoctoral mentees, participated in semi-structured interviews. The analysis revealed three themes for the mentees: working with others, evaluating mentoring, exploring resources, and five themes for the mentors: elaborating on scholarly productivity, mentoring style, setting team culture, strategies to develop T32 scholars, and evaluating program qualities. The findings showed that scholars were engaged in an atmosphere of collaboration fostered by their mentors and that mentors encouraged scholars’ capacity for scientific thinking. Future studies should acquire the perspectives of all team members to examine how teams function.     

The impact of scienceware and foundations on students' attitudes towards science and science classes

In this paper, we describe changes in students' ideas about science classes, attitudes about science, and motivations for studying science, in a classroom designed to support projectbased science learing. Using a survey designed to provide a measure of students' attitudes towards science classes and science, we have compared students enrolled in a traditional high school biology course, with students enrolled in an integrated, project-based science course called Foundations I. Survey responses were analyzed to look at differences between and within two groups of students over the course of one school year. In general, the results of this study suggest that providing students with opportunities to collect and analyze their own data in science classes results in a change in students' ideas about science classrooms. Foundations I students' increased tendency to agree with statements about using information, drawing conclusions, and thinking about problems, implies a change in their understanding of what it means to do science in school. These students, in contrast to students in the traditional Biology course, no longer describe their science experience as one of memorization, textbook reading, and test taking. Instead they see science class as a place in which they can collect data, draw conclusions, and formulate and solve problems.

对中国语境下“科学挤压人文”命题的审思

在中国语境下,"科学挤压人文"这一命题并不必然成立。在中国,人文传统的断裂以及由此而来的人文教育的空疏化、政治化是人文精神失落不可忽视的内在原因,而20世纪80年代以后政治权力合法性基础的转移所导致的经济功利主义的强旺是其失落的外部诱因。     

Standardized test outcomes for students engaged in inquiry‐based science curricula in the context of urban reform

Considerable effort has been made over the past decade to address the needs of learners in large urban districts through scaleable reform initiatives. We examine the effects of a multifaceted scaling reform that focuses on supporting standards based science teaching in urban middle schools. The effort was one component of a systemic reform effort in the Detroit Public Schools, and was centered on highly specified and developed project‐based inquiry science units supported by aligned professional development and learning technologies. Two cohorts of 7th and 8th graders that participated in the project units are compared with the remainder of the district population, using results from the high‐stakes state standardized test in science. Both the initial and scaled up cohorts show increases in science content understanding and process skills over their peers, and significantly higher pass rates on the statewide test. The relative gains occur up to a year and a half after participation in the curriculum, and show little attenuation with in the second cohort when scaling occurred and the number of teachers involved increased. The effect of participation in units at different grade levels is independent and cumulative, with higher levels of participation associated with similarly higher achievement scores. Examination of results by gender reveals that the curriculum effort succeeds in reducing the gender gap in achievement experienced by urban African‐American boys. These findings demonstrate that standards‐based, inquiry science curriculum can lead to standardized achievement test gains in historically underserved urban students, when the curriculum is highly specified, developed, and aligned with professional development and administrative support. © 2008 Wiley Periodicals, Inc.

Promoting science and technology in primary education: a review of integrated curricula

Integrated curricula seem promising for the increase of attention on science and technology in primary education. A clear picture of the advantages and disadvantages of integration efforts could help curriculum innovation. This review has focused on integrated curricula in primary education from 1994 to 2011. The integrated curricula were categorised according to a taxonomy of integration types synthesised from the literature. The characteristics that we deemed important were related to learning outcomes and success/fail factors. A focus group was formed to facilitate the process of analysis and to test tentative conclusions. We concluded that the levels in our taxonomy were linked to (a) student knowledge and skills, the enthusiasm generated among students and teachers, and the teacher commitment that was generated; and (b) the teacher commitment needed, the duration of the innovation effort, the volume and comprehensiveness of required teacher professional development, the necessary teacher support and the effort needed to overcome tensions with standard curricula. Almost all projects were effective in increasing the time spent on science at school. Our model resolves Czerniac’s definition problem of integrating curricula in a productive manner, and it forms a practical basis for decision-making by making clear what is needed and what output can be expected when plans are being formulated to implement integrated education.     

Information Communication Technology (ICT) integration in a science education unit for preservice science teachers; students' perceptions of their ICT skills, knowledge and pedagogy

There is an expectation that new science teachers will be able to effectively use a range of information communication technology (ICT) related resources inthe science classroom in order to enhance student learning. All school systems in Australia are in the process of providing teachers with ICT professional development and infrastructure. This paper outlines a range of initiatives designed to integrate ICT in a compulsory science education unit for students enrolled in a Graduate Diploma in Secondary Education. An action research model based on constructivist principles was used to evaluate the effectiveness of modelling, open-ended co-operative group activities and authentic assessment in enabling students to enhance their ICT skills, knowledge and pedagogical content knowledge in a science education context. Multiple sources of data were generated including a pre and post unit questionnaire that was analysed using Rasch modelling. The questionnaire determined students' perceptions of their preparedness to teach using ICT. The findings of this research suggest that some skills warranted greater attention in the unit, but students' pedagogical knowledge and knowledge and critique of ICT resources were enhanced over the duration of the unit.     

Learning in context: Technology integration in a teacher preparation program informed by situated learning theory

This investigation explores the effectiveness of a teacher preparation program aligned with situated learning theory on preservice science teachers' use of technology during their student teaching experiences. Participants included 26 preservice science teachers enrolled in a 2‐year Master of Teaching program. A specific program goal was to prepare teachers to use technology to support reform‐based science instruction. To this end, the program integrated technology instruction across five courses and situated this instruction within the context of learning and teaching science. A variety of data sources were used to characterize the participants' intentions and instructional practices, including classroom observations, lesson plans, interviews, and written reflections. Data analysis followed a constant comparative process with the goal of describing if, how, and why the participants integrated technology into their instruction and the extent to which they applied, adapted, and innovated upon what they learned in the science teacher preparation program. Results indicate that all participants used technology throughout their student teaching for reform‐based science instruction. Additionally, they used digital images, videos, animations, and simulations to teach process skills, support inquiry instruction, and to enhance student engagement in ways that represented application, adaptation, and innovation upon what they learned in the science teaching methods program. Participants cited several features of the science teacher preparation program that helped them to effectively integrate technology into their instruction. These included participating in science lessons in which technology was modeled in the context of specific instructional approaches, collaborating with peers, and opportunities for feedback and reflection after teaching lessons. The findings of this study suggest that situated learning theory may provide an effective structure for preparing preservice teachers to integrate technology in ways that support reform‐based instruction. © 2013 Wiley Periodicals, Inc.

Mathematics and science inequalities in the United Kingdom: when elitism,sexism and culture collide

An examination of gender, social class and ethnicity performance and participation patterns in different UK countries shows that inequities occur in relation to gender, class and ethnicity but that the patterns of inequity look quite different in the three domains. Achievement is equal for different genders but many more males take mathematics forward to advanced levels; social class differences persist in both achievement and participation; and ethnicity shows a varied pattern with some groups performing and participating at particularly high levels and some particularly low. This paper identifies some critical issues that we face in making mathematics and science equitable and begins to analyse some of the barriers that stand in the way of students who are female, and from some ethnic and social groups.
