Complex influences of mechanistic knowledge,worldview, and quantitative reasoning on climate change discourse: Evidence for ideologically motivated reasoning among youth

Anthropogenic climate change remains divisive in the United States, where skepticism of the scientific consensus is associated with conservative worldviews, resulting in political polarization. This study considers three hypotheses regarding U.S. polarization over climate change that have emerged from social psychology research and applies them to science education by showing how these hypotheses could relate to adolescents' science learning. We then test each hypothesis within an experimental educational intervention designed to study the influence of worldview, mechanistic knowledge, and quantitative reasoning on students' written arguments about climate change. We used mixed methods to analyze the results of this individually randomized trial with clustering involving 357 participants in grades 9–11 from 5 U.S. sites. Findings show that: (a) exposure to mechanistic knowledge about climate change increased odds of receptivity toward climate change; (b) increasingly conservative worldviews were associated with decreased odds of receptivity; (c) worldview and quantitative reasoning interacted, resulting in an amplified effect of worldview for students with greater quantitative reasoning. Results also suggest that the influence of worldview and mechanistic knowledge on receptivity work independently from one another in our dataset. This study demonstrates the value of teaching mechanistic understandings of climate change, yet also demonstrates the influence of worldview on receptivity to climate change for adolescents, as well as complex interactions between quantitative reasoning (something school science aims to develop) and worldview. It shows that moving the U.S. public toward the scientific consensus is complex and involves confronting ideologically motivated reasoning within science education.     

Educational change in post-conflict contexts: reflections on the South African experience 20 years later

ABSTRACT

Reflecting on South African experience, this paper develops an analytical framework using the work of Henri Lefebvre and Nancy Fraser to understand why socially just arrangements may be so difficult to achieve in post-conflict reconstruction. The paper uses Lefebvre's analytic to trace three sets of entangled practices (perceived–conceived–lived) as evident in education in post-apartheid South Africa in order to illustrate the complexity that is entailed in a particular moment of social reconstruction. Coupled with this approach, It draws on Fraser's analytic to show how the different forms of social injustice and their different remedies (redistribution–recognition–representation) may easily shift and slip in times of complex change. The paper shows that post-conflict reconstruction in education requires a number of different social practices that are not easily orchestrated.     

Two schemes of intellectual development: A comparison of development as defined by william perry and jean piaget

The theories of Jean Piaget and William Perry provide two different theories of intellectual development with several similiarities, but also with critical differences. In this study a comparison was made to determine whether the two theories describe operation of the same mental structures or two fundamentally different aspects of intellectual development. The results, based upon individual interviews of all participants, indicate that the two theories outline different and independent processes for assessing intellectual development.     

A social constructivist assessment process model: how the research literature shows us this could be best practice

Although assessment is acknowledged as vitally important in its effect on students’ approaches to learning, there is much criticism of assessment practice. This paper argues that if a social constructivist approach is applied to the assessment process many of the problems could be overcome. It describes what a social constructivist approach to assessment would look like and gives practical examples, from the research literature, of ways it could be implemented.     

A scholarly approach to solving the feedback dilemma in practice

It is clear from the literature that feedback is potentially the most powerful and potent part of the assessment cycle when it comes to improving further student learning. However, for some time, there has been a growing amount of research evidence that much feedback practice does not fulfil this potential to influence future student learning because it fails in a host of different ways. This dilemma of the disjuncture between theory and practice has been increasingly highlighted by the UK National Student Survey results. This paper uses a model of the assessment process cycle to frame understandings drawn from the literature, and argues that the problem with much current practice resides largely in a failure to effectively engage students with feedback. The paper goes on to explore how best to effectively engage students with assessment feedback, with evidenced examples of feedback strategies that have successfully overcome this problem.     

Voices from Manukau: recruitment and success of traditionally under represented undergraduate groups in New Zealand

This paper describes a research project, “Voices from Manukau”, that investigated the impact of a joint initiative by a university and an institute of technology in New Zealand. The purpose of the initiative was to increase the participation of students traditionally under represented at tertiary-level study, particularly Māori (indigenous people) and individuals from Pacific Island nations. Many of the participants were adults who had not experienced high levels of success during their compulsory period of education and they lived in low socio-economic areas. We found that participation of under-represented groups increased. The “Manukau” students were as successful as other undergraduate students studying at the university. Of particular interest was the high level of success of Māori and Pacific Island students.     

Blood and Bones: The Influence of the Mass Media on Australian Primary School Children’s Understandings of Genes and DNA

Previous research showed that primary school children held several misconceptions about genetics of concern for their future lives. Included were beliefs that genes and DNA are separate substances, with genes causing family resemblance and DNA identifying suspects at crime scenes. Responses to this work ‘blamed’ the mass media for these misunderstandings. This study aimed to determine whether that blame had any foundation by examining the media habits and conceptions about genes and DNA of Australian children. With little prior research considering the influence of entertainment mass media on children’s academically relevant knowledge, this was an exploratory study with a mixed modes design. Data were collected by detailed media questionnaires and face-to-face interviews with 62 children aged 10–12 years, and subjected to content and thematic analysis. Specific mass media examples children reported using were examined for genetics content. Results indicate 5 h/day of media use, mostly television including crime shows, and that children perceived television to be their main source of information about genetics. Most children (89 %) knew DNA, 60 % knew genes, and more was known about uses of DNA outside the body such as crime solving or resolving family relationships than about its biological nature and function. Half believed DNA is only in blood and body parts used for forensics. These concepts paralleled the themes emerging from the media examples. The results indicate that the mass media is a pervasive teacher of children, and that fundamental concepts could be introduced earlier in schools to establish scientific concepts before misconceptions arise.
