Visualization and its role in students’ assessment of scientific explanations

It is argued that an important first stage in students’ assessment of scientific explanations is that of visualization. A test of visualization is developed and the results for students in their first year of university education are presented. Certain characteristics of defective visualization and the circumstances in which blocks to satisfactory explanation assessment are created emerge rather clearly.

     

The epistemic role of novel metaphors in teachers’ knowledge constructions of school reform

In this article, a parallel is drawn between Steven Hawking’s use of common and novel metaphors in his evolving explanation of the theory of the universe and the similar use of common and novel metaphors by educators in four school contexts attempting to illuminate their experiences of school reform storied and restoried over time. The epistemic role of novel metaphors is unpacked through examining the plotlines of the metaphors, the morals of the metaphors, the freedom of the metaphors and the teacher knowledge implications resident in the live metaphorical utterances. Through the use of self‐selected novel metaphors, both Hawking and the educators merged propositional and non‐propositional knowledge that was bound up in persons—and communicated across people—in deceptively simple, though infinitely complex, ways.     

The case of high motivation and low achievement in science: what is the role of students’ epistemic beliefs?

The importance of motivation-related factors in shaping students’ academic achievement across a range of areas, including science, has been consistently acknowledged by the existing research literature. In an effort to improve students’ science achievement, many education systems put particular emphasis on the enhancement of intrinsic (i.e. enjoyment and interest) and instrumental motivation in the subject. However, based on the latest Programme for International Student Assessment (PISA) data, many of the countries that managed to increase their motivation indices between 2006 and 2015 did not necessarily note a rise in science performance, with many still performing below the Organisation for Economic Co-operation and Development (OECD) average. Interestingly, although students’ motivation increased in some of these countries (e.g. Luxembourg, Iceland and Greece), their average performance in science decreased. Using the PISA 2015 data for Greece, this study examined the case of high motivation and low achievement in science by incorporating epistemic beliefs in the discussion. The multilevel analysis confirmed the importance of 15-year-old students’ motivation for learning science in predicting their science achievement and highlighted the positive predictive power of their epistemic beliefs. Policy and practice recommendations are provided based on the study findings, stressing the key role of students’ epistemic beliefs.     

The catcher in the lie: The role of emotions and epistemic judgments in changing students’ misconceptions and attitudes in a post-truth era

We extend previous theoretical and empirical work by examining the role that emotions and epistemic judgments play when learning from different refutation plus persuasive and expository plus persuasive texts. We examined how variations in messages designed to change misconceptions and attitudes about genetically modified foods (GMFs) might differentially impact the extent to which individuals engage in epistemic judgments; the emotions individuals experience during learning; and, how epistemic judgments and emotions might facilitate or constrain conceptual and attitudinal change. One hundred twenty-five undergraduate university students were randomly assigned to one of four text conditions: refutation plus positive persuasive text, refutation plus negative persuasive text, expository plus positive persuasive text, or expository plus negative persuasive text. Students were asked to think and emote out loud during learning to capture epistemic judgments and emotions as they occurred in real time. After the learning session, students also self-reported the emotions they experienced during learning. Results revealed that students who were given positive persuasive texts experienced more positive emotions (both intensity and frequency) during learning, whereas those who were given negative persuasive texts experienced more negative emotions (frequency) during learning. Students who were given positive persuasive texts engaged in more epistemic judgments and changed more misconceptions about GMFs compared to students in the other three text conditions. Finally, epistemic judgments were significant positive predictors of conceptual and attitudinal change, and both positive emotions and negative emotions predicted attitudinal change. Implications for theories of conceptual and attitudinal change are discussed.     

Why do learners who draw perform well? Investigating the role of visualization,generation and externalization in learner-generated drawing

In two experiments, we investigated which of the factors generation, visualization, and externalization mainly contribute to the benefits of learner-generated drawing. We also examined whether benefits of drawing were more pronounced in delayed rather than in immediate testing. To this end, Experiment 1 (N = 121) focused on the comparison of the factors visualization and generation, whereas Experiment 2 (N = 204) focused on the role of externalization in generative learning activities. In both experiments, participants were asked to read an expository text about biomechanics in human swimming behavior. In Experiment 1, participants were instructed either to construct drawings, to write summaries, to learn with multimedia material, or to only read. In Experiment 2, participants were instructed either to construct drawings, to mentally imagine the content, or to observe a multimedia presentation evolving gradually. Learning outcomes were measured with a recognition, transfer, and drawing test. In Experiment 1, the tests were administered immediately and after one week (within-subjects), whereas in Experiment 2 time of testing was manipulated between subjects. The results of both experiments revealed effects of experimental conditions for transfer and drawing performance, but not for recognition performance. Taken together, the findings indicate that visualization and externalization are the main contributing factors: The drawing and multimedia conditions outperformed the summary and text-only conditions (Exp. 1), thereby supporting the role of visualization, whereas the drawing and observation conditions outperformed the imagery conditions on the drawing test (Exp. 2), thereby emphasizing the role of externalization. There is little evidence that drawing constitutes a desirable difficulty.     

Support for self-regulation in learning complex topics from multimedia explanations: do learners need extensive or minimal support?

Acquiring complex conceptual knowledge requires learners to self-regulate their learning by planning, monitoring, and adjusting the process but they find it difficult to do so. In one experiment, we examined whether learners need broad systems of support for self-regulation or whether they are also able to learn with more economical support configurations. Eighty-six undergraduate students with little prior domain knowledge learned plate tectonics from a multimedia presentation involving animation with concurrent narration and support in one of four forms: minimal support, two variants of intermediate support, or extensive support. After the presentation, participants solved retention and transfer tests. The results revealed that participants receiving the broadest system of support outperformed those in the other conditions, which did not differ from one another. This means that it is so difficult for learners to self-regulate learning that they need considerable support if they are to learn complex conceptual knowledge.     

Which cognitive processes support learning during small-group discussion? The role of providing explanations and listening to others

Seventy students participated in an experiment to measure the effects of either providing explanations or listening during small group discussions on recall of related subject-matter studied after the discussion. They watched a video of a small group discussing a problem. In the first experimental condition, the video was stopped at various points in time, enabling the participants to verbally respond to the discussion. In the second condition, they listened to the same discussion, without contributing. In the control condition, they listened to a discussion that was not related to the subject-matter subsequently studied. After the discussion, all participants studied a text and answered questions that tested their recall of information from this text. No immediate differences in recall were found. One month later, participants who had actively engaged in explaining remembered more from the text. The conclusion appears justified that actively providing explanations during a discussion positively affects long-term memory.     

The role of external experts’ intervention in higher education institutions for radical change

This paper focuses on the way lecturers observe, feel restrained by and cope with quality management systems that have been implemented in the higher education systems of the United Kingdom and the Netherlands. As two sides of the same coin, quality enhancement and quality control are of increased significance in European Higher Educaction Institutions (HEIs), particularly through the Bologna Process. We are interested in the way that both enhancement and control blend into the current systems, and we are concerned for too much dominance of control, as has been suggested in recent managerial literature. Analysis of 40 interviews in both countries among researchers and lecturers in traditional and universities of applied sciences showed many similarities. It is not so much the general idea of quality management that is being turned down by the respondents. They see the benefits quite clearly. Still, the general belief is that quality management in its current shape and character does not fit with the work of the individual academic, neither their teaching nor their research. The respondents worry for and resent the consequences of increased emphasis on quality assurance and control. The developments concerning the quality management of their HEIs are perceived in terms of quality assurance by the UK respondents. Instead, the Dutch are more occupied with finding ways to “how to deal with” such developments.     

The mediating role of teacher self-efficacy in the relation between teacher–child race mismatch and conflict

The far-reaching impacts of the teacher–child relationship, including academic achievement and social/behavioral adjustment, have been well-documented. At the same time, literature also suggests that teacher perceptions of teacher–child relationships are impacted by the race/ethnicity match or mismatch between teacher and child, with matching related to more positive teacher perceptions. However, limited work has focused on children who are at-risk for emotional and behavioral disorders (EBDs) or tested the mechanisms that mediate the relation between a mismatch in the race and teacher-perceived conflict. Thus, the current study used multilevel structural equation modeling to test whether a higher proportion of race mismatch between children in the classroom with problem behavior and teachers was related to teachers' classroom management self-efficacy and, in turn, teacher-perceived conflict with children among 148 teachers and 354 preschool-aged children. Results indicated that among students most at-risk for EBDs, a higher proportion of race mismatch between teachers and children significantly predicted less teacher classroom management self-efficacy and, in turn, significantly predicted teachers' greater perceived conflict with children. Furthermore, this mediation pathway was significant. Findings highlight the importance of teacher training and support that focused on increasing self-efficacy to improve relationships between teachers and children.     

Why do people accept environmental policies? The prospects of higher education and changes in norms,beliefs and policy preferences

Pressing problems of environmental degradation are typically argued to require coordination, primarily through state intervention. Social scientists are struggling to understand how attitudes toward such state interventions are formed, and several drivers have been suggested, including education. People with university degrees are assumed to have certain values as well as the analytical skills to understand complex issues such as climate change. By using a unique panel data-set with students in different university programs (economics, law and political science), this study provides a better understanding of whether and how education affects environmental policy acceptance. One important finding is that university studies generate variation in support and scepticism toward different types of policy measures. For example, economics students tend to develop more positive attitudes toward market-based policy measures. This indicates a potential for education to increase the societal support often hindering the implementation of such policy tools.     

What do they like? Communication preferences and patterns of older adults in the United States: The role of technology

ABSTRACT

With the development of information and communication technologies (ICTs), there are increasingly more Internet-based communication methods available for older adults besides traditional methods (e.g., in-person or landline phone). However, older adults’ preferred communication methods remain under-investigated. The purpose of this study is to explore the communication preferences and patterns of older adults in the United States, with emphasis on technologically-mediated environments. In this study, 17 semistructured interviews were conducted with participants from a midwestern state in the United States. The goal was to examine older adults’ communication patterns and preferences with family members and friends, as well as their views about the impacts of modern technology on communication. Three themes (communication preferences and reasons, communication barriers, and the impacts of technology) were generated from the interviews. The findings showed that although face-to-face communication is the most preferred method, telephone communication is the most commonly adopted method. Interviewees also shared different opinions regarding Internet-based communication. The current study illustrated the importance of understanding the preferences and patterns of older adults’ communication needs and desires.     

“Why do dogs pant?”: Characteristics of parental explanations about science predict children's knowledge

Using a new method for examining parental explanations in a laboratory setting, the prompted explanation task, this study examines how characteristics of parental explanations about biology relate to children's knowledge. Parents (N = 148; M_age = 38; 84% female, 16% male; 67% having completed college) of children ages 7–10 (M_age = 8.92; 47% female, 53% male; 58% White, 9.5% Black, 9.5% Asian) provided answers to eight how and why questions about biology. Parents used a number of different approaches to address the questions, including providing more mechanistic responses to how questions and more teleological responses to why questions. The characteristics of parental explanations—most notably, how frequently parents provided correct responses—predicted children's performance on measures of verbal intelligence and biological knowledge. Additional exploratory analyses and implications for children's learning are discussed.     

Why do women value credentials? Perceptions of gender inequality and credentialism in South Korea

This mixed methods study investigates how perceptions of gender inequality can positively predict credentialist attitudes and beliefs for women based on a survey of 488 college students from six universities with an approximately equal proportion of men and women, and follow-up interviews with 18 of these respondents in 2018-19. 11 men and 7 women were interviewed. The findings suggest that women are more likely to value credentials in the face of discrimination at work because they believed credentials could help them overcome their gender disadvantage, catch up with men, and minimize their risk of failure, as education was perceived to provide equal opportunities for men and women.     

When peers agree,do students listen? The central role of feedback quality and feedback frequency in determining uptake of feedback

Prior research on the complex process of revision based upon peer feedback has focused on characteristics of each piece of feedback in isolation. Multipeer feedback allows for feedback to be repeated (or not), which could be a signal of feedback quality or be especially persuasive to peers. Separately, little research has examined how well peers select more impactful and accurate peer feedback in their revisions, whether repeated or not. We analyzed almost 2,000 peer comments received by 107 students in a secondary writing course in the US to determine whether feedback quality and feedback frequency predicted feedback implementation. Controlling for other feedback features and context factors, students were much more likely to implement feedback as both feedback quality and feedback frequency increased, surprisingly with no interaction (i.e., even low-quality comments were more likely to be implemented when repeated). However, low-quality comments often partially overlapped with high-quality comments, providing a potential explanation for the lack of an interaction. Finally, consideration of feedback frequency and feedback quality provides new insights into which feedback features are actually related to implementation. The results generally allay concerns about the blind-leading-the-blind in peer feedback as well as pushing for peer feedback arrangements that produce more overlapping comments.     

The role of language and learning models in student-directed CALL

The development of CALL has been accompanied by a debate about which theoretical foundations it should be built upon. This paper will ask what the relationship between CALL and models of language and learning has been, and consider what it should be. Research undertaken using ICT in order to identify issues relevant to second language acquisition (SLA)will be examined, and its implications noted. The application of interactionalist models of SLA will be considered and the contribution that task-based language learning could make to CALL investigated. The concept of "student-directed" CALL is used in order to distinguish the SLA-based interactionalist models proposed from the many CALL approaches based on gap fills, drilling, etc. and from the many tutor-led programmes in areas such as EAP.

Local and global – conflicting perspectives? The place of overseas practicum in preservice teacher education

International practicum is disappearing from teacher education programs with the increasing pressures for ‘local experience’. International practicum is seen as too different from local contexts to develop preservice teachers to meet professional standards. This study explores the teaching development of a group of 24 preservice teachers from a regional university on a placement in Beijing and examines the ways they make explicit connections between their learning on overseas practicum and their teaching in Australia. The findings indicate that it is precisely the difference in teaching contexts that enables professional development in key areas of professional standards. The study challenges perceptions of overseas practicum as ‘cultural tourism’ and also the presumption of conflict between preparing teachers for both global and local contexts.
