Human origins have been debated by evolutionists and creationists. Christian young adults are educated first on creationism and learn of evolution later. This delayed education of evolution leads to potential belief change and stress. This belief change process may be similar to Berry’s acculturation. After belief change, individuals may exhibit belief bias during human origin argument evaluation. Little research has been done to explore a formal belief change model and belief bias in human origin argument evaluation. Data was collected from 121 PSYC 102 and MTurk participants in an online survey measuring evolution and creationist beliefs. Vignettes presented evidence for creationism and evolution. This evidence was evaluated by participants. Cluster analyses, MANOVAs, and ANOVAs were used to determine statistical significance. Results found three groups of individuals exist and these groups differed on age of exposure to evolution and belief change stress measures. These groups evaluated creationism and evolution evidence differently exhibiting belief bias during argument evaluation. These results expand current literature by finding a potential belief change model and preliminary evidence to support earlier teaching of evolution in schools. Limitations include violated statistical assumptions and forced clusters. Further research is needed to explore these three groups in more detail.

Since the early days of psychology, practitioners have recognised that metacognition - or the act of thinking about one's own thinking - is intertwined with our experience of the world. In the last decade, scientists have started to understand metacognitive signals, like judgments of confidence, as precise mathematical constructs. Confidence can be conceived of as an internal estimate of the probability of being correct. As such, confidence influences both advice seeking and advice taking while allowing people to optimally combine their views for joint action and group coordination. This work begins by exploring the idea that confidence judgments are important for monitoring not only uncertainty associated with one's performance but also, thanks to their positive covariation with accuracy, the reliability of social advisers, particularly when objective criteria are not available. I present data showing that, when adviser and advisee's judgments are independent, people are able to detect subtle variations in advice information, irrespective of feedback presence. I also show that, when such independence is broken, the use of subjective confidence to track others' reliability leads to systematic deviations. I then proceed to explore the differences existing between static and dynamic social information exchange. Traditionally, social and organisational psychology have investigated one-step unidirectional information systems, but many real-life interactions happen on a continuous time-scale, where social exchanges are recursive and dynamic. I present results indicating that the dynamics of social information exchange (recursive vs. one-step) affect individual opinions over and above the information that is communicated. Overall, my results suggest a bidirectional involvement of confidence in social inference and information exchange, and highlight the limits of the mechanisms underlying it.

Given the fundamental role beliefs play in guiding what individuals think and do, it is important to understand teachers' beliefs and their development in order to facilitate professional growth, which in turn has the potential to promote effective teaching and learning. While research efforts have been devoted largely to investigating teachers' beliefs, it is surprising that, despite its significance, there is little published data concerning vocabulary teaching, not to mention how professional training contributes to teachers' change in relation to the language area. This thesis, therefore, seeks to investigate teachers' epistemological and pedagogical beliefs about vocabulary development, understand their relationship with actual practice, as well as exploring how they develop through a dialogic approach which emphasises interaction and self-reflection. The study reported herein is situated in the context of Hong Kong, where problems relating to the teaching and learning of English vocabulary have been repeatedly highlighted in the literature. It mainly involves six frontline teachers of English as a second language in a local secondary school selected using purposeful sampling. Of these six teachers, four participated in a teacher development programme which focused on dialogic reflection on beliefs and practices regarding vocabulary teaching, whereas the remaining ones did not. Adopting a case study research strategy, the research draws on four major sources of data, including lesson observations, semi-structured interviews, teachers' professional dialogues and reflective writing, to illuminate issues regarding vocabulary teaching and the process of change. The findings of the study reveal the need to promote teacher professional development regarding vocabulary teaching and develop teachers' awareness of their own and alternative beliefs and practices. They also provide empirical support for the notion that dialogic reflection helps foster teachers' change, and enable us to arrive at a better understanding of the complicated nature of teachers' cognitive and behavioural development. These shed new light on sociocultural theory, generate original insights into how dialogic interaction can be used as a mediational tool to facilitate and understand teacher change in beliefs and practice, as well as providing implications for second language education and teacher professional development.

There is limited research measuring public opinion about the correctional practice of solitary confinement (SC). Given that public opinion can influence policies, it is important to determine whether or not one's beliefs can be updated upon receiving information about the use and effect of SC. Prior research indicates that public opinion is malleable, and thus, may be susceptible to modification. Though, people may be more willing to update their beliefs when the information they receive confirms their existing beliefs (i.e., confirmation bias). This study used an experimental design in which participants were asked to provide their opinions on a series of statements designed to measure their support for SC. Participants were randomly assigned to one of two treatment conditions that provided differing messages about the use of SC through brief, informational videos. Participants were either told that SC is a necessary tool to maintain order within prisons, or that SC is harmful to those who experience it. Following the intervention, participants' support for SC was re-measured and their change in score was calculated. Analyses indicated that participants who received information stating that SC is harmful decreased their support for the practice, while those who received information stating it was necessary increased their support for its use. To test for confirmation bias, participants were presented a survey instrument designed to measure their existing support for punishment. The findings indicate that participants had greater belief changes when presented with disconfirming information. These effects were more pronounced when examining moderating demographic variables. The research and policy implications of this study's findings are discussed.

What students should learn in school and therefore also what teachers should teach is an important issue worldwide. Mathematics teaching (and teaching in other subjects) is often regulated by some form of governing text in a written curriculum communcating a set of standards. Another common mean through which policy is communicated is assessments, which for example can convey policy by communicating desirable outcomes in student learning. A common problem with regulating what teachers do through policy means is that it often is difficult to achieve intended changes. This study investigates the impact of a national reform in Sweden initiated in 1994, introducing mathematical competency goals by communicating them through the national curriculum and national assessments. The study is based on analysis of data obtained from the Swedish Schools Inspectorate (SSI), which conducted a quality review of upper secondary school mathematics teaching. During this quality review, the SSI collected data on a representative sample of 145 upper secondary mathematics teachers through interviews, observations, and surveys. This was done in 2009 and 2010, which means that the reform from a time perspective has had ample time to exert influence on teachers. In the study the data obtained from the SSI was analyzed in order to answer two questions:  have teachers changed their beliefs about the goals of upper secondary school mathematics in line with the intentions of the reform, and why have, or have they not, changed their beliefs about the goals of upper secondary school mathematics in line with the intentions of the reform? In research on teachers’ reception of policy messages, similar to the one introduced in Sweden, it has been found that a common response to these messages is that teachers are positive to the message. However, although positive, teachers have often been found to only adopt superficial properties of the reform while still maintaining a highly traditional view of teaching and the goals of teaching, not consistent with the intentions of the reform. Therefore, the questions in this study were examined by using a model that can explain why teachers, when confronted with a reform message, change their beliefs in profound or superficial ways, or not at all. Through analysis of the SSI-data, measures on constructs of the model were obtained, and with statistical means it was examined whether the model can account for the changes in teachers’ beliefs about the goals of upper secondary school mathematics. The results of the study suggest that the Swedish reform has had a relatively small impact, and that the model can give an explanation to why some Swedish upper secondary teachers of mathematics have changed their beliefs in line with the reform, some have changed them in superficial ways, and some have not changed them in any discernable way. Whether teachers perceive the reform as entailing an important and non-trivial change for them seems to be of utmost importance. The results of this study suggest that if teachers do not perceive this, they will not process the message deeply, which by the results of this study suggest that there is little chance for them to change their beliefs in a profound way. If they however do perceive the message as entailing an important and non-trivial change, this study suggests that chances are greater that teachers will change their beliefs in line with the reform. Teachers’ interest in the subject and their perceptions of the usefulness of the documents communicating the message are then in this study suggested to be important factors influencing whether teachers will process the reform message systematically, which in turn heavily influences whether they will change their beliefs in a profound way. One practical implication, suggested by this study is that when policy communicates a new and non-trivial message with the intention of influencing teachers, it is important that the message is communicated clearly. Such clarity makes it more difficult for a teacher to superficially interpret the message as being in accordance with the teacher’s earlier beliefs, and thus not entail any need for change. However, to attain such clarity of a complex message is not an easy task to accomplish.

Teacher preparation programs invest significant resources to influence the beliefs of preservice teachers, including clinical faculty who mentor preservice teachers during practicum experiences. Despite the work of university personnel to guide preservice teachers' beliefs, their influence wanes once preservice teachers cross the threshold into inservice teaching. New mentors, including mentor teachers, instructional coaches, and administrators take the place of university personnel. This quantitative study examined how the beliefs of 77 novice inservice teachers changed toward reform-based mathematics instruction during their first year of teaching. Of the 77 subjects, 50 were interns and 27 had completed student teaching. Near the end of their first year of teaching, subjects were surveyed for their current beliefs at the time of completing the survey. Their beliefs from the time immediately preceding the beginning of their first year of teaching were measured retrospectively. During their first year, school-based personnel served as their "˜transitional faculty' as they supported the novice teachers' teaching experiences. The novice inservice teachers' perceptions of the transitional faculty's beliefs and support, as well as the alignment of their curriculum materials, were also surveyed. Relationships between changes in the beliefs of the novice inservice teachers and their perceptions of their transitional faculty and curriculum were examined. The overall belief means for novice inservice teachers decreased, the extent of which is statistically significant. Analyses of covariance revealed that the perceived beliefs and support of transitional faculty played a statistically significant role in the belief change of novice inservice teachers, as did their curriculum materials. This study highlights the importance of creating systems to improve mentor selection and training so the work of university personnel is not undone during the novice's first year of teaching.

In belief change, message discrepancy is the difference between the belief position advocated in a message and a message receiver’s initial belief position. Psychological discrepancy is the message discrepancy experienced by the receiver. Existing literature had assumed that a high level of psychological discrepancy discounted the weight of a message, which could make the message less effective. However, there were three alternative assumptions about the role of psychological discrepancy. The problem that this dissertation examined was: Does psychological discrepancy affect the weight of a message only, affect the scale value of the message only, affect neither, or affect both? To find out which of these four assumptions was more plausible, this dissertation derived competing hypotheses based on four mathematical models either through an analytic proof alone or a combination of an analytic proof and a computational approximation. This dissertation tested these hypotheses in an experiment with a 3 (high vs. moderate vs. low message scale value) ´ 3 (high vs. moderate vs. low upper bound) between-subjects design (N = 448 Mechanical Turk workers). The results showed that the weight-discounting model had the most supported hypotheses and fit the data the best, which indicated that psychological discrepancy affected the weight of a message only. This dissertation improves the understanding of the mechanism that leads to the outcomes posited by discrepancy models in persuasion research and provides additional empirical evidence for the scale value constancy assumption in information integration theory. / Media & Communication
