Intuitive Theory

Constructing an intuitive theory from data confronts learners with a “chicken-and-egg” problem: the laws can only be expressed in terms of the theory’s core concepts, but these concepts are only meaningful in terms of the role they play in the theory’s laws; how can a learner discover appropriate concepts and laws simultaneously, knowing neither to begin with? We explore how children can solve this chicken-and-egg problem in the domain of magnetism, drawing on perspectives from computational modeling and behavioral experiments. We present four- and five-year-olds with two different simplified magnet-learning tasks. Children appropriately constrain their beliefs to two hypotheses following ambiguous but informative evidence. Following a critical intervention they learn the correct theory. In the second study, children infer the correct number of categories given no information about the possible causal laws. Children’s hypotheses in these tasks are explained as rational inferences within a Bayesian computational framework.

Understanding and being able to measure, analyze, compare, and contrast the image of a tourism destination, also known as tourism destination image (TDI), is critical in tourism management and destination marketing. Although various methodologies have been developed, a consistent, reliable, and scalable method for measuring TDI is still unavailable. This study aims to address the challenge by proposing a framework for a holistic measure of TDI in four dimensions, including popularity, sentiment, time, and location. A structural model for TDI measurement that covers various aspects of a tourism destination is developed. TDI is then measured by a comprehensive computational framework that can analyze complex textual and visual data on a large scale. A case study using more than 30,000 images, and 10,000 comments in relation to three tourism destinations in Australia demonstrates the effectiveness of the proposed framework.

The key issue of this current study is related to shaping the attractiveness of heritage destinations, highlighting the significance of reuse and upgrading their historical buildings to achieve a high level of competitiveness and distinctiveness through a smart approach. Some of these cultural assets and events tend to be monotonous, and not so attractive for various categories of tourists, which negatively affects investment opportunities, tourism development, and social and economic resources. Furthermore, previous works have criticized the lack of evidence to support that the structure contains critical attributes and measurement items linked to the competitiveness of smart heritage destinations. As a result, this study aims to design and develop a composite index for evaluating these destinations and their buildings, which includes nine dimensions (attributes) and a set of key performance indicators (KPIs) of intelligent performance and competitiveness, reflecting the combination and noticing the distinct perspective between them. A mixed-methods approach was used between qualitative and quantitative methods to perform content validation on the proposed index. Furthermore, a pilot study was implemented for tourism heritage destinations to improve the quality and efficiency of the proposed index. Then, exploratory factor analysis (EFA) was used to analyze the data to develop the proposed index and measure its validity and reliability. Finally, the proposed composite index was finalized with 139 KPIs and applied to a case study (Salah El-Din Citadel). After that, we validated its utility in providing a quantitative evaluation of this heritage destination, identifying critical intervention priorities, and determining dimensions that need to be restructured. Additionally, it highlighted recommendations for future improvements to strengthen these heritage destinations to become smart heritage destinations capable of competition in the tourism sector.

Constructing Knowledge

The use of small collaborative learning teams in STEM classrooms is not new to the field of education. At the undergraduate level, evidence continues to accumulate that organizing students into groups in which they engage in knowledge construction by completing active learning tasks is an effective means to achieve student-learning objectives. However, this teaching method is rarely used by postsecondary faculty, especially in large-enrollment classes. An argument for the efficacy of this method is presented in three parts. This chapter first outlines the theoretical basis for collaborative group learning. Grounded in the literature, this theory is then translated into practice by discussing evidence-based advantages and challenges to creating collaborative learning environments. The chapter concludes with a discussion of a case study examining how the first author has implemented this method of collaborative instruction with a unique means of structuring groups within a large-enrollment non-majors biology classroom.

Teachers Perspectives

PurposeThe purpose of this paper is to explore perspectives of secondary (9–12) teachers on how to sustain growth mindset concepts within instructional practices as well as identifying barriers to sustainment.Design/methodology/approachThis study employed an exploratory case study to obtain the lived experiences of participants. An inductive analysis process was utilized on the data collected through structured interviews and a semi-structured focus group.FindingsFour major themes emerged from an in-depth analysis process: embed growth mindset practices in daily classroom instruction, communicate verbal affirmations and implement growth mindset learning tasks, allow students to experience academic successes and failures and teachers should receive continual support.Research limitations/implicationsThe study was limited to secondary grades (9–12). Therefore, it is recommended to expand the study to grades K-8.Originality/valueDue to a gap in the literature, this study provided insights into sustaining an innovative psychological approach, growth mindset, within academic instruction. Growth mindset concepts have been supported through the work of seminal researcher Carol Dweck and other prevalent educational researchers (e.g. Robert Marzano) to provide teachers with effective classroom instructional practices that can academically progress students.

The introduction frames the book as a critical intervention in the current debate about the role of alternative grassroots models in modernizing mainstream political and economic structures. After framing the political and theoretical issues at stake in New Orleans’s cooperative movement, the introduction outlines how historical local cooperatives interact with transnational cooperative principles to improve their community, expand opportunities for civic participation, and reform systems of governance. Each chapter’s case study represents consumer, producer, or distribution cooperatives that manifest different visions of ideal capital-worker relations and are inspired by local and international utopian socialist, Rochdale, and hybrid racial justice cooperative models. Each example is constitutive of black, working-class, female, and immigrant residents particular subject positions and economic needs. Consequently, the book articulates and debates citizens relationship the state, an ideological drama that plays out in the city’s social spaces to either propel or retard larger challenges to capitalism.

Core Concepts

In this introductory chapter, we present our understanding of the core concepts of this book, namely social innovation and poverty, and situate these concepts in contemporary debates on the governance of welfare provision. We define social innovation as actions that satisfy social needs through the transformation of social relations, which crucially implies an increase of the capabilities and access to resources of people living in poverty. Poverty is not reduced to a lack of monetary income, but refers to a range of processes of social exclusion in various spheres of life that hinders people’s full participation in society. We outline the aim of this book as a sustained attempt to analyse how the social innovation dynamics of localised initiatives are shaped by the welfare regime context with its specific spatial and institutional characteristics. Finally, we discuss the methodological strategy of the comparative case study research on which this book is based.

Critical Intervention

A History of the Case Study represents a critical intervention into contemporary debate concerning the construction of knowledge which – after Michel Foucault’s elaborations on modern discourses of power – considers the medical case study in particular as an expression of new forms of disciplinary authority. This volume scrutinises the changing status of the human case study, that is, the medical, legal or literary case study that places an individual at its centre. With close reference to the dawning of ‘sexual modernity’ during the nineteenth and twentieth centuries, and to ideas about sexual identity in the period immediately before and after the fin de siècle, the following chapters examine the case writing practices of selected pioneers of the case study genre....
