The development of data use,data skills,and positive attitude towards data use in a data team intervention for teacher educators

This study focuses on understanding how a participation in a data team develops data skills and data use in individual teacher educators. Five teacher educators collaborated in a data team that used data to solve the problem of student teachers dropping out during their course of study. This study aimed at understanding how teacher educators learn from their participation in the data team. We collected data through interviews, surveys, and a knowledge test, and gained insight into the development of data skills, attitude towards data use, and the teacher educators' data use in daily practice. The results show that the data team members’ data skills and attitudes towards data use changed in different ways during the data team intervention depending on their initial situation, and that overall, their data use for school development increased.

For squad-members only! Why some teachers are more popular to interact with than others in data use

Teacher interactions are seen as a source for teachers’ professional development. To better understand this potential, research is needed into who is consulted in data use. Therefore, this study investigates whether Flemish teachers’ popularity in data use discussions can be attributed to formal aspects of the formal school organization, similarity among teachers, proximity and informal bonds between teachers. A multi method study combining social network analysis and interview data was designed. The results reveal that informal bonds between teachers may not be overlooked in how interactions are formed. Because the participants do not seem to choose the colleagues they interact with for data use purposefully, the potential of these interactions for their professional development is questionable. Future research should invest in examining how conscious teachers are of the knowledge and skills of their colleagues in data use and how this knowledge affects the formation of data use interactions.     

Preparing preservice teachers to be data literate: a Queensland case study

Data driven pedagogy has been introduced into Australian schools over the last decade to improve student learning outcomes, but are teacher educators preparing preservice teachers to be data literate? We used a survey to investigate ready-to-graduate preservice teachers’ beliefs regarding their knowledge and skills in data literacy. Before entering a course on data literacy their belief responses indicated that they had basic data interpretation knowledge, but they were unsure of how to translate that knowledge into the classroom to improve student outcomes. The survey was administered again after a data literacy course, which included a five-week supervised professional experience task of observing data being used in schools to drive pedagogy. The post-course survey responses showed students increased confidence in their ability to interpret and use data, suggesting that a data literacy course linked to the professional experience task improves teachers’ sense of preparedness to use data in the classroom. Keywords: Data literacy; professional learning.     

Teachers’ use of knowledge sources in ‘result meetings’: thin data and thick data use.

In this article, we examine teachers’ use of knowledge sources in meetings where they discuss and formulate initiatives and solutions to develop existing teaching practice based on national test results. While practices of data use have been extensively researched, less attention has been given to the content of data use practices. Analyses of what kind of knowledge sources are used, and how, in discussions about student performance levels and accompanying initiatives to improve teaching can yield important insight into the potential and pitfalls of local data use practices. Based on an analysis of the knowledge sources that Norwegian secondary school teachers draw upon in so-called ‘result meetings’ and of the prognostic frames that teachers initiate, we find that teachers use several knowledge sources and that their data use practices can be characterised as complex and ‘thick’, although the data itself are ‘thin’. However, although teachers draw upon a range of knowledge sources and integrate these when identifying possible solutions, the solutions themselves are often short-term and directed towards improving test results. In order for teachers to ask more fundamental questions regarding existing practices, more attention should be directed towards problem-solving processes and also whether result meetings can provide arenas for complex problem-solving.     

Book review of Personas Mexicanas: Chicano High Schoolers in a Changing Los Angeles

Science Education and Student Diversity: Synthesis and Research Agenda (Lee &; Luykx, in press) analyzes and synthesizes current research on how racial/ethnic, cultural, linguistic, and socioeconomic variability affects science achievement among K-12 students who have traditionally been underserved by the education system. The book begins with science achievement gaps among diverse racial/ethnic and socioeconomic groups. After describing the methodological and other criteria for inclusion of research studies, it summarizes major findings in the literature with regard to the relation of science achievement gaps to science curriculum, instruction, assessment, teacher education, school organization, educational policies, and students' home and community environments. Finally, it proposes a research agenda to strengthen those areas in which the need for a knowledge base is most urgent, as well as those that show promise in establishing a robust knowledge base.

The development of statistical literacy among students: Analyzing messages in media articles with Gal's worry questions

Real-world data are fundamental to modern teaching methodologies that aim to improve statistical knowledge and reasoning in students. Statistical information is encountered in everyday life, such as media articles and involves real-world contexts. However, information could be biased or (mis)represented and students should be concerned about the validity of such articles, as well as the nature and trustworthiness of the evidence presented, while considering alternative interpretations of the findings conveyed to them. Statistics educators could make use of media articles to create opportunities for students to reflect on such (mis)representations and build statistical literacy. The purpose of this article is to show how information and data on the Omicron COVID-19 variant have been (mis)represented in the media and by government entities. I also demonstrate how these examples may be utilized in the statistics classroom as they relate to concepts covered in most basic statistics courses.

Complexity and then some: Theories of action and theories of learning in data-informed decision making

This article presents a synthesis of the complexity of using data in education and highlights some of the promise and challenges of adequately understanding data use across the continuum of accountability to instructional influence in the classroom. Several common themes around the complexity of data use were identified: (1) The nature of the data used, (2) the importance and difficulty of educator data capacity building and sense-making, (3) the importance of characteristics of collaboration, (4) the influence of contextual factors of schools, districts and international settings, (5) the potential negative influence of data use in equity considerations, and (6) the difficulty of determining impact of data use and discerning explanations of why data use initiative work some of the times were examined across the articles. This synthesis concludes with a call for an approach to research in data use in education that concurrently engages multiple aspects of the educational system with a focus on multiple levels of theories of learning that address students, teachers, and organizations.     

Did the preservice teacher-generated studies constitute actual instances of teacher-researcher studies, and were they consistent with notions of Dewey?

It is suggested that articles in an American Annals of the Deaf special issue on teacher action research constitute a 2-tiered metastudy: The first article serves as a literature review of the teacher-as-researcher notion; 5 subsequent articles form the data set for a higher-order teacher-as-researcher inquiry. It is maintained that the preservice teachers' work met the definition of teacher-as-researcher in that they systematically investigated their own teaching/learning practices through a reflective lens, with the twin purposes of modifying their own practices and contributing to the theoretical in situ knowledge base of learning and teaching in general. It is also argued that this body of work is consistent with the stance on inquiry advocated by Columbia University's Teachers College and its Program in the Education of the Deaf and Hard of Hearing, and that teacher research reflected Dewey's notions of pragmatism, functionalism, constructivism, communication, and social advocacy.     

What does it mean for teachers to be data literate: Laying out the skills,knowledge, and dispositions

This article reports on the evolution of a conceptual framework for a construct called data literacy for teachers. Data use has become an emphasis in education but few educators have received sufficient training or preparation pertaining to data literacy skills. This article lays out the framework, identifying the specific knowledge, skills, and dispositions teachers need to use data effectively and responsibly. It concludes with a call to schools of education and teacher preparation programs to begin to integrate data literacy into curricula and practical experiences.

Instruction in early childhood special education: "seeing through a glass darkly ... knowing in part".

This article discusses what is not known about instruction of preschoolers with disabilities. Knowledge gaps exist in four areas: the content of the curriculum, the procedures used to individualize instruction, the instructional procedures designed to ensure acquisition, and the strategies used to ensure skill use or generalization. Barriers to generating such knowledge include the fragmentation that results from specialization, the inadequacy of the data base, and the lack of training in instruction and research design and analysis. Solutions include training programs for early childhood special educators in the analysis, application, and design of research in instruction and curriculum, as well as the publication of multiple replications and refinements of instructional strategies.
