For organisations to thrive, their employees need to be trained and developed. The training must be specific and targeted to the benefit of both the individual employee and the organisation they serve. The training and development can be for the development of the individual which will directly benefit the organisation. In reverse, whole…

Building Thinking Classrooms (Liljedahl, 2021) provides teachers with a new method of designing and sequencing tasks called "thin slicing," which emerged from variation theory. The results of the present study indicate that an analysis of the dimensions and ranges of variation within such a task offers insights into learning…

In this paper we examine how teachers who are pursuing their Elementary Mathematics Specialist certification--Elementary Mathematics Specialists in Training (EMSTs)--are positioned in their advice and information networks for mathematics. We analyzed the instructional networks of six elementary schools in one Midwestern school district. Our…

Professional learning for school mathematics leaders is a key aspect of the Victorian Government's strategy for improving mathematics for Victorian students. This is because middle leaders in schools play a vital role in designing and leading school improvement. As part of the Numeracy Suite, four online courses were designed in 2020 to support…

Primary mathematics leaders work together both with and between school leadership and teachers as middle leaders, balancing expectations and responsibilities of themselves, school leadership, and teachers. This paper presents a case study of mathematics leaders in a school with a diverse community and frequently changing staff. It explores the…

Action research is a means for teachers and researchers to develop evidence-based practices. This paper reports the process and outcomes of "teaching sprints," an approach to action research, conducted by secondary school mathematics leaders as part of a professional learning program. Mathematics leaders consistently reported the value…

Primary mathematics leadership has become a focus for improving the teaching of mathematics within Australian primary schools. Much of the training and support for those in the role have concentrated on content knowledge, rather than leadership training. There are currently no guidelines or standards in place to support the complex and…

Leading primary school mathematics involves stimulating teacher learning for the purpose of improving students' mathematical outcomes. Currently there are staff shortages and school mathematics leadership may have changed. The results of a semi-structured interview with an experienced School Mathematics Leader who reflected on her work are…

School districts across the United States are turning to mathematics teacher leaders (MTLs) to support the teaching and learning of mathematics. And yet, what does research seem to say about MTLs? In this paper, we report findings from an exploration of PME-NA proceedings between 1984 and 2019 to examine the role of MTLs. In particular, we examine…

Leadership in educational settings, especially in schools, has a long history. Instructional leadership is a leadership style that is seen to increase school effectiveness. This study aims to map bibliographic data on instructional leadership over the past eight decades (1941-2022). The quantitative research approach to analyzing bibliographic…

This paper highlights findings from two aspects of a case study on the partnership between one mid-size California public school district and a private university sponsored literacy project to cultivate teacher efficacy and reignite early student literacy during and after COVID-19 contexts. Grounded in teacher efficacy in literacy instruction and…

While such connection between an instructional leader and a vigorous teacher-leader team seems natural in the school with instructional effectiveness, the research evidence is surprisingly limited. To fill the gap, these factors are linked such that principals' effort on instruction will lead them to change the school's leadership structure by…

The aim of this article is to report the validity and reliability of Teacher Leadership Inventory (TLI). The sample of the study consists of 244 trained teachers who are chosen using random sampling technique from 19 secondary schools in Perak. The content validity, criterion validity and construct validity analyses have been carried out by using…

This 5-year mathematics professional development project involves 27 elementary teachers prepared and supported as Elementary Mathematics Specialists (EMSs) in high-need urban schools. They complete a university's K-5 Mathematics and Teacher Supporting & Coaching Endorsement programs and participate in Professional Learning Communities and…

Effective middle leading of mathematics is a complex task as it requires a focus on improving learning outcomes for students. This study gathered information about the activities of middle leaders of mathematics using a survey of primary and secondary mathematics leaders. Both primary and secondary mathematics leaders more often focussed on…
