Primary school teachers' science competence remains a highly relevant theoretical and practical problem. Although the general curricula and educational standards of Lithuanian general education school set quite high requirements for the process of primary school science education, the science competence of teachers raises reasonable concerns. It…

The rise in online professional development (PD) opportunities for teachers, accelerated by the COVID-19 pandemic, necessitates an examination of the effectiveness of these online PD programs and the design elements that best enhance teachers' knowledge. This review synthesizes findings from nine studies that systematically investigate…

Emotions come into play as teachers make decisions, act, and reflect on the different purposes, methods, and meanings of math teaching. In order to learn more about the emotions of mathematics teachers, this paper shows the emotions experienced by 81 Mexican teachers who teach mathematics in middle school and high school. Emotions are…

How a sample of university educators described STEM, expected outcomes of STEM, expertise of STEM educators, and STEM learning environments were investigated through drawing- and text- based responses. Data were examined by applying the "Legitimation Code Theory (LCT) Specialisation" plane (Maton, 2014). Participants generally held…

Mathematics curricula are often the primary resource used in the teaching and learning of mathematics--in particular, they represent mathematical knowledge for teachers and students. Yet, there seems to be a discrepancy between the curricular materials written for teachers and students (e.g., more variety in the semiotic choices in text provided…

In mathematics education, subject matter knowledge matters! This paper reports findings from a study of relationships between teachers' understandings of content, the tasks they design and their interpretations of student thinking. A combined methods approach was used to gather multiple data sets from 64 upper primary teachers. The study found…

Functions form a central part of the U.S. mathematics curriculum especially at the high school level. There is a considerable body of research showing that students at all levels, including preservice secondary mathematics teachers, have difficulties with the definition of function as a correspondence between two sets with a univalence condition.…

In this paper, we examine junior secondary mathematics teachers' understanding of mathematical structure, and how they promote structural thinking in their teaching. Five teachers were surveyed, and three were interviewed and the observed teaching a junior secondary mathematics class. Results showed that teachers have conflicting understandings of…

Connected Learning for STEM (CL4STEM) is an innovative project aimed at teacher capacity building in science, technology, engineering, and mathematics involving communities of practice as its component to developing teachers' ability to adopt an innovative approach to science instruction and to implement a novel curriculum. Hence, this study…

Increasingly, mathematics is being positioned as a tool to support students' understandings of social (in)justice and their own unique social positioning in the world. To this end, this study analyzes the impact of curricular reform efforts in an elementary mathematics content course. The course focused on fractions and statistics, and the course…

In this paper, we report on changes to teachers' knowledge and practices as a result of their participation in a professional learning initiative focused on cognitively challenging tasks and the pedagogies for enhancing student reasoning as such tasks unfold. Data from 239 primary teachers who responded to an online pre- and post-professional…

Rowland's Knowledge Quartet (KQ) model can provide illuminating insights into teacher practice in mathematics classrooms. This paper explores a framework developed for pedagogical technology knowledge (TPACK) to consider teacher practice in integrated technology classrooms alongside the KQ model. Observations of a Year 11 class in an Australian…

Pre-service teachers (PSTs), like practising teachers, enact their mathematical content knowledge (MCK) in pursuit of instructional goals during lessons. In this study, I explored the relationship between six secondary mathematics pre-service teachers' goals and the MCK that they chose to enact in 10 lower secondary algebra lessons. The findings…

Modeling student knowledge while students are acquiring new concepts is a crucial stepping stone towards providing personalized automated feedback at scale. We believe that rich information about a student's learning is captured within her responses to open-ended problems with unbounded solution spaces, such as programming exercises. In addition,…

This paper reports a pilot study to determine the potential impact of an integrated STEM curriculum on Pre-K teachers' engineering content knowledge, self-efficacy and teaching practice. Using a randomized control trial design, researchers examined the impact of the curriculum in 17 Pre-K classrooms (8 intervention classrooms, 9 control…
