The content analysis included video lectures posted in 208 MOOCs on the Polish educational platform NAVOICA. The aim was to determine their subject matter and the methods of preparing video lectures. It turned out that video lectures were included in 57% of MOOCs, most often related to "Medical and health sciences" and…

To address the computational constraints of parameter estimation in the polytomous Cognitive Diagnosis Model (pCDM) in large-scale high data volume situations, this study proposes two two-stage polytomous attribute estimation methods: P_max and P_linear. The effects of the two-stage methods were studied via a Monte Carlo simulation study, and the…

In this study, we sought to understand what might be learned about preservice teachers' mathematics learner and mathematics educator identities in the context of a problem-solving focused mathematics content course. Twenty-two preservice teachers participated in this study as part of their undergraduate teacher preparation program. We implemented…

To base teaching on student thinking requires analyzing and interpreting students' thinking, key components of the construct of professional noticing (e.g., Jacobs et al., 2010). Although substantial research has been conducted using this construct, less attention has been paid to teachers' evaluations of student work based on these analyses and…

Using narrative inquiry, I share the beginning stories of the instructional visions of secondary mathematics teachers throughout their undergraduate studies of pedagogy and content-specific methods and evidenced in undergraduate coursework and student teaching experience. Guided by Munter's (2014) Visions of High-Quality Mathematics Instruction…

Big Ideas in school mathematics can be seen as overarching concepts that occur in various mathematical topics in a syllabus. For teachers, this knowledge can be used to help students develop a better understanding of mathematics by making visible the central ideas, and connection across topics and across levels. For students, this knowledge can…

This study aims to explore the challenges and opportunities of using digital technology in English teaching in higher education. Transforming the teaching and learning process from face-to-face to online learning by utilising digital technology devices and internet connectivity becomes challenging for lecturers and students. However, there are…

Literature portrays advanced mathematics lecturing as a uniform teaching style, often criticized for offering minimal opportunities for student participation. In this paper we present results from a comparative case study of two instructors' facilitation of student participation in Real Analysis lectures. Analyzing fieldnotes from several observed…

The synthetic control method (SCM) is a popular approach for estimating the impact of a treatment on a single unit with panel data. Two challenges arise with higher frequency data (e.g., monthly versus yearly): (1) achieving excellent pre-treatment fit is typically more challenging; and (2) overfitting to noise is more likely. Aggregating data…

Evaluators widely agree that the involvement of key actors is a central aspect of quality practice. However, a scoping review of to what extent and how youth are included has not been explored. This is an important omission because many evaluations are done on programs that directly serve youth. We examined 159 evaluation reports in a publicly…

Developing models and using mathematics are two key practices in internationally recognized science education standards such as the Next Generation Science Standards (NGSS, 2013). In this paper, we used a virtual performance-based formative assessment to capture students' competencies at both "developing" and "evaluating"…

Technology in education is purposely designed to help both educators and students in knowledge transfer and knowledge gain simultaneously. In many aspects, technology in education is supposed to prove that education can be delivered effectively and efficiently. However, there are cases in which technology in education can be frustrating and…

Scholarly opinion on the usefulness of podcasting in higher education has been mixed. Considering the variety of methods of teaching and learning, the existing scholarship on the subject in any particular one has been inadequate to measure podcasting's promise. This case study of a podcast-infused, fully-online Western Civilization survey course…

In this paper, we present the findings from the first year of our study into the use of talk with young children (ages 6 and 7) in their mathematics lessons following four teachers' implementation of dialogic strategies. Based on Alexander's (2017) dialogic principles and notions of productive talk, we delivered a professional implementation…

Despite substantial research exploring multiplicative thinking and students' difficulty in the domain, the topic of multi-digit multiplication is under-researched. In this paper, I share a learning trajectory for multi-digit multiplication that combined social and cognitive perspectives of learning. Using Design Research methods and involving 45…
