To demonstrate the capability of computer vision analysis to detect atypical orienting and attention behaviors in toddlers with autism spectrum disorder. One hundred and four toddlers of 16-31 months old (mean = 22) participated in this study. Twenty-two of the toddlers had autism spectrum disorder and 82 had typical development or developmental…

Research on teacher noticing in the field of mathematics education research has increased in the last decade; however, only a few studies have investigated the social and cultural impact on teachers' noticing. This paper describes results of an international comparative study on (in-service) mathematics teachers' professional noticing in China and…

The newest edition of the "Diagnostic and Statistical Manual of Mental Disorders" (5th ed., DSM-5) introduced substantial changes to the diagnostic criteria for autism spectrum disorder, including new severity level ratings for social communication and restricted and repetitive behavior domains. The purpose of this study was to evaluate…

Classroom observation protocols can provide an exceedingly rich form of data. However, this is a double-edged sword, as researchers often struggle to take full advantage of the detailed data outputs. In this essay, we introduce a new approach to the analysis of classroom observation data, termed "classroom as genome" (CAG). We illustrate…

Lesson observation has been used with pre- and in-service teachers to improve classroom practices. In addition, reflection and criticality can be developed when teachers use evidence from their lessons and engage in collaborative discussions. Therefore, it is essential for pre-service teachers to collect data from their practices and reflect upon…

Although mathematics standards have changed dramatically in recent years, teaching mathematics is as complex as it has always been. Some would argue that mathematics teaching has become even more complex, with the implementation of the Common Core State Standards for Mathematics (CCSS-M) (NGA Center & CCSSO, 2010), as teachers are being asked…

This paper addresses the gaps between language documentation and language revitalization. It is intended for several audiences, including field linguists interested in supporting endangered language sustainability efforts and participants of all kinds in language revitalization courses, programs, and infrastructure. The authors contend that…

The accountability pressures of the recent decade require that instructional leaders work with teachers to ensure student academic success. The "walkthrough" or "walkthrough observation" is an instructional leadership practice that has been regarded as a promising avenue to collaboratively work with teachers. This exploratory…

The use of data-based decision making (DBDM) in schools to drive educational improvement and success has been strongly promoted by educational experts and policymakers, yet very little is documented about the actual DBDM practices used in schools. This study examines DBDM practices in 25 middle schools through 80 standardized observations of data…

In this qualitative case study, we provide a series of vignettes illustrating a Grade 1 teacher's experiences integrating iPad technology into her instruction over a school year. We use the digital didactic model to deconstruct these vignettes and draw upon the teacher's reflections to gain further insights about her instructional experiences…

The purpose of this qualitative case study utilizing ethnographic methods was to understand how family members' participation in Digital Home, a community-based technology program in an urban mid-sized Midwestern city, built on and fostered Latino immigrant families' community cultural wealth (Yosso, 2005) in order to increase their abilities to…

Many ground-dwelling amphibians, reptiles, small mammals, insects, and other arthropods seek cover during their resting hours. Their natural hideaways include underground burrows, rotting logs, and leaf litter, which are widely distributed and difficult to discover and observe. To make observation easier, scientists, educators, and students can…

The focus on professional noticing in mathematics education has recently gained increased interest as researchers work to understand how and what is noticed and how this translates into practice. Much of this work has focused on the professional noticing practices of inservice teachers and preservice teachers, with less attention focused on those…

This article begins with a series of meta-level comments on the enterprise of observing and theorizing classroom teaching, using as a springboard a frequently discussed model from the literature. It then provides a series of commentaries on the empirical articles in this issue (volume 48, issue 1) of "ZDM," with a main focus on…

The issue of whether trainee teachers in the post-16 sector should have their classroom practice graded has been debated for a number of years. The case for training courses retaining an emphasis on written and verbal "developmental" feedback at the expense of "judgements" appears to be lost. This article is set within the…
