Learning fractions is essential for academic and daily life success. A critical first step in acquiring fractions is learning to transcode them (e.g., writing ½ when hearing "one half"). However, little is known about how students master fraction transcoding. We addressed this gap by assessing fraction writing in two groups of Brazilian…

Background and context: Despite the growing importance of computer science (CS) education, high-quality CS curricula for students in kindergarten to lower elementary grades are lacking. It is also unclear how students from underrepresented groups such as female students, students from low socioeconomic status, and students with disability respond…

The present study has been developed in order to inquire the cognitive awareness of the 2nd grade-level students of the Science Teaching program on "sensors", which has an important place in the development of the robotic and automation systems. In the study, the method of case study, which is one of the qualitative research motifs, was…

Project-based assessment has been used to evaluate coding projects created by students for a long time. Nevertheless, there is a lack of rigorously tested project-based coding rubrics that are developmentally appropriate for early childhood. This study presented the development and testing of a coding rubric to evaluate children's creations with…

The aim of this study was to explore how the Coding as Another Language (CAL) curriculum, developed by Boston College's DevTech Research Group and utilizing the ScratchJr app, impacted students' computational thinking, coding skills, and reading comprehension. To accomplish this, the research team randomly assigned thirteen schools in a…

Making accurate judgements and interpretations about student growth and progress in mathematics can be problematic when using open-ended assessments. This study reports on the development of a class-based assessment instrument and marking key designed to assess Year 2 students' mathematics competence to reflect their learning of mathematics…

We describe a LEGO-compatible Internet of Things Technology (IoT) designed to enable elementary school students to learn about IoT by building their own smart, connected products. The Internet of Things is any network of physical devices that can share information over the internet. Using small, Wi-Fi enabled microprocessors, Grove sensors,…

Developing computational thinking (CT) skills at an early age can help develop literacy, science, and mathematics skills; however, CT instruction in grades K-2 remains limited. This study examined the perceptions of 45 K-2 teachers from 30 school districts before and after a CT professional development (PD) experience. The PD included two online…

In today's multimodal landscape, coding has a space in the elementary literacy curriculum. Coding and literacy have many parallels, which are described in further detail. The author also explains why coding should be integrated into the primary grades and the steps that teachers can take to implement coding in the literacy curriculum. The free app…

Learning coding during early childhood is an effective way for children to practice computational thinking. Aspects of children's motivation can increase the likelihood that children approach computational thinking activities with enthusiasm and deep engagement. Gender inequities may interfere with children's readiness to take advantage of…

The aim of this study was to explore how the Coding as Another Language using ScratchJr (CAL-ScratchJr) curriculum, developed by Boston College's DevTech Research Group utilizing the ScratchJr app, impacted second grade students' computational thinking, coding skills, and reading comprehension. To accomplish this, the research team randomly…

Aim/Purpose: This paper presents findings on a curricular intervention aimed at integrating computer programming with reading and writing in early elementary school. The purpose of this research was to explore the relation between students' varying literacy levels and their level of success in mastering an introductory programming language.…

Aural preparation is operationally defined as hearing, performing, decoding, and creating rhythms or pitches aurally prior to the introduction of music notation. The purpose of this study was to explore the effect of aural preparation on second grade students' music literacy rhythm skills (i.e. reading, performing, and dictation). The research…

There is a need for developmentally appropriate Computational Thinking (CT) assessments that can be implemented in early childhood classrooms. We developed a new instrument called "TechCheck" for assessing CT skills in young children that does not require prior knowledge of computer programming. "TechCheck" is based on…

Treatment fidelity data (descriptive and statistical) are critical to interpreting and generalizing outcomes of intervention research. Despite recommendations for treatment fidelity reporting from funding agencies and researchers, past syntheses have found treatment fidelity is frequently unreported (e.g., Swanson, "The Journal of Special…
