According to an ecological affordances perspective, any static curriculum has a set of affordances, and differences in teachers, students, and the teaching environment change how those affordances are viewed and used. Therefore, teaching is a relationship between the curriculum, the teacher, and the students. As such, it is not only possible but expected that a teacher will diverge from the details of a lesson plan to better accommodate the needs of themselves as a teacher and their students as learners. In this study, we report on a mixed-methods investigation that explores the different ways upper-elementary and middle-school (7- 13 y.o. students) teachers implement the Scratch-based TIPP&SEE learning strategy and the reasoning for their approaches. As expected, we find that teachers across grade levels often deviate from lesson plan details to cater to their own classrooms. For example, teachers serving younger grades were far more likely to keep scaffolds that lesson plans suggest removing. The varied degree of deviation suggests that the repeated use of a learning strategy, alongside lesson plans that present a variety of scaffolded implementations, is beneficial in enabling teachers to adapt lesson content to serve the needs of their specific classroom. 

Background and Context: The study was conducted in a special education classroom in an elementary school with multilingual Latine students, utilizing a computer science curriculum focused on community-based environmental literacy. Objective: This study explores the experiences of diverse elementary students with disabilities in learning computer programming and identifies instructional strategies that enhance their learning within a culturally sustaining curriculum. Method: An exploratory case study approach was used to examine students’ learning experiences and teachers’ instructional strategies during curriculum implementation. Findings: Students who typically did not engage with peers collaborated effectively, and those with behavioral and performance difficulties exhibited heightened engagement. Instructional strategies included multisensory engagement and connecting environmental and computational concepts to real-life situations. Implications: The result underscore how a culturally sustaining computer science curriculum can empower diverse students, foster inclusivity, and leverage their strengths through effective teaching practices. 

As reliance on technology increases in practically every aspect of life, all students deserve the opportunity to learn to think computationally from early in their educational experience. To support the kinds of computer science curriculum and instruction that makes this possible, there is an urgent need to develop and validate computational thinking (CT) assessments for elementary-aged students. We developed the Assessment of Computing for Elementary Students (ACES) to measure the CT concepts of loops and sequences for students in grades 3-5. The ACES includes block-based coding questions as well as non-programming, Bebras-style questions. We conducted cognitive interviews to understand student perspectives while taking the ACES. We piloted the assessment with 57 4th grade students who had completed a CT curriculum. Preliminary analyses indicate acceptable reliability and appropriate difficulty and discrimination among assessment items. The significance of this paper is to present a new CT measure for upper elementary students and to share its intentional development process.
