1. Data collection and analysis for preschoolers: An engaging context for integrating mathematics and computational thinking with digital tools

   Lewis_Presser, A E; Young, J M; Rosenfeld, D; Clements, L J; Kook, J F; Sherwood, H; Cerrone, M (June 2023, Early childhood research quarterly)

   Collecting and organizing data to understand and answer real-world questions is an increasingly important skill in our current world. Fostering data collection and analysis (DCA) skills in young children leverages key mathematics skills as well as the data representation, visualization, and interpretation skills of computational thinking (CT), culminating in a problem-solving approach with data. As such, the intervention, comprising investigations and a digital app, supported preschool teachers and children to answer data-focused questions by engaging in each step of the DCA process in order to foster CT and math skills. Teachers appreciated that the app offers a new way for children to visualize data and noted that the app provided learning opportunities for children that would not otherwise be possible or easy to implement. Results also suggest that the app provides a systematic process for data collection, entry, and interpretation. Children in classrooms that completed the intervention had significantly higher scores at post-intervention compared to children in classrooms that did not complete the intervention, controlling for pre-intervention scores, B(SE) = 0.13(0.05), t (6) = 2.48, p = .048.

   Lewis Presser, A. E. (March 2022, International journal of integrating technology in education)

   To support preschool children’s learning about data in an applied way that allows children to leverage their existing mathematical knowledge (i.e. counting, sorting, classifying, comparing) and apply it to answering authentic, developmentally appropriate research questions with data. To accomplish this ultimate goal, a design-based research approach [1] was used to develop and test a classroom-based preschool intervention that includes hands-on, play-based investigations with a digital app that supports and scaffolds the investigation process for teachers and children. This formative study was part of a codesign process with teachers to elicit feedback on the extent to which the series of investigations focused on data collection and analysis (DCA) and the teacher-facing app were (a) developmentally appropriate, (b) aligned with current preschool curricula and routines, (c) feasible to implement, and (d) included design elements and technology affordances teachers felt were useful and anticipated to promote learning. Researchers conducted in-depth interviews (n=10) and an online survey (n=19) with preschool teachers. Findings suggest that teaching preschoolers how to collect and analyze data in a hands-on, play-based, and developmentally appropriate way is feasible and desirable for preschool teachers. Specifically, teachers reported that the initial conceptualization of the investigations were developmentally appropriate, aligned with existing curricular activities and goals, was adaptable for the age and developmental readiness of young children, and that the affordances of the technology are likely to allow preschool children to engage meaningfully in data collection, visualization, and analysis. Findings also suggest that this approach to supporting preschool teachers and children to learn about and conduct DCA merits further study to ensure productive curricular implementation that positively influences preschoolers’ learning. These findings were used to revise the investigations and app, which showed positive outcomes when used in classrooms [2], which add to the scant literature on DCA learning for pre-schoolers and provides insights into the best ways to integrate technology into the classroom.

3. Engaging preschoolers in data collection and analysis with manipulatives, body movement, and digital technology

   Lewis Presser, A. E. (February 2021, Early Childhood STEM Conference)

   null (Ed.)

   This workshop will focus on how to teach data collection and analysis to preschoolers. Our project aims to promote preschoolers’ engagement with, and learning of, mathematics and computational thinking (CT) with a set of classroom activities that engage preschoolers in a data collection and analysis (DCA) process. To do this, the project team is engaging in an iterative cycle of development and testing of hands-on, play-based, curricular investigations with feedback from teachers. A key component of the intervention is a teacher-facing digital app (for teachers to use with students on touch-screen tablets) to support the collaboration of preschool teachers and children in collecting data, creating simple graphs, and using the graphs to answer real-world questions. The curricular investigations offer an applied context for using mathematical knowledge (i.e., counting, sorting, classifying, comparing, contrasting) to engage with real-world investigations and lay the foundation for developing flexible problem-solving skills. Each investigation follows a series of instructional tasks that scaffold the problem-solving process and includes (a) nine hands-on and play-based problem-solving investigations where children answer real-world questions by collecting data, creating simple graphs, and interpreting the graphs and. (b) a teacher- facing digital app to support specific data collection and organization steps (i.e., collecting, recording, visualizing). This workshop will describe: (1) the rationale and prior research conducted in this domain, (2) describe an intervention in development focused on data collection and analysis content for preschoolers that develop mathematical (common core standards) and computational thinking skills (K-12 Computational Thinking Framework Standards), (3) demonstrates an app in development that guides teacher and preschoolers through the investigation process and generates graphs to answer questions (NGSS practice standards), (4) report on feedback from a pilot study conducted virtually in preschool classrooms; and (5) describe developmentally appropriate practices for engaging young children in investigations, data collection, and data analysis.

4. Enhancing Preschool Spatial Skills: A Comprehensive Intervention Using Digital Games and Hands-On Activities

   https://doi.org/10.3390/educsci15060727  

   Lewis_Presser, Ashley E; Braham, Emily; Vidiksis, Regan (June 2025, Education Sciences)

   This paper describes the development and testing of a classroom and complementary home-based intervention to build preschoolers’ spatial orientation skills, focusing on exploring implementation feasibility and initial child learning outcomes. Spatial orientation, one type of spatial thinking, involves understanding the relationship between spatial positions, using maps and models to represent and navigate through space, and using spatial vocabulary. Evidence continues to accumulate that gaining spatial skills helps overall mathematics achievement and that learning resources are needed in this field. This mixed-methods study is the third in a series of investigations that leverage a design-based implementation research approach to develop preschool resources to support spatial orientation with both hands-on and technology-based experiences. Through a quasi-experimental comparison study, treatment teachers implemented eight weeks of hands-on activities, read-aloud stories, and digital activities (including an augmented reality app) and a sample of families also engaged in complementary home-based activities. The findings suggest that the resources help teachers feasibly implement spatial lessons, and preschoolers improve their learning of spatial concepts with the use of the classroom and home-based intervention.

5. Developing and Formatively Testing a Preschool Classroom Intervention using a Design-Based Implementation Approach

   Lewis_Presser, A E (June 2025, International journal of education)

   This paper presents the development and formative testing of a preschool spatial orientation intervention using a design-based implementation research (DBIR) approach. Over the course of eight weeks in both classroom and home settings, spatial language, navigation, and modelling skills are fostered through curriculum that incorporates books, hands-on activities, movement, and digital tools, including an augmented reality (AR) app. Co-design with teachers, user studies, and pilot testing informed iterative revisions to ensure usability, instructional support, and engagement for diverse learners. Findings indicate that the activities fill a curricular gap, promote spatial vocabulary and reasoning, and are generally well received by teachers, parents, and children. While the AR app shows promise for enhancing motivation and collaboration, challenges related to usability and scaffolding remain. This work contributes to early childhood STEM education by providing accessible, developmentally appropriate resources that support spatial thinking, especially for underserved communities, and offers insights into integrating technology effectively in preschool learning environments.
