  • Exploratory Behavior Scale (EBS)

    Expert Notes
    Strengths:

    Captures the quality of young children’s hands-on exploration (e.g., passive contact vs. active manipulation vs. exploratory variation), providing more nuanced insight into learning-related behavior than simple time-based measures.

    Cautions:

    Relies on observational coding of children’s behavior, which requires trained observers and may introduce subjectivity or variability in scoring across different raters or settings.

    The Exploratory Behavior Scale (EBS) is an observational assessment tool designed to measure young children’s hands-on exploratory behavior in interactive learning environments. The instrument is designed to capture the quality of children’s interaction with materials and to enable comparisons…

  • Preschool Assessment of Science (PAS)

    Expert Notes
    Strengths:

    Performance-based and structured as a sequence of prediction–observation–prediction tasks, allowing it to capture children’s scientific reasoning processes and how they revise their thinking based on evidence.

    Cautions:

    Uses a relatively small number of items per task, which may limit reliability and the ability to capture the full range of children’s scientific understanding and variability in performance.

    The Preschool Assessment of Science (PAS) is a performance-based assessment designed to measure preschool children’s science knowledge and inquiry skills through hands-on tasks. The instrument focuses on children’s ability to engage in a cycle of scientific reasoning, including making predictions,…

  • Custom-built electronic toy to test causal structure knowledge

    Expert Notes
    Strengths:

    Uses a hands-on, manipulable physical system to elicit children’s reasoning, allowing researchers to directly observe how preschoolers infer and test causal relationships rather than relying solely on verbal explanations or abstract questions.

    Cautions:

    The custom-built device may be a barrier for some educators looking to use this assessment.

    This assessment is a task-based instrument designed to measure preschool children’s understanding of causal relationships through structured interaction with a physical system. The instrument uses a custom-built device consisting of two gears and a switch, where different underlying causal…

  • Life Science Assessment

    Expert Notes
    Strengths:

    The LSA uses photographs paired with open-ended, oral questions, which is developmentally appropriate for preschool children and allows them to express their understanding without relying on reading or writing skills.

    Cautions:

    Because the LSA relies on open-ended, verbally administered responses, scoring can be subjective and may vary between raters.

    The Life Science Assessment provides insight into children’s emerging inquiry skills and conceptual development by focusing on how they reason about real-world phenomena, rather than simply what they know. The assessment consists of structured, hands-on tasks centered on familiar physical science…
  • The Computational Thinking Test (CT-test)

    Expert Notes
    Strengths:

    Systematically assesses a wide range of core computational thinking concepts (e.g., sequences, loops, conditionals, and functions) across progressively increasing difficulty levels, providing a comprehensive measure of students’ CT development.

    Cautions:

    Uses multiple-choice, decontextualized tasks (e.g., maze or canvas problems), which may not fully capture how students apply computational thinking in authentic, open-ended coding or robotics activities.

    The Computational Thinking Test (CT-test) is a multiple-choice assessment designed to measure students’ computational thinking skills across a range of core programming concepts in elementary and secondary educational contexts.The test evaluates several dimensions of computational thinking,…
