Concetti Chiave
ACE focuses on Analyzing, Evaluating, and Creating levels in Bloom's Taxonomy for assessing computational skills.
Sintesi
The content discusses the development of ACE, a test focusing on higher cognitive levels in Bloom's Taxonomy for evaluating computational thinking skills. It includes an abstract, introduction, related work, study details, results, limitations, conclusion, and future work. The test comprises 21 multi-choice items based on block-based visual programming tasks from Hour of Code: Maze Challenge by Code.org. Results confirm the reliability and validity of ACE through psychometric analysis with 371 students in grades 3-7.
Abstract:
- CT and problem-solving skills integrated into K-8 curricula worldwide.
- Need for reliable assessments to measure proficiency.
- Development of ACE test focusing on Analyzing, Evaluating, Creating levels.
Introduction:
- Importance of CT as a critical skill in today's digital world.
- Integration of CT into K-8 curricula globally.
Related Work:
- Overview of various CT assessments based on format and cognitive levels.
Study Details:
- Two-phase data collection process with 371 students from grades 3-7.
Results:
- Good fit statistics for internal structure assessment using CFA.
- Reliability confirmed through Cronbach alpha value and IRT analysis.
Limitations:
- Evaluation limited to HoCMaze scores; potential improvements suggested for item presentation.
Conclusion & Future Work:
- ACE validated for assessing CT skills; suggestions for future enhancements discussed.
Statistiche
Recent works have proposed tests for assessing these skills across various CT concepts and practices - Recent works have proposed several assessments that measure students’ CT during their K-8 academic journey. - These assessment tools are essential for tracking the progress of students - Prior work has proposed several CT assessments based on their format including portfolios - Several works have also discussed the multi-faceted nature of CT and its broader role in the acquisition of creative problem-solving skills - The test contains items grounded in the domain of block-based visual programming
