Science and STEM Education Flashcards

Which type of assessment is most aligned with science inquiry — asking students to design an experiment to test a question?

Answer: Performance-based assessment

Performance-based assessments require students to apply science practices (like experimental design) in authentic ways, directly measuring inquiry and reasoning skills.

A student's investigation shows unexpected results that contradict their hypothesis. What should the teacher encourage the student to do?

Answer: Analyze potential sources of error and consider what the data actually shows

Scientists examine unexpected results as learning opportunities by analyzing sources of error and considering alternative explanations — this models authentic scientific reasoning.

Which NGSS disciplinary core idea addresses the concept that matter is not created or destroyed during physical or chemical changes?

Answer: PS1: Matter and Its Interactions

PS1 (Matter and Its Interactions) includes the conservation of matter — the idea that matter is neither created nor destroyed during physical or chemical changes.

A kindergarten teacher observes a student sorting animals into groups: 'animals with legs' and 'animals without legs.' Which science practice is this student engaged in?

Answer: Analyzing and interpreting data

Classifying animals by observable characteristics is a form of analyzing data — students are organizing observations to identify patterns and similarities.

Which approach to integrating STEM in elementary school is considered most effective for developing problem-solving skills?

Answer: Using project-based learning with authentic, real-world problems

Project-based learning with real-world problems engages students in authentic STEM reasoning and collaboration, developing transferable problem-solving skills.

A teacher wants to address alternative conceptions students have about science. Which strategy is most effective?

Answer: Creating cognitive conflict by designing experiences that challenge the misconception

Creating cognitive conflict through carefully designed experiences challenges students' existing misconceptions and provides the impetus needed to restructure their understanding.
