30. Which item type could the teacher include to assess developing level 2.0 proficiency?
Answer: D
Multiple-choice items that ask students to define key terms related to the Pythagorean theorem
To assess developing level 2.0 proficiency, which involves providing definitions for relevant terms and functions related to the use of the Pythagorean theorem, multiple-choice items that focus on defining key terms are appropriate.
A) Multiple-choice items that ask students to determine the perimeter of triangles
This option is not suitable for assessing level 2.0 proficiency as it does not focus on definitions or relevant terms related to the Pythagorean theorem. Instead, it emphasizes perimeter calculations which are not aligned with the specific skill of defining concepts.
B) Constructed-response items that ask students to solve word problems and show how they arrived at the solutions
While this option allows for deeper engagement with problem-solving, it targets higher levels of proficiency. Level 2.0 requires students to focus on definitions, not necessarily to demonstrate problem-solving techniques or solution processes.
C) A performance task that asks students to use the Pythagorean theorem to experiment with different shapes
Although this option promotes practical application of the theorem, it is more aligned with higher proficiency levels that include applying knowledge rather than simply defining terms. Level 2.0 specifically focuses on definitions rather than experimental applications.
D) Multiple-choice items that ask students to define key terms related to the Pythagorean theorem
This option is correct as it directly aligns with the level 2.0 proficiency goal of providing definitions for relevant terms. It assesses students' understanding of the foundational language and concepts necessary for further application of the Pythagorean theorem.
Conclusion
Option D is the most appropriate choice for assessing developing level 2.0 proficiency because it directly targets the students' ability to define key terms associated with the Pythagorean theorem. The other options, while educationally valuable, focus on higher levels of application and problem-solving, which are not relevant for the specific proficiency level being assessed.
