3. Student Performance Assessment (Justin) 3. 学生表现评估 (Justin)

Participation and Activeness 参与度和积极性

Student was responsive, particularly when prompted with related concepts (e.g., identifying sperm/egg). Required significant prompting for definitions (e.g., Eukaryotic, Mutation). 学生反应积极，尤其是在被提示相关概念时（例如，识别精子/卵子）。对定义（例如，真核生物、突变）需要大量提示才能回忆起来。

Language Comprehension and Mastery 语言理解和掌握

Language Output Ability 语言输出能力

Oral: 口语：

Communication was clear but hesitant on specific scientific terminology. Followed the teacher's line of questioning well. 交流清晰，但在特定的科学术语上犹豫不决。很好地跟上了老师的提问思路。

Written: 书面：

N/A (Session was primarily oral explanation and discussion).

不适用（本次课程主要以口头解释和讨论为主）。

Student's Strengths 学生的优势

Able to recall the chromosome number (46) for normal human cells. 能够回忆起正常人体细胞的染色体数量（46）。
