(A) The wavefunction Ψ_B(x) will yield the largest value for ⟨x⟩. (B) The wavefunction Ψ_C(x) will yield the largest value for ⟨x²⟩. (C) The wavefunction Ψ_C(x) will correspond to the highest kinetic energy. (D) All wavefunctions Ψ_A(x), Ψ_B(x) and Ψ_C(x) will yield the largest value for ⟨x⟩. (E) All wavefunctions Ψ_A(x), Ψ_B(x) and Ψ_C(x) will yield the largest value for ⟨x²⟩.

19. Consider the angular momentum of an electron in the 2Pz orbital of hydrogen atom. Which of the following are wrong? (A) The electron has a nonvanishing projection of angular momentum in the z direction. (B) If the projection of electron angular momentum in the x direction is measured, it always yields zero. (C) If the total electron angular momentum is measured, it yields a distribution with a finite width. (D) If the projection of electron angular momentum in the z direction is measured, it always yields an identical value. (E) If a magnetic field in the z direction is applied, it will shift the electron energy.

18. Consider a p-n diode. Which of the following are correct? (A) Near the p-n junction, electrons and holes diffuse and recombine, resulting in a depletion region. (B) When forward biased, there will be electrons flowing from n side to p side. (C) When forward biased, there will be holes flowing from p side to n side. (D) When unbiased, the Fermi energy is aligned throughout the diode. (E) When unbiased, the conduction band edge is aligned throughout the diode.

43 下列有關使用學習指標之敘述,何者不正確? (A)現今的課程大綱提供的學習指標就是幼兒的學習方向,因此不須再刻意書寫教學目標或活動目標 (B)學習指標「認‐中‐2‐2‐1 依據特徵為自然現象分類並命名」活動設計的重點是要讓幼兒認識自然現象特徵 (C)學習指標提供的方向是最基礎的,如果幼兒園因自身的特色而有其它的學習方向,只要不違背課程大綱的精 神,可在原有學習指標的基礎上增加提供給幼兒的經驗 (D)各領域的學習指標並非評量指標,是教保服務人員規劃課程的藍圖,所以沒有幼兒是否達到學習指標的問題

69.林教授開發了測量學生學習投入的量表,將此量表的分數與同時間教師對學生學習投 入的評分比較。請問這是何種效度? (A) 預測效度 (B) 外部效度 (C) 建構效度 (D) 同時效度
