“Homework Feedback Is…”: Elementary and Middle School Teachers’ Conceptions of Homework Feedback

This study explored mathematics teachers' conceptions of the homework feedback focusing on four key aspects: definition, purpose, types, and perceived impact. Forty-seven teachers from elementary and middle schools participated in six focus groups. Data were analyzed using content analysis. To enhance the trustworthiness of findings, classroom observations were used for triangulation of data. P...

The effects of teachers' homework follow-up practices on students' EFL performance: a randomized-group design

This study analyzed the effects of five types of homework follow-up practices (i.e., checking homework completion; answering questions about homework; checking homework orally; checking homework on the board; and collecting and grading homework) used in class by 26 teachers of English as a Foreign Language (EFL) using a randomized-group design. Once a week, for 6 weeks, the EFL teachers used a ...

Homework - 8

In this homework, we reconstruct the 3D structure of an image using the point correspondences obtained by edge detection and NCC measure. There are a series of steps involved to reconstruct the 3D structure which will be discussed in the next section. Algorithm: Although its possible to reconstruct the 3D structure using multiple images, for the sake of simplicity, I am using two images taken u...

Exercise [1.1.13] (a) Let G = ⋂ α Fα, with each Fα a σ-algebra. Since Fα a σ-algebra, we have that Ω ∈ Fα, and as this applies for all α, it follows that Ω ∈ G. Suppose now that A ∈ G. That is, A ∈ Fα for all α. Since each Fα is a σ-algebra, it follows that A ∈ Fα for all α, and hence A ∈ G. Similarly, let A = ⋃ iAi for some countable collection A1, A2, . . . of elements of G. By definition of ...
