Effects of Annotations and Homework on Learning Achievement: An Empirical Study of Scratch Programming Pedagogy

In Taiwan elementary schools, Scratch programming has been taught for more than four years. Previous studies have shown that personal annotations is a useful learning method that improve learning performance. An annotation-based Scratch programming (ASP) system provides for the creation, share, and review of annotations and homework solutions in the interface of Scratch programming. In addition...

Phased-Array Homework: Used to Shape and Steer Student Understanding

Students demonstrate different levels of understanding of material which often coincide with how diligent the students are with their daily preparation prior to class. Having them attempt homework problems prior to class enables them to be better prepared to ask specific questions about concepts and also better prepared to perform on exams. This paper will introduce “phased-array homework” whic...

Communication Technology Laboratory Fundamentals of Wireless Communications Homework 1 Solutions Problem 1 Identification of Ltv Systems

Fundamentals of Wireless Communications Homework 1 Solutions Handout date: April 1, 2014 Problem 1 Identification of LTV Systems 1. Suppose x stably identifiesQ. ForH1, H2 ∈ QwithH1x = H2xwe have 0 = H1x−H2x = (H1 −H2)x sinceH1, H2 are linear operators. Moreover,H1 −H2 ∈ Q. Since x stably identifiesQ, α‖H1 −H2‖H ≤ ‖(H1 −H2)x‖ = 0 with α > 0, which implies thatH1 −H2 = 0, i.e.,H1 = H2. 2. We sta...
