Using Demonstrations during Lectures

Prop Demonstrations in Biology Lectures Facilitate Student Learning and Performance†

Science students can benefit from visual aids. In biology lectures, visual aids are usually limited to tables, figures, and PowerPoint presentations. In this IRB-approved study, we examined the effectiveness of the use of five prop demonstrations, three of which are at the intersection of biology and chemistry, in three community college biology courses. We hypothesized that students' performan...

Using Lecture Demonstrations to Visualize Biological Concepts

INTRODUCTION The use of visual aids in biology has traditionally focused on laboratory activities and demonstrations (3, 6, 8, 12, 15–18). However, a limited number of authors have suggested activities suitable for lectures. Such activities reinforce the concepts taught and require less equipment, time, and expense than laboratory activities Moreover, simple demonstrations are easy for students...

Using Human Demonstrations to Improve Reinforcement Learning

This work introduces Human-Agent Transfer (HAT), an algorithm that combines transfer learning, learning from demonstration and reinforcement learning to achieve rapid learning and high performance in complex domains. Using experiments in a simulated robot soccer domain, we show that human demonstrations transferred into a baseline policy for an agent and refined using reinforcement learning sig...

Acappella synthesis demonstrations using RWC music database

A series of demonstrations of synthesized acappella songs based on an auditory morphing using STRAIGHT [5] will be presented. Singing voice data for morphing were extracted from the RWCmusic database of musical instrument sound. Discussions on a new extension of the morphing procedure to deal with vibrato will be introduced based on the statistical analysis of the database and its effect on syn...
