The paper introduces the problem of robust head detection in collaborative learning environments. In such environments, the camera remains fixed while the students are allowed to sit at different parts of a table. Example challenges include the fact that students may be facing away from the camera or exposing different parts of their face to the camera. To address these issues, the paper proposes the development of two new methods based on Amplitude Modulation-Frequency Modulation (AM-FM) models. First, a combined approach based on color and FM texture is developed for robust face detection

Human activity classification remains challenging due to the strong need to eliminate structural noise, the multitude of possible activities, and the strong variations in video acquisition. The current paper explores the study of human activity classification in a collaborative learning environment.This paper explores the use of color based object detection in conjunction with contextualization of object interaction to isolate motion vectors specific to each human activity. The basic approach is to make use of separate classifiers for each activity. Here, we consider the detection of typing

In this paper, we summarize some of the lessons learned from the Advancing Out-of-School Learning in Mathematics and Engineering (AOLME) project. The AOLME project uses an integrated curriculum that relies on the use of basic concepts from middle-school mathematics to teach the foundations of image and video representations. The middle-school students, mostly from underrepresented groups, learn how to program their own video representations using Python libraries running on the Raspberry Pi. Overall, we have found that the students enjoy participating in the project.

High school capstone courses—culminating educational experiences for seniors as they conclude their formal high school education—have become increasingly popular across the nation, particularly in New England. The STEMStarter Capstone was designed to help Connecticut high schools meet new accreditation standards from the New England Association of Schools and Colleges (NEASC) and graduation requirements that include a mastery-based learning project. Standard 2 of the NEASC 2020 Standards (2018) for school accreditation states: “Students are active learners and have the opportunity to lead

Pre-post data from 764 treatment and 553 comparison middle school students from nine US states were analyzed to examine STEM-related attitudes and dispositions aligning with climate change beliefs and intentions, and acquisition of energy and environmental science content knowledge. Findings were that at least seven non-cognitive variables contribute between eight and fifteen percent of the beliefs, intentions, and knowledge acquisitions of interest in this study, in linear combinations of subsets of the variables. Implications of these findings for promoting interest in STEM are discussed

This research report presents the results of a STEM summer program on robotics and game design. The program was part of a three-year study funded by the National Science Foundation. Children in grades four through six participated in a two-week summer camp in 2015 to learn STEM by engaging in LEGO® EV3 robotics and computer-based games using Scalable Game Design. Twenty-eight students participated in the study that took place in a small urban community in the Rocky Mountain West. This paper reports on the results of this part of the study, specifically, how children’s computational thinking

This research report presents the final year results of a three-year research project on computational thinking (CT). The project, funded by the National Science Foundation, involved training teachers in grades four through six to implement Scalable Game Design and LEGO® EV3 robotics during afterschool clubs. Thirty teachers and 531 students took part in the Year-3 study that blended game design and robotics. Eight of these teachers and 98 students participated in a large urban city in Pennsylvania, while the remaining 22 teachers and 433 students participated in rural Wyoming. This paper

Making and tinkering is currently gaining traction as an interdisciplinary approach to education. However, little is known about how these activities and explorations in formal and informal learning spaces address the content and skills common to professionals across science, technology, engineering, and mathematics. As such, the purpose of this qualitative study was to examine how youth were engaged in the eight science and engineering practice outlined within the US Next Generation Science Standards within an informal learnin environment utilizing principles of tinkering within the daily
