Economic projections reveal a need for one million more Science, Technology, Engineering, and Math (STEM) professionals over the next decade than the United States is producing at the current rate. As a result, STEM education is a major focus of recent legislation and funding in Congress as the number of STEM professionals is inadequate to support innovation and the ever-changing economy. In response to the urgent need for more competitive STEM professionals, there has been a widespread implementation of workshops, organizations, and school programs aimed at amplifying K-12 student STEM literacy and interest. Some programs are even created to specifically reach and attract women and unrepresented minorities to STEM. Despite the increase in outreach programs, they remain limited to a straightforward discussion of a narrow scope of STEM topics. Many workshops and programs continue to validate the positive impacts of utilizing hands-on projects but cease to inform about broader STEM applications through the exploration and integration of storytelling, culture, and community. Professors and students from the Liberal Art and Engineering Studies program at California Polytechnic State University, San Luis Obispo founded the Seeds in STEM organization to develop K-12 STEM workshops that incorporate a participants’ culture and community in the learning process per a storyline that guides the participants through several STEM activities. This paper discusses the impact of adding a workshop activity that introduces motion capture technologies and their application to the Seeds in STEM workshop held on April 30th, 2022. The results collected from the activity via three forms of assessment demonstrate generally positive trends in the attitudes of the participants regarding STEM topics and the careers encompassed by STEM.

Uncertainty is ubiquitous in life, and learning is an activity particularly likely to be fraught with uncertainty. Previous research suggests that students and teachers struggle in their attempts to manage the psychological experience of uncertainty and that students often fail to experience uncertainty when uncertainty may be warranted. Yet, few educational researchers have explicitly and systematically observed what students do, their behaviors and strategies, as they attempt to manage the uncertainty they experience during academic tasks. In this study I investigated how students in one fifth grade class managed uncertainty they experienced while engaged in collaborative robotics engineering projects, focusing particularly on how uncertainty management was influenced by task structure and students’ interactions with their peer collaborators. The study was initiated at the beginning of instruction related to robotics engineering and preceded through the completion of several long-term collaborative robotics projects, one of which was a design project. I relied primarily on naturalistic observation of group sessions, semi-structured interviews, and collection of artifacts. My data analysis was inductive and interpretive, using qualitative discourse analysis techniques and methods of grounded theory. Three theoretical frameworks influenced the conception and design of this study: community of practice, distributed cognition, and complex adaptive systems theory. Uncertainty was a pervasive experience for the students collaborating in this instructional context. Students experienced uncertainty related to the project activity and uncertainty related to the social system as they collaborated to fulfill the requirements of their robotics engineering projects. They managed their uncertainty through a diverse set of tactics for reducing, ignoring, maintaining, and increasing uncertainty. Students experienced uncertainty from more different sources and used more and different types of uncertainty management strategies in the less structured task setting than in the more structured task setting. Peer interaction was influential because students relied on supportive social response to enact most of their uncertainty management strategies. When students could not garner socially supportive response from their peers, their options for managing uncertainty were greatly reduced. / text

Human footwear is not yet designed to optimally relieve pressure on the heel of the foot. Proper foot pressure assessment requires personal training and measurements by specialized machinery. This research aims to investigate and hypothesize about Preferred Transition Speed (PTS) and to classify the gait phase of explicit variances in walking patterns between different subjects. An in-shoe wearable pressure system using Android application was developed to investigate walking patterns and collect data on Activities of Daily Living (ADL). In-shoe circuitry used Flexi-Force A201 sensors placed at three major areas: heel contact, 1st metatarsal, and 5th metatarsal with a PIC16F688 microcontroller and Bluetooth module. This method provides a low-cost instantaneous solution to both wear and records plantar foot simultaneously. Data acquisition used internal local memory to store pressure logs for offline data analysis. Data processing used the perpendicular slope to determine peak pressure and time of index. Statistical analysis can utilize to discover foot deformity. The empirical results in one subject showed weak linearity between normal and fast walk and a significant difference in body weight acceptance between normal and slow walk. In addition, T-test hypothesis testing between two healthy subjects, with , illustrated a significant difference in their Initial Contact pressure and no difference between their peak-to-peak time interval. Preferred Transition Speed versus VGRF was measured in 19 subjects. The experiments demonstrated that vertical GRF averagely increased 18.46% when the speed changed from 50% to 75% of PTS with STD 4.78. While VGRF increased 21.24% when the speed changed from 75% to 100% of PTS with STD 7.81. Finally, logistic regression between 12 healthy subjects demonstrated a good classification with 82.6% accuracy between partial foot bearing and their normal walk.

Diante do crescente desenvolvimento da tecnologia da informação e da comunicação, o sistema educacional vem gradualmente modificando as estratégias de ensino-aprendizagem, adaptando para tanto, os tradicionais procedimentos e técnicas didáticas aos instrumentos tecnológicos fornecidos pelos ambientes virtuais de aprendizagem. O processo de avaliação e acompanhamento da aprendizagem nestes ambientes requer o uso de novas estratégias de ensino que congregue os recursos tecnológicos e a intervenção positiva do professor/tutor. Propõe-se um modelo de design instrucional estendido do \"Integrative Learning Design Framework On-line\" (ILDF) sob o enfoque da taxonomia dos objetivos educacionais de Bloom e do ciclo de aprendizagem vivencial de Kolb adaptado por Belhot para uma disciplina de pós-graduação em Engenharia de Produção. Este modelo foi implementado e avaliado na disciplina \"Metodologia de Pesquisa para Engenharia\" oferecida no primeiro semestre de 2008 para 14 alunos de pós-graduação de Engenharia de Produção e envolveu o planejamento, elaboração e disposição do material didático e de atividades orientadas no ambiente virtual de aprendizagem - Moodle. Sugere-se um protocolo de organização de estratégias dialógicas como os fóruns de discussões on-line e uma rubrica avaliativa sobre a qualidade, quantidade, relevância, forma das mensagens e dos níveis de conhecimento cognitivo dos alunos para a construção do conhecimento colaborativo. Os resultados revelam que, as estratégias dialógicas e exploratórias adotadas, promoveram a evolução dos alunos com relação aos níveis de desenvolvimento cognitivo e da aprendizagem vivencial e contribuíram para a construção do conhecimento de forma colaborativa e significativa. / Faced with increasing development of information technology and communication, the educational system is gradually changing the teaching-learning strategies, adapting to both the traditional procedures and techniques for teaching technologica tools provided by the virtual environment of learning. The evaluation process and monitoring of learning in this environment require the use of new teaching strategies for bringing together the technological resources and positive intervention of the teacher/tutor. The present work proposes a model of instructional design extended from the \"Integrative Learning Design Framework On-line\" (ILDF) under the focus of the taxonomy of educational objectives of Bloom and the Kolb´s cycle of experiential learning adapted by Belhot to a discipline of Production Engineering postgraduate program. This model was implemented and assessed during the course \"Research Methodology for Engineering\" offered in the first half of 2008 to 14 postgraduate students of Production Engineering and it involved the planning, preparation and disposal of teaching material and activities geared to virtual environment of learning - Moodle. It is suggested a protocol for organizing dialogical strategies as forums for discussions on-line and a evaluative rubric about quality, quantity, relevance, and the message structures, and the levels of cognitive knowledge of the students for the construction of collaborative knowledge. The results show that the dialogical and exploratory strategies adopted, have contributed to the progress of students with respect to the levels of cognitive development and the experiential learning and they have also contributed to the construction of knowledge in a collaborative and significant way.

O presente trabalho apresenta uma proposta para a criação de um ambiente web colaborativo responsável pela troca das melhores práticas de planejamento de aulas utilizadas pelos especialistas e educadores, agrupados pelo que chamaremos de artefatos pedagógicos ou padrões pedagógicos, considerados a menor unidade divisível de uma aula. O planejamento será pautado pelo conceitual de design instrucional, que proporciona o encadeamento de forma simplificada e em ordem cronológica de todos os conteúdos previstos a execução de um curso ou de uma disciplina. Com a utilização da ferramenta em ambiente compartilhado (web), será mostrado que o efetivo planejamento de um simples objetivo de aprendizagem ou até mesmo a de um conteúdo mais amplo, por intermédio da apresentação linear e cronológica de todos os artefatos pedagógicos, levará à uma visão geral e completa da composição dos assuntos abordados. Neste momento, será possível visualizar por intermédio de relatórios, dentre as funcionalidades da própria ferramenta, o formato de matriz de design instrucional, um dos produtos essenciais da fase de planejamento de um curso. Para a criação dos artefatos pedagógicos de forma compartilhada será utilizado um protótipo de interface gráfica conduzido por conceitos de arquitetura de informação e usabilidade. Com o objetivo de transformar o protótipo em uma ferramenta, na fase de implementação será utilizada a estrutura de um sistema de gerenciamento de conteúdo, capaz de simplificar esta etapa extremamente complexa. A aplicação por meio do estudo de caso será feita através de uma disciplina do curso de pós-graduação, com foco nas tecnologias de ensino de engenharia, ilustrando a contribuição do presente trabalho e dando condições de um real e efetivo resultado da metodologia utilizada. A sua efetiva consolidação será obtida pelo estabelecimento de uma avaliação de reação aplicada entre o grupo de alunos do referido estudo de caso. / This paper presents , in relation to new forms of teaching and learning , a proposal for the creation of a collaborative web environment responsible for the exchange of best practice techniques for classroom used by educators and experts , grouped by which we will pedagogical patterns or pedagogical artifacts , and grounded in the concepts of \" instructional design \" , which can be considered as a structure that provides to the heterogeneous audience, since experts in education and technology and students interested in a particular subject to plan a simplified form and measurable their respective courses , modules , and related disciplines . With the use of the tool in a shared environment will be shown that the effective planning of a single learning object or even a broader content, through linear and chronological presentation of all educational artifacts will lead to an overview and complete the composition of the subjects covered, coming to provide in one aspect of the tool itself, the format of an instructional design matrix, one of the key products of the planning phase of a course. For the creation of educational artifacts in a shared way, will be used a graphical interface prototype concepts outlined by information architecture and usability, and its last one implementation in a development framework designed for what we call content management system. The application, by case study, will be taken through a course in the graduate with a focus on teaching engineering technologies, illustrating the contribution of this work and giving conditions for a real and effective result of the methodology used, consolidated by the establishment of a reaction evaluation performed between the group of students of that case study.
