Title: Utilization of Remote Access Electron Microscopes to Enhance Technology Education and Foster STEM Interest in Preteen Students
Remote access technology in STEM education fills dual roles as an educational tool to deliver science education (Educational Technology) and as a means to teach about technology itself (Technology Education). A five-lesson sequence was introduced to 11 and 12-year-old students at an urban school. The lesson sequences were inquiry-based, hands-on, and utilized active learning pedagogies, which have been implemented in STEM classrooms worldwide. Each lesson employed a scanning electron microscope (SEM) and energy dispersive spectroscopy (EDS) accessed remotely. Students were assessed using multiple-choice questions to ascertain (1) technology education learning gains: did students gain an understanding of how electron microscopes work? and (2) educational technology learning gains: did students gain a better understanding of lesson content through use of the electron microscope? Likert-item surveys were developed, distributed, and analyzed to established how remote access technology affected student attitudes toward science, college, and technology. Participating students had a positive increase in attitudes toward scientific technology by engaging in the lesson sequences, reported positive attitudes toward remote access experiences, and exhibited learning gains in the science behind the SEM technology they accessed remotely. These findings suggest that remote experiences are a strong form of technology education, but also that future research could explore ways to strengthen remote access as an educational technology (a tool to deliver lesson content), such as one-on-one engagement. This study promotes future research into inquiry-based, hands-on, integrated lessons approach that utilize educational technology learning through remote instruments as a pedagogy to increase students’ engagement with and learning of the T in STEM.  more » « less

    Use of geospatial technology in higher education facilitates student engagement, promotes deeper understanding of material, and supports inquiry-based learning. However, technology must be applied strategically to generate optimal results. While use of web-based interactive modules and short video are constructive in curriculum, it is beneficial to combine this with exposure to hands-on, experimental, field-based technologies. Experiential learning with technology in the physical environment allows students to understand both the challenges and achievements of scientific investigation. This creates a more comprehensive understanding of science as an iterative process of experimentation and investigation and enrichens course material. This paper explores the uniquely advantageous opportunity Geography educators have to combine classroom-based technology with field-based educational experiences. Classroom use of Geographic Information Systems (GIS) and Remotely Sensed data is increasingly accessible with abundant free educational resources. In addition, field-based use of technology can promote location awareness and spatial critical thinking with the use of GPS-based activities. GPS-based educational units also highlight the growing field of citizen science and can be designed as service-based learning opportunities. Use of highly affordable micro unmanned aerial vehicles (UAV) demonstrates data collection procedures. In addition, exposure to Surveying techniques and the field of Geomatics highlights real-world applications of geographic technology. We discuss the use of geospatial technologies in introductory and advanced higher education courses and examine how technology can encourage access to scientific inquiry throughout the student population.

    ABSTRACT: In this era of information abundance and digital connectivity, educational videos are a transformative and widely used resource in STEM higher education. Much of what is known about the effective use of educational videos comes from analyzing videos used for content delivery and the impacts on knowledge gains or behavioral engagement with videos. Less is known about how videos may impact students’ affective learning experiences, feelings, and attitudes or how to effectively use videos in science education beyond just as a content-delivery tool. This study explored the impact of three distinct video styles: a whiteboard animation, a recorded discovery lecture by one of the discoverers, and a documentary short film featuring both discoverers in conversation on student outcomes in a large-enrollment undergraduate biology class. Students were randomized to watch one of these three formats, all covering the same scientific content (i.e., the Meselson and Stahl experiment), followed by a post-video survey. The documentary film, “The Most Beautiful Experiment,” which integrated interpersonal storytelling and informal dialog, had the most significant impact on outcomes related to affective learning, including science identity, attitudes about biology, speaker relatability, and emotional engagement. No significant differences in knowledge gains were observed across video styles. This study highlights the potential of personalized and embodied video formats to enrich STEM education and warrants further research into their broader applications.

    Abstract BackgroundWith the increasing popularity of distance education, how to engage students in online inquiry‐based laboratories remains challenging for science teachers. Current remote labs mostly adopt a centralized model with limited flexibility left for teachers' just‐in‐time instruction based on students' real‐time science practices. ObjectivesThe goal of this research is to investigate the impact of a non‐centralized remote lab on students' cognitive and behavioural engagement. MethodsA mixed‐methods design was adopted. Participants were the high school students enrolled in two virtual chemistry classes. Remote labs 2.0, branded as Telelab, supports a non‐centralized model of remote inquiry that can enact more interactive hands‐on labs anywhere, anytime. Teleinquiry Instructional Model was used to guide the curriculum design. Students' clickstreams logs and instruction timestamps were analysed and visualized. Multiple regression analysis was used to determine whether engagement levels influence their conceptual learning. Behavioural engagement patterns were corroborated with survey responses. Results and ConclusionsWe found approximate synchronizations between student–teacher–lab interactions in the heatmap. The guided inquiry enabled by Telelab facilitates real‐time communications between instructors and students. Students' conceptual learning is found to be impacted by varying engagement levels. Students' behavioural engagement patterns can be visualized and fed to instructors to inform learning progress and enact just‐in‐time instruction. ImplicationsTelelab offers a model of remote labs 2.0 that can be easily customized to live stream hands‐on teleinquiry. It enhances engagement and gives participants a sense of telepresence. Providing a customizable teleinquiry curriculum for practitioners may better prepare them to teach inquiry‐based laboratories online.

    There have been many questions and concerns raised by educators about how advanced technology students will adapt to remote learning during the COVID era. What will technician students’ academic engagement and persistence be like, and how will online learning affect their educational outcomes? What do technician students like about remote learning and what do they find challenging? What does online learning mean for hands-on applied and experiential learning, which are hallmarks of technical education programs? This paper explores pilot survey data collected in Florida from advanced technology students at two-year colleges. Five primary areas covered in the survey include enrollment status, access to technology, experience using a Learning Management System and learning online, impact on applied and experiential learning, and students’ background information. Key findings include decreased interaction between peers, increased reliance on instructors, and a significant decline in experiential learning such as labs, group projects, demonstrations, problem-based learning, and service-learning. The majority of students report feeling worried about making progress toward their degree, and about half worried about completing the semester. Two benefits students identified as having access to course materials all the time through the LMS and the flexibility of remote learning. Findings also show that technician students are quite diverse by way of age, partner status, having a family, race-ethnicity, employment status, and educational background. About one-third of students who responded are women. This paper concludes with several recommendations about the application of these research findings to address challenges technician students face learning online, including specific actions that instructors and programs can pursue to help retain students and provide support through the completion of degree programs.

    In pre-college levels, integrated science, technology, engineering, and mathematics (STEM) are often taught by science or mathematics teachers. These teachers lack the engineering and technology background and they do not necessarily use project-based and inquiry-oriented instructional strategies. To close the gap in the qualified STEM education teacher workforce, the authors developed and piloted a novel course to train preservice STEM teachers to effectively employ project-based and inquiry-oriented teaching strategies at pre-college levels. This 3-credit research and design experience course was piloted in the Spring 2023 semester. The preservice STEM teachers, enrolled in the course, engaged in hands-on activities, engineering project-based training, inquiry-based learning techniques through research training, makerspace training, field experience, and mentorship. The course comprised two parts. In part I, the students received research training. In part II, the students engaged in engineering design and makerspace professional development. In this paper, we report on the course design elements and the impact of the course activities on students’ self-efficacy in teaching STEM subjects using emerging technology, as well as their teaching approaches and understanding of student learning. The authors conducted a mixed methods study and collected both qualitative and quantitative data. Preliminary results of the multiyear study are presented. Initial findings indicate a heightened confidence of the students in their ability to deliver STEM content in secondary classrooms. Students improved their teaching approaches and reported positive experiences with the course.
