   Science-based educational research increasingly supports the high value of active learning. The geospatial sciences incorporate active learning strategies such as field observation, experimental methods, hands-on learning, and the use of technology in the classroom. This session will demonstrate implementation of experiential learning methods such as field-based inquiry, metacognition, retrieval practice, and storytelling to promote comprehensive understanding and long-term learning in geoscience.

   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.

3. Connecting chemistry concepts with environmental context using student-built pH sensors

   https://doi.org/10.1080/10899995.2019.1702868  

   Seroy, Sasha K.; Zulmuthi, Hanis; Grünbaum, Daniel (December 2019, Journal of Geoscience Education)

   Educational research supports incorporating active engagement into K-12 education using authentic STEM experiences. While there are discipline-specific resources to provide students with such experiences, there are limited transdisciplinary opportunities that integrate engineering education and technological skill-building to contextualize core scientific concepts. Here, we present an adaptable module that integrates hands-on technology education and place-based learning to improve student understanding of key chemistry concepts as they relate to local environmental science. The module also supports disciplinary core ideas, practices, and cross-cutting concepts in accordance with the Next Generation Science Standards. We field-tested our module in three different high school courses: Chemistry, Oceanography and Advanced Placement Environmental Science at schools in Washington, USA. Students built spectrophotometric pH sensors using readily available electronic components and calibrated them with known pH reference standards. Students then used their sensors to measure the pH of local environmental water samples. Assessments showed significant improvement in content knowledge in all three courses relating to environmental relevance of pH, and to the design, use and environmental application of sensors. Students also reported increased self-confidence in the material, even when their content knowledge remained the same. These findings suggest that classroom sensor building and collection of environmental data increases student understanding and self-confidence by connecting chemistry concepts to local environmental settings.

4. “Whose story is being told?”: Local history, cultural heritage, and digital maps.

   Alexander, C; Brown, K; Weinburgh, M; Valverde, E (April 2023, Society for Information Technology and Teacher Education Conference Proceedings)

   Langran, E (Ed.)

   A critical outcome in social studies education is identity development, and an important component of this process is students establishing a sense of place in their communities, nation, and world. Using data from a southwestern city in the United States, researchers investigated the intersection of local history, identity development, and cultural heritage resources using GIS technology. The instructional unit in which students participated utilized a variety of geospatial technologies which facilitated the visualization of geographic concepts, field-based data collection of geocoded places, and creation of a digitally-mediated cultural heritage map, which allowed students to create a narrative around their cultural identity. The study followed an interpretive case study design. Based on the findings from this study, important implications emerged, which are valuable for both future research in this area, as well as for teachers who wish to replicate this pedagogical approach in their own teaching practice. The implications include the flexibility of geospatial technologies for addressing content-area concepts at all levels of the instructional unit, the potential of geospatial technologies for supporting student cultural identity development, and the value of school-university partnerships in promoting innovative teaching strategies in a high school classroom.

5. Critical thinking during science investigations: what do practicing teachers value and observe?

   https://doi.org/10.1080/13540602.2023.2191186  

   Butcher, Kirsten R.; Hudson, Michelle; Lane, McKenna; Larson, Madlyn (August 2023, Teachers and Teaching)

   This paper examines how practicing teachers approach and evaluate students’ critical thinking processes in science, using the implementation of an online, inquiry-based investigation in middle school classrooms as the context for teachers’ observations. Feedback and ratings from three samples of science teachers were analysed to determine how they valued and evaluated component processes of students’ critical thinking and how such processes were related to their instructional approaches and student outcomes. Drawing from an integrated view of teacher practice, results suggested that practicing science teachers readily observed and valued critical thinking processes that aligned to goal intentions focused on domain content and successful student thinking. These processes often manifested as components of effective scientific reasoning—for example, gathering evidence, analysing data, evaluating ideas, and developing strong arguments. However, teachers also expressed avoidance intentions related to student confusion and uncertainty before and after inquiry-based investigations designed for critical thinking. These findings highlight a potential disconnect between the benefits of productive student struggle for critical thinking as endorsed in the research on learning and science education and the meaning that teachers ascribe to such struggle as they seek to align their instructional practices to classroom challenges.
