University of Delaware professor Leigh McLean has developed a new tool for measuring teachers’ emotional expressions and studying how these expressions affect their students’ attitudes toward learning. McLean uses this tool to gather new data showing emotional transmission between teachers and their students in fourth-grade classrooms.


McLean and co-author Nathan Jones of Boston University share the results of their use of the tool in a new article in Contemporary Educational Psychology. They found that teachers displayed far more positive emotions than negative ones. But they also found that some teachers showed high levels of negative emotions. In these cases, teachers’ expressions of negative emotions were associated with reduced student enjoyment of learning and engagement. These findings add to a compelling body of research highlighting the importance of teachers’ and students’ emotional experiences within the context of teaching and learning.


“Anyone who has been in a classroom knows that it is an inherently emotional environment, but we still don’t fully understand exactly how emotions, and especially the teachers’ emotions, work to either support or detract from students’ learning,” said McLean, who studies teachers’ emotions and well-being in the College of Education and Human Development’s School of Education (SOE) and Center Research in Education and Social Policy. “This new tool, and these findings, help us understand these processes more precisely and point to how we might provide emotion-centered classroom supports.”


Measuring teacher and student emotions

McLean and Jones collected survey data and video-recorded classroom observations from 65 fourth-grade teachers and 805 students in a Southwestern U.S. state. The surveys asked participants to report their emotions and emotion-related experiences — like feelings of enjoyment, worry or boredom — as well as their teaching and learning behaviors in mathematics and English language arts (ELA).


Using the new observational tool they developed — the Teacher Affect Coding System — McLean and Jones also assessed teachers’ vocal tones, body posturing, body movements and facial expressions during classroom instruction and categorized outward displays of emotion as positive, negative or neutral. For example, higher-pitched or lilting vocal tones were categorized as positive, while noticeably harsh or sad vocal tones were categorized as negative.


Overall, McLean and Jones found that teachers spent most of their instructional time displaying outward positive emotions. Interestingly though, they did not find any associations between these positive emotions and students’ content-related emotions or learning attitudes in ELA or math.


“This lack of association might be because outward positivity is the relative ‘norm’ for elementary school teachers, and our data seem to support that,” McLean said. “That’s not to say that teachers’ positivity isn’t important, though. Decades of research has shown us that when teachers are warm, responsive and supportive, and when they foster positive relationships with their students, students do better in almost every way. It could be that positivity works best when done in tandem with other important teacher behaviors or routines, or it could be that it is more relevant for different student outcomes.”


However, they did find that a small subset of teachers — about 10% — displayed notable amounts of negative emotions, with some showing negativity during as much as 80% of their instructional time. The students of these teachers reported reduced enjoyment and engagement in their ELA classes and reduced engagement in their math classes.


“We think that these teachers are struggling with their real-time emotion regulation skills,” McLean said. “Any teacher, even a very positive one, will tell you that managing a classroom of students is challenging, and staying positive through the frustrating times takes a lot of emotional regulation. Emotion regulation is a particularly important skill for teachers because children inherently look to the social cues of adults in their immediate environment to gauge their level of safety and comfort. When a teacher is dysregulated, their students pick up on this in ways that can detract from learning.”


Recommendations for supporting teacher well-being

Given the findings of their study, McLean and Jones make several recommendations for teacher preparation and professional learning programs. As a first step, they recommend that teacher preparation and professional learning programs share information about how negative emotions and experiences are a normal part of the teaching experience. As McLean said, “It’s okay to be frustrated!”


However, it is also important to be aware that repeated outward displays of negative emotion can impact students. McLean and Jones also suggest that these programs provide specific training to teachers on skills such as mindfulness and emotion regulation to help teachers manage negative emotions while they’re teaching.


“Logically, these findings and recommendations make complete sense,” said Steve Amendum, professor and director of CEHD’s SOE, which offers a K-8 teacher education program. “After working with many, many teachers, I often see teachers' enthusiasm or dislike for a particular activity or content area transfer to their students.”


McLean and Jones, however, emphasize that supporting teacher well-being can’t just be up to the teachers. Assistant principals, principals and other educational leaders should prioritize teacher wellness across the school and district. If teachers’ negative emotions in the classroom result in part from challenging working conditions or insufficient resources, educational leaders and policymakers should consider system-wide changes and supports to foster teacher well-being.

UD researchers launch open-source tool to boost global food security and water sustainability

Efficient water usage in agriculture is crucial for sustaining a growing human population. A better understanding of the systems that support agriculture, farmers and farmlands allows for food production to become more efficient and prosperous. That's what makes the Monthly Irrigated and Rainfed Cropped Areas Open Source (MIRCA-OS) dataset so important. MIRCA-OS offers high-resolution data on 23 crop classes — including maize, rice and wheat — and helps researchers, students and farmers examine irrigation, rainfall and croplands and how they interact with global water systems. Co-authored by Endalkachew (Endi) Kebede, a doctoral student in University of Delaware’s Department of Geography and Spatial Sciences, a recent paper focused on MIRCA-OS was published in Nature Scientific Data. Kyle Davis, assistant professor in the Department of Geography and Spatial Sciences and the Department of Plant and Soil Sciences, served as a co-author on the paper and coordinated the study. “We first developed a comprehensive data library of crop-specific irrigated and rainfed harvested areas for all countries,” Kebede said. “This involved two years of gathering data from a wide range of international, national and regional sources. Through this process, we produced a tabulated crop calendar, annual harvested area grids and monthly harvested area grids for all irrigated and rainfed crops.” “The amount of effort that Endi put in to gather, process and harmonize all of this data is truly incredible,” Davis said. “His effort is a very important contribution to the scientific and development communities.” Doctoral student Endalkachew Kebede (left) and Assistant Professor Kyle Davis. (Photo credit: University of Delaware) Cropland accounts for 13% of Earth's total habitable land, and the preservation of cropland is important in feeding the growing global population. “Crop production has been a widespread human activity for a few thousand years, and it has a huge role in global food security,” Kebede said. “But it also has unintended impacts on the environment, such as overutilization of water resources, pollution through rivers or the effects on soil and the environment.” MIRCA-OS can play a crucial role in helping to better understand croplands and agriculture, allowing the global population to be successfully fed while minimizing the agricultural effects on the environment. In addition to the data included on cropland and water resources, MIRCA-OS allows researchers to view social aspects like poverty and unemployment through an agricultural lens, creating a better understanding of the interconnectivity of agriculture and social issues. MIRCA-OS is an updated version of the earlier MIRCA2000 dataset. Kebede said the MIRCA2000 was released nearly two decades ago, so renewing the data gives users more accurate and timely information. Both datasets specialized in examining irrigation and rainfall, but the MIRCA-OS added two new complexities to their data. First, MIRCA-OS is open source, meaning it is publicly available for anyone to use, download, or modify. Kebede said the added accessibility allows the technology to contribute to anyone's work, whether it be a student, a researcher or a farmer. “Anybody can use, update it, or upscale it to the special skill they’re interested in,” Kebede said. “Some might use it for research, some might use it to create policies and some might use it to practice agriculture.” To arrange an interview with Davis, visit his profile and click on the contact button.
