The 2020-2021 academic year was unlike any other. After nationwide school closures during the spring of 2020, schools reopened in the fall using combinations of in-person, hybrid, and remote learning models. Teachers had to adapt to unexpected conditions, teaching in unprecedented ways, using synchronous and asynchronous instruction, while also being challenged to establish connections with students, families, and colleagues. Health concerns added to the mix as some teachers went back to in-person education during the height of the pandemic. As a result, Twitter jbmcgee A RAND survey, fielded in early January 2021, found that We study data from 1,045 teachers from a survey administered in March 2021. About 30% of teachers in our sample reported teaching fully remote for the majority of the school year, 49% reported that they taught in a hybrid model, and 21% reported teaching fully in person. A large majority of teachers in our sample (71%) reported they had to switch instructional models at least once during the 2020-2021 school year, and the average teacher switched models twice. To see how teachers’ attitudes may have changed through the pandemic, we compare the March 2021 data to responses to a pre-pandemic survey of 5,464 teachers administered mid-February to mid-March 2020. We find that, during the pandemic, teachers have become less certain that they would work a full career in the classroom. In March 2020, 74% of teachers reported that they expected to work as a te...

The field of statistics is concerned with collecting, analyzing, interpreting, and presenting data. In an education setting, statistics is important for the following reasons: Reason 1: Statistics allows educators to understand student performance using descriptive statistics. Reason 2: Statistics allows educators to spot trends in student performance using data visualizations. Reason 3: Statistics allows educators to compare different teaching methods using hypothesis tests. In the rest of this article, we elaborate on each of these reasons. Reason 1: Understand Student Performance Using Descriptive Statistics describe data. In an education setting, a teacher might calculate the following descriptive statistics for students in her class: • The mean score on a certain exam. • The standard deviation of scores on a certain exam. • The range of scores on a certain exam. • The percentage of students who passed a certain exam. • The 90th percentile of scores on a certain exam. Using these metrics, the teacher can gain a better understanding of how the students in her class performed on a certain exam. She can then decide if she needs to change her teaching method if too few students pass the exam or perhaps offer additional tutoring opportunities for students who score low on the exam, etc. Note: These types of descriptive statistics are used at every level of education. For example, a principal can use descriptive statistics to monitor exam scores of students in an entire scho...
