Making a First Impression: Exploring What Instructors Do and Say on the First Day of Introductory STEM Courses.

ABSTRACT: Student impressions formed during the first day of class can impact course satisfaction and performance. Despite its potential importance, little is known about how instructors format the first day of class. Here, we report on observations of the first day of class in 23 introductory science, technology, engineering, and math (STEM) courses. We first described how introductory STEM instructors structure their class time by characterizing topics covered on the first day through inductive coding of class videos. We found that all instructors discussed policies and basic information. However, a cluster analysis revealed two groups of instructors who differed primarily in their level of STEM content coverage. We then coded the videos with the noncontent Instructor Talk framework, which organizes the statements instructors make unrelated to disciplinary content into several categories and subcategories. Instructors generally focused on building the instructor-student relationship and establishing classroom culture. Qualitative analysis indicated that instructors varied in the specificity of their noncontent statements and may have sent mixed messages by making negatively phrased statements with seemingly positive intentions. These results uncovered variation in instructor actions on the first day of class and can help instructors more effectively plan this day by providing messages that set students up for success.

Project description:BackgroundRigorous assessment of medical knowledge and technical skill inspires learning, reinforces confidence, and reassures the public. Identifying curricular effectiveness using objective measures of learning is therefore crucial for competency-oriented program development in a learner-centric educational environment. The aim of this study was to determine whether various measures of learning, including class-average normalized gain, can be used to assess the effectiveness of a one-day introductory bronchoscopy course curriculum.MethodsWe conducted a quasi-experimental one-group pre-test/post-test study at the University of California, Irvine. The group comprised 24 first-year pulmonary and critical care trainees from eight training institutions in southern California. Class-average normalized gain, single-student normalized gain, absolute gain, and relative gain were used as objective measures of cognitive knowledge and bronchoscopy technical skill learning. A class-average normalized gain of 30% was used to determine curricular effectiveness. Perceived educational value using Likert-scale surveys and post-course questionnaires was determined during and 3 months after course participation.ResultsMean test scores of cognitive knowledge improved significantly from 48 to 66% (p = 0.043). Absolute gain for the class was 18%, relative gain was 37%, class average normalized gain <g> was 34%, and the average of the single-student normalized gains g(ave) was 29%. Mean test scores of technical skill improved significantly from 43 to 77% (p = 0.017). Absolute gain was 34%, relative gain was 78%, class average normalized gain <g> was 60%, and the average of the single-student normalized gains g(ave) was 59%. Statistically significant improvements in absolute gain were noted in all five elements of technical skill (p < 0.05). Likert-scale surveys, questionnaires, and surveys demonstrated strong perceived educational value.ConclusionThe effectiveness of a one-day introductory bronchoscopy curriculum was demonstrated using a pre-test/post-test model with calculation of normalized gain and related metrics.
