Scientific education provides a set of tools to make sense of a complex world by teasing out complicated cause-and-effect relationships, such as the elimination of effects of confounding factors in controlled experiments. There is evidence that depth of understanding of controlled experiments is lacking among undergraduate science students despite exposure to controlled experiments in courses.

We investigated whether an active learning approach, facilitated by a personal response system, would lead to improved student engagement and learning outcomes in large-group physiology lectures for undergraduate science students. We focused on encouraging students' active learning in lectures, whereas previous studies have made more use of audience response technology during lectures for formative or summative assessment. Students voluntarily answered questions posed during lectures with their personal response system (clickers), with individual answers automatically collated for immediate histogram display. This feedback then dictated the focus of followup discussions in the lecture. Student and instructor attitudes were surveyed through voluntary interviews with student responses correlated with their degree of clicker participation and individual exam results. Active lectures were found to increase both student motivation and engagement. Students who participated in answering questions achieved better results than students who chose not to. Students with the lowest scores in a prerequisite course (previous semester physiology exam marks of < 60%) showed significantly better outcomes from the use of clickers than both middle-achieving (60-75%) and high-achieving (>75%) entry students. Significant improvement was evident in both mid- and end-semester exam results compared with student cohorts from preceding years, although this could also be influenced by many other factors. Increased student engagement and the immediate feedback obtained during lectures were advantages commonly noted by lecturing staff.

Abstract Background Seminal reports, based on recommendations by educators, scientists, and in collaboration with students, have called for undergraduate curricula to engage students in some of the same practices as scientists—one of which is communicating science with a general, non-scientific audience (SciComm). Unfortunately, very little research has focused on helping students develop these skills. An important early step in creating effective and efficient curricula is understanding what baseline skills students have prior to instruction. Here, we used the Essential Elements for Effective Science Communication (EEES) framework to survey the SciComm skills of students in an environmental science course in which they had little SciComm training. Results Our analyses revealed that, despite not being given the framework, students included several of the 13 elements, especially those which were explicitly asked for in the assignment instructions. Students commonly targeted broad audiences composed of interested adults, aimed to increase the knowledge and awareness of their audience, and planned and executed remote projects using print on social media. Additionally, students demonstrated flexibility in their skills by slightly differing their choices depending on the context of the assignment, such as creating more engaging content than they had planned for. Conclusions The students exhibited several key baseline skills, even though they had minimal training on the best practices of SciComm; however, more support is required to help students become better communicators, and more work in different contexts may be beneficial to acquire additional perspectives on SciComm skills among a variety of science students. The few elements that were not well highlighted in the students’ projects may not have been as intuitive to novice communicators. Thus, we provide recommendations for how educators can help their undergraduate science students develop valuable, prescribed SciComm skills. Some of these recommendations include helping students determine the right audience for their communication project, providing opportunities for students to try multiple media types, determining the type of language that is appropriate for the audience, and encouraging students to aim for a mix of communication objectives. With this guidance, educators can better prepare their students to become a more open and communicative generation of scientists and citizens.

A desired outcome of education reform efforts is for undergraduates to effectively integrate knowledge across disciplines in order to evaluate and address real-world issues. Yet there are few assessments designed to measure if and how students think interdisciplinarily. Here, a sample of science faculty were surveyed to understand how they currently assess students’ interdisciplinary science understanding. Results indicate that individual writing-intensive activities are the most frequently used assessment type (69%). To understand how writing assignments can accurately assess students’ ability to think interdisciplinarily, we used a preexisting rubric, designed to measure social science students’ interdisciplinary understanding, to assess writing assignments from 71 undergraduate science students. Semistructured interviews were conducted with 25 of those students to explore similarities and differences between assignment scores and verbal understanding of interdisciplinary science. Results suggest that certain constructs of the instrument did not fully capture this competency for our population, but instead, an interdisciplinary framework may be a better model to guide assessment development of interdisciplinary science. These data suggest that a new instrument designed through the lens of this model could more accurately characterize interdisciplinary science understanding for undergraduate students.

Researchers have established improved methods for undergraduate science and engineering education, yet these efforts often overlook the personal meaning students find in their work. Institutions of higher learning should support the creation of personal meaning along with content mastery, aspects that are both included in arts education. The authors argue that STEM educators must work to overcome student perception that content mastery and personal meaning sit at odds. The authors provide an example of a technical course that achieves these goals as well as evidence that it is possible to foster connection while developing content mastery.

Fake news and alternative science are increasingly popular topics of conversation in the public sphere and the classroom due to increasingly far-reaching social media and a shifting political climate. Promoting scientific literacy by providing opportunities for students to evaluate reports of contentious scientific issues and analyze the underlying factors that influence public perception of science is necessary for the development of an informed citizenry. This article describes a three-part learning activity useful for engaging biology students in evaluating the accuracy of science-related news reports, and reflecting upon the ways that social cues, religion, and political ideologies shape perception of science. These activities are appropriate for teaching about climate change, evolution, vaccines, and other important contemporary scientific issues in upper-level high school and undergraduate science courses.

Achieving science undergraduate programs learning outcomes relies on the students’ proficiency in the language of instruction, a challenge that many policymakers ignore. This study is to understand the influence of English as a medium of instruction (EMI) policy in four undergraduate science programs, namely, Biology, Chemistry, Physics, and Mathematics, in Saudi Arabia. The data were collected from the following groups of participants: 1461 science alumni records, 769 current undergraduate science students’ surveys, and 111 science university instructors’ surveys. The results of alumni records indicated that grades of the intensive English program in the first year predict the alumni cumulative grade point average (GPA) once they finish their four-year program. The results demonstrated that the higher is the alumni’s English proficiency, the better is their cumulative GPA. The results of the current science students’ questionnaire showed their preferred language of instruction could be predicted by their attitudes and society’s attitudes. Most of these students preferred to learn sciences in their native language (Arabic), which contradicted the policy of the current program. The instructors’ questionnaire results showed that instructors held divergent perspectives on the usage of EMI and students’ native language in the undergraduate science programs. To conclude, educationists and programs policymakers need to locate more attention and interventions toward the language of instruction. It is also recommended that universities provide science students with more English courses. Science students should also have English for science purposes courses to familiarize them with the science terms and prepare them to read science materials.

The Vision and Change in Undergraduate Biology Education final report challenged institutions to reform their biology courses to focus on process skills and student active learning, among other recommendations. A large southeastern university implemented curricular changes to its majors’ introductory biology sequence in alignment with these recommendations. Discussion sections focused on developing student process skills were added to both lectures and a lab, and one semester of lab was removed. This curriculum was implemented using active-learning techniques paired with student collaboration. This study determined whether these changes resulted in a higher gain of student scientific literacy by conducting pre/posttesting of scientific literacy for two cohorts: students experiencing the unreformed curriculum and students experiencing the reformed curriculum. Retention of student scientific literacy for each cohort was also assessed 4 months later. At the end of the academic year, scientific literacy gains were significantly higher for students in the reformed curriculum (p = 0.005), with those students having double the scientific literacy gains of the cohort in the unreformed curriculum. Retention of scientific literacy did not differ between the cohorts.
