High-school students in university research labs? Implementing an outreach model based on the ‘science as inquiry’ approach

In this study we designed, implemented, and evaluated an outreach programme for high-school biology students rooted in the ‘science as inquiry’ approach. Accordingly, students learn about science from experts in the field, as well as through in-class exposure to the history and philosophy of science. Our sample consisted of 11th graders (n?=?497), ages 16–17, attending advanced biology classes. Our goal was to determine whether this programme had a significant effect on students’ understanding of the ‘nature of science’ (NOS) and on their attitudes towards science. Using a controlled pre-post research design, we asked participants to complete a Likert-like questionnaire. Also, we conducted post-programme semi-structured interviews with 35 of the participants. Results show that completion of the programme significantly enhanced participants’ NOS understanding and improved their attitudes towards science. Participants expressed a deep level of NOS understanding and explicitly stated that the field visits to experts’ labs had changed their attitude towards science. We believe that our outreach programme can be adapted for teaching other sciences and for societies worldwide, as long as there is access to university laboratories and researchers willing to interact with young citizens and potential future scientists.     

How to Generate Student Excitement in Science

The Draw-an-Archaeologist Test (DART) is an easy way to elieit students' conceptions about archaeology and can be adapted to other subject matter. When implemented as the first activity of an archaeology unit, it provides a starting point for introducing archaeology and addressing students' misconceptions about it. In this drawing activity, students are asked to describe not only what archaeologists do, but who they are in terms of gender and ethnicities. This activity can be used to generate a discussion on equity and to access differences between genders and ethnicities, which fulfills one of the national science education standards for the history and nature of science.     

The Capture: Kidnapping Students’ Interests Using the Guardians of Ga’Hoole

This project describes a fourth-grade unit that integrated science and language arts using the book The Capture as a focal point. During the unit, students engaged in science activities and language arts lessons that focused on owls. Students conducted investigations that helped them develop a deeper understanding of the adaptations of several owl species. Additionally, the fourth-graders developed their language arts skills for conducting research, using figurative language, and presenting information. Examples of helpful resources and student work are included.     

Using Amphibians and Reptiles to learn the Process of Science

The National Research Council's document, Inquiry and the National Science Education Standards (2000) describes an elementary science classroom as one that is composed of learners who are engaged in scientific processes. In such a setting, children ask real-world questions and seek real-world solutions. As students pursue their inquiries, they often move away from science textbooks, and they implement mathematical skills, read literature, conduct research in electronic databases, write stories, and so forth in a larger context. What was originally a regular science lesson becomes an opportunity for integration across the curriculum. This article describes an integrated unit on bats and specifically addresses the National Science Education Standards.     

Using Inquiry to Learn about Soil: A Fourth Grade Experience

In this article, we describe a fourth-grade inquiry unit on soil. The unit was designed and taught by preservice elementary teachers as part of a university science methods course. Using a student-driven inquiry approach to designing curriculum, the unit engaged fourth graders in learning about the physical properties soil, erosion, worms, and plants. Hands-on activities, literacy strategies, and informational texts and websites were used to build student learning.     

Teaching and Assessing Science Process Skills in Physics: THE “BUBBLES” TASK

In the following article, Dr. Seuss's children's books are creatively integrated with science activities through the creation of take-home activity kits. The kits provide families an opportunity to read at home while connecting the enjoyable experience to science content and skill development through associated activities. The kits should be constructed using easy-reading books and aligned to developmentally appropriate academic science standards. Most importantly, they should be designed in a manner so that all family members are participants rather than expecting the adults to teach the expected outcomes. The activity kits can be completed as stand-alone experiences for interested students, used by students who are ready for an additional challenge, or adapted for an entire classroom of students as part of a teacher's normal curriculum.     

Investigating Minerals: Promoting Integrated Inquiry

"Mineral Detectives!" is one of eighteen lessons in the Private Whys? integrated science unit, which uses a guided inquiry investigation to teach students in grades three through five about the role of minerals in our lives. The University of North Texas developed Private Whys? with funding from the Copper Development Association. This lesson can easily be implemented in the classroom, and the entire unit can naturally be integrated into existing elementary school curricula.     

The Monkey and the Hunter

Learning about the water situation in other regions of the world and the devastating effects of floods on drinking water helps students study science while learning about global water quality. This article provides science activities focused on developing cultural awareness and understanding how local water resources are integrally linked to the quality of the world's water supply. After reading and discussing a case study highlighting one water situation facing the people of Kenya, students explore water sanitation and testing methods, including solar pasteurization and the Colilert test for total coliform bacteria and Escherichia coli. These investigations are relevant to inquiry-based water quality labs for high school biology, chemistry, and environmental science.     

Local advisers for the teaching of microbiology in schools

The purpose of this study was to examine the effect of formal teaching of ethical issues related to science on middle school students' attitudes towards science and science achievement. A total of 132 Grade 8 (age 13 – 14years) students in Seoul participated, who were divided into the control and the experimental group. Student attitude toward science was assessed using a questionnaire before and after the intervention which composed of five sub-categories: students' interest level in science, students' perception of the practicality of science knowledge, student's opinion on how science is defined, students' perception of the relationships within science, scientists and society, and students' perception of the value of science. The study further examined whether teaching ethical issues in science had any effect on students' achievement level by means of a pre- and post-test evaluation.

The results of this study showed that teaching ethical issues in science had a positive influence on the students' attitudes toward science, specifically, the interest level in science (p = 0.028) and perception of practicality of science knowledge (p = 0.044). However, there was no statistically significant difference in science achievement level between the control and experimental groups. The results imply that there is a need to explore ethical issues in science education, and that incorporating various materials on the ethical perspectives of science and technology in educational material will promote students' positive attitude towards science.     

A virtual bird’s eye view: Live streaming nest boxes to continue outreach in the era of COVID‐19

COVID‐19 created a host of challenges for science education; in our case, the pandemic halted our in‐person elementary school outreach project on bird biology. This project was designed as a year‐long program to teach fifth‐grade students in Ithaca, New York, USA, about bird ecology and biodiversity using in‐person presentations, games, activities, and outdoor demonstrations. As a central part of this effort, we set up nest boxes on school property and planned to monitor them with students during bird breeding in the spring. Here, we describe our experiences transitioning this program online: we live streamed nest boxes to the students’ virtual classroom and used them as a focal point for virtual lessons on bird breeding and nestling development. In an era of social distancing and isolation, we propose that nest box live streaming and virtual lessons can support communities by providing access to the outdoors and unconventional science learning opportunities for all students. Instituting similar programs at local schools has the potential to increase equitable learning opportunities for students across geographic locations and with varying degrees of physical access to the outdoors and nature.     

Helping Students Reconstruct Conceptions of Thermodynamics: Energy and Heat

Thermodynamics, specifically energy and heat, is a major concept in the foundations of physics and physical science. To determine a strategy to teach thermodynamics meaningfully, the authors conducted classroom action research using interviews to determine secondary physics students' current conceptions of thermodynamics. On the basis of the findings, the authors developed and implemented a science unit to facilitate students' reconstructions of their ideas toward more scientifically appropriate concepts. The lessons, using a learning cycle strategy, and results of the pre- and post-interviews are presented.     

Broadening the voice of science: Promoting scientific communication in the undergraduate classroom

Effective and accurate communication of scientific findings is essential. Unfortunately, scientists are not always well trained in how to best communicate their results with other scientists nor do all appreciate the importance of speaking with the public. Here, we provide an example of how the development of oral communication skills can be integrated with research experiences at the undergraduate level. We describe our experiences developing, running, and evaluating a course for undergraduates that complemented their existing undergraduate research experiences with instruction on the nature of science and intensive training on the development of science communication skills. Students delivered science talks, research monologues, and poster presentations about the ecological and evolutionary research in which they were involved. We evaluated the effectiveness of our approach using the CURE survey and a focus group. As expected, undergraduates reported strong benefits to communication skills and confidence. We provide guidance for college researchers, instructors, and administrators interested in motivating and equipping the next generation of scientists to be excellent science communicators.     

Neuroscientists’ Classroom Visits Positively Impact Student Attitudes

The primary recommendation of the 2010 President’s Council of Advisors on Science and Technology report on K-12 education was to inspire more students so that they are motivated to study science. Scientists’ visits to classrooms are intended to inspire learners and increase their interest in science, but verifications of this impact are largely qualitative. Our primary goal was to evaluate the impact of a longstanding Brain Awareness classroom visit program focused on increasing learners understanding of their own brains. Educational psychologists have established that neuroscience training sessions can improve academic performance and shift attitudes of students from a fixed mindset to a growth mindset. Our secondary goal was to determine whether short interactive Brain Awareness scientist-in-the-classroom sessions could similarly alter learners’ perceptions of their own potential to learn. Teacher and student surveys were administered in 4^th-6^th grade classrooms throughout Minnesota either before or after one-hour Brain Awareness sessions that engaged students in activities related to brain function. Teachers rated the Brain Awareness program as very valuable and said that the visits stimulated students’ interest in the brain and in science. Student surveys probed general attitudes towards science and their knowledge of neuroscience concepts (particularly the ability of the brain to change). Significant favorable improvements were found on 10 of 18 survey statements. Factor analyses of 4805 responses demonstrated that Brain Awareness presentations increased positive attitudes toward science and improved agreement with statements related to growth mindset. Overall effect sizes were small, consistent with the short length of the presentations. Thus, the impact of Brain Awareness presentations was positive and proportional to the efforts expended, demonstrating that short, scientist-in-the-classroom visits can make a positive contribution to primary school students’ attitudes toward science and learning.

Gravity is a pull! Exploring forces and motion with English learners

English learners (ELs) benefit from inquiry-based science instruction that includes explicit attention to language learning goals. The purpose of this article is to share a third-grade unit on forces and motion which integrates science inquiry and writing in science notebooks with the goal of developing ELs' engagement in science, conceptual understanding, and academic language and literacy skills. We demonstrate how to engage diverse students' background knowledge and use classroom activities and discussion to create bridges between everyday and academic language. We utilize excerpts from Peter, Lucia, and Andrea's science notebooks to explore and highlight how teachers can use this resource as a means of communicating science, during instruction. Through these EL students' journals, we discuss the importance of developing language goals at the word, sentence, and discourse level while promoting and supporting ELs' use of the language of science.     

Should the dead sea be sustainable?: Investigating environmental issues using a case study

Many students leave the environmental science classroom with misconceptions centered on the availability of natural resources such as water. This article presents a case study where students assume the roles of various stakeholders and articulate their position on whether or not to pipe water from the Red Sea to the Dead Sea. Additionally, students develop an awareness of local environmental issues.     

Protistological science dissemination

It is rare to meet protistologists who are not passionate about their study subject. The vast majority of people, however, never get the chance to hear about the work of these researchers. Although every researcher working on protists is likely to be aware of this situation, efforts made and tools employed for dissemination of knowledge are rarely documented. Following a proposal by the Italian Society of Protistology, a workshop at the 2019 VIII European Congress of Protistology in Rome, Italy, was dedicated to protistological knowledge dissemination. Through the many interventions, we discovered the diversity of efforts to reveal the protistan world to the general public, including museum exhibitions and activities, public understanding of science events, citizen science projects, specific book publications, the use of protists in teaching at all levels from primary school children to university undergraduate students, and to a global audience via social media. The participation of the workshop delegates in the discussions indicated that presentations on the wonderful world of protists to the public not only increase the visibility and accessibility of protistology research but are also very important for the scientific community. Here we report on some of the key aspects of the presentations given in the dissemination workshop.     

Grass Gazers: Using citizen science as a tool to facilitate practical and online science learning for secondary school students during the COVID‐19 lockdown

The coronavirus disease of 2019 (COVID‐19) pandemic has impacted educational systems worldwide during 2020, including primary and secondary schooling. To enable students of a local secondary school in Brisbane, Queensland, to continue with their practical agricultural science learning and facilitate online learning, a “Grass Gazers” citizen science scoping project was designed and rapidly implemented as a collaboration between the school and a multidisciplinary university research group focused on pollen allergy. Here, we reflect on the process of developing and implementing this project from the perspective of the school and the university. A learning package including modules on pollen identification, tracking grass species, measuring field greenness, using a citizen science data entry platform, forensic palynology, as well as video guides, risk assessment and feedback forms were generated. Junior agriculture science students participated in the learning via online lessons and independent data collection in their own local neighborhood and/or school grounds situated within urban environments. The university research group and school coordinator, operating in their own distributed work environments, had to develop, source, adopt, and/or adapt material rapidly to meet the unique requirements of the project. The experience allowed two‐way knowledge exchange between the secondary and tertiary education sectors. Participating students were introduced to real‐world research and were able to engage in outdoor learning during a time when online, indoor, desk‐based learning dominated their studies. The unique context of restrictions imposed by the social isolation policies, as well as government Public Health and Department of Education directives, allowed the team to respond by adapting teaching and research activity to develop and trial learning modules and citizen science tools. The project provided a focus to motivate and connect teachers, academic staff, and school students during a difficult circumstance. Extension of this citizen project for the purposes of research and secondary school learning has the potential to offer ongoing benefits for grassland ecology data acquisition and student exposure to real‐world science.     

The Mathematical Basis of Mendelian Genetics

In a climate where increasing numbers of students are encouraged to pursue post-secondary education, the level of preparedness students have for college-level coursework is not far from the minds of all educators, especially high school teachers. Specifically within the biological sciences, introductory biology classes often serve as the gatekeeper or a pre-requisite for subsequent coursework in those fields and pre-professional programmes (eg pre-medicine or pre-veterinarian). Thus, how helpful high school science and mathematics experiences are in preparing students for their introductory biology classes is important and relevant for teachers, science educators and policy makers alike. This quantitative study looked at the association between students' high school science and mathematics experiences with introductory college biology performance. Using a nationally representative sample of US students (n?=?2667) enrolled in 33 introductory college biology courses, a multi-level statistical model was developed to analyse the association between high school educational experiences and the final course grade in introductory biology courses. Advanced high school science and mathematics coursework, an emphasis on a deep conceptual understanding of biology concepts and a prior knowledge of concepts addressed in well-structured laboratory investigations are all positively associated with students' achievement in introductory college biology.
