Workshop Summary: Beyond Labz is a set of sophisticated and realistic virtual laboratories that have been used by millions of students over the past 20 years. Subjects covered by the virtual labs include general chemistry, organic chemistry, physics, physical science, and biology. We have recently updated the virtual labs so they are browser-based with a number of new features including tracking student lab books and the student journey through the lab. With over 20 years of experience and feedback from students and teachers worldwide, we have learned much about how to enhance and augment classroom and laboratory instruction using the virtual labs. In this presentation we will provide a brief update on the new features in Beyond Labz, and we will provide onboarding instructions and describe how to use the virtual laboratories in various curriculum settings and use cases, and we will show the labs can be used to enhance inquiry-based instruction. We will also describe some of the recent research we have performed using these and other simulation products we have created.

TAKEAWAYS:
Beyond Labz simplifies and reduces the cost and expertise needed to provide crucial laboratory experiences and practice for Secondary and Higher Ed students. Attendees will learn how the labs are used for pre and post lab experiences, credit recovery and lab make-up, student engagement in class, and meeting NGSS standards. Basic onboarding and startup instructions will be provided for drop-in solutions, and instructions for using some of the more sophisticated features will also be described.

Everyday events make us wonder. Some events are easily explained, while others cannot. When these events are examined and tested through virtual simulations, they give students an opportunity to think. Why do some objects float and others sink? What is the difference between a solar eclipse and a lunar eclipse and how often does that happen? Learn how to use virtual simulations to help students dig deeper and get inspired by science and STEM phenomenon! Through this highly interactive session, educators will be able to understand the added value of including simulations to their current lab practices. Although hands-on activities are always important, simulations allow for a deeper understanding of content for all students. When coupled with hands-on learning, students can create more moments to explore, discover and apply new concepts. Simulations are repeatable (to allow for trial and error) so students can practice skills again and again to make STEM concepts stick!

TAKEAWAYS:
Use of virtual simulations builds a deeper understanding of concepts.

The structure and function of nucleic acids is a foundational concept of biology. Although most students recognize the double-helical structure of DNA, they have difficulty understanding the importance of the details. During this hands-on, minds-on workshop, participants will examine how modeling with this approach deepens student engagement and inquiry. While investigating our first model, participants explore how using a simple but carefully designed model allows students of all levels to discover basic features of DNA structure and function, and to formulate questions about it. Next, workshop participants will explore DNA’s dynamic structure and function using an atomically accurate model of DNA. With this model, we will assemble five nucleotides, buid DNA and RNA polymers, and examine the features, including the flexibility, of both molecules. Both models will be used to demonstrate the function of DNA, including transcription and translation. (NGSS Science and Engineering Practices / Developing and Using Models) to explore the structure of DNA, this workshop will challenge teachers to go beyond the traditional approach of just teaching the facts of DNA structure. By using well developed models, students can engage with these foundational concepts through discovery and inquiry. We will demonstrate an NGSS-aligned teaching practice in which students are encouraged to ask questions and develop critical thinking skills. Teachers will also learn how these instructional materials can be utilized to design formative and summative assessments for their students.

TAKEAWAYS:
Consider how a model-based approach to investigating DNA deepens student understanding and inquiry.

Research has shown better ways to incorporate learning theory in our assessment practices. This session links constructivist learning theory to instructional practices and meaningful formative assessment. Teachers often seek more clarity on the term "inquiry" related to science instruction and the new role of the teachers in students' learning. When we empower students to have agency, how do we still provide support and coaching? We will discuss current findings from Hattie, William, and other educational researchers on how to involve students in the learning process. New tools and software designed around inquiry can make teaching science and STEM exciting. Anchored by essential questions, we will demonstrate tools for student learning which organize and visualize the data while allowing students time to focus on analyzing and understanding instead of simple creation. While not a replacement for hands-on activities, we will examine ways to use simulations to enhance learning. Discover ways to strengthen sense-making and enable your students to think like scientists while exploring immersive 3D worlds where students make observations and collect evidence for CER assessments. We will also discuss assessment through the lens of UDL (Universal Design for Learning) and social/emotional standards.

Participants will assess their biggest challenge areas with respect to student misconceptions about chromosome structure and function, including mitosis. Traditional wet labs like planaria, fruit fly genetics, and C-fern growth will be used to contextualize the hands-on models’ utility throughout the school year. Next, foam puzzle chromosomes will be introduced and used to model a round of DNA replication in the cell cycle, resulting in 4 chromosomes. The processes of mitosis and meiosis will be modeled and compared, to invite inquiry about why the processes are different. Whole chromosomes will be related with molecular chromosome details to illustrate how DNA is wound into a chromosome structure. Nucleosome models will further highlight the wrapping of DNA around histone proteins to compact the genome for replication. Participants will be asked to share how they teach about genetic variation in their classes. Following a discussion of their challenges, we will model variation first using the puzzle chromosomes to generate “crossing over” events and next by using the molecular-detailed expanded chromosomes. Finally, inheritance of Hemoglobin will be highlighted and modeled and Punnett squares models will be enhanced through using the foam models.
