The mission of the Prairie Science Class is to use the local prairie wetlands ecosystem as an integrating and motivating context to engage 4th and 5th grade students in science, applied math, critical thinking, problem solving, and writing through real world, field-based learning experiences.

If you are being funded by at least a quarter-time research, teaching, or graduate professional assistantship or a Purdue fellowship that is administered as an assistantship, you are required to register for at least 6 credit hours of coursework and/or research in spring/fall semesters (3 credit hours in the summer). Registration should be completed before the end of the first week of classes, or your funding could be in jeopardy.

Located in the Valley Life Sciences Building, this is one of the largest specialty libraries on campus, featuring materials in molecular and cell biology, environmental science, physiology, ecology and nutrition.

Our world is a beautiful, complex, and intricate tapestry of learning all in its own right. Why do we believe that we have the ability or the right to box it in behind brick walls and classroom doors in a place called school?

It takes what we do when we open the doors to the real world and places those same practices in our cycles of teaching and learning. So we can finally remove the brick walls and classroom doors to get at the heart of learning.

Recent research shows that STEAM is a promising approach to positively impacting student achievement and teacher efficacy. In a 2016 study, researchers investigated the impact of STEAM lessons on physical science learning in grades 3 to 5 in high poverty elementary schools in an urban district. Findings indicated that students who received just nine hours of STEAM instruction made improvements in their science achievement (Brouillette, L., & Graham, N. J.).

You can be literate in math, art, reading, social studies, music and science. Literacy is an action with common components that are embedded into how we consume and share information. As such, it is naturally a part of STEAM.

With those understandings in mind, there are many ways to integrate literacy and STEAM intentionally in your classroom. Here are some examples that you may find helpful in your planning for this year.

Special Education students oftentimes go to intervention classes in place of arts classes (technology, art, music, etc). The same also applies to students performing below grade-level in math and reading. This can mean a missed opportunity for engaging these students in a meaningful way.

I have found that one of the most difficult aspects of supervising a STEAM lesson is providing additional wait time, allowing my students to productively struggle, and ignoring my instinct to suggest a given strategy. For instance, remind your students of the tools that they have around the classroom. Encourage them to communicate their ideas or questions to a partner. However, try to avoid jumping in with guided assistance or additional prompting the moment your students begin to struggle. Having a discussion with your class afterwards about the challenges they faced and what they liked about this type of lesson can help them process it as they may be new to this STEAM approach.

During the initial planning stage of a project, many students need to organize their thoughts, arrange their reading notes, and visualize the bigger picture. This is especially true for students who have a difficult time with inferential reasoning. Thinking maps and graphic organizers can help bridge this divide. A flow map (similar to the step by step boxes of a cartoon) can help students recognize or plan out the steps to an experiment or research project. Another time-saving tip is to ask your technology or media teacher (if your school is lucky enough to have one) to align their lessons with an upcoming project in your classroom. The technology teacher at my school trains the students to choose their own graphic organizers on the Vizzle computer program.

Any good STEAM lesson is grounded in inquiry, problem-solving and process-based learning. In fact, this is one of the distinguishing characteristics between Arts Integration and STEAM. So when viewing STEAM in the classroom, you want to pay close attention to the essential question and the process surrounding its exploration.

What problems are being investigated and solved? How are both contents being used to explore the problems? Why is the process important to the question posed? These are all important components to a STEAM classroom or lesson.

This is an approach, not a scripted curriculum. STEAM is meant to encourage curiosity, ask big questions and provoke creativity in the exploration of problem-solving. Everyone can be a part of that in every class.

As with most approaches in education, we need to ensure that our teachers receive high-quality professional development before implementation. There are plenty of options available, including STEAM conferences and courses. Whichever you choose, just be sure that teachers have the ability to learn more about how this approach works and how to use it in their classrooms.

Not all high school classes count as NCAA core courses. Only classes in English, math (Algebra 1 or higher), natural or physical science, social science, foreign language, comparative religion or philosophy may be approved as NCAA core courses. Remedial classes and classes completed through credit-by-exam are not considered NCAA core courses.

Generally, you receive the same number of credits from the NCAA for a core course that you receive from your high school for the class. One academic semester of a class counts for .5 of a core course credit. One academic trimester of a class counts for .34 of a core-course credit. One academic quarter of a class counts for .25 of a core-course credit. A one-year class taken over a longer period of time is considered one core course and is not awarded more than one credit.

The additional core course unit may be taken at a different school than the high school from which you graduated as long as the class is on the new school's list of approved NCAA core courses. If you take the additional core course at a school other than the school from which you graduated, you must provide the NCAA Eligibility Center with an official transcript from the new school showing the additional core-course grade and credit.

The T lymphocyte, especially its capacity for antigen-directed cytotoxicity, has become a central focus for engaging the immune system in the fight against cancer. Basic science discoveries elucidating the molecular and cellular biology of the T cell have led to new strategies in this fight, including checkpoint blockade, adoptive cellular therapy and cancer vaccinology. This area of immunological research has been highly active for the past 50 years and is now enjoying unprecedented bench-to-bedside clinical success. Here, we provide a comprehensive historical and biological perspective regarding the advent and clinical implementation of cancer immunotherapeutics, with an emphasis on the fundamental importance of T lymphocyte regulation. We highlight clinical trials that demonstrate therapeutic efficacy and toxicities associated with each class of drug. Finally, we summarize emerging therapies and emphasize the yet to be elucidated questions and future promise within the field of cancer immunotherapy.

The 1960s represented a period of enlightenment within the field of immunology because two major subtypes of lymphocytes, B lymphocytes and T lymphocytes, were characterized264,265. This was recognized by the 2019 Lasker Award for Basic Science, awarded for the pioneering work by Jacques A. F. P. Miller and Max Dale Cooper that defined the key roles of T cells and B cells in adaptive immunity. B cells recognize circulating antigen in its native form and respond by secreting protective antibodies266. By contrast, T cells recognize peptide antigens, derived from proteins degraded intracellularly, that are loaded onto cell surface MHC molecules, a process called antigen presentation. Two broad classes of T cells that have distinct effector mechanisms are delineated by the expression of either the CD4 or CD8 co-receptor: CD4+ T cells detect antigen in the context of MHC class II molecules and orchestrate the adaptive arm of the immune system by producing cytokines with chemotactic, pro-inflammatory and immunoprotective properties267. At least one CD4+ T cell subclass, CD4+CD25+ regulatory T cells, dampens the immune response following challenge268. CD8+ T cells detect antigen in the context of MHC class I molecules and carry out direct cytotoxic reactions that kill infected or neoplastic cells269.

Before activation, antigen-presenting cells (APCs) load antigen onto MHC molecules to prepare for contact with a T cell that displays a cognate T cell receptor (TCR) while also providing necessary co-stimulatory ligands B7-1 and B7-2. The inhibitory molecule cytotoxic T lymphocyte antigen 4 (CTLA4) is contained within intracellular vesicles in naive T cells, whereas it is constitutively expressed on the cell surface of CD4+CD25+ regulatory T (Treg) cells. Both classes of T cells express the co-stimulatory receptor CD28. Early after activation, generally in the lymphoid tissue, T cells are activated when their TCRs bind to their cognate antigen presented by APCs in conjunction with CD28 binding to B7-1/B7-2. Also, the activated T cells begin the process of displaying CTLA4 on the cell surface. T cells within peripheral tissues upregulate PD1 at the mRNA level early after activation. Late after activation, in lymphoid tissue, CTLA4 expressed by activated T cells binds to the B7-1 and B7-2 molecules on APCs, thereby preventing their binding to CD28 and promoting anergy by decreasing the T cell activation state. At the same time, constitutive expression of CTLA4 on Treg cells leads to trans-endocytosis of B7 ligands and interferes with the CD28 co-stimulatory ability of APCs. Late after activation in peripheral tissues, PD1 is further upregulated transcriptionally, leading to greater surface expression of programmed cell death 1 (PD1), which binds to its ligands PDL1 and PDL2, thereby promoting T cell exhaustion at sites of infection or when confronted with neoplasms.
