Introduction Welcome to the Handbook of Biological Statistics! This online textbook evolved from a set of notes for my Biological Data Analysis class at the University of Delaware. My main goal in that class is to teach biology students how to choose the appropriate statistical test for a particular experiment, then apply that test and interpret the results. I spend relatively little time on the mathematical basis of the tests; for most biologists, statistics is just a useful tool, like a microscope, and knowing the detailed mathematical basis of a statistical test is as unimportant to most biologists as knowing which kinds of glass were used to make a microscope lens. You may navigate through these pages using the "Previous topic" and "Next topic" links at the top of each page, or you may skip from topic to topic using the links on the left sidebar. I have provided a spreadsheet to perform almost every statistical test. I've also linked to a web page for each test wherever possible. Acknowledgment
Inquiry in the Classroom: 7 Simple Tools To Get You Started We know certain characteristics can be encouraged, but not taught, like curiosity. But teachers who use an inquiry based approach can provide techniques that help students learn the questions to ask that may spark a natural interest. Image from Flickr via David Woo Why Use the Inquiry Cycle? Often used by science professionals to work through problems and research, an inquiry-based approach, or inquiry cycle, is also used in classrooms for scientific and non-scientific topics to encourage students during the learning process. The Center for Inspired Teaching says this approach helps create life-long learners by: Teaching students to ask difficult questionsFostering desire and techniques to get knowledgeAllowing students to take ownership of learningEncouraging students to draw connections between academic lessons and their personal lives. Steps of the Inquiry Cycle Technology to Help Students with Inquiry Cycle Step 1: Assessing what is already known. Step 2: Knowing what questions to ask.

More Progressive Ways to Measure Deeper Levels of Learning How do we measure learning beyond knowledge of content? Finding that winning combination of criteria can prove to be a complicated and sometimes difficult process. Schools that are pushing boundaries are learning that it takes time, a lot of conversation, and a willingness to let students participate in that evaluation. “Most schools and most of our learning stops at knowing and we need to move that and broaden it to the doing and the reflecting,” said Bob Lenz, co-founder & chief executive officer of Envision Schools while participating in a Deeper Learning MOOC panel. The charter network’s teachers follow three steps for assessment: know, do, reflect. Skills like critical thinking, problem-solving, and collaboration require practice, Lenz said. “The real power comes in the reflective process, both individually and with peers,” Lenz said. Having a rubric doesn’t mean students aren’t engaged in the assessment process or that there’s no room for surprise or creativity.
Biology Teaching & Learning Resources. Educational articles, drawings, experiments & PowerPoint presentations by D G Mackean Apply for a Teacher Travel Grant This Summer Summer is the perfect time to research and apply for a teacher travel grant. The key is to look in the right places and write a compelling application. Then, once you win an award, you might find yourself kayaking the length of the Mississippi River while developing a river ecology unit. (At least, that’s what one teacher did with a Fund For Teachers grant.) To help you get started, here are some tips for writing winning proposals, a few inspiring articles, and a list of interesting travel grants that you might want to research or apply to this summer. The Best Places to Look Edutopia has covered travel grants in the past. Also, the Institute for International Education is an organization that anyone interested in educational travel should get to know. Grosvenor Teacher Fellowships From National Geographic: Each year, National Geographic and Lindblad Expeditions take K-12 geography teachers on expeditions around the world.

Practical Biology This website is for teachers of biology in schools and colleges. It is a collection of experiments that demonstrate a wide range of biological concepts and processes. Experiments are placed within real-life contexts, and have links to carefully selected further reading. Each experiment also includes information and guidance for technicians. Biology is a practical science. Practical activities are not just motivational and fun: they also enable students to apply and extend their knowledge and understanding of biology in novel investigative situations, which can aid learning and memory, and stimulate interest. We have published a new set of resources to support the teaching of practical science for Key Stages 3-5. Unfortunately, we are unable to respond to questions from teachers, technicians or students on how to use the experiments on this website.
