Instructor Mark Krotec
Instructor Biography: Mark Krotec has been teaching Biology and Chemistry at Pittsburgh Central Catholic since 1981. His primary work involves the instruction of Honors Biology, Honors Biology II, Environmental Science, and AP Biology students. In addition, he has served as the director of extracurricular science (Pennsylvania Junior Academy of Science, Science Bowl, Carnegie Science Fair, and the Envirothon) for over a decade. Outside of his school, Mark has been actively involved in the promotion of teacher education and curricular development. He has served as president and executive board member of the Western PA Biology Teachers Association, in addition to serving as a frequent workshop presenter at local, statewide, and national conventions, including the NSTA, NABT, and College Board. Mark has also created a Diocesan Teacher Scholarship program, resulting in the full funding of over 50 teachers to NSTA conventions. In addition, Mark has developed a Diocesan in-service program, directing yearly workshops with these funded teachers.
Mark has served as a consultant for the College Board for over 15 years, directing various workshops and summer institutes. He has continued to focus much of his efforts on promoting science process, especially inquiry science, within the AP curriculum.
Mark continues to update his science knowledge and skills through research internships at local universities, further inspiring him to translate those experiences into secondary science curricular supplements. He has been awarded research fellowships from the American Society for Clinical Investigation (ASCI), the American Society for Cell Biology (ASCB), the American Society for Biochemistry and Molecular Biology (ASBMB), and the Professional Enhancement Program (PEP). In addition, he has participated in numerous educator enrichment programs such as the Pennsylvania Commonwealth Biology Initiative and Howard Hughes Science Teacher Workshops. From June of 2000 to August of 2001, Mark immersed himself in the revolutionary field of tissue engineering, performing sabbatical research and educational outreach for the Pittsburgh Tissue Engineering Initiative (PTEI). With the development of the first tissue engineering educational outreach manual, he continues to serve as a liaison between the biomedical research community and science educators. Within the past decade, Mark has presented to classes in over 30 schools, in addition to directing over 40 tissue engineering workshops for science educators, as well as leading Middle School and High School Tissue Engineering summer camps. He continues to serve as a “master” teacher for the PTEI, performing educational outreach and contributing to the further development of outreach manual. Mark also continues to serve as an outreach coordinator for Carnegie Mellon-based laboratory exercises, three of which he personally developed. Over fifteen other curricular supplements have been shared locally and nationally, including the activity manuals Beyond Bead Biology and An Education Outreach Manual in Tissue Engineering.
For these contributions to science education, Mark has been honored with a variety of awards including: Outstanding Biology Teacher of PA, NSTA Distinguished Teaching Award, NABT Molecular Biology Teaching Award, Presidential Teaching Award (PAEMST), Radio Shack National Teaching Award Recognition, Diocesan Golden Apple Award, Carnegie Award for Excellence, and the Pittsburgh Spectroscopy Society Teaching Award.
Outside of academics, Mark continues to serve as a table tennis coach for the school. In addition, he serves as the president of a USATT-affiliated table tennis club.
AP Biology Course Description
This workshop is designed to enhance teacher effectiveness in the new AP Biology curriculum. The goals are to equip instructors with a firm understanding of the new Curriculum Framework, provide direct experience with the new inquiry lab activities, familiarize teachers with the revised national exam, and to offer suggestions regarding effective implementation of the new curriculum within the constraints of a high school system. To accomplish these goals, instructors will be provided with numerous pre-AP and AP teaching strategies and proven activities, enabling them to more effectively modify life science education in support of inquiry-driven instruction. In addition, the workshop will strongly promote the creation of an instructional community, greatly expanding the available resources for both AP and pre-AP teachers.

Teaching Evolution through Human Examples (TEtHE) Project
AP Summer Institute: Biology (Montgomery College, Maryland)
Teaching Evolution through Human Examples (TEtHE), NSF DRK-12 funded project led by Dr. Briana Pobiner of the Smithsonian’s Human Origins program, is developing and investigating the effectiveness of: 1) data-driven, real world examples of human evolution to teach basic evolutionary concepts in AP Biology classes, and 2) culturally/religiously sensitive (CRS) teaching strategies to address potential classroom conflicts and challenges related to teaching evolution. Each supplement is designed to provide 1-2 weeks of instruction of concepts in the AP curriculum, and teachers can choose how many to use.
The curriculum supplements are designed to help you meet many of the learning objectives in AP Biology in the Big Idea of evolution, using human examples. This has proven to be an effective approach in informal education settings like museums; we are testing its effectiveness in the classroom. Each supplement is a cohesive series of lessons intended to be taught together that provide opportunities for students to engage with a range of experiences, data, activities, and concepts that contribute to a deep understanding of content; some include laboratory investigations. These supplements, designed to provide 1-2 weeks of instruction of concepts in the AP curriculum, are not a replacement for all the content you might include related to evolution, but rather, they include specific lessons, resources, and activities that you can use to deliver instruction that addresses the curriculum. The curriculum supplement topics are:
- Human Adaptation to Altitude
- Malaria (emphasizing parasite and human evolution examples outside of sickle cell anemia),
- The Evolution of Human Skin Color
- What Does It Mean To Be Human? / An Introduction to Understanding Evolutionary Relationships
CRS Teaching Strategies are designed to help address potential conflicts or discomfort that might arise in teaching evolution with human examples. They comprise 1) background information and perspectives about a selection of topics including the nature of science as pertinent to managing any conflicts between science and religion; a range of creationist views; a variety of possible relationships between science and religion; and a review of legal cases dealing with the teaching of evolution; 2) two options for classroom activities: a directed discussion and a historical role play; and 3) key phrases or language for managing classroom discussions.
Information and Instruction
You will be provided with electronic copies of all of the materials before the APSI. Dr. Briana Pobiner and Dr. Connie Bertka (author of the Teaching Strategies) will give a basic outline of materials during a short session on June 30th. Dr. Bertka will be available on July 2nd for a Q&A session on the Teaching Strategies, and the project curriculum developer Dr. Paul Beardsley will be available for a Q&A session on July 3rd. If you choose to implement these materials in your classroom in 2014-2015, Dr. Pobiner will send you the final versions, ask you to have your students fill out related attitudinal and content knowledge assessments, and support you via email and phone during implementation.
