Important Dates: Seminar Class will meet March 11, March 12 and March 13 and on May 11 and May 12.

SCED 398-A Box 3-Criteria for evaluating Candidate Artifacts of Standard 1-Content. Respond to the criteria in narrative form and attach the narrative to your artifact.

a. Describe the science principles and concepts represented by the work. When describing the science principle, identify the major theory, law or understanding that guides the work (e.g., evolution, earth formation, atomic structure, weather, plant/animal adaptation). Simply stating one word isn't enough. Describe why and how the work fits into this overriding theme.

b. Describe the sub-content that was reinforced or taught by the science experience. For example, if the principle was connected to plate tectonics, describe the focus content ideas.

c. Why this artifact represents your content readiness-what was special about it, why did you choose it for your portfolio?

d. Why this artifact is most useful in your science teacher preparation.

 

SCED 398-B: Consider carefully the artifacts you are submitting to represent your understanding of "Unifying Science Disciplines". Defend each submission in narrative form by addressing a and b below.

a. Describe how the artifact is a  "unified science principle" and why or how this artifact represents your understanding of "unifying science disciplines".

d. Why this artifact is most useful in your science teacher preparation.

 

Some Absolute Musts for the First Few Days of Student Teaching:

Learn the names of the students: a class picture and/or use of a seating chart will help. .

Learn how the teacher runs the classroom. What procedures are in place? How are labs, lecture and everything else conducted? Observe carefully and then ask questions about what you observed.

Set up a conference time-maybe just a few minutes, when you and the teacher can plan together, discuss you progress. Keep the communications going.

Keep a notebook of ideas suggested by the teacher. Do everything professionally.

Most student teacher take over the class slowly. You will probably observe the first 2-3 days and then move into teaching. You may teach the entire teacher’s day if appropriate. There is some flexibility here depending on the situation.

NSTA Position Statement


 

 

Responsible Use of Live Animals and Dissection in the Science Classroom

Introduction

NSTA supports the decision of science teachers and their school or school district to integrate live animals and dissection in the K-12 classroom. Student interaction with organisms is one of the most effective methods of achieving many of the goals outlined in the National Science Education Standards (NSES). To this end, NSTA encourages educators and school officials to make informed decisions about the integration of animals in the science curriculum. NSTA opposes regulations or legislation that would eliminate an educator's decision-making role regarding dissection or would deny students the opportunity to learn through actual animal dissection.

NSTA encourages districts to ensure that animals are properly cared for and treated humanely, responsibly, and ethically. Ultimately, decisions to incorporate organisms in the classroom should balance the ethical and responsible care of animals with their educational value.

While this position statement is primarily focused on vertebrate animals, NSTA recognizes the importance of following similar ethical practices for all living organisms.

Including Live Animals in the Classroom

NSTA supports including live animals as part of instruction in the K-12 science classroom because observing and working with animals firsthand can spark students' interest in science as well as a general respect for life while reinforcing key concepts as outlined in the NSES.

NSTA recommends that teachers

  • Educate themselves about the safe and responsible use of animals in the classroom. Teachers should seek information from reputable sources and familiarize themselves with laws and regulations in their state.
  • Become knowledgeable about the acquisition and care of animals appropriate to the species under study so that both students and the animals stay safe and healthy during all activities. 
  • Follow local, state, and national laws, policies, and regulations when live organisms, particularly native species, are included in the classroom.
  • Integrate live animals into the science program based on sound curriculum and pedagogical decisions.
  • Develop activities that promote observation and comparison skills that instill in students an appreciation for the value of life and the importance of caring for animals responsibly. 
  • Instruct students on safety precautions for handling live organisms and establish a plan for addressing such issues as allergies and fear of animals.
  • Develop and implement a plan for future care or disposition of animals at the conclusion of the study as well as during school breaks and summer vacations. 
  • Espouse the importance of not conducting experimental procedures on animals if such procedures are likely to cause pain, induce nutritional deficiencies, or expose animals to parasites, hazardous/toxic chemicals, or radiation. 
  • Shelter animals when the classroom is being cleaned with chemical cleaners, sprayed with pesticides, and during other times when potentially harmful chemicals are being used.
  • Refrain from releasing animals into a non-indigenous environment.

Dissection

NSTA supports each teacher's decision to use animal dissection activities that help students

  1. develop skills of observation and comparison, 
  2. discover the shared and unique structures and processes of specific organisms, and
  3. develop a greater appreciation for the complexity of life.

It is essential that teachers establish specific and clear learning goals that enable them to appropriately plan and supervise the activities. Teachers, especially those at the primary level, should be especially cognizant of students' ages and maturity levels when deciding whether to use animal dissection.

NSTA encourages teachers to be sensitive to students' views regarding dissection, and to be aware of students' beliefs and their right to make an informed decision about their participation. Should a teacher feel that an alternative to dissection would be a better option for a student or group of students, it is important that the teacher select a meaningful alternative. 

Finally, NSTA calls for more research to determine the effectiveness of animal dissection activities and alternatives and the extent to which these activities should be integrated into the science curriculum.

Regarding the use of dissection activities in school classrooms, NSTA recommends that science teachers

  • Conduct laboratory and dissection activities with consideration and appreciation for the organism.
  • Plan laboratory and dissection activities that are appropriate to the maturity level of the students.
  • Use prepared specimens purchased from a reputable and reliable scientific supply company.  An acceptable alternative source for fresh specimens (i.e., squid, chicken wings) would be an FDA-inspected facility such as a butcher shop, fish market, or supermarket. The use of salvaged specimens does not reflect safe practice.
  • Conduct laboratory and dissection activities in a clean and organized work space with care and laboratory precision.
  • Conduct dissections in an appropriate physical environment with the proper ventilation, lighting, furniture, and equipment, including hot water and soap for cleanup.
  • Use personal safety protective equipment, such as gloves, chemical splash goggles, and aprons, all of which should be available and used by students, teachers, and visitors to the classroom.
  • Address such issues as allergies and squeamishness about dealing with animal specimens.
  • Ensure that the specimens are handled and disposed of properly.
  • Ensure that sharp instruments, such as scissors, scalpels, and other tools, are used   safely and appropriately.
  • Base laboratory and dissection activities on carefully planned curriculum objectives.
  • Be prepared to present an alternative to dissection to students whose views or beliefs make this activity uncomfortable and difficult for them.
