Snippets of information I have compiled that I feel will help me when I start teaching.

Vocabulary Instruction in Science
the five E's of teaching
There is a five step process for teaching in this week's science module that may be of interest to those in other content areas. I will try to present it in a manner that suggests its applicability across the curriculum. It's best summarized as "the five E's."
1. Engage. An activity that creates interest, raises questions, accesses prior knowledge, generates perdictions about what might happen or be true.
2. Explore. An activity that has students working together without direct instruction in order to pursue questions and predictions raised during the Engagement phase. Students puzzle through a problem while the teacher limits herself to asking probing questions as appropriate.
3. Explain. Teacher provides formal explanations and definitions, using students' previous experiences when possible. Students explain concepts in their own words with accuracy the goal.
4. Elaborate. Students apply new knowledge in new situations, asking questions and checking with one another for clarity and understanding. Teacher observes and coaches as necessary.
5. Evaluate. Teacher assesses students' knowledge and use of new concepts and skills. Students assess their own learning and group processing skills.
Note that direct instruction comes at the third stage, not the first. Consider the value of this, with engagement and exploration activities preceding the teacher's formal presentation or modeling of necessary explanations and definitions.

Best Final Exam
Students in an 8th grade science class have been working as partners in the lab all year. At the end of the year, as a final exam, the teacher gives each pair a "mystery substance" to analyze. Students are to hypothesize what it might contain and then do the work necessary to determine what the substance is. They create a data chart and draw conclusions. Each pair then makes a presentation to the rest of the class on the process they used to determine what their mystery substance was. Both must speak, and there must be at least one visual, perhaps a data chart reproduced on the overhead or Smartboard. There is a rubric for A, B, C, and failure. The items in the rubric are the components of the scientific process that students have been learning about and practicing all year. This is a test of the progress they have made in applying that process to solving a scientific "problem".

Using Journals in Science
"Class, I want you to write in your journals today a one paragraph description of how photosynthesis works. Be as clear as you can be. When you are finished, I will ask you to read your description to a partner, who will tell you just how clear your explanation was to him or her."
Creative Assessments
We make a mistake if we allow "creativity" to be some kind of amorphous "thing" that no one can really account for and that therefore cannot really be taught or judged. This is not to say, however, that we can predict what it will be or that we can or should provide a recipe for it. It is to say that we need to teach students how to go about exploring and shaping creative possibilities and then, after careful consideration, move forward. After all, the Muse will usually not come and sit on their shoulder.
Affective objectives and their importance in all content areas
Affective objectives include arguing a position; explaining why one feels more "comfortable" approaching the solving of a math problem one way rather than in other ways; describing one's feelings about a character in a novel; expressing feeling or emotion in a foreign language dialogue; and even comparing one's "gut" feeling about how to proceed with a science experiment with what turns out to be a workable approach.
We can also consider as affective objectives the study of values and feelings as presented in the content to be learned. I can ask students to compare the values of two political regimes or to explain what values most environmentalists have in common. If I then ask students how they feel about these values, whether they endorse them or reject them, whether they have sympathy or dislike, I am asking them to connecting the study of values with the students' own beliefs.
We ignore the affective "domain", which Bloom has made so famous, at our peril!

goals, objectives, and assessment
Physical Science
- Enduring Understanding: Chemical formulas are simplified & standardized descriptions of chemical reactions.
- Enduring Question: What are the basic components of a chemical formula? What do chemical formulas tell you about the chemical reaction?
- Cognitive learning objective: Students should be able to identify reaction types and predict the outcomes of the reaction (synthesis, decomposition, etc).
- Enduring Understanding: Solutions are formed by specific solute-solvent interactions, and depend on energy and other physical conditions.
- Enduring Question: What factors influence the formation of a solution when the solvent and solute are mixed?
- Psychomotor Learning Objective: Students should be able to demonstrate methods of preparing different types of solutions under different situations (concentration, temperature, etc).
Life Science
- Enduring Understanding: Ecosystems are a complex and diverse habitat for a variety of organisms.
- Enduring Question: What relationships exist between living organisms within a given ecosystem? How do organisms interact with their ecosystem?
o Cognitive Learning Objective: Students should be able to analyze the dynamic ways in which organisms in any given ecosystem interact.
- Enduring Understanding: Understand the dynamic nature of ecosystems, and how one small change can have drastic consequences for the entire system.
- Enduring Question: How do ecosystems change over time? What impact can humans have on ecosystems? How can we conserve and protect the environment?
o Affective Learning Objective: Students should analyze the impact humans can have on diverse ecosystems. Students should develop an interest in sustainable/eco-friendly practices, and take an interest in incorporating some of these ideas into their daily lives.
Earth & Space Science
- Enduring Understanding: The environment, and subsequently weather, is influenced by a complex set of physical and chemical processes.
- Enduring Question: What causes the weather? How can we predict the weather?
- Psychomotor Learning Objective: Students should be able to use various instruments to gather data regarding weather (barometric pressure, temperature, etc).
- Enduring Understanding: Oceans are an essential aspect to Earth’s ecology, and provide humans with vital resources for food, fuel, and water.
- Enduring Question: What resources do we get from the ocean? Why is the ocean considered an important part of scientific research?
- Cognitive/affective Learning Objective: Students should be able to describe the effect of Oceans on Earth, and illustrate the variety of ways oceanic resources are utilized. Students should become interested in the importance of Oceans, and take it upon themselves to investigate current research on deep sea vents or other popular oceanic topics.
Assessments
The assessment possibilities for sciences are seemingly endless. I have struggled somewhat with trying to think up ways to assess my students without traditional paper and pencil tests, which I a not a huge fan of. However, as I was reading this chapter and designing my EU’s, EQ’s, and objectives, I found myself with hundreds of possible assessments ideas! That is exciting to me, because it makes me feel more confident in my abilities to truly bring constructivism to my class. One of my favorite assessment types described by Bybee, Powell, & Trowbridge (2008) are creative assessments. The students I observed my first semester of the OATCERT program were required to develop a trail guide about local plant species as part of their botany unit. I thought the idea was great, and the students seemed very engaged and excited about learning botany classifications and identification techniques so they could apply it to their trail walks. I thought, given how boring that topic generally is for most students, that the trail guide assessment was a brilliant idea to get the students engaged. A similar type of creative assessment could be used in the ecology unit described above. For example, I could have the students develop a creative assessment in which they develop a new idea for green/sustainable energy or a new way to manage an ecosystem considered at risk. In this assignment, they will look at the ecosystems around them, try to find creative solutions, and even analyze how they can use more green energy or eco-friendly practices in their daily lives. Both learning objectives from the life sciences section above could be met through this assignment: students will not only have to understand diversity of ecosystems and the dynamic interactions found within them, but they will also have to think about how humans effect their environment. Hopefully this will also help them to generate interest, and apply what they have learned to their own lives. I think an important aspect of this assignment, as Bybee et al. (2008) point out, is to show students previous examples of this type of assignment if available, or give them some ideas to start with ((p. 136).
Another type of assessment that will be frequently used throughout any science class is the practical assessment. According to Bybee et al. (2008), a practical assessment is one that “provides information on students’ skill and problem-solving abilities through the use of apparatus setups, experiments, and open-ended situations that can reveal certain thinking processes” (p. 136). For example, under the physical science section, one of my learning objectives is for students to demonstrate the laboratory skills required to make solutions. Here, I can provide the students with the objective of making different solutions under different conditions. As they progress, I can even add an oral interview into the assessment, and ask them to explain the underlying scientific processes occurring. By having the students explain these processes to me, I will be able to ascertain their true understanding of the subject matter, rather than simply their ability to repeat and set of directions. So often, at least in my experience, lab practicals become more about going through the motions, rather than really learning why something is occurring. I think it would interesting to have the students attempt to create a solution that won’t actually work because the conditions are wrong, and then ask them to explain why. Regardless of how it is done, I think it is much easier than I thought previously to include constructive assessments into my lessons.

Using Backward Design
"I've discovered that giving the final objective and backward engineering the knowledge has been very successful for my students.
It's amazing how this works across all subjects. When I was observing fall semester, I observed an 11th grade English class. The teacher actually gave them the essay question they would have to answer at the end of the unit on the "American Dream" first along with a rubric and the course objectives. He continually revisited the essay question at different times in the course. Most students' views changed by the end of the unit or, at the very least, they were much more in-depth. At the end of this unit, I had the opportunity to read some of their papers. I was very impressed with the quality of their answers. However, if the teacher had just given them this essay question at the end of the unit, I do not believe I would have seen the same caliber of essays. The students were continually thinking about the end question throughout the unit and they had time to develop their ideas."
A wonderful way to teach for depth of thinking and the development of ideas over time!
Note also that the revisiting of the question during the unit is, in fact, formative assessment, which provided students with a greater chance to develop more complex schema (!) about the question prior to the summative assessment at the end of the unit.

Four components of effective teaching, no matter what the content area
1. Construction. Students "construct" meaning idiocyncratically by connecting new learning to current mental schema to create new understandings. For this reason, students need to be active learners rather than passive receivers of what the teacher has already "constructed" through his or her own idiocyncratic learning process. The old transmission model of learning has been discredited by what we now know about the psychology of learning. Although telling students about new learning is important, what students learn from telling is never exactly what the teacher believes she has taught, and sometimes it is very different, indeed. That's the reason why students have to be given learning opportunities in which they develop their own understanding through practice and application and then test it against that of others and the real world.
2. Occupation. To truly understand new learning, students need to "occupy" the discipline. For example, in English students can learn what it's like to "walk in someone else's shoes" when they read literature; in social studies they can project themselves imaginatively into the events and lives of the people of the past; in mathematics, they can choose methods for applying concepts and skills to solving real world problems; in science they can read about scientists and "do science" themselves in a lab or classroom; in foreign language they can play out real world scenarios in the classroom, or, better yet, in conversations with native speakers through Skype, emails, or in person.
3. Negotiation. In order to take charge of their own learning, students need to have some control over its content and the direction it takes. They need to exercise judgment, make decisions, and come to understand their strengths and weaknesses as learners. This requires that they make some choices, to at times be in an executive position. These opportunities can be provided within a framework designed by the teacher. It is not the same as a union negotiating a contract with management. When we "construct" meaning, we "negotiate" it within different social contexts in which we are active participants.
4. Conversation. Conversation among students and the teacher builds understanding as different perspectives are considered and in the process students shape and refine their mental constructs. Q&A is useful, but it is not conversation, nor is it "discussion." Authentic conversation involves students listening to each other and responding in light of what has already been said; it is not a two-channel, teacher-student dialogue in which the student tries to read the teacher's mind. There are some good conversations taking place in the current module. Consider how this can be the norm in your own classroom, even with young people who are not initially very skilled at the give-and-take of sharing ideas.
