Biology, grade 9: Cellular reproduction
Texas: BIOLOGY TEKS
5) (A) describe the stages of the cell cycle, including deoxyribonucleic acid (DNA) replication and mitosis, and the importance of the cell cycle to the growth of organisms;
(6) (G) recognize the significance of meiosis to sexual reproduction;
The topic the students will be exploring is cell division. This covers the workings of the cell cycle, mitosis, and meiosis. Students are responsible for knowing the stages involved in each process, the results of each process, and the overall purpose of each process in organisms. In addition, they must also be able to discuss condition that can arise if the processes do not proceed correctly. Students are expected to know and be able to use correct terminology and be able to identify and describe the details of what occurs during each stage. Modeling is a large part of being able to understand the inner working of the processes involved in cell division. As a result, a class generated wikis will be used to build class notes and resources for student learning. Blogs will be used for group discussions. Software and media will be used to create 2D pictures and power points and record 3D modeling of the processes. Below is a more detailed list of the technology integration.
1.Internet use: search of on-line databases, educational websites, and videos to uses for research and for resources to post on wiki.
2.Class created Genetics Wiki: student groups will work together to help create class generated glossaries, notes, videos and pictures covering the topics of the cell cycle, mitosis, and meiosis, including but not limited to drawing and description of stages, video demonstrations, and importance of each type of cell division. In addition, students will create a list and description of different conditions that occur as a result of mistakes in the cell cycle, mitosis, or meiosis. Students will be assessed using a rubric with categories such as correctness of information, frequency of group and group member contribution, and clarity and detail in explanations and activities.
3.PowerPoint or Google Docs presentation: Students will create a presentation comparing and contrasting the cycle, mitosis and meiosis, including the cell types each occurs in addition to number of cells involved and produced, chromosome numbers, and genetic composition of the resulting daughter cells.
4.Blog: A class cell division blog will be used to provide guided questions for students to respond to. Students will post their answers to questions and provides comments on group member’s postings.
5.Ipod: Students will record group generated model demonstrations of stages of mitosis and meiosis to post on class created genetics wiki. They would use manipulative such as beads, pipe cleaners, string, or other household items to show the cell division processes. Student peers would then comment on the effectiveness of the model for demonstrating understanding and provide feedback for improvement before final grading, submission/ posting for assessment.
6.Concept mapping software: students will create dichotomous keys/ flow charts explaining how they would determine which specific process and stage a cell they were investigating was in (cell cycle, mitosis, or meiosis). These will be posted on wikis as class notes and resources.
7. Google Docs (create form): students groups will create and post practice quizzes on blogs for peer groups to take. Students will vote on best quiz to post on wiki for class use and practice.
Great job. Biology is a great subject to teach using technology. Visual images realy enhance learning (a picture or video is worth a thousand words). When students can actually see how things come together, it is like a light pops on.
ReplyDeletePowerPoint or Google Docs presentation: This is a great way to use the technology. I didn't think about using the power point or the goggle docs. I guess I now have an idea on how to improve my activity. I need to revise and change things on my lesson. Did you have problems integrating the web 2.0 tools to the lesson? The cellar reproduction lesson is a hard topic but it is lots of fun. I am teaching 3rd graders and I really want the opportunity to teach at the high school because there are so much technology that can be integrated into the lesson.
ReplyDeleteThe task of students creating 2D or 3D visuals is an excellent idea. Much, if not all, of the technology used in science today invovles the use of 3D models. Your students have the opportunity to use technology connected to real world use. Thanks!
ReplyDeleteIt makes a lot of sense to integrate technology into the lesson since many students are very comfortable with it. I think this understanding of technology and having assignments and projects that offer opportunities to implement technology creates a favorable learning environment.

ReplyDeleteI like how you used seven different technological methods in your lesson. How will you assess their work? You may think of building a rubric for each technology, because each one has specific nuances that you will want to capture and grade accordingly.
