About your instructor: I have been at UCSB since 1988 (almost 32 years) and, before that, taught at other institutions for 15 years. I got my PhD at UCLA in 1973. I am looking forward to celebrating my 50th year as a professor in March 2023!b. On coronavirus and COVID-19: We are all experiencing enormous difficulties, as we adjust to social-distancing and other restrictions and worry about our own health and the health of our loved ones. I am working hard to master the new style of instruction, but there will be rough edges at the outset. Meanwhile, I will try to be as flexible as possible to accommodate any special needs.Your photo: Those of you who don't have a photo on GauchoSpace, please consider adding one, to make it easier for us to connect.d. Enrollment: Course enrollment stands at 13 as of today.e. First lecture: Please watch this 81-minute video containing the first lecture.f. The remaining lectures: I will record the remaining lectures as YouTube videos, so there will be no live questioning or discussion. I will accept your questions via e-mail (for quick questions needing a brief answer) or during my office hours (for lengthier ones). This is one of the compromises I have had to make in order to quickly adjust to the new mode of instruction. Links to lecture videos will be provided under Course Calendar.g. Submissions: You will submit solutions to homework assignments and various research reports as PDF attachments to e-mails. Please use a descriptive subject line to let me quickly identify that your e-mail is related to ECE 252B (I will be receiving many e-mails this quarter, given my ECE 1B freshman seminar with an enrollment of 100).h. Office hours: I have 3 general office hours, M 3:00-4:00 and W 3:00-5:00 (HFH 5155). In addition, my regular lecture times for ECE 252B, MW 12:00-1:30, will be devoted to course-specific office hours. So, we are using what is known as the "flipped classroom model": Lectures watched ahead of time, with questions/discussion during the scheduled lecture time.2020/03/13: Welcome to the Web page for the graduate course ECE 252B in spring 2020. As of today, class enrollment stands at 12. Information on the spring 2019 and earlier offerings of the course is available under the "History" section at the end of this page. Throughout the current quarter, this "Course Announcements" section will alert you to significant additions or changes to this Web page. Please visit regularly.

This resource provides a fillable form pdf laboratory procedure and answer sheet for an online mitosis laboratory. It utilizes the a virtual onion root tip activity developed by D.K. Warren at The University of Arizona ( _bio/activities/cell_cycle/cell_cycle.html). It was designed for use as a somatic cell division laboratory exercise in an introductory online biology course.
Week 1: Day 1: : (View the lesson plan for complete instruction in Appendix). Step 1: Have students complete the Heredity Quiz (Pre non-formal) before teaching (to prepare your control data). Step 2: Present pre-survey to the students and have them meet them before the instruction is given. Step 3: After the survey is conducted, discuss Heredity with students. Take note about students thinking of Heredity. (See Appendix for a complete discussion) Step 3: Hand out student worksheets. Students will be working on Worksheet #1(Pre-assessment) while they watch the video clip Step 4: Review the answer to worksheet #1(Pre-assessment) as a class through a discussion of the video clip of the Maury Show. - While the students watch the video. Make sure students are completing the worksheet. Take notes on the engagement of the class towards the lesson. Day 2: Step 1: Vocabulary words: Have students define in their own words the following vocabulary words: Meiosis, sexual reproduction, breeding, inheritance, probability, paternity, maternity, paternal lineage, maternal lineage, DNA, polygenic, phenotype, genotype, gel electrophoresis, humans/ homosapiens, female and male, monogamous, promiscuous (in their own words from prior- knowledge). Through discussion, have students correct each other's definitions and come to a consensus on the purpose of each comment. Step 2: Create groups of 4-5 students (Teacher should make groups according to student's strengths and weaknesses). For example, groups should consist of a strong creative writer, a literate scientific student, a strong reader, an English Language Learner (ELL), or a student with an Individualized Education Program (IEP). This will allow differentiation ad peer scaffolding with teachers' guidance. Step 3: Have students copy down definitions in their notebooks so they can refer to them when needed for homework. The teacher can copy it down on their word walls. Day 3 -5: Have students create a skit of the Maury Show using the vocabulary words formed. Students will assign roles to each other and create a 20-30 line skit to interpret the show's guests. Students will peer review each other's work before the last day of the school week. 2ff7e9595c
