1 COURSE SLO ASSESSMENT REPORT, SCC Department: Biology Course: Biology 214 Plant Diversity and Evolution Year: 2012 Semester: Fall 1) Outcome to be assessed Demonstrate an understanding of the basic theories of biology. 2) Means of assessment and criteria of success A series of questions will be embedded in the lecture exams. 3) Summary of data collected 4) Analysis of data 5) Plan of action/ what to do next Category Question Data Question #1 Question #2 A major evolutionary trend among plants is: a. a reduction in the size of the gametophyte and an increase in size of the sporophyte b. a reduction in the size of the sporophyte and an increase in the size of the gametophyte c. an increase in size of both the sporophyte and the gametophyte d. a decrease in the size of both the sporophyte and the gametophyte E. neither the sporophyte nor the gametophyte have evolved in plants and are basically the same size for all plants. Which of the following statements is NOT true about the alternation of generations life cycle? a. Meiosis produces spores that are haploid. b. Spores develop into the gametophyte generation. c. The gametophyte produces both egg and sperm d. When the sperm fertilizes the egg, a zygote results that develops into the sporophyte. e. The sporophyte generation produces spores by mitosis in structures called sporangia % % Question #1 and #4 had a very high percentage of correct than #2, all of which are of moderate difficulty. The challenging question had a low percentage of correct. These questions all have some sort of comparison that students have to analyze before selecting the answer. Some even require past material to answer the question. Data collection will continue in Fall of 2013.

2 Question #3 Which of the following is NOT an evolutionary trend in the vascular plants? a. Nutritional dependency of the gametophyte on the sporophyte. b. Reduction in size of the gametophyte. c. Reduction in complexity of the gametophyte. d. Increased prominence of antheridia and archegonia e. Decreased reliance on water for transferring sperm to egg % Question #4 Angiosperms are the most successful land plants. This success is due to all of the following except A. animal pollination. B. reduction in size of the gametophytes. C. fruits enclosing seeds. D. highly efficient xylem. E. sperm cells with flagella % Exam # 3 Which of the following statements regarding the structure of DNA is NOT true? a. A DNA molecule naturally exists as two DNA strands twisted together in a double helix b. The two strands of DNA run antiparallel to one another: one 5 3 and the other 3 5 c. The two DNA strands are held together by hydrogen bonds between the nitrogenous bases d. Each DNA nucleotide is joined to another by a peptide bond e. DNA is circular in Prokaryotic cells and linear in Eukaryotic cells %

3 Exam #3 When complementary base pairing occurs between the nucleotides of the two strands of DNA, Thymine will form with its complement, while Cytosine will form with its complement. a. 2 ionic bonds, 3 ionic bonds b. 3 hydrogen bonds, 2 hydrogen bonds c. 2 hydrogen bonds, 3 hydrogen bonds d. 3 covalent bonds, 2 covalent bonds e. 2 covalent bonds, 3 covalent bonds % Exam #3 The structure of the thylakoid membrane is best described as being composed of numerous independent chlorophyll A and chlorophyll B molecules homogenously distributed among cytochrome proteins and ATP synthase protein complexes imbedded in a bilayer of phospholipids shaped into flat disk with a hollow center. a. True b. False % Final Exam The model organism known as Caenorhabditis elegans is useful in the study of development because a. Numerous knockout experiments on this organism has identified the function of many of its genes b. It has revealed how sex is determined in species with 2 sexes c. Its transparent body allows us to watch every cell differentiate from one cell into all of the body cells d. Genes known as egg-polarity genes were first discovered in it e. It serves as a starting point for discovering the genetic controls for the development of all plants %

4 Final Exam Which of the following correctly describes the hierarchy of DNA organization in Eukaryotic cells? a. Double Helix Nucleosomes Chromatin fibers Looped Domains Chromosome b. Double Helix Looped Domains Nucleosomes Chromosome Chromatin fibers c. Nucleosomes Double Helix Chromatin fibers Looped Domains Chromosome d. Nucleosomes Looped Domains Double Helix Chromatin fibers Chromosome e. Chromatin fibers Looped Domains Nucleosomes Chromosome Double Helix %

5 COURSE SLO ASSESSMENT REPORT, SCC Department: _Biology_ Course: 214 Year: _2012 Semester:_Fall 1) Outcome to be assessed 2) Means of assessment and criteria of success 3) Summary of data collected 4) Analysis of data 5) Plan of action/what to do next Demonstrate a coherent understanding of the relationship between plant diversity, form and function, habitat, and life style. 3 multiple choice questions on the lecture exam. 65 expected for C question, 20% correct for B question and 10% correct for A question. 1. Which of the following is NOT an evolutionary trend in the vascular plants? A) Nutritional dependency of the gametophyte on the sporophyte B) Reduction in size of the gametophyte C) Reduction in complexity of the gametophyte D) Increased prominence of antheridia and archegonia E) Decreased reliance on water Afor transferring sperm to egg Fall 12 25/33 (75.8%) 2. Which of the following pairs of structures is least likely to represent homology? A) The wings of a bat and the forelimbs of a human. B) The hemoglobin of a baboon and the hemoglobin of a gorilla. C) The mitochondria of a plant and that of an animal. D) The bark of a tree and the protective covering of a lobster. B E) The brain of a frog and the brain of a cat. Fall 12 18/32 (56.3%) 3. A botanist discovers a new species of plant in a tropical rain forest. After observing its anatomy and life cycle, the following characteristics are noted: flagellated sperm, xylem with tracheids, separate gametophyte and sporophyte generations, and no seeds. This plant is probably most closely related to A) mosses. B) A species from the phylum Charophyceae. C) Ferns. D) C Liverworts. E) Flowering plants. Fall 12 28/33 (84.8%) What I thought was an easy question, a medium-difficulty question, and a hard question; it looks like all three of the questions were about the same difficulty. The middle question is from the final exam while the other 2 are from the second exam. Maybe the higher score on question 2 comes from relearning the material for the comprehensive final. The results from this year are about the same as the results from 2 years ago. Questions 1 and 3 appear to be decent but question 2 may be ambiguous or I am not relaying the material as well as I should. I may go over my lecture notes again and see if I can alter the way I am explaining certain topics.
