Formative Feedback

Formative Feedback:
1- Following the mid-term quiz, questions that have been poorly answered are identified and in the following lecture, the correct solutions are discussed. This helps you to achieve Intended Learning Outcomes 1 to 5.

2- The tutorial format involves groups of about six students working together on field-related questions. These questions, and the students proposed answers, are then discussed together with a group leader in front of the class to provide instant feedback.

Both feedback modes relate to all learning outcomes.

Learning and Teaching Approach

Lectures
(24 hours)

The lectures are a critical vehicle to communicate the key points of a large body of knowledge regarding the physiological and molecular life of plants that has been accumulated throughout the last century.
Acquiring the information presented in the lectures will provide the intellectual framework to particularly apply Intended Learning Outcomes 1, 3 and 5. Learning Outcome 1 is emphasized in Lectures 1-3, Learning Outcome 3 is covered in all lectures and Learning Outcome 5 is the topic of Lectures 4 and 5.

Tutorials
(12 hours)

The tutorials are designed to present genuine scientific problems associated with the lecture content to the students. The problems require you to work in groups to utilize your broader scientific understanding to propose experiments, interpret data and explain results published in the scientific literature. All learning outcomes are addressed in this context, but 2 and 4 are particularly targeted in the tutorials.

Laboratories
(9 hours)

The laboratory sessions involve:
1- Investigation of the evolutionary effects leading to the diversity of plant stem anatomy. This helps you to address Learning Outcomes 1,3 and 5

2- Chromatographic separation of photosynthetic pigments in diverse plant and algal lineages. This is related to Learning Outcomes 1, 3 and 5

3- A field trip to an example of Singapore's highly diverse native forest remnant. This helps you to address Learning Outcomes 1, 3 and 5.

Reading and References

4- Plant Biochemistry, Heldt and Piechulla, 4th edition, 2011, ISBN: 978-0-12-384986-1

Earlier editions are largely equivalent in most cases. (However note that Buchanan 1st edition is out of date regarding plant hormones)

Journal articles as prescribed for tutorials.

Course Policies and Student Responsibilities

1- It is the student's responsibility to be aware of and attend continual assessment exercises and to attend the correct laboratory classes.

2- Although the lectures are recorded, your lecturer will be highly appreciative for every physical attendee.

3- Regarding tutorial classes, please ensure you turn up to your assigned timeslot. Otherwise we may have space problems.

4- Every year there are requests regarding the provision of model answers to tutorial questions and essay questions of earlier exam papers.

Due to the prodigious ability of many students to memorize and reproduce large tracts of text without comprehension of the content, we do not provide model answers to any tutorial or past exam essay questions.

If you have questions regarding any question, please contact the relevant lecturer. We are all more than happy to discuss, read your attempts to solve the problems and provide constructive feedback. We are most impressed if you can present clear evidence that you have attempted to make a real effort towards the solution for example by reading relevant sections in the textbooks.

Please note that due to syllabus changes questions found in previous exam papers may not be relevant. If the material has not been covered, of course it will not be examined.

Academic Integrity

Good academic work depends on honesty and ethical behaviour. The quality of your work as a student relies on adhering to the principles of academic integrity and to the NTU Honour Code, a set of values shared by the whole university community. Truth, Trust and Justice are at the core of NTU’s shared values.

As a student, it is important that you recognize your responsibilities in understanding and applying the principles of academic integrity in all the work you do at NTU. Not knowing what is involved in maintaining academic integrity does not excuse academic dishonesty. You need to actively equip yourself with strategies to avoid all forms of academic dishonesty, including plagiarism, academic fraud, collusion and cheating. If you are uncertain of the definitions of any of these terms, you should go to the Academic Integrity website for more information. Consult your instructor(s) if you need any clarification about the requirements of academic integrity in the course.

Rubric for Laboratories: Written Report (20%)

There are two laboratories, which include a written report (each comprise 10% of the final, total 20%).

a. Short answer questions are scored for factual accuracy (5 marks).

b. Description of the results (plant anatomy drawing and chromatography result, scored out of 5 marks):

4-5 marks
Honest (not idealized) representation of the results is presented (detailed and careful drawings/descriptions). Assignment of features to be described is performed with accuracy and justification.

2-3.5 marks
These reports may appear to show idealized results rather than a true representation of the experiment. Features assigned are generally correct but reasoning may not be explained.

0-1.5 marks
Drawings careless and descriptions may be incorrect. Poor or incorrect reasoning presented regarding the assignment of features.

Rubric for Examination: Essay (36%)

(Each question is scored out of 12 marks, and the total score is scaled to 36%.)

10-12 marks
Question correctly interpreted and engaged. Factually correct and logical arguments are presented. For top marks evidence of comprehension or insight beyond the lecture notes is apparent.

7-9 marks
Question is correctly interpreted and a logical solution is presented. Some incomplete understanding or minor factual errors may be apparent. Level of detail expected for higher scoring answer may be missing.

4-6 marks
Information relevant to the subject area of the question is presented, but may be factually inaccurate. Essays scoring in this range often blindly reproduce memorized lecture slide material.

0-3 marks
Student fails to engage the question. Information presented is not relevant and/or incorrect. No, or insignificant attempt made to answer.
