Hello UBC EDUC 272 students!
My name is Chris Campbell, your instructor for EDUC 272. I am looking forward to working with you over the next four months on this course and hope 2016 is a good year for you!
I am very excited that I will have a chance to work with all of you in online and then in Dadaab!
…………….
We will do EDUC 272 in two parts:
1) Online from now until March 24.
2) Face to face in Dadaab from April 2.
During the course, we will use two main ways of communicating:
1) EDUC 272 BLOG
This blog will be used to provide you will all the documents for the course. You will also post your assignments and discuss topics there.
In the next two or three days, could you please:
a) Please become familiar with the course blog. Get on a computer with Internet and go to our blog: https://blogs.ubc.ca/dadaab/educ-272/. You will see that the format is much like Winston, who is one of my colleagues at UBC.
b) Read the full course outline. You can find it on the blog. I have also attached this course outline to this email.
c) Read Sections I, II, III of the document “January Task” This document gives an overview of your tasks from January to March. From January to March you will select a lab (from Labs 1-20 on the blog) to do with your students at your school. Your March assignment is to send me a video recording of you and your students doing the lab on WhatsApp. Please start working on the January Task as soon as possible so that you will have enough time to do everything.
d) Start working on the January Task. This is a big assignment!!! You will need to look at Handout 1.1 – Primer on labs and also at Labs 1-20. Please post your task on the blog by January 24. It is very important that you keep up with the work!
2) WHATSAPP GROUP
Our Whatsapp account is EDUC 272 Dadaab. This WhatsApp group is for shorter communications about the course and to upload your video of you and your students doing the lab in March before I come to Dadaab. Please remember that the WhatsApp group discussion is only for topics related to the course – it is a friendly but academic group focused on EDCU 272. It is not really for discussing other topics that are not related to EDUC 272.
Khalif Kobane and I have set this group up at telephone number 112506612242. Khalif is going to assist us if there are any problems.
In the next two or three days, can you please:
a) Sign up to the WhatsApp group.
b) Play my 1-minute self-introduction.
c) Introduce yourself in about 1 minute. You can record yourself speaking – as a video or as an audio file. I am interested in knowing a few things about you, your interests, and your teaching and students!
I hope you will work hard on this course because I think it could really help improve your teaching skills. I am looking forward to hearing from you and am ready to answer any questions any time about the course – please feel free to contact me with questions!
Thanks very much and good luck on this course!
Chris Campbell
Hi EDUC 272!
Below I give an example of how to answer the questions in Section III of the January Task. I wrote answers only for Question 1, 2, and 3. Please do all of them and keep the answers short!
……………
January Task – Answers
READING: Handout 1.1 – Primer on labs
Question 1
What is your name?
Chris Campbell
Question 2
How many chemistry laboratory experiments or demonstrations have you done as a teacher?
I have done 45 labs as a teacher.
Question 3 (0.5 marks)
What was the most meaningful chemistry laboratory or demonstration that you did as a teacher? Why?
I like an endothermic reaction demonstration: Barium hydroxide Ba(OH)2-8H20 mixed with ammonium thicyanate NH4SCN. I did it when I was learning how to teach chemistry.
It’s simple but shows students how reactions can absorb heat. I it in a beaker on top of a piece of wet wood. Because the reaction is endothermic, it freezes the beaker to the wood! It is really memorable for students.
What was the most challenging chemistry laboratory or demonstration that you did as a teacher? Why?
The reaction above. It was challenging (it was dangerous) because I asked a student to try to separate the beaker that was frozen on the wood. She pulled the beaker hard and the reaction products went into her eyes. That was dangerous, but we washed her eyes out with lots of water and she was OK. I was only a student teacher then, but it taught me the importance of safety. Now I always ask students to put safety glasses on

( i am sending the answers only because iam using a smart phone which cannot accomodate all since i have no acess to computer)
Q1. my name is ibrahim mohamed warsame
Q2. I have done 20 chemistry labs as a teacher. some of the labs include volumetric analysis, acid and base reaction, heating carbonates, exothermic reaction,endothermic reaction, test of cations and anions,test of gases e.t.c
Q3. (a)the most meaningful chemistry lab that i did was the volumetric analysis because its normally common in the kenya national examination(k.c.s.e).
Q3 (b). The most challenging demonstration that i did as a teacher was the acid base reation because acids are flammable and can burn you. also acids are corrosive if it touches your body.
Q4.1. according to my perspective using text to study the scientific investigation in the laboratory is the best because the text is an important source of information to supplement the scientific investigation that centres around the laboratory. the text also contains questions to test the learners level of understanding . the text also provides background information needed to suggest investigation.
Q4.2 the three phases are very important when carrying out practical work in such away that pre lab session helps students to prepare the work to be done in the laboratory. laboratory work contains procedures and hints for guidance on how to do the practical and also to save time. post lab contains questions to be answered by students from their observation and this gives the learners extra skills and experience.
Q5. i would have try oral presentation because it enables the teacher to know each students level of understanding. oral presentation also impart learners with confidence and courage
Q6. The following are the equipment in our school
-test tube and rack
-beaker
-boiling tube

Question 4
Read pages 1 and 2 until the heading Laboratory Reports (Handout 1.1 – Primer on labs) and answer the questions that follow. These pages are from a laboratory text called Heath Chemistry.
Question 4.1 (1 mark)
On page 1, in paragraph 3 this writer says: “Rather than using laboratory work to supplement study in the text, the text is used as an important source of information to supplement the scientific investigation that centers around the laboratory.”
Consider these two approaches to teaching and learning chemistry: (i) Using lab work to study the text; (ii) Using the text to study scientific investigation in labs. Which teaching approach do you think is best? Which approach are you familiar with in your own learning and teaching of chemistry? Explain in 4-5 sentences.
Using the text to study scientific investigations in the labs
I am really familiar with the approach of using the text to study the scientific investigation the laboratories;
This approach supplements scientific investigations that centers arround the laboratory
The text help the teacher to organise laboratory or practical lesson for the students
The text also provide important information needed to suggest lab investigations and to interpret observations during experiments
Question 4.2 (1 mark)
Page 1 recommends carrying out experiments in three phases: pre-lab session, laboratory work, and post-lab session. In 4-5 sentences, summarize why they recommend this.
These three phases are recommended because it breaks the bulk and reduces time to do the task as well as giving the students a good understanding of what they are expected.
For example; prelab work prepares the student for the work to be done in the laborarator and points out reasons for doing the experiments as well as the problems being investigated.
Laboratory work helps the teacher to give assignments, its procedural hints and suggestions.
Post lab makes the students correlate, and evaluate the data they obtained related to the question required to solve.
Question 5 (1 mark)
Read the Laboratory Reports section on pages 1 and 2 of Handout 1.1 – Primer on labs. These ideas for getting students to report laboratory results without doing a traditional lab report. Choose one idea that you would like to try and write it below. Then state in 1-2 sentences why you would like to try it.
Use of transparencies
I would like to try this because use of transparencies saves time as students are issued with acetate sheet and pens to prepare tables of the data prior to the actual class.
Then during presentation the tables made can be shown using overhead projector.
Question 6 (1 mark)
Look at the Common Laboratory Equipment in page 4 of Handout 1.1 – Primer on labs. If you have any of the equipment in the picture at your school or you can find, make, or adapt something to fit the same purpose, list it below.

Question 4
Which of these four labs do you want to try in your class? Write the name of the lab below.
Acid base titration
ABDI MSULWA
UNIVERSITY OF BRITISH COLUMBIA
STUDENT’S ADMISSION NO. 92957142
CHEMISTRY ONLINE ASSINGMENT
January 24, 2016 TASK
READING: HANDOUT 1.1 – PRIMER ON LABS
QUESTION 1.
What is your name?
My name is SALAT ABDI MSULWA.
QUESTION 2.
How many chemistry laboratory experiments or demonstrations have you done as a teacher?
I have done 19 lab demonstrations as a teacher.
QUESTION 3.1 What was the most meaningful chemistry laboratory or demonstration that you did as a teacher? Why?
The most meaningful laboratory demonstration that I did as a teacher was acid base titration with form three students. This was because it gave me the accurate results that I was expecting I together with my learners.
QUESTION 3.2
What was the most challenging chemistry laboratory or demonstration that you did as a teacher? Why?
The most challenging chemistry laboratory or demonstration that I did as a teacher was the above one. This is because I asked one of my learners to suck one of the reagents using a pipette and eventually he ended up putting it into his mouth. Quickly, I advised him to rinse his mouth immediately with a lot of water and fortunately it didn’t harm him. This laboratory demonstration was also time consuming and it took me a lot of time to prepare it that is why it was challenging.
Question 4.1 (1 mark)On page 1, in paragraph 3 this writer says: “Rather than using laboratory work to supplement study in the text, the text is used as an important source of information to supplement the scientific investigation that centers around the laboratory.”
Consider these two approaches to teaching and learning chemistry: (i) Using lab work to study the text; (ii) Using the text to study scientific investigation in labs. Which teaching approach do you think is best? Which approach are you familiar with in your own learning and teaching of chemistry? Explain in 4-5 sentences.
Despite the fact that the two approaches are both useful to the teaching and learning chemistry but the choice (ii) Using the text to study scientific investigations in labs, is the best according to the Dadaab setting. This is the approach which I am even familiar with it in my own teaching and learning of chemistry. This is because in Dadaab secondary schools due to lack or inadequate of laboratory resources and at times lack of experienced chemistry teachers. Therefore, the text book plays a major role in investigating scientific studies in the labs.
Question 4.2 (1 mark)Page 1 recommends carrying out experiments in three phases: pre-lab session, laboratory work, and post-lab session. In 4-5 sentences, summarize why they recommend this.
The reasons as to why it is recommended to carry out experiments in three phrases; pre-lab session, laboratory work, and post lab session is that: In the pre-lab session, students are acquainted with the basic/background information such as the problem being investigated, reasons for investigating it, what is expected from the experiment, safe precautions to be observed and the procedure to follow in the experiment. In the laboratory work, this is where the students apply the theoretical knowledge gathered in the pre-lab session into actual experiment or practical in order to obtain successful learning experiences. While in the post lab session, students correlate, interpret, and evaluate the data obtained in the practical and draw their own conclusions based on the experimental evidences and also formulate new questions based on their results and suggest further experiments that might attempt to answer the questions.
Question 5 (1 mark)Read the Laboratory Reports section on pages 1 and 2 of Handout 1.1 – Primer on labs. These ideas for getting students to report laboratory results without doing a traditional lab report. Choose one idea that you would like to try and write it below. Then state in 1-2 sentences why you would like to try it.
The idea that I would like to choose and try is the idea of group reports: This is where students work in small groups to prepare a report. Members of the group assume responsibility for preparing rough drafts of various sections of the report. The drafts are reviewed by each member of the group and suggestions are made for revision. Then the final draft is prepared and submitted, the group is recommended or criticized for their effort. In this process they learn from each other. This idea is best to our environment or our Dadaab settings. This is because others like the use of transparencies cannot be used due to lack of the resources (projector) and others are time consuming and difficult in the preparation.
Question 6 (1 mark)Look at the Common Laboratory Equipment in page 4 of Handout 1.1 – Primer on labs. If you have any of the equipment in the picture at your school or you can find, make, or adapt something to fit the same purpose, list it below.
The list of common laboratory equipment that are found at my school or I can find them, make or adapt something to fit the same purpose are as follows:
Ø Graduated cylinder
Ø Test tubes and rack
Ø Wide mouthed bottle
Ø Florence flask
Ø Burette

Ø Triangle.
Question 7 (1 mark)List below the chemicals that you can find at your school or that you can get from other sources.
The chemicals that I can find at my school or I can get from other sources are as follows:
The chemicals are very many which I cannot mention them all but to highlight a few of them are; sodium chloride, hydrochloric acid, sulphuric acid, sodium hydroxide, potassium hydroxide and ammonia hydroxide.
Question 8 (1 mark)List other things that you have or do not have that might affect your ability to have students do laboratory work (e.g., no source of natural gas for lab, lack of key chemicals, no fume hoods or safety features).
Other things that I have or I don’t have that might affect my ability to have students do laboratory work are listed below:
Ø Source of natural gases
Ø Fire extinguishers
Ø Some important chemicals
Ø Ring stand (with rings)
Ø Condenser. (water cooled)

What was the most challenging chemistry laboratory or demonstration that you did as a teacher? Why?
• Class control because the number of student were very many.
• Shortage of equipment since the equipment were not enough.
• Breaking of apparatus because the learner really do practical hence they are not used to be handling apparatus.
• Time management was also a problem since there is a distance learners cover between the classroom and the lab leading to wasting of some minutes hence affecting lesson time
• Large group because of the laboratory space and not enough functioning apparatus force me to used large group instead of small group hence these was also a challenge.
• Sinfulness of girls to participate in class was also a hindering factor I encountered.
Question 4
Read pages 1 and 2 until the heading Laboratory Reports (Handout 1.1 – Primer on labs) and answer the questions that follow. These pages are from a laboratory text called Heath Chemistry.
Question 4.1 (1 mark)
On page 1, in paragraph 3 this writer says: “Rather than using laboratory work to supplement study in the text, the text is used as an important source of information to supplement the scientific investigation that centers around the laboratory.”
Consider these two approaches to teaching and learning chemistry: (i) Using lab work to study the text; (ii) Using the text to study scientific investigation in labs. Which teaching approach do you think is best? Which approach are you familiar with in your own learning and teaching of chemistry? Explain in 4-5 sentences.
To me, approach 2 is the best because it provide basic information that guide and help the students to do scientific investigation and prove for themselves that was said by a scientist very safely and find concrete answers otherwise student will get more risk and end up getting more confusion if they are asked to conduct an experiment without any reference materials even the corrosiveness of concentrated acid and other metals like potassium, lithium and carbon monoxide the student may not know without the text first, therefore using the text to study scientific investigation in labs is very vital.
Question 4.2 (1 mark)
Page 1 recommends carrying out experiments in three phases: pre-lab session, laboratory work, and post-lab session. In 4-5 sentences, summarize why they recommend this.
The recommendation is very helpful to both the teacher and the learners in such a way that the teacher will present the content in a systematic method that enable the students to easily understand the content , also it enables the learners to develop scientific skills that are very helpful in their future, this minimize the assumption the teacher could make that his the mostly knowledgeable and his role is to pass knowledge to the learners, lastly it gives equal opportunity to all leaners to eithers learn at the same speed /level or to participate in all stages of learning.

Question 4.1 (1 mark)
On page 1, in paragraph 3 this writer says: ?Rather than using laboratory work to supplement study in the text, the text is used as an important source of information to supplement the scientific investigation that centers around the laboratory.?
Consider these two approaches to teaching and learning chemistry: (i) Using lab work to study the text; (ii) Using the text to study scientific investigation in labs. Which teaching approach do you think is best? Which approach are you familiar with in your own learning and teaching of chemistry? Explain in 4-5 sentences.
The best approach to use when teaching and learning chemistry is the use of lab work to study the text. students understand deeply and better a practical lesson than a theory lesson since practical involves the use of all most all the senses hence there is high retention and remembrance of the content learnt.
For me am familiar with both the approaches whereby there are some lessons you are suppose to carry out an experiment but you don’t have the materials needed then you have no option but to use it to supplement your lesson.
Question 4.2 (1 mark)
Page 1 recommends carrying out experiments in three phases: pre-lab session, laboratory work, and post-lab session. In 4-5 sentences, summarize why they recommend this.
PRE-LAB- Here is to prepare the students for the work to be done in the lab. It also acquaint them with the problems being investigated and make it clear what is being expected in the lab. Here the students are informed the dos and the don’ts in the lab.
LAB- Here the students carry out the laboratory experiment either in groups or individually. The teacher also provide procedural hints and suggestions when necessary. Here the teacher does close monitoring of what is being done by the students.
POST-LAB- At this time the students completes the questions and calculations that were given by the teacher. The teacher makes a follow-up of what has been done and conclude the lesson. Here the teacher encourages the students to draw their own conclusions based on experiment.

Question 4.2 (1 mark)
It’s quite essential to adhere these three phases. Pre-lab provides hint of the subsequent lab session. Lab allows the experiment to be done by following the procedure and enables recording of the observation. Post- lab enhances the confirmation of the concept by use of the results from the experiment. It also correlate, interpret and evaluate the data they have obtained.
Question 5 (1 mark)
Read the Laboratory Reports section on pages 1 and 2 of Handout 1.1 – Primer on labs. These ideas for getting students to report laboratory results without doing a traditional lab report. Choose one idea that you would like to try and write it below. Then state in 1-2 sentences why you would like to try it.
Even though all are useful I prefer to use transparencies because it saves time as student are issued with acetate sheet and pens to prepare tables of the data prior to the actual class. Students can be shown by use of overhead projector.
Question 6 (1 mark)
Look at the Common Laboratory Equipment in page 4 of Handout 1.1 – Primer on labs. If you have any of the equipment in the picture at your school or you can find, make, or adapt something to fit the same purpose, list it below.
Burette, evaporating dish wire gauze, funnel, test tube, cylinder, burner, conical flask, triangle, pipette plastic wash bottle, test- tube rack, beaker, tongs, etc
