Online Surveys and Questionnaires


Do you really trust everything you see and read online?



Supposedly the anwer will be NO - as the question itself is suggestive.

Not only obviously naive people make easy prey for intentionally misleading sites. In may cases, the internet-based information  may be even dangerous, if you apply it without common sense and without a wider knowledge of the problem - e.g. information about health problems connected to hardselling sites.

Nevertheless, we can also find theories and questionnaires are more or less trustworthy, at least for the purpose of orientation. The analysis of personal learning styles is one of them.

_______________________________________________

Everybody is active sometimes and reflective sometimes. Your preference for one category or the other may be strong, moderate, or mild. A balance of the two is desirable. If you always act before reflecting you can jump into things prematurely and get into trouble, while if you spend too much time reflecting you may never get anything done.

If you overemphasize intuition, you may miss important details or make careless mistakes in calculations or hands-on work; if you overemphasize sensing, you may rely too much on memorization and familiar methods and not concentrate enough on understanding and innovative thinking.

In most college classes very little visual information is presented: students mainly listen to lectures and read material written on chalkboards and in textbooks and handouts. Unfortunately, most people are visual learners, which means that most students do not get nearly as much as they would if more visual presentation were used in class.

Sequential learners may not fully understand the material but they can nevertheless do something with it (like solve the homework problems or pass the test) since the pieces they have absorbed are logically connected. Strongly global learners who lack good sequential thinking abilities, on the other hand, may have serious difficulties until they have the big picture.

TASK 1: Fill in the questionnaire at http://www.engr.ncsu.edu/learningstyles/ilsweb.html.
What do the results tell about you? How do you feel about it? Insert your ideas into the comments to this blog entry.

TASK 2: Using online questionnires to research data 

1.
Choose a topic you are interested in; your research field is learning and teaching languages.
Formulate a Research Question or Hypothesis: e.g. "The commuting students have better study results."
Develop a real, interesting research question - be considerate! This task is not meant to become a mock-research. Try to imagine a topic you could develop into a bachelor thesis.

2. Prepare several  survey questions to get data which will help answering your Research Question or confirm your Hypothesis. Include also questions mapping the profile of your respondents (age, field of study...). Write the questions into a text editor, reconsider and reedit. Ask the tutor for feedback before publishing the research.

3. Explore the sites linked below, their requirements and the formats of input and output.
Make sure you will get your data in raw version - not just a summary in per cents. Choose a site you will use.
Put the questions online using any chosen free format.
Publish the link to your survey in your websitehere and here in the blog comments, and ask more friends (best by email) to fill in your online questionnaire. Each of you should have at least 25 respondents.

4. Go to each other's sites and answer the questions. 


5. Prepare an attempt of statistical survey for the next lesson.

Working with audio

Audio material is regularly used when teaching speaking and listening in foreign languages. Therefore the teachers and the students should be able to edit and modify audio as well as texts.
Probably the best freeware available for editing sound is called AUDACITY.


Audacity Basics - you should be able to
- install Audacity and the lame library which enables export to mp3
- open a file in Audacity
- edit the file: cut and paste, fade in/out, change speed, delete, add silence
- create a new file
- combine two files (e.g. speech + background music)
- inserting silence (e.g. as a space for an answer)
- changing the speed or pitch (carefully!)



TASK 1 - TEACHER'S JOB
Browse Youtube for videos suitable for the topic you chose for HotPot tasks.
View, listen and choose; consider the target level and age!
Convert the video to mp3 using an online convertor.
Cut out a part of the recording, add an appropriate task and illustration and publish all that in your HotPotaoes index webpage (see the related blog entry for details).


TASK 2 - AN EXAMPLE OF A STUDENT TASK
You have just become a radio reporter!
Listen to the story of a toddler falling into a gorilla cage at Youtube. Another link HERE.
Find more stories covering the same or similar incidents.
Download the material converted into mp3.
Combining the available audios, create a thrilling radio report about the troubles caused by irresponsible ZOO visitors (max 70 seconds long).
If you feel like it, find more sounds (e.g. crowd shouting, Zoo animals sounds etc.).
Upload the story with an appropriate illustration to your web.

OR choose your own topic, download materials and edit your own story!

You can use Free YouTube to MP3 Converter to get audio from youtube easily, or find xonline converters, eg. Convert2mp3.


TASK 3 - EXAMPLES OF GOOD TEACHING PRACTICE
2. What does the word "podcast" mean? Go to Podomatic, create an account and browse the site. How can we use it in teaching English?

Good examples - Teacher Luke at PodomaticSplendid Speaking for advances learners

Podcast on podcasting in ELT


HOMEWORK
1. Record comments to the 12 images in your gallery (1 minute max., save in wav file)
2. Edit the recording in Audacity, add background music, cut out noises etc.
3. Export the wav to mp3
4. Upload the mp3 to your website

REMEMBER - before editing, create a backup copy of the original!

Examples of galleries with audio comments created by your colleagues:

http://www.dzblecht.wz.cz/My%20home%20town.html
http://skipit.wz.cz/galerie.html

Sound files extensions:
wav -  Standard audio file container format used mainly in Windows PCs. Commonly used for storing uncompressed (PCM), CD-quality sound files, which means that they can be large in size—around 10 MB per minute. Wave files can also contain data encoded with a variety of (lossy) codecs to reduce the file size (for example the GSM or MP3 formats). Wav files use a RIFF structure

mp3 - compressed, MPEG Layer III Audio. Is the most common sound file format used today

flac - Free Lossless Audio Codec
ape - Monkey's Audio lossless audio compression format
ogg - A free, open source container format supporting a variety of formats, the most popular of which is the audio format Vorbis; compression similar to MP3

webm - Royalty-free format created for HTML5 video
aiff - Standard audio file format used by Apple. It could be considered the Apple equivalent of wav

Sluchové pole (nebo oblast slyšitelnosti) je rozsah všech zvuků, které dokáže lidské ucho vnímat. Vnímání zvuku je u člověka omezeno slyšitelnými frekvencemi (přibližně 16–20 000 Hz). U každé frekvence je odlišný rozdíl intenzit, jež slyšíme. Lidský sluchový orgán je nejcitlivější v oblasti frekvencí 1–5 kHz.

Editing Images

Visual support is vital in any teaching situation. As English teachers, we use pictures of objects to teach vocabulary, photos of situations to stimulate communication, authentic visual materials to teach realia and culture...

What characteristics of an image influence its effect on remembering the vocabulary?
  • context or the absence of context
  • vivid colours
  • contrast
  • golden ratio
  • the size of the target object

 WHAT ARE THE KEY SKILLS IN THE FIELD OF PHOTOGRAPHY FOR THE ENGLISH TEACHER TO MASTER?

My suggestion:
1. Basic knowledge of the electronic image formats and their specifics.
2. Basic editing abilities: crop, contrast, colour adjustment
3. Basic photo-making skills and knowledge (to be able to prepare original materials, and to document school events, projects, students'activities and products).

4. Advanced editing abilities - collage (to create more original materials, and to be resistant to hoax), inserting text to the image...

Typical Viral :D

Any other suggestions?

____________________________________

HOMEWORK

1. Finish the collage and put it into your web.

2. Make several photos  expressing the school atmosphere, choose the best one, edit if necessary. Insert the photo into your Homepage (index.html) and publish online.

3. Prepare 10 images which you will use in your vocabulary teaching HotPot project. Keep them in the original size + make the same set in web version (max size 40kb per image).

____________________________________


The basic skills you should master:


1. Compressing, saving in various formats (with different extensions) and size
2. Crop (ořez)
3. Changing brightness, sharpness, hue and other basic features, and applying Nick filters.
4. Making a part of the image transparent
5. Creating a collage
6. Inserting text into a picture
7. Mastering basic hotkeys in Photoshop


Tasks:
1. Open your image in Photoshop. Work with Crop first (C). Remember - the main part of the image should be taken by the main object (or idea, or situation)
2.  Use LEVELS to set the Lightning (Photoshop: Ctrl+L, or Obraz - přizpůsobení; Menu in Gimp: Enhance - Adjust Lightning - Levels)
3. Adjust sharpness. play with blur :)

4. Working with layers and masks in Photoshop:
Open the image
Duplicate the layer (Ctrl+J)
Choose the type of layers combination (Měkké světlo, závoj...)
CZ: Přidejte masku vrstvy (možnosti - odkrýt vše nebo skrýt vše)
Malujeme do masky!


5. Use GIMP: Find two images and combine them into one, applying transparency (e.g. Donald Duck walking through Usti nad Labem :) )
6. Advanced: Try to do the same in Photoshop: make a collage of two photos!
