Week 6: Design Related Task- Product Testing and Analysis

TESTING AND ANALYSIS OF SALT & VINEGAR CHIPS

Product:                       Salt and Vinegar Chips
Claim:                          Salt and Vinegar chips do not vary much in taste
Pre- test Activity:         Discussion of the range of salt and vinegar chips and of claims made by manufacturers
Requirements:            1. Committee of students obtain samples of 5 different brands of salt and vinegar chips. A quantity of tasting paper plates, a quantity of unidentifiable containers, and scarves for blindfolding.
                                      2. Recorder who will note the taste panel preferences into a spread sheet or a table directly on a tablet or laptop
Procedure                   1.  Committee appoints a taste panel of about 6.

                                      2.  The chips are placed into the numbered, unidentified containers (out of sight of the rest!)
Each taste-tester is blindfolded and eats a sample of each salt and vinegar chip
                                      4.      The votes of each taste tester for each of the chips are recorded into a spreadsheet or table directly on a tablet or laptop.
                                      5.      Containers are identified, and another taste panel  test.

A series of 6 lessons was developed from the Stage 6 HSC syllabus unit of Food 
Product Development to cover the above.

Week 4: Learning Cycles and Guided Inquiry Part 2

Virtual Tour


Stop 1 (Wikipedia)

     1.    A case study is a descriptive, exploratory or explanatory analysis of a person, group or event.
There are 2 types of case studies:
-          Prospective; criteria are established and cases fitting the criteria are included as they become available.
-          Retrospective; criteria are established for selecting cases from historical records for inclusion in the study.
     2.    Case studies can be used to teach many examples of food processing, environmental sustainability, and food product development.


Stop 2 (MindTools)
  1. MindTools defines a case study as a form of problem-based learning, where you present a situation that needs a resolution. Yes it does, it fits with the retrospective way mentioned in stop 1.
  2. Case studies are a great way to improve a learning experience, because they get the learner involved, and encourage immediate use of newly acquired skills. They require participation and deliberate application of a broad range of skills.
  3. Use case studies when understanding the concept is more important than memorizing correct responses.

-     Case studies can be used to evaluate past problem solving. People can be asked what they'd do in that situation, and think about what could have been done differently.

-     Using case studies when learning about the effects of canning food, environmental sustainability, finding out what different companies are doing to sustain the environment. 

Stop 3 (Wordpress Blog)

1.    Case studies allow a lot of detail to be collected that would not normally be easily obtained by other research designs. The data collected is normally a lot richer and of greater depth than can be found through other experimental designs.
2.    One of the main criticisms is that the data collected cannot necessarily be generalised to the wider population. This leads to data being collected over longitudinal case studies not always being relevant or particularly useful. 

Stop 5 (Waiter, there is a gene in my food)

1.    Teaching GMF to students. We teach them different examples of how different companies genetically modify foods.

Stop 10 (Sustainability)
1.    Teaching students examples of tactics that different businesses use to promote environmental sustainability for food

Week 4: Learning Cycles and Guided Inquiry Part 2

Trackstar

1. Learning and Teaching- Atherton

Kolb's Learning Cycle

Suggests that there are 4 stages in learning and they follow on from each other.
1. Concrete Experiences – “knowledge by acquaintance”, direct practical experience (doing and experiencing)
2. Reflective Observation – what the experience means to the experiencer  
3. Abstract Conceptualisation – follows on from Concrete Experiences it is the comprehension of concrete experiences
4. Active Experiment – follows on from Reflective Observation this is where the theory is practiced 
Kolb Model

 How are learning styles (Honey & Mumford) different to the Kolb model?

Honey and Mumford have built learning styles around the Kolb Model where they identify individual preferences of learning. They Indicate that:
  • Activists prefer doing and experiencing and they fit into the concrete experiences 
  • Reflectors – Reflect and observe and they fit into the Reflective Observation 
  • Theorists – want to understand reasons, concepts and relationships and they fit into the Abstract Conceptualisation 
  • Pragmatist – likes to have a go and see if it works and they fit into the Active Experiment


What does Kolb mean by 'Ways of Knowing' and 'Ways of Understanding'? How  do these qualities interact? 
Ways of knowing works with concrete experiences and abstract conceptualisation these two work together – by direct experience and comprehension or knowing about 

      Ways of Understanding works with Reflective observation and active experiment- by using denotation by thinking connotation  

What are the implications for this model within the TAS specialisations?
In food technology, this can be a useful style as students can learn by experimenting and cooking. Hands on work can lead them to discover different cooking styles, techniques and the understanding of properties of food.

2. Experiential Learning- Neil

What is experience?

Experience refers to the nature of the events someone or something has undergone. Experience is what is happening to us all the time – as long as we exist. The word experience has two emphases, present and past, and refers to two different views. Experience, used in the present tense, refers to the subjective nature of one’s current existence. Humans have a myriad of expressions, behaviours, language, emotions, etc. that characterize and convey our moment-to-moment experiences. Experience, used in the past tense, refers to the accumulated product (or residue) of past experiences.

What is experiential learning?

Experiential learning has come to mean two different types of learning:
  • Learning by yourself and
  • Experiential education (experiential learning through programs structured by others)

Experiential learning by yourself
Learning from experience by yourself is education that occurs as a direct participation in the events of life. It includes learning that comes about through reflection on everyday experiences. Experiential learning by yourself is also known as informal education and includes learning that is organised by learners themselves.

Experiential education (experiential learning through programs and activities structured by others)
Principles of experiential learning are used to design experiential education programs. Emphasis is placed on the nature of participants’ subjective experiences. An experiential educator’s role is to organize and facilitate direct experiences of phenomenon under assumption that this will lead to genuine (meaningful and long-lasting) learning. This often also requires preparatory and reflective exercises.

What is experiential education?

In experiential education, the student becomes more actively involved in the learning process than in traditional, didactic education. For example, going to a zoo and learning through observation and interaction with the zoo environment is experiential and in contrast to reading and talking about animals in a classroom. The main difference here, from a pedagogical point of view, is that the educator who takes his/her students to the zoo rather than stay in the classroom probably values direct experience more highly than abstract knowledge.

Experiential Learning Cycles
Experiential Learning Cycles are models for understanding how the process of learning works. They are distinct from other models of learning, such as behavioural model or social learning models, in two notable ways:
  • Experiential Learning Cycles treat the learner’s subjective experience as of critical importance in the learning process. ECLs draw on experiential education principles, which are largely based on the educational philosophy of John Dewey
  • Experiential Learning cycles propose in iterative series of processes which underlies learning. Depending on the model, there is anywhere between one stage (experience alone) through to six stages of learning to be considered.

Experiential Learning Cycles are commonly used to help structure experience-based training and education programs.

Progressive, "Free"
Education
Semi-structured
Education
Traditional, "Structured"
Education
Free, permissive, learner-driven, practically-oriented, progressive education
Semi-structured education, e.g., the subjectivity of learning experience is recognized, however the experiences are guided somewhat via structured planning and reviewing processes
Structured, knowledge-oriented, competency-driven, normative, traditional education






3. Emerging perspectives on learning, teaching and technology

There are some weaknesses in the Kolb cycle and due to this it is necessary to construct another model such as the one below. This includes Kolb's beliefs and at the same time confronts the weaknesses that have been found. 

Revised Experiential Learning Cycle
The idea behind this model was to include the observations of the learners' own subjective reality as a starting point for experience. The different elements of the above cycle are explained in order below: 


  • Disruptive Experience: Experience that is a disruption of the habitual manner in which an individual experiences things. This is in contrast to a non-reflective experience borne out of habit.
  • Emotion Inventory: Inventory of emotions that are created by the disruptive experience.
  • Reflective Observation: Observations concerning the experience and reflection upon the event including causes, possible effects, etc.
  • Conceptualization/Hypothesizing: Further processing of the experience; creating concepts to explain the experience and construction of explanatory hypotheses.
  • Addressing: The concepts and hypotheses that have been constructed are formulated and the experience is addressed in some manner. There is an attempt to predict future experience. This may involve planning, active experimentation, or cautious testing.

Experiential Teaching and Learning in Food Technology

Various strategies were used in the experiential  learning activities for a large group of students studying human nutrition and food science.
Experiential learning activities were done for:
1. Nutrition and Health- Dietary Intake Assessment

  • Students asked to print 4 menus
  • Students to select the menu that best resembles their own diet plan
  • Lecture on nutritional labels was given
  • Example of Nutritional label and cost was given
  • Students to then complete their own assessment for their own menu plan by using their past lecture notes
  • Complete a reflection questionnaire

2. Food Microbiology and processing- Food Safety Survey

  • Occurred outside of the classroom
  • Online food safety survey- based on their own experience and behaviours towards food safety
  • Attend lecture on food safety and spoilage of food
  • Students to complete a reflection questionnaire using their lecture notes
This strategy proved to be effective as students personalised their learning and enhances student learning by motivating the students to like and be more engaged to the course. 

The research study showed the students were happy with this type of learning

These strategies are somewhat similar to our project for TAS as our lessons are interactive, hands on and collaborating their experiences and knowledge. The only thing we could add to our lessons would be to incorporate a reflection survey or questionnaire to link their knowledge to their own experiences and this would fall into the above learning model.

Task 4: 

What do we want the kids to do?

  • Watch the video and
  • Take down the important notes.
  • To complete a worksheet based on the video (general and specific questions related to the topic)
  • Class discussion of the answers to the worksheet focusing on analysis, elaboration of key ideas, justify their thoughts/answers/opinions and potential new ways of applying the content to their lives.
What are we asking the kids to give us back to show us that they understand their task?
  • Students must also answer a quiz to illustrate their understanding of the video
  •  Half page written response that ties the key ideas of the video content (scenario based, a news report) 

Webquest was downloaded for the next part of the lesson and a series of tasks were to be completed.

Week 3: Guided Inquiry

GUIDED INQUIRY

  • Guided inquiry supports a constuctivist approach
  • Guided Inquiry teachers lead students through projects by giving them starting questions, prompting new discussions with ideas and methods, or acting as a supervisor in other ways


Inquiry process
provides
• a means of
integrating
curricula and leads
to holistic,
multidisciplinary
learning
• a range of learning
tasks appropriate
for students at
different
developmental
levels
• opportunities to
embed instruction
in authentic
contexts
• an active role for
students to share
in the
responsibility of
planning
• support for
developing
independent
learning skills
• a context for
cooperation,
collaboration, and
community
building
Implementing a guided inquiry approach from week 2

Task 2: Students are to get into groups and discuss what knowledge they have about nutrition and the food nutrients. Then they get given a specific nutrient and they must explain the role of that nutrient and present it to the other groups

Sequencing Learning Activities
  • What are Nutrients? and why are they important?
  • Students to get into groups and discuss nutrition and nutrients in food
  • Gather all the ideas and draw a mind map
  • Research the specific nutrient online and collate all the information found.
  • Write up all the information found onto a document
  • Present the information to the class



    The Inquiry Process:
    Activating
    Choosing a theme or topic.
    • Identifying and recording prior knowledge.
    • Asking initial questions.
    • Exploring and selecting primary and secondary sources.
    • Planning for inquiry
    Acquiring
    • Gathering, processing, and recording information.
    • Focusing the inquiry.
    Applying
    Planning to express learning.
    • Creating performance(s)/demonstration(s)/product(s).
    • Celebrating and reflecting  



    Another Example of Guided Inquiry 
    Task: With the nutrient group that is given to you, create a 5-7 min presentation explaining what it is, examples of foods where it can be found (sources) and the role of that the nutrient group in the body
    Put students into groups. (By doing so you are able to put the different learning styles together and make sure no one is excluded).
    • Assign the groups a different nutrient group.
    • Allow the students to look up the nutrient group online. (Basic information to start off with such as what is it?)
    • Students look up sources of the nutrient
    • Students look up the function that the nutrient plays in the body
    • Students take the information and put it into a presentation to show the class.
    • Teacher assesses this presentation to evaluate what the students have learnt
