  • Unified Learning Model is a model that how we learn. It is a resulting model for teaching and instruction. Even thought there are many theories on instruction and learning in the current literature, they are just containing limited model and theories on isolated specific aspect of learning and teaching. Also each theories has its own specific terms and principles, so these theories are not suitable for understanding universal interactions in teaching and learning.
  • Presenting clicker questions in the class also stimulates students’ attention to the important concepts. Also if used in a fashion where contents are linked together and constructed in a way that students learn from previous lectures as well as requiring students to think critically on the discussion topics will increase students’ deep understanding. Instructors could cover the most important and critical topics in the class time and in addition to in class activities, they can direct students to other additional information resources. Shortly in order to benefit best from clickers’ instructors should consider writing good questions and design and adapt the content flow accordingly to new system.
  • Designing a lesson using clicker is simple but it requires knowledge of designing a presentation with Power Point software. In order to pose a question in the classroom instructor should create a clicker slide. Some of the clicker systems in the market can be integrated with Power Point that allows creating - integrating clicker slides and recording students’ responses directly without any extra effort. The only thing instructor should worry about is reminding students to log-in in to clicker system and presenting the Power Point slides in the class. During the presentation, students’ responses recorded automatically and displayed very quickly (Draper et al., 2002). In this sense use of clickers in the classroom heavily depends on instructor facilitation. Additionally recorded data could be used to run complex calculations, trend analysis, and data modeling by using software provided by clicker companies or other third party products.
  • Clickers use a simple networking protocol to send a signal form student handset (transmitter) to instructors’ computer (via Receivers). Clickers handsets look like TV remote controls. Many clickers just support multiple-choice questions that require students to key the right answer. Some of the clickers have 10 digits to enter answer (Elliot, 2003) and some of the clickers also allows entering text data to send to instructor (Oder, 1997). In the classroom there should be some transmitters that gather signals when students click to a clicker and send them to instructors’ computer to be recorded via the clicker software. The transmitters work with radio-frequency (RF) or infrared. The physical attributes of classrooms are more important in the clicker case that may require some adjustments. Also it is suggested (Betty, 2004) to add bigger presentation screens with a good projector, wireless microphones and sound systems into these classrooms in order to fully benefit from these systems.
  • Pod casting allows instructors to upload lessons to a podcast web service that students can download to their iPods. Students can automatically follow podcast feeds for updates in content by using software called pod catcher. That will enable students to listen and learn the information on their phase, replaying the materials in order to have greater comprehension, creating a chance to review exact materials that the lecturer covers before exams and helping instructors to review their lessons to make further improvements (Gilroy, 2006). iPods allow students to have freedom to listen lesson materials downloading in any podcast form in order to prepare for their classes in anyplace and anytime they would like to. Use of additional microphone can also create their recordings in anyplace and anytime (Sathe & Waltje, 2008). In this sense podcast is not only a knowledge delivery it could be also used interactively as a reflection tool
  • Mobile technologies could facilitate collaboration and interaction, accessing, discovering, discussing, and sharing environmental information with use of SMS services (Cavus & Uzunboylu, 2008). There are some models of learning with mobile phones. These are a ‘Push’ model which allows the school or the teacher to send out messages to learners enrolled in a specific lesson , a 'Pull' system which enables learners to receive information using a menu system, an interactive system which enables learners receive questions then answer, receive feedback (Cavus & Uzunboylu, 2008). Most other usage of mobile phones includes short answering, ranking, matching, fill in blanks, true/false, multiple choice questions (Sharma & Miller, 2004; TxtTools, 2010). Additionally to these interactive benefits SMS can be used to alert students about a certain event or to announce specific facts.
  • Educational institutions also may run their free services in the campus but they should consider the costs. For example, in order to run SMS traffic, mobile operators should have a node in the network called SMS Center (SMSC) and this center could be a third party aggregator (provider) that could connect to other operators (Nix, 2007). This also enables educational institutions to have their own service centers to run much cheaper than direct connections to operators. These kinds of aggregator are relatively easier to develop an application using Simple Object Access Protocol (SOAP) or HTTP protocol ( This kind of implementing could reduce costs of ownership efforts and expertise requirement.

    2. 2. Choosing the Right Technology 1
    3. 3. What Does Learning Theories Tell Us ?• The Unified Learning Model (ULM) 2
    4. 4. General Rules of Learning • Rule 1. New Learning Requires Attention: “Teaching and instruction are about getting learners to attend things”• Devices should be able to directing learners’ attention.• Asking questions is a good method to direct attention to a specific point. 3
    5. 5. General Rules of Learning • Rule 2. Learning Requires Repetition: “Teaching needs to include retrieving and for skills, practice”• Teachers should build statements in questions according to learners existing knowledge. This will lead retrieving previous knowledge of learning as well as using it in variety of situations. 4
    6. 6. General Rules of Learning • Rule 3. Learning Is About Connections: “Effective teaching and instruction are about insuring that learners are attending proper connections”• Teachers should give opportunity to test the validity of learners existing connections.• Analysis questions are good for this purpose. 5
    7. 7. General Rules of Learning • Rule 4. Some Learning is Effortless; Some Requires Effort: “Since school is about deliberately learning specific information and skills, learning in school will be difficult (needs effort)”.• In class interactions are important but not the only way of flexible discovery of knowledge. 6
    8. 8. General Rules of Learning • Rule 5. Learning is Learning: “At the level of neuron, human learning is human learning, the only difference comes from previous experiences. What we already know impacts what we can learn next or more• easily” The learner is unique in personality so we may build on his experiences to bring him a mastery level. (Personal learning).• It is important to keep track of learners activities (such as his responses into data base for further analysis) 7
