Revised Podcast

The following podcast demonstrates how to compute mean, median, mode and range. I prepared it for 4^th grade students.

PODCAST TOPIC

I am going to create a podcast on mathematics. It will explain how to use protractor to measure angles.

“Techniques That Reduce Extraneous Cognitive Load and Manage Intrinsic Cognitive Load during Multimedia Learning”

            Multimedia learning is based on use of words and pictures, which are presented via computers. It should be formed on solid conceptual knowledge that is applicable to the subject matter.  Below please see the figure that illustrates the cognitive theory of multimedia learning:

            Multimedia learning is a significant way of conveying information. Sounds and images capture students’ attention and make discussed topics easy to comprehend. It is also important to point out that learners’ meet various obstacles to multimedia learning, which take place when the material contains extraneous material (material includes non-essential information in lesson) or it is inadequately laid out.  Another problem that learners have is essential overload that can occur with multimedia learning. It happens, when students do not have relevant prior knowledge; when the material is complex and unfamiliar; the material is presented at a very fast pace.

            “Meaningful learning depends on holding corresponding words and pictures in working memory at the same time” ( Moreno, Mayer, p. 140). That is the reason why overloading the working memory unables learning. Research shows that students, who received a narrated animation in which corresponding segments of the narration and animation were presented at the same time, comprehended material better that those, who listed to the narration before or after the animation.

            Multimedia learning is a significant new way of transmitting knowledge. It helps students comprehend new information using sounds, animations and words. The computer based learning still needs to be worked on and perfected, because of its extensive cognitive load. The multimedia lessons should be design and planned accordingly, so that the working memory is not loaded with irrelevant information. The lectures should show narrations and animations at the same time, they should be also based on students’ prior knowledge and convey only important information.

Technological pedagogical content knowledge (TPCK)

Technological pedagogical content knowledge (TPCK) is a framework that incorporates the three main factors of knowledge: content, pedagogy and technology. The factors interact with each other to create effective teaching with technology.  The TPCK not only requires teachers to have a great content knowledge, pedagogical techniques that convey the knowledge, and skills  to learn and use technology, but also ability to integrate these elements in order to be create successful and efficient learning environment. The framework entails teachers to use technology and pedagogical techniques constructively to teach content.

 In my opinion a great implementation of the TPCK framework in elementary school education are games, graphs, etc. They should be creative and fun, but at the same time they should focus on conceptual topics, themes and subjects.

 The TPCK framework is design to make teachers involved into designing curriculum. The authors state that “ Teachers are active participants in any implementation or instructional reform we seek to achieve,  and thus require a certain degree of autonomy and power in making pedagogical decisions.”  I agree with that statement. I believe that teachers should be involved in deciding what is taught to students, and how that knowledge is communicated.
