al The Benefits of Educational Quizzes and Tests By careertechtesting.blogspot.com Published On :: Mon, 06 Jan 2014 18:08:00 +0000 John Kleeman shared on Questionmark's Blog the ten benefits of quizzes and tests in educational practice as proposed by psychology experts Henry L. Roediger III, Adam L. Putnam and Megan A. Smith in a recent paper, “Ten Benefits of Testing and Their Applications to Educational Practice”. Here is John's summary and understanding of the paper: 1. Retrieval aids later retention. There is clear evidence from psychological experiments that practicing retrieval of something after learning it, for instance by taking a quiz or test, makes you more likely to retain it for the long term. 2. Testing identifies gaps in knowledge. 3. Testing causes students to learn more from the next study episode. Essentially it reduces forgetting which makes the next related study area more productive. 4. Testing produces better organization of knowledge by helping the brain organize material in clusters to allow better retrieval. 5. Testing improves transfer of knowledge to new contexts. There are several experiments referenced in the paper where tests and quizzes help transfer and application of knowledge. 6. Testing can facilitate retrieval of material that was not tested. Surprisingly there are circumstances where quizzes or tests, particularly if delayed, can help people retrieve/retain information that was related to that asked but not actually asked in the questions. 7. Testing improves metacognitive monitoring – by giving students scores or self-assessments, they can better predict their knowledge and be more confident about what they know and what they need to know. 8. Testing prevents interference from prior material when learning new material. If you have a test after learning one set of material before learning another set of material, it can make it less likely that the second session will 9. Testing provides feedback to instructors and lets them know what is learned or what is not. 10. Frequent testing encourages students to study. Having frequent quizzes and tests motivates study and reduces procrastination. You can see their paper “Ten Benefits of Testing and Their Applications to Educational Practice” in Psychology of Learning and Motivation, Vol 55. It’s also available for download on Professor Roediger’s publications page, in the list of papers from 2011, at http://psych.wustl.edu/memory/publications/.

al AirPano - Amazing 360 Degree Aerial Panoramas By careertechtesting.blogspot.com Published On :: Thu, 13 Feb 2014 14:53:00 +0000 After a few weeks of cold weather, cloudy skies and snow on the ground my mind begins to wander and think of where I would rather be than here. Hawaii sounds good, doesn't it? Unfortunately, my bank account usually says no to those types of dreams so I found AirPano.com which, at least, took my mind off of how cold I am and provided me a poor man's virtual vacation. AirPano.com was actually better than I expected as it provided incredible 360 degree imagery of landmarks and cities from all over the world. Their website features "over 700 panoramas showing over 120 amazing locations of all continents including Antarctic and the North Pole" and panoramas from some 50 other locations are in the works. Source: AirPano.com Much of the AirPano imagery now includes interactive pinmarks that you can click on to learn more about the places that you are visiting (as you can see on the Venice, Italy panorama below). I think AirPano is a great way to learn about other parts of the world, not only from the amazing images, but also from the history and facts about each site that they provide. Last, but not least, it is a great way to get your mind off of the cold winter weather... Visit Venice, Italy on AirPano.com Full Article CareerTechEd Instruction Online Learning

al Blended Learning and Career and Technology Education - Part III: Implications for Career and Technical Education By careertechtesting.blogspot.com Published On :: Mon, 02 May 2016 19:44:00 +0000 In this four-part series, I’ll define blended learning, discuss the models of blended learning, the implications for career and technical education, and how the Curriculum, Assessment, and Digital Delivery (CADD) areas of the Oklahoma Department of Career and Technology Education can assist in the implementation of blended learning. Here are several ways that blended learning can have a profound effect upon career and technology education: Personalized instruction – Blended learning allows for a more personalized and interactive learning experience by putting the student in charge of their own learning. Taking the best of traditional education and blending it with the power of online learning will provide the teacher an opportunity to review data, in the moment, determine where the student is at and to form instruction for the next period or the next day. Increased monitoring – The use of a student information, assessment, and gradebook systems that link to the LMS provides instant feedback on assignments and assessments. This allows the instructor to spend time reviewing student data, adjust instruction, and provide additional classroom or individual instruction. Open entry/Open exit – Blended learning fits nicely with competency-based learning and the concept of open entry/open exit. Personalized instruction and increased monitoring will allow the instructor to more accurately determine when tasks and competencies are achieved. Increased enrollments – Depending on the blended learning model and the CTE program being offered, enrollments could potentially be increased. Increased performance gains – “The Rise of K–12 Blended Learning - Profiles of emerging models” by Heather Staker profiles 40 educational entities. Not every school reported gains and some thought it was too early to verify results, but many posted positive gains when compared to the traditional classrooms within the same district. For example: “School of One - Students in summer 2009 acquired new math skills at a rate estimated to be seven times faster than peers. Students in spring 2010 showed gains that, when annualized, would equate to 1/2 to 2/3 of an additional year of gain. Students in spring 2010 showed significant gains across all academic quartiles.” Other potential benefits from this study include increased retention rates, an increase in teacher/parent contacts, increased course completion rates, a strengthening of curriculum offerings, and lower instructional costs. As you can see, blended learning can have the potential to benefit the student, the instructor, and the parents in a careertech setting. Again, I’m not aware of any research that helps decide if one model works better with any certain occupational area (if you know of any research in this area, PLEASE SHARE!!).
