For some people, December is the start of the Christmas season, for others, it’s the start of the exam season. In preparation for final exams, students generally spend long period of time memorizing information and formulas, yet a team of UBC researchers found that to succeed, students should study properly, not study more.
Bruce Dunham and his research team studied statistics examinations using a tool called Bloom’s taxonomy and found a miscommunication between students and professors when it comes to assessments. Students will practice low order cognitive skills (LOCS) such as memorizing while professors will test high order cognitive skills (HOCS) such as analyzing data. There are six cognitive levels which the UBC researchers combined into five: remembering, understanding, applying, analyzing and evaluating and creating. Based on these levels, the researchers then categorized statistics examinations questions–a process called “Blooming”.

From their research, Dunham’s team was able to address the common misconception of studying more to achieve higher grades because this method, as many students have found, does not always yield the best results. Instead of memorizing how a problem is solved and the exact equations the professor used in their solution, Dr. Dunham advises students to understand the concepts and learn the skills that the question tests.
The advances in technology has rendered looking up and memorizing information from a book almost useless since the information is generally readily accessible through technology. Therefore, professors have begun to redirect their assessment focus from solely memorizing to being able to interpret or analyze data. The impact of technology continues by supporting students’ learning in the form of online homework, online discussion boards and in-class response systems. In fact, the effects of these newly implemented learning support systems on students’ academic performance was also studied by Dunham’s team. However, due to the lack of baseline data and difficult conditions for collecting data, Dunham’s team only found weak evidence to support the positive impact of technology-driven learning support on students’ academic performance. As students ourselves, we believe that technology and the learning support provided for us have presented positive effects to our learning and the students we interviewed had similar opinions.
As technology evolves, so does our education system and thus the change in focus for assessments. Dr Dunham talked about the “flip classrooms “for the future where students do all materials online ,discuss the questions online and they go to class only if they have some confusions.The evolvement of technology is beneficial for students because they can learn in their own pace. Instructors will benefit from that as well. Therefore, students and professors should appreciate the progress of technology and the usage of that in learning and teaching.

There are different types of food or substances that create allergies in humans. One of the most common allergies is peanut allergy.
According to MedicineNet.com, peanut allergy is the allergy which is common among adults and kids, but it usually occurs in children under 3 years old. This kind of the allergy has 80-90% of symptoms are related to skin, for example, skin rash and itching ;despite of that it has some severe symptoms; it affects the respiratory system, gastrointestinal and cardiovascular system; therefore, it might be fatal.
In order for doctors to diagnose patients with peanut allergy, there is a test called skin prick test (SPT). However, if the result is positive, it does not mean that you have peanut allergy and doctors need to take a blood test (peanut specific lgE levels) to make sure that it is peanut allergy.
Good news is that recently, scientists find a cure for this allergy that might save people’s life. In this study, scientists achieve that probiotic treatments will have a positive effect on people who diagnosed with peanut allergy and in the most cases it will protect people from having this allergy reactions.
Same study shows that probiotics and peanut allergies have negative correlation. Probiotic is a type of bacteria that is beneficial for our health. It will make our immune system strong and has positive effect on our gastrointestinal system and therefore, probiotic treatment is most likely to prevent people from food allergies and more specifically peanut allergies.
watch the following video to find out the details about the effects of probiotic on the peanut allergy.

To conclude, if you have already diagnosed with peanut allergy or your kid has this kind of allergy ,instead of being worried about the reactions of your kids to peanuts put probiotics in their daily diet; by using probiotics not only you will save them from fatal reactions to peanuts but also you will make their immune system stronger and therefore, more protective to other diseases.

People across the world, especially in North America, cannot live without taking caffeine daily. However there are different food that contain caffeine , coffee has the highest amount of caffeine and is the most popular one . According to Coffee Association of Canada, In 2013, 65% of Canadian adults over 18 drink coffee daily. There are several reasons for this consumption. Some use it to become alert and awake, while others drink coffee to be relaxed. Although, coffee has more roles than relaxing on our health ; one of its important roles is its role on Parkinson’s disease.
In one study, scientists proved that coffee has a positive effect on Parkinson’s disease. Parkinson’s disease(PD) is a progressive disruption of nerve system that affects the movement and it usually happens to the elderly. In the other words, PD will occur when Dopamine is not produced in nerve system. Dopamine is responsible for movement in our body. Coffee has a neuroprotective role and will react with our brain nerves and increase the level of Dopamine and therefore, reduces the risk of Parkinson’s disease.
The other study also showed the negative correlation between coffee and Parkinson’s disease. Researchers did a study to see if this association is equal in women and men and after they did an experiment they found that coffee will prevent both men and women from PD, however, the probability is higher in men.
To conclude, if you drink coffee 3-4 cups a day , you will protect yourselves from some fatal diseases such as Parkinson’s disease or if you have already diagnosed with a PD, you can reduce the symptoms by taking this amount of caffeine in your daily diet; therefore, you will live longer and happier.
To find out how caffeine have an effect on PD in details, watch this video below.
