This question depends a bit on the learner. To me, the preferred ways of approaching tasks has to take into account the student's learning style and attention span. For me, students need to use a calendar to know what needs doing first. Knowing and completing the immediate tasks requires students to use their notes which are well done with the most important points delineated, perhaps the course syllabus, a quiet place with the correct materials, and the attention to stay working until the immediate tasks are finished. Memorization using mnemonics helps with studying such as FANBOYS to remember the coordinating conjunctions(for, and, nor, but, or, yet, so). If students have to take a break, use a timer to get back soon after a break. Stay serious and look at the assignments coming up so that good time management becomes a skill. Focusing on the task at hand while blocking out other sounds and distractions helps accomplish tasks faster. If reading is required, make sure you understood the material by breaking in down into the important points and explaining it to someone else. Hope this helps.
I like to approach things chronologically and orderly. I try to set up a list of sub-tasks that will be needed to complete the final task. I like to create mini deadlines to check my progress. Having a rubric to adhere to helps keep me organized.
I would say pay attention to the kids learning style and do not give them something where they would loose their attention after a while. If they do not understand you can walk them through the problem and help them understand using diagrams, visuals, etc.
As a student who has been going to school for almost 14 years of my life, I know that I prefer tackling my studying straight away. I would read a paragraph from the textbook first, summarize, take notes, and highlight key vocabulary. Afterwards, I would take online quizzes or textbook quizzes about that subject. Afterwards, I would make flashcards about the subject and make sure I memorize and learn the keywords. Successful students make flow charts or diagrams of what they're learning because often times, information from one chapter coincides with another.
