Effective Management Information System:
Essential characteristics of an effective management information system are 1. MIS is management-oriented 2. MIS is developed under the direction of management 3. MIS is an integrated system 4. common data flow 5. MIS is based upon the future needs of the business 6. MIS is composed of sub-systems 7. MIS requires flexibility 8. distributed data processing and 9. MIS is mostly computerized.
Management Information System is established in an organization to provide relevant information to the managers to operate effectively and efficiently.
1. MIS is management-oriented:
The design of MIS starts with an appraisal of the information needs of the management. The system is usually designed from top to bottom. However, this does not mean that MIS fulfills the information needs of top management only.
 
It only implies that the information needs of the top management will serve as a basis for the assessment of the information needs of lower-level managers. In every case, the system should be designed to cater to the information needs of all levels of management.
2. MIS is developed under the direction of management:
Because of the management orientation of MIS, it is imperative that the management of an organization actively directs the development and establishment of the MIS in an organization.
It is rare to find an MIS where the manager himself, or a high-level representative of his department, is not spending a good deal of time in the system design.
 

Big data:Big data refers to the large, diverse sets of information that grow at ever-increasing rates. It encompasses the volume of information, the velocity or speed at which it is created and collected, and the variety or scope of the data points being covered (known as the "three v's" of big data).

Big data is a great quantity of diverse information that arrives in increasing volumes and with ever-higher velocity.
Big data can be structured (often numeric, easily formatted and stored) or unstructured (more free-form, less quantifiable).
Nearly every department in a company can utilize findings from big data analysis, but handling its clutter and noise can pose problems.
Big data can be collected from publicly shared comments on social networks and websites, voluntarily gathered from personal electronics and apps, through questionnaires, product purchases, and electronic check-ins.
Big data is most often stored in computer databases and is analyzed using software specifically designed to handle large, complex data sets.
How Big Data Works
Big data can be categorized as unstructured or structured. Structured data consists of information already managed by the organization in databases and spreadsheets; it is frequently numeric in nature. Unstructured data is information that is unorganized and does not fall into a predetermined model or format. It includes data gathered from social media sources, which help institutions gather information on customer needs.

What if I told you about this magical teaching practice that, done even once, produces large improvements in student final exam scores[1], helps narrow the grade gap between poorly prepped and highly prepped first year college students[2], and might even result in more positive course reviews[3],[4]? What if I also told you this magical teaching practice is something you already know how to do? What if I told you, the secret to increasing your students’ success and  overall satisfaction is……more TESTS!?
Okay…well to be fair, it’s a little more nuanced than that. While adding just one test to a class does indeed improve final exam scores, it turns out that more frequent, graded exercises in general improve learning outcomes for students [2],[5]. Even better – if these exercises are low stakes, they can improve learning outcomes without increasing student anxiety [4],[6].
We often view testing as an unpleasant but necessary way to assess student performance. It may be time for us to instead view testing as a useful teaching tool and to implement an assessment system that maximizes the potential learning benefits. In this post I will discuss the important known benefits of frequent, low stakes assessments as well as some practical tips for how to maximize these benefits without adding undue stress to your life or the lives of your students.

Benefit #1: “Thinking about thinking”
Testing can improve a student’s metacognition, or their ability to “think about thinking.” A good metacognitive thinker understands how their thought processes work and can pay attention to and change these processes [7]. A student with strong metacognitive skills can therefore more successfully monitor, evaluate, and improve their learning compared to students lacking these skills. Unfortunately, many students struggle with metacognition and must contend with “illusions of mastery” (or thinking they understand a subject better than they actually do).  Self-testing is a good way to prevent illusions of mastery, but many students do not incorporate self-testing into their studying, instead electing more passive modes of exam preparation such as rereading texts[8]. Incorporating more testing into the curriculum forces students into the position of making mistakes and receiving feedback, allowing them to frequently measure their learning in relation to expectations and adjust accordingly. Again, note that providing feedback is an essential part of this process.

Benefit #2: Practice Remembering
Testing can improve a student’s long term memory of information presented in class by forcing students to recall what they’ve learned through a cognitive process called active retrieval. Active retrieval strengthens neural pathways important for retrieving memories, allowing these memories to be more easily accessed in the future.
While any sort of retrieval practice is useful, it is most beneficial when it is effortful, spaced, and interleaved.  An example of effortful retrieval practice includes testing which forces students to provide the answers (i.e. Short answer and fill in the blank questions as opposed to multiple choice). More effortful retrieval also occurs with spaced and interleaved practice.
Spaced practice is testing that occurs after enough time has elapsed for some (but not complete) forgetting to occur (i.e. Present the information and then wait a couple months, days, or even just until the end of class to test students on it). Interleaved practice incorporates different but related topics and problem types, as opposed to having students practice and master one type at a time (e.g. cumulative testing where you mix problems from different units together). Interleaved practice can help students learn to focus on the underlying principles of problems and to discriminate between problem types, leading to more complex mental models and a deeper understanding of the relationships between ideas[6].

How to Implement More Assessments (Without Losing Your Mind)
So, all you have to do now is come up with a ton of quiz and test questions and free up a bunch of class time for assessments! Don’t forget you also need to grade all of these! After all, feedback is an important part of the process, and frequent (even low stakes) grading has the added benefits of enhancing student motivation, attentiveness, and attendance.I know what you busy teachers (ie. all of you) out there are thinking….“Your ”magical” teaching practice is starting to sound like a hugely effective pain in my butt.”
Don’t give up on me now though! There are some fairly simple ways to add more assessments to your curriculum. Furthermore, you should be able to do this sans student rebellion because these assessments are low-stakes. Frequent, low-stake assessments as opposed to infrequent, high-stakes assessments actually decrease student anxiety overall because no single test is a make it or break it event. In fact, several teachers have reported a large increase in positive student evaluations after restructuring their classes in this way[3],[4],[6]!

Below I lay out some tips for getting the most out of shifting your assessment practices while maintaining both your own and your students’ sanity:

1) Know that “effortful” testing is not always necessary
While effortful testing is best for retrieval practice, even basic, easily graded recognition tests such multiple choice questions still offer benefits, such as helping students remember basic (but important!) information[6],[9].

2) Create different assessment questions
You can also make assessments more effortful by creating questions that engage higher cognitive processes. Now you can sit back, relax, and indulge in one of my personal favorite pastimes (watching student brains explode) without the stressful grading!

3) Make use of educational technologies to ease your grading
For instance, clicker tests are a quick way to test students and allow you to provide feedback for the class all at once.

4) Make assessments into games
If your students need a morale boost, make a quiz into a trivia game and give winning groups candy. Some good old competition and Pavlovian conditioning may make students reassess their view of testing.

5) Assess participation
Doing something as simple as a participation grade will still provide students with incentive without overburdening them or yourself. For instance, this type of grading would work in conjunction with #3.

6) Keep graded assessments predictable
Making assessments predictable as opposed to utilizing pop quizzes helps students feel at ease.6 Furthermore, if they students KNOW an assessment is coming, they are more likely to study and pay attention.

7) Find ways to revisit old material in your assessments
Making assessments cumulative is an effective way to space out your review of material and has the added benefit of making problems interleaved and effortful, all of which maximize retrieval practice[6].

8) Have students reflect on mistakes
You can help students develop metacognitive skills by giving them opportunities to reflect upon and correct their mistakes on assessments. For instance, have students take a quiz and then discuss their answers/thinking with their classmates before receiving feedback. You can also give students opportunities to create keys to short answer questions and grade their own and several (anonymous) classmates’ answers. This will allow them to think through what makes an answer complete and effective.

9) Break large assessments into small ones
Instead of creating new assessments, break up large ones into multiple, lower-stakes assessments. For example, consider replacing big tests with several quizzes. Consider scaffolding large projects such as independent research projects and term papers. Ask for outlines, lists of references, graphs, etc. along the course of the semester before the final project is due. This might cause more work for you in the short term but can help prevent complete disasters at the end of the semester, which can be time consuming.

10) Utilize short daily or weekly quizzes
If you don’t want to adjust a big project/test or lose class time by adding time-consuming assessments, consider adding short daily or weekly quizzes. These grades can add up to equal one test grade. One could consider dropping the lowest score(s) but allowing no make ups to reduce logistical issues.
These are only a few of the many strategies one can use to transition to a frequent, low-stakes assessment system. What are your experiences with low stakes assessments? Have you made use of any which seem particularly effective in enhancing student learning?

Technology acceptance model

 
 


Based on the theory of reasoned Action, Davis ( 1986 ) developed the Technology Acceptance Model which deals more specifically with the prediction of the acceptability of an information system. The purpose of this model is to predict the acceptability of a tool and to identify the modifications which must be brought to the system in order to make it acceptable to users. This model suggests that the acceptability of an information system is determined by two main factors: perceived usefulness and perceived ease of use.
Perceived usefulness is defined as being the degree to which a person believes that the use of a system will improve his performance. Perceived ease of use refers to the degree to which a person believes that the use of a system will be effortless. Several factorial analyses demonstrated that perceived usefulness and perceived ease of use can be considered as two different dimensions (Hauser et Shugan, 1980 ; Larcker et Lessig, 1980 ; Swanson, 1987).
As demonstrated in the theory of reasoned Action, the Technology Acceptance Model postulates that the use of an information system is determined by the behavioral intention, but on the other hand, that the behavioral intention is determined by the person’s attitude towards the use of the system and also by his perception of its utility. According to Davis, the attitude of an individual is not the only factor that determines his use of a system, but is also based on the impact which it may have on his performance. Therefore, even if an employee does not welcome an information system, the probability that he will use it is high if he perceives that the system will improve his performance at work. Besides, the Technology Acceptance Model hypothesizes a direct link between perceived usefulness and perceived ease of use. With two systems offering the same features, a user will find more useful the one that he finds easier to use (Dillon and Morris, on 1996).

Speech perception is the process by which the sounds of language are heard, interpreted, and understood. The study of speech perception is closely linked to the fields of phonology and phonetics in linguistics and cognitive psychology and perception in psychology.  In the speech, perception seeks to understand how human listeners recognize speech sounds and use this information to understand spoken language. Speech perception research has applications in building computer systems that can recognize speech, in improving speech recognition for hearing- and language-impaired listeners, and in foreign-language teaching.
The process of perceiving speech begins at the level of the sound signal and the process of audition. (For a complete description of the process of the audition, After processing the initial auditory signal, speech sounds are further processed to extract acoustic cues and phonetic information. This speech information can then be used for higher-level language processes, such as word recognition.
