Using mastering Learning method

Definition

Mastery learning proposes that all children can learn when provided with the appropriate learning conditions in the classroom. According to Benjamin Bloom, he said that the core idea of mastery learning is the length of time it takes a person to learn not how “bright” a person is, i.e., everyone can learn given the right circumstances

Discussion on Mastery Learning

The application of mastery learning is based on Benjamin Bloom’s Learning for Mastery model, with refinements made by Block. Mastery learning is predominantly a group-based, teacher-paced instructional approach, in which students learn by cooperating with their classmates. However, some mastery learning strategies require students to work independently, rather than with classmates
According to John B. Carroll, Benjamin Bloom, and Madeline Hunter they believe that mastery learning can be handled in a normal classroom. Another group has developed a comprehensive curriculum system for use in reorganized schools. Ref: Individually Prescribed Instruction (IPI–Learning Research and Development Center of the University of Pittsburgh) provides for organization of schools and classes to provide for more individualized instruction than is possible in most systems. Mastery learning theorists, especially Bloom (1971), contend that mastery learning techniques reduce the amount of time needed to achieve mastery.
Base on Benjamin Bloom experience he asked his students to “think out loud” while answering exam questions. He found that many students who could answer short-answer questions were befuddled by thought questions. They did not know how to solve problems not limited to math problem solving–including questions like, “Give the reasons which would have influenced a typical Virginia tobacco farmer to support the ratification of the Constitution of 1789, and the reasons which would have influenced him to oppose theratification.”
Bloom said, besides mastery of the material to be learned, mastery learning increases the attitude and interest of students (Fehlen, 1976). He and his students have conducted many empirical studies that demonstrate the effectiveness of mastery programs in a wide variety of circumstances (Levine, 1987). Bloom suggests that mastery learning procedures are likely to enhance learning outcomes in most all subject areas. However, he suggests that effects will be largest in mathematics and science since learning in these subject areas is generally more highly ordered and sequential (Guskey & Gates, 1986).
Meanwhile, Block (1971) states that students with minimal prior knowledge of material have higher achievement through mastery learning than with traditional methods of instruction.

How Mastery Learning Affects Education

  • Curriculum: Mastery learning does not focus on content, but on the process of mastering it. This type of learning works best with the traditional content-focused curriculum, one based on well-defined learning objectives organized into smaller, sequentially organized unit
  • Instruction: This strategy captures many of the elements of successful tutoring and the independent functionality seen in high-end students. In a mastery learning environment, the teacher directs a variety of group-based instructional techniques. The teacher also provides frequent and specific feedback by using diagnostic, formative tests, as well as regularly correcting mistakes students make along their learning path.
  • Assessment: Teachers evaluate students with criterion-referenced tests rather then norm-referenced tests. Mastery learning ensures numerous feedback loops, based on small units of well-defined, appropriately sequenced outcomes.

According to Notes from Benjamin Bloom lecture (ACSA, April, 1987) he said that there are 5 keys to sucsess:

a) Mastery Learning.
b) Home environment
c) Pre-requisite enhancement
d) Make reading automatic, beyond decoding
e) Emphasis on creativity, higher mental processes (upper levels of the Taxonomy of Educational Objectives, critical thinking, etc.)

Some advantages of learning by using mastery learning:
1. Students have prerequisite skills to move to next unit
2. Requires teachers to do task analysis, thereby becoming better prepared to teach the unit
3. Requires teachers to state objectives before designating activities
4. Can break cycle of failure (especially important for minority and disadvantaged students)

Adding more fun and variety to a classroom period

In a classroom period, a little variety and fun can add to a students learning experience. The concept is that a period of 40 minutes be viewed as containing different segments, not just the teacher teaching and students listening (as in traditional classroom). This allows teacher to use different approach to help students participate in the lesson, thus gaining better understanding of the lesson. For example, a teacher can use the following idea when teaching the mathematics lesson of ‘polygons’.

The first idea is to manage the block of time by divide it into smaller sections. The period in each block depends on what kind of activities that will be held. Therefore, teachers can use the time appropriately for study and for fun activities.

Then, the second idea is to ‘begin class with some reading’. One good approach in teaching mathematics is to motivate students throughout their studies to inspect mathematical shapes with respect to their roots or common usage (outside their mathematical context). To introduce the concept of ‘polygons’, a good book of shapes, which consists of basics shapes such that triangle, square, pyramid and rectangular. At the end of reading, students can differentiate the shapes of polygons. So the purpose of reading is to learn the basics of mathematical shapes. It is only take the first five minutes of the class period for these reading activities.

The third idea is to use a ‘repertoire of demonstration’. A demonstration is a powerful tool to help students see how a lesson has practical implications. For example, when teaching ‘polygons, teacher can demonstrate the students about the shapes of polygon by using the nearby material such that, cupboard, blackboard, eraser and desk. On the other hand, teacher can also join the students to explore the school surrounding in order to find more variety shapes of polygon.

The teacher should ready with inventory that suitable for teaching polygon such that model of pyramid. Thus, to attract the student attention, he teacher should be more creative by make a special appearance. For example, teachers can wear birthday party hat which is in shape of cone. While wearing the hat, the teacher can make a presentation contains important facts or concept of polygon. It is about five to ten minutes to ensure the students remember well about the topic.
The teachers can also use the idea of ‘play a game’. An appropriate game can bring benefits to students who play it, in terms of both enjoyment and interest they arouse and of the actual learning that results from the games. The following game can be used to fill ten minutes at the end of a lesson on ‘polygons’.

Equipments: Lego and diagram of ancient building

Method of play:

Try to build the ancient building such that pyramid and Stonehenge by combining the pieces of Lego. Student will provided with the diagram in order to help them.

Lastly, teachers can give their students some regular expression or quotation. More on to motivate the students and to set their minded that polygon is not a difficult subject. If all these seven steps follow, there is no more bored class. All it has the fun and active class.

How To increase effective listening in classroom

As a student we need to highlight few point as a guideline for effective listening in classroom. Firstly we need to concentrate on the message and focus to avoid mind drift. Concentrate only on the main point while looking for the hidden message. Second, determine the purpose of the message. There are three stage such as cautinous listening, skimming and scanning. Third is keep an open mind with respect the speaker’s viewpoint and aboid biases and prejudices. Besides that, we also need to provide feedback from verbal or nonverbal. Positive feedback will improve the communication addition paraphrasing lets the speaker know we understood the message. While listening we need to minimize note taking, talk or interrupt because it may interfere with the listening process.
