Scholar Academic Social Efficiency Learner Centered Social Reconstruction

M.S. Schiro (2013)

Over centuries our culture has accumulated important knowledge that has been organized into the academic disciplines found in universities.

The aim of education is to get children to acquire this body of accumulated knowledge, i.e., the various academic disciplines.

Education involves making youth members of a discipline by first moving them into it as students and then moving them from the bottom of hierarchy towards its top.

• Social efficiency

The purpose of schooling is to efficiently meet the needs of society by training youth to function as future mature contributing members of society.

• Social efficiency

Train youth in the skills and procedures they will need in the workplace and at home to live productive lives and perpetuate the functioning of society.

• Social efficiency

Youth achieve an education by learning to perform the functions necessary for social productivity.

• Learner centered

Focuses on the needs and the concerns of the individuals.

• Learner centered

The goal of education is the growth of individuals, each in harmony with his or her own unique intellectual, social, emotional and physical attributes.

• Social reconstruction

Come from a social perspective. Awareness of societal problems, e.g.,

racial, gender, social and economic inequalities.

• Social reconstruction

The purpose of education is to facilitate the construction of a new and more just society that offers maximum satisfaction of its members.

• Enacted curriculum

Perceived part (by the teachers)

• Qualitative feedback by teachers

Is there a real need for changes in syllabus? If so, why?

• Qualitative feedback by teachers

I think the syllabus should change according to the changing needs. Beauty, suitability, relevance and applicability are some parameters for consideration when deciding on the contents of the syllabus.

• Qualitative feedback by teachers

At the level you are operating, what are some of the benefits you reap, and what are the challenges you face whenever there is a change of syllabus?

• Qualitative feedback by teachers

Teaching the new H2 Further Mathematics syllabus has given me the opportunity to pick up topics like Conics and Numerical Methods.

Whenever the syllabus changes there is often a necessity to learn new topics, let alone teach them. I have to pick up Conics from scratch as I have never learned it with such depth myself as a student.

• Qualitative feedback by teachers

Describe the changes in the learning outcomes of the students over these years of changes in the syllabus.

• Qualitative feedback by teachers

The changes made to the syllabus over the last few years have been trying to make the learning of mathematics more relevant to the student by relating it to the real-world contexts. The implementation of Learning Experiences and the introduction of Application Questions in the examination aim to achieve this goal.

• Qualitative feedback by teachers

I do agree that mathematics should be seen as an effective tool in solving real-world problems but I also do not discount the fact that studying mathematics should be an end itself. That is, mathematics should be pursued regardless of whether it has potential for applications. But it almost always turns out that some obscure piece of pure mathematics holds the key to the answer of some deep questions in science.

• Qualitative feedback by teachers

Sum up your experience/opinions concerning the change in A-level mathematics syllabus over these 20 years.

• Qualitative feedback by teachers

I think the H2 Math syllabus should provide opportunities for students to think logically and articulate mathematically. One area where students can develop these good qualities is Proofs. I am actually saddened that Mathematical Induction (MI) has been removed from the H2 Math syllabus. MI is an important tool in proving mathematical statements.

• Qualitative feedback by teachers

Students can also appreciate the beauty of this technique and its logical foundation. Its a beautiful piece of mathematics. I feel that that some of the proofs in the current H2 Math syllabus are not rigorous enough. For example, to proof that a function is 1-1, one uses the horizontal line test which is incorrect.

• Qualitative feedback from teachers

Mechanics is another subject which in my opinion lends itself perfectly to mathematical modelling and applications in real-world contexts. It also has cross-disciplinary interaction with Physics.

• Qualitative feedback from teachers

I strongly maintain that traditional pure mathematics topics like Group Theory should be brought back to the A level FM syllabus to let students have a taste of handling mathematical proofs and understanding what a mathematical structure is. This idea of structure in mathematics is an important one and permeates almost all branches of mathematics Group structure, Measure Spaces, Normed Spaces, and Topological Spaces etc. are all mathematical structures.

• Qualitative feedback from teachers

I remember the Math B and Further Math B syllabus I did as a student have given me a strong foundation to study mathematics in the university. I cant really say the same about our current syllabus.

• Enacted curriculum

Operational part

The content actually delivered during instruction (i.e., instructional content), as well as how it is taught (i.e., instructional practices).

Typically, the content targets are based on the intended curriculum.

• Learning experiences

Model and apply mathematics to a range of real-world problems (e.g., using exponential growth model to model population growth) afforded by the concepts and models in the syllabus;

• Learning experiences

Make connections between ideas in different topics and between the abstract mathematics and the real-world applications and examples; and

• Learning experiences

Use ICT tools to investigate, form conjecture and explore mathematical concepts (e.g., properties of graphs and their relationship with the algebraic expressions that describe the graph).

• Constructivist classroom

A blend of pedagogies

Greater student participation, collaboration and discussion

Greater dialogue between teachers and peers

• Constructivist classroom Students take on a more active role in

learning, and construct new understandings and knowledge.

Teachers role is to facilitate the learning process through more in-depth dialogue and questioning, and guide students to build on their prior knowledge, and provide them with opportunities for more ownership and active engagement during learning

• Findings and implications

The school takes a larger share of responsibility in terms of curriculum decision-making!

• Findings and implications

Changes in A-level math syllabus can be caused by or associated to different ideological orientation

Changes in A-level math syllabus arise from decision-making in curriculum; short- vs long-term, and general vs specific

• Findings and implications

Changes in A-level math syllabus manifest themselves in different domains: Intended Enacted Perceived & Learned Assessed

• Some research questions At what levels are the changes in the A level

mathematics syllabus initiated and being operated?

Do the usual orientations, i.e., curriculum ideologies (academic scholar, social efficiency, student-centered, social reformation) account for these changes? Any one which is dominant, or should it be a hybrid?

• Some research questions

Is the generic framework offered proposed by Eisner (2007) rigorous enough to account for the changes specific to the context of A level mathematics in Singapore?

Are there anything peculiar to A level mathematics teaching in the schools that are different from those at Primary and Secondary Schools?

• Some research questions

How best can the schools top management, its middle leadership and its teachers (and perhaps its students) best make out of these changes, cope with them, and even thrive and benefit from them?

• Some research questions

To what extent and how well all the policy elements in the educational system working together to guide instruction and, ultimately, facilitate and enhance student learning?

In other words, how well do the different forms of curriculum for A-level Mathematics align?

• Some research questions

How do the theoretical considerations presented here (e.g., ideological orientations, and Eisners model) help the (a) policy maker, (b) school leader, (b) middle leader, and (c) classroom teacher achieve a better alignment between the different forms of the A-level math curricula?

• Some research questions

Will there be a new world-order in which one day we shall be applying social reconstruction to our education system? Or are we already doing that now?
