Illustration

• We all solve problemson a daily basis,in academic situations,at work, andin our day-to-day lives.

Illustration (cont.)

• Some of the problems that are typically faced by students include:– Putting together an argument for an essay– Debugging a computer program– Dealing with an awkward customer when working

part-time in a shop or restaurant



– Thinking about how you are going to manage your budget to keep you going until the end of term

– Working out why your printer won’t respond– Developing a strategy to reach the next level of a

computer game.

Some definitions

• Problem-solving is a mental process that involves discovering, analyzing and solving problems. The ultimate goal of problem-solving is to overcome obstacles and find a solution that best resolves the issue.


Kendra Cherry, “What Is Problem-Solving?”, About.com Pyschology, URI http://psychology.about.com/od/problemsolving/f/problem-solving-steps.htm [20130719.0208].

Some definitions (cont.)

• Problem-solving consists of using generic or ad hoc methods, in an orderly manner, for finding solutions to problems. Some of the problem-solving techniques developed and used in artificial intelligence, computer science, engineering, mathematics, medicine, etc. are related to mental problem-solving techniques studied in psychology.

Two types of approach

• There are two types of approach:– rational approach,– organic approach.


Carter McNamara, “Problem Solving and Decision Making (Solving Problems and Making Decisions)”, Free Management Library, URI http:// management help.org/personalproductivity /problem-solving.htm[20130719.0227].

Rational approach

• A person with rational approach often prefers using a comprehensive and logical approach similar to the guidelines. For example, the rational approach is often used when addressing large, complex matters in strategic planning.

• There are structured guidelines in this type of approach.


Rational approach (cont.)

• A major advantage of this approach is that it gives a strong sense of order in an otherwise chaotic situation and provides a common frame of reference from which people can communicate in the situation.

• A major disadvantage of this approach is that it can take a long time to finish. Some people might argue, too, that the world is much too chaotic for the rational approach to be useful.


Organic approach

• With organic approach, some people assert that the dynamics of people are not nearly so mechanistic as to be improved by solving one problem after another. Often, the quality of life comes from how one handles being “on the road” itself, rather than the “arriving at the destination.”


Organic approach (cont.)

• The quality comes from the ongoing process of trying, rather than from having fixed a lot of problems. For many people it is an approach to organizational consulting.

• The guidelines are based on people experien-ces.



• A major advantage of the organic approach is that it is highly adaptable to understanding and explaining the chaotic changes that occur in everyday life.

• The major disadvantage is that the approach often provides no clear frame of reference around which people can communicate, feel comfortable and measure progress toward solutions to problems.



• From Jung, Carl, Psychological Types (Pantheon Books, 1923):“All the greatest and most important problems in life are fundamentally insoluble… They can never be solved, but only outgrown. This “outgrowing” proves on further investigation to require a new level of consciousness.



Some higher or wider interest appeared on the horizon and through this broadening of outlook, the insoluble lost its urgency. It was not solved logically in its own terms, but faded when confronted with a new and stronger life urge.”


Stages of problem solving

• Problem Identification• Structuring the Problem• Looking for Possible Solutions• Making a Decision• Implementation• Monitoring/Seeking Feedback


“Problem Solving”, SkillsYouNeed – Helping You Develop Life Skills, URI http://www.skillsyouneed.com/ips/problem-solving.html [20130719.0306].

Stages of problem solving (cont.)

• .. or IDEAL:– Identify the problem– Define the problem– Examine the options– Act on plan– Look at the

consequences

Strategies

• Abstraction: solving the problem in a model of the system before applying it to the real system.

• Analogy: using a solution that solves an analogous problem.


Wikipedia contributors, “Problem solving”, Wikipedia, The Free Encyclopedia, 25 June 2013, 06:19 UTC, oldid:561473281 [20130719.0212].

Strategies (cont.)

• Brainstorming: (especially among groups of people) suggesting a large number of soluti-ons or ideas and combining and developing them until an optimum solution is found.

• Divide and conquer: breaking down a large, complex problem into smaller, solvable problems.


Strategies (cont.)

• Hypothesis testing: assuming a possible explanation to the problem and trying to prove (or, in some contexts, disprove) the assumption.

• Lateral thinking: approaching solutions indi-rectly and creatively.

• Means-ends analysis: choosing an action at each step to move closer to the goal.


Strategies (cont.)

• Method of focal objects: synthesizing seem-ingly non-matching characteristics of different objects into something new.

• Morphological analysis: assessing the output and interactions of an entire system.

• Proof: try to prove that the problem cannot be solved. The point where the proof fails will be the starting point for solving it.


Strategies (cont.)

• Reduction: transforming the problem into an-other problem for which solutions exist.

• Research: employing existing ideas or adapt-ing existing solutions to similar problems.

• Root cause analysis: identifying the cause of a problem.

• Trial-and-error: testing possible solutions until the right one is found.


Kerja kelompok

• Buat kelompok terdiri dari lima orang.• Pikirkan contoh-contoh permasalahan dan

ajukan (waktu 5 menit).• Diskusikan contoh-contoh permasalahan yang

diajukan dan telah disepakati sebagai contoh menggunakan pendekatan rasional (20 menit).

• Presentasikan problem solving dari perma-salahan tersebut (10-15 menit/kelompok)


Kerja kelompok (cont.)

• Saat presentasi (10-15 menit):– perkenalkan nama seluruh anggota (1 menit),– bacakan topik dan alasannya (1-2 menit),– sebutkan strategi yang digunakan (1-2 menit),– terangkan dengan singkat tahapan problem

solving dalam IDEAL (5 menit),– dengarkan dan jawab pertanyaan (5 menit).


Contoh presentasi 1

• Perkenalkan kami adalah ..• Topik yang akan dibahasa adalah Konsep Gaya

Sentripetal dalam Gerak Melingkar.• Bagaimana menjelaskan gerak roller-coaster

merupakan alasannya.• Strategi: analogi menggunakan hukum II

Newton


Contoh presentasi 1 (cont.)

• I: Apa contoh-contoh gerak melingkar? Batasan apa yang selalu ada saat benda bergerak melingkar? Bagaimana menjelaskannya?

• D: Perlu adanya suatu cara yang sama untuk membahasa semua gerak melingkar.

• E: Lintasan selalu berbentuk lingkaran dan benda dibelokkan menuju pusat lingkaran.



• A: Ungkapkan adanya gaya yang selalu berarah ke pusat lintasan berbentuk lingkaran. Gaya ini merupakan total gaya yang bekerja gaya sentripetal.

• L: Bahas contoh-contoh kasus dan uji apakah konsep yang diajukan melingkupi semua kasus tersebut.


Contoh presentasi 2

• Perkenalkan kami adalah ..• Topik yang akan dibahasa adalah Tidak

Mengerti Penjelasan Dosen.• Alasan: malas kuliah karena hampir setiap

kuliah tidak jelas.• Strategi: uji hipotesis – masalah komunikasi



• I: Malas kuliah.• D: Tidak dapat mencatat dengan baik. Tulisan

terlalu kecil. Kurang dapat mengikuti kecepatan mengajar dosen.

• E: Duduk selalu di belakang. Mata cepat lelah karena terlalu jauh mengubah fokus antara catatan dan papan tulis. Tidak belajar sebelumnya.



• A: Datang lebih pagi dan duduk di baris lebih depan atau terdepan. Belajar lebih dulu sehingga hanya perlu mencatat hal-hal yang belum diketahui. Karena telah membaca buku teks, cukup menandai bagian-bagian tersebut.

• L: Kuliah jadi menyenangkan. Ingin lebih pagi datang kuliah. Merasa jam kuliah berlangsung terlalu cepat.
