Mari skor 50/50

[FORMULA 50/50]

KERTAS 3

SPM 2014

Bio di hatiku …………

QUESTION 1: STRUCTURE

(a) FORMULAE 1: Teknik baca soalan

Baca stem soalan GARIS & TANDA

Tulis semula MV [cMV, aMV], RV [cRV, aRV] & CV

JANGAN jawab soalan selagi tidak mengenalpasti variable

(b) FORMULAE 2: Mengukur menggunakan nombor

Read/Measure/count + decimal point (jika perlu) + Unit

(c) FORMULAE 3: Observation

TIRU tajuk jadual* = MV + CRV dan bina ayat

Jangan guna perkataan sendiri

Ada unit

No need to compare

*jika keputusan dalam bentuk jadual

Pilih yang paling tinggi & paling rendah

(d) FORMULAE 4: Inference

compare ..... higher/lower

give reason…. because + ARV

teori mengapa fenomena tersebut berlaku

Boleh kaitkan antara aMV dan aRV

(e) FORMULAE 5: Variables

Variable Operating the variables

Manipulated variable:

TIRU tajuk jadual

@ refer Formula 1

TIRU kaedah dari stem soalan.

[do ….. difference MV ….. ]

Responding variables:

TIRU tajuk jadual

@ refer Formula 1

Count/measure/observe/calculate and record .........

[Do ‘something’ to get RV by using ‘something’] =

teknik

Controlled variable:

refer Formula 1

..... (same) ........ (throughout experiment)/in each

repeating experiment

(f) FORMULA 6: Hypothesis

MV + RV + relationship (refer objektif eksperiment)

Guna ‘compare’:

o jika MV berbentuk kualitatif//berbeza

o data kurang dari 3 dan tidak ‘direct proportional’

Guna ‘4 the’ = The ... the (MV)....the.....the (RV)...

o jika MV adalah kuantitatif/ banyak nilai

o jika keputusan adalah lebih dari 3, berbentuk kuantitatif dan ‘direct proportional’

(g) FORMULA 7: Bina jadual/melukis

Bina jadual yang sesuai: row & column

Ada tajuk [terdiri dari MV dan RV]

Unit

(h) FORMULA 8: Melukis graf

(Axis X = MV + unit)

(Axis Y = RV + unit )

Pindah data/points (P) - guna ‘X’, jangan guna titik/dot

All points correctly plotted

Melukis garis graf (S)

menyentuh semua titik

bentuk licin.

JANGAN ada lajakan/penambahan garis graf.

Refer: Graf bar & histogram

(i) FORMULAE 9: Interpreting Data [UPSR]

Refer to data table/graph

Bina ayat dengan menyebut

- Unit/Phases

- Shape of the graph

- Beri Reason/ARV (jika perlu)

(j) FORMULA 10: Operational Definition

Biasanya berkaitan dengan ARV

o ARV = Classification + CRV + MV + CV

(k) FORMULA 11: Predicting

State the referent value

State more/less than .....(refer to data table)

Give your suggested value

Reason

(l) FORMULA 12: Classification

Bina jadual

Kenalpasti tajuk jadual

Masukkan data mengikut pengelasan yang betul.

QUESTION 2: ESSAY

(a) FORMULA 13: Planning*

TIRU langkah ‘planning’ yang disenaraikan

Kira semula bilang langkah supaya tidak tertinggal

(b) FORMULA 14: Objective

To ..... (MV +RV)

(c) FORMULA 15: Problem statement

What/Is/do/does/...... MV +RV+ ?

Untuk comparison elak menggunakan ‘MV…. effect by ….RV’

Untuk direct propotioanal boleh guna ‘MV…. effect by ….RV’

(d) FORMULA 16: Hypothesis

Direct propotional: guna ayat ‘4 the’

Banding: Jika MV hanya 2 atau 3 sahaja

Specific

(e) FORMULA 17: Variables

Manipulated variable: Faktor yang diubah

Responding variable : keputusan yang diperolehi

Fixed variable: faktor yang dikekalkan, tidak berubah sepanjang eksperiment

(f) FORMULA 18: Apparatus/materials

MV ....... apparatus /materials

ARV....... apparatus /materials

CV....... apparatus /materials

(g) FORMULA 19: Technique

Do something ................ eg. read, count, observe

to get (CRV) .......... (result) eg. value, number, color change

by using something ........ (a device/apparatus) eg. weighing scale, ruler, microscope

Measure & record Time

Volume

Mass …. by using …(apparatus)

Temperature

Length

Count & record Number

Observe & record Colour change

Shape

Calculate & record Energy value

Vitamin C content ... by using …(formulae)

Rate of ……

Kuadrat sampling, CRRC

PROCEDUR (K1 – K7)

KI : use & (purposes) of apparatus & materials ...

K2: conduct manipulated variable .......

K3: conduct responding variable .....

K4: conduct constsnt variable .......

K5: tabulate & record data ......

K6: formulae (spm04) .....

K7: precaution & safety precaution

Safety precaution + reason

Experiment precaution + reason

(h) FORMULA 20: K1 [using apparatus & materials]

(do) ..... (using ....)

(i) FORMULA 21: K2 [MV]

Repeat the step ..... by using [other MV]

(j) FORMULA 22: K3 [RV]

= technique [FORMULA 19]

[Do something to get CRV by using something]

Count/measure/observe and record ...........

(k) FORMULA 23: K4 [CV]

..... (same) ........

throughout experiment/in each repeating exp

CV should be emphasize clearly in procedure

(l) FORMULA 24: K5 [komunikasi data]

(m) FORMULA 25: K6 [formulae – jika ada]

.... dikira mengikut formula berikut ......

Tuliskan formula berkenaan

(n) FORMULA 26: K7 [precaution]

langkah berkaitan keselamatan

langkah ketepatan keputusan

Nyatakan langkah yang dicadangkan + alasan

Refer RV (untuk tujuan mendapat keputusan yang lebih tepat)

(o) FORMULA 27: Result

Hanya jadual kosong dan tajuk sahaja

Pastikan ada unit

JANGAN masukkan data

(p) FORMULA 28: Conclusion

Rujuk ayat hypothesis

(q) FORMULA 29: TEKNIK MENGULANGKAJI

Anda dinasihatkan membuat latihan kertas 3

berasaskan KEMAHIRAN

CONTOH:

Cuba aplikasi FORMULA 10 untuk menjawab soalan berkaitan

operational definition sahaja dengan melalui beberapa set latihan

(secara horizontal).

……………………………………………………………………………………………………………….

(r) FORMULA 30: PERUBAHAN TERKINI

Soalan SPM kemungkinan akan mengalami beberapa perubahan dari

tahun ke tahun, terutama dalam ‘pattern’ soalan dan peraturan

permarkahan.

Walaubagaimanapun corak pemikiran saintifik seperti yang

diformulakan adalah tetap sama dan tidak berubah.

Contoh:

Dalam agihan markah ‘complimentary mark’

SPM 2003

o Complimentary marks

complete planning format (1 mark)*

data table (mark)

SPM 2004

o Complimentary marks

formulae (1 mark)

data table (mark)

SPM 2005

o Complimentary marks

technique (1 mark)

title of data table (1 mark)

o Relationship between space & time – not included.

So – variable (statement) – given 6 marks

SPM

2011

Planning: ..................... [tiada markah]

1. Problem Statement [3]

2. Objective ………….. dimansuhkan

3. Hypothesis[3]

4. Variables statements *

5. Apparatus & Materials[3]

6. Technique

7. Procedures [3]

8. Data communication/table *

*Complementary mark: 2

Time + height/length/distance etc cannot consider as CV,

included in formulae to calculate rate of …

CV should be emphasize clearly in procedure (use ‘it own

specific’sentences)

Manjadda Wajada Semoga mendapat rahmat, keberkatan & kecemerlangan

Amin.
