SCIENCE PROCESS SKILL

The science process skills are the tools that students use to investigate the world around them and to construct science

concepts.

Conny (1987 ) states the basic abilities in question are observed , counting , measuring , classifying , searching for the

relationship of space and time , make hypotheses , plan for research or experimentation , verbal control , interpreting data , making

tentative conclusions , predict , apply , and communicate .

Here we suggest one possible interpretation of seven of the process skills of science (Harlen and Jelly , 1997) :

1 .Observing : watching carefully , taking notes , comparing and contrasting

2 .Questioning : asking questions about observations ; asking questions that can lead to investigations

3 .Hypothesizing : Explanations providing consistent with available observations

4 .Predicting : suggesting an event in the future , based on observations

5 .Investigating : planning , conducting, measuring , gathering the data , controlling variables

6 .Interpreting : synthesizing , drawing Conclusions , seeing patterns

7 .Communicating : informing others in a variety of means : oral , written , representational

HOW TO DEVELOP SCIENCE PROCESS SKILL ITEM

1 . General characteristics

a. Should not be burdened with the concept , the concept involved should be familiar to students ( close to everyday life )

b . Contains a large amount of information that must be processed by the student ; may include images , charts , graphs , tables or

description or the original object .

c . Aspects are measured must be clear and contain only one type of aspect .

d .Should be displayed to help bring the image of the object.

2 . Special characteristics

a. Observation : Objects / events that actually

b. Classification :There should be an opportunity to explore / discover similarities and differences , or given specific

criteria for grouping or a specified number of groups to be formed .

c. Interpretation : Should present some data to show patterns

d. Prediction : It should be clear pattern or trend to submit allegations or forecast

e. Infering

f. Communication : There must be a

certain form of representation to be transformed into other forms of presentation , for example, in narrative form to the shape

of the chart or table form into the form of graphs

EXAMPLE OF THE QUESTION WITH SCIENCE PROCESS SKILL ASPECT

No Aspect Example of question Information1. Observing 1. Listing the similarities and differences of a cube of ice and a ball of ice

2. Look at the picture below!

Check it carefully. What you can say about picture above?

Using the senses and appropriate tools to gather information about an object, event,or phenomenon.

SUBSKILLS include collecting evidence, identifying similarities and differences, classifying, measuring, and identifying relevant observations.

2 Classifying 1. In the below are the animals.

A Tiger A Goat A CamelAn Elephant

Based on the picture above. Classify it based on their types food...a. Tiger – Elephants – Bearb. Horsea – camel – bearc. Goat – camel – tigerd. Bear – camel – elephante. Goat – horsea – elephant

3 Predicting PredictingIn one ecosystem there are animals such as rabbit, snake, zebra and tiger. In that ecosystem there is a lot of grass and plants. If the grass and plant are destroyed and no more grass and plants again, predict the condition that will occur...a. The rabbit will be die toob. The snake and rabbit will be diec. The rabbit and zebra will be died. Snake and tiger will be diee. All of animals will be die

4 Planning and Investigating

What do you do to determine the effect of salt and sugar to ice cube?

melting rates in order to determine if one melts faster than the other.) data. Planningincludes devising a way to test a hypothesis. NOTE: Planning is not always formal.SUBSKILLS include identifying and controlling variables, and using measuring instruments.

6 Interpreting 1. Lets do an experiment!

After observing the melting rates of an ice cube sprinkled with salt and one without salt, what your conclusion?

Considering evidence, evaluating, and drawing a conclusion by assessing the data:In other words, answering the question, ”What do your findings tell you?” Finding apattern or other meaning in a collection of data.

SUBSKILLS include interpreting data statistically, identifying human mistakes andexperimental errors, evaluating a hypothesis based on the data, and recommending

further testing where necessary.
