Authentic Assessments

LEARNING SCENARIO

REDUCE THE DISTURBANCE FROM NOISE

A science class was given an investigation project to determine how to reduce the noise coming from adjacent apartments. The learning was intended around how to create a sound/noise proof living space. The student knew various aspects of waves, how they travel, the various wave phenomenon like interference, reflection and Doppler effect. The next section discusses how this can be solved using an authentic assessment around problem based learning.

COMPLEX LEARNING METHOD

PROBLEM BASED LEARNING(PBL)

The investigation on creating a sound proof living space using a problem based learning.

Some learning around PBL...

PBL is a student-centered, inquiry-based instructional model in which learners engage with an authentic, ill-structured problem that requires further research (Jonassen & Hung, 2008).

Students identify gaps in their knowledge, conduct research, and apply their learning to develop solutions and present their findings (Barrows, 1996).

Through collaboration and inquiry, students can cultivate problem solving (Norman & Schmidt, 1992), metacognitive skills (Gijbels et al., 2005), engagement in learning (Dochy et al., 2003), and intrinsic motivation.

LEARNING SCENARIO AND PBL

HOW TO APPROACH THE LEARNING SCENARIO THROUGH PBL..

Here are the steps on how the learning scenario would be dealt with a PBL approach.

1. Defining the problem.

Creating a sound proof wall so that neighbors are not worried about sound coming from the adjacent apartments.

2.Explore what they know about the problem.

For example, reading about sound, its properties. How waves propagate and what causes the noise to be heard.

3. Determine what needs to be learned and what information acquired.

Here the student can research on speed of sound waves as they travel through materials, what property of material causes them to slow down. Research will also include how sound waves undergo dampening, constructive and destructive interference.

4. Evaluate ways to solve the problem.

Student identify possible materials that can be used as soundproof barriers during construction. They form groups and and discuss issues and present the findings.

5. Solve the problem.

Identify the best sound proofing materials that can be used along with construction material. Conduct a test to prove that the material slows down the sound wave.

6. Report the findings and conclude.

Make a report on how each material slowed down the sound wave while passing through it. Based on the finding identify the best sound proof material that can be used in construction materials.
