Tell a Story: Quantitative vs. Qualitative

Posted: Friday, October 1st, 2010

by Bonny Ralston, CSTA Middle School Director

Introduction

All science students need to practice the skill of detailed observation.  In describing an object or an observation, it’s important to cite as many details as possible.  In order to engage students to observe all details, it is necessary to have them practice what they should be looking for.  Shape, color, and amount are the most common observations.

This lab is used to introduce students to all kinds of observation.  Students will learn how to use observation by using similarities and differences, and quantitative and qualitative observations.

Materials

Part 1: Any type of small colorful toys like windups, or variety of colorful plants.

Part 2: Different types of natural items such as shells, pieces of wood, bones, or skulls.  If possible, include same types of shells like abalone for students to observe.  For each group: Chart showing qualitative vs. quantitative observations.

Part 3: Each student may bring in or select a natural item from the classroom.  For each table group: balances, rulers, (for small items) tools for density measurements.

Into: Hold up an item (toy or plant etc.).  Ask students to describe an observation like a color, a number, texture, etc.  Write down all answers on the board (qualitative).  Repeat with two or more trials until you feel all students have participated.  Hold the same items up or use a simple plant, and ask students to observe numbers of leaves, stems, etc. (quantitative).

Through: Have the group divide themselves in half.  Hand out an item to each group.  One group will determine as many quantifying observations and record on one-half of a folded paper.  The other group will find as many qualitative observations as possible then record on the second half of the paper.

If there’s time, the group can write a short story about the item using qualitative and quantitative observations.  The story can be about the life and times of the organism using a creative twist.  (Have students bring in their own items for next part on day two.)

Beyond: Now that the students have had a little practice, have them select an item from classroom specimens, or select the item from home.

On their own, students will complete observations for their item (as practiced previous day).  The goal is to use these observations to create a fictional story about the life and times of the item (organism, etc.).  Students should use creativity to write the story.  Students are allowed to research more about the organism they selected.  Students may also draw a close-up picture of the organism; use a jewelers’ loop (private eye) or magnifying glass.  The story or account should be a minimum of one page and no longer than three.

For English learners, you can have them draw a day in the life, like a comic book.  Encourage some vocabulary use to describe what’s happening in the picture.

Participate in Chemistry Education Research Study, Earn $500-800 Dollars!

Posted: Tuesday, May 9th, 2017

WestEd, a non-profit educational research agency, has been funded by the US Department of Education to test a new molecular modeling kit, Happy Atoms. Happy Atoms is an interactive chemistry learning experience that consists of a set of physical atoms that connect magnetically to form molecules, and an app that uses image recognition to identify the molecules that you create with the set. WestEd is conducting a study around the effectiveness of using Happy Atoms in the classroom, and we are looking for high school chemistry teachers in California to participate.

As part of the study, teachers will be randomly assigned to either the treatment group (who uses Happy Atoms) or the control group (who uses Happy Atoms at a later date). Teachers in the treatment group will be asked to use the Happy Atoms set in their classrooms for 5 lessons over the course of the fall 2017 semester. Students will complete pre- and post-assessments and surveys around their chemistry content knowledge and beliefs about learning chemistry. WestEd will provide access to all teacher materials, teacher training, and student materials needed to participate.

Participating teachers will receive a stipend of $500-800. You can read more information about the study here: https://www.surveymonkey.com/r/HappyAtoms

Please contact Rosanne Luu at rluu@wested.org or 650.381.6432 if you are interested in participating in this opportunity, or if you have any questions!

Lessons Learned from the NGSS Early Implementer Districts

Posted: Monday, May 8th, 2017

On March 31, 2017, Achieve released two documents examining some lessons learned from the California K-8 Early Implementation Initiative. The initiative began in August 2014 and was developed by the K-12 Alliance at WestEd, with close collaborative input on its design and objectives from the State Board of Education, the California Department of Education, and Achieve.

Eight (8) traditional school districts and two (2) charter management organizations were selected to participate in the initiative, becoming the first districts in California to implement the Next Generation Science Standards (NGSS). Those districts included Galt Joint Union Elementary, Kings Canyon Joint Unified, Lakeside Union, Oakland Unified, Palm Springs Unified, San Diego Unified, Tracy Joint Unified, Vista Unified, Aspire, and High Tech High.

To more closely examine some of the early successes and challenges experienced by the Early Implementer LEAs, Achieve interviewed nine of the ten participating districts and compiled that information into two resources, focusing primarily on professional learning and instructional materials.

Using Online Simulations to Support the NGSS in Middle School Classrooms

Posted: Monday, May 8th, 2017

by Lesley Gates, Loren Nikkel, and Kambria Eastham

Middle school teachers in Kings Canyon Unified School District (KCUSD), a CA NGSS K-8 Early Implementation Initiative district, have been diligently working on transitioning to the Next Generation Science Standards (NGSS) integrated model for middle school. This year, the teachers focused on building their own knowledge of the Science and Engineering Practices (SEPs). They have been gathering and sharing ideas at monthly collaborative meetings as to how to make sure their students are not just learning about science but that they are actually doing science in their classrooms. Students should be planning and carrying out investigations to gather data for analysis in order to construct explanations. This is best done through hands-on lab experiments. Experimental work is such an important part of the learning of science and education research shows that students learn better and retain more when they are active through inquiry, investigation, and application. A Framework for K-12 Science Education (2011) notes, “…learning about science and engineering involves integration of the knowledge of scientific explanations (i.e., content knowledge) and the practices needed to engage in scientific inquiry and engineering design. Thus the framework seeks to illustrate how knowledge and practice must be intertwined in designing learning experiences in K-12 Science Education” (pg. 11).

Many middle school teachers in KCUSD are facing challenges as they begin implementing these student-driven, inquiry-based NGSS science experiences in their classrooms. First, many of the middle school classrooms at our K-8 school sites are not designed as science labs. Learn More…

Celestial Highlights: May – July 2017

May Through July 2017 with Web Resources for the Solar Eclipse of August 21, 2017

by Robert C. Victor. Twilight sky maps by Robert D. Miller. Graphs of planet rising and setting times by Jeffrey L. Hunt.

In spring and summer 2017, Jupiter is the most prominent “star” in the evening sky, and Venus, even brighter, rules the morning. By mid-June, Saturn rises at a convenient evening hour, allowing both giant planets to be viewed well in early evening until Jupiter sinks low in late September. The Moon is always a crescent in its monthly encounters with Venus, but is full whenever it appears near Jupiter or Saturn in the eastern evening sky opposite the Sun. (In 2017, Full Moon is near Jupiter in April, Saturn in June.) At intervals of 27-28 days thereafter, the Moon appears at a progressively earlier phase at each pairing with the outer planet until its final conjunction, with Moon a thin crescent, low in the west at dusk. You’ll see many beautiful events by just following the Moon’s wanderings at dusk and dawn in the three months leading up to the solar eclipse. Learn More…
