5 characteristics of an effective science teacher – from a researcher who trains them

Effective science teachers use everyday natural events to get students to explore their world. Here’s how they do it, according to an expert who prepares elementary school science teachers.

Rather than have students memorize definitions and facts about a science topic such as light, an effective first grade teacher today would have students investigate various types of objects under sunlight and flashlight. Students would collect evidence to understand how light helps them see, and they’d experiment with different materials to understand how and why shadows are made.

This shift is a result of the Next Generation Science Standards, which aim to define a uniform vision for K-12 science education across the country. Introduced in 2013, the standards move away from emphasizing scientific vocabulary and facts recorded in textbooks to using real-world phenomena to explore and explain the natural world. These phenomena engage students in a set of science and engineering practices, or SEPs. Over 40 states have adopted the Next Generation standards or some version of them.

Despite the wide adoption of these standards, the current status of elementary school science education is concerning. The nation’s report card shows that many students in grades K-5 do not get quality science instruction. The situation is worse in high-poverty school districts. The majority of instructional time in elementary school grades is often dedicated to math and language arts, with science on the back burner.

As a science education researcher and a teacher educator, my goal is to help prepare the next generation of science teachers. Here are five attributes of an effective elementary school science teacher that align with the new standards.

1. Nurtures student curiosity

Kids are curious by nature. Science teachers should use relevant everyday events as a basis of science instruction that fosters interest and curiosity. This approach encourages students to take a more active role in figuring out how natural events work instead of being taught those lessons by an instructor.

For instance, in this video, a teacher poses an interesting query to students: How did a water puddle disappear over time? During a subsequent experiment, students used thermometers to measure the temperature of a water puddle outside at different times of the day. They used the data to make connections between temperature changes and the shrinking size of the puddle and delve into the reasoning behind it.

In this case, the teacher involved students in scientific practices and used an everyday occurrence to teach key scientific concepts such as sunlight, energy and energy transfer.

2. Encourages scientific thinking

Effective science teachers involve students in making sense of natural events and the science ideas underlying them. In other words, they actively engage students in wondering and figuring out science phenomena around them and how they happen. They help students develop exploratory questions and hypotheses to explain such events, and encourage them to test and refine their explanations based on scientific evidence.

For example, when a first grade classroom was learning about how day and night happen, students illustrated their own understanding of the phenomena – using a scientific practice called modeling. As they learned more and more, they kept revising their drawings. They also collected long-term data to understand the repeating patterns of day and night.

Teachers should also ensure that all students participate in making sense of science phenomena in their classrooms.

To share their ideas about a science phenomenon, students often rely on their personal experiences and native languages from their homes and communities. For instance, a student from an agricultural community might have particular knowledge about plant growth and unique local language to describe it. An effective science teacher provides opportunities to build on such native experiences and local knowledge in their science classrooms.

3. Develops scientific literacy

Teachers who plan lessons according to the current standards aim to develop scientifically literate young citizens who can identify, evaluate and understand scientific arguments underlying local and global issues.

They also use socioscientific issues in their instruction. Socioscientific issues are local or global phenomena that can be explained by science and signify social and political problems. For example, students might make sense of the scientific information underlying the current COVID-19 crisis and make arguments for how and why vaccination is important for their communities. Other examples of socioscientific issues are climate change, genetic engineering and pollution from oil spills.

4. Integrates science with other subjects

Teaching science with an interdisciplinary approach – that is to say, using math, technology, language arts and social studies to make sense of science phenomena – can lead to rich and rigorous learning experiences.

For example, teachers can integrate math by having students create visual charts and graphs to explain their experimental or observation data. Technology integration in the form of games and simulations in science classrooms can help students picture complex science ideas. Incorporating reading and comprehension strategies in science can bolster students’ ability to read critically for scientific ideas and evidence.

5. Uses classroom assessments to support student learning

A science teacher who is interested in students’ ideas will design and use classroom-based assessments that reveal students’ science thinking. They do not use closed-ended assessments that require yes or no answers, textbook-style definitions or lists of scientific facts. Instead, they use open-ended, phenomenon-based assessments that give students a chance to show their understanding.

For example, a fifth grade assessment presents students with a story of an Australian ecosystem and prompts them to use modeling to explain relationships between different components of the ecosystem. Such an assessment encourages students to explain how a process happens instead of recalling information.

Effective science teachers do not evaluate students’ responses for right and wrong answers. They interpret and evaluate students’ scientific explanations to understand strengths and gaps in their learning and use this information to adapt future instruction.

Teachers who are prepared to implement these five evidence-based practices can potentially involve all students in their classroom in meaningful science learning.

Key shipping company files for Chapter 11 bankruptcy

The Illinois-based general freight trucking company filed for Chapter 11 bankruptcy to reorganize.

Published

on

The U.S. trucking industry has had a difficult beginning of the year for 2024 with several logistics companies filing for bankruptcy to seek either a Chapter 7 liquidation or Chapter 11 reorganization.

The Covid-19 pandemic caused a lot of supply chain issues for logistics companies and also created a shortage of truck drivers as many left the business for other occupations. Shipping companies, in the meantime, have had extreme difficulty recruiting new drivers for thousands of unfilled jobs.

Freight forwarder company Boateng Logistics joined a growing list of shipping companies that permanently shuttered their businesses as the firm on Feb. 22 filed for Chapter 7 bankruptcy with plans to liquidate.

The Carlsbad, Calif., logistics company filed its petition in the U.S. Bankruptcy Court for the Southern District of California listing assets up to $50,000 and and $1 million to $10 million in liabilities. Court papers said it owed millions of dollars in liabilities to trucking, logistics and factoring companies. The company filed bankruptcy before any creditors could take legal action.

Lawsuits force companies to liquidate in bankruptcy

Lawsuits, however, can force companies to file bankruptcy, which was the case for J.J. & Sons Logistics of Clint, Texas, which on Jan. 22 filed for Chapter 7 liquidation in the U.S. Bankruptcy Court for the Western District of Texas. The company filed bankruptcy four days before the scheduled start of a trial for a wrongful death lawsuit filed by the family of a former company truck driver who had died from drowning in 2016.

California-based logistics company Wise Choice Trans Corp. shut down operations and filed for Chapter 7 liquidation on Jan. 4 in the U.S. Bankruptcy Court for the Northern District of California, listing $1 million to $10 million in assets and liabilities.

The Hayward, Calif., third-party logistics company, founded in 2009, provided final mile, less-than-truckload and full truckload services, as well as warehouse and fulfillment services in the San Francisco Bay Area.

The Chapter 7 filing also implemented an automatic stay against all legal proceedings, as the company listed its involvement in four legal actions that were ongoing or concluded. Court papers reportedly did not list amounts for damages.

In some cases, debtors don't have to take a drastic action, such as a liquidation, and can instead file a Chapter 11 reorganization.

Nationwide Cargo seeks to reorganize its business

Nationwide Cargo Inc., a general freight trucking company that also hauls fresh produce and meat, filed for Chapter 11 bankruptcy protection in the U.S. Bankruptcy Court for the Northern District of Illinois with plans to reorganize its business.

The East Dundee, Ill., shipping company listed $1 million to $10 million in assets and $10 million to $50 million in liabilities in its petition and said funds will not be available to pay unsecured creditors. The company operates with 183 trucks and 171 drivers, FreightWaves reported.

Nationwide Cargo's three largest secured creditors in the petition were Equify Financial LLC (owed about $3.5 million,) Commercial Credit Group (owed about $1.8 million) and Continental Bank NA (owed about $676,000.)

The shipping company reported gross revenue of about $34 million in 2022 and about $40 million in 2023.  From Jan. 1 until its petition date, the company generated $9.3 million in gross revenue.

Tight inventory and frustrated buyers challenge agents in Virginia

With inventory a little more than half of what it was pre-pandemic, agents are struggling to find homes for clients in Virginia.

Published

on

No matter where you are in the state, real estate agents in Virginia are facing low inventory conditions that are creating frustrating scenarios for their buyers.

“I think people are getting used to the interest rates where they are now, but there is just a huge lack of inventory,” said Chelsea Newcomb, a RE/MAX Realty Specialists agent based in Charlottesville. “I have buyers that are looking, but to find a house that you love enough to pay a high price for — and to be at over a 6.5% interest rate — it’s just a little bit harder to find something.”

Newcomb said that interest rates and higher prices, which have risen by more than $100,000 since March 2020, according to data from Altos Research, have caused her clients to be pickier when selecting a home.

“When rates and prices were lower, people were more willing to compromise,” Newcomb said.

Out in Wise, Virginia, near the westernmost tip of the state, RE/MAX Cavaliers agent Brett Tiller and his clients are also struggling to find suitable properties.

“The thing that really stands out, especially compared to two years ago, is the lack of quality listings,” Tiller said. “The slightly more upscale single-family listings for move-up buyers with children looking for their forever home just aren’t coming on the market right now, and demand is still very high.”

Statewide, Virginia had a 90-day average of 8,068 active single-family listings as of March 8, 2024, down from 14,471 single-family listings in early March 2020 at the onset of the COVID-19 pandemic, according to Altos Research. That represents a decrease of 44%.

In Newcomb’s base metro area of Charlottesville, there were an average of only 277 active single-family listings during the same recent 90-day period, compared to 892 at the onset of the pandemic. In Wise County, there were only 56 listings.

Due to the demand from move-up buyers in Tiller’s area, the average days on market for homes with a median price of roughly $190,000 was just 17 days as of early March 2024.

“For the right home, which is rare to find right now, we are still seeing multiple offers,” Tiller said. “The demand is the same right now as it was during the heart of the pandemic.”

According to Tiller, the tight inventory has caused homebuyers to spend up to six months searching for their new property, roughly double the time it took prior to the pandemic.

For Matt Salway in the Virginia Beach metro area, the tight inventory conditions are creating a rather hot market.

“Depending on where you are in the area, your listing could have 15 offers in two days,” the agent for Iron Valley Real Estate Hampton Roads | Virginia Beach said. “It has been crazy competition for most of Virginia Beach, and Norfolk is pretty hot too, especially for anything under $400,000.”

According to Altos Research, the Virginia Beach-Norfolk-Newport News housing market had a seven-day average Market Action Index score of 52.44 as of March 14, making it the seventh hottest housing market in the country. Altos considers any Market Action Index score above 30 to be indicative of a seller’s market.

Further up the coastline on the vacation destination of Chincoteague Island, Long & Foster agent Meghan O. Clarkson is also seeing a decent amount of competition despite higher prices and interest rates.

“People are taking their time to actually come see things now instead of buying site unseen, and occasionally we see some seller concessions, but the traffic and the demand is still there; you might just work a little longer with people because we don’t have anything for sale,” Clarkson said.

“I’m busy and constantly have appointments, but the underlying frenzy from the height of the pandemic has gone away, but I think it is because we have just gotten used to it.”

While much of the demand that Clarkson’s market faces is for vacation homes and from retirees looking for a scenic spot to retire, a large portion of the demand in Salway’s market comes from military personnel and civilians working under government contracts.

“We have over a dozen military bases here, plus a bunch of shipyards, so the closer you get to all of those bases, the easier it is to sell a home and the faster the sale happens,” Salway said.

Due to this, Salway said that existing-home inventory typically does not come on the market unless an employment contract ends or the owner is reassigned to a different base, which is currently contributing to the tight inventory situation in his market.

Things are a bit different for Tiller and Newcomb, who are seeing a decent number of buyers from other, more expensive parts of the state.

“One of the crazy things about Louisa and Goochland, which are kind of like suburbs on the western side of Richmond, is that they are growing like crazy,” Newcomb said. “A lot of people are coming in from Northern Virginia because they can work remotely now.”

With a Market Action Index score of 50, it is easy to see why people are leaving the Washington-Arlington-Alexandria market for the Charlottesville market, which has an index score of 41.

In addition, the 90-day average median list price in Charlottesville is $585,000 compared to $729,900 in the D.C. area, which Newcomb said is also luring many Virginia homebuyers to move further south.

“They are very accustomed to higher prices, so they are super impressed with the prices we offer here in the central Virginia area,” Newcomb said.

For local buyers, Newcomb said this means they are frequently being outbid or outpriced.

“A couple who is local to the area and has been here their whole life, they are just now starting to get their mind wrapped around the fact that you can’t get a house for $200,000 anymore,” Newcomb said.

As the year heads closer to spring, triggering the start of the prime homebuying season, agents in Virginia feel optimistic about the market.

“We are seeing seasonal trends like we did up through 2019,” Clarkson said. “The market kind of soft launched around President’s Day and it is still building, but I expect it to pick right back up and be in full swing by Easter like it always used to.”

But while they are confident in demand, questions still remain about whether there will be enough inventory to support even more homebuyers entering the market.

“I have a lot of buyers starting to come off the sidelines, but in my office, I also have a lot of people who are going to list their house in the next two to three weeks now that the weather is starting to break,” Newcomb said. “I think we are going to have a good spring and summer.”
