I still remember the first time I became angry with a teacher. I was in first grade and just received my first “real” report card. Unfortunately, it wasn’t a glowing evaluation. The exact details have faded, but I remember being most disappointed by the math and science grades. Those were my favorite subjects. I was usually one of the first students to raise my hand and ask questions during those activities — and my responses were always met positively. I even made a firm decision to be a pediatrician when I grew up. So when my teacher said I needed more help with math and science, I was furious. I knew I understood the concepts, but as a bilingual Spanish-English speaker, I would simply get stuck on reading some the academic language. How could she not see that?
How teachers can help their dual language learners develop early math skills
“Classrooms using heterogeneous ability groups with ample instructional time offer significant benefits to both young DLLs and their non-DLL peers.”
In later years, the school realized that it needed to adjust to serve the growing bilingual population in our community. This led to palpable changes in my classrooms. One teacher even shared basic Spanish medical terminology with me for a project. She said being able to speak both languages as a doctor would enable me to help more people — she saw my growing bilingualism as an asset. As both my Spanish and English language skills advanced, my grades rapidly improved. However, the embarrassment, low confidence, and fear of “inappropriately” speaking Spanish lingered. As an adult, I often think back to those early years in school and what could have been different. Fortunately, I am not the only one pondering this question.
Optimal instructional techniques and classroom organization strategies for dual language learners (DLLs) are widely debated. Teachers and researchers alike are exploring which methods best leverage DLLs’ language abilities and boost their achievement.
A recent study by researchers Rachel Garrett and Guanglei Hong tests the effects of grouping and time allocations in the classroom on the math performance of DLL kindergartners, as measured by direct assessment and teacher ratings. Specifically, the study explored the effects of access to small group instruction, different types of small group instruction, and total math instructional time. Overall, their results suggest that teacher ratings of DLL students’ abilities are lower when they use “homogeneous math grouping” in their classrooms.
Despite a near universal desire for an end to Venezuela’s manmade disaster, sending in U.S forces to take out the Maduro regime would be counter-productive. It should be categorically rejected by interim president Juan Guaidó, not to mention the Trump administration.
The firing of undocumented workers at Trump's golf clubs just shows how the practice of employing immigrants without legal work papers is much more common than we might imagine. Such is life in the United States.
The Trump administration should be wary of fueling fake news predictions about an imminent American invasion which unrealistically raises expectations about Maduro's removal.
At some point we will have to accept the fact that the border between Mexico and the United States is nothing more than an invention.
The United States has had a major role in the evolving drama of the fight for democracy in Venezuela and Nicaragua. And so far, it’s been surprisingly coordinated, a veritable model of multilateralism.
Has the Maduro regime reached breaking point? It remains hard to say, but tomorrow is another - more hopeful - day for the restoration of democracy in the South American nation.
It’s impossible to get into Trump’s head but what comes out of his mouth are racist remarks. But, saddest of all are the millions who tolerate his views, cheer him on and emulate his behavior.
The time is well past due for the U.S. government to conduct a thorough review of leaders and their senior colleagues before they leave office to determine if they merit visas.
Previous research provides strong evidence that small group instruction can help students perform better particularly in math. When forming these groups, teachers generally use either homogeneous groups (similar-achievement levels together), heterogeneous groups (mixed-achievement levels together), or a combination of the two.
When Garrett and Hong analyzed differences in exposure to these types of grouping strategies. They found that both DLLs and their non-DLL peers were more often exposed to homogeneous groups than to heterogeneous level groups.
So: does teachers’ choice of grouping strategy affect students’ math performance? Perhaps. Garrett and Hong did not find any significant relationships between grouping strategies and direct math assessment results. However, their results do suggest a relationship between grouping strategy and teacher ratings of’ math performance. For instance, use of homogeneous groups reduces teachers’ ratings of their DLLs’ math performance by 35 percent.
The researchers also test if the amount of math instruction time affects DLLs’ achievement. Obviously, it would seem that more instruction should lead to better performance. Indeed, that’s generally what the study found. However, teachers’ ratings of math performance drop over 40 percent in classrooms using the homogeneous level strategy, regardless of the amount of instructional time, providing more evidence for a negative relationship between this grouping strategy and teachers’ ratings of student ability. Essentially, it is possible that teachers who place all DLLs in one group may cultivate a perception that the group is lower performing and consequently lower their expectations. This finding is particularly concerning given previous research that suggests low teacher expectations can lead to lower student academic performance.
Overall, the study’s results warn that homogeneous ability groups may have detrimental effects for teachers of DLLs and their students. By contrast, classrooms using heterogeneous ability groups with ample instructional time offer significant benefits to both young DLLs and their non-DLL peers. However, the researchers highlight that future research is needed, especially considering factors like level of English proficiency and baseline math proficiency, to fully understand these relationships.
While I did not follow my initial dream of becoming a pediatrician, there are thousands of young bilingual (and multilingual) students around the country who will. In order to boost these young DLLs’ math and science achievement, schools will need to experiment with and consider the myriad pedagogical strategies that can support their success.
