In recent times there has been a lot of discussion about bilingual education.
In the 2009 U.S. Supreme Court decision, Horne v. Flores, the majority opinion stated, "Research on ELL instruction indicates there is documented, academic support for the view that SEI (Structured English Immersion) is significantly more effective than bilingual education.
"Proponents of bilingual education claim that it is not only easier for students to learn English if they are literate in their first language, but that such students will learn English better and become bilingual and biliterate.
Proponents further claim that effective bilingual programs strive to achieve proficiency in both English and the students' home language.
Dual language or Two-Way bilingual programs are one such approach, whereby half of the students speak English and half are considered English language learners (ELLs).
The teacher instructs in English and in the ELLs' home language.
The dual purpose of this type of classroom is to teach the children a new language and culture, and language diversity in such classrooms is seen as a resource.
Programs in English only eradicate the native languages immigrants bring to this country, while dual language bilingual programs serve to maintain such languages in an "additive" context, where a new language is added without the first being lost.
One paper states that two-way developmental bilingual education programs in elementary school have the most success in language minority students' long term academic achievement.
These students will maintain their gains in academic performance in secondary level academic classes.
Another study shows the positive results of a two-way bilingual education program.
Some people make the mistake that once a student can converse in English (Basic interpersonal communication skills - BICS), they will naturally perform well academically (cognitive academic language proficiency - CALP) in English.
It has been postulated that BICS and CALP are two different sets of skills.
Opponents of bilingual education claim that students with other primary languages besides Spanish are placed in Spanish classes rather than taught in their native languages and that many bilingual education programs fail to teach students English.
Critics of bilingual education have claimed that studies supporting bilingual education tend to have poor methodologies and that there is little empirical support in favor of it.
The controversy over bilingual education is often enmeshed in a larger political and cultural context.
Opponents of bilingual education are sometimes accused of racism and xenophobia.
This is especially so in the case of such groups as English First, which is a conservative organization that promotes the stance that English should be the official language of the United States.
In Milwaukee, Wisconsin and other cities, Minister of education of the Young Lords, Tony Baez and others held marches and other activities to promote bilingual education.
Proponents of bilingual education are frequently accused of practicing identity politics, to the detriment of children and of immigrants.
"To aid and monitor the education of English language learners (ELL)through mother-tongue and English education, the federal government enacted the Bilingual Education Act (Title V11) of the elementary and secondary Education Act in 1968.
As an offshoot of president Lyndon B. Johnson's war on poverty, the act strove to help disenfranchised language-miniority students, especially Hispanics.
Unfortunately, the acts aims were somewhat ambiguous.
As Crawford (2000a) writes 'enacted at the apex of the Great Society, bilingual education act of 1968 passed congress without a single dissent.
Americans have spent the past 30 years debating what it was meant to accomplish'" (p. 107). 
In line with most German states, the German Secondary Department offers an eight-year Gymnasium course.
The curriculum is based on the core curriculum of German schools in Southeast and East Asia, which in turn is based on the curricula of the state of Thuringia.
The school offers English, French, Latin and Mandarin programmes.
GSIS is one of the first German Schools Abroad to offer the bilingual German International Abitur Examination (DIAP).
As much as 50 percent of the Abitur exams can be taken in English.
In order to prepare students for these exams, Geography is taught bilingually from K07 to K09 and in English from K10; history is taught bilingually in all years from K08.

In 1990, the League of United Latin American Citizens (LULAC) won a class action lawsuit against the state Florida Department of Education that required educators to be trained in teaching English for Speakers of Other Languages (ESOL). 
The Städtisches Gymnasium was founded in 1520, and split into the Goethe-Gymnasium and the Lessing-Gymnasium in 1897.
