[Workplace] Optimal number of students in a classroomMiriam Burt miriam at cal.orgFri Jan 20 16:53:23 EST 2006
My colleague, Dr. Julie Mathews-Aydinli, did the following research on the topic of how the number of students in the second language classroom affects their learning of the language and found basically that the research backs teacher perceptions that large classes are a negative factor in learning the language. Below is a summary (in her words) of the research, bibiliographic info, and abstracts of all the research she looked at. It's long but detailed. She highlighted and bolded important sections - but I don't know if those marking will make it to the list. At any rate, hope this helps make the case... Miriam Miriam Burt Center for Applied Linguistics 4646 40th Street NW Washington, DC 20016 (202) 362-0700 (202) 363-7204 (fax) miriam at cal.org from Julie: Here's my final report! If we look at the research over the last 25 years, there is generally a consensus that supports what most teachers would report, that large classes are a negative factor in effective teaching and learning of a second language. Several research studies have shown the negative affects of large classes (e.g. Coleman, 1989; Gonzales, 2003; Oberg, 1993; Ozerk, 2001; Tsuji, 1989). Many others provide further anecdotal evidence of large class size as a problem (e.g. Berney & Stern, 1990; Leki, 2001; and Morgan, 2000), and a theoretical article in TESOL Quarterly strives to provide a model for understanding the various ways that large class size negatively affects second language learning (LoCastro, 2001). Still, there are studies that suggest that large class size is in fact not a problem. A closer look at these studies seems to reveal a couple of possible qualifications for such an assessment of the class size issue. First, many of these studies (e.g. Elango, 1993; Kumar, 1993; Vuppala, 1993) are English as a Foreign Language studies, and are based in contexts in which even the researchers admit that large classes are an "inescapable aspect" of language teaching (Vuppala, 1993). One would have to question therefore whether the findings of these studies, many of which emphasize also seeking ways to find benefits in the large class size, are simply attempts to make the best of a bad situation, rather than actual 'proof' that large classes are a positive thing. The other type of study that tends to argue large classes are not a problem also has a caveat of sorts, that they usually look at large language classes in which other, innovative approaches are in place (e.g. Knight, 2000). For example, Bolton (1988) is a study from a community college ESL class in which a teacher opted to redistribute three classes of 25 students into one class of 75 but then use the extra time to give tutorials and group conferences etc. With these extra activities, a statistical comparison on the performance of the students in the large group with that of students in regular smaller classes was not significantly different. If anything, there were suggestions that the large group students performed slightly better. One would automatically question however whether there might not have been some effect of the teacher and students putting 'extra' effort into this new and experimental situation that may have caused some problems for purely statistical validity. Looking at the research overall therefore, I think one has to agree that it confirms teachers' widespread perceptions that large classrooms not only make teaching more difficult, but that they also have negative affects on the students' learning. ACTUAL STUDIES SHOWING LARGE CLASS SIZE HAS NEGATIVE AFFECT DN: Database Name Linguistics and Language Behavior Abstracts TI: Title Large Classes and Student Learning AU: Author LoCastro, Virginia AF: Affiliation U Americas, Puebla, Mexico SO: Source TESOL Quarterly, 2001, 35, 3, autumn, 493-496 AB: Abstract To address the question of the effect of class size on second language instruction & learning, a model parallel to R. C. Gardner's (1985) model of attitudes & motivation in language learning is suggested. Fifteen problems of language pedagogy related to class size are grouped under pedagogical, management-related, & affective categories. The importance of learners' opportunities to interact with the target language, supported by various recent hypotheses, suggests that the maximum number of students for effective language learning in a classroom is 15. In light of the worldwide democratization of education, class size is identified as one of the sociocultural variables underlying educational systems. 8 References. J. Hitchcock Author Oberg, Robin. Title Effects of ESL Time and Class Size on the Achievement of LEP Students. Date of Publication November 1993 Abstract A study investigated the relative effect of 45-minute and 90-minute daily instruction in English as a Second Language (ESL) on limited English proficient (LEP) first-graders' language and overall achievement. The subjects were two groups of pupils from different schools: (1) 13 pupils from 7 language backgrounds, receiving 45 minutes of instruction daily; and (2) 17 pupils representing 5 native languages, receiving 90 minutes of instruction. Data used for analysis included reading and language test scores, oral language proficiency test scores, and teacher-provided information on overall grades. Results indicate that the pupils in shorter ESL class, which was also smaller, made higher grades in the regular classroom than did the other group. The short-class group also had higher oral proficiency test scores, but not significantly higher reading and language test scores. It is concluded that class size and time may have some significant effect on regular classroom achievement and oral language achievement but not may not affect scores on standardized achievement tests.

Availability Overseas Education Unit, School of Education, University of Leeds, Leeds LS2 9JT, United Kingdom (individual reports 0.50 pounds sterling, surface mail). Date of Publication 1989 Abstract This report confirms anecdotal evidence that language teachers do find large classes to be problematic, collates data on class sizes in various parts of the world, and investigates the possibility of defining a large class, at least from the teachers' points of view. The first section is introductory. The second presents findings of a small-scale (n=46) investigation of the perceptions of native-speaking and non-native-speaking teachers of English as a Second Language (ESL) of the characteristics of large classes. The third section describes a larger study of ESL teachers' experiences with and perceptions of class size in Great Britain, Turkey, Indonesia, Madagascar, Mali, Japan, Greece, Jordan, and Spain. Section 4 discusses what the study tells about actual class sizes, and section 5 is a detailed analysis of the relationship between teachers' experiences and their perceptions of class size. It is concluded that class size varies across countries and probably across institution type. No evidence that teachers share a universal conception of ideal class size was found, but there appeared to be a positive correlation between the largest class regularly taught and both perceptions of an ideal class and perceptions of what a large class is. Further research is recommended. (MSE) Result <7> Accession Number ED322751 Author Coleman, Hywel. Institution Leeds Univ. (England). School of Education[BBB27921], Lancaster Univ. (England).

Availability Overseas Education Unit, School of Education, University of Leeds, Leeds LS2 9JT, United Kingdom (individual reports 0.50 pounds sterling, surface mail). Date of Publication 1989 Abstract This is the second of 12 research reports on the phenomenon of language instruction within a large class environment. The report is written in five sections. The second section (following the introductory first section) discusses the reasons for studying large classes in language instruction, including the facts that teachers find large classes cause difficulties that affect teaching performance, that large classes are becoming commonplace, and that very little has been done to address the problem or train English-as-a-Second-Language (ESL) teachers to instruct under such difficult circumstances. The third section outlines and explains the project's activities, namely, creating a bibliography, networking, organizing colloquia, and promoting and undertaking research. Section 4 presents the nine specific questions that the project is attempting to study. These include the following: the teacher's concerns, the extent of the large class phenomenon, the reasons for the occurrence of large classes, attitudes towards large classes, data collection in large classes, the performance of large classes, strategies in large classes, language acquisition in large classes, and experiments in large classes. Section 5 summarizes and presents conclusions. (GLR) Accession Number ED308335 Author Tsuji, Gerry K. Institution Toronto Board of Education (Ontario).[SFO88000] Title A Research Report on the Toronto Board of Education's Response to Adult Literacy. Date of Publication May 1989 Abstract Since 1985, the number of adult literacy programs provided by the Toronto Board of Education has increased by 500 percent and learners by almost 300 percent, so that in 1989, almost 9,000 adults are enrolled in nearly 700 classes. Two distinct groups are being served: a unilingual group, most of whom are Canadian-born, English-speaking young adults, and an English as a second language (ESL) group who are typically literate in a language other than English. The differences between the two groups have consequences for program planning, instructional methods, locations of classes, and outreach. Classes are scheduled at most times of the day. Unilingual learners tend to take more hours of instruction per week than ESL learners. Generally, all learners are pleased with their classes, although few attend for more than a year, and the dropout rate is high. Gains for unilingual learners are associated with good attendance, amount of instructor's experience, and a classroom that promotes independent learning. ESL learners' gains are related to length of participation in programs, level of class, the amount of inservice training taken by their instructors, class size (about 10), and classrooms with high levels of participation, interest, and respect, by both learners and instructors. Lead instructors spend at least half their time on administration, although they feel their primary role is program support. Program administrators generally feel that learners are being well served, although specific areas were noted as requiring attention, such as more funds to advertise and integrating adult classes with day school programs.

Through qualitative and quantitative methods, this study explores two models of the Two-Way Immersion Language Program: (1) the 90/10 model, implemented in one school since 1997, which starts kindergarten with 90% Spanish and 10% English instruction until it gradually reaches equal time by fifth grade, and (2) the 50/50 model, adopted by three schools in 2000, which teaches equal percentage time of English and Spanish in all grade levels. The study used a triangular method of data collection by (1) conducting in-depth face-to-face interviews using structured open-ended interviewing protocols for teachers, principals, and district administrators, (2) collecting data from 278 students, and (3) conducting classroom observations in the four school sites. Findings showed that 15% of students did not continue in the programs across all of the schools, and the dropout rate was higher in early grades. Findings of student achievement indicated that students in the two language models scored higher in mathematics than in reading on English and Spanish standardized tests. Statistically significant improvement in math in English standardized tests from grade-to-grade was found in two groups of first and fourth graders in the 50/50 and 90/10 model respectively. Further, students in both models dropped in their percentile ranks from grade-to-grade in English reading; however, two groups of third and fourth graders in the 90/10 model showed a slight improvement. Students from the two models scored higher on Spanish than on English tests, however the improvement varied. First and fourth graders in the 90/10 model significantly improved in math on Spanish tests. First graders in both models significantly improved in Spanish reading, while second and third graders in the 90/10 model significantly dropped in their percentile ranks in Spanish reading. These findings suggest the possible effects of small class size, teachers' backgrounds and attitudes, principals' leadership styles, teachers' actions toward parental involvement, and instructional support from teacher aides as significant factors that may be related to achievement scores.

In mainstream classes the bilingual students were taught together with their monolingual Norwegian peers. The study shows that there are inter- & intragroup differences with respect to (1) teacher-student verbal interaction; (2) academic questioning; & (3) curriculum-related performance of students in small classes compared with large classes. The bilingual minority students, in general, & bilingual minority girls, in particular, benefit from civics lessons in small classes more than they do in large classes. It is suggested that by creating rich possibilities for teacher-student verbal interaction & curriculum-oriented academic questioning, small classes can provide conditions for better academic performance in content-area subjects, eg, civics, for bilingual students in general, & bilingual girls, in particular. 7 Tables, 42 References.

The particular situation of writing instruction in non-English dominant countries has received insufficient attention, especially in light of some of the claims for the role of writing coming from the "center" countries. English language teachers, particularly those teaching in non-English dominant countries, who give substantial attention in their courses to teaching writing in English, face a number of challenges. This article discusses two main categories of challenges. In the first group are challenges writing teachers face daily, such as class size, time constraints, accommodating local needs, & coping with problems connected to lack of both teacher experience in teaching L2 writing & student training in L1 writing. In the second group are challenges of a more ideological nature that are perhaps less obvious but more powerful & far-reaching, including the need to justify the large investment required on the part of institutions & individuals in order to teach L2 writing, the right to resist center imposed materials & methods, the need for dialogue with students about the role of writing in their lives, & the need to make L2 writing enhance learner options rather than limit them so that for learners, writing in the L2 becomes not a pointless additional burden but a powerful means of accomplishing personal goals. 25 References.

The various categories cannot be entirely separated from each other, & in fact provide information for possible future research about class size in the post-secondary second-language classroom. 100 References.

Date of Publication February 1990 Abstract Chapter I/Pupils with Compensatory Educational Needs programs in English as a Second Language (ESL) served students at 78 high schools in New York City, supplementing tax-levy-funded ESL classes in those schools serving limited-English-proficient (LEP) students. Chapter I of the Educational Consolidation and Improvement Act funded ESL and bilingual classes, bilingual guidance counselors, and paraprofessionals. Three program models were provided, each for a different type of high school, with specific formulas for allocation of funds at different instructional levels. Evaluation was conducted through interviews, data collection, and observation. Each participating school had diverse problems requiring different Chapter I programs, including native language illiteracy, increases in the number of immigrant students unprepared for the high school curriculum, social and economic difficulties facing new immigrant students, and large classes. In some cases, the constant influx of new students made functional grouping impossible, placing students at diverse ESL levels in the same class. Recommendations for program improvement include: examining effects of new LEP eligibility rules on demand for Chapter I funds to supplement tax levies, evaluating effects of class size on ESL learning; and exploring the effectiveness of the program model as it relates to student acquisition of English language skills and time needed to mainstream.

Yet, to address the surging Spanish enrollments at the university level, the Spanish department at Central Michigan U began an experimental program challenging that tenuous relationship. While most beginning 4-hour language courses meet four times a week with a college instructor & average about 25 students, the experimental classes meet two times & have 60 students. For the other 2 hours, the 60 students are divided into groups of 15 & work with undergraduate language majors who are supervised by the large-group instructor. The description of the program including quantitative & qualitative assessments comparing the traditional & experimental groups may serve as a model for other undergraduate programs of similar size. 1 Table, 18 References.

Students (N = 80) from a variety of disciplines were chosen at random & asked to identify their major problems in the language classroom. Teachers (N = 11) responded to a similar survey that asked what problems they encountered while teaching English. Their responses were grouped into three categories: teacher-,learner-, & curriculum-based. Both students & teachers were asked to prioritize seven key issues gleaned from their initial responses. Teachers gave large class size the highest priority, students gave class size their lowest priority. When questioned further, a sample of students said that class size was irrelevant if there was sufficient motivation & interest. Teachers felt that large classes increased their workload, prevented them from catering to individual needs, & forced them to spend too much time on"law & order" problems. A minority of teachers felt that the appropriate pedagogy could lead to effective learning even in the largest classrooms.

Studies suggest that learners in these classes employ different strategies to accommodate their learning context. Teachers, however, continue to use the traditional lecture method as a means of managing the large class. In India, the heterogeneity of large classes seems more problematic than the actual size. Large classes contain a mix of students from regional medium schools & students from schools where English is the language of instruction, with very diverse backgrounds & language abilities. This situation is compounded when teachers inadvertently focus on one group while ignoring others. Researchers have begun to consider the possibility that this heterogeneity might positively influence language learning, as students' different abilities become a resource, rather than an obstacle for learning. Strategies such as group work & peer-consultation are discussed. The role of teacher attitude & the importance of English instruction are emphasized. L.

Postobservation interviews with the teachers (N = 2) are also utilized. Findings suggest that class size might not be a crucial variable in determining the amount of opportunities for learner interaction made available by a teacher. 2 Tables, 11 References. ________________________________ From: workplace-bounces at nifl.gov [mailto:workplace-bounces at nifl.gov] On Behalf Of Miriam Burt Sent: Friday, January 20, 2006 11:34 AM To: The Workplace Literacy Discussion List Cc: Julie Mathews Subject: Re: [Workplace] Optimal number of students in a classroom Importance: Low Peter and others, this is great!

Says there is a classroom efffect for short classes (45 min), but this study did not see much gain on standardized tests. My answer to that is the question: How different is the standardized test from the material the students were using in the classroom? Perhaps we need a study on transfer effects of classroom English to real life English and the language of the tests being used. Gilstrap, S.
