The REAP software has been used for the first five years in the English Language Institute of the University of Pittsburgh to teach vocabulary through reading words in context (Heilman et al., 2006). It allows the study of many questions in vocabulary learning, text learning, and motivation for reading. Past work suggests that ESL students may know the oral form of a word without knowing the written form and raise the possibility that this knowledge could help support learning word meaning from reading documents.
  
 +
This is an exploratory study that will use REAP to present oral and written input to students in the ELI LearnLab. For example, while allowing students to hear as well as see words should help learning, in some instances this form of oral assistance may create too much cognitive load, thus distracting the student from attending to word meaning. The goal is explore questions such as this while establishing materials and spoken language procedures that can work in the in-vivo ELI setting.

Here is an example of a typical instruction where the student can hear the word as he gets the definition to a word:

=== Findings ===
+
 
+
 
+
Personalization to match interests can lead to improved learning of the relevant knowledge components in a tutoring environment for vocabulary learning.  Students in the treatment group correctly answered a higher proportion of questions on target words that were practiced in the REAP tutor.
+
 
+
Second, personalization can compromise domain-based goals.  In the REAP tutor, an important domain-based goal is to give the student practice opportunities for many new target words.  However, students receiving personalization practiced fewer target words.  The difficulty in achieving the domain-based goal of practicing many unknown words is due to the fact that the REAP tutor often could not find texts that included multiple target words and also matched personal interests.
+
 
+
Third and finally, if the challenges of negotiating personalization and domain-based goals are met, personalization can lead to improvements in overall learning.  Students with personalization appeared to learn the words they practiced with greater frequency but practiced fewer target words, and as a result did not perform reliably differently than their controls on the overall post-test measure for cloze questions.  The researchers attributed this lack of a difference to the fact that, in many cases, the tutor had to choose between interesting readings and those with more practice opportunities.  However, the availability of readings that are both interesting and provide ample practice is a technical issue which can be solved in a straightforward manner by increasing the size and coverage of the corpus of available practice reading passages.
+
 
+
=== Explanation ===
+
 
+
Students in the treatment condition with [[personalization]] performed slightly better on average (M=35.5%, SD=14.9%) in terms of overall post-test scores compared to students in the control condition (M=27.1%, SD=17.2%).  However, this difference was not statistically significant. 
+
 
+
[[Image:graph40.jpg|500px]]
+
 
+
There is evidence that the difference in post-test scores is due to increased interest leading to deeper processing of the reading practice texts.
+
 
+
Responses to questionnaires following each reading show the interest level of students using the REAP tutor.  The questionnaires asked students to indicate on a scale from one to five their interest inr the preceding text.  The distributions of post-reading interest ratings for students in the treatment and control conditions are shown below.
+
 
+
[[Image:Interest_combined.jpg|700px]]
+
 
+
Students were also given an exit survey during their last week of practice with the tutor that asked them, among other questions, for to indicate whether they agreed with the statement, “Most of the readings were interesting.”  The ratings were on a scale from one to five, with five indicating strong agreement and one indicating strong disagreement.  Exit survey interest ratings by students in the treatment condition were significantly higher (p<0.05) than the ratings by students in the control condition.  The mean response for students who received personalized readings was 3.18, while it was 2.65 for students in the control condition.
+
 
+
Further analysis of post-test scores reveals that students did learn more of the words that they actually practiced in REAP.  The post-test contained 40 questions for target vocabulary words.  Many of the students did not practice 40 words, so performance on practiced words alone was analyzed.  Students in the treatment condition scored higher (N=16, M=50.3, SD=20.1) on questions for words seen in readings than did students in the control condition (N=19, M=32.4, SD=18.9).  A two-tailed t-test for independent means verified that this result is statistically significant (t=2.719, df=33, p=0.005).  The difference of scores between the two groups was 17.9% (95% CI = 4.5%, 31.3%), which corresponds to a large effect size of 0.85.  This result indicates that [[personalization]] improved learning for the words that students saw in readings, which is in line with previous findings that intrinsic motivation leads to improved learning.
+
 
+
 
+
[[Image:post_just_practice.jpg|400px]]
+
 
+
However, students in the treatment condition that included [[personalization]] saw fewer words in their training sessions (N=16, M=12.0 , SD=1.13) than students in the control condition (N=19, M=16.3, SD=0.87) (t=-2.9, df=33, p=0.006).  Average time on task was essentially the same for students in both conditions.  Students in the treatment condition spent slightly longer on each reading.  The main reason, however, for the difference in the average total number of words practiced was that students for whom the tutor provided personalized instruction saw fewer words (M=3.41, SD=0.55) per practice reading passage than students in the control condition (M=4.07, SD=0.83) (t=2.929, df=33, p=0.006).
+
 
+
Thus, when the tutor used [[personalization]] as a factor in the selection of readings, it chose readings that were less valuable according to other factors.  Specifically, this result shows that by personalizing instruction, the tutor was not able to provide practice for as many words.  Of course, the practice that it did provide was better, as is shown in the previous result that for words student did practice, [[personalization]] appeared to increase learning.
+
 
+
The reduced number of target words per text with personalization is a technical issue which can be avoided in a straightforward manner by increasing the size of the database of readings.  With more readings, the tutor can find texts that both have ample target words and cover topics of personal interest.
+
 
+
 
+
[[Image:words_per_reading.jpg|400px]]
+
 
+
There is a possibility that the students in the treatment condition who were seeing fewer words in each reading were learning more of the words simply because they had fewer to learn per reading.  To rule out this hypothesis, regression analyses (multiple linear regression) with overall post-test performance and performance for practiced words as the dependent variables.  In both regression analyses, the number of target words per reading was not a significant predictor of performance.  In fact, the number of target words per document was slightly positively correlated with post-test performance in both cases.  This result seems to rule out the possibility that students were learning more target words in the treatment condition because they were seeing fewer words. 
+
 
+
 
+
[[Long-term retention]] test results showed no reliable differences because of a small sample size.  The test was administered to students who stayed in the ELI in the subsequent semester, which constituted only a fraction of the original sample.

Abstract

The term “Multimodal learning” refers to learning where two or more different modes are used in order to integrate a Knowledge Component. In the particular case of vocabulary, the typical modes would be:

  • Visual ( visual word form )
  • Auditory ( auditory word form )
  • Pictorial ( picture of the concept subjacent to a word )

The object of this study is to evaluate the relationship between the visual and auditory modes in learning vocabulary.

Word learning episodes can occur through writing and speech. Spoken language knowledge is important as a foundation for reading, and may support word learning through reading. The objective of this study is to investigate under what conditions does spoken language input, when combined with written input, lead to better word learning for L2 learners.

The REAP software has been used for the first five years in the English Language Institute of the University of Pittsburgh to teach vocabulary through reading words in context (Heilman et al., 2006). It allows the study of many questions in vocabulary learning, text learning, and motivation for reading. Past work suggests that ESL students may know the oral form of a word without knowing the written form and raise the possibility that this knowledge could help support learning word meaning from reading documents.

This is an exploratory study that will use REAP to present oral and written input to students in the ELI LearnLab. For example, while allowing students to hear as well as see words should help learning, in some instances this form of oral assistance may create too much cognitive load, thus distracting the student from attending to word meaning. The goal is explore questions such as this while establishing materials and spoken language procedures that can work in the in-vivo ELI setting.

Here is an example of a typical instruction where the student can hear the word as he gets the definition to a word:
