Questions
for Reflection and Discussion/April 2001
Linguistic and
Psychological theory
1.Why
do Curtain & Pesola state that "simply to place the child in the target
language setting(...) is not an approach that will make it possible to bring
languages to every child"? (Chapter four:51). Use some hypotheses of second
language acquisition theory to back up your argumentation.
Because
not all children have the same characteristics and the stages of development not
always coincide among children. It also depends on the creativity of the teacher
and what is more important language should be meaningful and the input
comprehensive (Input hypothesis)
2.
What are the conditions for effective monitor use?(Curtain &Pesola:52). Do
these conditions apply to everyday speech? Give examples to account for your
answer.
Speaker
must know a rule , have time to thing of it and apply the rule and be in a
setting in which it is appropiate to focus on form. These conditions do not apply to
everyday speech and if we worry too much on rules , we miss the opportunity to
communicate.
3.Comprehensible
output (Swain 1985). To what extent do you think that output is important for
students acquiring a language? Discuss in relationship to Krashen's Input
theory. See The Input theory: Issues and
Implications.1986:35
According
to Swain the attempts at
communication (output) help the student to acquire a language , it is important
for students to receive corrections of communicative errors , which inhibit
comprehension(comprehensible output). This mechanism works effectively if the
student is not interrupted to correct grammatical errors , as this discourages
the student to communicate.
On
the other hand, Krashen minimizes the role of output in the acquisition process.
He says that language can be acquired simply by comprehensible
input.
4.How
do the findings in the field of cognitive psychology support Krashen's
affirmation that "hypotheses are tested on a subconscious level". (Krashen
1986:36)
This
statement is supported by one of the principles of cognitive psychology that
says that students are active
participants in the learning situation controlling and shaping their own
learning processes ,. He feels that learners test hypotheses by subconsciously
matching form in the input to their own notions about the
language.
5.
How can you as a teacher make sure
the language presented will be comprehensible to the
students?
First
of all I should try to make language meaningful to students , of high interest
and with relevant information to them. Then I can use a slower rate of speech,
more distinct pronounciation motherese , teacherese ,shorter less complex
sentences, more concrete references, rephrasing and repetition, more frequent
meaning checks, gesture and visual reinforcement and provide students with
meaningful listening experiences.
6.Discuss
Leslie Hart's definition of learning. What are the dangers of simplified
input?
Leslie
Hart defined Learning as the the
process of extracting meaningful partners from the rich environment and shaping
it into a program: a fixed sequence of behaviour for accomplishing some intended
objectives. The problem is that this way of extracting partners from the rich
input implies a simplification of the input , which in many cases can inhibit
learning .
7.Whithin
the categories of Whole Language as presented by Edelsky 1992: beliefs about
language, beliefs about language development and beliefs about learning, choose
two aspects of each and discuss them in relation to your experience as learner
and future teacher. Which aspects seem to be the most difficult to apply?
Beliefs
about language:
¨Language
is profoundly social and depends on a social context¨ : This belief together
with the other one about learning ¨Learning is a social process¨ are completely
true but I feel they are quite difficult to apply since we cannot face real
situations unless we travel abroad or we have the chance to talk to a native
speaker some time in our life. As a
learner of English (being primarily taught through drilling and repetitions)
and I have always dreamt of real
everyday life experiences and I was lucky since when I worked as a bilingual
secretary I had the chance to meet many native speakers and talked to them on
the phone , facing real problems and working them out in English. This was a
really rewarding experience and this is the moment when a learner of a language
can realize about the meaning of it.
¨Language
takes several forms, oral , written, sign, and each is valid in its own right.
None is derived from or dependant on the other and they all share the same basic
characteristics and can develop simultaneously : I think that all form of
language are necessary to provide a comprehensible input. The oral form is the
most difficult to apply if it is not provided with active participation of the
students in real situations. The written form is also quite difficult specially
considering that students are more engaged in the oral
work.
Beliefs
about learning:
¨Learning
is a social process¨: Already developed in beliefs about
language.
¨Learning
involves hypothesis testing¨: That is true , corrections when properly made play
an important role in hypothesis testing and therefore in learning . It
depends on the teacher skills to
correct when it is necessary without inhibiting the
communication.
Beliefs
about language:
¨Language
is learned through actual use to achieve personal purposes, it is not learned
through drill and practice for its own sake: I agree and it is better to work on
topics that interest students and with real information.
¨Language
learning is both natural and social¨: It is true, it is the natural product of
social interaction but it is also difficult to apply since we do not have many
social places in our country where people can use English to communicate
naturally.
Krashen,
Stephen & Tracy Terrell.1983. The Natural Approach. Language Acquisition
in the Classroom. Hayward, California: Alemany Press. Chapter 1, 2
& 3
Chapter
one
1.
What is the evidence Krashen gives for considering the Natural Approach as a 'traditonal approach'?
Most people
acquire another language through communicative practice in real situations using
the language for specific functions
, without instruction in its grammar and this is how most people have
¨traditionally¨acquired languages.
2.The
Audiolingual Method. What were the components of the Army language course?
Discuss the basic tenet of audiolingualism.
They were two:
The drill sessions and the conversation sessions.
In the drill
sessions situational-based dialogs were practiced and memorized. These sessions
were followed by conversations sessions with a native speaker and were usually
constructed around real life situations, often those of the dialogs. The basic
tenet of audiolingualism is focused on the importance of oral skills (listening
and speaking) before reading and writing.
3.
What are Krashen's criticism to the cognitive movement? Particularly in relation
to this quote: "learned competence cannot directly 'become' acquired
competeence" (Krashen 1986:38)
Acquired
competence is quite different from
learned competence since when you acquire something it is subconsciously so , it
is long lived and easily remembered.
4.Discuss
the following quotation from Newmark& Reibel (The Natural Approach:17) in relation to
Krashen's Natural Order Hypothesis.
(...) Sistematic
teaching of structure (as in structure drills) imposes a formal rather than
useful organization of language material (...)
The structures of
a language are learnt through real communication not through structure
skills.
5.
The Silent period is considered to be an acitve period. Why is this so? What is
the acquirer building up? (Krashen 1986:9)
The silent period
always takes place when we are
exposed to a second language. During this period we are being active by
listening and memorizing phrases and sentences we hear frequently and whose
meaning we do not understand completely . We are building up competence by
listening , via comprehensible input. It lasts for about six months and it is
when second language production emerges.
6.Why
cannot spoken fluency be taught directly but rather it emerges? Contrast
cognitive psychology to behaviourist principles.
Because
students, as active participant in the learning situation , control and shape
their own learning processes . Their own internal motivation drives the learning
process. In contrast, for the behavioral psycologist , the student is considered
to be a relatively passive subject, to be manipulated through reinforcement
techniques and drill.
The
ability to speak or write fluently in a second language will come on its own
with time.
-----------------------------------------------------------------------------------------------------------
Below you will find part of the answers to the questionaire. They were sent by Santiago Feldman on behalf of all the students of Didactics I Afternoon Shift.
Below you will find the answers that Amelia Mauroni, Afternoon Shift, has sent us :
Curtain,
Helena & Carol Ann Pesola. 1994. Language and Children: Making the
Match. White Plains, New York: Longman, Chapter
4.
Linguistic and Psychological
Theory
1. Why do Curtain and Pesola state
that "simply to place the child in the target language setting (...) is not an
approach that will make it possible to bring languages to every child"? (Chapter
4: 51). Use some hypothesis of Second Language Acquisition Theory to back up
your argumentation.
Because there must be an
understanding of the principles of child development and of the characteristics
of children at different stages of development, and this will help prepare the
teacher to create curriculum and activities that bring languages and children
together effectively.
Some hypotheses:
* Input Hypothesis, which suggests
that the most important factor in the amount of language acquired by a learner
is the amount of comprehensible input to which that learner is exposed and it
must be used in such a way that the message is understood by the student at all
times, even though every word or message may not be familiar. This is
accomplished through the use of gestures, examples, illustrations, experiences
and caretaker speech.
* Affective Filter Hypothesis:
Krashen relates these experiences to language acquisition by describing a filter
which the brain erects to block out second-language input and which goes up in
the presence of anxiety or low self confidence or in the absence of motivation.
The filter goes down and the input can come through when motivation is high,
when a student is self-confident and when the learning takes place in a
relatively anxiety-free environment.
2. What are the conditions for
effective monitor use? (Curtain & Pesola: 52) Do these conditions apply to
everyday speech? Give examples to account for your answer.
For the monitor to work
effectively, the speaker must know the rule, have time to think of the rule and
apply it, and be in a setting in which it is appropriate to focus on form. These
conditions do not apply for everyday speech. Examples:
* If he is at school: during the
break when he is talking with his friends.
* At home.
3. Comprehensible output (Swain
1985). To what extent do you think that output is important for students
acquiring a language? Discuss in relationship to Krashen's Input theory.
The Input Hypothesis states that an
important part for the teacher's planning time for a classroom based on the
principles of Second Language Acquisition will be devoted to strategies for
making the target language comprehensible to the student, but I think that
comprehensible output is also important if it is under pressure, because if the
message that the student tries to communicate is understood, he will, first of
all feel more confident, and at the same time he will acquire the
rule.
4. How do the findings in the field
of cognitive psychology support Krashen's affirmation that "hypotheses are
tested on a subconscious level"?
Because one of the most important
principles of cognitive psychology for the foreign language teacher is that
information is best learned and retained if it is made meaningful to
students.
5. How can you as a teacher make
sure the language presented will be comprehensible to the
students?
By engaging their students in
meaningful situations and making them full participants in the communication of
the classroom. They can work together with teachers across the curriculum to
help children understand what it is they need to learn and how their own
learning best takes place-to help children become aware of the process of
language acquisition and to enjoy their own progress.
6. Discuss Leslie Hart's definition
of learning. What are the dangers of simplified input?
Leslie Hart defines learning "as
the process of extracting meaningful patterns from the rich input of the
environment and shaping them into a program: a fixed sequence of behaviors for
accomplishing some intended objective".
From what has been said, simplified
input or presenting information in a carefully sequenced, prepatterned manner
represents a danger for the student because since each individual learning style
is different, the effort to prepattern the raw material of learning can be
helpful for only a limited member of students.
7. Within the categories of Whole
Language as presented by Edelsky 1992: beliefs about language, beliefs about
language development and beliefs about learning, choose two aspects of each and
discuss them in relation to your experience as a learner and future teacher.
Which aspects seem to be the most difficult to apply?
* Beliefs about
language:
* Language is a supersystem made up
of interdependent and inseparable subsystems. Learning the rules of the language
separately is not the same thing as learning language.
Since language is a supersystem, we
don't acquire the language by simply knowing the rules. First, examples have to
be presented and then the rule can be explained, in this way students can
understand the rule.
* Language is profoundly social,
its use always depends on a social context.
This aspect is difficult to apply
when students have the opportunity of studying a second language for an hour,
twice or three times a week and then they have no other contact with the
language.
* Beliefs about Language
Development
* Language is learned through
actual use to achieve personal purposes. It is not learned through drill and
practice for its own sake.
Again, in the case of being studied
twice a week, it is very difficult to learn it through actual use, although it
is a fact that it cannot be learned through drill and practice for its own
sake.
* Language learning is both natural
and social. It is natural in that it is a by-product of some important use to
which language is put. It is social in that occurs through social interaction
and develops in order to facilitate that intention.
This is very difficult to be
applied if it is not practiced with a certain regularity or if the students are
not in contact with native speakers.
* Beliefs about
learning
* Learning is best achieved through
direct involvement and personal experience. It is an active process in which
learners construct meanings rather than a passive activity in which teachers
transmit information.
To put in practice this, classes
have to be carefully planned, and something that is easier for some teachers is
just to transmit information and do a passive activity.
* It is the learner's purpose and
intentions that drive learning, not the teacher's goal for the
learner.
Sometimes teachers plan lessons
according to the syllabus of a book and do not take into account the learner's
purpose and intentions, and it may happen that the student is not quite
interested in the teacher's goal, so he is not motivated.
* Krashen,
Stephen & Tracy Terrell. 1983. The Natural Approach. Language Acquisition
in the Classroom. Hayward, California: Alemany Press. Chapter 1, 2
& 3.
Chapter One
1. What is the evidence Krashen
gives for considering the Natural Approach as a "traditional
approach"?
Krashen considers the Natural
Approach as a "traditional approach" because it is likely that for most people
the ability to communicate in another language is acquired through communicative
practice in real situations using the language for specific
functions.
2. The Audiolingual Method. What
were the components of the Army language course? Discuss the basic tenet of
audiolingualism.
It consisted typically of two
sessions-one in which situational-based dialogs were practiced and memorized,
followed by oral drills consisting of sentences illustrating the major syntactic
patterns and form classes of the language. These drill sessions were conducted
either by a linguist familiar with the language or by a native speaker trained
by a linguist. The dialogue-drill sessions were then followed by conversation
sessions with a native speaker, these were usually constructed around real life
situations. The classes were small, usually under ten persons, allowing for
sample opportunity to engage in communication experiences.
The basic tenet of audiolingualism
is the teaching of oral skills (listening and speaking) before reading and
writing, so the language is acquired through communicative practice in real
situations using the language for specific functions (Natural
Approach).
3. What are Krashen's criticisms to
the cognitive movement? Particularly in relation to this quote: "learned
competence cannot directly "become" acquired competence" (Krashen
1986:38)
The cognitive movement was a return
to grammar explanation followed by various sort of exercises to practice the
rule in question. According to Chaslain "the purpose of a cognitive exercise is
the comprehension of forms, the conscious learning of forms, and the conscious
selection of forms to fit the context".
Krashen thinks that language is
acquired through communicative practice in real situations and acquiring must be
subconscious; what is acquired is more lasting than what is
learned.
4. Discuss the following quotation
from Newmark & Reibel (The Natural Approach: 17) in relation to Krashen's
Natural Order Hypothesis.
(...) Systematic teaching of
structure (as in structure drills) imposes a formal rather than useful
organization of language material (...)"
Krashen's Natural Order Hypothesis
differs from Newmark & Reibel quotation, because the Natural Order
Hypothesis does not state that every acquirer will acquire grammatical
structures in the exact same order.
5. The silent period is considered
to be an active period. Why is this so? What is the acquirer building up?
(Krashen 1986:9).
The silent period is considered an
active period because the acquirer is constantly acquiring input, but he is not
able yet to output. He is building up competence by listening, via
comprehensible input. His first words in a second language are not the beginning
of his second language acquisition, rather, they are the result of the
comprehensible input he has received over the previous
months.
6. Why cannot spoken fluency be
taught directly but rather it emerges? Contrast cognitive psychology to
behaviorist principles.
Spoken fluency in second languages
is not taught directly. Rather, the ability to speak fluently and easily in a
second language emerges by itself after a sufficient amount of competence has
been acquired through input. It may
take some time before any real spoken fluency develops.
The study of the brain and
intensive work in cognitive psychology have resulted in a significant shift in
orientation away from the behaviorist principles. Rote learning, habit
formation, and observable outcomes are being replaced by an emphasis on
meaningfulness, metacognition and process. For the behavioral psychologist, the
student is considered to be a relatively passive subject, to be manipulated
through reinforcement techniques and drill. The cognitive psychologist, in
contrast, sees students as active participants in the learning situation,
controlling and shaping their own learning processes. In the behaviorist
classroom the student responds to stimuli and reinforcement, while in a
classroom based on cognitive psychology, the students' own internal motivation
drives the learning process.
Chapter Two
1. "Some individuals, it is
believed, have a special aptitude for second language study". (Krashen 1983:38)
Why is this debatable? What are the two different skills that Krashen associates
to acquisition and learning?
Having high aptitude makes you a
good learner but not necessarily a good acquirer. This may be an asset but it is
certainly not sufficient for success in second language acquisition. On the
other hand, a high aptitude does seem to predict success in a language classroom
which is grammar based on tests that demand grammatical analysis rather than
real communicative ability.
The two different skills that
Krashen associates to acquisition and learning are: that aptitude is related to
learning and attitude is related to acquisition.
2. The Role of First Language.
According to Krashen, why are Interferenced errors produced? Contrast the two
possible cures for this (drilling or more input).
Interferenced errors are produced
as a result of "falling back" on the first language when we lack a rule in our
second language.
The two possible cures for this are
drilling or more input. The behaviorist psychologist will use "drilling", the
cognitive psychologist will use "more input".
3. What are routines and patterns
useful for?
Routines and patterns are useful
for gaining more input and managing conversations.
4. Individual variation. Discuss
the three types of adult second language acquirers.
The three types of adult second
language acquirers are:
a) Monitor over-users are those who
monitor all the time. They are constantly checking their output with their
learned conscious knowledge of the second language. As a result, they speak
hesitantly, often self correct in the middle of utterances, and are so concerned
with correctness that they have difficulty speaking with any real
fluency.
Over-use may derive from learning
without acquisition. Another type may be related to
personality.
b) Monitor under-users are second
language performers who do not seem to use the monitor to any extent, even when
conditions encourage it. Under-users do not rely on conscious rules, but only on
acquisition.
c) The optimal monitor user uses
the monitor when it is appropriate, when it does not get in the way of
communication.
In normal conversation, where the
focus in on communication and where there is little time, the optimal user will
not be excessively concerned with applying conscious rules to performance. In
writing, and in planned speech, when there is time, optimal users will make
whatever corrections possible to raise the accuracy of their
output.
5. "(...) the ability to think
abstractly may be related to the ability to possess a mental representation of a
language, or a conscious grammar (...) Not everyone attains formal operations
and formal operations does not arrive at the same time in everyone". (footnote
42:51)
Discuss in relation to the role of
instructed grammar in the classroom.
The ability to think abstractly is
related to acquisition, each acquirer his "own time" to arrive at
conclusions.
Instructed grammar is related to
learning: the concrete thinker only arrives at abstraction from direct
experience with concrete objects.
6. Age differences. What are the
factors that differentiate children from adult acquisition? "The theory of
second language acquisition described here posits a basic uniformity in language
acquisition..." (Krashen 1983:44) What does "basic uniformity" refer
to?
Older acquirers may be superior in
initial rate of acquisition because they are able to get more comprehensible
input.
Factors:
* Older acquirers are better at
"managing conversations", or controlling the input directed at them and making
it comprehensible.
* Older acquirers have a great
ability to "beat the silent period" to produce in the second language using
structures that have not yet been acquired.
* Older acquirers have a greater
knowledge of the world. This greater extra-linguistic knowledge helps make input
comprehensible.
"Basic uniformity" refers to the
fact that we all acquire language in the same way, via comprehensible input.
This is not to say, however, that individual variation does not
exist.
7. Why is puberty considered a
turning point for language acquisition?
Puberty may be the turning point
for ultimate success in second language acquisition, and there is good reason to
hypothesize that it is at puberty that the affective filter increases in
strength dramatically. While affective variables do have an effect on second
language acquisition before puberty, they do not seem to be strong enough to
limit ultimate attainment in children: given sufficient exposure most children
reach native-like levels of competence in second language.
Chapter Three
1. What are the implications for
classroom practice of the Input Hypothesis?
The implications for the classroom
practice of the Input Hypothesis are:
* Comprehension: The requirements
that input be comprehensible has several interesting implications for language
practice. First, it implies that whatever helps comprehension is important.
Second, it implies that vocabulary is important. A third implication is that in
giving input, in talking to students, the teacher needs to be concerned
primarily with whether the students understand the
massage.
The discussion of age differences
and individual variations implies that comprehensible input will be the crucial
element of a language teaching program for all students, young and old, grammar
learners or not.
Another implication is that the
classroom may be a very good place for second language acquisition, especially
at the beginning and intermediate levels.
The affective filter hypothesis
along with the input hypothesis, implies that effective classroom input must be
interesting.
* Speaking: The input hypothesis
claims that the best way to teach speaking is to focus on listening (and
reading) and spoken fluency will emerge on its own.
Speaking is of course a primary
goal for most language students. It is also important in that it stimulates
conversation, which in turn will encourage more comprehensible
input.
* The role of grammar: Grammar
instruction has a limited role.
Only certain rules need be taught for optimal monitor use.
* Krashen,
Stephen. 1986. The Input Hypothesis: Issued and Applications. New York:
Longman. Chapters 1 & 2.
Chapter One
1. Age Differences: According to
Krashen what are the three strategies adults fall back to?
Older acquirers obtain more
comprehensible input in several ways. Their greater experience and knowledge of
the world helps make the input they hear and read more comprehensible. Also,
older acquirers can participate in conversations earlier than younger acquirers
can by utilizing the strategy of falling back on first language syntactic rules,
supplemented with second language vocabulary and repaired by the
monitor.
A third way older acquirers gain
more comprehensible input is via the superior skills in conversational
management.
2. Input and Exposure.
Discuss.
In cases where "exposure" really
entails comprehensible input, as in some school situations, there's a
relationship. Where exposure does not entail comprehensible input, as in the
case of an immigrant in a situation in which he can continue to use his first
language and uses his second language very little, we see a much weaker or no
relationship.
3. "Comprehensible subject matter
is language teaching" (Krashen 1986:16) Discuss.
Comprehensible subject matter is
language teaching because it does not focus on form but on the
message.
4. What is the importance of first
language in relation to Cummins (CALP) "cognitive academic language
proficiency"?
Solid subject-matter teaching in
the first language provides the child with "cognitive academic language
proficiency" (CALP), the ability to utilize language to learn and discuss
abstract ideas. This ability can be developed via any language and transfers to
any other; once a person can use language "intellectually", this ability can be
utilized in any other language the person subsequently
acquires.
5. Discuss the following quote:
"writing competence comes only from large amounts of self motivated reading for
pleasure and / or interest" (Krashen 1986: 19)
This is so because it was
discovered that instruction can give the student only the most obvious aspects
of the written language. This is confirmed by the failure of several studies to
show any clear relationship between the study of grammar and the ability to
write.
Chapter Two
1. How does acquisition occur for
the Output Hypothesis? Why is this hypothesis inappropriate to describe ill
formed versions in children's speech?
In the output hypothesis the
performer acquires rules by "trying them out" in communicative situations: when
he experiences communicative success, his hypothesis about the rule is
confirmed; if this happens often enough the rule is acquired. If the performer
fails to communicate using a given rule, his provisional hypothesis is
disconfirmed.
This hypothesis is inappropriate to
describe ill formed versions in children's speech because communicative pressure
and approval "cannot be the forces causing the child to relinquish immature
forms and adopt adult forms". Rather acquisition occurs because of "the
occasional mismatch between the child's theory of the structure of the language
and the data he receives", a view consistent with the Input
Hypothesis.
2. Where does the testing of
hypotheses take place according to the Input Hypothesis and the Output
Hypothesis respectively? (Krashen 1986:36)
According to the Input Hypothesis,
the testing of hypothesis takes place on a subconscious level. On the other
hand, according to the Output Hypothesis, it takes place on a conscious
level.
3. What are the characteristics of
the Output filter? (Krashen 1986:45)
The characteristics of the output
filter are:
* It is a device that attempts to
explain why second language users do not always perform their
competence.
* The Output filter prevents
acquired rules from being used in performance.
* There is a great focus on
communication.
* Accuracy increases when the focus
is off form, which indicates that the increase was not due to the conscious
monitor.
4. According to Krashen, what are
cases of "understanding without speaking" due to? (Krashen
1986:53)
The cases of "understanding without
speaking" are due to:
* Despite his claims, the
non-speaker is not fully competent in understanding the
language.
* The most likely explanation for
most non-speakers is the presence of a strong output filter, a hesitancy to
perform for psychological or affective reasons.
* In some cases, the non-speaker
may have considerable competence in his first language, but may encounter
negative evaluations of his competence due to the presence of occasional
developmental errors. This can have the effect of discouraging
production.
5. What are the possible causes for
Fossilization? (Krashen 1986:52)
The possible causes for
fossilization are:
* The result of inadequate
input.
* A strong affective
filter.
* A performer not performing his
competence.
* The acquisition of an imperfect
version of the target language.
6. Discuss the role of the language
teacher within the Natural Approach.
A language teacher is first of all
someone who can prevent messages of interest, help make them comprehensible, and
put students at ease; in short a communicator. The grammarian function of the
language teacher is very secondary.
7. Discuss the differences between
an international ESL student and an adult immigrant.
The differences
are:
* Many of these students will not
tolerate grammar study, students in elementary school do not have the cognitive
maturity to handle complex grammatical concepts, while many adult immigrants
have not had the necessary formal training.
* While some children will accept
"trivialized" instruction, the uneducated adult student often will
not.
* A great deal is at stake in ESL
both for LEP students and for adult immigrants. In many cases, the ESL class is
their only possible source of comprehensible input. Many LEP children of today
do not have the chance to use English outside the school, and many adult
immigrants live isolated from English speakers. For these people, the ESL class
must succeed if they are to have a chance of participating in American
life.

Congratulations to these hard-working students !
With this issue you will find four attachments. They are the transparencies that Prof. Claudia Alvarez , Class "C" Morning Shift uses for her classes for this first unit (Ficha de Cátedra 1). We are sure they will be very useful to all of you.
Well, as Bugs Bunny used to say "That´s all , folks"... for the time being, at least.
See you around!!
