Strategies for encouraging students to persist on challenging tasks: some insights from work in classrooms.
Roche, Anne ; Clarke, Doug ; Sullivan, Peter 等
As part of a project called Encouraging Persistence Maintaining
Challenge (EPMC), we have been working with teachers in the upper
primary years, jointly planning lessons involving challenging tasks, and
exploring strategies which teachers might adopt to increase student
persistence on these tasks.
Most curriculum guidelines in mathematics education stress the need
for teachers to extend students' thinking, and to pose substantial,
realistic and open-ended problems (e.g., City, Elmore, Fiarman &
Teitel, 2009). The intention is to develop productive habits of mind in
mathematics, such as persisting, thinking flexibly, applying past
knowledge to new situations, and taking responsible risks (Costa &
Kallick, 2000). Yet in previous projects we have found that teachers
seemed reluctant to pose challenging tasks to students, and students
seemed to resist engaging with those tasks and exerted both passive and
active pressure on teachers to over-explain tasks or to pose simpler
ones (Sullivan, Clarke & Clarke, 2013).
Pogrow (1988) warned that by protecting the self-image of
under-achieving students through providing them only "simple, dull
material" (p. 84), teachers limit the development of
self-confidence. He maintained that it is only through success on
complex tasks that are valued by the students and teachers that such
students can achieve confidence in their abilities. There will be an
inevitable period of struggle while students begin to grapple with
problems, but Pogrow asserted that this "controlled
floundering" is essential for students to begin to think at higher
levels.

In sharing our experiences in the EPMC project, and the insights
which have emerged so far, we draw upon a small three-lesson design
experiment (e.g., Kelly, 2003) at Years 5 and 6. The mathematical focus
of the three lessons was on interpreting maps, including understanding
and applying a coordinate system to specify locations, using map scales
to find the distances between landmarks, using knowledge of compass
bearings to locate landmarks, and using and interpreting keys or
legends.
Determining the distances between landmarks requires an
understanding of the scale provided on the map and the use of
proportional reasoning. In the tasks discussed below, this could be
determined in several ways, such as by counting grid squares in a
horizontal or vertical direction between landmarks, by using some
indirect measure such as a ruler to measure the distance in a straight
line on the page and convert this measure to an actual distance on the
map, or using a piece of string to determine the distance of a
non-straight path on the page and converting this length to an actual
distance on the map. In particular, the use of map scale within the
lessons discussed in this article was anticipated to be the most
challenging part for which persistence would therefore be required.
There has been some research on student use of coordinate systems.
Blades and Spencer (1989) noted that many young children by the age of
four can use a coordinate reference system, and by age six are
successful in tasks requiring an understanding of grid references.
However, Battista (2007) also suggested that having students locate
points is not enough; students must also analyse distances between
points and determine these distances from coordinates. Sullivan et al.
(2013), in discussing a task involving map scale, suggest that students
in the middle grades are rarely asked to either create and/ or use a
scale.
The setting and data collection We believe that a carefully
designed sequence of tasks has the potential to help learners to develop
important mathematical ideas (Simon & Tzur, 2004). The three lessons
were developed and piloted in other schools by the first author, prior
to their use in Holy Spirit Primary School (North Ringwood, Victoria).
At Holy Spirit, the first author taught the lessons to one Grade 5/6
class, while another teacher, Marianne, observed. Marianne taught the
lessons to her own students the following day, while the two authors
observed, collecting video and audio data and field notes on aspects of
challenge and teacher behaviours that might assist student persistence.
This two-part approach was taken so that Marianne would be comfortable
with the mathematical intentions of the lesson and have a sense of how
the lesson might play out before teaching it to her own class.
It is the lessons taught by Marianne which form the basis of the
study. The authors prepared a written assessment, focusing on relevant
content. This assessment was administered two weeks before the teaching
sequence, one week after the three lessons, and then six weeks after the
teaching had been completed.
The three lessons
In this section, we give a brief overview of the three lessons.

Lesson 1: Sandy Point Fun Run (Roche, 2013)
In this activity, students create a fun run (see a student work
sample in Figure 1). The instructions to the students are that it must
begin at the gate of Sandy Point Primary School, and end at the same
gate (marked on the map). It must be between 1 and 2 kilometres long and
must stop at exactly five out of the eleven checkpoints marked on the
map. The students record on a separate table the progressive distance
along the route, and the name and location of the checkpoints,
(including the grid coordinates, the street name and the side of the
street on which it is located; e.g., east side of Main Street). The
scale on the map indicates that each square is 50 metres wide, meaning
that 2 centimetres on the map is 50 metres in reality.

Lesson 2: Waratah State Forest
In this activity, the students complete a map of a State Forest,
where only four landmarks are provided: the lookout, the walking track,
the car park and the picnic area (see Figure 2). The key has missing
icons for four other landmarks: the lake, the waterfall, Clancy's
tree and the camping ground. These missing icons must be designed by the
students and added to the key and the appropriate place on the map. From
the lookout, there is a circular sign on which there are directions and
distances to the missing landmarks which provide the information
students need to locate them. The students are asked to place the
circular sign (a laminated circle, 9.5 cm in diameter) onto the map in
the appropriate orientation. Students also answer questions about their
completed map such as: What direction is the camping ground from the
lookout? Approximately what distance is it from the picnic area to the
waterfall along the track?

Lesson 3: Treasure Island
In this activity, the students recreate a map of a 'treasure
island'. Grid coordinates of the landmarks are provided (some
partial, see Figure 3), as well as a story of two pirates and their
journey in search of treasure.
These provide important information from which the students
recreate the map of the island, outline the path the pirates take, and
determine the location of the hidden treasure (see Figure 4). Along the
way, the students use compass directions and map scale to determine the
direction and distances between landmarks.
One of the greatest challenges for students in Treasure Island was
the openness of the task. Some students struggled to come to terms
initially with the fact that the location of Polly's Reef, for
example, was not fixed, and that various decisions they made (e.g., the
size of the lake) might affect the locations of various other landmarks.
What did we learn about the tasks, the level of challenge, and
teacher actions to encourage persistence?
The EPMC project has involved four different schools to date, and
we have developed a list of suggested strategies drawing upon what the
research team and teachers are learning together across the schools. A
detailed list can be found in Sullivan, Clarke, Michels, Mornane and
Roche (2012). There were, however, two particular aspects which emerged
strongly from the three lessons outlined above, and these are now
discussed.
* Tasks are chosen which have the potential to engage students in
worthwhile, challenging and interesting mathematics.
All three lessons were rated by the teacher and students in surveys
and interviews as engaging but challenging. Struggle is important for
students if real learning is to take place. As Hiebert and Grouws (2007)
noted, "we use the word struggle to mean that students expend
effort to make sense of mathematics, to figure something out that is not
immediately apparent. We do not use struggle to mean needless
frustration or extreme levels of challenge created by nonsensical or
overly difficult problems" (p. 387). When interviewed, the focus
students highlighted challenges such as using the scale to determine
actual distances, measuring distances along a curve, and dealing with
the openness of some tasks (e.g., determining the location of the
treasure in Treasure Island which could depend upon assumptions made
from earlier clues). The teacher and researchers noticed challenges such
as the mechanics of using a ruler appropriately and conversion of units.
* The ways of workingare explained to the students, including the
type of thinking in which they are expected to engage and what they
might later report to the class.
If students are to attack problems with confidence and to persist,
it is important that they are clear about what is expected of them. With
the class on the mat and engaging visuals to 'hook' the
students, the teacher gave a brief summary of the work ahead, the time
allocated to it, and expected outputs, particularly in relation to what
would be recorded. The teacher made comments such as: "When you
come back, I will be really interested in how you used the scale to work
out the distance, because that's the challenging part." The
students then commenced work, usually in pairs, with the expectations
clear in their minds. During interviews, the classroom teacher
highlighted that explaining the ways of working was one that she was
specifically working to improve in her teaching.
[FIGURE 4 OMITTED]
In audiotaped interviews with Marianne after each lesson, there
were two recurring themes: her greater emphasis on holding back and
listening to students more, and the struggles in which her students were
involved. She was finding that holding back meant that she was less
likely to intervene inappropriately, and was more likely to really
understand her students' thinking. Although while she noticed
students were struggling, it was a positive struggle where students were
wrestling with important ideas, while not being discouraged.
Some encouraging assessment data
As mentioned earlier, students completed a pre-test of relevant
content, and then the same test as a post-test and a delayed (six weeks)
post-test. There were 16 items (three involving grid coordinates, five
involving compass directions, and eight involving scale). We were most
interested in the improvement on the two items which proved most
challenging on the pre-test. The first of these involved determining the
distance travelled between three towns (from A to B to C to A, see
Figure 5) using a scale. Only four out of 26 students were successful on
the pre-test, but this increased to 10 on the post-test.
[FIGURE 5 OMITTED]
The second task involved writing or drawing a scale for the map
shown in Figure 6, given the actual distance (500 m) between the
flagpole and the lookout.
[FIGURE 6 OMITTED]
Before the three lessons, only three students out of 26 correctly
drew a scale, with six redrawing part of the map (see examples in Figure
7) and four leaving the item blank.
[FIGURE 7 OMITTED]
However, on the post-test, 14 students drew a correct scale (see
examples in Figure 8) and no one redrew part of the map or left the item
blank.
[FIGURE 8 OMITTED]
We were most encouraged that the work on challenging tasks yielded
considerable improvement on the most difficult items.
Conclusion
For worthwhile learning in mathematics, students need
mathematically appropriate, engaging and challenging tasks. At the same
time, the decisions which the teacher makes (in planning, and 'on
the run') can make a considerable difference in how the task plays
out, the level of persistence shown by students, and the resulting
learning, cognitively and affectively.
