directly positively and significantly
correlated with student performance
(Alpacion et al., 2014). This is supported by
the results of research conducted by
(Ngussa & Mbuti, 2017) on high school
students in Arusha, Tanzania, who found
that students' positive attitudes can
improve students' performance in
mathematics. (Alpacion et al., 2014)
suggests that performance in Mathematics
can be improved by developing a positive
attitude towards the subject.
When students are involved in
mathematical activity, they will
continuously evaluate their learning
situation to keep them in line with their
personal goals (Hannula, 2002). The
process to activate and regulate thoughts,
behavior, and emotions in achieving a goal
is called self-regulation. When these goals
are related to learning, then the self-
regulation in question is self-regulation in
learning (self-regulated learning) (Mokhtar,
Tarmizi, Ayub, & Nawawi, 2013). The results
of research conducted by (Siregar, Solfitri,
& Siregar, 2021) found that students'
attitudes towards mathematics towards
self-regulation in learning have a
significant correlation with a contribution
of 58%.
Self-regulatory learning is seen as a
combination of skill and will. Skills refer to
the use of cognitive and metacognitive
strategies that include goal setting,
planning and organizing learning, self-
monitoring, self-evaluation, time
management, and resources. Meanwhile,
desire refers to an individual's motivational
orientation in terms of goals, values, and
expectations.
Previous research supports the
importance of self-regulation on academic
achievement. As has been pointed out by
Pintrich, Roeser, and De Groot, 1994; Chen,
2002. Students with high achievement use
more self-regulated learning strategies
than students with low achievement. In
addition, (Febrianela, 2013), of which
concluded that students who have high
self-regulation learning are followed by
high academic achievement.
Students' mathematical problem-
solving abilities are also influenced by
mastery goal orientation. The results of
experimental research conducted by
(Suwono, Pratiwi, Susanto, & Susilo, 2017)
provide treatment in the form of learning
using the mastery goal orientation learning
model. In this study, there are two groups
of classes, namely experimental and
control. In the experimental class,
treatment is given in the form of learning
by using the mastery goal orientation
learning model where mastery of learning
is the main point, and learning in the
control class is carried out conventionally
using lecture, question, and answer
methods, and giving assignments. Based
on the research data, it was found that the
average mathematical problem-solving
ability of students in learning using the
mastery goal orientation learning model
has increased compared to the control
group.
Therefore, variations in the level of
learning based on students' self-regulation
indicate a difference in the conditions of
motivation and strategies used by students
in completing their academic assignments.
In addition, the availability of a supportive
environment and precisely the actions
taken will bring a strong impetus to
