Reflection
Handling a math class with teenage students approaching high school is a challenge yet it
is also a great opportunity. From this experience, I noticed that learners at this age need
motivation to pursue professional training in higher learning. The use of self-regulated
approaches and group techniques is evident in this unit development (Schunk & Zimmerman,
2012). Classroom diversity is also inevitable because students come from different backgrounds.
Contemporary learning involves the use of multicultural techniques. Digital communication as
part of modern classroom techniques is also a necessity. This discussion identifies the
development of learner’s skills for a better outcome and the use of pedagogical strategies for
professional practices.
Motivational factors
Intrinsic and external motivation influences the learner’s fascination with subjects. I used
personal motivation and a positive group influence for this unit. In order to give math a sense of
relevance, I look a focus of these lesson tactics:
Adding value to the topic of discussion
Capturing the student interest
Engaging their participation
Enhancing their performance
Simplification of concepts through multiple activities
Although intrinsic motivation matured through self-efforts, it became better with the
introduction of reward reinforcement. The use of assessment tests encouraged personal initiatives
through study and exercises. However, students at this level felt rewarded through an
encouragement a focus on the subject as a professional subject. In the unit, practical examples

from real life situation such as financial management and shopping activities awaken the
student’s passion. On the other hand, external motivation comes from participation in class
(Watt, et al., 2012). Children from different socioeconomic backgrounds require access to equal
learning opportunities. The curriculum approach encourages equal opportunities for multiracial,
gender and social groups (Acara, 2009).
Skills outcome
The assessment of learning principles using professional practices in this case abides by
the curriculum needs. This shapes the Math lesson content with relevancy and contemporary
ideas. The figure below is an example of the digital classroom models. This model encourages
the use of internet videos in Math Lessons. Other models for tasks and performance evaluation
are in Appendix.

Math 2A 15
Literacy, numeracy and ICT
Understanding the students inspired the development of individual abilities. The choice
of learning material from ICT resources was based on the following:
Student feedback for strong and weak points
Student anticipation to discover more about the lessons
Applicability of the work in the lessons and the next sections
Existing lesson challenges such as complex analysis and concepts
Scaffolding
Research into math strategies include a solution plan that supports the development of
competencies through sucompetencies (Blum, Kolter, & Schukajlow, 2015). This shaped my
choice of the Australian strand and sub strand approaches to learning Math. By encouraging
learners to focus on higher learning through continuous education, the student develops a
desire to achieve more. Through student engagement, and digital technology I made the
topics simpler for a better grasp. Students in year 11-12 need a deeper understanding of
different approaches in Math. A curriculum focus on key topics places an emphasis on the
basics and provides exposure for the next level (NSW, 2017). The socio-cultural learning
theory and pedagogical theories used relate to the teaching area. Focusing on Math as part of
life while meeting the syllabus expectations hits the target (Jonassen & Land, 2012).
Task based Learning
Through continuation of learning and a wider scope of student activities, this syllabus
encouraged the teacher to know the student and their learning difficulties. Learners who
exhibit challenges in Multiplication may also experience challenges in lessons such as

division. Progressive development starts with an understanding of the level of the learners in
order to bring out standard achievement and consolidate levels of literacy. Covering the
general capabilities such as thinking skills, IT skills and creativity is important for self-
management and group work activities. I used cultural objects like beads for learning in order
to support social competencies and content development. Engaging the student in
participatory learning and task based approaches optimizes skill development (National
Numeracy Learning, 2018).
Conclusion
The experience I obtained in the development of this unit highlights effective
teaching methods for professional practice with feedback from assessment. I used engaging
Stage 6 Syllabus that comprises of rigorous activities. Based on the complexities of advanced
Math for learners approaching high school, I used a unit with sub lessons. This simplified the
subject through learning principles that work. It also looked at the curriculum needs through
professional development. Engaging the student through multiple learning resources calls for
effective implementation strategies that prioritize on the educational policies while
incorporating the socio-cultural perspective. Shaping the student’s attitude towards learning
Mathematics determined the learner’s motivation, improved understanding and overall
outcome. Pedagogical strategies in lesson plans focus on units that optimize on the
development of the students skills.
