Bachelors Degree

Experience

I am a young, energetic science teacher who has been teaching and tutoring biology, physics, and chemistry for the last four years. i don't believe science needs to be a dreaded, monotonous subject and love to apply what i teach to the real world. this makes lessons far more interesting and keeps learners engaged

Tutoring Approach

I adjust my teaching style to the needs of my students. If a student needs help preparing for a specific exam we will focus on that but otherwise I like to be a bit more creative with my lessons. I enjoy using written materials, videos, and discussions to master a topic.

Education

2nd Bachelors

Experience

I believe in the potential of each and every child and aim is to discover what each student is capable of and bring out the potential in each and every one of them. emphasizing on each student individually, paying careful attention to their academic ability, personality and how they solve the worksheets in order to provide effective support to ensure learning at a level that is “just-right” for each individual. i ensure to acknowledge the growth of each student without comparison to others, while offering praise and encouragement. at the same time, cooperate closely with parents in monitoring the growth of each student to maximized successful learning with a strong sense of achievement.

Tutoring Approach

Worksheets are structured to allow progression in small steps, enabling each student to advance smoothly from easy to difficult problems and ultimately toward studying advanced high school level materials on their own. Worksheets are designed to allow students to advance through self-learning. Nonetheless, there are times when students encounter problems that they don’t understand or are unable to solve on their own. I will encourage self solving problem tactics through guidance. In doing so, students enjoy a sense of achievement and are able to master new material independently.

Bachelors in Aerospace Engineering

Experience

I am an international student living in thailand having recently accomplished my bachelors in aerospace engineering with a first honors degree from chulalongkorn university. i am looking to teach students to obtain teaching experience and to also share the knowledge that i have obtained. i am academically skilled having good knowledge in mathematics and physics. i have taught igcse students before so i have a few months of experience. additionally, i have also voluntarily taught english at my university to students in the thai department.

Tutoring Approach

I have an adaptive teaching style which is dependent on the student. I approach the lesson plan with a simple objective: Make it work for the student. The class begins with a review of the study plan for the hour followed by the learning of concepts. Once the concept is clear, I allow the student to solve problems based on the concept learned and then evaluate the comprehension of the student. The pacing is then adjusted based on the comprehension of the student with the goal of the student always kept in mind (the deadline for a test for example). Homeworks are provided to encourage practice and to strengthen understanding. Additionally, I use Media to strengthen concepts in physics to improve remembrance.
