The Influnce E-Commerce Shopee Strategic Online Purchasing Decision Generation Z in Panam Pekanbaru

E-Commerce competition is becoming increasingly attractive in the world of online shopping, it requires a special strategy in order to compete competitively, E Commerce Shoope performs a Twin Date Event Strategy, Flash Sale, and Free Shipping Cost, Population in this study amounts to 100 people using purposive sampling methods.  Based on the results of this study, Twins Date Events, Flash Sale and Free Shipping have influenced purchasing decisions both partially and simultaneously. The results of the Determination Coefficient show that the magnitude of the influence of both free variables together on the bound variable is 54.7% and the remaining 45.3% is another variable not studied. Future research could delve into these unexplored variables to provide a more comprehensive understanding of what drives purchasing decisions in the e-commerce sector. Understanding these additional factors could further assist e-commerce platforms like Shoope in refining their marketing strategies, ensuring they not only attract but also retain customers in a highly competitive market.  

The Role of Concrete Materials in Developing Childrens Understanding of the Properties of Quadrilaterals

The purpose of the study was to try to understand how concrete materials can help to develop primary school children's understanding of quadrilaterals. Concrete materials for the purpose of the study refers to all materials and physical objects that can be seen, touched, felt and manipulated for mathematical learning. I worked with four boys (ages 9-11) of mixed ability from a private school that works in close collaboration with IED. I tutored them for one hour outside of their classroom situation. This teaching was done four times a week for seven weeks using at least nine different kinds of concrete material to teach about the sides, angles and diagonals of the parallelogram family of quadrilaterals (square, rhombus, rectangle and parallelogram). My role was dual in nature, that of a researcher as well as a teacher. After determining the needs of the students by an initial activity I designed materials to suit the learning needs of the children. Data was collected with methods suited to the qualitative paradigm of research, i.e., by field notes, audio taping the teaching/learning sessions and collection of samples of students' work and reflections. My own reflections guided the evolution of the research process. My biggest learning was that the role of the teacher is the key factor for effective teaching with concrete materials. The best of materials will not work unless the teacher takes the role of a facilitator, an assessor, a decision maker and a tailor. Concrete materials sometimes succeeded and sometimes did not succeed in developing an understanding of the concept in the children's minds, but in both cases played a key role in students' learning. The materials helped to develop students' mathematical language, encouraged discussion (both teacher-student and student-student), sharpened the ability of the students to question and probe their own and their peers understanding and also unveiled the alternate frameworks that the students harboured about the geometrical concepts under study. Important insights were gained into how children learn the different properties of the four quadrilaterals. For example, all students considered a rhombus to be a "tilted square”, the use of a flexiquad helped the students to learn to differentiate between the two. This study also discusses some of the possibilities and challenges of using concrete materials in the Math classroom and its implications for the teacher or a teacher educator.
