Abstract

Klein-4 or Klein-V group is a group with four elements including identity. The binary operation on Klein-4 group will produce identitiy if operated to it self and produce another non-identity element if operated to another non-identity element. The focus of this paper is to explain the principle of Klein-4 group on Domino card and also find all complete possible elements. Domino card is a set of 28 cards which the surface of each card divided in two identic boxes contain combination of dots as pattern. The final part of this research is to find out all possible combination of cards which can be used as elements of a Klein-4 groups.

Abstract

Prospective science teachers must master pedagogical knowledge (PK) and content knowledge (CK), commonly referred to as Pedagogical Content Knowledge (PCK), before entering the teaching profession. PCK is essential professional knowledge that supports effective science teaching. This study aims to analyze the PCK readiness of prospective science teachers in Indonesia and the Philippines, with a focus on the CK and PK competencies required for teaching in the ASEAN context. The study employed a mixed-methods approach. Survey data were collected from 110 prospective science teachers undertaking field teaching practice in schools in Indonesia and the Philippines. In addition, in-depth interviews were conducted with 12 participants, consisting of six prospective teachers from each country. The data focused on participants’ understanding and preparation related to pedagogical skills and science subject matter. The results indicate that the overall PCK level of prospective science teachers falls within the “moderately ready” category. However, the proportion of participants classified as “ready” remains relatively low, ranging from 44.9% to 58.5%. These findings suggest a need for strengthening both PK and CK among prospective science teachers. Enhancing PK can be achieved through additional pedagogical education and targeted training programs to improve teaching skills. Meanwhile, improving CK can be supported by providing more specialized science content courses aligned with school curricula prior to teaching practice. PCK readiness plays a crucial role in supporting sustainable development. Beyond integrating pedagogy and content, PCK enables prospective teachers to effectively convey scientific concepts related to sustainability issues: climate change, natural resource conservation, environmentally friendly technologies.
