Abstract

Facing technology's rapid development, teachers must continue to learn and innovate. Teachers must be able to lead, innovate and make changes to develop the quality of their schools. On an independent initiative, a teacher can make himself a reflective and innovative teacher. One of the efforts that can be made is through mentoring activities in conducting learning analysis with TBLA. To reflect on learning, the teacher must first understand the principles of reflection, analyze the reflection results and interpret them. The analysis of respondents from mathematics teachers in Lampung Province (February-March 2022) revealed that teachers' understanding of learning reflection and its benefits was still low. Therefore, mentoring activities in learning analysis with TBLA for mathematics teachers were carried out. Based on the implementation results, the service activities showed an increase in the understanding and skills of the participating teachers regarding the analysis of learning reflection with TBLA. This is indicated by the significant average score of the n-gain theory of 0.41 (medium improvement category). One teacher from 15 participating teachers has carried out practice/assistance as an example of its application. However, the practice carried out by model teachers is the first step in creating reflective and innovative teachers. Teachers who can analyze situations in the learning process can open up problems during learning so that teachers get input for improving their learning. Therefore, increasing the knowledge and skills of the participating teachers regarding analysis and reflection of learning with TBLA has to be improved even more.

Abstract

Education 4.0 strongly promotes the development of communication, collaboration, critical thinking, and creativity (4C) skills among students. Consequently, it is crucial for mathematics teachers to integrate activities that facilitate the cultivation of these skills. However, the scarcity of resources, such as recommended instructional activities, poses a challenge for mathematics teachers striving to effectively impart 4C skills through problem-solving methods. This research aims to develop a set of teaching activities designed to enhance the delivery of 4C skills through problem-solving methods, thereby supporting mathematics teachers in improving their pedagogical strategies. Utilizing the modified nominal group technique (mNGT), the study engaged 11 experts from diverse fields, including mathematics education, pedagogy, curriculum development, and primary and secondary education. Data collection was conducted through expert discussions between January 2024 and February 2024. Descriptive statistics (percentages) were employed to analyze the data, prioritizing and ranking each teaching activity. The findings identified 19 pertinent teaching activities that emphasize 4C skills through problem-solving methods. The highest-ranked activity was motivating students to explore various learning resources, including information and communication technology (ICT) tools (98%), while guiding students through problem-solving questions received the lowest ranking (75%). In conclusion, the comprehensive list of teaching activities provides a valuable guide for mathematics teachers to effectively incorporate 4C skills into their instructional practices.

Abstract

Mathematical reflective thinking skills and self-concept are essential aspects of 21st-century learning to address global challenges. This study analyzes the effect of Project-Based Learning (PjBL) on students' mathematical reflective thinking skills and self-concept. The experimental research involved 75 tenth-grade students in Bandar Lampung using a posttest control group design. Data were collected through mathematical reflective thinking skills tests and self-concept questionnaires and analyzed using parametric and non-parametric statistical tests. The results showed that the implementation of PjBL did not significantly affect students' mathematical reflective thinking skills and self-concept compared to conventional learning. However, the indicators of mathematical reflective thinking skills achievement in the PjBL class were higher. This study implies the need for a longer implementation of PjBL to achieve significant results and its potential contribution to developing students' collaboration, creativity, and social skills as part of holistic learning.
