Abstract

In a progressively competitive global environment, organizations must continually reinvent their products and services to sustain their competitive advantage and achieve success in marketing management. Product innovation enables companies to generate additional value, distinguish themselves from rivals, and address the changing demands of the market. Concurrently, service innovation improves client experience, fortifies loyalty, and broadens market reach. This study seeks to investigate the degree to which product and service innovation impacts the efficacy of marketing management in internationally competitive markets. A quantitative methodology was utilized, employing survey data gathered from global corporations across diverse industry sectors. The analysis indicates a substantial association between innovation levels and the attainment of marketing objectives, with service innovation serving as a mediating role in the efficacy of product strategies. The research emphasizes the necessity of synchronizing innovation with marketing initiatives as a crucial element in creating durable competitive advantages. These findings provide strategic insights for marketing managers aiming to implement adaptable and innovative strategies to address the challenges posed by changing customer demands and global market dynamics.

Abstract

The low achievement in students' mathematics learning remains a persistent issue in education, primarily due to conventional teaching methods that fail to engage students actively. This study aims to examine the effect of the cooperative learning strategy, specifically the Teams Games Tournament (TGT) model, on the mathematics learning outcomes of eighth-grade students at SMP Negeri 1 Uwapa. The research employed a quantitative approach with a quasi-experimental method using a pretest-posttest control group design. The sample consisted of two purposively selected classes: one experimental group that received instruction through the TGT model and one control group taught using conventional methods. Research instruments included a validated multiple-choice test and observation sheets of student learning activities. The results revealed a significant improvement in the experimental group’s learning outcomes compared to the control group, with a posttest average score of 83.00 and a statistically significant difference according to the t-test (p < 0.05). Additionally, the TGT model enhanced student participation, motivation, and classroom interaction. These findings indicate that the TGT strategy effectively fosters an engaging learning environment and supports optimal student achievement. The implication of this research suggests that mathematics teachers are encouraged to implement the TGT model as an innovative teaching alternative, particularly in regions facing educational challenges.
