Abstract

The role of prosody and intonation in English phonology has significant implications for speech perception and production. These phonological processes influence how words are understood and articulated in English. Recent studies have shown that prosody and intonation play a crucial role in verbal communication. This article aims to investigate the importance of prosody and intonation in understanding and producing speech in English language learning intonation refers to the melodic pattern in speech that can change the meaning of a sentence. It is often used to convey emotions or to emphasize a message. On the other hand, prosody encompasses the patterns of pitch, stress, and duration in speech that impact word articulation and comprehension. Both work together to create accurate articulation and understanding of words in English this linguistic study underscores the importance of prosody and intonation in English language learning and elucidates how these two aspects influence speech perception and production. With a deep understanding of prosody and intonation, learners can enhance their ability to communicate in English more effectively and accurately.

Abstract

The cause of the low learning outcomes of students on matrix material is the lack of understanding of concepts and communication skills. A learning model that overcomes these problems is needed. The STAD type cooperative learning model can increase the interaction between students so that students can communicate and collaborate to understand matrix concepts. This class action research aims to improve students' learning outcomes on matrix material by applying the STAD type cooperative learning model in class XI-2 SMA Negeri 6 Surabaya. The data collection techniques used were observation, learning outcomes test, and documentation. The results showed that by applying the STAD type cooperative learning model can improve the learning outcomes of students of class XI-2 SMAN 6 Surabaya on matrix material. This is indicated by an increase in the value of learning outcomes and completeness of students after being given action in each cycle. There was an increase in learning outcomes by 39.39% from pre-cycle to cycle I and 54.54% from cycle I to cycle II. Learning completeness reached 54.54% in cycle I and 100% in cycle II.

Abstract

This research aims to describe the application of the Student Team Achievement Division (STAD) learning model in improving the learning outcomes of class XI-4 students at SMA Negeri 6 Surabaya, especially on the subject of vectors. The background to this research is strengthened by the fact that motivation to learn mathematics tends to be low, especially when studying complex material such as vectors. This is supported by initial observations which show that students often have difficulty understanding these concepts, which is reflected in the low learning outcomes, with a percentage of only 73%, and classical completeness of only 40%. This research is classroom action research carried out in two cycles. The research subjects consisted of 36 students. Data is collected through tests and observations. Data analysis was carried out using qualitative and quantitative descriptive techniques. The results in cycle 1 showed a significant improvement, with learning outcomes reaching 97% and classical completion increasing to 94%. In cycle 2, learning outcomes reached 98% and classical completion reached 100%. Thus, it can be concluded that the application of the STAD learning model is effective in improving the learning outcomes of class XI-4 students at SMA Negeri 6 Surabaya.

Abstract

In learning activities, motivation is an encouragement or process to direct students in achieving learning goals. The research was motivated by the very diverse problem of students' learning motivation in mathematics subjects in class XI TFLM-3 SMK Negeri 5 Surabaya. This can be seen from the results of the researcher's observations, where when they are about to start learning activities, many students still think that mathematics is less interesting and boring so that students are always less ready to start learning mathematics and the learning that was usually carried out by previous mathematics teachers was just learning. just lectures and assignments. This research aims to determine the increase in students' learning motivation in mathematics subjects through differentiated learning based on content. This research uses a type of Classroom Action Research (PTK) which consists of two cycles using data collection techniques in the form of questionnaires and observation. This questionnaire is used to determine learning satisfaction that motivates students after carrying out learning strategy treatment. The results of research using differentiated learning based on content show an increase in students' learning motivation from pre-cycle activities 63,8% to 73,1% in cycle I, then continued with cycle II. It shows that the presentation average of students' learning motivation in mathematics subjects is 83,2% From the results of this research it can be concluded that using differentiated learning based on content is successful in increasing students' learning motivation in mathematics subjects in class XI TFLM-3 SMK Negeri 5 Surabaya.

Abstract

This article discusses the importance of understanding heat convection in fluids in the context of physics and engineering. Using first order Simple Differential Equations (PDS), we can analyze the temperature distribution in a fluid over time and space in high detail. PDS allows modeling heat convection by considering parameters such as temperature differences and fluid flow velocity. Numerical methods are used to complete the PDS computationally, while data collection techniques through literature studies provide an in-depth understanding of relevant theories and previous findings. With the application of PDS and numerical methods, we can better understand and predict heat transfer in fluids, which has wide applications in engineering, biology, and physics. In conclusion, this article provides a comprehensive insight into the use of PDS in the analysis of heat convection in static and dynamic fluids, with a focus on mathematical and computational approaches to better understand this phenomenon.

Abstract

This work introduces a novel hybrid conjugate gradient (CG) technique for tackling unconstrained optimisation problems with improved efficiency and effectiveness. The parameter is computed as a convex combination of the standard conjugate gradient techniques using and . Our proposed method has shown that when using the strong Wolfe-line-search(SWC) under specific conditions, it achieves global theoretical convergence. In addition, the new hybrid CG approach has the ability to generate a search direction that moves downward with each iteration. The quantitative findings obtained by applying the recommended technique about 30 functions with varying dimensions clearly illustrate its effectiveness and potential.
