Article excerpt

Abstract

A good-quality teacher may determines a good-quality learning, thus good-quality students will be the results. In order to have a good-quality learning, a lot of strategies and methods can be adopted. The objective of this research is to improve students' ability in determining the rules of a numeric sequence and analysing the effectiveness of the implementation of the n-term to determine the rule of a number. A research classroom method administered at the State Islamic Junior High School Malang-Indonesia is adopted. The results show that the implementation of the n term formula may improve the students' ability in determining the numeric sequence in the State Islamic Junior High School Malang-Indonesia. Some suggestions are offered: a) observation of learning activities should always be made to obtain inputs on the implementation; b) learning innovations should always be made to base on facts obtained through observation; c) the results of this study may be used for reference for further development in learning numeric sequences that enable students to be more interested in studying mathematics.

Keywords: good-quality learning, numerical sequence, the n term formula

1. Introduction

Each learning approach may be used as teacher guide in designing learning activities as efforts to help students attain their learning objectives. The learning approach is a systematic procedure as a teacher guide in designing their learning activities to reach their predetermined learning objectives (Sakdiyah, 2006; Utomo, 2007; Nurdin, 2007).

A learning strategy adopted cannot be said to the best strategy for all learning materials, but for a certain material. (Arends, 1997; Noraini, 2005). In determining an appropriate strategy, it is the teacher who determines, since he is a very important part in the learning activities and the main factor in the process of improving the quality of education (Fasli & Dedi, 2001; Sakdiyah, 2006), besides, students, curriculum, facilities and infrastructure factors (Bafadal, 2004; In'am, 2012). A teacher is a human element that heavily determines the success of education that is why it can be stated that the improvement of school quality is dependent upon teacher professionalism (Bafadal, 2004; In'am, 2012). A good-quality teacher may commit a quality learning, implying that good-quality students will be the result (Wahyudin, 2007; In'am, 2012), and to reach such a quality learning, a lot of strategies and approached may be adopted.

There are various factors influencing the success in learning mathematics. A successful teacher of mathematics should be able to cope with and to solve any learning problems in the class intelligently (Nik Aziz, 2008; I Made, 2008). There are some matters to pay attention in mathematics learning namely: a) students are actively involved in their learning and are learning mathematics meaningfully accompanied with working and thinking and doing their learning to learn; b) any new information should be related to other information, so that it will unite into a scheme students possess to make any comprehension of complex information happen; c) learning is oriented into investigation and discovery which is principally problem solving in nature (Hudoyo, 2005; Noraini, 2005).

On the basis of observation the researchers have made, students are often difficult to determine the n term formula from the numerical sequence with certain patterns. The patterns and rules prevailed between one numerical sequence and another might be different, since the numerical sequence cannot be categorized into an arithmetic sequence.

From the description above, it is necessary to change the implementation of the learning activities and to make researches in order to solve the problem. Therefore, the following two research questions were addressed in this study:

1) How is the implementation of the n-term forluma to improve the ability in determining the rule of numeric sequence of the students in State Islamic Junior High School Malang-Indonesia? …
