Induction Plays A Central Role In Performing generalization and abstraction, two important processes that are necessary and highly valued in all areas of mathematics (Kaput 1999; Mason 1996; Romberg and Kaput 1999; Schoenfeld and Arcavi 1988). From 2000 to 2004, at least 30,000 eighth-grade students in northern California were tested on algebra tasks that asked them to construct linear patterns of the form y = mx + b. The students were expected to generalize using explicitly defined functions, including selecting, converting flexibly among, and employing various representations for, the patterns. Five years of data collection and analysis of students' work have shown that only three-fourths of the eighth graders tested could successfully deal with particular cases of linear patterns in visual and tabular form, and that less than one-fifth could use algebra to express correct relationships or to generalize to an explicit, closed formula (Becker and Rivera 2004).

Abstract: This research aimed to investigate whether or not there were significant differences in reading comprehension and writing achievement between the eighth grade students of SMP Islam Az-Zahra 2 Palembang who were taught by using Literature-Based instruction and those who were not. This study used one of the quasi experimental designs: pretest-posttest design. The sample was selected purposively from the whole population based on their reading comprehension scores. Forty six eighth graders were selected as the sample and equally divided into experimental and control groups. Pretest and posttest were given to both groups.  Using paired sample statistics,  the results of the experimental group showed that the students’ reading comprehension and writing achievement ? significantly improved. Furthermore, the result of the independent t-test showed that with mean difference of reading comprehension was 8.609, t value 11.111(p<0.05). Moreover, the mean difference of writing achievement was 6.8043, t value 10.478 (p<0.05).   Keywords:   Literature-based instruction, reading                     comprehension and writing achievement.

The interplay between culture and technology is dynamic. Since ancient times, science has had a major impact on people, and people have determined the general direction of science progress. In this way, there is mutual influence between society and science. Socioscientific issues have emerged as a result of the interaction process between science and society. In this context, it was aimed to examine eighth grade students' attitudes towards socioscientific issues. The study was conducted with 136 eighth grade students studying in a city in the Central Anatolia region of Turkey in the 2018-2019 academic year. Quantitative data collection and analysis methods were used in this study, which aimed to examine the secondary school students’ attitudes towards socioscientific issues. “The Attitudes towards Socioscientific Issues Scale (ATSIS) " was used as data collection tool in the study. According to the findings of the factorial ANOVA test; it was determined that eighth grade students' showed positive attitude on socioscientific issues. While students had positive attitudes related to interest and usefulness of SSI, they also had neither positive nor negative attitudes related to interest and usefulness of SSI. In addition, it was observed that the general attitude levels about socioscientific issues and the mean scores of interest and usefulness, liking and anxiety sub-dimensions did not differentiate according to gender. Based on the findings, the importance of socioscientific issues was emphasized and recommendations were made to program makers, researchers and practitioners on teaching.

Trends in International Mathematics and Science Study (TIMSS) is an international comparative study that has been implemented by the International Association for the Evaluation of Educational Achievement (IEA) since 1995. This proposed study is aimed to identify the affective factors contributing to eighth graders' science achievement in TIMSS among Southeast Asian and East Asian countries. The freely-downloadable secondary data were analyzed using IEA's International Database (IDB) Analyzer (version 4.0) for TIMSS, a plug-in for SPSS. TIMSS uses an imputation methodology, involving plausible values, to report student performance. This study found that students' views on engaging teaching in science (BSBGESL) were negatively and significantly contributed to eighth-grade students' science achievement in Thailand, Singapore, Chinese Taipei, and Hong Kong SAR. Students Like Learning Science (BSBGSLS) were positively and significantly contributed to eighth-grade students' science achievement in Malaysia, Singapore, Thailand, Hong Kong SAR, and Chinese Taipei. Students Confident in Science (BSBGSCS) were positively and significantly contributed to eighth-grade students' science achievement in Korea, Japan, Chinese Taipei, Hong Kong, Thailand, and Singapore. Students Value Science (BSBGSVS) was positively and significantly contributed to eighth-grade students' science achievement in Japan, Korea, Thailand, Chinese Taipei, Singapore, and Malaysia. Based on the research findings, policy recommendations were made to the Malaysian Ministry of Education to boost Malaysian eighth graders' science performance in the forthcoming TIMSS studies.

The paper considers the main results and some educational implications of the TIMSS 2003 assessment conducted in Serbia in the fields of the science achievement of Serbian eighth grade students and the science curriculum context of their achievement. There were 4264 students in the sample. It was confirmed that Serbian eighth graders had made average scale score of 468 points in the science, and with this achievement they are placed in the zone of the top of low international benchmarking level, very close to the point of intermediate benchmark. The average science achievement of the Serbian eighth graders is somewhat below the general international science achievement. The best results were achieved in the science content domain of "chemistry", and the lower results in the content domain of "environmental science". Across the defined science cognitive domains, it was confirmed that the Serbian students had achieved the best results in cognitive domain of "factual knowledge" and weaker results in "reasoning and analysis". The achieved results raise many questions about contents of the science curriculum in Serbia, its overall quality and basic characteristics of its implementation. These results can be eligibly used to improve the science curricula and teaching in Serbian primary school. .

This study belongs to a pre experimental research. The population was the eighth grade students of MTs. Mu’allimat NW Kelayu consisting of two classes. However the present researcher just took one class as sample there were 20 students as the experimental class. To get the data, the present researcher used research instrument namely written test.The result of data analyze, the present researcher found out the result rtest was 0.52 and r tablewas 0.38 with df = 5% from the total of sample was twenty students. It means rtest was higher than rtable (0.52> 0.38). So that, the present researcher concluded alternative hypothesis (Ha) was accepted, and null hypothesis (Ho) was rejected. It means that there was effect of email on students‟ writing skillsatthe eighth graders of MTs. Mu’allimat NW Kelayu in the school year2017-2018
