The Effectiveness of the Problem Solving Strategy and the Scientific Approach to Students' Mathematical Capabilities in High Order Thinking Skills.

Abstract: The purpose of this study was to find out more effective teaching among problem solving strategy with a scientific approach to students’ mathematical abilities in high order thinking skills. This quasi experimental study used non-equivalent pretest-posttest control group design. The experimental group was students who were taught with problem solving strategy, and the control group was students who were taught with the scientific approach. The number of participants for the experimental group, n = 138, and for the control group, n = 139 from the 10th grade of public and private high schools in Medan-Indonesia. Based on the hypothesis testing of the study, the results showed that learning through problem solving strategy was more effective than the scientific approach to students’ mathematical abilities in communication, creativity, problem solving, and mathematical reasoning.

Impact of Heuristic Strategy on Students’ Mathematics Ability in High Order Thinking

Abstract: The purpose of this study is to determine the impact of heuristic strategy on students’ mathematical abilities in high order thinking. This descriptive research uses a correlation design. The population of this study were all second-grade public and private high school students representing schools from eight districts in North Sumatra province, and samples (N = 257) were taken randomly. Based on linear regression analysis through analysis of variance (ANOVA) results obtained that heuristic strategy has a very strong influence on students ‘mathematical abilities in high order thinking, and partially heuristic strategies affect students’ ability in (1) understanding of concepts, (2) creativity, (3) mathematical communication, (4) problem solving, and (5) reasoning ability.

The Effect of Skimming Method to Improve Students’ Ability in Reading Comprehension on Narrative Text.

Abstract: This research deals with the effect of using skimming method in teaching reading comprehension smk negeri 2 pematangsiantar on narrative text. The problem of this research are “what is the students’ ability in reading without using skimming method at Grade XI students’ of SMK N.2 Pematangsiantar. What is the students’ ability in reading by using skimming method at Grade XI students’ of SMK N.2”. The purpose of this research are to find out the students’ ability in reading without using skimming method at grade XI students in SMK N 2 Pematangsiantar on reading narrative text, to find out the the students ability in reading by using skimming method to the skill of grade XI students in SMK N 2 Pematangsiantar on reading narrative text. To answer the problem the researchers uses theories: Micklukey and Jefferies (2007), Grellet (2000), Milter (2001), Jhon and Dara (2005), David Nunan (1991), Douglas Newton (2000), Douglas Brown (2003), Rae Pica (2000), Roger Brown (1973), Ronald Carter (1998), Scoot Thornburry (2002), Wilga Rivers (1987), Diane Larsen (1990), Judi Willis (2008), Jack and Theodore (1986). The research design is a quantitative research. As an experimental research, it aims to know the effect of the technique that given and apply whether it influences to the object or no. In this research in collecting the data the researcher has to do three steps, they are pre-test, treatment, post-test. The researchers find out that the effect of using skimming method can increase the students’ skill in reading of narrative text. It can be proven from the test of students’ score in posttest of experimental class which the treatment the researchers did the treatment by using skimming method. By using skimming method, the students can increase their ability in reading of narrative text.

Pengaruh Model Pembelajaran Inkuiri Terbimbing dengan Multi Representasi terhadap Keterampilan Proses Sains dan Penguasaan Konsep IPA

Abstract: Tujuan dari penelitian ini mengetahui model pengaruh pembelajaran inkuiri terbimbing dengan multi representations terhadap keterampilan proses sains dan penguasaan konsep IPA siswa SMP Swasta Surya Pematangsiantar. Penelitian kuasi eksperimen ini menggunakan post-test only control group design dengan melibatkan siswa kelas IX yang dipilih secara simple random sampling. Kelas eksperimen menggunakan pembelajaran inkuri terbimbing dengan multi representasi dan kelas kontrol menggunakan pembelajaran inkuiri terbimbing. Hasil penelitian menunjukkan keterampilan proses sains siswa kelas eksperimen tidak berbeda dengan siswa kelas kontrol, sementara penguasaan konsep IPA siswa kelas eksperimen berbeda dari siswa kelas kontrol, dan keterampilan proses sains siswa berkorelasi positif dengan penguasaan konsep IPA

An Analysis of Ideational Metafunction on News Jakarta Post about Some Good Covid-19 Related News

Abstract: This research intended to find out components of transitive system used on news Jakarta post about some good Covid-19 related news. Therefore, the researcher formulated a question as the problem as follows: “What are components of transitive system used on news Jakarta post about some good Covid-19 related news?” The researcher used qualitative design because data are collected by using documents in form of word and a procedure of systematic analysis of content text (words, phrase, documents, etc.), analysis content by qualitative enable researchers to understand the text by grouping words that have same meaning into categories. The research finding showed that component of transitivity system. There are three transitive system namely participants, process, and circumstances. First, participants found namely goal, actor, sayer, senser, verbiage, value, token carrier, attribute, behaver, client, recipient, phenomenon, and receiver with calculate is 177 participants, the highest participant is actor (26.55%). The second process found material, mental, verbal, behavioral, relational with calculate is 103 processes, the highest process is material (44.67%). The third, circumstance found extent, locution, contingency, manner, matter, and role, with calculates are 80 times. The highest circumstance is extents or time (30 %).
