The enhancement of mathematical problem solving ability and self-confidence of students through problem based learning

Rahmi Ramadhani

Abstract


This paper reported result of a research attempted to analyze: the increase in student’s MPS and SC using problem-based learning; and to look interaction between students’ PMK and learning to increase student’s MPS and SC. This type of research was a quasi-experimental. The population of this research was all students in SMA Negeri 6 Medan. Then 33 students were chosen as the experimental class and 33 students in other class was chosen as a control class by using purposive sampling technique. The data in this study were analyzed using Two Ways ANOVA. The result of validity of student’s MPS test is 0,808. Both reability of test was 0.86. The result of this research were: (1) The enhancement of student’s MPS ability and SC using problem-based learning was higher than conventional learning; (2) There is no interaction between student’s PMK and learning on student’s MPS ability and SC.

Keywords

Strategies of Preservice Teachers to Negotiate English Teaching Practices at Remote Areas

STRATEGIES OF PRESERVICE TEACHERS TO NEGOTIATE ENGLISH TEACHING PRACTICES AT REMOTE AREAS Febi Puspitasari, Joko Nurkamto, Diah Kristina Abstract Poor condition and facilities of English Classroom at remote area promoted the negotiation of learning to solve problems. This narrative study is aimed at exposing strategies of preservice teachers of SM3T in the negotiation process of English learning. The research utilized diaries and interview transcripts of four teachers from Pidie Jaya and Sumba. Finding shows that teachers used interpersonal (IPS) and instructional strategies (IS) in the negotiation proccess. In Pidie Jaya, IPSs were speaking the local language and asking a help of the local people while ISs were learning groups and familiarizing learning activities. In Sumba, teachers used language adjustment, establishing rapport and informal communication as IPSs as well as buddy teaching and take-home tasks as ISs. It contributes to the cross-cultural approach in desig

The Effect of Change in Stock Ownership because of Stock Split on Stock Liquidity

PENGARUH PERUBAHAN KOMPOSISI KEPEMILIKAN SAHAM SEBAGAI AKIBAT STOCK SPLIT TERHADAP LIKUIDITAS SAHAM Nuri Lesmono Hidayah, Harits Noordin Abstract Abstract : The Effect of Change in Stock Ownership because of Stock Split  on Stock Liquidity .  This study aimed to determine the effect of the stock split on stock trading by considering stock ownership proportion in companies listed in the Indonesian Stock Exchange (IDX). This study hypotesized that stock ownership proportion and its change in later date affected stock liquidity. The population of this study was companies in the Indonesia Stock Exchange. The samples were 48 companies which conducted stock split in 2010-2015. The sample was selected by purposive sampling method. Hypotesis was tested by using paired sampelled t-test and regression analysis. The study found that stock split indeed affected stock trading. Stock split significantly affected Cumulative Abnormal Return (CAR) and trading activity, compared to data be
