Transition To Proof

The emerging of formal mathematical proof is an essential component in advanced undergraduate mathematics courses. Several colleges have transformed mathematics courses by facilitating undergraduate students to understand formal mathematical language and axiomatic structure. Nevertheless, college students face difficulties when they transition to proof construction in mathematics courses. Therefore, this descriptive-explorative study explores prospective teachers' mathematical proof in the second semester of their studies. There were 240 pre-service mathematics teachers at a state university in Surabaya, Indonesia, determined using the conventional method. Their responses were analyzed using a combination of Miyazaki and Moore methods. This method classified reasoning types (i.e., deductive and inductive) and types of difficulties experienced during the proving. The results conveyed that 62.5% of prospective teachers tended to prefer deductive reasoning, while the rest used inductive reasoning. Only 15.83% of the responses were identified as correct answers, while the other answers included errors on a proof construction. Another result portrayed that most prospective teachers (27.5%) experienced difficulties in using definitions for constructing proofs. This study suggested that the analytical framework of the Miyazaki-Moore method can be employed as a tool to help teachers identify students' proof reasoning types and difficulties in constructing the mathematical proof.

The ability to prove formal mathematics is an important ability that must be mastered by undergraduate prospective mathematics teachers. However, students who are prospective mathematics teachers have difficulty in constructing proof in mathematics courses. Therefore, this study aims to explore the tendency of mathematical proof methods for prospective mathematics teachers in second year lectures. The method used in this research is quantitative descriptive research. Participants in this study were 30 prospective mathematics teachers at a tertiary institution in Tuban, East Java. The research instrument is a simple task of compiling mathematical evidence. The results of the study were analyzed using the classification of types of proof by Miyazaki, namely classifying the types of deductive and inductive reasoning. The results showed that prospective mathematics teachers had a greater tendency to use deductive reasoning than using inductive reasoning. Type A proof is the most common type of proof. In addition, around 70% of prospective teachers still experience difficulties in compiling evidentiary tasks.

Abstract:Many researches revealed that many students have difficulties in constructing proofs. Based on our empirical data, we develop a quadrant model to describe students’ classification of proof result. The quadrant model classifies a students’ proof construction based on the result of mathematical thinking. The aim of this article is to describe a students’ comprehension of proof based on the quadrant model in order to give appropriate suggested learning. The research is an explorative research and was conducted on 26 students majored in mathematics education in public university in Banten province, Indonesia. The main instrument in explorative research was researcher itself. The support instruments are proving-task and interview guides. These instruments were validated from two lecturers in order to guarantee the quality of instruments.Based on the results, some appropriate learning activities should be designed to support the students’ characteristics from each quadrant, i.e: a hermeneutics approach, using the two-column form method, learning using worked-example, or using structural method. Keywords:proof, proving learning, undergraduate, quadrant model   MEMAHAMI STRATEGI PENGAJARAN PEMBUKTIAN MATEMATIS DI PERGURUAN TINGGI Abstrak: Banyakpeneliti pendidikan matematika menyatakan bahwa siswa mengalami kesulitan dalam mengonstruksi bukti.

The current study aims to determine prospective teachers’ opinions about WebQuest applications by both introducing them to the WebQuest teaching materials and obtaining their experiences in the WebQuest design process. This study employs phenomenology as a qualitative research approach. The study was conducted in the spring semester of the 2017-2018 academic year with the third year undergraduate students in the social studies education department of a state university in Ankara. Two different data collection tools, a Peer Evaluation Form and an Interview Form, were used. Content analysis was used to analyze the data obtained. According to the findings of the study, social studies preservice teachers think that teacher supervision of Webquest teaching activities is advantageous. Preservice teachers defined the specific principles of WebQuest teaching activities as a weak factor. Additionally, preservice teachers emphasized that WebQuest teaching activities are difficult to implement in environments where Internet and computer facilities are not available. Even though almost half of the participants stated that they wanted to include WebQuest teaching activities in their classes when they started the teaching profession, they expressed about their concerns.

Lassa fever is a zoonotic disease characterized by acute viral hemorrhagic fever, endemic in West Africa including Nigeria. The study assessed the knowledge and sources of information on Lassa fever infection among the undergraduate students of Ebonyi State University, Nigeria. This was a descriptive cross-sectional survey conducted among a sample of 389 students (18 years above). A self-administered questionnaire was used to collect data. Data were analyzed with SPSS (Version 20), and hypotheses were tested at p < .05 level of significance. Results showed that the majority of the students had good knowledge of Lassa fever description, 232 (60.75%); the signs and symptoms, 221 (57.9%); mode of transmission, 261 (68.41%); and preventive measures, 291 (76.13%). Radio, 23 (84.6%), and television, 307 (80.4%), were their major sources of information. Age ( p = .424), sex ( p = .082), and academic level ( p = .553) were not significant in the study, while faculty (social sciences; p = .000*) was strongly associated with the knowledge of Lassa fever. In conclusion, the overall knowledge of Lassa fever was good among students, though knowledge gaps were observed in the signs and symptoms. We recommend that health education on endemic diseases in the state be made a compulsory course as a general study (GST) in the university. Also, the internet, social media, and campus campaign be further used to educate and sensitize students on the effect of Lassa fever.

Intelligibility Ratings

As a result of a recent law passed in Ohio, a program was designed to improve the oral intelligibility of International Teaching Assistants at Bowling Green State University. To evaluate the efficacy of the training, naive undergraduate students were asked to evaluate the pre- and postrecorded speech samples of the international students, both in terms of intelligibility of the sample and the identification of the topic of the monologue. Analysis showed a significant improvement in the intelligibility ratings between pre- and posttraining samples. Further, the average number of correct subject matter identifications was shown to increase, while the average number of incorrect judgments decreased significantly from pre- to posttraining evaluations.

Career exploration reflects activities conducted to collect information about oneself and potential occupations to become self-aware and understand the job market. Career exploration guides the realization of career aspirations and is thus crucial for young adults. It helps the youth make appropriate career-relevant decisions. However, it is unknown whether career aspirations mediate the links between positive parenting and career exploration activities undertaken by urban third-year undergraduate students. This study aimed to bridge this gap in the literature, and to this end, a survey was administered to 125 third-year undergraduate students attending a state university in Semarang, Central Java. The Career Exploration Scale, Career Aspirations Scale, Positive Parenting Subscale, and questions on demographic characteristics were employed for data collection. Structural equation modeling demonstrated that career aspirations fully mediated the path between positive parenting and career exploration. The findings of this study underline the importance of career aspirations in translating the effects of positive parenting into specific career exploration activities undertaken by college students. Finally, suggestions based on the study results are offered for third-year undergraduate students, parents, and practitioners.

Advent of technology has caused growing interest in using computers to convert conventional paper and pencil-based testing (Henceforth PPT) into Computer-based testing (Henceforth CBT) in the field of education during last decades. This constant promulgation of computers to reshape the conventional tests into computerized format permeated the language assessment field in recent years. But, enjoying advantages of computers in language assessment raise the concerns of the effects that computerized mode of testing may have on CBT performance. Thus, this study investigated the score comparability of Vocabulary in Use test taken by 30 Iranian undergraduate students studying at a state university located in Chabahar region of Iran (CMU) to see whether scores from two administrations of testing mode were different. Therefore, two similar tests were administered to the male and female participants on two testing mode occasions with four weeks interval. Employing One-Way ANOVA statistical test to compare the mean scores and Pearson Correlation test to find the relationship between mode preference and performance revealed that two sets of scores were not different and gender difference was not also considered a variable that might affect performance on CBT. Based on the results, computerized version of the test can be considered a favorable alternative for the state undergraduate students in Iran.
