The math course used in this research is taught in a constructivist manner. A constructivist instructional-based mathematics course was designed to utilize hands-on activities, manipulatives, problem-solving approaches, and cooperative learning environment. In the beginning of the semester, an instrument, Utley Geometry Attitude Scales (UGAS), used to collect data. At the end of the semester, the UGAS was re-administered to the two classes by the researcher. The t-test results indicated that there was a statistically significant difference of the UGAS mean score between the preand posttest (p = 0.001), at the 0.01 significance level. Using  = 0.01 as the pre-study determined level of testing, there was sufficient evidence to reject the null hypothesis, regarding differences in the measure of pre-service elementary school teachers’ attitudes toward geometry collected at the beginning and end of the constructivist instructional methods based on mathematics course. Furthermore, the t-test results indicated that there was a statistically significant difference of the UGAS sub-scale mean score between the preand posttest (p = 0.001), at the 0.01 significance level. Using  = 0.01 as the pre-study determined level of testing, students demonstrated the significant change in UGAS sub-scales. The results clearly show an improved attitude toward geometry. This study demonstrated that constructivist instructional-based mathematics course had improved the attitude toward geometry. The National Council of Teachers of Mathematics (NCTM) has established goals involving students’ dispositions toward mathematics that include value, self-confidence, and interest. By studying pre-service elementary teachers’ attitudes toward geometry and the experiences that have played a crucial role in the development of these attitudes, teacher educators can use this information to develop training programs aimed at improving these attitudes.","PeriodicalId":159185,"journal":{"name":"US-China education review","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122896720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This detachment from nature results in a lowering in the sense of ownership of the land and its resources, and subsequently, results in less motivation to conserve it. In order to reverse such behaviours and attitudes, a new programme termed “Lifelong Learning through Nature (LLN)” was devised. This study is an analysis of the LLN programme and its potential of making links among outdoor learning, fieldwork, and education for sustainable development. These results shed light on the effectiveness of the programme in influencing knowledge and attitudes, and in turn, lead to formulate a way forward in the programme’s evolution. Outdoor education is an essential element of education for sustainable development (ESD), which is key to address the current situation for a sustainable future. The data is collected through an extended questionnaire from a number of different schools in the Maltese islands, which is analysed through Statistic Package for Social Science (SPSS). The results reveal a great sense of detachment in the young students, and eventually, a greater sense of pointlessness in the older students. This study reveals that the field visit does have an influential role in the knowledge and attitudes of school children towards nature. This study continues to uphold the vision that outdoor education should be considered as a main activity, which involves and results in ESD. In response to these findings, a model illustrating the emerging links between the field visit programme and various factors is presented. This paper directly illustrates how university research in teamwork with non-governmental organisations can impact the local community. Also, the study will be useful to anyone who is interested in carrying out effective programs and research in the links between ESD and outdoor education.","PeriodicalId":159185,"journal":{"name":"US-China education review","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132513945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, it is in charge of providing counseling in the self-assessment processes of undergraduate and postgraduate programs aimed at obtaining the accreditation of academic excellence required by the National Accreditation System for Higher Education (SINAES) in Costa Rica. On February 21 in 2017, the computer engineering career received an accreditation certificate for the following: (a) diploma and bachelor’s in computer engineering; (b) bachelor’s degree (licenciatura) in computer engineering; (c) bachelor’s degree (licenciatura) in computer science and software quality; (d) bachelor’s degree (licenciatura) in computer science and project management; and (e) bachelor’s degree (licenciatura) in computer engineering and web application development. The career as a whole was awarded in an official ceremony held in the central facilities of the UNED, where the authorities participated. Accreditation by SINAES was done according to Agreement-National Accreditation Council (CAN) -393-2016, in session on October 14, 2016 through Act 1089-2016 and ratified on November 4, 2016. SINAES accreditation is paradoxical for the Computer engineering career. The self-evaluation processese stablished by an accrediting agency to publicly certify that the career has quality criteria represent an end and a beginning as well. It is the end of a a strenuous period of facing difficult work processes of the career staff accompanied by the IGESCA adviser and receiving external evaluation of three specialists in the field (academic pairs), two international professionals and a national one, who verify that the career complies with the criteria and standards of the SINAES Accreditation Manual and recommend its accreditation, so that it can subsequently be approved by the SINAES Council, and thus, receive the accreditation certificate. It is the beginning of a new stage: the fulfillment of improvement actions incorporated in the commitment resulting from the self-evaluation, to turn the weaknesses into improvement opportunities and to maintain tested standards for the purpose of continuous improvement. This is why it is important to evaluate the self-assessment of the degree courses, in this case, the computer engineering career, always in search of quality, validity, reliability, and continuous improvement. It is here where the term meta-evaluation is referred both as a higher level and a new concept of institutional evaluation.","PeriodicalId":159185,"journal":{"name":"US-China education review","volume":"351 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122646131","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research is a qualitative research using the interpretative paradigm. The method applied in the study is the interpretative phenomenological analyses (IPA). The results of the study indicate that the aspect of one’s belief plays a decisive role in selecting information regarding the information of Greater Jakarta Province general election 2017. What is more, information only has limites roles in adding knowledge to strengthen the belief of the informants of the candidates to be elected. Belief has decisive roles in selecting information and reflects the strenthening of one’s belief for his/her political choice. In this case, belief is used to support the choice already possessed. Within the scope of political communication, it is often times confirmed that the vote for a candidate will lead a person to a process of information selection to support his/her choice and not to weaken it. When I do the selecting of information, support from the group does not really play a role. I have my own principle either to select (accept) or refuse information of the pair of candidates (governor and deputy governor). Apart form that, members of my group are neutral and they have nothing to do with politics or the general election. In our group, we do not want to interfere in others’ affairs, especially when it comes to the group members’ personal choice. Choices are up to ourslves. It is up to everyone to read the news about canditate pair A or candidate pair B. In this matter, the group does not interfere.

Conrad’s Africa as an enigmatic dark spot is replicated in the works of Achebe, thereby, debunking popular critical polarizations of the texts. However, while Conrad’s narrative engages a double indictment of representations of darkness in the consciousness of both Europe and Africa, Achebe simply surrenders to a one-sided condemnation of African traditions and acquiesces to western narratives. Ultimately, while Conrad’s narrative leaves an echo of double reverberation in the heart of the reader, Achebe’s provide closure in his evident installation of western ideologies and their institutions. Conrad’s influence on Achebe is manifestly evident in Things Fall Apart (1958) and Arrow of God (1964). The fact that Achebe disavows this is an issue in this … I see them contrapuntally, that is, as figures whose writing travels across temporal, cultural and ideological boundaries in unforeseen ways to emerge as part of a new ensemble along with later history and subsequent art.","PeriodicalId":159185,"journal":{"name":"US-China education review","volume":"206 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131807617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This has led to young people being pathologised and marginalised by the adult society.

They are known as an explicit manner of motivating learners to correct their original erroneous utterance without the expert providing the learner with the correct form or any explanations of errors. Furthermore, when prompts (e.g., repetition of learners’ error) are added to the elicitations, the combination is prone to encourage learners to produce their own target-like output by serving to assist learners in the transition of declarative knowledge to procedural knowledge. Unfortunately, despite the existing structures of research available, there is still a great area of concern inside and outside the classroom with professionals unbearably providing ill-advised protocols that include, most often than not, giving away the correct answer before the learner has been given an opportunity to reformulate their utterance. Likewise, this current empirical study made up of 34 intermediate level Spanish students in a middle size university, elicitations with prompts were suggested to be more effective in promoting the production of modified output (MO) when compared to no feedback and elicitations alone (without prompts). The full and partial repairs formed by the learners were indicative of a more target-like production in regards to the higher rate of reformulations, regardless of the tense and aspect in the target structures.","PeriodicalId":159185,"journal":{"name":"US-China education review","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127685749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Teacher shortages in many schools and poor student results continued to be the order of the day. When the government of Zimbabwe introduced the education capacity development programme for teachers in 2014, Zimbabwe Open University (ZOU), as the only university mandated to offer open and distance learning (ODL), introduced within its Faculty of Arts and Education, and the Department of Teacher Development. Would ZOU be able to produce equally-trained or even better teachers than other colleges or universities? In light of this background, this study sought to investigate the challenges faced by ZOU students and their mentors and supervisors during teaching practice (TP). Of the postgraduate diploma in education (PGDE) intake 13 students who had come to the Midlands Regional Campus to write their examinations, 50 were randomly sampled and asked to fill in open-ended questionnaires. Twelve mentors stationed at some schools in Gokwe District where TP visits were carried out and 10 TP supervisors at the Midlands Regional Campus filled in similar questionnaires. By quantifying similar responses, emerging patterns and themes were noted. The major conclusions were that the TP period was too short, school based mentors needed training, lecturers spent more time on rushed assessment than supervision and ZOU had to provide sufficient human and material resources and logistics in order to enhance viability and sustainability of TP mentoring and supervision. It is recommended that the challenges faced and solutions offered by the respondents be used to initiate further debate and insights towards coming up with a new teacher-training model for ODL.","PeriodicalId":159185,"journal":{"name":"US-China education review","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121281199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
