PENDIDIKAN NILAI, BUDAYA DAN KARAKTER DALAM PEMBELAJARAN MATEMATIKA DASAR PADA SD/MI

Value, culture and character education is an effort to improve the quality of the process and learning outcomes that lead to the formation of the character of students who are characterized by national culture. These cultural values and characters are the pride of the nation and make the nation known by other nations as a nation that has a distinctive Indonesian character. Education has a function in developing cultural values and past achievements into a proud element for the present and future life so that it becomes a strong foundation for national character. Value education, culture and national character are important points that must emerge in the learning process in the classroom. Integration of the three in the learning process, especially mathematics learning, is intended as a process of introducing values and culture, facilitating the acquisition of awareness of the importance of values and culture in the behavior of students through daily learning processes that take place both inside and outside the classroom on all math subjects. Thus, mathematics learning activities, in addition to making students master competencies (material taught in mathematics) are targeted, also to make students know, care, and internalize cultural and character values in everyday behavior

IMPROVING HIGH SCHOOL MATHEMATICS TEACHER ABILITY IN MAKING E-MODULE IN PADANG PANJANG CITY

Technological development is very possible to use in learning activities for improving the quality of education. Much research has strongly advocated the use and integration of technology in the learning process. One form of utilization of these technologies is the use of E-Modules. E-modules in learning are teaching materials used in assisting learning activities in the form of soft-files that are operated through computers. Interactive e-learning module motivates students to learn more spiritually, actively and independently that can be used by teachers in the learning process. E-Modules allow students to learn not only in the classroom but wherever they are. However, there are many teachers who cannot create or design e-modules. In West Sumatra itself, especially the city of Padang Panjang, e-modules are unknown by teachers. Based on the results of interviews with math subject teachers who are also chairmen of the High School Mathematics MGMP in Padang Panjang City, in general the teachers in the city of Padang Panjang do not know about e-modules and really need training or guidance on e-modules themselves to improve quality their learning in class. Based on this, it was felt necessary to implement an activity program to improve the ability of mathematics teachers in desaining E-Modules in the Padang Panjang city with the partners of Mathematics MGMP. This activity will be facilitated by the IT team who will explain the ins and outs of the E-Module so that technical knowledge about e-modules can be properly controlled by partners. In addition to the IT team this program also involves a team of Mathematics experts who will evaluate the modules designed by teachers during the implementation of the activities so that the quality of modules that can be used by students can be maintained. The mechanism for implementing PKM activities is carried out using action research steps which consist of 4 (four) stages, namely: planning, action, observation and evaluation, and reflection. The implementation of this activity creates e-learning modules that can be designed by subject teachers, especially mathematics.

Who is more motivated to learn? The roles of family background and teacher-student interaction in motivating student learning

Scholars generally agree that family socioeconomic status significantly influences student engagement and motivation in school learning. Yet, teachers are key adults who play an equally important role in determining student experiences through daily interactions in the classroom. This study asks how family and teachers together shape student motivation to learn. Using data from the China Education Panel Survey (CEPS), we examine the roles of teachers vis-a-vis parents in fostering students’ motivation to learn Math, Chinese, and English subjects. We find that both family background and student-teacher interactions are related to students’ learning motivation. However, student-teacher interactions fully mediate the association of family background and student motivation to learn Math and Chinese, whereas student interest in learning English remains independently related to family background. Importantly, we show that students with strong learning motivation have high academic performance. Our findings reveal a hidden mechanism of the reproduction of class inequality through the school system and suggest that not only parents but teachers also play a nontrivial role in shaping educational inequality. We discuss the implications of our findings on educational stratification in Chinese society.

The current study aimed at identifying the effect of applying analytical rubrics on learning achievement of addition and subtract fractional operations at levels of knowledge and application for 5th grade primary students in Ibn Qutaiba Primary School, in Makkah city. The sample consists of 85 students who are equally divided into two groups: the experimental group uses the analytical rubric, and the other is the controlled group where the analytical rubrics is not employed at all. The results show that there is a statistically significant difference between the experimental group and the controlled group in terms of the average scores of the students results in the achievement test. This significant difference, at the levels of knowledge and application, statistically goes to the experimental group which utilizes the analytical rubrics. Based on the finding of the study, the researcher recommends that there is a need to raise the awareness of the significance of the analytical rubrics among teachers and all those who concern with education in general. This could be executed through various ways such as the educational and electronic publications, including analytical rubric in preparation programs at colleges of educations for Math teachers and educate them on how to use it in teaching and assessing Math subject, and finally train practice teachers on the mechanism of preparing and using analytical rubrics in teaching Math and assess to what extent it is learnt.

When STEM and STEAM Really mean ABC: A Democratic Critique of “Anything but Civics” Schools

In this article, we discuss the rise of what we call ABC schools: Anything but Civics. These are STEM/STEAM schools and programs that orient their focus around teaching science, technology, engineering, and math subjects (sometimes adding the arts). We trouble the tendency toward individualistic and narrowly economic orientations in these programs and discuss strategies for reinfusing a democratic mission and vision into education (both within and beyond STEM/STEAM schools). In making our argument, we discuss competing purposes for education, argue for why today’s context calls for democratic visions of education to take precedence, discuss the growth of STEM education along with problematic myths about STEM, identify the hidden curriculum of STEM (to support individualistic/corporate/capitalist visions for the purposes of schooling) and suggest both practical and idealistic paths forward.

Linking Experiential Workshops and Increased STEM Interest Among First- and Second-Generation Latino Youth

Extension outreach professionals are searching for new methods to target the growing population of Latino students. Oklahoma State University faculty in the Animal Science department and the 4-H Youth Development program partnered to sponsor a 4-H STEM Institute designed to promote science, technology, engineering, and math to Latino students in the Unidos Se Puede program. The STEM Institute was designed to introduce the Latino youth to college life and STEM based career opportunities. The program was evaluated utilizing the 4-H Common Measures Science instruments. The results indicate a positive impact on the youth’s perception of STEM as a career option. The students increase in self-efficacy predicts the students will increase their persistence in the subjects of science and math (Simpkins, Davis-Kean, & Eccles, 2006). Increased persistence in science and math leads to increased success in post secondary STEM studies and occupations.

The implications of evaluation and educational policy reforms on English secondary school music education

Neoliberalism in government thought and action has taken a very specific route in England. Building on a policy research grounding, and subjecting governmental and ministerial utterances to careful consideration, this article discusses the ways in which the specifically English situation has evolved. It reports that government has been carefully manipulative in terms of meeting its objectives and of finding ways in which to privilege science, technology, engineering, and math subjects in the curriculum of schools, while at the same time downplaying the place and role of the arts. It describes how school performance measures, the English Baccalaureate and Progress 8, are utilized to achieve the desired ends. The means by which governmental policies find their outworkings in the day-to-day lived experiences of schools are discussed, and the pernicious effects of these policies on the operationalizing of arts curricula generally, and music education in particular, are instantiated and discussed.

METODE KUANTITATIF DENGAN PENDEKATAN KLASIK PADA APLIKASI ANALISIS BUTIR SOAL SEBAGAI MEDIA EVALUASI PENENTUAN SOAL YANG BERKUALITAS

This paper discusses the design of an application for the analysis on items using quantitative method with the classical approach as a media evaluation for teachers in determining the quality of questions in an exam or a test. The classical approach is the process of examining each item in the test based on the students' answers for calculating the Difficulty Index (Dif I) and the Discrimination Index (DI) of each question. The Difficulty Index is the ratio between the number of students who answered an item (or a question) correctly and the total number of students who participated in the test. The Discrimination Index is a measure of how well an item (or a question) is able to distinguish between clever students and students who are less clever. The data used in this research was obtained from class VII SMPN 10 (Junior High School) Makassar, especially on math (subject). The data includes math questions that have been tested, the answers given bythe students of class VII, and the data about the students. The results of the item analysis will provide information whether a question can be accepted, corrected or to be rejected. The application generated from this research is expected to be able to offer assistance for the teacher in performing item analysis. The results of the analysis can be used to help teachers in compiling more qualified questions in the future.

Gender achievement gaps among Chinese middle school students and the role of teachers’ gender

Based on a nationally representative data of middle school students from China, this paper intends to document gender performance gaps among middle school students in China and the role of teachers. gender in either reducing or perpetuating such gaps. We find substantial gender academic achievement gaps in favor of girls in all of the three main subject areas, although the sizes of the gaps are substantially smaller in math than in literacy. Exploiting the fact that middle school students in China are randomly assigned to classes, we then examine the impact of student-teacher gender match not only on academic performance, but also on students. self-perceived ability in each subject area and self-perceived interactions with the teacher teaching that subject. Our results suggest that teacher gender has little impact on boys. In contrast, having a female teacher noticeably improves girls. self-reported student-teacher interactions, self-perceived ability, and academic performance, although the effect is only robust and persists over time in the subject of math.
