This was a research and development study. The subject of the research was the teachers, principals, and supervisors. The data collecting instruments were questionnaires and observational sheet. The development process was carried out in 4 stages namely: (1) preliminary investigation; (2) planning development, validation; (3) tryout; (4) product finalization. The try out was perform-ed in 3 stages with the increasing number of participants for each stage. The learning process evaluation model was supported by instrument to assess lesson plans, learning implementation, and the implementation of learning outcome assessment. The content validity was assessed through focus group discussion (FGD). The construct validity was assessed by the factor analysis, and the reliabilities were estimated by the Intraclass Correlation Coefficient (ICC).

Abstract

The success in implementing the demand-driven approach in Vocational High Schools (VHS) can be realized by understanding the misalignment between graduate skill competency and workforce demand by the industry. This study aims at describing the precedence between the VHS graduates and the businesses/industrial sector (BS/IS) portraying from the regional potential perspectives. The research data was collected from documents, and survey forms distributed to BS/IS within the research population. The document analysis was employed to collect information on programs offered at VHS, existing VHS student enrollment, and the value of Gross Regional Domestic Product (GRDP) in studied provinces. An online survey was distributed to all VHS graduates and BS/IS employers. The content validity was carried out prior actual study to ensure the validity of the instrument. A descriptive analysis was performed to gather information pertaining to developed research objectives. The precedence of the academic programs with the GRDP was determined based on 5% of criteria differences. The results found that there is a misalignment between the academic programs and the VHS student's enrollment towards the region job potentials in each province in Indonesia. In addition, the research also found that the competency of VHS graduates related to theoretical knowledge, job characteristics, and workforce skills were at a moderate level. The implication of the study offers a salient notion on minimizing the precedence that occurs between the supply and demand in the form of graduates supply to the workforce and, at the same time, fulfilling the workforce requirements demand by the industries.

Abstract

The purpose of the study was to develop instruments for measuring teacher candidates' social competence in the Fourth Industrial Revolution (the fourth I.R.) era. The instrument was developed by referring to Indonesian Law Number 14 of 2005 concerning Teachers and Lecturers and the Regulation of the Minister of National Education Number 16 of 2007 to strengthen some special competence of teacher candidates in the fourth IR era. Limited instrument testing was carried out to 107 test subjects for the 6th-semester undergraduate education program at Yogyakarta State University, consisting of three study programs: Mathematics Education, Indonesian Language Education, and English Language Education study programs. The results of the content validity analysis of 30 instrument items obtained the Aiken V index between 0.61 - 0.93, with 29 items valid, and one invalid item. The construct validity analysis with EFA showed 25 valid items and five invalid items, with a KMO value of 0.504. The significance of Bartlett's test was p = 0.000. Meanwhile, the construct validity analysis with CFA showed the model fit, with a Chi-Square value = 290.35 (p 0.05). The reliability results show that the Cronbach’s Alpha coefficient is 0.40 (moderate category). This shows that the social competency assessment instruments for teacher candidates in the fourth IR era developed are feasible to use, with several improvements.

Abstract

Penelitian ini bertujuan untuk mengetahui banyaknya dimensi perangkat tes UAN Matematika tahun 2003, 2005, dan 2006. Dalam penelitian ini, yang dimaksud dengan dimensi adalah subkemampuan yang ada dalam kemampuan matematik. Penelitian ini bersifat deskriptif eksploratif. Data utama penelitian ini adalah respon siswa peserta Ujian Akhir Nasional yang ada di Provinsi D.I. Yogyakarta. Jumlah lembar jawaban siswa yang dianalisis sebanyak 2700 untuk tahun 2003, 3400 untuk tahun 2005, dan 3020 untuk tahun 2006. Respon siswa diambil dari SMP kelompok tinggi, sedang, dan rendah. Data dianalisis menggunakan teknik analisis faktor eksploratori, kemudian diestimasi banyaknya muatan dimensi/faktor dalam perangkat tes. Disimpulkan bahwa perangkat tes UAN Matematika tahun 2003, 2005, dan 2006 mengukur 3 dimensi subkemampuan yakni aljabar, geometri, dan pengukuran. Perangkat tes tersebut, hanya mampu menjelaskan sekitar 35% atau sekitar sepertiga varians kemampuan matematika siswa. Terkait dengan hal ini, pengembang tes UAN mata pelajaran matematika perlu mengusahakan agar menambah faktor dan variasi tingkat kesulitan butir tes, sehingga tes lebih dapat menjelaskan variansi kemampuan peserta tes. Sebaliknya bagi praktisi, sebaiknya memanfaatkan hasil penelitian ini untuk umpan balik dalam pembelajaran matematika di sekolah.Kata kunci: validasi dimensionalitas
