Abstract

The aim of this research was to examine the level validation of student worksheets based on science process skills with the theme of acid rain for class VII SMP. This research was an RnD (Research and development) research using a development model by Thiagarajan which was adapted into 3D (define, design and develop). The data collection instrument used was a questionnaire in the form of an assessment instrument for student worksheets. The assessment of the student worksheets consists of the feasibility of content, the feasibility of presentation, the feasibility of science process skills, the feasibility of language and the feasibility of graphics. The results of the assessment carried out by material expert validators, media expert validators and practitioner expert validators on student worksheets based on science process skills on the theme of acid rain for class VII junior high school, namely 90.27% for content feasibility, 92.7% for presentation feasibility, 90.62% for science process skills feasibility, 88.63% for language feasibility and 84,61 for graphics feasibility. So the percentage of the final score for the assessment of the student worksheets is 88.47% with very valid criteria, it means that the student worksheets is suitable for use in science learning.

Abstract

By linking the domains of science studies, the 2013 curriculum emphasizes integrated science study. Scientific learning is more than just memorizing information and concepts; it must be shown via experiments that allow students to apply science process skills. As part of the production of instructional materials, science process skills are taught. Such as LKPD, which is built on the predict, observe, and explain principle (POE). The goal of this study is to learn more about the creation process and degree of validation of POE-based LKPD training PPP on environmental conservation topics in grade VII SMP. The study was conducted utilizing a 3-D version of the 4-D Research and Development technique, particularly the Define, Design, and Develop stages. A validation questionnaire was filled out by two material expert lecturers, two media experts, and two junior high school science teacher practitioners for the study's instrument. The results showed that the development process used 3D development and that the POE-based LKPD had a level of validity of 90% for material experts with a very valid category, 72% for media experts with a valid category, and 90.5% for junior high school science teachers with a very valid category. The POE-based LKPD may be evaluated in scientific learning to develop science process skills, based on the recapitulation of the validation findings; all validators received an average percentage value of 84% in the extremely valid category.

Abstract

At the junior hight school level in carrying out the science learning process, the teacher only applies the lecture method which only provides theory and does not carry put pratical so that students alack interest in learning. This result in the low active participation of students in learning activities and learning outcomes are less satisfactory. As an alternative to overcome partical problems and foster interest in learning, a virtual laboratory based on guided inquiry was developed with the theme of objects around us. The virtual laboratory is validated by experts, namely material experts, media and pratitioners to obtain validity data used in the learning process. The research method used is Research and Development  with reference to the development model of Thiagarajan (1974) which was modified in 3 stage. The instruments used are interview sheets and validation sheets. The results of the validity level of guided inquiry-based virtual laboratory with the theme of objects around us obtainded an average value of 92,67% with the ‘very valid’.  Based on this assessment, a guided inquiry-based virtual laboratory with the theme of objects around us in fostering interest in learning for students can be applied in learning activities.

Abstract

Learning activities that lead to creative thinking skills have not been fully implemented.. Creative thinking skills can be trained by developing teaching materials in the form of E-Worksheet which is able to train students' reasoning abilities. The open-ended problem approach is able to direct students to solve problems in various ways. So that the E-Worksheet based on open ended problems is able to give students the freedom to describe the results of creative analysis to solve problems. The purpose of this study is to measure the level of validity of the E-Worksheet based on the open ended problem of the global warming theme to train the creative thinking skills of grade VII students. The method used is research and development or Research and Development (R&D) with the 4D research and development model by Thiagarajan (1975) which is modified as needed by being limited to the development stage until the product validation test. The instrument used is a validation questionnaire sheet that has been tested by instrument experts to determine the level of validity of the developed E-Worksheet. Data were analyzed descriptively quantitatively and qualitatively. The results showed that the level of validity of the E-LKPD based on the open ended problem of the global warming theme obtained a value of 89,1% with the "very valid" category. The results of the assessment are based on the average value of material experts, media experts, and expert practitioners.

Abstract

Kinerja guru dalam proses belajar mengajar sains merupakan indikator penting mencapai tujuan pendidikan. Faktor-fakor yang diduga mempengaruhi peningkatan kinerja guru dalam pembelajaran sains antara lain disiplin kerja dan motivasi kerja seorang guru. Hal inilah yang melatarbelakangi penelitian terkait rendahnya kinerja guru dalam pembelajaran sains di SMKN se Kab. Pekalongan. Penelitian ini bertujuan menganalisa pengaruh disiplin kerja (X1) terhadap kinerja pembelajaran sains (Y), motivasi kerja (X2) terhadap kinerja pembelajaran sains (Y), dan pengaruh keduanya secara bersama terhadap kinerja pembelajaran sains (Y) di SMKN se Kab. Pekalongan. Penelitian ini merupakan penelitian kuantitatif korelasional dengan sampel 160 guru dari seluruh sekolah menengah kejuruan negeri di Kab. Pekalongan. Teknik pengambilan sampel menggunakan teknik pengambilan acak yang semua uji korelasinya menggunakan bantuan program SPSS. Hasil penelitian menggambarkan bahwa terdapat korelasi yang signifikan antara disiplin kerja (X1) terhadap kinerja pembelajaran sains (Y) sebesar 56,6% dengan dimensi yang paling lemah adalah taat aturan waktu, korelasi antara motivasi kerja (X2) terhadap kinerja pembelajaran sains (Y) sebesar 8,9% dengan kelemahan pada dimensi motivasi intrinsik, dan korelasi yang signifikan antara kedua variabel X1 dan X2 secara bersamaan terhadap kinerja pembelajaran sains (Y) di SMKN se Kab. Pekalongan sebesar 56,2% dengan persamaan regresi ?= 18,787 + 2,083 X1 + 0,154 X2. Berdasarkan hasil penelitian, peneliti memberikan rekomendasi bahwa guru hendaknya meningkatkan kedisiplinan, motivasi, prestasi dalam melaksanakan pekerjaan dengan penuh rasa tanggung jawab dan pimpinan sekolah senantiasa memantau kinerja guru dalam pembelajaran sains dan memberikan dorongan supaya para guru termotivasi dalam meningkatkan disiplin kerja. selain itu, Pemerintah hendaknya memberikan pembinaan intensif kepada sekolah terkait kedisiplinan dan menganggarkan dana untuk kegiatan yang menumbuhkan motivasi guru untuk berprestasi dan meningkatkan kinerjanya.

Abstract

Linear algebra is a compulsory subject in Computer Systems which has 3 credits. This course is a new course in semester 2 and includes material on vector concepts in R2 (two dimensions) and R3 (three dimension), Euclidian vectors, general vector spaces, inner product spaces, orthonormals and equations of vectors. The teaching materials used were PPT slides compiled from various sources, both from textbooks and from the internet. This study aims to determine the linear algebra material that needs to be developed for students majoring in Computer Systems in offline learning. The subjects in this research were Computer Systems students who are taking linear algebra courses for the 2021/2022 academic year. Data were collected in the form of student test results and questionnaires given openly and then analyzed descriptively qualitatively. The results of the study indicate the need for teaching materials that are easily understood by students in solving problems and in accordance with current technological advances. Teaching materials in the form of e-modules can be used as an alternative to support learning in the classroom and can be accessed at any time.
