Student worksheets are guidelines used by teachers and students in practicum activities. This study aims to analyze and reconstruct the students worksheets are less qualified and not in accordance with established standards. This research is a descriptive qualitative analysis research which aims to analyze and reconstruct student worksheets with the 1)Analysis; 2)Try; 3)Reconstruction stage. The analysis was conducted on 6 student worksheet on Plant Network Structure and Function based on the KTSP Curriculum and 2013 Curriculum using the Laboratory Activity Analysis Form instrument and the Vee Diagram scoring table. The trial was conducted at the FPMIPA Plant Structure Laboratory, Universitas Pendidikan Indonesia. Student worksheets  reconstruction is based on the problems found in the conceptual, practical and knowledge construction aspects after analysis and testing. The results showed that there were problems with student worksheets  in the Structure and Function of Plant Tissue from conceptual, practical and knowledge construction aspects. In the conceptual aspect, for the suitability of competence with Basic Competence and suitability of activities with the cognitive level of students, the percentage is only 16.6%. In the practical aspect 66.7% of the student worksheets  analyzed the procedure incorrectly so that the phenomenon objects that appear are not relevant to the objectives / titles of student worksheets . In the aspect of knowledge construction 66.6% of student worksheets  analyzed the questions can be answered without doing practicum and there are no questions about data interpretation, the emergence of a principle and analysis so that drawing conclusions is not based on facts and does not describe the title/purpose. Based on the acquisition of component scores Diagram Vee student worksheets  Structure and Function of Plant Tissue has not reached an ideal score (18). The Vee Diagram component that does not appear at all is knowledge claims (score 0). Abstrak. Lembar kerja siswa merupakan pedoman yang digunakan oleh guru dan siswa dalam kegiatan praktikum. Penelitian ini bertujuan untuk menganalisis dan merekontruksi lembar kerja siswa yang kurang berkualitas dan tidak sesuai dengan standar yang telah ditetapkan. Penelitian ini merupakan penelitian analisis deskriptif kualitatif yang bertujuan untuk menganalisis dan merekontruksi lembar kerja siswa dengan metode ANCOR (Analisis-Coba-Rekontruksi). Analisis dilakukan pada 6 LKS Struktur dan Fungsi Jaringan Tumbuhan berdasarkan Kurikulum KTSP dan Kurikulum 2013 menggunakan instrumen Form Analisis Kegiatan Laboratorium dan tabel penskoran Diagram Vee. Uji coba dilakukan di Laboratorium Struktur Tumbuhan FPMIPA Universitas Pendidikan Indonesia. Rekontruksi LKS dilakukan berdasarkan permasalahan yang ditemukan pada aspek konseptual, praktikal dan kontruksi pengetahuan setelah melakukan analisis dan ujicoba. Hasil penelitian menunjukkan bahwa terdapat permasalahan pada LKS Struktur dan Fungsi Jaringan Tumbuhan dari aspek konseptual, praktikal dan kontruksi pengetahuan. Pada aspek konseptual, untuk kesesuaian kompetensi dengan Kompetensi Dasar dan kesesuaian kegiatan dengan tingkat kognitif siswa, persentasenya hanya 16,6%. Pada aspek praktikal 66,7% dari LKS yang dianalisis prosedurnya tidak tepat sehingga objek fenomena yang muncul tidak relevan dengan tujuan/judul LKS. Pada aspek kontruksi pengetahuan 66,6% dari LKS yang dianalisis pertanyaannya dapat dijawab tanpa melakukan praktikum dan tidak ada pertanyaan mengenai interpretasi data, kemunculan suatu prinsip dan analisis sehingga penarikan kesimpulan tidak berdasarkan fakta dan tidak menggambarkan judul/tujuan. Berdasarkan perolehan skor komponen Diagram Vee LKS Struktur dan Fungsi Jaringan Tumbuhan belum mencapai skor ideal (18). Komponen Diagram Vee yang tidak muncul sama sekali adalah klaim pengetahuan (skor 0).

This study examined children's drawings to explain children's conceptual understanding of plant structure and function. The study explored whether the children's drawings accurately reflect their conceptual understanding about plants in a manner that can be interpreted by others. Drawing, survey, interview, and observational data were collected from 182 students in grades K and 1 in rural southeastern United States. Results demonstrated the children held a wide range of conceptions concerning plant structure and function. These young children held very simple ideas about plants with respect to both their structure and function. Consistent with the drawings, the interviews presented similar findings.

This study aims to determine the differences in the average results of learning science the subject matter of the structure and function of plants between students whose learning uses a group investigation learning model with a model of picture and picture. This research includes field research, with the method used is comparative causal. The population of this study were all fourth grade students of SDN 45/1 Sridadi in the first semester of the 2014/2015 academic year, consisting of IV-A classes with 25 students, IV-B classes with 24 students. So the total population was 47 participants student. Because the population is less than 100, the entire population is sampled, with class IV-A consisting of 25 students as experimental class B and class IV-B consisting of 24 students as experimental class A. Data is collected by documentation method and test. The collected data were analyzed using statistical analysis of test differences in the average experimental class 1 (group investigation) and experimental class 2 (picture and picture) with the analysis of the two-party t-test test. Based on the results of the study it can be concluded that: the average science learning outcomes in the subject matter of plant structure and function of IV-A class students with the group investigation model is 84.44, while the average mathematics learning outcomes of students studying with a model of picture and picture is 77.29.

The purpose of the study was to determine the need for multireperentation modules to foster creative thinking skills in plant structure and function on science learning at junior high school. This research is a qualitative descriptive study. The method used in the online form of questionnaires for teacher and students. Data were analyzed using descriptive analysis and the percentage of the results of the number of answers given was divided by the total number of respondents multiplied by 100%. The results of this study indicate that: (1) 95.56% of teacher need a module as teaching material during COVID-19 Pandemic (2) 97.13% of students like teaching materials that contain multirepresentation (3) The reason of teacher need a multirepresentation module are guide for students in doing learning, facilitating distance learning, overcoming time constraints, making learning systematic and directed, representing the presence of teachers. The conclusion of this research is that it is necessary to develop teaching materials in the form of multireperentation modules to foster creative thinking skills in plant structure and function on science learning at junior high school.
