This development research aims to produce teaching materials in the form of handouts for teachers in Al-Kautsar Indralaya Islamic Kindergarten. Development is done by using ADDIE model (analysis, design,development, implementation and evaluation). The evaluation was done by Tessmer's formativeevaluation with four evaluation phases, namely self evaluation, expert review, one-to-one evaluation andsmall group evaluation. Data collection techniques use observation and walkthrough. Experimental resultsHandout 1 of 3.75, Handout 2 of 3.75, Handout 3 of 3.80, Handout 4 of 3.65, Handout 5 of 3.75 andHandout 6 of 3.80 (with very valid category) . Furthermore, the one to one evaluation stage obtained theaverage of teacher observation with Handout 1 of 87%, Handout 2 of 88%, Handout 3 of 87%, Handout 4of 90%, Handout 5 of 87% and Handout 6 of 88% with excellent category). While in the small groupevaluation, the average observation result on Handout 1 of 90%, Handout 2 of 90%, Handout 3 of 92%,Handout 4 is 90%, Handout 5 of 88%, and Handout 6 of 90% (with excellent category).

This study aims to produce worksheets for students of scientific-based measurement material in group B children in kindergartens that are valid and practically tested. This type of research is the development using the Rowntree model, namely the planning, development, evaluation stages. Evaluation using Tessmer's formative evaluation methods includes self evaluation, expert review, one to one evaluation, and small group evaluation. Analysis of data from expert reviews obtained an average of 87% with valid categories including validation of content, constructs and media. This means that the LKPD is in accordance with the contents of the measurement material for group B children, then the construct includes the readability and suitability of the image, while the media is seen from the packaging of the student worksheet (LKPD), display design, use of fonts and font sizes and illustrations of student worksheets (LKPD). In the one to one evaluation and small group evaluation and product stages the average percentage was 94% with a very practical category. To achieve a valid and practical LKPD perfection there is still a recognized lack of validity of 13% and to achieve practicality still have a deficiency of 6%

This study aims to produce Student Worksheets (LKPD) Development Of Work Sheets Of Participants In The Material Of Geometry Forms Based On Saintifices In Group B Children In Kindergarten which are valid and practical. Development is carried out using the Rowntree model, namely planning, development, evaluation. Evaluations carried out using Tessmer formative evaluation methods include self evaluation, expert review, one to one evaluation and small group evaluation. Data analysis from expert review obtained an average percentage of 94.5% with very valid categories which included the validity of content, constructs and media. This means that the LKPD is already in content, which is in accordance with the material for children in group B, including connecting one object with other objects in the same shape. Then the construct includes a scientific approach and assessment in accordance with the characteristics of child development. While the media can be seen from the completeness of the elements in the LKPD, images, writing and appearance. In the one to one evaluation and small group evaluation and product stages the average percentage was 96.2% with a very practical category. This means that LKPD is easy to implement, easy to check and the costs used are not too high. In order to achieve a valid and practical LKPD perfection, there is still a recognized lack of 5.5%. In material matters, namely the lack of use of the trapezoidal shape and parallelogram, the material is dominated by square, rectangular and circular shapes. The lack of media is that there are some words that are not familiar to children in group B, for example the scientific word. Whereas practically there is still a deficiency of 3.8%, namely the high cost of design. For this reason, further research is recommended to develop parallelogram and trapezoidal material and simple designs.

This research aimed to produce a product in the form of problem-connections of students mathematical was valid and practical (legible). This method of research was research and development. The research was conducted in Bengkulu City with the research subject of 6 students of grade VIII junior high school students and was carried out in May-June 2020. The method of data collection in development was carried out using Tessmer’s, which consists of preliminary, self-evaluation, expert review, and one-to-one. In the preliminary, two stages must be passed, namely preparation from completion. Was analyzing the curriculum, students, and material. Then, the completing the results of the students, curriculum evaluation, and the material was used as a reference for designing the mathematical connection ability, from the solution it produces 20 prototypes which are then assessed and fixed on self-evaluation. Of the 20 prototypes, these items will go through the validation stage (expert review) after 3 validation. Then, obtained 14 valid prototype items based on quantitative and qualitative analysis and test on 6 students to see the practicality or readability of items (one-to-one). The one-to-one stage was carried out to get comments on each question item to be analyzed qualitatively and quantitatively. Based on the qualitative comments, most of the provided students already understand the problem (legible) according to data, the average preceding data (legible) was recorded in the description of the pre-emptive questions at intervals of 4 ≤ RPproduc ≤ 5.
