This research aimed to : 1) study the constructivist teaching method through cooperative learning activities to enable students’ self-instruction 2) to design the cooperative teaching and learning model based on the constructivism for the information literacy and research skills course for the students at Rajamangala University of Technology Phra Nakhon and 3) to develop the constructivist-cooperative teaching and learning instruction to develop critical thinking and learning achievement for the information literacy and research skills course at Rajamangala University of Technology Phra Nakhon. This research used a mixed-method between quantitative research and qualitative research. The data were collected from 30 students using the questionnaire approved by the experts. The in-depth interviewed data from five students who were fast acute and adept learners were analyzed and processed. The computerized statistics were percentage mean and standard deviation. The qualitative data were analyzed for content (Content Analysis). The findings showed that the students had the opinion at a high level about the model of constructivist-cooperative teaching and learning model in the information literacy skills course. Regarding each aspect it was found that the students were extremely satisfied with the constructivist-cooperative teaching and learning model. The following satisfaction lied in the development of the teaching and learning model and the trial of the model conducted with real students to see any potential flaws for further improvement and development of appropriate and effective instruction models. In addition the opinions of the informants were accordant with those of the students. The model should focus on the content and the instruction design. Group works should be used so that students can help each other. Experts in constructivism should play a main role in the development of a constructivist-cooperative instruction model. The constructivist-cooperative instruction model should be implemented with real students. The results can be further used for improvement and development of appropriate and effective instruction models.

This research is a qualitative research. The objective is to study and analyze information about The pattern of Pha Sin Tin Jok (Traditionally Sarong )Thai Yuan Saraburi cloth including the changes and the existence of the Thakok Thai Sarong Saraburi in the present (2017 - 2018). Using the concept of social and cultural change and the theory of globalization concepts for analysis. Research area is Mueang District and Sao Hai District Saraburi. The research population is Weaving sarongs Sarong user and local sages. Analytical study issues are Clothing culture in Thailand Saraburi Promotion from the government Pha Sin Tin Jok (Traditionally) Sarong Thai Yuan Saraburi style and pattern weavers and wisdom transfer. The research results are Saraburi is a province where Thai Yuan people from Chiang Saen Chiang Rai province Settled in the reign of King Rama I of Rattanakosin Due to war and have inherited the lineage until now.

This research aims to study the properties of local plants Phraek Nam Daeng community for the development of a herbal drink and development drink herbal tea. Local plants used in the study was Khlu (Pluchea indica (L.) Less). The leaves Khlu tested phytochemical composition antioxidant testing by testing their ability to reduce the amount of chemicals 11-diphenyl-2-picrylhydrazyl (DPPH) tests the amount of phenol used Folin-Ciocalteus reagent nutritional analysis and the amount of cellulose and developed the herbal drink tea. The research found that 1. Phytochemical composition of Khlu leaf is mainly flavonoids and tannins anthracnones. 2. Extracted from the leaf extract with methanol showed the ability to reduce the amount of substance 11-Diphenyl-1-picrylhydrazyl (DPPH) was the most abundant. Fresh leaves dried leaves and dried leaves were 30 days values at 131.23 ± 1.42 127.55 ± 1.03 and 125.90 ± 1.28 μg / ml respectively. 3. Extracts from the leaf extract with methanol showed the highest phenolic content as follows: fresh leaves dried leaves and dried leaves for 30 days were 84.91 ± 0.54 82.44 ± 1.09 and 81.01 ± 1.25 mg GAE / g dw respectively. 4. The optimal conditions for the process of making Khlu tea is a temperature of 70 °C for 7 hours. The score of sensory evaluation in terms of appearance color aroma flavor (astringent) and overall were 7.37 ± 1.22 7.23 ± 1.16 6.97. ± 1.30 7.00 ± 1.14 and 7.63 ± 1.10 respectively.

This research aims to study phytochemicals and potential of Mapok (Parinari anamense Hance) extracts to inhibit germination and growth of Barnyard grass (Echinochloa crus-galli) a common weed in the rice fields. Organic solvents extracted the part of fruits barks and leaves of Mapok included hexane ethyl acetate and methanol. Crude extracts compose of fruit hexane extract fruit ethyl acetate extract fruit methanol extract bark hexane extract bark ethyl acetate extract bark methanol extract leaves hexane extract leaves ethyl acetate extract and leave methanol extract. Crude extracts were tested of phytochemical tested of germinating inhibition root length inhibition stem length inhibition and dry weight inhibition of Barnyard grass. Leaves ethyl acetate extract showed highest inhibit germination and growth of Barnyard grass The leave ethyl acetate extract was separated by column chromatography to yield nine fractions (F1 – F9 fraction) and tested inhibit germination and growth repeating. The results showed that 1. The crude ethyl acetate extracts from the bark of Mapok at a concentration of 3000 ppm showed the highest inhibited percentage of germinating inhibition root length inhibition stem length inhibition and dry weight inhibition. 2. Fraction F8 of leaves ethyl acetate extract showed the highest inhibited percentage of germinating inhibition root length inhibition stem length inhibition and dry weight inhibition.
