This article aims to synthesize literatures in Educational Robotics and presents key features of systematic literature review and structured meta-analysis of the literature. Population consists of 247 papers from 10 databases ranging from 1996 to 2012. Results show that common problems in Educational Robotics are high cost of tools license and differences in students’ background knowledge. Trends of existing researches focus on development of software and low cost robot training package in order to promote students’ practice in problem-solving skills and teamwork in experience-based learning to enhance self-motivation and experience with real world applications. It was also found from the synthesis that qualitative-based evaluation of tool and learning achievement process was rare even though it is a key factor that indicates quality of learning process.

This paper aimed to study the process of making instant Pad Thai powder by Spray Drying method. The appropriate temperature of hot gas and the quantity of Maltodextrin in processing instant Pad Thai powder by Spray Drying method were studied. Factorial in Completely Randomized Design (CRD) was used. The study found that the appropriate quantity of Maltodextrin was 20% and the appropriate temperature for in and out hot gas was 150/90 ºC. The color variation of the finishing instant Pad Thai powder was as follow: Bright colors L* 88.32 Red a* 0.99 Yellow b* 8.26. The color variation after cooking the product was: Bright colors L* 30.73 Red a* 3.08 Yellow b* 8.25. aw 0.22. The moisture of the powder was 1.24. Then the consumer satisfaction was studied by using 3 types of Pad Thai Noodles; Pad Thai Noodles with Instant pad Thai Powder Pad Thai Noodles with regular Pad Thai sauce and Pad Thai Noodles sold in general market. Randomized Complete Block Design RCBD was used. The study of the consumer satisfaction revealed that there was no difference between pad Thai Noodles made with Instant Pad Thai Powder and Pad Thai Noodles made with regular Pad Thai sauce at the statistical significance (p>0.05). The testers rated the overall taste of Pad Thai Noodles at 7.57. Next the researcher studied the expiration period of Instant Pad Thai Powder by packing the product in double vacuum foil and storage the product at 4 different temperatures 30 35 45 and 55 degree Celsius. Then the product was studied to evaluate the physical chemical microorganism and sensory property. The product kept at 55 ºC was the most different of the four storage products at p ≥ 0.05 with the highest level of consumer satisfaction at color = 7.33 smell = 7.30 taste = 7.90 texture = 7.57 and total = 7.40. The amount of microorganism yeast and fungus were at the safe level to comsume.
