An executable service composition code automatic creation tool based on Petri net model
For Web services composition problem, this paper proposes an executable code creation algorithm to model Web services composition based on Petri net model, and develops an executable composition code automatic creation tool. This tool can achieve the automatic creation process from composition model to executable code, and more meaningfully makes it possible to analyze and validate composition process logically. Finally, experiment results have proven that the tool of this paper is feasible.This work is partially supported by National Natural Science Foundation of China

The initial training of science teachers in African countries: a systematic literature review
Copyright: © 2021 by the authors. This study presents a systematic literature review (SLR) on the initial training of science teachers in Africa based on selected research articles, in the period 2000–2020, that emphasize the importance of surveying knowledge that goes beyond those that historically have a longer path in the building of scientific knowledge, such as that of European or North American countries. The analysis included a total of 31 articles from the Web of Science (WoS) and Scopus databases. The findings indicate a lack of knowledge, or at least visibility, considering the initial training of African teachers, particularly in developing countries. South Africa leads the number of publications. Within the five African countries implied in the SLR the following outputs were identified: (i) a division between teacher education research that is ‘place-based’ and one that uses (only) ‘universal theories’ (such as Vygotsky and Bandura); (ii) a tension between the application of student-centered learning and teaching models and more traditional classroom practices. Finally, the majority of articles highlight the importance of investing in further research around teacher education. Based on these outputs the importance of international cooperation in teacher education research articulating theory and practice to ensure a global and local perspective towards sustainable development is reinforced.This work is funded by National Funds through FCT - Foundation for Science and Technology, I.P. under project UIDB/00194/2020 and CEECIND/03328/2018.

Unifying an Introduction to Artificial Intelligence Course through Machine Learning Laboratory Experiences
This paper presents work on a collaborative project funded by the National Science Foundation that incorporates machine learning as a unifying theme to teach fundamental concepts typically covered in the introductory Artificial Intelligence courses. The project involves the development of an adaptable framework for the presentation of core AI topics. This is accomplished through the development, implementation, and testing of a suite of adaptable, hands-on laboratory projects that can be closely integrated into the AI course. Through the design and implementation of learning systems that enhance commonly-deployed applications, our model acknowledges that intelligent systems are best taught through their application to challenging problems. The goals of the project are to (1) enhance the student learning experience in the AI course, (2) increase student interest and motivation to learn AI by providing a framework for the presentation of the major AI topics that emphasizes the strong connection between AI and computer science and engineering, and (3) highlight the bridge that machine learning provides between AI technology and modern software engineering
Building Bridges Toward Science Careers for Youth with Disabilities
Several researchers have addressed the issue of accommodating students with disabilities in college science classrooms (Brazier, Parry, & Fischbach, 2000; Womble & Walker, 2001). However, little research has focused on the types of accommodations and supports needed for students with disabilities at the college level (Stodden, 2000). This brief outlines results of research conducted by the Bridges Project funded by the National Science Foundation Program for Persons with Disabilities. The major goals of the project were (a) to create a model facilitating greater access for students with disabilities to postsecondary education and careers in science and technology, and (b) to investigate issues related to the transition from high school to college for students with disabilities
