Concept maps were used as a tool to solve problems in earth science and as a way to help students organize their ideas as a part of a three-part model, Real Engagement in Active Problem Solving (REAPS). Concept maps also were used to augment the National Science Foundation's (NSF) program — Full Option Science System (FOSS) for 3rd grade elementary students. We used two methods of assessment, Ruiz-Primo et al. (1997) and Novak & Gowin (1984). The results of the pre-post concept map assessment demonstrated that the students increased their content knowledge. Both the Novak and Ruiz-Primo methods showed an increase in accuracy of relationships and complexity of understanding of earth materials pre to post instruction. We also showed that the REAPS model enhanced the teacher's ability to teach the FOSS Earth Materials Unit and at the same time meet the Arizona State Standards in science and other non-science standards such as art, through model building. We concluded that to facilitate the use of concept maps in the classroom, teachers need more training and a simplified scoring system so they can easily score their students' progress when doing concept maps. From the practical point of view, we consider that more training and incorporation of practical activities is needed to prepare the students for concept mapping. Further research is needed to examine these possibilities.

During the Cultivating Diverse Talent in STEM (CDTIS) Project, a team of scientists, teachers, and a researcher developed a performance-based assessment of high school students’ creative problem-solving skills and ability to apply physical science principles in practical ways. It was one of six measures to identify exceptionally talented students. Students identified using conventional methods (M1), with an average grade point average (GPA) of 3.93, had an average rating of 2.95 on a 5-point scale on the mechanical–technical assessment. The M2 students, who were from schools with high percentages of Hispanic, American Indian, and low socioeconomic status (SES) students, had an average GPA of 3.07 and an average rating of 3.27, demonstrating that this assessment can be an important way to change the cultural and economic balance of students identified as exceptionally talented in Science, Technology, Engineering, and Mathematics (STEM). Other researchers are encouraged to examine the validity of the mechanical–technical assessment to identify exceptionally talented students in different groups.

Developing students’ strengths while teaching the content required by national and state standards in science, technology, engineering, and mathematics (STEM) is challenging for classroom teachers. In the Cultivating Diverse Talent in STEM (CDTIS) project, the assessment results found in strength-based reports gave teachers the tools needed to pursue STEM projects that were community and globally inspired, student selected, and aligned with standards. Results of Discovering Intellectual Strengths and Capabilities while Observing Varied Ethnic Responses (DISCOVER) assessments were compiled into easy-to-understand charts and profiles for each student and the class as a whole; the data from assessments of creative problem-solving in all domains were combined to show the students’ strengths. Profiles were then given to students and their parents. Reports contained a summary of the assessments, ideas for developing each area of strength, useful materials, ways to move from focusing on “right answers” to rewarding creative thinking, and careers aligned with the domains of ability. Teachers and students participated in Real Engagement in Active Problem Solving (REAPS) in which students solved real-world problems from their local communities and the world that were connected to their academic areas of study. Using REAPS in any STEM area boosts students’ focus, motivation, interest, and understanding.

In this qualitative study the researchers explored children's perceptions of their participation in a science class in which an elementary science curriculum, the Full Option Science System (FOSS), was combined with an innovative teaching model, Real Engagement in Active Problem Solving (REAPS). The children were capable of articulating views about their learning experiences during science classes. Meaningful experiences with deep levels of engagement were those that involved hands-on activities, such as experiments, provided by the FOSS curriculum; and problem-solving and model building, which were components of the REAPS model. Students' perceptions demonstrated in their drawings were similar to their interviews, which were evidence of their meaningful science learning experiences. Incorporating students' voices, as a type of feedback for teaching and learning, is important for teachers and practitioners; innovative pedagogical models contribute to meaningful and long-lasting science learning.
