In this paper the authors evaluate 85 elementary education teacher candidates' integration of technology into interdisciplinary units that the candidates wrote during the semester before their full-time student teaching internship. An inductive analysis of the units revealed that teachers used a wide variety of technologies with a large dependence on Internet-based technologies, interactive whiteboards, and iPad applications. Further analyses found that most of the technology uses were lower-level and focused on only basic skills. However, chi-squared tests for independence found statistically significant relationships between numerous factors and when technology was used in ways that addressed higher-order thinking skills. These factors included the structure of the lesson plans, the content of the interdisciplinary units, when the technology was integrated into the multi-lesson unit, and when the technology was integrated into specific phases of the lesson. Implications for teacher education programs and research that focuses on teacher candidates' TPACK are provided.
