Description
The problem under investigation was to determine if a specific outline-style learning guide, called a Learning Agenda (LA), can improve a college algebra learning environment and if learner control can reduce the cognitive effort associated with note-taking in this instance. The 192 participants were volunteers from 47 different college algebra and pre-calculus classes at a community college in the southwestern United States. The approximate demographics of this college as of the academic year 2016 – 2017 are as follows: 53% women, 47% men; 61% ages 24 and under, 39% 25 and over; 43% Hispanic/Latino, 40% White, 7% other. Participants listened to an approximately 9-minute video lecture on solving a logarithmic equation. There were four dependent variables: encoding as measured by a posttest – pretest difference, perceived cognitive effort, attitude, and notes-quality/quantity. The perceived cognitive effort was measured by a self-reported questionnaire. The attitude was measured by an attitude survey. The note-quality/quantity measure included three sub-measures: expected mathematical expressions, expected phrases, and a total word count. There were two independent factors: note-taking method and learner control. The note-taking method had three levels: the Learning Agenda (LA), unguided note-taking (Usual), and no notes taken. The learner control factor had two levels: pausing allowed and pausing not allowed. The LA resulted in significantly improved notes on all three sub-measures (adjusted R2 = .298). There was a significant main effect of learner control on perceived cognitive effort with higher perceived cognitive effort occurring when pausing was not allowed and notes were taken. There was a significant interaction effect of the two factors on the attitude survey measure. The trend toward an improved attitude in both of the note-taking levels of the note-taking factor when pause was allowed was reversed in the no notes level when pausing was allowed. While significant encoding did occur as measured by the posttest – pretest difference (Cohen’s d = 1.81), this measure did not reliably vary across the levels of either the note-taking method factor or the learner control factor in this study. Interpretations were in terms of cognitive load management, split-attention, instructional design, and note-taking as a sense-making opportunity.

Description
This mixed methods action research study was conducted in a Title I, K-12 public charter school with the purpose of exploring teachers’ capacities to implement student-centered learning after participating in effective professional development (PD). Participants attended a PD cycle where the staff chose the topic, learning was sustained over a three-month period, and teachers received monthly feedback on classroom observations through personalized coaching. The guiding framework for this study was sociocultural theory because the PD design mirrored student-centered learning where the teacher is seen as a guide alongside the student. In this theory, meaning making is a social experience where perspectives of both the teacher and the student contribute to creating new knowledge. Quantitative data collected included a pre-/post-study survey and classroom observations scored on a rubric, and qualitative data consisted of exit interviews. All data was collected and analyzed concurrently, and a researcher’s journal assisted in real-time by providing a space for reflection that was used to determine PD needs, coaching conversations, and interview questions. Quantitative data revealed that the teachers perceived the intervention as slightly boosting their capacity to implement student-centered learning; however, the classroom observations indicated that teachers did not reach levels of proficiency. Through thematic analysis of the qualitative data, six themes emerged, which support the idea that PD can be a transformative experience when it is centered around praxis: 1) collaboration with colleagues, 2) PD gives teachers new ideas, 3) classroom feedback is valuable, 4) teacher reflection, 5) thought partnership, and 6) student choice. The discussion includes limitations and implications for future practice.
