Teachers' learning to facilitate high‐level student thinking: Impact of a video‐based professional development

Attaining the vision for science teaching and learning emphasized in the Framework for K‐12 Science Education and the next generation science standards (NGSS) will require major shifts in teaching practices in many science classrooms. As NGSS‐inspired cognitively demanding tasks begin to appear in more and more science classrooms, facilitating students' engagement in high‐level thinking as they work on these tasks will become an increasingly important instructional challenge to address. This study reports findings from a video‐based professional development effort (i.e., professional development [PD] that use video‐clips of instruction as the main artifact of practice to support teacher learning) to support teachers' learning to select cognitively demanding tasks and to support students' learning during the enactment of these tasks in ways that are aligned with the NGSS vision. Particularly, we focused on the NGSS's charge to get students to make sense of and deeply think about scientific ideas as students try to explain phenomena. Analyses of teachers' pre‐ and post‐PD instruction indicate that PD‐participants began to adopt instructional practices associated with facilitating these kinds of student thinking in their own classrooms. The study has implications for the design of video‐based professional development for science teachers who are learning to facilitate the NGSS vision in science classrooms.     

Defining attitude for science educators

A distinct and complex definition of attitude is evolving within the literature. A mental readiness to respond and a correlational consistency between attitude and behavior—although controversial and in need of further study and analysis—remain viable subcomponents within the definition. Most agree that evaluation is the heartbeat of attitude. The impact of social influence on attitudes is becoming increasingly important. Attitudes are learned and not inherited.     

Creating a space where teachers can locate their voices and develop their pedagogical awareness

The claim is made here that we need to prepare teachers who can locate their voices in teaching situations, recognize their relationship with other voices in those situations, and reflect on their pedagogical intentions. In a teacher education course, stories written about practicum experiences offered students an opportunity to reflect on the location of their voice in classroom situations and to discuss with peers different classroom situations and possibilities for teaching and learning. This study examines more closely the reflections of two of the students with seemingly distinct orientations to learning to teach. Their practicum stories and reflective essays were analyzed for positioning of voice as described by Belenky et al. (1986). The two students located their voices in distinct ways, and also expressed growing awareness of classroom dynamics and the value of peer dialogue in broadening and deepening their understandings of teaching and learning.     

Value transfer in concurrent-schedule discriminations by pigeons

When pigeons are trained on a discrete-trial simultaneous discrimination, some of the value associated with the positive stimulus appears to transfer to the negative stimulus (Zentall & Sherburne, 1994). Pigeons preferred a negative stimulus that had been discriminated from an always-positive stimulus (S+) over a negative stimulus that had been discriminated from a sometimes-positive stimulus (S±). A very different finding (suggestive of transitivity of preference or contrast) was reported by Belke (1992). On concurrent probe tests of stimuli associated with equal variable interval (VI) schedules but originally trained in alternative concurrent pairs (one with a richer schedule, the other with a poorer schedule—VI 20 sec vs. VI 40 sec and VI 40 sec vs. VI 80 sec), the stimulus originally paired with the poorer schedule was preferred. But Belke’s results may have been obtained because the pigeons had been trained to peck the VI 40 sec paired with the poorer schedule and they had been trained not to peck the VI 40 sec paired with the richer schedule. In the present experiment, we avoided this bias by training pigeons on two concurrent schedules in which the tested stimuli both had been associated with the poorer schedule of the pair [A(VI 20 sec) vs. B(VI 80 sec) and C(VI 40 sec) vs. D(VI 80 sec)]. Evidence for value transfer was demonstrated when on probe trials pigeons preferred B over D.     

Antecedents of college students' study deficiencies: the relationship between course features and students' study activities

Students entering institutions of higher learning have been observed to be deficient in the skills and dispositions necessary for engaging in sustained autonomous study. Evidence from investigations comparing instructional features and students' study activities across different courses and grade levels suggests that (a) particular features of courses may act to prompt or inhibit the development of proficiency at academic studying; and (b) the difficulties experienced by postsecondary students may be traced to certain discontinuties between characteristics of courses at the secondary versus post-secondary levels. These discontinuities can be described in terms of three dimensions: (a) differences in the demands made on particular study activities associated with different coursework requirements; (b) the degree to which instructors provide supportive practices designed to facilitate or sustain students' productive study activities; and (c) the prevalance of teaching strategies designed to compensate students for their study deficiencies. Using evidence from extant research on studying and results from recent investigation of secondary-level courses, the claim is made that particular patterns of instructor-implemented demands (workload, test difficulty, and latitude for self-direction) and compensations (test review practices, overlap between test items and instructor handouts, and the presence of safety nets) might account for deficiencies in the study activities of postsecondary graduates. Further, improving the level of preparedness of secondary-level graduates for the demands associated with higher education courses is discussed in terms of the need for the provision of particular support practices (e.g., feedback, clear performance expectations, and guided practice) in secondary-level courses.
