Abstract Teacher self-evaluation is an important dimension in the overall evaluation activities in educational programs. However, this dimension is often overlooked and not given its right share of importance. Teacher self-evaluation is neither included in teacher training programs nor is considered a basic requirement from teachers as they develop in their careers. The significance and value of teacher self-evaluation as a core element in continuing professional development requires that self-evaluation proceed all other forms of evaluation. To support the claim that teacher self-evaluation is a missing element in the area of investigation, the researchers conducted a study which adopted a survey that involved eleven schools and 86 Libyan teachers. The results of the study showed that while many teachers perform some sort of self-reflection about their teaching, they do not recognize self-evaluation as a basic requirement in developing their career. When the effectiveness of teacher self-evaluation was probed in contrast to external evaluation, most teachers agreed that teacher self-evaluation could play a far more vital role in continuing professional development. Keywords Continuing Professional development, External evaluation, Self- evaluation.

Seabird feathers and eggshells are used as bio-monitors for trace metal contamination. Eleven trace element concentrations in wing primaries (n = 21) and eggshells (n = 8) are reported herein for two resident seabirds, Bridled Tern Onychoprion anaethetus and Black-naped Tern Sterna sumatrana, at Pulau Ling and Pulau Tokung Burung, Malaysia. Metal concentration followed the pattern Zn > Cr > Mn > Sr > Cu > Se > Ba > Pb > Cd > Ga > Li. Significant positive correlations existed among all trace metals, except for Cr in Black-naped Tern and Li and Cd in Bridled Tern feathers. We also analyzed metal concentrations in eggshells, and for Bridled Tern, the concentration pattern was Zn > Mn > Se > Sr > Ba > Pb > Co > Cu > Cd, whereas for Black-naped Tern it was Cr > Zn > Mn > Ba > Sr > Se > Cu> Co > Pb. A pairwise positive correlation was significant among most trace metals in feather samples, indicating synergistic effects of two or more elements. More studies are needed to build a baseline database of trace metal concentrations in seabirds of Southeast Asia, as little research on this subject has been conducted in this region.
